Altiplano Reports Q4 2023 Operational Results

at Farellon with Improved Cu Grade and

Output

Edmonton, Alberta--(Newsfile Corp. - February 29, 2024) -

Altiplano Metals Inc

. (TSXV: APN) (WKN:

A2JNFG) ("

Altiplano

" or the "Company") is pleased to report on Q4 2023 operation results from the

Farellon Copper-Gold-Iron (Cu-Au-Fe) mine located near La Serena, Chile.

The Company extracted a total of 9,114 tonnes of mineralized Cu-Au material and processed 8,125

tonnes during Q4 2023 at Farellon. This represents a 12% and 13.6% increase respectively from the Q3

production and processing figures. Mine production in Q4 represented the highest quarterly production

over the 2024-year period. Copper grade improved in Q4 to 1.87% representing an 8.7% increase from

the 1.72% Cu recovered in Q3. Sales of 325,328 pounds of copper in 2023 Q4 generated

approximately US$798,919 in revenue (after processing costs), an increase of 25% over the $639,458

revenue figure received in Q3 - an increase related mainly to processing higher Cu grade material.

Waste removal decreased 52% to 1,221 tonnes in Q4 2023 as the new 336 m operating level was

reached.

Work on the advance to the next level at 328m began in late November and is expected to be

intersected in April. Level 328 m will bring an additional production level, with mining planned on drifts to

the NE and SW direction.

President and CEO Alastair McIntyre comments: "In the last two years, Farellon has produced and sold

on average approximately 300,000 pounds of copper per quarter and we are pleased to see that we

closed out in Q4 2024 well above that average. Copper grades in Q4 also came in above our overall

1.8% average at 1.87%, which is an excellent achievement considering global grades of copper

average 0.5% copper. Production increases and recovery of high-grade copper, combined with the

benefits of the reduction in processing and transportation costs at the El Peñón processing plan, will

drive the operation success at APN in 2024."

At the end of December 2023, the Company had 540 tonnes in stockpiles at the Farellon site and a total

of 1,555 tonnes of stockpiles at the El Peñón mill site. An additional 8,381 tonnes of lower-grade

material are stockpiled at Farellon site and ready to be shipped for processing at the El Peñón facility

over the next several months. This stockpile will be blended with newly mined material to optimize

processing efficiencies. In addition, the Company currently has 1,314 tonnes of material in process with

third party processors. This material will be processed for copper sales and the revenue will be realized

in the coming months.

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. For more information on the Company, investors should
