Atico Mining Announces Q3 Operating Results For Its El Roble Mine In Chocó, Colombia

Atico Mining Corporation (TSX.V: ATY | OTC: ATCMF) announces its operating results for the three months ended September 30, 2020 from its El Roble mine. Production for the quarter totaled 5.55 million pounds of copper and 2,487 ounces of gold in concentrates, a decrease of 3% for copper and 25% for gold over the same period in 2019.

“The production results for the quarter were mostly in line with our 2020 objectives while the mine continued to operate under strict preventative protocols and health policies. The decrease in gold production is mainly driven by a lower head grade, expected in the mine plan for the quarter while operations still remain on track for record revenues in the second half of the year” said Fernando E. Ganoza, CEO. “We will continue operating with the highest health and safety standards during these unprecedented times, while at the same time keeping a focus on delivering our 2020 production guidance.”

Third Quarter Operational Highlights

• Production of 5.55 million pounds of copper contained in concentrates; a decrease of 3% over Q3 2019.
• Production of 2,487 ounces of gold contained in concentrates; a decrease of 25% over Q3 2019.
• Average processed tons per day of 860, no significant change over Q3 2019.
• Copper head grade of 3.74%, an increase of 2% over Q3 2019.
• Gold head grade of 1.87 grams per ton; a decrease of 20% over Q3 2019.
• Copper and gold recovery of 91.4% and 56.3%; an increase of 2% for copper and a decrease of 25% for gold over Q3 2019.

Third Quarter Operational Review

Overall production was mostly in line with company budget for the third quarter. The decrease in gold head grade and production is primarily explained by the mine plan for the quarter and to a lesser extent by the lower than anticipated gold recovery. The operation remains on track to deliver on set guidance throughout the remainder of the year.

Atico Mining 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 tons 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 tons 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 tons per day.

El Roble has Proven and Probable reserves of 1.47 million tons grading 3.40% copper and 1.88 g/t gold, at a cut-off grade of 1.93% copper equivalent as of June 30^th, 2018. 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.
