EDMONTON, AB, Sept 18th, 2024 – Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) (“Altiplano” or the “Company”) is pleased to report on further sales of copper-gold concentrate from the El Peñón processing facility located approximately 35 kms south of La Serena, Chile and to provide ongoing operational updates in Chile.

Highlights:

• Sales of Copper-Gold Concentrate: Altiplano has sold an additional 38.7 tonnes of copper gold concentrate with a provisional value of ~C$108,000. Preliminary copper grades of the concentrate are reported at 24.5% copper. Final settlement pricing will take place against the monthly October copper and gold prices.
• Transfer of Operations to Santa Beatriz: The company is in the process of moving mining and office equipment to Santa Beatriz and the mill site. Groundwork for the office site and road improvement has been completed at Santa Beatriz to receive two storage containers and three office containers and 1 large 20,000-liter water tank. Electric cables, hydraulic pumps, generators, compressors, DDH drill rig, a scoop tram and two large fans for underground ventilation have also been moved. Next steps at Santa Beatriz include additional sampling and mapping to assess the mining opportunity. Explosives permits have been applied for in anticipation of extracting a bulk sample.
• Corporate Update: The Company also announces the resignation of Director Luis Tondo for personal reasons. Luis’s service with the company and his contribution to technical advisory has been greatly appreciated. The Company is pleased to announce the appointment of John Alcock CPA,CGA as Director of the Company. John’s background and experience with the finance and junior mining sector aligns well with the Company’s values and growth prospects.

CEO Commentary: Alastair McIntyre, President and CEO, comments, “We are pleased to announce additional ongoing concentrate sales from the El Peñón mill and moving our equipment and operations to Santa Beatriz. Processing material from mines at a potential lower cost and efficiency combined with producing high value copper-gold concentrate has significant benefits. Our focus on value aligns Altiplano for sustainable growth.”

Altiplano has generated over C$20.4 million from the recovery and sale (after processing costs) of more than 6.55 million pounds of copper with an average grade of 1.8% Cu (Jan 2018-Mar 2024). Cash flow has been re-invested into equipment, underground drilling, expanding underground development, and the start-up of the El Peñón fit-for-purpose mill and flotation plant. This progress has enabled Altiplano to establish a significant foothold in the Chilean mining community.

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. A qualified person has not done sufficient work to classify any historical estimates as current mineral resources or mineral reserves and the issuer is not treating any reference to historical estimates or sample results as current mineral resources or mineral reserves. The Santa Beatriz mine was previously in production although no detailed production records were not kept. This material was processed at the mine and sold to ENAMI and local processers. Altiplano is relying upon limited production records, underground sampling and related activities to estimate grade and widths of the mineralization to reactivate production. The decision to commence production on the Santa Beatriz deposit 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 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.
