Mineros S.A. Recognized in the 2025 TSX30® Ranking and as a Top Performer on the Colombian Stock Exchange

MEDELLÍN, Colombia--(BUSINESS WIRE)--Mineros S.A. (TSX:MSA, OTCQX:MNSAF, BVC:MINEROS) (“Mineros” or the “Company) announces its inclusion in the 2025 TSX30®, an annual ranking of the 30 top-performing issuers on the Toronto Stock Exchange (“TSX”). The ranking is based on dividend-adjusted share price appreciation over a three-year period.

Daniel Henao, President and Chief Executive Officer, commented, "Our inclusion in the TSX30® Ranking is a powerful validation of our execution and strategic roadmap. By outperforming 98% of the public companies listed on the TSX and leading the market in Colombia, Mineros has demonstrated a unique capacity for value creation. This milestone is a testament to our team’s execution, and we remain focused on maintaining this momentum as we scale our operations."

Mineros is also the top-performing equity on the Colombian Stock Exchange (“BVC”) for the second consecutive year. From January 2, 2024, to December 31, 2025, Mineros generated a 903% total return in U.S. dollar terms, compared with a 186% increase in the VanEck Gold Miners ETF and a 110% increase in the gold price.

Despite this sustained outperformance, management believes Mineros remains undervalued relative to regional peers across several market metrics, including price-to-net-asset-value (P/NAV) and enterprise value (“EV”) per 100,000 ounces of production. Based on published 2025 gold-equivalent production of approximately 226,000 ounces, Mineros trades at an enterprise value of approximately US$637 million per 100,000 ounces of production, compared with an average of approximately US$1,772 million per 100,000 ounces for a representative group of Latin American gold producers.

The TSX30® program recognizes TSX-listed companies that rank in the top 2% of performance over a three-year period and serves as a benchmark for sustained growth. Mineros’ inclusion highlights the effectiveness of its operating strategy and capital discipline. Recognition across both North American and South American capital markets further reflects the Company’s strengthening market profile and liquidity.
