MEDELLÍN, Colombia — April 24, 2026 — Mineros S.A. (TSX: MSA | OTCQX: MNSAF
| BVC: MINEROS) (“Mineros” or the “Company”) today announced the groundbreaking
of a new public secondary school — Institución Educativa El Bagre — in the
municipality of El Bagre, Antioquia, located within the Company’s Nechí Alluvial
Property operating footprint in the Bajo Cauca region of Colombia.
Management Commentary
“Investing in education in the communities where we operate is fundamental to how we
understand responsible mining,” said Santiago Cardona Múnera, Vice President for
Colombia Operations of Mineros S.A. “The Works-for-Taxes mechanism is one of the
most effective tools available to Colombian corporate taxpayers for closing development
gaps in post-conflict territories. This project — three years in the making — reflects the
power of structured public-private alliances when they are grounded in a long-term
territorial commitment.”
The Institución Educativa El Bagre is one of several community investment initiatives
Mineros is advancing in the Bajo Cauca region in partnership with Proantioquia’s OxI
Platform, the Government of Antioquia, the Municipality of El Bagre, the Agency for
Territorial Renewal (ART), and Colombia’s Ministry of National Education.

The project represents a total investment of approximately COP $38.7 billion
(approximately US$9.1 million at current exchange rates), of which Mineros is the
principal contributor and project manager. EPM, Grupo Argos, and Grupo Nutresa are
participating as strategic co-investors. Upon completion, the new campus will serve
more than 1,080 students. Construction is expected to take approximately 18 months,
during which students will continue classes at alternate facilities to safeguard academic
continuity.
Project Specifications
Built on a 5,667 m² site with approximately 11,000 m² of new infrastructure, the school
will feature modern classrooms, a community-access library, a multi-sport court, an arts
studio, an audiovisual laboratory, and dedicated physics and chemistry laboratories.
The design standard is without precedent for the Bajo Cauca region and aims to deliver
educational conditions comparable to those available in Colombia’s major urban
centres.
Works-for-Taxes: A Tax-Efficient Framework for Community Investment
The project is structured under Colombia’s Obras por Impuestos (“Works-for-Taxes”)
mechanism — a tax instrument that allows qualifying companies to allocate a portion of
their corporate income tax liability to high-impact social infrastructure in PDET
municipalities (Programs for Development with a Territorial Approach, designated under
Colombia’s post-conflict framework). The mechanism converts mandatory tax
expenditure into tangible, measurable community investment within the Company’s
operating jurisdictions, producing a durable social-license dividend at no incremental
after-tax cost.
