Atico Mining Corporation (TSX-V: ATY) (OTCQX: ATCMF) is pleased to announce operating results for the three and twelve month periods ended December 31, 2021 from its El Roble mine. Production totaled 4.93 million pounds of copper with 3,152 ounces of gold for the fourth quarter and 18.07 million pounds of copper with 11,016 ounces of gold in concentrates for the full year 2021.

“2021 was a challenging year where the operations team had to navigate through strict health and safety protocols caused by the global pandemic while also facing tough weather conditions in the first half of the year. Despite these challenges, we came very close to deliver on our production guidance. Copper production came just under budget mostly explained by a decline in head grade, while gold production was at the high end of our guidance. We are still anticipating that these results will lead to strong revenues for the fourth quarter and robust financials for year-end 2021,” said Fernando E. Ganoza, CEO. “In the upcoming year, we will continue moving towards getting the La Plata Feasibility Study across the finish line while also aggressively exploring both El Roble and La Plata properties as well as working towards achieving operational guidance for 2022.”

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.
