VANCOUVER, BRITISH COLUMBIA–(Marketwired – July 18, 2017) – Atico Mining Corporation (the “Company” or “Atico”) (TSX VENTURE:ATY)(OTC PINK:ATCMF) announces its operating results for the three months ended June 30, 2017 from its El Roble mine. Production for the quarter totaled 5.15 million pounds of copper and 2,570 ounces of gold in concentrates, an increase of 8% for copper and a decrease of 13% for gold over the same period in 2016.

“We are very pleased to report a strong operating quarter maintaining steady state production levels and remaining in line to reach operational objectives for 2017.” said Fernando E. Ganoza, CEO. “For the remainder of the year, the Company will continue focusing on the regional and mine vicinity exploration programs with four rigs currently drilling on surface and underground.”

Second Quarter Operational Highlights

• Production of 5.15 million pounds of copper contained in concentrates; an increase of 8% over Q2 2016.
• Production of 2,570 ounces of gold contained in concentrates; a decrease of 13% over Q2 2016.
• Average processed tonnes per day of 794, a decrease of 3% over Q2 2016.
• Copper head grade of 3.94%, an increase of 9% over Q2 2016.
• Gold head grade of 2.07 grams per tonne; a decrease of 6% over Q2 2016.
• Copper and gold recovery of 94.4% and 61.8%; an increase of 2% for copper and a decrease of 5% for gold over Q2 2016.

Second Quarter Operational Review

Processed ore was in line with Company budget for the second quarter. The increase in higher copper output for the quarter relative to Q2-2016 is explained by a higher copper head grade and an increase in copper recovery. In the case for gold production, a planned lower head grade and a decrease in the gold recovery resulted in lower gold output over Q2-2016.
Copper recoveries were higher than the same period last year, while gold recoveries during the quarter were in line with Company projections. Gold recovery decreased slightly as expected driven by a 10% increase in the copper content in the concentrate to 22.34% (20.30% in Q2-2016). This increase in the copper content in the concentrate provides a net economic benefit offsetting the resulting decrease in gold recovery. The Company will continue to explore increasing the copper content in the concentrate in the following quarters while increasing the gold recovery.

The operation remains on track to deliver on set guidance throughout the remainder of the year.

El Roble Mine

The El Roble mine is a high grade, underground copper and gold mine with nominal processing plant capacity of 800 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 a measured and indicated resource of 1.87 million tonnes grading 3.46% copper and 2.27 g/t gold, at a cut-off grade of 0.93% copper equivalent. Mineralization is open at depth and along strike and the Company plans to further test the limits of the resource.

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.
