Atico Mining Corporation (the "Company" or "Atico") (TSX.V: ATY | OTCQX: ATCMF) announces its operating results for the three months ended September 30, 2021 from its El Roble mine. Production for the quarter totaled 4.43 million pounds of copper and 2,952 ounces of gold in concentrates, a decrease of 20% for copper and an increase of 19% for gold over the same period in 2020.

"The production results for the quarter, particularly for copper were slightly below our 2021 objectives while the mined and processed tonnes are back on track after a challenging first half of the year. The decrease in copper is mainly driven by a lower head grade, partially expected in the mine plan for the period although expected to improve in the last quarter of the year," said Fernando E. Ganoza, CEO. "We will continue looking for opportunities to improve metal production in the fourth quarter, with the primary goal of delivering our 2021 production guidance while operations still remain on track for record revenues in the second half of the year."

Third Quarter Operational Highlights

  • Production of 4.43 million pounds of copper contained in concentrates; a decrease of 20% over Q3 2020.
  • Production of 2,952 ounces of gold contained in concentrates; an increase of 19% over Q3 2020.
  • Average processed tonnes per day of 919, an increase of 7% over Q3 2020.
  • Copper head grade of 2.77%, a decrease of 26% over Q3 2020.
  • Gold head grade of 1.98 grams per tonne; an increase of 2% over Q3 2020.
  • Copper and gold recovery of 93.2% and 59.7%; an increase of 2% and 6% for copper and gold, respectively over Q3 2020.

Third Quarter Operational Review

Overall production was in line with Company budget for the third quarter. The decrease in copper production is mainly explained by the decrease in head grade, partially offset by improved recoveries and an increase in processed tonnes over the same period last year. The gold output slightly improved due to an improvement in gold head grade, recovery and an increase in processed tonnes relative to Q3-2020. The inverse relationship between copper and gold head grades production during this period is explained by the current mining sequence of the orebody. During this period last year, we were mining higher grade base metal areas which typically have lower precious metal content, while during this period we mined lower base metal grade areas with higher precious metal content.

The Company continues to closely monitor developments around the COVID-19 pandemic and continues to maintain strict preventative measures at the El Roble mine site, La Plata project, as well as our corporate offices to safeguard the health of its employees, while continuing to operate effectively and responsibly in its communities.

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 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.
