NI 43-101 TECHNICAL REPORT FOR SAN BARTOLOMÉ

TORONTO, ON – February 16, 2024 – Andean Precious Metals Corp. (“Andean” or the

“Company”) (TSX -V: APM) (OTCQX: ANPMF) today filed the Preliminary Feasibility Study

Technical Report for San Bartolom é Mine Bolivia dated February 6 , 2024 (the “ Technical

Report”).

The Technical Report was prepared by SRK Consulting (U.S.) Inc. in compliance with National

Instrument 43-101 – Standards for Disclosure for Mineral Projects (“NI 43-101”) and has been

filed on SEDAR+.

Andean previously released the results of the mineral resource and mineral reserve statement

(see news release dated December 27, 2023), showing an extension of 4.6 years for the San

Bartolomé operation based on a new proven and probable (“2P”) mineral reserve estimate.

“The Technical Report filed today further underscores the tremendous strides we have made to

replenish our reserves and resources and extend the operating life of San Bartolomé,” stated

Alberto Morales, Andean’s Executive Chairman and Chief Executive Officer. “Pursuing

opportunities that drive cash flow and profitability is our key priority in Bolivia. Topping our list of

growth initiatives remains securing more feedstock through new long-term third-party contracts

and from the Bolivian government. In parallel, our team is evaluating potential drill programs at

Tollojchi, Altavista, and Paca and regional M&A opportunities.”

Key Highlights of the Technical Report

• The operating life at San Bartolomé is extended by 4.6 years based on new 2P mineral reserve

estimate.

• The Technical Report considers only a portion of the Company’s third-party long-term contracts

where sufficient data was available, and excludes feedstock purchased from small independent

third-party miners in Bolivia with whom the Company does not have long-term contracts.

• As of the end of the first nine months ending September 30, 2023, third -party material

represented more than 60% of tonnes processed at San Bartolomé and nearly 70% of ounces

produced.

• Economic grade fines deposit facility (“FDF”) tailings are expected to fully replace pallaco

deposits from the flanks of the Cerro Ricco commencing in Q2 2024 and represent

approximately 11% of San Bartolomé’s 2024 silver production.

• San Bartolomé has been in operation since 2008 and requires US$6.7 million to enable the

hydraulic mining of the FDF tailings, which is anticipated to commence in the first half of 2024.

• The Company’s existing processing plant in Bolivia can run both high-grade silver contracted

material and FDF tailings.

• Future opportunities identified in the Technical Report:

̶ San Bartolome plant is one of the only operations that actively acquires and processes

oxide mineral not suitable for typical flotation plants in Bolivia.

̶ Tollojchi, Altavista, and Paca deposits remain open with potential to increase mineral

resources.

̶ Current tests of oxygen injection are targeting better FDF tailings recoveries.

Annual Mine Plan Summary

The following table includes contracted material from Tollojchi, Altavista, and Paca deposits and

FDF tailings and excludes uncontracted material from independent third -party contractors. (For

Capital and Operating Costs

Life of Mine Capital Cost Summary

Andean estimated the capital costs for the San Bartolomé project. The estimate is based on

historic costs incurred at the site, existing contracts with service providers and engineering to

prepare for the planned FDF expansion. Andean provided SRK with the details supporting their

capital estimates. The table below summarizes the capital cost estimate:

Sustaining Capex Unit Value

FDF hydraulic mining and pre-concentration US$ 6,700,000

Sustaining capital US$ 11,200,000

Closure US$ 2,250,000

Total US$ 20,150,000
