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 t hat 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. For more information on the Company, investors should review
