ATICO INTERCEPTS 70M OF 6.26% CU AND 1.85G/T AU AND 109M OF 2.11% CU AND 3.79G/T AU AT EL ROBLE MINE IN COLOMBIA
Atico Mining Corp.'s infill drilling in progress at the El Roble mine continues to extend mineralization of the Zeus body, approximately perpendicular to the strike direction of the massive sulphide body. In addition, the company reports the results for six diamond drill core holes (ATD-0004 through ATD-0009), which included 70 metres of 6.26 per cent copper and 1.85 grams per tonne gold, and 109 m of 2.11 per cent copper and 3.79 g/t gold.
Fernando E. Ganoza, chief executive officer, commented: "Infill drilling at El Roble continues to intercept high-grade mineralization at the Zeus massive sulphide body, beyond the previously outlined mineralized shell, adding further confidence to our view that mineralization remains strong and open at depth. The ongoing drill program at the mine will continue well into the second half of the year, at which time the company plans to update the resource estimate." Mr. Ganoza added, "based on the new geological information and the success of the first nine holes, management's confidence continues to increase with respect to resource growth potential at the El Roble mine."

mineralization, and are estimated to be between 71 per cent and 93 per cent
of the drill intercept.
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 sulphide bodies and drilling of new prospective areas below the 2,000-metre level are being conducted from the new main level 1880 adit. Subsequent to the first three holes of the program (ATD-0001 to ATD-0003) where drilling significantly extended mineralization at Zeus as reported in March, 2015 (see Atico news release dated March 10, 2015), the company is reporting the next batch of six drill holes (ATD-0004 to ATD-0009). Infill holes ATD-0004 and ATD-0007 intercepted significantly larger intervals of massive sulphide than had been modelled in the National Instrument 43-101 inferred resource estimate wire frames of Zeus and Aquiles (see Atico technical report dated Aug. 27, 2013). At the levels of mineralization drilled, the interval used in the wire frame calculation of the inferred resource was approximately 49 metres for infill hole ATD-0004 and 54 metres for ATD-0007, whereas the company intersected 70.1 metres and 109.15 metres of mineralization, respectively. Infill hole ATD-0005 intersected 55.85 metres and ATD-0009 intersected 31 metres of mineralization, while, in the wire frame calculation at these levels, approximately 40 metres and 30 metres, respectively, were used. Infill hole ATD-0006 was designed to test the upper central limit of the Zeus mineralization and intersected 7.8 metres, while infill hole ATD-0008 was also in the upper region of the Zeus mineralization but was designed for immediate mine planning purposes and intersected 10.5 metres of mineralization. In the wire frame calculation, approximately 20 metres and 13 metres were used for these levels.
