EDMONTON, AB – June 10, 2025 – Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) (“Altiplano” or the “Company”) is pleased to announce that it has closed the second and final tranche of a non-brokered private placement financing (the “Offering”) previously announced on February 12, 2025. Total gross proceeds from the placement represents $723,750.

The first tranche of the financing was closed and announced on March 31, 2025 and consisted of 12,785,000 units (the “Units”) at a price of $0.05 per Unit, for total gross proceeds of $639,250. Each Unit consisted of one (1) common share and one-half of a share purchase warrant (the “Warrant”). Each whole Warrant entitles the holder to purchase one (1) common share of the Company at an exercise of $0.075 per common share until March 31, 2027

The second tranche consisted of 1,690,000 Units at a price of $0.05 per Unit, for total gross proceeds of $84,500. Similar to tranche 1, each Unit consisted of one (1) common share and one-half of a Warrant. Each whole Warrant entitles the holder to purchase one (1) common share of the Company at an exercise of $0.075 per common share until June 9, 2027.

The Company has the right to accelerate the expiry date of the Warrants from each tranche upon the occurrence of certain events. 

In connection with the sale of the units sold in the second tranche, Altiplano paid a total of $600 in cash and issued 12,000 finder’s warrants (“Finder’s Warrants”), on the same terms as the Warrants, to an eligible finder for certain of the Units sold. All securities issued in the second tranche are subject to a hold period until October 10, 2025. The details of finder’s fees paid in the first tranche of our Offering are outlined in our news release dated March 31, 2025.

The net proceeds of the Offering will be used for working capital to support the concentrate production cycle at the El Peñón processing facility in Chile; development costs, including a diamond drill program, at Santa Beatriz to outline a short-term production plan, and fund general admin while reviewing additional projects for potential acquisition or alternative mill supply.

The subscriptions by insiders of Altiplano for a portion of the Private Placement are a related party transaction for the purposes of Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions (“MI 61-101”), but Altiplano is relying on exemptions from the formal valuation and minority shareholder approval requirements provided under sections 5.5(a) and 5.7(1)(a) of MI 61-101 on the basis that the fair market value of the subscriptions, insofar as it involves the insiders of Altiplano, does not exceed 25% of the market capitalization of the Issuer, as determined in accordance with MI 61-101.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the (TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.

This release includes certain statements that may be deemed "forward-looking statements". All statements in this release, other than statements of historical facts, that address exploration drilling, exploitation activities and events or developments that the Company expects are forward-looking statements. The Santa Beatriz mine was previously in production mid 2010’s with little known production records. This material was processed and sold locally to a private processing facility. Altiplano is relying upon limited past production records, underground sampling and related activities to further explore and potentially develop Santa Beatriz. The decision to develop the project and extract material for potential processing is not based on a feasibility study of mineral reserves demonstrating economic and technical viability and there is increased uncertainty and economic and technical risks of failure associated with any future potential production decision. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include market prices, exploitation and exploration successes, continuity of mineralization, uncertainties related to the ability to obtain necessary permits, licenses and title and delays due to third party opposition, changes in government policies regarding mining and natural resource exploration and exploitation, and continued availability of capital and financing, and general economic, market or business conditions. Investors are cautioned that any such statements are not guarantees of future performance and actual results or developments may differ materially from those projected in the forward-looking statements.
