Corporate profile
AngloGold Ashanti Limited is a leading global gold mining company, headquartered in Johannesburg, with a portfolio of
21 operations spanning 10 countries on four continents. For reporting purposes, operations are divided into five regions – Southern
Africa, Continental Africa, Australasia, North America and South America. In the company’s management structure, the African and
American operations fall under the executive vice presidents for Africa and the Americas respectively. The Australasian region is
similarly represented at executive level by a regional executive vice president.
As at 31 December 2009, AngloGold Ashanti had 362,240,669 ordinary shares in issue and a market capitalisation of
$14.6 billion (31 December 2008: $9.8 billion). AngloGold Ashanti’s primary listing is on the JSE Limited in Johannesburg.
It is also listed on exchanges in New York, London, Paris, Brussels, Australia and Ghana.
At the end of 2009, the government of Ghana held approximately 3% of AngloGold Ashanti’s shares. The balance of the
identifiable free float was held in the Americas (49%), South Africa (26%), the United Kingdom (12%), Europe (4%) and Asia
Pacific/the Middle East (3%).
In 2009, approximately 40% of AngloGold Ashanti’s production came from Southern Africa, including Namibia. Production
from the rest of Africa (Ghana, Tanzania, Guinea and Mali) made up a further 33%, South America (Brazil and Argentina) 13%,
North America (USA) 5% and Australasia (Australia) 9%.
The bulk of AngloGold Ashanti’s operations are under its own management. Typically contractors are used for mining activity
as a means of leveraging industry expertise, particularly at open-pit operations. In 2009 AngloGold Ashanti employed 63,364
people around the world, comprising 49,908 employees and 13,456 contractors.

Products and markets
In 2009 AngloGold Ashanti produced 4.599Moz (143,049kg) of gold, making the company one of the world’s leading gold
producers. To put this figure in perspective, total gold production in 2009 was estimated to be some 82.1Moz (2,533t).
AngloGold Ashanti’s own customers are typically banks acting as intermediaries in the supply chain. Sales take place either
directly to these customers or to Rand Refinery Limited, a South African-based refining company which buys gold from
AngloGold Ashanti either on its own account or acts as an agent for the company.
The geographical distribution of sales shown below reflects these arrangements and is based on the domicile of our
immediate customers. It does not necessarily reflect the location of the end-user of the product. The largest end-use markets
for gold are India, the Middle East, China and the USA.
Although the bulk of AngloGold Ashanti’s revenue (96%) comes from gold, the company also produces uranium from its
operations in South Africa, silver from its operations in Argentina and sulphuric acid from its operations in Brazil.
Exploration for future growth
The company is well positioned for future growth through substantial greenfields and brownfields exploration project pipelines.
AngloGold Ashanti’s track record of exploration discoveries compares favourably with its peer group: it has recorded five major
finds since 2003, including in Colombia, Brazil, Australia and the Democratic Republic of the Congo (DRC). Currently, the
company’s largest greenfields exploration projects are based in Western Australia, Colombia and the DRC. At 31 December 2009,
the group’s Proved and Probable Ore Reserves amounted to 71.4Moz of gold (2008: 74.9Moz).

Mineral Resource
When the 2008 Mineral Resource is restated to exclude the sale of Boddington (11.9Moz) and the purchase of Kibali (10.1Moz)
the Mineral Resource is reduced from 241.0Moz to 239.2Moz. The total Mineral Resource decreased from 239.2Moz in 2008
to 226.7Moz in December 2009. A year-on-year decrease of 6.3Moz (-3%) occurred before the subtraction of depletion and
a decrease of 12.5Moz (-5%) after the subtraction of depletion.
It should be noted that the changes in economic assumptions from 2008 to 2009 resulted in the Mineral Resource decreasing
by 2.8Moz whilst exploration and modelling resulted in an increase of 3.5Moz. The remaining loss of 6.9Moz resulted from
various other reasons. Depletions from the Mineral Resource for 2009 totalled 6.2Moz.

When the 2008 Ore Reserve is restated to exclude the sale of Boddington (6.7Moz) and the purchase of Kibali (2.5Moz), the
2008 Ore Reserve is reduced from 74.9Moz to 70.7Moz. Using the restated figure, the total AngloGold Ashanti Ore Reserve
increased from 70.7Moz in 2008 to 71.4Moz in December 2009. A year-on-year increase of 6.0Moz (8%) occurred before the
subtraction of 5.2Moz for depletion, resulting in an increase of 0.8Moz (1%) after the subtraction of depletion.
It should be noted that the changes in the economic assumptions from 2008 to 2009 resulted in the Ore Reserve increasing
3.2Moz while exploration and modelling resulted in a further increase of 2.7Moz.

South Africa
Regional overview
The South African operations comprise seven underground mines located in two geographical regions on the Witwatersrand
Basin called the Vaal River and West Wits operations.
The Vaal River operations consist of the Great Noligwa, Kopanang, Moab Khotsong and Tau Lekoa mines. The primary reefs
mined in this region are the Vaal Reef (VR) and the Ventersdorp Contact Reef (VCR) and the secondary Crystalkop Reef
(C Reef).
The West Wits operations are made up of Mponeng, Savuka and TauTona, which are situated near the town of Carletonville.
The primary reefs mined are the Carbon Leader Reef (CLR) and the VCR.
All seven operations are 100% owned by AngloGold Ashanti. In addition, the Vaal River Surface and West Wits Surface
operations mine the waste rock dumps and tailings dams which result from the mining and processing of the primary and
secondary reef horizons.
The South African operations are all located in the rocks of the famous Witwatersrand Basin, which is regarded as the greatest
gold-bearing repository on Earth.
Geology of the Witwatersrand Basin
The Witwatersrand Supergroup (deposited in area often described as the Witwatersrand Basin) comprises a 6km-thick
sequence of predominantly argillaceous and arenaceous sediments that extend laterally for some 300km north-east/south-
west and 100km north-west/south-east on the Kaapvaal Craton. The upper portion of the sequence contains the laterally
extensive, gold-bearing quartz pebble conglomerate horizons (commonly referred to as “reefs”).
Further west, south and east the basin is overlain by up to 4km of Archaean, Proterozoic and Mesozoic volcanic and sedimentary
rocks. The Witwatersrand Basin is late Archaean in age and is considered to be around 2.7 to 2.8 billion years old.
The reefs, which are generally less than 2m thick, are widely considered to represent laterally extensive braided fluvial deposits.
Separate fan systems were developed at different entry points and these are preserved as distinct goldfields with local
geological variations. AngloGold Ashanti operates in two of these goldfields, known as the Carletonville (West Wits) and
Klerksdorp (Vaal River) goldfields.
There is still debate about the origin of the gold mineralisation in the Witwatersrand Basin. Gold was generally considered to
have been deposited syngenetically with the conglomerates, but increasingly an epigenetic theory of origin is being supported.
Nonetheless, the most fundamental determinant of gold distribution in the basin remains the sedimentary features, such as
facies variations and channel directions. Gold generally occurs in native form often associated with pyrite and carbon, with
quartz being the main gangue mineral.
West Wits operations
Two reef horizons are exploited at the West Wits operations: the VCR, located at the top of the Central Rand Group, and the
CLR near the base. The separation between the two reefs increases from north to south, from 400 to 900m, owing to non-
conformity of the VCR horizon. TauTona and Savuka exploit both reefs, while Mponeng currently only mines the VCR. The
structure is relatively simple, with rare instances of faults greater than 70m.
The CLR consists of one or more conglomerate units and varies from several centimetres to more than 3m in thickness.
Regionally, the VCR dips at approximately 21°, but may vary between 5° and 50°, accompanied by changes in thickness of
the conglomerate units. Where the conglomerate has the attitude of the regional dip, it tends to be thick, well-developed and
accompanied by higher gold accumulations. Where the attitude departs significantly from the regional dip, the reef is thin and
gold grades tend to be erratic.

Vaal River operation
In order of importance, the reefs mined at the Vaal River operations are the VR, the VCR and the C Reef:
The VR contains approximately 85% of the Ore Reserve tonnage with mining grades of between 10 and 20g/t gold and
comprises a series of oligomictic conglomerates and quartzite packages developed on successive non-conformities.
Several distinct facies have been identified, each with its own unique gold distribution and grade characteristic.

The VCR has a lower gold grade than the VR, and contains approximately 15% of the estimated Ore Reserve. The
economic portion is concentrated in the western part of the lease area and can take the form of a massive conglomerate,
a pyritic sand unit with intermittent pebble layers, or a thin conglomerate horizon. The reef is located at the contact between
the overlying Kliprivierberg Lavas of the Ventersdorp Super Group and the underlying sediments of the Witwatersrand Super
Group, which creates a distinctive seismic reflector. The VCR is located up to 1km above the VR.
The C Reef is a thin, small-pebble conglomerate with a carbon-rich basal contact, located approximately 270m above the
VR. It has less than 1% of the estimated Ore Reserve with gold grades similar to those of the VR, but less continuity. The
most significant structural features are the north-east striking normal faults which dip to the north-west and south-east,
resulting in zones of fault loss.

Mineral Resource estimation
A multi-disciplinary approach is adapted to Mineral Resource estimation whereby inputs are required from the geoscience,
survey and mine planning departments. A computerised system called the Mineral Resource Inventory System (MRIS)
integrates all the input information to produce the final Mineral Resource per operation. Mineral Resource estimates
are computed from a composite grid of value estimates, comprising various block sizes. The macro block sizes vary from
210m x 210m to 420m x 420m with micro blocks of 30m x 30m.
Compound lognormal macro co-kriging estimation techniques are used to produce estimates for the larger block sizes. This
technique uses the Bayesian approach whereby the assayed (observed) data in the mined-out areas are used to infer the
population characteristics of the area ahead of current mining. The geological model forms the basis for this estimation and all
surface borehole information from the peripheral areas of the mine lease play a crucial role in determining the geological model
boundaries. Simple kriging is used for the 30m block sizes and these estimates are constrained by the weight of the mean.
The Mineral Resource is initially reported as inclusive of the Ore Reserve as they form the basis for the Ore Reserve conversion
process. Mineral Resource cut-offs are computed by operation, for each reef horizon. These cut-offs incorporate a profit
margin that is relevant to the business plan. Mineral Resource grade tonnage curves are produced for the individual
operations, which show the potential of the orebody at different cut-offs. These curves are produced for dimensions equivalent
to a practical mining unit for underground operations.
Exclusive Mineral Resource
The Exclusive Mineral Resource is defined as the inclusive Mineral Resource minus the in-situ Ore Reserve before stoping
width, dilution and mine call factors (MCF) are applied. Scoping studies are conducted on this Exclusive Mineral Resource,
where capital requirements and current costs are used to test economic potential. If these studies show no reasonable
economic potential at the Mineral Resource gold price then the material is excluded from the Mineral Resource. All planned
pillars (ahead of current mining) form part of the Exclusive Mineral Resource.

Ore Reserve estimation
All mine designs are undertaken using the Cadsmine
®
software package and include the delineation of mining or stoping areas
for each mining level and section, usually leading from an extension to the existing mining sequence, and the definition of the
necessary development layouts. The in situ Mineral Resource is scheduled monthly for the full Life-Of-Mine (LOM) plan. The
value estimates for these schedules are derived directly from the MRIS.
Modifying factors are applied to the in situ Mineral Resource to arrive at an Ore Reserve. These factors comprise a dilution
factor to accommodate the difference between the mill width and the stoping width as well as the MCF.
Inferred Mineral Resource in business plan
The LOM plans include a minimal Inferred Mineral Resource.

Uranium
AngloGold Ashanti produces a uranium oxide concentrate (U
3
O
8
) as a by-product from its South African gold mining
operations. AngloGold Ashanti currently produces between 500 and 600t of U
3
O
8
annually. Although mined as a by-product
of gold for many years, U
3
O
8
was not considered a Mineral Resource until 2005. Due to the rapid increase in the U
3
O
8
price
over the last few years, renewed focus has been placed on the U
3
O
8
content within the Witwatersrand reefs.
The AngloGold Ashanti mines in the Vaal River region that currently produce uranium oxide as a by-product are Great Noligwa,
Kopanang, and Moab Khotsong. The uranium oxide is extracted from the VR, although Great Noligwa mine also produces
some uranium oxide from the C Reef. The mines in the West Wits region that have uranium Mineral Resources are Mponeng,
Savuka and TauTona and in this mining region the uranium is only present in the CLR and is currently not being extracted.
The mineralised ore from Moab Khotsong, Great Noligwa and Kopanang is milled in the Noligwa gold plant and treated in the
South uranium plant for uranium extraction by the reverse leach process. The ammonium diuranate is transported to Nufcor
where the material is calcined and packed for shipment to the converters.
The surface tailings storage facilities that have been classified as uranium Mineral Resources are the Kopanang Paydam and
the tailings storage facilities in the West Wits region. Uraninite and brannerite are the most common uranium-bearing minerals,
although uraniferous leucoxene and coffinite are also present. Uraninite was the original primary uranium-bearing mineral and
was possibly introduced as detrital material during the deposition of the Witwatersrand sediments.

South Africa – Great Noligwa
Location
Great Noligwa is located about 15km south-east of the town of Orkney, in the southern part of the Klerksdorp goldfield. The
mine exploits the VR at depths varying between 1,500 and 2,600m below surface. Scattered mining methods are employed
where access to the reef is from the footwall haulage and return airway development, with cross-cuts developed every 180m
to the reef horizon. Raises are then developed on-reef to the level above, and the reef is stoped out on-strike. The Great
Noligwa lease area is constrained to the north by Pamodzi gold mine, to the east by Buffelsfontein gold mine, to the south by
the Jersey and Die Hoek faults, (which displace the reef down by approximately 1,000 and 900m respectively), and to the
west by Kopanang.
Geology
The VR is the principal economic horizon at Great Noligwa, accounting for over 90% of the gold produced at the mine. The
VR is part of the Witwatersrand Supergroup and is stratigraphically located near the middle of the Central Rand Group in the
Johannesburg Subgroup on an unconformity below the Krugersdorp Formation. The VR unit can reach a maximum thickness
of more than 2m and consists of a thin basal conglomerate (the C Facies) and a thicker sequence of upper conglomerates
(the A Facies), separated by internal quartzite (the B Facies). Across most of the Great Noligwa lease area, the A Facies is the
principal economic horizon within the VR, although sporadic remnants of C Facies may be preserved below the A Facies. The
high gold values in the VR are often associated with high uranium values. Uranium is a very important by-product of Great
Noligwa.
The C Reef has been mined on a limited scale in the central part of Great Noligwa, where a high-grade, north-south orientated
channel containing two economic horizons has been exposed. To the east and west of this channel the C Reef is poorly
developed with relatively small areas of economic interest. High uranium values in the C Reef are also often associated with
high gold values. To the north, the C Reef sub-crops against the Gold Estates Conglomerates and in the extreme south of the
mine the C Reef has been eliminated by a deeply eroded Kimberley Channel and the Jersey fault.

Southern Africa – South Africa – Kopanang

South Africa – Kopanang
Location
Kopanang mine is located in the Free State province; roughly 170km south-west of Johannesburg and approximately 10km
south-east of the town of Orkney on the farms Pretoriuskraal 53 and Grootdraai 468. The mine has been in production since
1984 and was originally known as Vaal Reef’s 9 Shaft. Kopanang’s current mine lease incorporates an area of 35km
2
, directly
west of neighbouring Great Noligwa mine and bound to the south by the Jersey Fault. Dolomites of the Transvaal Supergroup
outcrop on surface resulting in a very subdued topography with very few rock exposures.
Geology
Gold- and uranium-bearing conglomerates of the Central Rand Group are exploited, the most important of which is the VR.
Gold is the primary commodity being extracted, with uranium oxide as a by-product. The economic VR and Crystalkop
conglomerates are exposed via a twin-shaft system that reaches a depth of 2,340m. The VR is exploited at depths of between
1,300 and 2,600m below surface. Kopanang almost exclusively exploits the VR, although minor amounts of gold are also
extracted from the C Reef, which is stratigraphically located about 250m above the VR.
The VR is a medium- to high-grade reef consisting of a basal conglomerate called the Stilfontein Reef, occasionally overlying
remnant Grootdraai conglomerate units, with an overlying Upper Vaal unit. Current terminology separates the reef into A, B
and C Facies, where the C Facies is the basal Stilfontein and/or Grootdraai conglomerates.
The overlying Upper Vaal or “A Facies” is split into three distinct sub facies; the VR A Bottom, Middle and Top, which consist
of a series of small pebble conglomerates and grits containing very little gold. Further to the east at Great Noligwa, the
A Facies becomes more robust and better developed and attains high gold values.
The B Facies is simply a fine-grained, cross bedded, light grey, black speckled orthoquartzite that separates the A and
C Facies.
The basal C Facies conglomerate of the VR is the main gold carrier on Kopanang. It varies very little in thickness, with a
thickness of 7 to 10cm being typical. The conglomerate comprises mostly quartz (92-98%) and chert (2-8%), with occasional
porphyry clasts (<2%). The matrix is generally very pyritic and the base is non-channelised, often containing a well-developed
carbon seam.
The C Reef contains two economic conglomerates, although the lower-most conglomerate is only preserved as small
remnants. Gold concentrations are typically associated with a basal carbon seam. The C Reef sub-crops in the north against
the Gold Estates Conglomerates Formation. To the south of this unconformity, the reef can be eliminated by either the
Kimberley erosion channels or bedding parallel faulting.
The VR and C Reef generally dip towards the south-east at between 10° and 30°.
Kopanang is situated in a structurally complicated area of the Witwatersrand Basin, which has been subjected to numerous
tectonic events. The complexity of the faulting at Kopanang became evident during initial surface diamond borehole drilling.
Prior to 1970, 12 surface boreholes had been drilled on the farm Pretoriuskraal 53 and only five of these intersected the VR,
the rest had been faulted out. Approximately 20% of the ground in the mine lease area has been eliminated due to
the presence of faulting. At least nine structural events, of differing ages, are thought to effect the reef at Kopanang.
The interaction of these structures can be very complicated as the relationship of different aged structures is made more
difficult by many of these faults having been reactivated at latter stages, or been active over long periods of time. This tectonic
time frame ranges from late Archaean to Cretaceous and therefore involves some 2.7 billion years of structural deformation.
Exploration
The exploration at Kopanang is focused around target blocks that will be explored from underground drilling. The VR target
blocks are situated in the shaft fault area and the ground below 68 level. Additional to this ground, the western portion of the
mine lease (Gencor 1E area) forms a potential mineable area and will be explored by a combination of exploration drilling and
development. An extensive C Reef exploration programme started during 2009 and will continue in 2010.

Southern Africa – South Africa – Moab Khotsong

South Africa – Moab Khotsong
Location
The Moab Project was approved in 1997 to exploit two distinct portions of the Moab lease area, namely the Middle Mine
(85 to 101 level) and the Lower Mine (101 to 118 level). During 2008, the SV4 section of Great Noligwa was incorporated into
Moab Khotsong and this section is now termed the Top Mine.
Geology
The Mineral Resource at Moab Khotsong is structurally complex and highly faulted, with large fault-loss areas. Mining is based
on a scattered mining method with an integrated backfill support system combined with bracket pillars. The raise lines are
spaced 200m apart on the dip of the reef, with 25m-long panels. Backfill is carried to within 4m of the advancing stope faces
and 75% of the total area extracted is likely to be backfilled.
The geological setting of Moab Khotsong is one of crustal extension, bounded in the north-west and south-east by major
south-dipping fault systems with north-dipping Zuiping faults sandwiched between them. The Die Hoek and Buffels East faults
structurally bound the reef blocks of the Moab Middle Mine to the north-west and south-east respectively. The northern
boundary is a Zuiping-type fault. The southern boundary fault of the Moab Middle Mine is currently not defined.
Due to the magnitude of throw across the Die Hoek fault, more than 700m down to the south, geological structures
encountered on the up-thrown side of the fault cannot be projected to the down-thrown side and vice versa. No information
pertaining to the reef blocks being accessed can be gleaned from the mapping of the access development. Only once the
development is through the Die Hoek fault does mapping have any bearing on the reef blocks, and even then a great amount
of exploration drilling is required to accurately delineate these blocks.
The C Reef is preserved in the northern part of the mine where the reef has been intersected by a number of boreholes.
No development or stoping has taken place on the C Reef at Moab Khotsong.
Project Zaaiplaats 2
Project Zaaiplaats 2 (PZ2) is situated at Moab Khotsong in the Vaal River region of AngloGold Ashanti’s South African
operations. Moab Khotsong is the newest mine in the region and the PZ2 project is aimed at optimally extracting the deeper
portion (lower mine) of the VR at Moab Khotsong. The PZ2 project is planned to extend the life of Moab Khotsong another
27 years until the mid-2030s. The project also allows other opportunities (mining and metallurgical) to come to the fore that
would otherwise have been uneconomic.
The Lower Mine orebody will be accessed via twin double-declines angled at 8º, the upper and lower declines, from which
five production levels will originate. These will allow two attacking points into the orebody, as well as providing sufficient
ventilation capacity. One of the lower declines will be a dedicated ore-handling system via a conveyor belt; each of the decline
sets will have a dedicated men and material decline (using chairlifts and a monorail) and the remaining upper decline will carry
the majority of the services into the orebody. Shaft bottom will be 4,027m below datum (3,509m below collar).
Brownfields exploration
Brownfields exploration is currently focused on improving geological confidence and four surface drilling machines, targeting
the Project Zaaiplaats Mineral Resource, were in operation during the year.
Surface drilling continued in the Project Zaaiplaats area (Moab Lower Mine), where the target is the prospective VR. Progress
is behind schedule due to in-hole problems.
Progress in the MZA9 long deflection to the east, intended to raise the confidence of an Inferred block in the north-east portion
of the Zaaiplaats project area and also to confirm the structure between the Middle and Lower mines, was delayed due to
caving problems. MHH2 is scheduled to commence on completion of MZA9.
In the north-west of the main Zaaiplaats block, MMB5 is drilling to test a proposed target block along the Jersey Fault
cut-off. Progress in Deflection 5, currently at a depth of 3,362m, was delayed by caving in the Kimberley Channel. The first
VR intersection is now expected during the first quarter of 2010.

Progress in MGR8, currently at a depth of 3,070m, was delayed by caving. The first VR intersection is now expected during
during the first quarter of 2010.
The long deflection of MGR6 was advanced to a depth of 2,152m in Ventersdorp lavas. The programme is currently ahead of
schedule and the first VR intersection is now expected in the first quarter of 2010.
Currently four LIB (long inclined boreholes) drilling machines are deployed at Moab Khotsong. The Moab Khotsong LIB drilling
programme can be subdivided into five primary categories:
upgrading the confidence in the level 1 structure to optimise the placement of the primary haulage systems;
proving up postulated reef blocks;
upgrading the confidence of the MKF1 Inferred Mineral Resource blocks of the Middle Mine below 101;
confirming the presence of the Project Zaaiplaats early gold block; and
confirming the presence of Inferred C Reef Mineral Resource in the Moab Khotsong area and upgrading the postulated
C Reef blue sky blocks to an Inferred Mineral Resource.

Exclusive Mineral Resource
The Exclusive Mineral Resource consists of designed rock engineering bracket pillars, designed dip pillars and the Great
Noligwa shaft pillar on the VR. The major portion (59%) of this Exclusive Mineral Resource is situated in the Lower Mine area,
with minor amounts in the Top Mine (7%), Middle Mine (29%), C Reef (2%) and shaft pillar (4%) areas. The bracket pillars are
designed for safety reasons and will therefore not be mined, whereas the shaft pillars can only be safely extracted at the end
of the mine life.

Southern Africa – South Africa – Tau Lekoa

South Africa – Tau Lekoa*
Location
Tau Lekoa is located about 8km west of the town of Orkney, at the western extreme of the Klerksdorp goldfields. The mine
exploits the VCR at depths varying between 900 and 1,700m below surface. The VCR, the only reef exploited at Tau Lekoa,
dips towards the west at an average angle of 28°. Tau Lekoa has a twin shaft system and mines to a depth of 1,650m.
Tau Lekoa uses hydropower and has a centralised electro-hydraulic system as its primary source of energy production.
Hydropower has been instrumental in improving labour productivity, which has played a vital role in assisting the mine to
achieve its business objectives.
Geology
The VCR is a gold-bearing quartz pebble conglomerate (up to 5m thick) capping the uppermost angular unconformity of the
Witwatersrand Supergroup. The topography of the VCR depositional area is uneven, and consists of a series of slopes and
horizontal terraces at different elevations. The VCR is deposited over a number of terraces that are separated by slope
material. Typically the terrace reef is a thicker, more robust conglomerate unit than the slope material, where hangingwall-
footwall conditions may occur. The deepest terraces are the youngest, whereas the oldest terrace occupies a topographical
horizon 28m above the youngest terrace. Generally the younger the terrace, the more mature the channel fill. The main
channel is the youngest, most mature VCR facies at Tau Lekoa, and extends from the north-east into Tau Lekoa, before
turning sharply towards the west. The older middle and upper terraces contain more immature conglomerates with more
erratic gold grades.
The Tau Lekoa orebody is disrupted by a number of dykes and faults. The major faults present tend to be normal, trending
northeast, and are of post-Ventersdorp age. Flats dipping normal and reverse faults of minor throw are also common. The
majority of major faults strike in a north-north-east to south-south-west direction and these include the Schoonspruit and
Nooitgedacht faults, both of which have displacements of over 100m. Low angle flat faulting affects the reef in the northern
and southern parts of the mine. In addition to this, there are also a number of intrusives present, which vary in age from pre-
Ventersdorp through to Karoo in age. These include the east-west striking Pickavance Dyke, which is associated with lateral
movement and the north-north-west to south-south-east striking incompetent running dykes.

Southern Africa – South Africa – Mponeng
P

South Africa – Mponeng
Location
Mponeng lies on the West Wits Line, close to Carletonville in the province of Gauteng, about 65km south-west of
Johannesburg and forms part of AngloGold Ashanti’s West Wits operations. Mining at Mponeng is conducted at an average
depth between 2,800 to 3,400m below surface. The mine operates two vertical hoisting shafts, a sub-shaft and two service
shafts. The Mponeng lease area is constrained to the north by the TauTona and Savuka mines, and to the south only by
the depth of the orebody, which is open-ended. In 2008, permission was granted to explore the Western Ultra Deep
Levels (WUDLS) portion to the south of the mine, increasing the potential Mineral Resource.
Geology
The VCR is the only reef currently being mined at Mponeng. The VCR comprises of a quartz pebble conglomerate (up to
3m thick) capping the topmost angular unconformity of the Witwatersrand Supergroup. The VCR is overlain by the
Ventersdorp Lavas which dramatically halted further reef development at that time. The footwall stratigraphy partially controls
the reef facies type and comprises of a series of argillaceous to proto-quartzites, shales and siltstones from the Central Rand
Group of the Witwatersrand Supergroup. The erosional nature of the deposition of the VCR means that the VCR is deposited
on these different Witwatersrand footwalls. The age of the footwall Witwatersrand rocks increases from west to east. Most of
the VCR mined lies on footwall strata of the Kimberley Formation, which is relatively argillaceous proto quartzite. The VCR is
dominated by a series of channel terraces at different elevations, separated by slopes where the reef channel widths are lower
and the angular unconformity between the footwall is larger than on reef terrace planes. More durable quartzites of the Elsburg
Formation lie to the west, while the eastern side of the mine is dominated shales and siltsones of the Booysens Formation.
The hardness of the footwall units influences the development of the terraces.

Mponeng is also planning to mine the CLR. The CLR at Mponeng is on average a 20cm thick, tabular, auriferous quartz pebble
conglomerate formed near the base of the Central Rand Group. The CLR is on average 900m deeper than the VCR. Major
exploration drilling started in early 2008 in order to improve Mineral Resource confidence and confirm the geological structures
that occur at the deep levels at which mining is planned. Of the three economic units that exist within the CLR, the Mponeng
CLR target area is dominated by unit 3 with a smaller portion of unit 2 towards the east. Unit 2 is a complex channel deposit,
and unit 3 is the oldest of the CLR channel deposits sitting at the base of the package.
Both orebodies are influenced by faulting as well as a series of intrusives of various ages that cross-cut the reefs. At these
depths there is a large amount of inherent risk in mining through these structural features. The Geoscience department’s primary
role is to identify these features ahead of the face so that the correct mining approach can be applied to minimise the risk.
CLR Project
Two economically viable reefs are mined in the West Wits area, the shallower VCR and the deeper CLR. Both have been
extensively mined at AngloGold Ashanti’s TauTona and Savuka operations, while Mponeng has only mined the VCR. Both
reefs can be accessed down to 120 level (3,645m below datum), but there is currently no infrastructure in place that can
service stoping operations below 120 level.
The high-grade CLR below 120 level has remained inaccessible and this represents a significant opportunity for Mponeng and
for AngloGold Ashanti. A series of exploration holes collared underground have drilled sub-vertical holes from current VCR
development towards the CLR to improve the confidence in the orebody. Information gained has been used to confirm the
geological structures at depth that may affect a proposed new shaft system as well as generate more confidence in the current
mineralisation and estimation models.
A project team has been set up to design a “new mine” to access the CLR via tertiary shafts from Mponeng, enabling the
mine to extend its life, while maintaining production at current levels. The mine has been designed according to the sequential
grid mining method, a technique developed at Elandsrand and Mponeng in the 1990s. This method involves pre-developing
stoping grids and extracting the reef between the dip-stabilising pillars. This method has proved successful in the
management of seismicity, both in reducing seismic energy and increasing mining flexibility. The shafts and infrastructure have
been designed to fit the existing shaft system at Mponeng, and have the capacity to sustain high levels of production.
The extension of Mponeng via the CLR project provides a strong base from which several regional benefits can be realised,
as well as enabling other smaller projects to be brought in to match the extended life of the asset and region. The approval
of a CLR project will compliment further exploration and development of the WUDLS mine plan.
The CLR in the deeper portion of the orebody (below 126 level) and the VCR in the north of the mine lease are also potentially
mineable areas.
During the year, surface drilling commenced in the WUDLS extension to the Mponeng mining rights area. Drillhole UD51 was
re-opened for deepening to test the VCR. By year end the drillhole had reached a depth of 2,692m.

South Africa – Savuka
Location
The Savuka mine is located about 18km south of the town of Carletonville, and forms part of AngloGold Ashanti’s West Wits
operations. The mine exploits the CLR at depths varying between 2,600 and 3,500m below surface as well as the VCR in
smaller proportions. The VCR, which is on average about 700m above the CLR has nearly been mined out. Currently
operations are attempting to extract remnant pillars that are above the current pay limit.
Savuka has converted into a sequential grid mine. CLR and VCR panels are mined accordingly.
Geology
The CLR is a thin, on average 20cm thick, tabular, auriferous quartz pebble conglomerate formed near the base of the Central
Rand Group. The CLR has been divided into three stratigraphic units. Economically the most important is unit 1 which is
present as a sheet-like deposit over the whole mine. Unit 2 is a complex channel deposit that is presently only being mined
along the south and west at Savuka. The reef may be over 2m thick where unit 2 is developed. Unit 3 is preserved below unit 1
in the southern parts of Savuka and is the oldest of the CLR conglomerates. The CLR has not been mined since 22 May 2009
due to a seismic event that left the lower levels inaccessible through the main shaft system. Production has since been
focused on extracting pillars of VCR.
The VCR comprises a quartz pebble conglomerate (up to 5m thick) capping the topmost angular unconformity of the
Witwatersrand Supergroup. The topography of the VCR depositional area is uneven, and consists of a series of slopes and
horizontal terraces at different elevations. The base of the Ventersdorp Lava strikes in a direction across the north-western
part of the lease area.
The orebody is cross cut by geological features that displace the reef horizon. The faulting, in conjunction with the numerous
intrusives that also intersect the orebody on the various levels, is responsible for most of the risk inherent with this type of
deep-level gold mining. There is also a high level of seismicity associated with these features.
Exploration
The Middelvlei Reef is another Witwatersrand auriferous placer mined in the West Wits. It is located approximately 90m above
the CLR stratigraphically. This reef comprises interbeds of quartz-pebble conglomerates, quartz wackes and thin siltstones.
The channel thickness varies up to a thickness of 1.6m, and the Middelvlei Reef is highly channelled with gold pay chutes
most likely occurring at the base of the channels. These trends are similar in direction to the palaeo-current directions of the
underlying footwall sequence. Middelvlei Reef has been mined at Blyvooruitzicht mine to the north of Savuka as well as at
Gold Fields’ Driefontein gold mine, but not at Savuka.
Exploration for these channels will be done by drilling from diamond drilling platforms developed at the end of each cross cut
at the CLR intersection. The series of exploration holes hopes to delineate the existence of a high-grade channel.
Three exploration LIB holes are planned to be drilled from 113 level towards the west. The targets will gain much needed
geological information on CLR to improve the geological confidence in the mine plan in that area. The holes will also be
extended to Middelvlei Reef.

South Africa – TauTona
Location
TauTona lies on the West Wits Line, just south of Carletonville in the North West Province, about 70km south-west of
Johannesburg. Mining at TauTona takes place at depths ranging from 2,000 to 3,640m. The mine has a three-shaft system
and is in the process of converting from longwall mining to scattered grid mining.
Geology
The CLR is a thin, on average 20cm thick, tabular, auriferous quartz pebble conglomerate formed near the base of the Central
Rand Group. The CLR has been divided into three facies units. Economically the most important is unit 1, which is present
as a sheet-like deposit over the whole mine, although reef development and grades tend to drop off very rapidly where unit 1
overlies unit 2. Unit 2 is a complex channel deposit that is only present along the eastern-most limit of current mining at
TauTona. The unit 2 CLR may be over 2m thick. Unit 3 is preserved below unit 1 in the southern parts of TauTona and is the
oldest of the CLR conglomerates.
Production levels on the VCR at TauTona are currently limited, contributing an average of 10% of total production volumes.
The VCR comprises a quartz pebble conglomerate (up to 2m thick) capping the top-most angular unconformity of the
Witwatersrand Supergroup. The topography of the VCR depositional area is uneven, and consists of a series of slopes and
horizontal terraces at different elevations.
The Exclusive Mineral Resource is dependant on mining strategy, but approximately 3.0Moz or 92% of the Exclusive Mineral
Resource is expected to be taken up in safety and remnant pillars ahead of current mining.
Exploration
Three projects will continue at TauTona during 2010; the CLR below 120 area, the area east of the Bank Dyke and the area
east of the mine. The aim is to increase the structural confidence and updating the facies model within these areas.

South Africa – Surface operations
The Metallurgy Department, as a business unit, produces gold in addition to that derived from the primary reef sources by
treating lower-grade surface sources of gold-bearing material. The strategy is the maximum utilisation of the treatment gap.
The surface source operations comprise the Vaal River and West Wits Surface sources operations.
Location
The Vaal River Surface operations are located immediately to the north and south of the Vaal River, close to the town of
Orkney, North West Province, South Africa. These operations comprise waste rock dumps and tailings dams resulting from
the mining and processing of the VR and VCR which were mined at the Vaal River underground mines in the Klerksdorp area.
The West Wits Surface operations are located on the West Wits Line, near the town of Carletonville, straddling the border
between the North West Province and Gauteng. These operations comprise waste rock dumps and tailings dams sourced
from the mining and processing of CLR and VCR which were mined at the West Wits underground mines in the
Carletonville/Fochville area.
Gold is mainly produced by the reclamation of waste rock dumps and the Sulphur Paydam (SPD).
The waste rock dumps have been built from waste rock mined from underground access development workings and hoisted,
transported and deposited via conveyor belt. The gold contained within these rock dumps was sourced from three areas:
minor reefs that were developed in order to access the primary reef;
reefs that were contained within small fault blocks that were exposed by off-reef development; and
cross-tramming of reef to the waste tips.
The tailings storage facilities store the residue product from the gold plants. These tailings were pumped in a slurry form onto
tailings dams and have been built up over a period of years.
Reclamation methodology
Bulldozers are used to create furrows through the waste rock dumps in order to mix rock from different parts of the waste
rock dumps that were deposited over different time periods. This is done to create a degree of homogenisation. The material
is then loaded onto rail hoppers and transported to the metallurgical plants.
The SPD is being reclaimed by means of remote controlled high-pressure hydraulic monitors. In order to facilitate blending of
low and higher grade material (necessitated by a definite grade gradient that exists from the bottom to the top of the tailings
dam), reclamation takes place in a three-bench, full-face operation. From the reclamation face, the slurry flows via trenches
to the SPD pump station, where oversized material is screened out and then pumped to the East Gold and Acid Flotation
(EGAF) plant for processing.

Regional overview
Navachab gold mine, AngloGold Ashanti’s sole operation in Namibia, is wholly owned by the Company.
Mineral Resource estimation
Mineral Resource estimation is performed using Datamine
®
software. Block dimensions of 25m x 25m x 5m are used as the
prototype model. Grade interpolation is done into these blocks using ordinary and ìndicator kriging methods. A geostatistical
technique called uniform conditioning is then used to estimate the proportion of economic ore that occur above the Mineral
Resource cut-off and this is reported according to the selective mining unit (SMU).

Namibia – Navachab
Location
Navachab gold mine is located 10km south-west of Karibib and 170km west-north-west of Windhoek, the capital of Namibia.
Navachab is mined as an open-pit mine. The current carbon-in-pulp (CIP) plant, with a production capacity of 120,000 tonnes
per month, includes mills, CIP and electro-winning facilities. In future, it is planned that a portion of the CIP feed will come
from a pre-concentration plant (DMS plant) with a 200t/h capacity.
Geology
The Navachab gold deposit is located in the Pan-African Damara Orogen and is hosted by greenschist-amphibolite facies
calc-silicates, marbles and volcanoclastic rocks. The rocks have been intruded by granite, pegmatite and aplitic dykes and
have also been deformed into a series of alternating dome and basin-like structures.
The main mineralisation forms a sheet-like body which plunges at an angle of approximately 20° to the north-west. The
mineralisation is predominantly hosted in a sheeted quartz vein set (±60%) and a replacement skarn (±40%).
The mineralisation in the main pit is hosted by a north-east to south-west striking metamorphosed sequence of calc-silicates,
marbles and volcanoclastic rocks that dip at 70° to the west. The gold is very fine-grained and associated with pyrrhotite and
minor amounts of pyrite, chalcopyrite, arsenopyrite, sphalerite, maldonite and bismuthinite. An estimated 90% of the gold
occurs as free gold and the remainder is present in minerals such as maldonite (Au
2
Bi). Silver is also present with a gold to
silver ratio of approximately 15 to 1.
Exploration
The exploration strategy at Navachab is to evaluate the shallow north pit 2 mineralisation (located near the main pit) down
plunge to 250m below surface. Drilling during the year has confirmed the down plunge extension of this ore shoot with
intersection ranging from 1.5 to 2.5g/t over 15 to 20m. This near surface mineralisation assists in unlocking deeper
hangingwall and footwall mineralisation for further exploitation to 350m below surface. Drilling during the next five years will
focus on growing the Mineral Resource base by 2Moz and increasing the confidence level of the mineralisation at Navachab.
Exploration of the satellite deposits will continue to identify near-surface, high-grade “Grid A” type mineralisation to displace
low-grade ounces during stripping of the main orebody extensions. Current satellite target areas are Anomaly 16, Gecko,
Steenbok, Starling and Klipspringer.
Projects
Exploration of the Gecko target has produced a shallow, high-grade Mineral Resource of 0.05Moz. This mineralisation can be
used to supplement the low production years. Exploration of Anomaly 16 target, which is approximately 7km from the plant,
has produced a lower-grade Mineral Resource of approximately 0.135Moz with the potential to grow significantly.

The main pit contains the largest portion (1.88Moz) of the Exclusive Mineral Resource. Of this, approximate 0.75Moz are in a
conceptual pit plan and further optimisation is continuing to bring this Exclusive Mineral Resource to account. Approximately
0.11Moz of the Exclusive Mineral Resource are hosted in the marginal ore stockpiles at a grade of 0.53g/t and the intention
is to test this for economic viability through pre-concentration during 2010.
The remainder of the Exclusive Mineral Resource is from Anomaly 16 (0.079Moz), Gecko (0.03Moz) and Grid A (0.002Moz).

Regional overview
AngloGold Ashanti has seven mining operations in its Continental Africa region:
Iduapriem and Obuasi in Ghana
Siguiri in Guinea
Morila, Sadiola and Yatela in Mali
Geita in Tanzania
Combined production from these operations declined by 3% to 1.52Moz of gold in 2009, equivalent to 33% of group
production. In addition, AngloGold Ashanti has an active greenfields exploration programme in the Democratic Republic of the
Congo (DRC), with Mongbwalu currently undergoing a pre-feasibility study, whilst the Kibali joint venture with Randgold
Resources and the DRC government is in the process of optimising the feasibility study. This is in addition to the brownfields
exploration being conducted in and around its existing operations.
The Mineral Resource in Continental Africa, attributable to AngloGold Ashanti, totalled 67.38Moz at year-end, including an
attributable Ore Reserve of 26.14Moz.

Democratic Republic of the Congo (DRC)
Regional overview
AngloGold Ashanti has two advanced projects in the DRC, Kibali and Mongbwalu.
Kibali
On 15 October 2009 Randgold acquired a 50% indirect interest in Moto Goldmines Ltd through a joint venture with AngloGold
Ashanti. On 21 December 2009, Randgold and AngloGold increased their joint venture interest to 90%, whilst OKIMO retained
a 10% holding.
The project is a joint development between three separate groups:
AngloGold Ashanti;
Randgold Resources Limited, who is the operator, an African-focused gold mining and exploration business with primary
listings on the London Stock Exchange and Nasdaq; and
L’Office des Mines d'Or de Kilo-Moto (OKIMO), the state-owned company.
The consolidated lease is made up of 10 mining concessions.
Mongbwalu
The Mongbwalu Project is one of AngloGold Ashanti’s most important exploration projects and is situated within the
10,000km
2
covered by Concession 40 in the Ituri Province of north-eastern DRC. Concession 40 has a rich history of gold
occurrences and cover the entire Kilo Archaean granite-greenstone belt that extends approximately 850km west-northwest
of Lake Albert. The concession is held in a joint venture between AngloGold Ashanti Kilo (AGAK) and OKIMO, a governmental
body which currently holds a 13.8% non-contributory share. AGAK is 86.2% owned by AngloGold Ashanti Limited.
The area around the old Adidi mine will undergo a feasibility study as part of the agreement with the DRC government.

Continental Africa – DRC – Kibali
P

DRC – Kibali
Location
The Kibali gold project is located in the north-eastern part of the DRC near the international borders with Uganda and Sudan.
The 1,841km
2
project area is centrally located around the village of Doko, approximately 180km by road from Arua on the
Ugandan border and immediately north of the town of Watsa. The district capital of Watsa lies about 9km to the south of the
project, which is situated just north of the Kibali River on the road to Faradje and the Sudan. The town of Bunia, which is the
United Nations controlled entry point to north-eastern DRC, lies about 200km to the south of the project.
Geology
The project is located within the Moto greenstone belt, which is comprised of the Archaean Kibalian volcano-sedimentary
rocks and ironstone-chert horizons that have been metamorphosed to greenschist facies. It is cut by regional-scale north,
east, north-east and north-west trending faults and is bounded to the north by the Middle Archaean West Nile granite-gneiss
complex and cut to the south by the Upper Zaire granitic complex.
The stratigraphy consists of a volcano-sedimentary sequence comprising fine-grained sedimentary rocks, several varieties of
pyroclastic rocks, basaltic rocks, mafic-intermediate intrusions (dykes and sills) and intermediate-felsic intrusive rocks (stocks,
dykes and sills). The sequence is variably altered from slight to intense such that in some cases the original rock is
unrecognisable.
Exploration
Exploration focused on the delineation drilling of the Mineral Resource at the main KCD deposit. The structural and lithological
controls of the KCD deposit were reviewed as well as a possible lateral link with the Gorungwa deposit.
A robust structural-alteration model is in place:
1.
Mineralisation is controlled by zones of texturally destructive albite-carbonate-silica alteration (syn D1) along faults with a
similar orientation as S1. S1 is a regional shear fabric and in general strike north-west with a low dip to the north-east.
D1 is interpreted as shortening from the north-east, West Nile block over the basalt-volcanoclastic sequences, causing
south-west verging folds and thrusts.
2.
Gold mineralisation was introduced late D1 to D2 due to preferential fracturing of the albite-carbonate-silica alteration
zones. S2 is an axial plane cleavage and in general strikes north-east with a moderate to steep dip north-west, explaining
the north-east trending mineralised corridors. D2 also causes the folding of S1, creating double plunging folds, as observed
in KCD mineralised zones. A prominent stretch lineation, L1, was also observed. It has in general a shallow plunge towards
north-east.
3.
Post-mineralisation D3 produced a pervasive crenulation cleavage that in general strikes south-east with a low dip south-west.
Mineral Resource and Ore Reserve update
Cube Consulting completed an updated Mineral Resource estimation on KCD based on all drilling completed to August 2009.
New Mineral Resource numbers were generated and are reflected overleaf.

Main changes in the Mineral Resource from the previous declaration include:
The open-pit Mineral Resource has been constrained within the US$1,000/oz Whittle pit shell at a 0.5g/t gold cut-off.
In the case of the KCD deposit, the underground Mineral Resource is reported as that material between the base of the pit
to underground interface (5,685m RL), at a 2g/t gold cutoff.
The net result is a slightly lower total Mineral Resource than previously reported but a significant increase in the Indicated
Mineral Resource, with 70% of the total Mineral Resource now being classified as an Indicated Mineral Resource.
Main changes in the Ore Reserve from the previous declaration include:
Cube Consulting completed the open-pit Ore Reserve estimation from the updated Mineral Resource numbers, while SRK
Consulting completed an update of the underground Ore Reserve based on a $700 gold price. New Ore Reserve numbers
are presented below and reflect a significant increase in the underground Ore Reserve to almost 6Moz, bringing the total
Ore Reserve number to 9.2Moz, a 67% increase from the previous declaration.

DRC – Mongbwalu
Location
The Mongbwalu project is located in Concession 40 (C40) in the north-east of the DRC. It is situated next to the village of
Mongbwalu which is 84km north-west of the regional town of Bunia and 320km north-west of Kampala in neighbouring
Uganda. An area of 7,443km
2
within C40 is held in a joint venture under an ammodiation agreement between AngloGold
Ashanti and OKIMO, which currently holds a 13.8% non-contributory share. The joint venture company is called Ashanti
Goldfields Kilo Ltd (AGK). The DRC Minerals Review Commission and negotiations with the Government led to an agreement
to transfer the mining rights of an area of 6,007km
2
in C40 from OKIMO to the joint venture. The area to be transferred contains
approximately 19 permits. The process of transferring the mining rights from OKIMO to AGK is expected to be concluded
early in 2010. As one of the conditions of the title transfer, AGK will be required to complete a feasibility study within
12 months.
Geology
Granitoids are the predominant rock type within the Kilo granite-greenstone belt. The granitoids contain rafts of Kibalian
amphibolites and talc carbonate schists that have been intruded by diorite-tonalite-granodiorite assemblages. The
Mongbwalu mineralisation is hosted in multiple, shallow dipping mylonite bodies that average 25m in width. Within the
mylonite zones, the gold is primarily concentrated in boudinaged quartz veins that appear to be orientated sub-parallel to the
mylonite zones and their immediate wall-rock. The alteration assemblage consists of chlorite-biotite-quartz-sericite and
mineralisation occurs in a pyrite-pyrrhotite assemblage (<2%) and in pyrite-pyrrhotite (<2%) and as free gold.
The easterly dipping mylonite zones are continuous throughout the area drilled, with the most prospective zone located close
to the old Adidi underground mine. Two north-south trending faults have offset the mineralisation and kept the mineralisation
within 300m of the surface. The mylonite can be traced along a strike length of approximately 8km through historical mining,
artisinal mining and recent geological mapping.
Exploration
All field-based exploration activities over the licence area were suspended in November 2008 following the deteriorating
security situation which led to the precautionary withdrawal of most non-essential staff from the concession. Interpretation
work of existing data continued through 2009, and field activities recommenced in November 2009, including drilling in the
Mongbwalu area.
The majority of AGK’s exploration activities in C40 have focused on the delineation of the Mineral Resource in the vicinity of
the abandoned underground Adidi-Kanga and Nzebi gold mines.
The most prospective parts of the greenstone belt have been covered by a total of 5,575km
2
of airborne magnetic and
radiometric surveys and a detailed geological interpretation map has been completed of the same area. The numerous gold
occurrences throughout the concession occur in geologically distinct belts and can efficiently be explored with soil sampling
programs. The stripped regolith profile makes soil sampling a very effective sampling strategy. Three fly camps have been
established as bases for the regional field work.

Project
At the conclusion of the joint venture agreement negotiations, a detailed feasibility study will commence on the Mongbwalu
Mineral Resource. This 12-month study is aimed at developing a financially viable mine that has the potential to generate rapid
cash flows with a payback period of less than seven years. The mining operations are planned to feed a plant with
approximately 60,000tpm. A high level conceptual study of the various mining options shows an underground mining method
will generate the highest cash flow.
The feasibility study will be focused on developing an underground mine centred around the old Adidi underground workings
that will potentially use some of the existing development to access ore as soon as possible.
Mineral Resource Estimation
AGK began drill testing of the Mineral Resource potential of the Mongbwalu area in mid-2005 and by the end of 2006, the
broader Mongbwalu area (Nzebi-Adidi-Kanga-Pluto) had been diamond drilled on a 200m x 200m grid. The programme
covered an area 2.2 by 2.7km centred over the southern part of the old Adidi mine.
From this drilling, distinct zones with potentially economic grades of gold in quartz-veins and mylonite were delineated. Infill
RC and DD on 50m x 50m centres was undertaken during 2007 to cover the areas of maximum potential hosting near-surface
open pit or shallow underground extractable mineralisation. The aim was to define an initial Inferred Mineral Resource by the
end of 2007. Data obtained from a total of 87,933m of drilling was used for Mineral Resource modelling and estimation which
was completed in late 2007. Resource drilling continued into 2008 with a single diamond rig and 8,824m of additional drilling
was completed.
In September 2009 a second Mineral Resource estimation was completed. The principal Mongbwalu mylonite horizons and
other important geological units defined by drillhole logging and interpretation were modelled using conventional 3D
wireframing techniques. To define the Inferred Mineral Resource, ore envelopes were created using a combination of grades
greater than 3.0g/t and the presence of quartz veining. Following geostatistical evaluation of the drillhole assay database, gold
grades were interpolated into a 3D block-model incorporating the principal geological units and ore envelopes using ordinary
kriging to define the Inferred Mineral Resource.
Initial scoping level mining, metallurgical, geotechnical, hydrogeological, environmental, socio-political and infrastructural
engineering studies were undertaken in parallel with the drilling to support the Mineral Resource estimate.

Ghana
Regional overview
AngloGold Ashanti has two mines in Ghana: Obuasi, which has both surface and underground operations and Iduapriem, an
open-pit mine. Obuasi and Iduapriem are both wholly owned by AngloGold Ashanti. Obuasi is located in the Ashanti region
of southern Ghana, approximately 80km south of Kumasi. It is primarily an underground mine operating at depths of up to
1,500m with a continuous history of mining dating back to the 1890s.
The orebody consists of two main ore types, firstly, quartz veining with non-refractory free gold and secondly, a sulphide-
hosted mineralisation style generally associated with arsenopyrite which is refractory. Three main structural trends control the
gold mineralisation within a 9km long continuous zone which remains open at depth. The Obuasi orebody is considered one
of the classic Birimian hosted orebodies.
At Iduapriem, situated in the western region of Ghana, some 70km north of the coastal city of Takoradi and 10km
south-west of Tarkwa, the gold mineralisation is hosted by the Proterozoic Banket Series, a conglomerate sequence of the
Tarkwaian System.
Mineral Resource estimation
Mineral Resource estimates are derived from interpretations of information about the location, shape, continuity and grade of
the individual orebodies.
The underground Mineral Resource at Obuasi is estimated using block models within the delineated mineralised ore zones.
The geological interpretation is based on diamond drill and cross-cut sampling information. A prototype block model of
20m x 5m x 15m representing the minimum mining unit was used and estimates are based on ordinary kriging.
Although no open-pit mining has taken place at Obuasi since 2005, three pits still contain a Mineral Resource. The open pit
Mineral Resource at Obuasi and Iduapriem was estimated using 3D computer block models constructed using the Datamine
®
software. Geological interpretation was based on trench and RC and/or DD data. A prototype block model of 30m x 30m x 10m
was used by the geological model and ordinary kriging as the primary estimation methodology.
Surface stockpiles volumes are based on surveyed figures and grades based on historical sampling. Tailings are part of the
Mineral Resource with tonnes and grades based on combinations of 3D block models of some dams and historical
metallurgical discharge data.
Ore Reserve estimation
The 3D Mineral Resource models are used as the basis for the Ore Reserve. An ore envelope is developed using the Mineral
Resource block model, geological information and the relevant cut-off grade, which is then used for mine design. Datamine
®
software called Mineral Resource Optimizer is used to generate the ore envelope. An appropriate mining layout is designed
that incorporates mining extraction losses, dilution factors and MCF.

Ghana – Iduapriem
Location
Iduapriem is located in the western region of Ghana, some 85km north of the coastal city of Takoradi, and approximately 8km
south-west of Tarkwa. Iduapriem is an open-pit mine which began mining operations in 1992. Its processing facilities include
a 4.4Mt per annum CIP plant with a gravity circuit that recovers about 30% total gold.
Geology
Iduapriem is located within the Tarkwaian Group and forms part of the West Africa Craton which is covered to a large extent
by metavolcanics and metasediments of the Birimian Supergroup. In Ghana, the Birimian terrane consists of north-east to
south-west trending volcanic belts separated by basins and the Tarkwa Group was deposited in these basins as shallow water
deltaic sedimentation. The gold mineralisation is contained in the Proterozoic Banket Series conglomerates.
The Banket Reef Zone comprises a sequence of individual beds of quartz pebble conglomerates (Banket beds), breccia
conglomerates, meta-sandstones (also called quartzites) and grits.The outcropping Banket Series in the mine area form
prominent arcuate ridges extending southwards from Tarkwa, westwards through Iduapriem and northwards towards
Teberebie.
All known gold mineralisation within the Banket Series is associated with the conglomerates and is found within the matrix
that binds the pebbles together. Gold content is a function of the size and amount (packing) of quartz pebbles present within
a conglomeratic unit. At Iduapriem, the gold mineralisation is unrelated to metamorphic or hydrothermal alteration events and
the gold is particulate and free milling. Mineralogical studies indicate that the grain size of native gold particles ranges between
2 and 500 microns (0.002 to 0.5mm) and averages 130 microns (0.13mm). Sulphide mineralisation is present only at trace
levels and is not associated with the gold.
Exploration
The leases of the mine have been extensively explored for their near surface Mineral Resource. However, limited work has
been done to assess the underground potential of these lease holdings. Hence, the opportunity to increase the Mineral
Resource of the mine lies predominantly in the under-explored underground area. Studies are currently underway to determine
if an economic Mineral Resource to support an underground mining proposition could be defined.

Ghana – Obuasi
Location
The Obuasi mine is located in the Ashanti region of Ghana, some 80km south of Kumasi. It is an underground mine extending
over 9km on strike and mining to a depth of 1,500m below surface. Large-scale open-pit mining took place between the years
1990 and 2000 and the contribution from open-pit mining is currently less than 1% of annual production. There are two active
treatment plants: the sulphide treatment plant to process underground ore and the tailings treatment plant to handle tailings
reclamation operations.
Geology
The gold deposits at Obuasi are part of a prominent gold belt of Proterozoic (Birimian) volcano-sedimentary and igneous
formations. These deposits extend for a distance of approximately 300km, in a north-east/south-west trend, in south-western
Ghana. Obuasi gold mineralisation is shear-zone-related and there are three main structural trends within the Obuasi
concession; namely the Main trend, the Gyabunsu trend and the Binsere trend. The underground mine is situated on the Main
trend which is a graphite-chlorite-sericite fault zone associated with silica, carbonate and sulphide hydrothermal alteration.
Deformation of the main shear resulted in an anastomosing structural pattern of secondary mineralised shears with pinch and
swell structures. This is more evident where more resistant metavolcanics occur as lenses within the system.
Two main ore types are mined, namely quartz veins and sulphide ore. The quartz vein type consists mainly of quartz with free
gold in association with lesser amounts of various metal sulphides containing iron, zinc, lead and copper. This ore type is
generally non-refractory.
Sulphide ore is characterised by the inclusion of gold in the crystal structure of sulphide minerals. Higher gold grades tend to
be associated with finer grained arsenopyrite crystals. Other prominent minerals include quartz, chlorite and sericite. Sulphide
ore is generally refractory.

Exploration
Exploration on the Obuasi concession is currently limited to underground drilling to explore the Obuasi Deeps below 50 level
and southern extensions of the current mining areas above 50 level. Drilling from 50 level was suspended in July 2009 as a
result of torrential rain which flooded the level. Exploration activities will re-commence in early 2010.
Exploration drilling above 50 level recommenced in August 2009 and the first ore zone intersection is expected early in 2010.
Projects
Mining method
Obuasi has embarked on a conversion of mining method over the next two years from current transverse and longitudinal
open stoping, to a full longitudinal retreat method (LRM). The conversion will take place in mining blocks where it is suitable
to do so. In 2008, 20% of the mine was designed for LRM; in 2009 up to 70% above 50 level and 100% below 50 level had
been designed with the new method and 100% below 50 level. Stope production is scheduled to start in mid 2010.
The major advantage of this method is the up to 50% reduction in waste development; reducing capital expenditure along
with additional reef drive exposure.
The change in mining method has been coupled with the introduction of fully mechanised development from the second
quarter of 2010 with up to 65% of all development being mechanised by 2012.
Pompora reclamation project
The objective of the project is to construct a reclamation station and pipeline to enable the reclamation of Kokoteasua and
Pompora tailing storage facilities and pump the reclaimed material to the tailings treatment plant (TSP) to extract the gold. The
feasibility study is based on the utilisation of the TSP float circuit and redundant capacity in the Biox
©
and Biox
©
CIL circuit at
the sulphide treatment plant.
KMS 50-60 level mining block 11
The intention is to complete the feasibility for this project late in 2010. Initial development is scheduled for the first quarter of
2011. The project is designed to be fully LRM with 100% mechanised development. First gold from the project is scheduled
for 2013.

Exclusive Mineral Resource
The Obuasi Exclusive Mineral Resource is made up of Mineral Resource from underground, open pit and tailings. The bulk of
the Exclusive Mineral Resource (71%) is from underground and of this Mineral Resource, 52% is locked up in Mineral
Resource blocks and remnants in historical mined out areas in the north of the mine. This Mineral Resource cannot be
accessed due to old infrastructure. The remainder of the underground Exclusive Mineral Resource is mineable between
Mineral Resource and Ore Reserve cut-offs (11%), below 50 level (18%) and in areas where more investigation is required (6%).
Some of the Exclusive Mineral Resource will be brought into the Ore Reserve as mining development is put into place to
access these areas, and also as the economic criteria change.
Approximately 10% of the Exclusive Mineral Resource is from tailings and will be brought into the Ore Reserve as infrastructure
is developed and capacity is increased in the tailings treatment plant. Two of the tailings dams are also active and an Exclusive
Mineral Resource margin will be maintained.
None of the three open pits in the Mineral Resource is currently included in the Ore Reserve. This represents 4% of the
Exclusive Mineral Resource. To bring open pits into the Ore Reserve will require more geotechnical investigation, optimisation
and mine design.

Guinea
Regional overview
The Siguiri mine is AngloGold Ashanti’s only operation in the Republic of Guinea in West Africa. The mine is 85% owned by
AngloGold Ashanti and 15% by the government of Guinea. The mine is a conventional open-pit operation situated in the Siguiri
district in the north-east of the Republic of Guinea, West Africa. It lies about 850km from the capital city of Conakry. Gold-
bearing ore is mined from several pits and sent to a CIP plant.
The Siguiri orebody is hosted in Birimian aged rocks and characterised by wide zones of multiple narrow quartz veins hosting
gold mineralisation. The deposits have been influenced by a deep weathering profile, typically 50-80m below surface, resulting
in broad zones of low grade mineralisation easily amenable to bulk mining methods. Mining is presently focused on block 1,
which hosts the processing plant and mining operations, with ongoing exploration of blocks 2-4 expected to increase
significantly in line with the operations’ long term development plans so as to maximise the Mineral Resource potential.
Mineral Resource estimation
Mineral Resource definition drilling consists of air core (AC), reverse circulation (RC) and diamond drilling (DD) boreholes.
All available geological drillhole information is validated for usage in the models and the local geology of the orebody is used
to classify the drillhole information into appropriate geostatistical domains. Detailed statistical analyses are conducted on each
of these domains and this allows for the identification of high grade outliers. If these values are anomalous to the general
population characteristics then they are cut back to the appropriate upper limit of the population.
The Mineral Resource is estimated using 3D computer block models constructed in Datamine
®
software. Geological
interpretation is based on geological borehole data. A prototype block model ranging from 10m x 10m x 2.5m to 50m x 25m
x 6m block sizes, depending on the shape of the orebody and drilling density, is used within the geological model outlines.
Ordinary and indicator kriging are used to estimate gold grades and a limiting pit shell at $1,025/oz is used to quantify the
total Mineral Resource.

Ore Reserve estimation
The Mineral Resource models for each pit are depleted to the mining surfaces. Costs are assigned on a pit-by-pit basis
reflecting the current existing cost structure of the operation. The relevant dilution and ore loss factors are applied and the
optimisation is done in Whittle
®
software. The relevant metallurgical recoveries, geotechnical parameters, cut-off grades and
economics are applied to generate the final Ore Reserve.

Guinea – Siguiri
Location
Société Ashanti Goldfields De Guinée
Siguiri gold mine is situated in the Siguiri district in the north-east of the Republic of Guinea, West Africa, about 850km from
the capital city of Conakry. The mining concession consists of four blocks totalling 1,494.58km
2
. It is a multi open-pit oxide
gold mining operation. The current LOM plan entails the mining of eleven individual pits, several of which are multi-stage. All
ore and waste is mined by a mining contractor in a conventional open-pit mining operation. Processing is done via a CIP plant.
Geology
This concession is dominated by Neoproterozoic Birimian rocks which consist of turbidite facies sequences and lesser
volcanoclastic sequences. The mineralisation is structurally controlled and occurs either as sheeted veins or within shear
zones. There are two main types of oxide mineralisation in the Siguiri basin: elluvial- or alluvial-hosted laterite mineralisation
and primary quartz-vein-related or shear hosted mineralisation. The laterite mineralisation occurs as aprons of colluvial or as
palaeo-channels of alluvial lateritic gravel adjacent to, and immediately above, the in situ vein-related or shear zone
mineralisation. The in-situ mineralisation can occur as either sheeted veins or associated with shear zones, with the best
mineralisation often occurring at the intersection of the two.
The shear hosted style appears to be a slightly older event related to the development of a number of north-south striking
shear zones that may cut different lithologies. This phase of mineralisation is usually associated with silicification, brecciation
and quartz-albite-pyrite veining, with magnetite being present at some localities. The vein-related mineralisation occurs as
north-east to south-east to east-west striking, discontinuous sheeted veins. The better mineralised areas are associated with
vein stockworks that occur preferentially in the coarser, brittle siltstones and sandstones. The sheeted veins appear to be
related to a younger folding event and appear to be developed on fold axial planes. Mineralisation is associated with white
quartz veins, with grey selvages and scattered large arsenopyrite crystals proximal to these veins. Mineralisation at Siguiri has
been deeply weathered to an average vertical depth of 100m, and the mineralised saprolite provides the primary oxide
feedstock for the CIP plant. Fresh hard mineralisation is not processed in the current plant. The practice at Siguiri was to blend
the laterite and saprolite ore types and to process these using the heap-leach method. With the percentage of available laterite
ore decreasing, however, a CIP plant was brought on stream during 2005 to treat predominantly saprolite oxide ore.
The Siguiri mineralisation is characterised by coarse gold with low average grade and highly skewed distributions. This is the
main geological feature taken into account during data collection and estimation.
Exploration
The primary objective of the exploration initiative at Siguiri is to discover or upgrade prospective areas, enhancing the value
of the concession. Exploration is focused on finding and upgrading oxide style mineralisation in the saprolite, using drillhole
sampling, geophysics, and soil geochemistry in the context of the regional and pit-scale geological models. Almost 190,000m
were drilled during the year, and consisted of 156,700m brownfield exploration, 21,195m sterilisation, 7,032m Sintroko test
work and 5,071m for metallurgical testing.
The areas around the current pits were the focus of this year’s drilling, investigating potential extensions to the current pits.
The principal targets that were explored include Sintroko South and West, Kosise South, Kami South, Kami Saddle, Kozan
Northwest, Toubani Extension, Eureka East and Komatiguia. Extension drilling was undertaken at Sintroko South and to the
north-west of Seguélén pits. The Seguélén north-west extension drilling (Komatiguia project) was done after completion of a
detailed gravity survey and the identification of a geochemical soil anomaly. The fresh rock potential below a number of pits

was also investigated, with particular emphasis on the Kami, Sintroko and Bidini pits. Metallurgical drilling was completed
under these pits with the aim of obtaining samples to be used for gold deportment and extraction studies. One gravity survey
was completed in the Kintinian area and geochemical sampling of block 1 continued through the year with approximately 70%
of block 1 being sampled on a 200m x 50m grid by year end.

Mineral Resource
Mineral Resource growth during the year was mainly due to exploration infill drilling and updated Mineral Resource modelling
in which the main mining area, consisting of 12 deposits, was modelled in an integrated approach. Previously the deposits
were modelled, optimised, designed and scheduled independently. The impact of the integrated approach is that some of the
individual pits have merged, highlighting opportunities between the current pits.
Seguélén
The Mineral Resource as published for Seguélén does not reflect the full potential of the deposit. An additional 10Mt grading
at 1.2g/t (380,000oz) have been delineated by a 50m x 50m drill pattern. This mineralisation is currently not accessible due
to its proximity to the Kintinian village and hence cannot be considered, at this stage, to have a reasonable and realistic
prospect for eventual economic extraction. Based on mineralised trends there may be further untested potential beneath the
Kintinian village. Negotiations with the local authorities are underway in an effort to secure access.
Sintroko
A bulk sampling project was initiated during the year at the Sintroko Pit after discrepancies were noted in the initial
reconciliations between grade control and the Mineral Resource model. The project involved drilling a volume of ground with
both exploration and grade control drill rigs and sampling protocols. The material was then mined and processed. The
preliminary results show good correlation between the new exploration and grade control drilling. The project is still in progress
with results expected during the first quarter of 2010. The project is expected to provide valuable insight into maximising the
overall value of Siguiri.

Exclusive Mineral Resource
The Exclusive Mineral Resource represents the future potential at Siguiri and comes from three areas:
material that is economic at the Mineral Resource gold price of US$1,025 per ounce, but not at the Ore Reserve price of
US$800 per ounce (67% of the Exclusive Mineral Resource);
new deposits that are currently at the Inferred level of confidence. These areas will be in-fill drilled in the future (26% of the
Exclusive Mineral Resource); and
the Inferred Mineral Resource within the current pit designs (7% of the Exclusive Mineral Resource).
Inferred Mineral Resource in business plan
The Inferred Mineral Resource is used in the pit optimisation process if its total percentage amounts to 10% or less of the total
Ore Reserve. If the Inferred Mineral Resource was greater than 15%, the optimisation was redone excluding the Inferred
resultant ounces. The Inferred Mineral Resource within an optimised shell and subsequent design was used for scheduling.
The final schedule included 283,364oz of Inferred Mineral Resource in the final designs, which represents 7% of the scheduled
ounces.

Mineral Resource estimation
The Mineral Resource is taken as the material that falls within the $1,025/oz economic shell optimised for each individual
deposit. A 3D surface is generated to create the outline of the geological model. This model is then used as a prototype model
to estimate grades. Block sizes are between 25m x 25m x 10m and 30m x 30m x 10m (X Y Z) and where appropriate,
selective sub-celling is used for definition on the geological and mineralisation boundaries. All the deposits have kriged block
models and where appropriate, a geostatistical technique called uniform conditioning is used to estimate the proportion of
economic ore that occurs above the cut-off and this is reported according to the dimensions of the practical mining unit.

Ore Reserve estimation
The Mineral Resource models are used as the basis for the Ore Reserve. Pit optimisation is done using Whittle
®
software.
The typical Whittle approach for a mill-constrained operation is followed. Optimisations are run on Measured and Indicated
Mineral Resource and Measured, Indicated and Inferred Mineral Resource. All appropriate costs, metallurgical recovery
factors and geotechnical parameters are applied to generate the final Ore Reserve.

Mali – Morila
Location
The Morila mine is situated some 280km by road south-east of Bamako, the capital city of Mali. The mine is operated by
Morila SA, a joint venture company incorporating Randgold Resources Ltd (40%), Anglogold Ashanti Ltd (40%), and the
Government of Mali (20%). Randgold Resources took over the operation of Morila mine from Anglogold Ashanti Ltd in
February 2008.
Mining
The Morila open-pit activities were successfully completed in April 2009. Consequently the main mining activity for the rest of
the mine life will be rehandling already mined stockpiles at a rate of 4.2Mtpa using a core and backup fleet comprising two
hydraulic excavators, two CAT 990 front-end loaders and seven Caterpillar 777 dump trucks.
Geology
The Morila orebody is located predominantly in metasediments within a broad north-north-west-trending corridor of shearing.
This shear zone has both near vertical and flat lying components. It is interpreted as being a second order shear off the main
Banafin shear, approximately 25km to the east. The Doubalakoro granite pluton bounds the sediments to the west and the
Massigui granite to the east. The deposit occurs within a sequence of amphibolites facies metamorphosed Birimian meta-
sediments. Gold mineralisation is associated with silica feldspar alteration and the sulphide minerals arsenopyrite, pyrrhotite,
and pyrite (with minor chalcopyrite).
Processing
Ore is processed at a rate of 4.2Mtpa via a conventional CIL plant after passing through primary and secondary crushing
processes followed by further comminution via a semi-autogenous grinding (SAG) mill and ball mill. After milling and
classification, the slurried ore passes through the cyanide leach circuit for gold extraction after which the leached ore is
pumped and deposited into the tailings storage facility (TSF). Supernatant water from the TSF is reclaimed and collected in
the return water dam before being returned to the mill for re-use.

Mali – Sadiola
Location
Sadiola is situated in the north-west of Mali, 77km to the south of the regional capital of Kayes. The mining operations take
place in five open pits, the Sadiola main pit and four satellite pits, namely FE3 pits 1 to 3 and pit FE4.
Ore is treated in a 4.8Mtpa CIP processing plant. The plant was originally designed to treat soft oxide ore, but has been
progressively adapted to receive soft sulphide ores and even some types of hard oxide ores.
The down dip extension of the mineralisation mined in the Sadiola main pit has been named the Deep Sulphides Project (DSP),
in which the gold ore occurs in the underlying fresh rock. A full feasibility study of the DSP is scheduled for completion in 2010.
The project may substantially extend the life of Sadiola’s operations and leverage exploration efforts and further discoveries of
hard-rock gold deposits in the district.
Geology
The Sadiola deposits are located within the Malian portion of the Keniéba-Kedougou window, a major early Proterozoic-
Birimian outlier along the north-east margin of the Kenema-Man shield. The deposits are confined to the north portion of
the window.
The Sadiola Hill deposit is underlain by the north-trending Sadiola Fracture Zone (SFZ), over a drilled strike length of
approximately 2,500m, running along the contact of marbles and greywackes and intruded by bodies of diorite and
quart-feldspar porphyries. North-east trending structures, often intruded by quartz-feldspar porphyries, extending to the east
of the SFZ, also carry gold. The mineralised zones have been intensely weathered to a maximum depth of 200m.
The Sadiola Hill deposit originally consisted of two zones, an upper oxidised cap and an underlying sulphide zone. From 1996
until 2002, shallow saprolite oxide ore was the primary ore source. Since 2002, the deeper saprolitic sulphide ore has been
mined, progressively replacing the depleted oxide Ore Reserve.
The satellite pits are located to south-east of the Sadiola Hill mine and are underlain by different lithologies. The mineralised
zones straddle the contact between marbles to the west and carbon-rich pelites to the east, following a north-north-west-
trend in the FE3 pits 1 and 2, north-north-east at pit 3, and a north-east-strike in FE4 pit, due to regional folding. Gold
mineralisation is mostly associated with lens-shaped breccia zones running broadly parallel to the enclosing metasediments
and folded accordingly.
At this stage all the gold is recovered from mostly soft, oxidised ore from the satellite pits. Some gold-rich, hard oxide nodes
have been also treated in the Sadiola plant, after first stage crushing.

Exclusive Mineral Resource
The Exclusive Mineral Resource for the Sadiola pits is the Mineral Resource that is outside the current Ore Reserve designs
but inside the Mineral Resource shells. Any Inferred Mineral Resource within the design shells is also reported in the Exclusive
Mineral Resource. Unless the gold price increases and the costs are favourable, only the Inferred Mineral Resource portion of
the Mineral Resource within the LOM shell will be converted to the Ore Reserve through grade control drilling.
FE3 has Inferred Mineral Resource in the published Mineral Resource and therefore the only possibility for converting the
Exclusive Mineral Resource to the Proved Ore Reserve is through favourable gold price and cost changes. The FE3 pit has
27% of Inferred Mineral Resource within the design shell and FE4 has 86%.
The FE3 Inferred Mineral Resource can be upgraded into Ore Reserve by normal grade control drilling. For FE4, infill drilling
has been completed and the FE4 Mineral Resource model will be revised in the first quarter of 2010. Updating the models for
FE4 may lead to an increase in Ore Reserve. For the Main Pit, the feasibility study of the DSP will be completed in the
4th quarter of 2010.

Inferred Mineral Resource in pit optimisation
The Inferred Mineral Resource was used in the pit optimisation process and 0.95Moz are present in the optimised pit, of which
0.23Moz are included in the final production schedule. This includes the DSP and satellite pits.
Exploration
The philosophy underpinning the future programme is that at mine closure, the full potential of the two leases will have
been exploited.
The exploration strategy is twofold:
there was a narrow window of opportunity of 18 months for a focused exploration programme on oxide material from
March 2009 to July 2010 to fit into the current LOM estimate; and
testing sulphide targets as a complementary strategy, aimed at adding soft sulphide ounces to the Sadiola plant and hard
sulphide Mineral Resource to the DSP.
Projects:
There are currently two projects under consideration:
The DSP is the most advanced, with a board-approved feasibility study due for completion in September 2010.
Low-grade project: if costs can be decreased by up to 20%, it will allow the Sadiola plant to treat lower grade ore, with the
result that the ore can be mined at a lower cut-off with a higher throughput.

Mali – Yatela
Location
Yatela mine is situated some 25km north of Sadiola and approximately 50km south-west of Kayes. The Yatela operation is
currently mining from two open pits, the Yatela main pit and the satellite Alamoutala pits. The Yatela main pit is currently mining
Pushback 7, toward the western end of the pit and the mine is approaching the end of its life.
Ore is processed through a 3.0Mtpa heap leach plant, commissioned in 2000. The pregnant liquor pond for gold recovery
uses the carbon in solution process. Loaded carbon is sent to Sadiola for elution, regeneration, electro-winning and smelting.
Geology
The Yatela deposit is located within the Malian portion of the Keniéba-Kedougou window, a major Early Proterozoic-Birimian
outlier along the north-east margin of the Kenema-Man shield.
The Yatela deposit is located in the north of the window and is hosted by sediments of the Kofi Formation, which have
been intruded by numerous felsic intrusives. The sediments consist of fine-grained greywacke, pelites that are locally carbon-rich,
and impure limestones with minor tuffs and acid volcanics.
The primary gold mineralisation at Yatela is associated with a sheared contact between predominantly dolomitic rocks of the
Kofi Formation to the west and a large, weakly mineralised, dioritic intrusion to the east. This primary mineralisation was
concentrated to economic grades through dissolution of carbonate-rich rocks by supergene processes. Karsting of carbonate
rocks has resulted in the development of deep, coalescent pot holes, collectively named the Yatela Basin, which were
gradually filled by sandstones and conglomerates during peneplanation of the Proterozoic rocks. The chaotic collapse during
karsting, coupled with the infill sediments resulted in the orebody being hosted in a melange-type of rocks made up of
sedimentary rocks and dissolution residues. Gold is disseminated in the unconsolidated ferruginous, sandy-clayed layer that
lines the bottom and walls of a deep trough with steep margins. The ore zone dips steeply on the west wall and more gently
to the west on the east wall, following a keel-like geometry with tight closure towards the south. The supergene enrichment
of low-grade primary gold mineralisation, associated with the karst forming process, is the most important geological feature
to the economics of the Yatela deposit.
In the Alamoutala pits, the gold mineralisation is mined from the saprolitised marbles and karstic rocks in the south, and from
weathered Birimian rocks to the north. The Alamoutala area is underlain by north-trending Birimian clastic metasediments and
calcitic marbles, which are intruded by a coarse grained granodiorite body. Gold mineralisation is found along an intermittently
sheared and fractured contact, named the Alamoutala Fracture Zone, between the metaclastics and the carbonate units.
These rocks have locally been strongly biotite- and feldspar-altered. High-grade gold mineralisation is also hosted in
magnetite-bearing, skarn-like calc-silicate rocks along the contact with the granodiorite intrusive.
Exploration
The key philosophy underpinning the programme is one of ‘no regrets’; at mine closure the full potential of the lease will have
had an opportunity to have been exploited. The exploration strategy has a narrow window of opportunity due to the limited
life of mine. An 18-month focused exploration programme, which started in March 2009, is currently underway, with the aim of:
focusing on oxide targets;
drill testing the gravity lows on top of marbles for Yatela-type deposits; and
testing sulphide targets as a complementary strategy, aimed at adding soft sulphide ounces to the Sadiola plant and hard
sulphide resources to the DSP.

Projects
The ongoing exploration programme as well as possible partnerships with nearby lease holders may result in additional
Ore Reserves.
In August 2009, mining in the Yatela pit was suspended for a month due to geotechnical issues. In light of the mining
suspension, the economics of reopening the Alamoutala pit were reviewed. The Alamoutala $880/oz pit shell showed a
profitable return, and mining began during August. Additional drilling within and adjacent to the Alamoutala pit highlighted a
likely area south of the existing pit to continue mining to January 2010.
Additional drilling both within and south-east of the existing Yatela pit shows similar promise. Both areas were evaluated during
December and final decisions will be made in 2010.

Exclusive Mineral Resource
The Exclusive Mineral Resource for Yatela is that Mineral Resource that falls outside the current LOM but inside the Mineral
Resource shells for the Yatela main and Alamoutala pits. Any Inferred Mineral Resource within the LOM shell is also considered
Exclusive. Currently, only the Inferred Mineral Resource within the LOM shell at the Yatela main pit is convertible to Ore Reserve
and this will be done through grade control drilling. In addition, the Yatela main pit will also be optimised in order to ensure
that all recoverable material is mined before the envisaged closure.
The Alamoutala Mineral Resource was depleted to the LOM shell in 2005. However, considering the increase in the gold price
since then, there is a realistic possibility that additional mining will be conducted here in 2010.

Geita is the largest of AngloGold Ashanti’s seven open-pit mines in Africa. Prior to April 2004, Geita was managed under the
joint venture agreement between Ashanti and AngloGold. Since the merger of the two companies, Geita is now a wholly-
owned subsidiary.
Mineral Resource estimation
As with any estimation techniques the results are very dependent upon the data quality and availability. The geological model
is a critical input to the Mineral Resource estimation process. The orebody boundaries for the individual deposits are defined
from the detailed logging of all geological boreholes and after validation this information is used to create a three dimensional
model. This model is subsequently populated with an appropriately dimensioned block model. The size of this block model is
determined by analysing different block sizes in relation to the variance of the blocks. A block size which gives an optimal
variance is then chosen. Ordinary kriging is used to interpolate values into the blocks. A geostatistical technique called uniform
conditioning is then used to estimate the proportion of economic ore that occur above the Mineral Resource cut-off and this
is reported according to the SMU.

Ore Reserve estimation
The Mineral Resource models as produced by the geology department are used as the basis for the Ore Reserve. Appropriate
mining dilution is used as a modifying factor in the Ore Reserve conversion process. Appropriate Ore Reserve cut-off grades
are applied and optimised pit shells are generated taking into cognisance the economic parameters. The final pits are then
designed taking into consideration the optimised pit shell and recommended slope geometry.

Tanzania – Geita
Location
The Geita gold mine is located approximately 910km west of Dar es Salaam in the Lake Zone of northern Tanzania. The
tenement is situated within the Sukumaland Greenstone Belt of the Lake Victoria goldfields which hosts other gold mines
including Golden Pride, Bulyanhulu, Tulawaka and North Mara. This geological terrain is considered to be one of the most
productive Archaean Greenstone Belts in East Africa. Mining at Geita is undertaken by standard open-pit mining methods.
Geology
The Geita Greenstone trend is a component of the Sukumaland Greenstone Belt; it strikes east-west, is 60km long and up to
15km wide. The terrain is made up of upper to mid-Nyanzian greenstone facies rocks, mainly clastic sediments, intermediate
to felsic volcanoclastics and Banded Iron Formation (BIF) that forms a sedimentary sequence up to 1,000m thick.
In the mine lease area, north-west trending deformation corridors separate the Geita Greenstone trend into three distinct
sub-terrains. Namely, Nyamulilima in the west (hosting the Star and Comet, Ridge 8, and Roberts deposits), Geita in the
central part (hosting the Nyankanga, Geita Hill, Lone Cone, and Chipaka deposits) and Kukuluma to the north-east (hosting
the Matandani, Kukuluma, and Area 3 West deposits). Approximately 83% of this Mineral Resource is situated in the Geita
Sub-Terrain, with 13% in the Nuyamulilima Sub-Terrain, and 4% in the Kukuluma Sub-Terrain.
Late dextral faults have utilised these corridors, reactivating the pre-existing fault systems. Gold mineralisation and
hydrothermal alteration of the host lithologies, on all scales, is associated with late stage ductile to brittle-ductile deformation.
Exploration
As part of the risk mitigation strategy, securing Mineral Resource ounces for the period 2011 to 2013 is the primary focus of
Geita’s exploration drilling programmes. To this end, infill drilling, leading to Mineral Resource model revisions in 2009, has
occurred at Star and Comet and Nyankanga Cuts 5 and 6. Infill drilling began at Nyankanga Cut 7 and Geita Hill Cut 1 in the
fourth quarter of 2009 and the Mineral Resource models for these deposits will be revised in the first quarter of 2010.

The focus of the mine’s regional exploration program in 2009 and 2010 is relatively low level work involving mostly ground
geophysics, structural analysis, and preliminary drilling to follow up on the targets identified during the 2008 airborne
geophysics surveys. The result of these surveys will be the development of drill targets for 2011 onward.
Projects
With approximately 58% of the Kukuluma Sub-Terrain Mineral Resource comprising refractory ore, currently not economically
treatable in the Geita treatment plant, a metallurgical project has been initiated to determine a treatment method for this
material. Success in this regard could significantly increase the potential of the Mineral Resource extension below the
Kukuluma and Matandani open pits.
With 3.6Moz of Mineral Resource potentially exploitable by underground mining methods, Geita has begun an underground
mining project to convert this Mineral Resource to Ore Reserve. In 2009, the focus of this project has been the Nyankanga
underground area, which is the most economically viable. The strategy has been to evaluate the eastern, “near surface” portion
of the project area and investigate whether it would support a pilot underground mining implementation aimed at paying for
additional underground exploration development, proving up the predominantly Inferred underground Mineral Resource and
firming up on the eventual mining method to be employed. This project, known as “Block 1”, has been shown to be
economically viable and will be infilled in the first quarter of 2010 to increase the confidence in the current Mineral Resource
prior to implementation of the pilot study.
To facilitate the underground mining project, the mine has generated a 3D geological model of the Geita Trend that will
amalgamate structure and mineralogy so as to optimise the definition of underground Mineral Resource extensions. The
diamond drill core from the Nyankanga Cut 7 and Block 1 infill programmes will be used to enhance this model, which is
expected to be completed by the end of 2010.

Exclusive Mineral Resource
The Exclusive Mineral Resource at Geita totals 6.15Moz and comprises predominantly Mineral Resource that occurs between
the Ore Reserve pit shell and the Mineral Resource pit shell. This material is sub economic to mine at the current Ore Reserve
gold price and forms potential extensions to the LOM in an elevated gold price environment. A significant portion of this
material is in the Inferred Mineral Resource category and infill drilling programs are planned to upgrade potentially economic
areas to Indicated Mineral Resource.
The Exclusive Mineral Resource forming part of the mine’s business plan comprises approximately 0.5Moz from underground
extensions to the Nyankanga open pit and 0.067Moz from Inferred material located within the design pits. While the economic
viability of the in-pit material is known, scoping and pre-feasibility studies are currently in progress to determine the economic
viability of the underground material. As part of these studies, exploration drives and infill drilling are planned to upgrade the
confidence category of the Mineral Resource.
In instances where the orebody extends down dip, below the current LOM design pit shell and could potentially be exploited
by underground mining methods, a 35m crown pillar forms part of the Exclusive Mineral Resource below the open pit limits.
This material is not planned to be mined.
Inferred Mineral Resource in pit optimisation
No Inferred Mineral Resource is included in the pit optimisation exercise. Although it does not contribute to the economic
assessment of the optimised pit, because it is “switched-off” during the optimisation runs, it is present within the final pit shell
as Exclusive Resource. The magnitude of this Inferred material is quantified below:

The Australian assets were acquired at the end of 1999 and comprise Sunrise Dam gold mine and the Tropicana project.
AngloGold Ashanti owns 100% of Sunrise Dam gold mine. The Tropicana project is a joint venture with Independence
Group NL in which AngloGold Ashanti Australia Limited (AGAA) holds 70%. AngloGold Ashanti sold its 33.33% interest in
Boddington gold mine to joint venture partner Newmont Mining Corporation, with the sale completed in June 2009.
The Tropicana deposit represents a discovery in a new gold province in which the joint venture partners have a dominant land
position and competitive advantage in understanding the mineralised system. Exploration potential in the district is high and
a number of large targets have been identified.

Ore Reserve estimation
The Ore Reserve is estimated within the current pit design using the relevant Mineral Resource models and updated
geotechnical and metallurgical parameters and appropriate operating costs. The recoverable gold Mineral Resource model
has been estimated either by a geostatistical technique called multiple indicator kriging or uniform conditioning (non-linear
geostatistical methods) and reflects the selectivity or SMU of the mining equipment that is intended to be used to recover the
Mineral Resource within the Ore Reserve pit design.
Modifying factors
The Ore Reserve cut-off grade for the Sunrise Dam open pit is based on a US$800/oz gold price at an US$/A$ exchange rate
of 0.8, with an average metallurgical recovery of 85.5%.
The Ore Reserve cut-off grade for Sunrise Dam underground is based on a US$800/oz gold price at an US$/A$ exchange
rate of 0.8, with an average metallurgical recovery of 85.5%.
The Ore Reserve cut-off grade for Tropicana is based on a US$900/oz gold price at an US$/A$ exchange rate of 0.85, with
an average metallurgical recovery of 91.2%. The economic parameters used for Tropicana ore reserve estimation are sourced
from the Tropicana joint venture enhanced pre-feasibility study.

Australia – Sunrise Dam
Location
Sunrise Dam lies some 220km north-north-east of Kalgoorlie and 55km south of Laverton in Western Australia. The mine,
100% owned by AngloGold Ashanti, comprises an open-pit operation and an underground mine. Mining is carried out by
contractors and ore is treated in a conventional gravity and leach process plant. The mining of the open pit has reached its
final depth and only a small north wall cutback is still in operation.
Geology
At Sunrise Dam, gold mineralisation is structurally controlled and vein hosted. The style of mineralisation can be differentiated
depending on the structure or environment in which it is hosted. There are three dominant domains recognised:
Shear-related and high strain – e.g. Sunrise Shear Zone;
Stock work development in planar faults with brittle characteristics (these occur in all rock types and are commonly
concentrated at lithofacies contacts within the volcanic stratigraphy or the porphyry margin and within hinge domains within
the magnetite shales) – e.g. Western Shear Zone, Watu, Cosmo, Summercloud; and
Placer-style mineralisation hosted within the fluvial sediments.
The vein and shear styles of gold mineralisation are introduced primarily during the third and fourth deformation stages and
variations in structural style, ore and gangue mineralogy and alteration intensity are observed locally. Secondary (supergene)
gold mineralisation is also an important part of the Cleo-Sunrise ore system and is highlighted by extremely high gold grades
developed near the base of Tertiary palaeo-channels and horizontal blankets of mineralisation related to iron redox fronts and
associated water tables.
Exploration
Near-mine exploration at Sunrise Dam is specifically focused on a two-stage strategy of developing and advancing proximal
opportunities to the open pit and underground operations, whilst determining long-term opportunities that exist up to 1.5km
below the mine. In 2010, $10 million will be spent on the initial stage of near-mine exploration with a strategy of growing the
Mineral Resource base to 20Mt by December 2011, whilst ensuring that Sunrise Dam can always deliver on its business
promises. This is achievable with a secure tenement holding, comprising in excess of 200km
2
within the central Laverton
Greenstone Belt and high-quality targets immediately proximal to and below the mine area.
In addition to projects within the AGAA-owned tenure, strategic joint ventures continue to be developed. These opportunities,
coupled with world-class, cutting-edge geological research and development initiatives, support a well-developed strategy
that will provide the best opportunity to successfully develop a strong and diverse project portfolio.

Projects
The underground project seeks to delineate the deep Mineral Resource below the mine area. The extensions of the current
orebodies can be traced to depths in excess of 1.2km vertical and extend over a strike length of 2.5km. This, in addition to
the satellite underground and open pit opportunities, forms the framework for the LOM at Sunrise Dam.
Mineral Resource Estimation
Open-pit estimates are generated using a geostatistical method called multiple indicator kriging. All available geological
drillhole information is validated for use in the models and the local geology of the orebody is used to classify the drillhole
information into appropriate geostatistical domains. Detailed statistical analyses are conducted on each of these domains and
this allows for the identification of high-grade outliers. If these values are anomalous to the general population characteristics
then they are cut back to the appropriate upper limit of the population.
Estimation of the underground Mineral Resource uses the geological model boundaries to subdivide all drillhole data into
appropriate domains. Statistical analyses are performed on these domains and, in a similar manner to that of open-pit
estimation, high-grade outliers are identified and appropriately cut back to the upper limit of the population. A geostatistical
method called ordinary kriging is used to produce estimates of a pre-determined block size. These block sizes are 10m x 10m
and 20m x 20m. The geostatistical technique of conditional simulation has been used to estimate the Cosmo ore zone.

Australia – Tropicana
Location
The Tropicana gold project is located 330km east north-east of Kalgoorlie, Western Australia. The mineral deposit is hosted
in tectonically-reworked Archaean rocks that form the eastern margin of the Yilgarn Craton. Tropicana is the first deposit
discovered in this remote portion of the Great Victoria Desert and is widely regarded as defining an emerging greenfields
gold province.
Together, the Tropicana and Havana deposits define a north-east trending mineralised corridor ~1.2km wide and ~5km long
that has been tested to vertical depth of 400m. The Mineral Resource remains open down-dip for both the Tropicana and
Havana deposits, and along strike to the north of the Tropicana deposit and south of the Havana deposit. Neither the
immediate metamorphic host rocks nor mineralised zones are exposed at surface due to the presence of widespread cover
sequences (0.5–15m thick).
Geology
The Tropicana deposit comprises one main ore zone (2-50m thick) and subordinate thin (3-5m), discontinuous mineralised
lenses that typically return intercepts <0.5g/t gold. The Havana deposit comprises a lower, laterally continuous higher-grade
lode (2-50m thick) that is overlain, in central and southern parts of the proposed pit, by stacked, typically lower-grade and
thinner (5-25m) ore zones dominantly hosted in quartzo-feldspathic gneiss.
Models of the mineralised envelope (>
– 0.3g/t) define a wavy, asymmetric foliation that is broadly sub-parallel to dominantly east
to south-east dipping gneissic banding and local stratigraphic divisions. The foliation is deflected approaching discrete high-
strain sericite-biotite-chlorite±graphite shears that are anomalous in gold. Three distinct structural domains can be identified:
Tropicana, Havana North and Havana South. The northern margin of the Tropicana domain is defined by the east-northeast-
striking and southerly-dipping Boston Shaker Shear Zone. The Tropicana and Havana domains are separated by north-east
to east-striking, variably-dipping structural discontinuities defined by the Muddler, Swizzler and Cobbler Shears. At Havana,
the boundary between the northern and southern structural domains is coincident with an east-west-striking steep fault (Don
Lino Shear).

In detail, single lodes comprise multiple stacked higher-grade (>– 3g/t) lenses within a lower grade (>– 0.3g/t) envelope. Single
high-grade lenses and their medium grade halos locally converge to form thicker, composite mineralised zones. The geometry
is interpreted as a linked shear system that in drill core manifests as discontinuous biotite-pyrite shears which are developed
on a mm to cm scale.
Sulphides within the ore zones are dominated by pyrite (2-8%, <0.2mm) with accessory pyrrhotite, chalcopyrite, electrum and
telluride minerals, and trace minerals including, but not limited to, sphalerite, galena and bornite. Free gold occurs as fine-
grained (typically 10-30 microns) inclusions within pyrite and less commonly along biotite-sericite fractures cutting silicate
minerals. Mineralisation was strongly influenced by the character of precursor metamorphic facies at scales ranging from
single grains and crystal-clusters (mm to cm scale) to preferential concentration of gold in rheologically and/or chemically
favourable K-feldspar-rich facies of the quartzo-feldspathic gneiss association (deposit scale).
Gold mineralisation is temporally related to shear planes that post-date the main gneissic fabric developed during, peak
(granulite facies) metamorphism. Permeability created during brittle fragmentation was accompanied by synchronous
partitioning of strain into pervasively biotite-sericite-pyrite-altered dissolution and shear planes that envelop more competent
lithons. Sulphide and gold mineralisation formed from higher temperature (>350°C) silica-undersaturated fluids that were
buffered by the wall rock at variable oxidation states.
Exploration
The Tropicana joint venture has assembled a dominant land-holding within an emerging greenfields belt. Maximising the value
of the known Mineral Resource and capitalising on the strategic ground holding is dependent on timely application of
exploration expenditure. Progressive focusing of expenditure in tenure shown to be more prospective and relinquishment of
less prospective parts of the portfolio will heighten the probability of discovery. This approach will best be achieved through
sustained investment in systematic exploration.
Capitalising on the joint venture first mover advantage is dependent on systematic exploration of regional targets (>60km from
Tropicana), near resource targets (<60km), and extensions of the known Mineral Resource that may form part of an
underground Mineral Resource. The exploration strategy aims to balance short- to longer-term value creation through
sustained deployment of expenditure within the portfolio of early-, mid- and later-stage prospects and targets.
The key objectives for 2010 can be summarised as:
defining additional higher value ounces to maximise the value of the Tropicana gold project;
identifying the potential scale of the underground Mineral Resource at Tropicana and Havana that can complement
conceptual open-pit mining and extend the conceptual mine life; and
progressing exploration in the wider Tropicana Belt to leverage the value that may be unlocked at a province scale with the
objective of making further greenfield discoveries.
Projects
The Tropicana gold project is currently the focus of a bankable feasibility study into the viability of open-pit mining. The study
is due for completion in the second half of 2010.
Mineral Resource estimation
The geostatistical method of uniform conditioning is used to estimate the Mineral Resource. All available geological drillhole
information is validated for use in the models and the local geology of the orebody is used to classify the drillhole information
into appropriate geostatistical domains. Detailed statistical analyses are conducted on each of these domains and this allows
for the identification of high-grade outliers. If these values are anomalous to the general population characteristics, then they
are cut back to the appropriate upper limit of the population.
Mineral Resource has been reported above a marginal (break-even) cut-off grade of 0.6g/t for oxide and transitional material
and 0.7g/t for fresh material, within a US$1,000 optimisation at an US$/A$ exchange rate of 0.8.

Regional overview
In March 1999 AngloGold Ashanti acquired the Pikes Peak Mining Company, and interests in the Cripple Creek & Victor Gold
Mining Company (CC&V) and the Jerritt Canyon joint ventures. Due to the merger of Golden Cycle Gold Corporation into a
wholly-owned subsidiary of AngloGold Ashanti effective July 1, 2008, CC&V became an indirect, wholly-owned joint venture
of AngloGold Ashanti Limited.
CC&V currently controls over 85% of the patented claims within the district and 100% of the land within the 2009 Mineral
Resource. The Ore Reserve and Mineral Resource are stated at 100% ownership basis, although portions of the Ore Reserve
are subject to third party royalties that vary according to individual agreements with the underlying property owner.
Mineral Resource estimation
A single unified Mineral Resource model has been developed for the entire district. The unified model encompasses all known
deposits and drilling within the CC&V property. The estimation method is multiple indicator kriging and the primary variable
estimated is the recoverable gold.
An estimated iron and oxide model is utilised to interpolate block specific coefficients for input into the metallurgical recovery
function. The method for calculating nominal shake leach values is a regression technique using geologically logged
categorical variables. Modelling software is MineSight
®
and updated drillhole information is used throughout. The drillhole
database is thoroughly reviewed before each Mineral Resource estimation and the estimation domains are based on lithology
and structural domains for each deposit.

Ore Reserve estimation
The Ore Reserve pit designs were based on LG optimisations of the Mineral Resource model. The LG algorithm applies
economic values to individual blocks and then generates a pit shell based on geotechnical constraints. Successive nested
shells are generated until the economic limits of the pit are established. These shells are then used as a template for final mine
design. Pit slope designs for all deposits were based on geotechnical studies and range between 32° and 57°. All pits were
designed using a 10.7m (35 feet) bench height except the South Cresson which utilises 6.1m (20 feet).

United States – CC&V
Background
CC&V is located south-west of Colorado Springs in the state of Colorado in the United States. Large-scale surface mining
began in 1991 and grew with the start of production at the CC&V Cresson project in 1994. Today, CC&V is a low-grade, open-
pit operation. The ore is treated using a valley leach facility (VLF) with activated carbon used to recover the gold. The resulting
doré buttons are shipped to a refinery for final processing.
Geology
The mining district is located between the towns of Cripple Creek and Victor. The dominant geological feature is a Tertiary-
aged, diatreme intrusive complex 6.4km long and 3.2km wide. The diatreme-intrusive complex is hosted in Precambrian age
rocks including biotite gneiss, granodiorite, quartz monzonite and granite.
The diatreme is primarily composed of highly variable breccias and volcanoclastics that have been intruded by stocks, dykes,
sills and discordant breccias. These rocks, primarily phonolitic in composition, were followed by late lamprophyre dikes and
breccia pipes. The host rocks have undergone a complex history of structural deformation and hydrothermal activity and
alteration. Gold mineralisation post-dates volcanic activity, and is hosted in all rock types as veins and disseminated and/or
structurally-controlled orebodies. The gold mineralisation has been dated between 27.8 and 26.6Ma. District structures are
generally near vertical and strike north-north-west to north-east. These structures commonly controlled the intrusions and
acted as primary conduits for late-stage, gold mineralising solutions.
Higher grade pods of mineralisation occur at structural intersections and/or as sheeted veins along zones of strike deflection.
High-grade gold mineralisation is also associated with K-feldspar + pyrite +/- carbonate alteration and occurs adjacent to the
major structural and intrusive dyke zones. The broader zones of disseminated mineralisation occur primarily as micro-fracture
halos around the stronger alteration zones in the more permeable Cripple Creek breccia wall rocks. The average depth of
oxidation is 120m and is also developed along major structural zones to even greater depths. Individual orebodies can be
tabular, pipe-like, irregular or massive. Individual gold particles are generally less than 20 microns in size. Gold occurs as native
gold with pyrite, native gold and gold-silver tellurides. In the oxide zone, gold occurs with hydrous iron and manganese oxides.
Silver is present but is economically unimportant. Iron and manganese oxides, pyrite, K-feldspar alteration and quartz can
encapsulate gold mineralisation locally.

Mine life extension project
CC&V has implemented a mine life extension (MLE) project that extends the LOM. The MLE mining area utilises a lower cut-
off grade from four of the design pits (Cresson, South Cresson, Wild Horse Extension and Globe Hill) to generate the ore
tonnage needed. Processing and recovery of the additional gold will be completed through a phase 5 extension of the existing
VLF. Overburden resulting from mining in these extension areas will be placed into portions of the existing main Cresson mine,
east Cresson mine, and north Cresson mine as mine backfill or placed for storage in the existing Squaw Gulch Overburden
storage area. Approximately 113Mt of additional ore and 231Mt of additional overburden will be mined within the proposed
MLE areas for a total of 344Mt over the additional five years of mining in the MLE area. The ore will be crushed and processed
using the existing crushing and conveying facilities. Ore will be processed on the existing VLF and the phase 5 extension, and
recovered in the existing process facility.

Exclusive Mineral Resource
The Exclusive Mineral Resource at CC&V lies peripheral to, and along, mineralised strike extensions in the current pit designs.
None of this material was brought into the Ore Reserve during 2009 as CC&V is currently engaged in a MLE pre-feasibility
study. The study will be completed during 2010 and a portion of the material is then expected to be brought into the Ore
Reserve in 2010.

Regional overview
AngloGold Ashanti has three operations in South America – Cerro Vanguardia in Argentina, and AngloGold Ashanti Brasil
Mineração (Brasil Mineração) and Serra Grande in Brazil. Combined, these operations produced 598,000oz of gold in 2009,
equivalent to 13% of group production and 6% more than in 2008. In addition, AngloGold Ashanti has had an active
exploration programme in Colombia for some years, with the most favourable of the prospects being in the La Colosa district.
The exploration programmes in Argentina and Brazil were recently expanded.
The Mineral Resource in South America attributable to AngloGold Ashanti, including the Colombia Mineral Resource, totalled
29.16Moz at year-end, and the attributable Ore Reserve, 4.41Moz.
Mineral Resource estimation
The Mineral Resource estimates are computed using the relevant computer modules of Datamine
®
software package. The
geological model is a critical part of the Mineral Resource estimation process. The orebody boundaries for each geological
entity (veins, stock work, wall rock) are defined from the detailed logging of all geological boreholes and after validation this
information is used to create a three dimensional model. This model is subsequently overlain with a 5 x 25 x 5m (X by Y by Z)
block model. The block sizes used are chosen to represent the dimensions in which the deposit is intended to be mined.
Volumetric measurements of the orebody are subsequently computed in the system using the relevant block dimensions.
Ordinary kriging is used to perform the grade interpolation. Field tests are conducted to determine appropriate in-situ densities.
Stochastic simulations are performed in the main orebodies for uncertainty assessment and the Mineral Resource is then
classified into the Measured, Inferred and Indicated categories according to stringent rules.

Ore Reserve estimation
The appropriate Mineral Resource models are used as the basis for the Ore Reserve. All relevant modifying factors such as
mining dilution and costs are used in the Ore Reserve conversion process. This is based on the original block grades and
tonnage and includes waste material (both internal and external). Appropriate Ore Reserve cut-off grades are applied and all
blocks above this cut-off are reported. For the reserve optimisation, Whittle
®
software was used and Datamine
®
software was
utilised to design the pits.
It is important to emphasise the importance of the silver during the optimisation of the pits, since silver is a significant
by-product at Cerro Vanguardia. The ratio of silver to gold commonly ranges from 10 to 15g/t of silver per 1g/t of gold.
Cerro Vanguardia uses conventional open-pit mining with a doubled bench height of 20m. Mining is distributed between
multiple operating pits, typically three to five at any one time; depending on the plant feed requirements. Waste dumps and
heap-leach stockpiles are located adjacent to each pit. Plant grade ore feed is trucked to either the long-range or short-range
stockpiles in order to smooth out the head grades and avoid recovery losses due to higher than planned silver grades.
The average stripping ratio for the remaining 10 years of mine life is 23:1.

Geology
Cerro Vanguardia is located in the central portion of the 60,000km
2
Deseado Massif, the most extensive morphological and
stratigraphical unit in southern Argentina. The Deseado Massif consists of Palaeozoic low-grade metamorphic basement
rocks, unconformably overlain by a thick sequence of Lower to Upper Jurassic volcanic and volcanoclastic rocks of
intermediary and acidic composition. These older rocks are exposed in erosional windows through overlying Cretaceous
sediments and Tertiary to Quaternary basalts.
The oldest rocks in this part of Patagonia are of Precambrian-Cambrian age which are overlain by Permian and Triassic
continental clastic rocks which have been faulted into a series of horst and graben structures, and are associated with both
limited basaltic sills and dykes and with calc-alkaline granite and granodiorite intrusions.
Gold and silver mineralisation at Cerro Vanguardia occurs within a vertical range of about 150 to 200m, in a series of narrow,
banded quartz veins that occupy structures within the Chon Aike ignimbrites. These veins form a typical structural pattern
related to major north-south (Concepcion) and east-west (Vanguardia) shears. Two sets of veins have formed in response to
this shearing: one set strikes about N40W and generally dips 65° to 90° to the east while the other set strikes about N75W
and the veins dip 60° to 80° to the south.
The veins are typical of epithermal, low-temperature, adularia-sericite character and consist primarily of quartz in several forms
such as massive quartz, banded chalcedonic quartz and quartz-cemented breccias. Dark bands in the quartz are due to finely
disseminated pyrite, now oxidised to limonite. The veins show sharp contacts with the surrounding ignimbrite, which hosts
narrow stockwork zones that are weakly mineralised, and appear to have been cut by a sequence of north-east trending faults
that have southerly movement with no appreciable lateral displacement.

Brazil – Brasil Mineração
Brasil Mineração
Brasil Mineração has mining rights over 61,864ha in the state of Minas Gerais in south-eastern Brazil. The Brasil Mineração
complex is located in the municipalities of Nova Lima, Sabará and Santa Bárbara, south and east of the city of Belo Horizonte
and within the mining district referred to as the Iron Quadrangle (Quadrilátero Ferrífero). This area hosts numerous historic and
current gold mining operations, as well as a number of open-pit limestone and iron ore operations. Currently AngloGold
Ashanti mines gold-bearing ore at the Cuiabá underground mine and from the Córrego do Sítio heap-leach mine.
Cuiabá
The gold mineralisation at Cuiabá mine is associated with sulphides and quartz veins in BIF and volcanic sequences. Where
the BIF is mineralised, the ore appears strongly stratiform due to the selective sulphidation of the iron-rich layers. Steeply
plunging shear zones tend to control the ore shoots, which commonly trend parallel to intersections between the shears and
other structures. The controlling mineralisation structures are the intersection of thrust faults with tight isoclinal folds in a ductile
environment. Mineralisation is due to the interaction of low salinity carbon dioxide rich fluids with the high-iron BIF, basalts and
carbonaceous graphitic schists. Sulphide mineralisation consists of pyrite and pyrrhotite with subordinate arsenopyrite and
chalcopyrite; the latter tends to occur as a late-stage fracture fill and is not associated with gold mineralisation. Wallrock
alteration is typically carbonate, potassic and silicic.
Córrego do Sítio
The Córrego do Sítio orebodies are situated about 30km to the south-east of Cuiabá mine and consist of narrow north-
east/south-west elongated lenses dipping at 20º to 30º. Córrego do Sítio is an orogenic type deposit and comprises many
hydrothermal lodes with quartz veins and low sulphide content disseminated in the wall rocks. The mineralised orebodies are
narrow, elongated and folded. In general, the mineralised orebodies are sericitic zones and quartz veinlets. The gold occurs
as microscopic or sub-microscopic inclusions in arsenopyrite and sometimes in berthierite. Other typical sulphide minerals in
the orebodies are pyrrhotite, pyrite and chalcopyrite.

Lamego
The Lamego mine is located in the northwestern part of the Iron Quadrangle metallogenetic province, close to the Cuiabá
gold mine. Mineralisation in Lamego’s deposit is characterised by orebodies associated with shear zones in both BIF and
metacherts. The proportion of these lithotypes varies substantially from one orebody to another. In the BIF, sulphide
mineralisation occurs, while in the metachert and the quartz veins the gold occurs either as native gold or in sulphides. The
orebodies are characterised by sulphidation in the form of disseminated sulphide bands or as fracture filling. The plunge of
the orebodies coincides both with the fold axis of the first two structural events and with stretches in the same direction as
the local mineral lineation.

MMV Other
The MMV Other Mineral Resource comprises the Mineral Resource from the currently closed underground mines of Raposos
and Morro da Gloria, together with the Luzia da Motta open pit. All of these operations are located within a radius of 4km to
the Queiroz plant and Nova Lima city. The Raposos sequence is interpreted as a ductile thrust event and the main mineralised
area is associated with an anticlinal (isoclinal) fold of the same structural event. The stratigraphy sequence is repeated by folds
and consists of ultramafics, komatiitic basalts, basalts and andesites with layers of BIF. Pelites and metavolcanoclastic occur
at the top of the sequence. The mineralisation is located in folds and shear zones and occurs essentially in the BIF layers. The
orebodies are characteristically surrounded by concentric zones of hydrothermal alteration consisting of sericitisation,
carbonatisation and chloritisation. In the oxidised ore the gold tends to be finer (10 to 30 microns) and occurs in limonite.
Exploration
The Raposos mine is currently being explored with underground drilling, whilst Morro da Gloria Mine and Luzia da Motta are
targeted with surface drillholes. A dewatering program at Morro da Gloria is also in progress in order to access the orebodies.
The programme is intended to confirm and convert an Inferred Mineral Resource to the Indicated Mineral Resource category
by drilling patterns of drillholes at 60m along the plunge and 30m along the strike of the orebodies.
Projects
A conceptual study on the Cuiabá future mine was started in 2009. The strategy is to optimise Cuiabá future mine production,
without abandoning the narrow vein orebodies at the end of the mine life.
The project which comprises the MMV Other Mineral Resource at Brasil Mineração is named Nova Lima Sul (Nova Lima
South). The objective of this project is to set up a system of production that will generate sufficient ore to feed the current
spare capacity at the Queiroz plant.

Mineral Resource estimation
The Mineral Resource Estimation is updated as part of the annual evaluation process. The geostatistical method used for
estimation is ordinary kriging using the lithology as the indicator. The Cuiabá mine dataset consists of channel samples and
drillhole samples. The 3D modelling and estimation is done with two domains: the thick orebodies, comprised by the Fonte
Grande Sul and Serrotinho orebodies and the narrow vein domain of the Balancão, Galinheiro and Canta Galo orebodies.
All channel and drillhole samples are used in the 3D geological models and the lithological maps of the orebodies are used to
identify the rock types. A simulation technique is used to determine the uncertainty in the orebody block-models. SGS
(Sequential Gaussian Simulation) and SIS (Sequential Indicator Simulation) methods are use to simulate the rock types (SIS)
and the grade (SGS) combining the results in an uncertainty analysis.
Raposos and Morro da Glória are estimated as the polygonal estimates (considering a weighted average of the samples over
two drilled or open panels and an average is applied for the lower panels where no drilling information is available). Both
Raposos and Morro da Glória have the information captured into datasets and preliminary estimation exercises confirm the
current numbers in the statement (Raposos by uniform conditioning method and Morro da Glória by ordinary kriging). Luzia
da Motta estimates come from ordinary kriging estimates for each target based on the available surface drilling which has a
minimum pattern of 100 x 100m.

Exclusive Mineral Resource
The Exclusive Mineral Resource is defined as the inclusive Mineral Resource less the Ore Reserve before dilution and other
factors are applied. At Cuiabá the main Exclusive Mineral Resource (0.30Moz) comes from the main area (current production
orebodies). This Exclusive Mineral Resource is basically an Inferred Mineral Resource that will be drilled according to the
conversion plan and is located below level L15 (FGS-SER) and L13 (BAL-GAL-CGA). The secondary area comprises old
panels and satellite orebodies and is considered an Exclusive Mineral Resource (0.026Moz) until the satellites orebodies are
drilled out.

Brazil – Serra Grande
Location
Serra Grande is situated approximately 3km south of the city of Crixás in the Goiás State of Central Brazil. This location is
approximately 260km northwest of Brasilia, the country’s capital.
History
The area was first exploited by garimpeiros as open-pit workings. In 1973, Inco Limited (Inco) began reconnaissance work
including mapping, magnetic surveys, and diamond drilling. In 1976, Inco discovered gold mineralisation in the mine area. In
April 1983, Kennecott Corporation signed an option agreement to gain a 50% interest in the project. In 1986, Kennecott
Corporation sold its participation in the project to an affiliate of Anglo American plc, which continued underground
development and exploration and completed a feasibility study in 1987.
Mining started in 1987, with ore being stockpiled. The first gold bullion was produced on November 14, 1989. TVX Gold Inc.
(TVX Gold) acquired its interest in the property on January 7, 1991, through a merger with Inco. TVX Gold was acquired by
Kinross in early 2003, giving Kinross 50% ownership of the property.
Currently, Serra Grande is equally owned by AngloGold Ashanti Limited and Kinross. AngloGold Ashanti is the mine operator.
Geology
The deposits occur within the Crixás Greenstone Belt, Rio Vermelho and Ribeirão das Antes formations, of the Upper
Archaean Pilar de Goia’s Group (~2.7Ga). The stratigraphy of the belt is dominated by basic and ultrabasic rocks in the lower
sequences, with volcano-sedimentary units forming the upper successions. The gold deposits are hosted by a sequence of
schist, volcanic, and carbonate rocks, which occur in a greenstone belt structural setting. Gold is mostly associated with
quartz veins and locally with more massive sulphides. The ore shoots plunge to the northwest at between 6° and 35°. The
current understanding of the regional geology indicates that the stratigraphy in the area of the mine has been overturned and
thrust to the east.

Regional overview
In 2003, AngloGold Ashanti was the first company to start a systematic grassroots exploration program in Colombia. Since
the start of exploration, AngloGold Ashanti has staked a total of 13.9 million hectares of exploration claims countrywide. Of
these, 11.2 million hectares have been explored with systematic stream sediment sampling, prospecting and in some areas,
airborne geophysics. As a result of this work, 423 mineral contracts covering 825,025 ha are active with follow-up work from
drill target definition through pre-feasibility studies either operated 100% by AngloGold Ashanti or in joint ventures with
partners B2Gold Corp. (B2Gold), Mineros S.A, Mega Uranium and Glencore. AngloGold Ashanti has thus far relinquished
10.4 million hectares and plans to complete first stage exploration on the remaining 2.7 million hectares. To date the
programme has generated 42 drill targets of which 24 have been drilled with two resulting in significant discoveries, Gramalote
and La Colosa.

Location
The Gramalote prospect is located on the eastern side of the Central Cordillera some 80km northeast of Medellin and 230km
northwest of Bogota.
The Gramalote project is a joint venture with Vancouver-based B2Gold who is the operator of the project. B2Gold holds 49%
and is required to take the project to feasibility to obtain an additional 2%.
Geology
Mineralisation is hosted in the Antioquia batholith and bears a strong relationship to Cretaceous-Palaeocene magmatic-
hydrothermal pulses. Hornblende granodiorites and porphyritic dykes constitute the older sub-regional host. Biotitic tonalites
and granodiorites are intimately associated with Gramalote-style mineralisation.
The sub-regional control of targets is defined by dextral extensional shear zones orientated north-west/south-east to
north-north-west/south-east-east. The four principal controls on a local scale are:
1.
Extensional Steps and Tension Gashes
2.
Main Damage and Transfer Zones
3
. Extensive tectonic syntaxes
4.
Deflections of sub-regional shear zones
Hydrothermal alteration is restricted to structurally controlled veins and veinlets. The four principal alteration styles are:
Potassic K-Feldspar, Quartz-Sericite, Sericite-Carbonate and Carbonate-Epidote-Chlorite.
Mineral Resource estimation
At Gramalote, some 12,551m of diamond drilling (43 holes) have been used to support the calculation of an Inferred and
Indicated Mineral Resource.
The Mineral Resource estimate was generated using an indicator kriging method. All available geological drillhole, surface and
underground mapping information has been validated for use in the modelling process.

Colombia – La Colosa
La Colosa is a significant “in-house” greenfields project discovered by AngloGold Ashanti’s Colombia greenfields exploration
team during 2006. The project is 100% owned by AngloGold Ashanti and located 150km west of Colombia’s capital city,
Bogota and 30km west of the major town, Ibague, in the department of Tolima.
Geology
The La Colosa copper-poor porphyry gold system is genetically associated with Miocene porphyritic intrusive centres intruded
into Paleozoic schists. The highest grade gold mineralisation is closely associated with a suite of early porphyry
intrusions/breccias with potassic and sodic-calcic alteration, 5% pyrite and traces of chalcopyrite and molybdenite. The
coherent body suffered little dilution by intermineral/postmineral phases or fault propagation.
The early porphyry stage is divided into three phases. The earliest is a crowded diorite porphyry and the late-mineral dacite
porphyry is typified by rounded quartz phenocrysts, locally up to 1cm across.
Contacts between porphyry phases are commonly characterised by broad zones of intrusion breccias. The texture of the
breccias is commonly diffuse implying varied degrees of assimilations of the earlier by later phases.
Alteration and mineralisation
The paragenesis of the main alteration/mineralisation mineral assemblage observed at Colosa starts with pervasive sodic-calcic
alteration overprinted by potassic alteration and in turn cut by a sodic-calcic event. The two dominant alteration types are the
potassic and second sodic-calcic.
The three early porphyries, and their associated intrusion breccias appear to have been altered and mineralised at the same
time. There is scant evidence for veinlet introduction between the three intrusive events. The gold content of the three early
porphyry phases is similar.
The main control of gold grade in the diorite/dacite intrusive stock is the intrusive phase where the mineralisation is hosted.
Early intrusive phases present the highest and more consistent gold grade (average: >1.1g/t). The inter-mineral diorite has
average gold grades less than 0.7g/t, the late dacite phase generally only has >300ppb gold grades close to the contact with
early diorite phases. Within the gold grade variation that characterises each intrusive phase, gold grades present a second
order correlation with the alteration assemblage. The Ca-Na and K alteration with or without chloritic alteration have the best
gold grades. Areas with intense illite alteration generally have average gold grades less than 0.3g/t. The contact breccias and
hornfels developed at the contact between porphyritic rock and schist present a mineralised haloe of at least 60m with an
average gold grade of >1g/t.
Gold deportment
Gold grains vary from almost pure gold to a much lesser amount of gold-silver telluride. The chemical composition of Au-Ag-
Te grains is variable. The gold grains are generally fine grained around 15 microns. Coarse grained gold (116 microns) was
found in samples from metamorphic rocks. Gold grains occur both liberated and ”locked” in sulphides and silicates. The
percentage is not clearly established, but a significant amount of gold is associated with silicates such as K-feldspar and
plagioclase. Sulphide minerals associated with gold are dominantly pyrite and in a much lesser amount pyrrhotite
and arsenopyrite.
Mineral Resource estimation
At La Colosa, some 17,039m of diamond drilling (59 holes) have been used to support the calculation of an Inferred
Mineral Resource.
Gold grades were estimated using ordinary block kriging methodology. Kriging was performed into a parent block size
of 50m by 50m by 10m for lithological domains (wireframes) in the mineralised envelope and for the waste surrounding
mineralisation. All available geological drill-hole, surface sampling and mapping information has been validated for use in the
modelling process.

Definitions
AngloGold Ashanti Mineral Resource and Ore Reserve Report 2009

Definitions
Mineral Resource
The JORC definition of a Mineral Resource is as follows:
A ‘Mineral Resource’ is a concentration or occurrence of material of intrinsic economic interest in or on the earth’s crust in
such form, quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity,
grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific
geological evidence and knowledge. The Mineral Resource is subdivided, in order of increasing geological confidence, into
Inferred, Indicated and Measured categories.
The Mineral Resource is estimated using all drilling and sampling information along with a detailed geological model. The
geological models are based on core logging, mapping, geophysics, geochemistry and geological understanding that have
been developed for each deposit. Most of the AngloGold Ashanti deposits have been the subject of research by world experts
in the class of gold deposit.
The grade estimation for each deposit has been developed over the life of the mine and is constantly reviewed in terms of
grade control information and reconciliation with the metallurgical plant. In general, the deep South African mines utilise a
process of compound log normal macro kriging for the estimation of the Mineral Resource, while the open pits and shallow
underground mines generally use recoverable Mineral Resource models, estimated using uniform conditioning or multiple
indicator kriging.
In order to comply with the economic requirement of the definition of Mineral Resource, all AngloGold Ashanti Mineral
Resources are constrained at an upside gold price, with all other parameters being kept the same as used for estimation of
the Ore Reserve. In the underground gold mines, scoping studies are conducted on all coherent blocks of ground that lie
above the calculated Mineral Resource cut-off. These studies include all cost and capital requirements to access the block.
In the case of open pit operations, pit optimisations are conducted at the Mineral Resource gold price and all material outside
these shells is excluded from the Mineral Resource, unless it is potentially mineable from underground.
It is the opinion of AngloGold Ashanti that the Mineral Resource represents a realistic view of an upside potential to the Ore
Reserve. In interpreting the Mineral Resource it is critical to factor in the following:
The Mineral Resource is quoted in situ and has not been corrected for dilution, mining losses or recovery.
The Mineral Resource includes a high percentage of Inferred material, which, following further exploration drilling may be
converted to an Indicated or Measured Mineral Resource.
Many of the areas lying in the exclusive Mineral Resource are currently being actively drilled and are the subject of economic
and technical studies. It can, however, not be assumed at this stage that the company has intent to mine these areas.
Mineral Resource classification is based on the '15% Rule'. A Measured Mineral Resource should be expected to be within
15% of the quarterly metal estimate at least 90% of the time, while for an Indicated Mineral Resource estimate the annual
metal estimate should be within 15% of the metal estimated at least 90% of the time. For an Inferred Mineral Resource the
annual error may for 90% of the time, be greater than 15%.

AngloGold Ashanti Mineral Resource and Ore Reserve Report 2009
P
155
The process and methodology of classification are at the discretion of the competent person and involves expressing the '15%
Rule' as a required level of information, in tangible terms the spacing of the drillhole or tunnel spacing in a particular deposit.
Techniques such as conditional simulation or even an empirical reconciliation-based approach are employed. However, all
operations are responsible for demonstrating, through reconciliation, that their classification system conforms to the 15% rule
set out above.
AngloGold Ashanti quotes its Mineral Resource as inclusive of the Ore Reserve. However, in this document the exclusive
Mineral Resource is also quoted. The exclusive Mineral Resource is defined as the inclusive Mineral Resource less the Ore
Reserve before dilution and other factors are applied.
The exclusive Mineral Resource consists of the following components:
Inferred Mineral Resource within the optimised shell;
Other Inferred Mineral Resource;
Measured and Indicated Mineral Resource that lies between the life of mine (LOM) pit shell/mine design and the Mineral
Resource pit shell. This material will become economic if the gold price increases; and
Mineral Resource where the technical studies to engineer an Ore Reserve have not yet been completed.
Ore Reserve
The JORC definition of an Ore Reserve is as follows:
An ‘Ore Reserve’ is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting
materials and allowances for losses, which may occur when the material is mined. Appropriate assessments and studies have
been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic,
marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting
that extraction could reasonably be justified. The Ore Reserve is sub-divided, in order of increasing confidence, into the
Probable Ore Reserve and the Proved Ore Reserve.
In the underground operations, the Ore Reserve is based on a full mine design and in the case of open pits on a pit
optimisation followed by a final pit design. The Ore Reserve is reported according to tonnage, mean grade(s), and contained
metal inclusive of mining dilution, mining ore losses and mine call factors. These modifying factors are based on
measurements, rather than estimates. Tonnage and grade estimates for surface stockpile materials that meet Ore Reserve
criteria are itemised separately.
Only the Ore Reserve included for treatment in the business unit plan production schedule is considered in the Ore Reserve
statement. These sometimes include marginal or sub-grade ores as well as the Inferred Mineral Resource. This Inferred
Mineral Resource is not included in the Ore Reserve statement.
For all new projects, an audited pre-feasibility (as a minimum requirement) must have been completed that demonstrates the
viability of the project and meets the company’s investment requirements. This study must be signed off at the appropriate
executive level in order to demonstrate an intent on the part of the company to proceed to feasibility and ultimately to
implement the project.
