Toronto, Ontario--(Newsfile Corp. - September 2, 2025) - Volta Metals Ltd. (CSE: VLTA) (FSE: D0W) ("Volta" or the "Company") is pleased to announce the closing of an oversubscribed non-brokered private placement for gross proceeds of $1,545,300 (the "Offering"). The Offering was comprised of the issuance of: (i) 8,441,250 units of the Company (each, a "Unit") at a subscription price of $0.08 per Unit for proceeds of $675,300, and (ii) 8,700,000 flow-through units of the Company (each, a "FT Unit") at a subscription price of $0.10 per FT Unit for proceeds of $870,000.

Each Unit was comprised of one common share of the Company (each, a "Share") and one common share purchase warrant of the Company (each, a "Warrant"), with each Warrant entitling the holder thereof to purchase an additional Share of the Company (a "Warrant Share") at an exercise price of $0.15 per Warrant Share for 24 months from the closing of the Offering.

Each FT Unit was comprised of one common share of the Company (each, a "FT Share") and one Warrant. The FT Shares will qualify as "flow-through shares" (within the meaning of subsection 66(15) of the Income Tax Act (Canada).

The Company will use the gross proceeds from the sale of the FT Units to incur eligible "Canadian exploration expenses" that will qualify as "flow-through critical mineral mining expenditures" as such terms are defined in the Income Tax Act (Canada) (the "Qualifying Expenditures") on or before December 31, 2026. The Company plans to initiate a drill program to further explore its recently acquired Springer advanced Rare Earth and Gallium Deposit and explore its Aki Critical Minerals Project. All Qualifying Expenditures will be renounced in favour of the subscribers of the FT Units with an effective date not later than December 31, 2025. The net proceeds from the sale of the Units will be used for exploration at the Company's mineral properties and general corporate and working capital purposes.

As in every financing the Company has completed to date, certain directors and officers of the Company (the "Insiders") have participated in the Offering, increasing insider holdings. An aggregate of 2,350,000 FT Units were acquired by Insiders. Such participation in the Offering by the Insiders constitutes a "related party transaction" within the meaning of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company relied on an exemption from the formal valuation and minority shareholder approval requirements provided under MI 61-101 pursuant to section 5.5(a) and section 5.7(1)(a) of MI 61-101, on the basis that the participation in the Offering by the Insiders does not exceed 25% of the fair market value of the Company's market capitalization.

In connection with the closing of the Offering, the Company paid commissions to certain finders of an aggregate of $74,466 in cash and 822,325 finder warrants (the "Finder Warrants"). Each Finder Warrant entitles the holder thereof to purchase one (1) Common Share (a "Finder Warrant Share") at an exercise price of $0.15 per Finder Warrant Share for a period of twenty-four months from the closing of the Offering. The securities issued and issuable under the Offering are subject to a statutory hold period in Canada of four months and one day from the closing date of the Offering in accordance with applicable Canadian securities laws. The closing of the Offering is subject to the receipt of all required regulatory approvals, including the approval of the Canadian Securities Exchange (the "CSE").

Exploration program

The Company is mobilizing a drill rig to its Springer REE & Ga Deposit to further test the rare earth and gallium zones. The new drilling will aid in updating the resource and potentially establish a gallium resource. The Project consists of 5,000 hectares of patented and non-patented claims and contains a historic NI 43-101 mineral resource for Total Rare Earth Oxides ("TREO") of 4.167 million tonnes ("mt") at 1.073% TREO indicated and 12.73mt at 1.119% TREO in the inferred resource category at a cut-off grade of 0.9% TREO. Mineralization starts at surface and the deposit remains open for expansion with large portions of the property underexplored for REE-Ga mineralization.

Previous drilling resulted in multiple wide, shallow intercepts of +100m at >1% TREO, including one of the final drill holes finishing in 12m at 4.96% TREO with no subsequent follow-up drilling (see Company's press release dated June 10, 2025). There were consistent elevated gallium intercepts ranging from 57 to 120 grams per tonne ("g/t") over thick intervals, including 87.5m at 76.4 g/t and 88m at 62 g/t gallium, which was never modeled in the resource. The newly designed drill program will expand from these results and provide sufficient data for an updated resource estimate, which is scheduled to be completed in Q4 of 2025.
