Mineros Sets Record December Gold Production, Achieves Upper End of Guidance for 2025

MEDELLIN, Colombia--(BUSINESS WIRE)--Mineros S.A. (TSX:MSA, OTCQX:MNSAF, BVC:MINEROS) (“Mineros” or the “Company”) reports that it achieved record December production of 20,667 ounces of gold equivalent (“AuEq”) in Nicaragua, and total production of 225,846 ounces of AuEq, reaching the upper end of guidance for 2025.

The Company’s performance was driven primarily by strong production from its Nicaraguan operations, with improved processing plant throughput, and preferential treatment of higher-grade artisanal ores combined with stable output from its Colombian operations. These results were delivered while maintaining high standards of safety, occupational health, and environmental management.

Daniel Henao, President and Chief Executive Officer of Mineros, commented: “This performance is beginning to reflect the impact of multiple operational improvement initiatives, supported by our continued focus on efficiency and execution. We remain confident in our ability to generate sustainable value for shareholders.”

2025 Full Year and Fourth Quarter Production Highlights:

• Full-year production: 221,656 ounces of gold (top end of guidance).
• Fourth quarter production: 58,644 ounces of gold.

Notes:
1.	Guidance for silver is not provided, as silver is treated as a by-product and represents a small portion of consolidated output.
2.	Gold equivalent (“AuEq”) has been calculated based on the silver production for the full year multiplied by $36.98, being the average realized price per ounce of silver sold in the first nine months of 2025 and divided by $3,220, being the average realized price per ounce of gold sold. Accordingly, 364,888 ounces of silver converted to gold equivalent is equal to 364,888 X $36.98 / $3,220 = 4190

At the Nechí Alluvial Property, gold production of 89,777 ounces was at the upper end of guidance and approximately 9% higher than 2024, reflecting improved equipment availability, enhanced operating efficiency, and optimized production scheduling.

In Nicaragua, total gold production of 131,879 ounces reached the upper end of guidance and set a new monthly production record for the operations. Ongoing initiatives are focused on further and systematically de-bottlenecking the plant to increase capacity and cost efficiencies.

Mineros plans to release its fourth quarter 2025 and full year 2025 financial and operating results on Wednesday, February 18, 2026.

Senior management will host a conference call on Thursday, February 19, 2026, at 9:00 AM Eastern Standard Time (9:00 AM Colombian Standard Time).
