Atico Intercepts 116m of 5.61% Cu and 1.99g/t Au and 35m of 7.10% Cu and 8.94g/t Au at El Roble Mine in Colombia

  Vancouver, June 23, 2015 - Atico Mining Corporation (TSX.V: ATY | OTC: ATCMF)("Atico" or the "Company") is pleased to announce that ongoing infill drilling at the El Roble mine continues to extend mineralization at Zeus, approximately perpendicular to the strike direction of the massive sulfide body. In addition, the Company reports the results for five diamond drill core holes (ATD-0010 through ATD-0014), which included 116m of 5.61% copper and 1.99g/t gold and 35m of 7.10% copper and 8.94g/t gold, respectively.

Fernando E. Ganoza, CEO, commented: "We are pleased to report yet another successful batch of drill results where the infill drilling at El Roble continued to intercept high grade mineralization at the Zeus-Aquiles-Ares massive sulfide body beyond the previously outlined mineralized shell. These results continue to increase confidence in our view that mineralization remains strong and open at depth. We plan to continue the drill program at the mine well into the second half of the year at which time the Company plans to update the resource estimate." Mr. Ganoza added, "with the continued success of the ongoing drill program and the extension of mineralization at depth and along strike, management has initiated evaluating potential scenarios for a subsequent scale-up of the El Roble mill."

Infill Drilling Program

The goal of the current underground drilling program at the El Roble mine is to further define the known mineralized bodies and expand the identified resource. During the fourth quarter of 2014, the Company began a drill program to specifically test the Zeus, Aquiles and Ares mineralized bodies. Infill drilling approximately perpendicular to the strike direction of the known massive sulfide bodies (318 degrees average strike, 85 degrees east average dip) and drilling of new prospective areas below the 2000-meter level is being conducted from the new main level 1880 adit. Subsequent to the six holes of the program (ATD-0004 to ATD-0009) where drilling significantly extended mineralization at Zeus and Aquiles as reported in May 2015 (See Atico news release dated May 6th, 2015), the Company is reporting the next batch of five drill holes (ATD-0010 to ATD-0014). Infill hole ATD-0013 intercepted a completely new area of mineralization significantly extending the massive sulfide body along strike to the south and to the west. Infill hole ATD-0014 intercepted a significantly larger interval of massive sulfide than had been modeled in the National Instrument 43-101 inferred resource estimate wireframes of Zeus, Aquiles and Ares (See Atico technical report dated August 27, 2013).

Figure 1 clearly shows the strong mineralized infill intervals between the Aquiles and Ares mineralized bodies relative to previous drilling and to the west of the Zeus mineralized body. The mineralization remains open to south west and at depth.

El Roble Mine

The El Roble mine is a high grade underground copper and gold mine with nominal processing plant capacity of 650 tpd, 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.

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.

Quality Assurance & Quality Control

Following detailed geological and geotechnical logging, drill core samples are split on-site with a diamond saw by Atico personnel. The 7 to 10 kilograms per meter of sample are submitted to the ALS Chemex laboratory in Medellin where they are dried, crushed and pulverized. After preparation, the samples are sent to ALS Chemex in Lima and assayed. The remaining half core sample is retained on- site for verification and reference purposes. All gold assays were obtained by standard 50 gram fire assay with AA finish. All copper and silver assays reported were obtained by aqua-regia sample dissolution of the sample followed by ICP analysis. The QA-QC program includes the blind insertion of certified reference standards as well as assay blanks and duplicates at a frequency of approximately one per 15 samples.
