ANDEAN PRECIOUS METALS REPORTS FOURTH QUARTER AND YEAR-

END 2025 PRODUCTION RESULTS AND PROVIDES 2026 PRODUCTION

AND COST GUIDANCE

Highest production quarter of 2025, supported by record realized prices

(All amounts in U.S. dollars unless otherwise indicated)

TORONTO, ON – February 26, 2026 – Andean Precious Metals Corp. (“Andean” or the “Company”)

(TSX: APM) (OTCQX: ANPMF) is pleased to report its operational results for the quarter and year ended

December 31, 2025, along with its production, cost, and capital investment guidance for 2026. The

Company is also providing notice that it will release its fourth quarter and year-end 2025 financial results

after market close on Tuesday, March 24, 2026. Andean will host its fourth quarter and year end 2025

earnings conference call and webcast on Wednesday, March 25, 2026, at 9:00 am Eastern Time.

Alberto Morales, Executive Chairman and CEO, stated, “Andean exited 2025 with a stronger fourth

quarter production and improved momentum across the portfolio.

When viewed through a silver-equivalent lens, consolidated silver production in Q4 was approximately

1.4 million silver ounces, and 2025 consolidated silver production represents approximately 4.8 million

silver ounces, highlighting the meaningful silver exposure within our portfolio. In parallel, we advanced

exploration programs across our assets, supporting longer-term mine planning and enhancing our ability

to unlock additional value from our existing operations.

Looking ahead to 2026, we anticipate a well-balanced production profile, with approximately 45% in the

first half and 55% in the second half, reflecting the mining sequence at Golden Queen and the ore

delivery schedule at San Bartolom e. Our capital investment program for the year is aligned with our

value creation strategy and supports processing improvements and operational flexibility.

With disciplined capital allocation, a competitive cost structure, and exposure to both gold and silver

prices, the Company is well positioned to generate strong margins, free cash flow, and long-term value

for our shareholders.”

Q4 and FY 2025 Highlights:

• Fourth quarter 2025 consolidated production of 27,777 gold equivalent ounces 3 and full

year 2025 consolidated production of 99,165 gold equivalent ounces 3, near the bottom of

the Company’s full-year consolidated production guidance.

• Golden Queen produced 11,828 gold equivalent ounces3 in the fourth quarter and 45,311

gold equivalent ounces3 for the full year 2025. Production in the fourth quarter benefited from

an improved leach-cell permeability as identified earlier in the year and the implementation of

optimized ore blending and leaching strategies.

• San Bartolome produced 15,949 gold equivalent ounces3 in the fourth quarter and 53,854

gold equivalent ounces 3 for the full year 2025 with continued emphasis on leveraging

throughput capacity, optimizing recoveries, and securing long-term ore purchase agreements.

• Record realized prices: In the fourth quarter the Company achieved an average realized gold

price of $4,171/oz and average realized silver price of $59.88/oz, both higher than the spot

market averages for gold and silver prices of $4,167/oz and $55.29/oz respectively

• Golden Queen – expanded drilling program: The 2025 exploration program at Golden Queen

was expanded following positive drilling results, including approximately 3,800 metres of core

drilling added to the plan. Exploration activities during 2025 were focused on testing extensions

of known mineralization with the objective of supporting potential mine life extension. An updated

mineral resource estimate is expected to be released in mid-year 2026.

• In June 2025, the Company entered into a long-term exclusive agreement with COMIBOL

to acquire up to 7 million tonnes of oxide ore within 250 kilometres of the San Bartolome

plant, enhancing feed security and supporting potential throughput growth. First ore deliveries

are expected by the end of 2026.

Q4 and Year End 2025 Operational Results

Golden Queen Outlook

In 2025, exploration activities at Golden Queen made significant progress, marked by an expanded

drilling program launched following encouraging results. The program remains focused on extending

known mineralization and further refining mine planning, setting the stage for the 2026 exploration

program, which is now underway with the objective of extending mine life.

Building on these developments, the Company has commenced work to expand the existing leach pad

by adding capacity for an additional 3 million tonnes of ore. In addition, detailed engineering and

permitting for a new leach pad are undergoing final review. Together, these initiatives are expected to

extend leaching capacity through 2033.

To support anticipated production requirements, the mobile fleet will be increased by three additional

haul trucks, bringing the total fleet size to twelve during 2026. Golden Queen also replaced the stacker

and the agglomeration drum, improvements that enhanced ore stacking quality. The agglomeration

process improved the quality of the stacked material, while the new stacker enhanced blending and

reduced fine particle segregation. These improvements are expected to result in higher solution

percolation rates and reduced particle migration. The Merrill-Crowe Plant is undergoing an upgrade

from a capacity of approximately 3,000 gallons per minute (GPM) to 4,000 GPM, with commissioning

planned for the fourth quarter. This upgrade is expected to increase gold and silver production from

the leach pad by approximately 6 to 10% by directing a higher proportion of lower-grade solution to the

Merrill-Crowe process and reducing the volume sent to the operating pond.

San Bartolome Outlook

In 2025, San Bartolome advanced its ore supply strategy by establishing new ore purchase

agreements with local communities, supporting long-term operational stability while broadening its

network of business partners. In addition, the Company finalized a long-term agreement with

COMIBOL to acquire up to 7 million tonnes of oxide ore within a 250-kilometre radius of the

processing facility. The first delivery of ore is anticipated by the end of 2026, increasing the diversity of

feed sources over the long term and enhancing future feed strategies.

Transportation logistics at San Bartolome were notably improved in 2025, contributing to a 21%

increase in processing throughput compared to the previous year. Building on this progress, the focus

in 2026 will be on improving processing recoveries through automation initiatives and the construction

of an additional thickener, scheduled for completion in the first quarter of 2027. These process

improvements are expected to improve recovery rates by approximately 0.5% to 1.0%.

2026 Guidance

At Golden Queen, capital investment in 2026 is primarily directed toward infrastructure and mine

development initiatives supporting exploration results and potential mine life extension. Planned

expenditures include the expansion of the existing leach pad, detailed engineering and permitting for

the construction of a new leach pad, acquisition of three additional haul trucks, deferred waste

stripping, and upgrades to the Merrill-Crowe facility. These investments are intended to ensure

sufficient processing capacity and operational flexibility to support anticipated future production

requirements.

At San Bartolome, capital spending in 2026 is focused on processing enhancements and sustaining

infrastructure. Planned capital expenditures include the construction of an additional thickener and

related plant optimization initiatives designed to improve overall plant performance.
