Atico Mining Corporation (the "Company" or "Atico") (TSX.V: ATY | OTCID: ATCMF) announces its operating results for the three months ended September 30, 2026 from its El Roble mine. Production for the quarter totaled 2.08 million pounds of copper and 2,472 ounces of gold in concentrates, a decrease of 7% for copper and an increase of 30% for gold, respectively, over the same period in 2025.
We are seeing the planned improvements in quarterly production as we overcome the operational challenges faced during the development and preparation of the higher-grade areas of the mine. Gold grade and recovery were particularly strong this period and gets us closer to our gold guidance production. Higher gold production is also having a meaningful positive impact on our all-in sustaining cash costs, while we also benefit from strong revenue driven by higher metal prices" stated Fernando E. Ganoza, CEO. "We anticipate production for the following quarter will continue to improve driven by higher copper and gold head grades, while at the same time we are advancing the reserves report update where we expect an increase in the life of mine.

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.Â
