VANCOUVER, British Columbia, Jan. 17, 2024 (GLOBE NEWSWIRE) -- Atico Mining Corporation (the "Company" or "Atico") (TSX.V: ATY | OTCQX: ATCMF) is pleased to
announce operating results for the three- and twelve-month periods ended December 31, 2023 from its El Roble mine. Production totaled 4.37 million pounds
of copper with 2,578 ounces of gold for the fourth quarter ("Q4 2023") and 13.24 million pounds of copper with 10,149 ounces of gold in concentrates for the full year 2023.
"Operationally the Company had a challenging first half of the year. The team turned things around in the third quarter and continued to improve all metrics to finish the year delivering just under our production guidance. At the same time, we saw very prospective drill results from our El Roble mine vicinity drill program which could point towards an extension of the current life of mine," said Fernando E. Ganoza, CEO. "In the upcoming year, we continue to have significant milestones ahead of us yet to achieve. In the first half of the new year, our main focus will be on the El Roble mine resource update, completion of
the La Plata Feasibility Study and delivering on all requirements to receive the
environmental permit for the La Plata project."

an inherent variability in tonnes shipped quarter to quarter.

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 has Proven and Probable reserves of 1.00 million tonnes grading 3.02%
copper and 1.76 g/t gold, at a cut-off grade of 1.3% copper equivalent with an effective date of September 30, 2020. 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.
