Atico Produces 5.15 Million Pounds of Cu and 2,570 Ounces of Au in Second

Quarter 2017

Vancouver, July 18, 2017 -- Atico Mining Corporation (the “Company” or “Atico”) (TSX.V:

ATY | OTC: 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 please d 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 recover y 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 Q 2-2016 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 projection s. Gold recovery decreased sli ghtly as expected

driven by a 10% increase in the copper content in the concentrate to 2 2.34% (20.30% in Q 2-

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 quarte rs while increasing the

gold recovery.

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 co ntact 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.
