MINEROS S.A. APPOINTS NEW CHIEF FINANCIAL OFFICER AND CHIEF TECHNICAL ADVISOR

Mineros S.A. has appointed Natalia Correa Martinez as chief financial officer and Michael Doyle as chief technical adviser, both effective today. These appointments reinforce the depth of Mineros' senior leadership team as the company continues to execute its multijurisdictional growth strategy.

"Natalia and Michael each bring exceptional credentials and an extensive familiarity with Mineros and the mining sector. Natalia's experience across capital allocation, M&A, risk management and cross-border transactions gives her the strategic depth and hands-on expertise to ensure that capital is deployed with the rigour and precision that advancing a multijurisdictional project pipeline demands, and to drive operational efficiency and cost discipline across a complex, multicountry operating structure. Michael brings over 45 years of technical and operational leadership across the full mining cycle -- from exploration and reserve estimation through to underground operations and environmental management. His record advancing complex projects, combined with his expertise in feasibility and geotechnical assessment, makes him ideally placed to strengthen our technical platform as we advance our pipeline and evaluate new opportunities across the region. We are very pleased to welcome them both in their new roles," said Daniel Henao, president and chief executive officer of Mineros.

About Mineros S.A.

Mineros is a leading Latin American gold mining company headquartered in Medellin, Colombia. The company operates a diversified portfolio of assets in Colombia and Nicaragua and maintains a pipeline of development and exploration projects across the region, including the La Pepa project in Chile.

Election of directors -- electoral quotient system

The company has received an exemption from the individual and majority voting requirements applicable to Toronto Stock Exchange-listed issuers. Compliance with such requirements would conflict with Colombian laws and regulations, which require directors to be elected from a slate of nominees under an electoral quotient system.
