Atico Produces 2.9 Million Pounds of Cu and 2,298 Ounces of Au in Second Quarter 2015

VANCOUVER, BRITISH COLUMBIA--(Jul 14, 2015) - Atico Mining Corporation (the "Company" or "Atico") (TSX VENTURE:ATY)(OTC PINK:ATCMF) announces its operating results for the three months ended June 30, 2015 from its El Roble mine. Production for the quarter totaled 2.9 million pounds of copper and 2,298 ounces of gold in concentrates, an increase of 41% and 7% respectively for copper and gold over the same period in 2014.

"In the second quarter 2015 we delivered a significant improvement over the same period last year and results just slightly below our expectations despite facing extreme weather conditions and flooding in the region," said Fernando E. Ganoza, CEO. "In the latter half of June we experienced improved weather conditions and a strong conclusion to the quarter. We remain optimistic that we will be able to operate the mill at current capacity of 650 tonnes per day throughout the remainder of the year."

Second Quarter Operational Highlights

• Production of 2.9 million pounds of copper contained in concentrates; an increase of 41% over Q2 2014.
• Production of 2,298 ounces of gold contained in concentrates; an increase of 7% over Q2 2014.
• Average processed tonnes per day of 576, an increase of 31% over Q2 2014.
• Copper head grade of 3.45%, an increase of 12% over Q2 2014.
• Gold head grade 2.65 grams per tonne; a decrease of 15% over Q2 2014.
• Copper and gold recovery of 93.7% and 66.1%; an increase of 4% for copper and gold respectively over Q2 2014.

Second Quarter Operational Review

Throughout most of the quarter the Company continued to optimize the newly commissioned equipment. At the plant, the highest copper recovery to date was achieved with the opportunity for further improvements for gold recovery remaining. In addition, the overall operation saw its highest daily throughput average for a quarter since the Company's acquisition of the mine. The current plan in place calls for the operation to make up for most of the production shortfall throughout the remainder of the year.

Second Quarter Operational Details

El Roble Mine

The El Roble mine is a high grade underground copper and gold mine with nominal processing plant capacity of 650 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 nominal capacity of 400 tonnes per day. The mine has a continuous operating history of twenty two years, with recorded production of 1.5 million tonnes of ore at an average head grade of 2.6% copper and an estimated gold grade of 2.5 g/t. Copper and gold mineralization at the El Roble property occurs in volcanogenic massive sulfide ("VMS") lenses.

Since entering into the option agreement in January 2011 to acquire 90% of El Roble, Atico has aggressively explored the mine and surrounding claims. The Company has completed 11,740 meters of diamond drilling and identified numerous prospective targets for VMS deposits on the 6,679-hectare property. This exploration led to the discovery of high-grade copper and gold mineralization below the 2000 level, the lowest production level of the El Roble mine. Atico has developed a new adit access from the 1880 elevation to develop these new resources.

El Roble has an inferred mineral resource of 1.58 million tonnes grading 4.45% copper and 3.17 g/t gold, at a cut-off grade of 0.72% copper equivalent (See Atico technical report dated August 27, 2013). 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 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 15 prospective target areas for VMS type mineralization occurrence, which is the focus of the surface drill program at El Roble.
