Atico Mining Corporation (the “Company” or “Atico”) (TSX.V: ATY | OTCQX: ATCMF) announces its operating results for the three months ended March 31, 2022 from its El Roble mine.

“At the El Roble mine, we had an exceptional quarter compared to our forecast and to the same period last year. In some areas of the mine, we had much higher copper and gold grades than expected,” said Fernando E. Ganoza, CEO. . “We will continue to build on the operational success of this quarter to make up lost production in April, looking to take advantage of the current high metal price environment. In parallel, considerable emphasis will be placed on drilling near the mine in an effort to find additional resources.”

First Quarter Operational Highlights

  • Production of 4.82 million pounds of copper contained in concentrates; an increase of 7% compared to Q1 2021.
  • Production of 2,636 ounces of gold contained in concentrates; an increase of 24% compared to Q1 2021.
  • Average tonnes handled per day of 826, down 13% from Q1 2021.
  • Copper head grade of 3.55%, a 10% increase over Q1 2021.

First quarter operational review

Copper and gold production was above the company’s budget for the first quarter, primarily due to higher copper and gold head grades. Copper recoveries decreased slightly compared to the same period last year, while gold recoveries in the quarter improved compared to the Company’s projections. The number of tons processed per day decreased compared to the same period last year, mainly due to the commissioning of recently installed equipment. For the quarter, the operation exceeded budget in almost all metrics.

Mine El Roble

The El Roble mine is an underground high-grade copper and gold mine with a nominal processing plant capacity of 1,000 tonnes per day, located in the Choco department of Colombia. Its commercial product is a copper-gold concentrate.

Since gaining control of the mine on November 22, 2013, Atico has improved the operation from a historical design 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 and 2020. The mineralization is open at depth and laterally and the Company plans to further test the limits of the deposit.

On the largest body of land, the Company has identified a prospective stratigraphic contact between volcanic rocks and black and gray pelagic sediments and cherts that has been traced by Atico geologists for ten kilometers. This contact was determined to be an important check on the VMS mineralization over which Atico has identified numerous potential target areas for the occurrence of VMS-type mineralization, which is the focus of the current surface drilling program at El Roble.
