Altiplano Reports on Processing Updates with

Production of Cu-Au and Iron Concentrates at

El Penon

Edmonton, Alberta--(Newsfile Corp. - February 20, 2024) -

Altiplano Metals Inc

. (TSXV: APN) (WKN:

A2JNFG) ("

Altiplano

" or the "Company") is pleased to report on the progress at the El Peñón

processing facility located approximately 15 kms from the Farellon copper-gold mine, 35 kms south of

La Serena, Chile.

As part of the ongoing optimization process at the processing facility, several refinements focusing on

the milling and flotation processes have been completed for the crushing, milling, and flotation circuits.

These adjustments were designed to improve the overall milling process efficiencies and resulted in

enhanced productivity, together with increased production of concentrates while completing ongoing

adjustments.

This work included:

Gearing replacement, transmission alignment, and mechanical adjustments for the two ball mills to

optimize spin rate and particle grinding.

New instrumentation for the pulp pump systems, and conveyors which will improve the flow rates to

the mills and milled product to the flotation systems.

An upgraded hydro-cyclones classification system was installed to improve the flow of crushed

material to the flotation cells.

Speed adjustments to the agitation reducers were completed in the flotation process to promote

optimal recovery of copper/gold.

The inaugural production of copper/gold and iron concentrates were generated from the fully

integrated and operational plant.

The enclosure of plant facility and warehouse building was completed, mainly for noise control.

President and CEO Alastair McIntyre commented; "We are pleased with the results of the design and

optimization improvements, and we have now produced the first copper/gold and iron concentrates at

the plant. This is an exciting moment in the progression of the Facility and for APN. With this milestone,

we can focus on concentrate sales and ultimately improve our bottom line."

The completion of the recent work provides the benefit of improving concentrate production and the

efficient integration of the copper-gold concentrate circuit with the iron separation and filter press

systems. The iron separation and filter circuits are designed to reduce tailings output (producing iron

concentrate) and water consumption (through recycling). Power supply continues from generators while

the company waits on the final connection from the electricity supplier.

The first copper/gold and iron concentrates produced from the facility are currently stored at the site and

will be shipped for sale. Processing of the lower grade stockpiles used for the start-up process at the mill

site continue and are producing concentrates with average grades of 24% Cu and above, and gold at

1.5 grams/tonne on average, as well as iron ranging from 68% to 71% Fe.

Shipment and processing of new mined high-grade material will be used to improve output, concentrate

grade, and returns as the mill begins full operational capacity beyond start up. In the meantime, the

Company manages its cash flow needs from selling copper-gold material to third part processors as

concentrate production reaches maximum output.

APN Hires Osbaldo Zamora Vega as V.P. Technical Operations

President and CEO Alastair McIntyre further comments: "We are pleased to welcome back Osbaldo as

VP of Technical Operations.

Osbaldo will oversee the development of APN's current mineral assets and

review potential acquisition targets with near-term production opportunity in addition to sourcing large

scale exploration targets with upside potential within the region. Osbaldo's technical background and

previous experience with the Company are well suited to lead the growth mandate of APN."

Osbaldo Zamora Vega has over 20 years of geological experience that ranges from greenfield

exploration to underground mining. He has worked for major companies in Mexico such as Fresnillo

PLC at La Cienega mine and, most recently, he served as Director of Geology for Discovery Silver

throughout the PEA and PFS studies of their Cordero Project in Chihuahua. Additionally, he has led

exploration programs for several junior companies in Canada and Latin America. He previously served

as VP Exploration for Altiplano Minerals in Chile. Mr. Zamora holds a Ph.D. in Economic Geology from

the University of Alberta, Canada, a M.Sc. in Geochemistry from the National Autonomous University of

Mexico, and a B.Sc. in Geology from the Autonomous University of San Luis Potosi, Mexico.

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
