Altiplano Reports May 2022 Results at Farellon with Record Monthly Income

Edmonton, June 16, 2022 - Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) ("Altiplano" or the "Company") is pleased to report on the May 2022 operating results from the Farellon Copper-Gold (Cu-Au) mine located near La Serena, Chile.

During the month of May, approximately 3,432 tonnes of mineralized copper-gold material was produced at Farellon and approximately 2,750 tonnes were shipped and processed. A slight improvement is noted in the amount produced in May over April; however, the amount of processed material improved by 23% over the previous figure of 2,242 tonnes observed in April. The May copper grade at 2.0% decreased slightly compared to the previous month observed at 2.07%. The Hugo Decline advance to the 352 m has been completed. This level is expected to be operational in the next two weeks when the SW and NW subdrifts have been completed. These subdrifts will provide operational access to the high grade mineralized zone in NE and SW directions on 2 new working faces.

Revenue generated in May was approximately US$377,545 after processing costs, representing the highest monthly revenue figure recorded since Q1 2018. May revenue also represented a 19% improvement over April's revenue of US$317,738. At May month end, an additional 380 tonnes were stockpiled at the Farellon site with 1,180 tonnes in process at ENAMI. The revenue from this material will be credited in the following months after processing has been completed. A total of 1,850 tonnes are stored at the El Peñón processing facility in advance of startup. Newly mined material will be split shipped between ENAMI and El Peñón to maximize revenue and manage cash flows as the mill prepares to commence operation.

CEO Alastair McIntyre commented "We are very pleased to see the continuing trend of improved revenues as we advance to deeper high grade operating levels at Farellon. Our improving output at Farellon combined with record revenue figures bodes well as we transition to the mill start up at El Peñón expected in a few weeks."

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 the historical estimates as current mineral resources or mineral reserves. The Farellon mine was previously in production dating back to the 1970's with a reported historical production (to a depth of 70 m) yielding approximately 300,000 tonnes at an average grade of 2.5% copper and 0.5g/t gold. This material was processed locally and sold to ENAMI. Altiplano is relying upon past production records, underground sampling and related activities and current diamond drilling to estimate grade and widths of the mineralization to reactivate production. The decision to commence production on the Farellon 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.
