Atico Reports High Grade Intercepts up to 4.45m of 5.17% Cu, 10.47g/t Au and 4.90m of 9.35% Cu, 2.94 g/t Au and Continues to Extend the Ore Body at El Roble Mine in Colombia

VANCOUVER, British Columbia, Feb. 05, 2024 (GLOBE NEWSWIRE) -- Atico Mining Corporation (TSX.V: ATY | OTCQX: ATCMF) (“Atico” or the “Company”) is pleased to announce additional positive results for the exploration program initiated in 2023 being carried out in an area of historical mining to expand tonnage at the El Roble mine. In addition, the Company reports the results for seven diamond drill core holes (see first table below), which included 4.45m of 5.17% Cu, 10.47g/t Au and 4.90m of 9.35% Cu, 2.94 g/t Au.

“We are pleased to report that our mine vicinity drill campaign continues to intercept new mineralization and extend the main historic massive sulphide body at the El Roble deposit. While, this area was mined by operators previous to Atico obtaining control of the mine on November 22, 2013, these results are intercepting additional high-grade mineralization beyond the previously outlined mineralized shell which remains open at depth and along strike,” said Fernando E. Ganoza, CEO. “These strong assay results continue to increase confidence in our view that additional high-grade copper and gold mineralization remains both within the historically defined bodies and beyond the previously outlined mineralized shell and are open at depth and along strike. Final results for the remaining drill holes from the current exploration program initiated in 2023 will be available within following weeks at which time the Company plans to update the resource estimate. A new drill program is planned to continue exploration in this vicinity during 2024.”

True widths are dependent on uncertainties in the local strike and dip of the mineralization and are estimated to be between 90% and 95% of the drill intercept.
