Atico Mining (TSXV:ATY) put out impressive drill results from its El Roble mine in Colombia on Wednesday, reporting grades of 6.26 percent copper and 1.85 g/t gold over 70 meters in one hole. An intercept of over 6 percent copper is nothing to shake a stick at, and there was definitely a reaction from the market in response. Atico's share price jumped as much as 15 percent on the news during Wednesday trading hours before finishing at $0.48, or 5.5 percent up from Tuesday's close. Roughly 150,000 shares of Atico traded hands, over twice the company's average volume. The company is conducting an ongoing infill drill program at El Roble to better define and expand mineralization at the mine. So far, drilling has successfully continued to extend mineralization of the Zeus massive sulfide body at the project. Overall, the company reported results from six drill holes at the project, with other highlights including: 7.5 percent copper and 1.31 g/t gold over 39.35 meters 6.07 percent copper and 5.65 g/t gold over 29.6 meters 6.9 percent copper and 3.93 g/t gold over 31 meters "Infill drilling at El Roble continues to intercept high grade mineralization at the Zeus massive sulfide body beyond the previously outlined mineralized shell, adding further confidence to our view that mineralization remains strong and open at depth," said Atico CEO Fernando E. Ganoza in Wednesday's release. El Roble has seen other positive results from drilling at the Zeus body this year as well. Highlights from a March release on the drill program include intercepts of 86.4 meters of 5.04 percent copper and 3.71 g/t gold, as well as 116 meters of 3.05 percent copper and 2.38 g/t gold.
