Altiplano Intersects Santa Beatriz Vein, Receives Updated Permit, Begins Shipments to El Peñón
EDMONTON, AB, September 9th, 2025 – 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, located approximately 45 kilometers south of La Serena, Chile, and 13 kilometers south of
the Company’s El Peñón processing facility.
Highlights:
• Initial tunnel development began via the 437 m level entrance and continued 63.4 m to
intersect the Santa Beatriz Iron Oxide Copper Gold vein (IOCG) at the 425m level (Figure
1.).
• Massive sulphides (chalcopyrite, pyrite and bornite), as well as magnetite were observed
in the vein.
• Mining of mineralized material has begun in two directions along the north and south
vein extensions at Level 425.
• September extraction is projected at 3 ,000 tonnes, with daily production targeted
between 120 and 140 tonnes.
• Shipments to the El Peñón processing facility have begun supporting the production of
copper/gold and iron concentrates.
• New development will begin on the lower tunnel, accessed through the 414 m opening,
to support mining on 2 additional operational north and south faces located at the 400m
level.
o Work is expected to begin the week of September 15th and Intersection of the 400m
level is expected early October
• The SERNAGEOMIN (the Chilean mining authority) has approved the application for mine
planning and expansion at Santa Beatriz for a 42-month period. The permit includes:
o extraction of up to 4,275 t/m
o approval for two additional mine openings (3 in total) creating the opportunity for
further expansion
o Additional tonnage and extensions can be applied for as development progresses.
President and CEO Alastair McIntyre comments: “The ramp developments at the 425m and 400 m levels
represent a key milestone in advancing the Santa Beatriz mine toward maximum output. Access to the
vein structure at lower levels and through multiple faces enables the extraction of high-grade copper/gold
and iron material supporting increased production potential. Material supplied from Santa Beatriz to our
plant addresses our goal of integrating our copper/gold and iron production and processing businesses.
We are also very pleased to receive the mine extension permit at Santa Beatriz providing us the opportunity
to increase mineral production and sale of copper/gold and iron concentrates.

The decision to develop the historical Santa Beatriz mine is not based on a feasibility study of mineral reserves demonstrating economic and
technical viability and there is increased uncertainty of economic and technical risks of failure associated with any potential production
decision.

Altiplano has generated over C$23.8 million from the recovery and sale (after processing costs) of more
than 8.2 million pounds of copper with an average grade of 1.8% Cu (Jan 2018 to Mar 2025). Cash has
been re -invested into acquisition, exploration, new equipment, underground drilling, expanding
underground development and production, and the completion of the El Peñón copper -gold-iron
processing facility located 30 km from La Serena, Chile.

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