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 historical estimates as current min eral resources or mineral reserves . 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. This decision 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 statem ents 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
