VANCOUVER, BRITISH COLUMBIA--(Marketwired - Apr 19, 2016) - Atico Mining Corp. (the "Company" or "Atico") (TSX VENTURE:ATY)(OTC PINK:ATCMF) announces its operating results for the three months ended March 31, 2016 from its El Roble mine. Production for the quarter totaled 4.28 million pounds of copper and 2,566 ounces of gold in concentrates, an increase of 114% for copper and 12% for gold over the same period in 2015.

"We are very pleased to report the Company has had another strong operating quarter reaching historical highs for processed ore and produced copper." said Fernando E. Ganoza, CEO. "Along with robust operating results the Company has made two concentrate shipments during the quarter that will be reflected in the first quarter financial results. We will continue to optimize the mine in the subsequent quarters and focus on delivering on our 2016 guidance."

First Quarter Operational Highlights

• Production of 4.28 million pounds of copper contained in concentrates; an increase of 114% over Q1 2015.
• Production of 2,566 ounces of gold contained in concentrates; an increase of 12% over Q1 2015.
• Average processed tonnes per day of 778, an increase of 40% over Q1 2015.
• Copper head grade of 3.81%, an increase of 31% over Q1 2015.
• Gold head grade 2.25 grams per tonne; a decrease of 28% over Q1 2015.
• Copper and gold recovery of 94.4% and 67.2%; an increase of 1% for copper and no significant change for gold over Q1 2015.

First Quarter Operational Review

Optimization of the operation continued throughout the first quarter with positive results in increasing the daily throughput and mill capacity. Copper recovery has continued to improve quarter over quarter maintaining historical highs, while gold recovery still shows opportunity for further improvements. We plan to capitalize on these opportunities in gold recovery throughout the year by focusing on commissioning of newly installed equipment. The operation saw its highest throughput average to date while the current production schedule continues on track for the operation to deliver on 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 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 31,377 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 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 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.
