• Production of 2,948 ounces of gold contained in concentrates; an increase of 28% over Q2 2015.

• Copper and gold recovery of 93% and 65.8%; no significant change for copper and gold over Q2 2015.

Second Quarter Operational Review

Operation for the quarter has continued to reach new production levels as it stays in line with our budgets and guidance for the year. Copper recovery has continued maintaining recently reached highs, while gold recovery still shows opportunity for further improvements. The team on site will continue to optimize the operation through the remainder of this year to capitalize on remaining opportunities particularity in gold recovery.

Despite having a record quarter in concentrate production, the Company only delivered one of the two concentrate shipments scheduled for this quarter due to the national transportation union strike in Colombia. The Company anticipates that this interruption will result in higher ending concentrate inventory and lower sales for the quarter, as revenue from the second scheduled shipment will be recognized in the third quarter.

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.
