Altiplano Provides Update on Mining and Processing Operations

EDMONTON, AB, February 13th, 202 6 – Altiplano Metals Inc . (TSXV: APN) (WKN: A2JNFG)

(“Altiplano” or the “Company”) is pleased to announce operational updates at the Santa Beatriz

copper-gold-iron (Cu-Au-Fe) mine and the El Peñón Processing plant, located approximately 30

kilometers south of La Serena, Chile.

Highlights:

• Altiplano entered a short-term agreement with the mining contractor Andes Core Mining

(ACM) to conduct mining and processing operations for the Santa Beatriz and El Peñón

processing plant. The purpose of the agreement was to rent the operations providing APN

the opportunity to receive rental income while benefiting from further mine development

and plant optimization.

o ACM was to further develop the Santa Beatriz mine to lower level s intended to

intersect higher grade sections of the mine. This area, supported by the previous

drill program, was expected to provide new operating faces of the Iron Oxide

Copper Gold vein.

o ACM was to also operate the plant to process the material mined at Santa Beatriz

for the benefit of obtaining a rental fee while maintaining and sustaining the

processing facilities.

• Commercial terms involve d ACM paying APN US$8/tonne of material mined at Santa

Beatriz. In addition, APN was to receive US$30,000/ month for the rental of the plant.

ACM was to be responsible for all costs at each operation, mine rental fees and royalties,

including personnel, mine development, sustainability and plant maintenance. ACM was

provided the opportunity to sell the concentrate produced from the operations.

• For the months November to January a total of 3,953 tonnes were mined from Santa

Beatriz, generating an income of US$31,625.

• Development was focused on the 425 m, 400 m and 392 m levels as outlined in Figure 1.

Development was also conducted in the ceilings of the 400 m and 391 m levels

o Advancing to the 382 level, ACM reached a total of 30 of an expected 80 m

• This short-term arrangement has been suspended to review outcomes and consider

strategic opportunities to generate improved shareholder returns. Both operations have

been placed on short term care and maintenance while an optimization plan is currently

under review.

President and CEO Alastair McIntyre comments: “The decision to use a contractor to develop the mine

infrastructure to deeper levels focused on a cost-effective approach. It provided an opportunity to advance

both assets while reducing operating costs and risk , with the potential of generating sustained income .

The Company is now giving greater consideration to the rental concept and alternatives to improve

returns. Operations have been paused while this strategic review is underway.”

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 information or estimates as current mineral resources or mineral reserves . The Santa

Beatriz mine was previously in private production mid 2010’s with unknown production records . This material was

processed and sold locally to a private processing facility . Altiplano is relying upon limited past production records,

underground sampling, surface drilling and related activities to further explore, develop and potentially mine Santa

Beatriz. The decision to develop the project and extract material for 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 c ould 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 perf ormance and actual

results or developments may differ materially from those projected in the forward- looking statements. For more
