Medellín, Colombia – January 7, 2026

With a trajectory defined by commitment, trust, and collective action, the Mineros Foundation celebrates 15 years of uninterrupted work. It has established itself as a benchmark for how coordination between the private sector, the community, and the State generates a sustainable and lasting impact on the territory.

Throughout these years of management, the Mineros Foundation has intervened in seven municipalities across the Bajo Cauca and Northeast regions of Antioquia. More than 59,000 people have participated in 54 social initiatives under an intervention model that integrates Education, Culture, Peace and Healthy Coexistence, and Inclusive Economy. These results not only strengthen the regional social fabric but also align with the United Nations Sustainable Development Goals (SDGs).

This journey has been made possible thanks to the trust of the communities and the power of 35 strategic alliances. These include national and international public and private actors such as the Government of Antioquia, Fundación Bancolombia, Fundación Unibán, Comfama, Comfenalco, Postobón, Corantioquia, Fútbol con Corazón, and Interactuar, among others.

“We celebrate 15 years of contributing to the social fabric and the sustainable development of the region. The Mineros Foundation has been an engine that drives rural education, promotes equity, transforms physical infrastructure through various territorial impact projects, and strengthens the local economy with an inclusive focus. This path has been possible thanks to the trust of the communities and the power of partnerships. We remain committed to a more equitable territory full of opportunities,” stated Santiago Cardona, Country Manager of Mineros.

During the past year, the Foundation's social investment reached $4,463 million COP, integrating into the country's social ecosystem through the Association of Family and Corporate Foundations (AFE) and projecting its commitment toward global sustainability stages.

Key Initiatives

Among the most outstanding initiatives are programs such as:

• Líderes de Oro Scholarships: Since 2019, this program has provided 70 young people with access to higher education.
• Rural Education in Antioquia: This initiative has transformed teaching in 116 educational sites using methodologies adapted to rural contexts.
• “Escuelas para la Vida” (Schools for Life): In partnership with Corantioquia, this program promotes environmental education in 15 rural locations.

Furthermore, cultural and musical programs like Batuta, Iberacademy, and El Nido del Bajo Cauca stand out, involving more than 400 children and strengthening processes of identity, creativity, and healthy coexistence.

The Mineros Foundation also promotes inclusive economy projects, such as:

• Asoagrollana: Promoting economic autonomy and the sustainability of aquaculture practices.
• Asapibas (Beekeepers Association of Bajo Cauca and Southern Bolívar): This association currently supports and strengthens the work of beekeeping families, consolidating a sustainable and transformative economic alternative in honey production that now engages with national and international markets.

For Mineros, celebrating 15 years represents a reaffirmation of its commitment to a territory full of opportunities, proving that responsible mining acts as a fundamental driver for collective well-being.
