Atico Reports 2025 Fourth Quarter and Full Year Production Results

VANCOUVER, British Columbia, Jan. 22, 2026 (GLOBE NEWSWIRE) -- Atico Mining Corporation (the “Company” or “Atico”) (TSX.V: ATY | OTCID: ATCMF) is pleased to announce operating results for the three months and year ended December 31, 2025 from its El Roble mine. Production totaled 2.6 million pounds of copper with 2,203 ounces of gold for the fourth quarter (“Q4 2025”) and 9.2 million pounds of copper with 8,013 ounces of gold in concentrates for the full year of 2025.

“During 2025 El Roble went through a transitional year migrating to the upper parts of the mine where the additional reserves have been identified. Production during the year reflected the challenges faced during development and preparation of the new reserves but also advancements as every quarter more stopes in the upper part came online. In the fourth quarter we showed the best results of the year, helping achieve the updated production guidance across most key metrics. In 2026, we expect to deliver continued quarterly improvements in performance, as we complete the extraction of lower-grade reserves from the lower sections of the mine. We anticipate an important year-over-year increase in overall metal production, well timed to capitalize on the prevailing strong metal price environment," said Fernando E. Ganoza, CEO. “Looking ahead, several important milestones remain on the horizon. At El Roble, we intend to dedicate substantial resources to in-mine and near-mine drilling to further delineate the deposit and identify additional mineralization in the surrounding area where we see opportunity to continue extending the life-of-mine. At the La Plata project in Ecuador, we continue pressing forward with efforts to complete the permitting process, targeting a positive construction decision in Q2-Q3 of this year."

El Roble Mine

The El Roble mine is a high grade, underground copper and gold mine with nominal processing plant capacity of 1,000 tonnes per day, located in the Department of Choco in Colombia. Its commercial product is a copper-gold concentrate.

Since obtaining control of the mine on November 22, 2013, Atico has upgraded the operation from a historical nominal capacity of 400 tonnes per day.

El Roble’s reserves estimate, with an effective date of March 12, 2024, includes Proven and Probable mineral reserves of 828 thousand tonnes averaging 2.49% Cu, 2.20 g/t Au and a life of mine until Q1-2027. A full NI 43-101 technical report is available on SEDAR+.  For more information on the reserves estimate refer to SEDAR+ and on the Company’s website.

Mineralization is open at depth and along strike and the Company plans to further test the limits of the deposit. On the larger land package, the Company has identified a prospective stratigraphic contact between volcanic rocks and black and grey pelagic sediments and cherts that has been traced by Atico geologists for ten kilometers. This contact has been determined to be an important control on VMS mineralization on which Atico has identified numerous target areas prospective for VMS type mineralization occurrence, which is the focus of the current surface drill program at El Roble.
