VANCOUVER, British Columbia, July 21, 2022 (GLOBE NEWSWIRE) — Atico Mining Corporation (the “Company” or “Atico”) (TSX.V: ATY | OTCQX: ATCMF) announces its operating results for the three months ended June 30, 2022 from its El Roble mine. Production for the quarter totaled 3.59 million pounds of copper and 2,811 ounces of gold in concentrates, a decrease of 16% for copper and an increase of 4% for gold, over the same period in 2021.

“The El Roble mine delivered well despite having to stop operations for twenty-four days in April. The stoppage was a result of a landslide incident near the dewatering facility, we are very pleased that no injuries resulted from this incident and that damage to equipment was minor. Given the strong start to the year along with good performance during the operating days of this quarter, the Company is already back on track to deliver on guidance for the year” said Fernando E. Ganoza, CEO. “In second half of the year, we will continue our strong focus towards mine vicinity exploration at the El Roble mine, looking to extend mineralization at depth and along strike.”

Second Quarter Operational Highlights

• Production of 3.59 million pounds of copper contained in concentrates; a decrease of 16% over Q2 2021.
• Production of 2,811 ounces of gold contained in concentrates; an increase of 4% over Q2 2021.
• Average processed tonnes per day of 889, no significant change over Q2 2021.
• Copper head grade of 3.17%, an increase of 2% over Q2 2021.
• Gold head grade of 2.47 grams per tonne; an increase of 24% over Q2 2021.
• Copper and gold recovery of 91.4% and 62.9%; no significant change for both copper and gold over Q2 2021.

Second Quarter Operational Review

Overall production was below Company budget for the second quarter, entirely explained by the twenty-four-day stoppage which resulted in less than expected processed tonnes. The decrease in copper production is mainly explained by the decrease in processed ore along with a slight decrease in head grade over the same period last year. The gold output completely offset the lower processed tonnes in the quarter as we saw a significant improvement in head grade relative to Q2-2021. The operation remains on track to deliver on set guidance throughout the remainder of the year.

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.

, 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.
