Atico Mining Corporation (TSX-V: ATY | OTCQX: ATCMF) announces its operating results for the three months ended March 31, 2022 from its El Roble mine. Production for the quarter totaled 2.32 million pounds of copper and 2,566 ounces of gold in concentrates, a decrease of 51% and 3% for copper and gold, respectively, over the same period in 2022.

“At the El Roble mine we had a lower than usual copper head grade and output for the quarter as the mine plan called for transitioning through the lower grade areas of the deposit. The team anticipates that the operation will be moving back into higher copper grades during the second quarter and remain in these areas moving forward,” said Fernando E. Ganoza, CEO. “For the remainder of the year, the operation is projected to make up for lower first quarter production and deliver on this year’s set guidance. In parallel, we continue to make progress on the mine vicinity drilling with the goal to find additional reserves and resources.”

Concentrate Inventory

The number of shipments the Company can export in any given quarter depends on several variables some of which the Company does not control, hence there may be 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 as of September 30^th, 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.
