MINEROS REPORTS STRONG FIRST QUARTER 2026 GOLD PRODUCTION OF 60,782 GOLD EQUIVALENT OUNCES, DELIVERING 10% YEAR-OVER-YEAR GROWTH

Mineros S.A. has released its production results for the three months ended March 31, 2026 (Q1 (first quarter) 2026).

Q1 2026 production highlights:

• Total gold production: 57,850 ounces, representing a 7-per-cent increase compared with Q1 2025;
• Total silver production: 161,766 ounces, representing a 109-per-cent increase compared with Q1 2025;
• Gold equivalent (AuEq) (1) production: 60,782 ounces, a 10-per-cent increase over the 55,124 ounces produced in the same period last year;
• Operational outperformance: significant growth driven by the Hemco property in Nicaragua, which saw a 22-per-cent year-over-year increase in gold production;
• Process optimization: improvements attributed to higher gold and silver recovery rates and strategic plant capacity expansions.

Operational review

The company's strong Q1 2026 performance was primarily driven by strategic initiatives at its Nicaraguan operations. By focusing on metallurgical recoveries and expanding throughput, the Hemco operation delivered meaningful year-over-year production growth.

At the Nechi property in Colombia, first quarter production of 19,909 ounces is slightly lower than average but in alignment with the mining plans. Recovery to normal production levels is expected in Q3 (third quarter) 2026 as the company advances to the following areas. In parallel, the company is advancing continuous improvements to production rate and metallurgical recovery through disciplined operational execution, while formalizing additional partner operational units.

Daniel Henao, president and chief executive officer of Mineros, commented: "The first quarter results are encouraging. Silver production at Hemco more than doubled year over year to 161,766 ounces, reflecting sustained improvements in metallurgical recovery, while gold production at the property increased 22 per cent on the back of disciplined plant optimization. Safety and environmental performance remained integral to how these results were achieved.

"Looking ahead, our principal objective for 2026 remains the expansion of Hemco's processing capacity to 2,500 tonnes per day by year-end. Throughput has already reached 2,100 tonnes per day, building on the 2,000 tpd reported in March. With over 60,000 gold equivalent ounces produced in the quarter, the company is tracking toward the upper end of annual guidance of 213,000 to 233,000 ounces."

Election of directors -- electoral quotient system

The company has secured an exemption from the individual voting and majority voting requirements generally applicable to listed issuers under Toronto Stock Exchange policies. This exemption is granted on the grounds that compliance with such requirements would constitute a breach of binding Colombian laws and regulations, which mandate that directors be elected on the basis of a slate of nominees proposed for election pursuant to an electoral quotient system. Comprehensive information is available in the company's most recent annual information form, which can be accessed via the company's website and on SEDAR+.

(1) Gold equivalent (AuEq) has been calculated based on silver production of the quarter multiplied by the average realized price per ounce of silver sold and divided by the average realized price per ounce of gold sold for the respective period. Silver is treated as a byproduct and represents a minor portion of consolidated output; guidance for silver production is not provided.
