MEDELLÍN, Colombia--(BUSINESS WIRE)--June 9, 2025--Mineros S.A. (TSX: MSA,

MINEROS: CB) (“Mineros” or the “Company”) is pleased to announce that over the past seven

years, Mineros has invested more than US$12 million (COP $50.000M) in social impact

projects, benefiting more than 80,000 people in Bajo Cauca, Antioquia. This was accomplished

through the Works for Taxes program, through which individuals and legal entity taxpayers may

pay income and other taxes by investing in public works or projects of social importance that

meet the legal requirements in Zones Most Affected by Armed Conflict (ZOMAC).

Projects completed and close to completion:

 Escarralao - El Bagre Road

Beneficiaries: Improved connectivity between towns for close to 80,000 inhabitants of Zaragoza

and El Bagre which strengthened the social and economic environment in these communities.

 Phase I (2020): Connected Zaragoza and El Bagre with the 4G Troncal de la Paz road.

o Investment: COP $18.650 million

o Length: 5.5 paved kilometers

 Phase II (2021-2022): Constructed the section between Puerto Jobo and Puente de la

Libertad

o Investment: COP $24.881 million

o Length: 5.8 paved kilometers

 Implemented new technologies in urban and rural educational centers in El Bagre, Nechí

and Zaragoza with the dual objectives of improving both teaching and learning processes,

and promoting the educational development of children and young people in the Bajo

Cauca region of Antioquia.

Beneficiaries: 151 educational centers, wherein 492 teachers were trained and 5,869 computers

delivered.

o Investment: nearly COP $14.600 millions

Thanks to the Works for Taxes program, Mineros has consolidated its position as a pioneer in the

use of this mechanism, working jointly with the Government of Antioquia and Proantioquia. In

addition, this work has been carried out in coordination with local, departmental and national

governments, as well as with the National Planning Department and the Land Renewal Agency.

David Londoño, President and Chief Executive Officer of Mineros said: “At Mineros, we are

convinced that our growth must go hand in hand with the well-being and economic and social

progress of our host communities. Works for Taxes allow us, as a Company, to allocate a portion

of our taxes to the direct construction of priority infrastructure and the implementation of social

development projects. Our participation in Works for Taxes ensures that investment reaches

communities efficiently and transparently. It is our way to accelerate closing social gaps and to

build a future with more opportunities for all, especially for children and young people who are

the future of our society.”

As part of its ongoing commitment to the comprehensive development of the regions where it

operates, Mineros is currently advancing eight new projects with a total investment of over

US$48.2 million (COP $200,000 million). Mineros itself has contributed nearly 45% of this

amount, equivalent to US$22.06 million (COP $91,621 million), alongside contributions from

partner companies such as Empresas Púplicas de Medellín, Grupo Nutresa S.A., and Grupo

Argos S.A., among others.

These projects include the improvement of rural and urban roads, the construction of a pedestrian

bridge over the Cauca River, and the development of an educational institution in El Bagre. They

also involve the distribution of books and sports equipment to local communities.

In Nicaragua, Mineros’ wholly owned subsidiary, HEMCO Mineros Nicaragua S.A., has

received the necessary Forest Harvesting Permit to begin construction of its underground mine at

the Porvenir Project. The project is located in the community of Vesubio, within the municipality

of Bonanza, in the North Caribbean Coast Autonomous Region (RACCN) of Nicaragua—a

region with a rich mining tradition.

* Figures are based on the closing COP/USD exchange rate of $4,149 as of May 31, 2025.
