Medellín, June 9, 2026 - In a milestone for responsible mining in Colombia, Mineros has established itself as the pioneer and leading company in the execution of the Works for Taxes (OxI) mechanism. Between 2018 and 2026, the Company has invested, together with partners, a total of $117,14 million, of which $54,99 million correspondto direct contributions from Mineros, transforming the social reality of the most underserved subregions.
On May 14, the Agency for Territorial Renewal (ART) issued the resolutions that cleared the way for a new batch of 10 projects. Of the total budget approved by the National Government, Mineros and its partners will participate with a combined investment of $46,54 million, of which Mineros will directly contribute $13,31 million. With this step, the Company not only reinforces its presence in Antioquia, but also extends into other areas such as the department of Tolima, contributing to the country’s development and the well-being of communities.
This achievement is also the result of the drive provided by the Government of Antioquia and the coordination of the Proantioquia OxI Platform, which serves as the technical and strategic bridge between the private and public sectors. This coordination model is already a national benchmark and is currently being replicated in departments such as Norte de Santander, Caquetá, La Guajira, Chocó, Bolívar, and Caldas.
“Public-private coordination is the most powerful tool for closing social gaps. For Mineros, this mechanism goes beyond taxation: it is a commitment to the sustainability of the territory. When the State and the private sector align their objectives to build a school or pave a road, we are turning the wealth of the subsoil into tangible social progress and real opportunities for the subregions of Colombia”, said Daniel Henao, CEO of Mineros.
The work is organized around four strategic fronts: drinking water and basic sanitation, education and early childhood, rural road improvement, and public health. Under this roadmap, a series of key projects will be launched to close social gaps in the most underserved territories.
In terms of basic services, two aqueducts will be built in the villages of Bijagual and Cargueros, in Nechí. In parallel, the investment in knowledge will include the delivery of educational materials in the Nordeste and Bajo Cauca subregions of Antioquia, complemented by the construction of two Early Childhood Care Centers in Caicedo and San Luis.
Rural connectivity is also a priority in this initiative; road improvement works will be carried out in the municipalities of San Carlos, San Rafael, and Anorí, in addition to the construction of a concrete trail path in the municipality of Santa Isabel (Tolima). Finally, in an effort to strengthen healthcare services, 21 hospitals in Antioquia’s public network will be equipped with state-of-the-art biomedical devices, optimizing response capacity across an equal number of municipalities.
It is important to note that the Works for Taxes mechanism was established by Law 1819 of 2016 and allows contributing companies to allocate up to 50% of their income tax directly to public investment projects in PDET municipalities and areas Most Affected by Armed Conflict (ZOMAC). The Company assumes the management, execution, and risks of the project under the supervision of the National Planning Department and the Agency for Territorial Renewal. The tax obligation is extinguished upon delivery of the completed work.
With these initiatives, Mineros continues to establish itself as a national benchmark, demonstrating that legal and environmentally responsible mining can amplify opportunities in critical sectors. By expanding its reach, the Company reaffirms that its operations are, above all, an engine of well-being that returns shared value to communities through tangible results.
