Atico intercepts 87 meters with 3.52 % Cu and 2.7 g/t Au at El Roble mine, Colombia

 
  Vancouver, July 03, 2013 Atico Mining Corporation (TSX.V: ATY | OTC: ATCMF) is pleased to report results of eight underground drill holes at El Roble mine in Colombia which confirm the extension of mineralized boundaries along strike and down-dip of Maximus and Goliath bodies. The latest mineralized intercepts in these massive sulphide bodies support previously interpreted boundaries and high copper and gold grades.

Fernando E. Ganoza, CEO, commented, "The team on the field has done a superb job at discovering significant new resources below the 2000 meter elevation, the lowest production level at El Roble mine. We are very excited to have been able to extend the boundaries at depth of the Maximus body, confirm the boundaries of Goliath and consistently intercept high grade Cu-Au mineralization while doing so. The latest reported drill results support the recently published resource estimate on the El Roble mine and our initial view on the size of the Maximus and Goliath massive sulphide bodies, which will become primary targets for mining activities below the 2000 meter elevation." Mr. Ganoza continued, "Drilling has successfully identified massive sulphide bodies at depth, to the north and center of the known strike length of El Roble mine. The underground drill program will now focus on the south end of the deposit where we believe geological potential exists to discover additional massive sulphide mineralization."

Underground diamond drilling program

Drill holes ATDHR-30 and ATDHR-33 through ATDHR-36 tested the boundaries of the Goliath body along strike and to the hanging-wall and footwall confirming previously interpreted boundaries. Mineralization in Goliath has now been extended to the north and is now interpreted as an ellipsoidal body.

Drill holes ATDHR-37 through ATDHR-39 intersected mineralization in the Maximus body along strike and at depth. ATDHR-38 and ATDHR-39 extended mineralization 12 meters above the previous intercept. ATDHR-40 has been completed and intercepted massive sulphide 10 meters below the known mineralization limit extending the body down-dip extent. Assay results for ATDHR-40 are pending.

Drilling will concentrate on the south-end of the deposit to test for massive sulphide below the 2000 meter elevation where alteration and trace element vectors suggest that the mineralization remains open at depth and along strike to the south.

New 1886 meter elevation adit at El Roble Mine

Maximus and Goliath's location at the center of the strike length of known mineralization and closest to the 2000 meter elevation make them primary targets for initiating mining activities below the current mine workings. The company has validated the location and upgraded the design of a new adit at the 1886 meter elevation, 114 meters below current mine workings, which will provide access to Maximus and Goliath bodies for mining activities. The new adit will also provide a platform from which diamond drilling can intercept the newly discovered massive sulphide bodies perpendicular to their strike direction, which the company believes necessary to be able to estimate measured and indicated resources.

El Roble Property

The El Roble property is the site of an operating underground copper and gold mine with nominal capacity of 400 tonnes per day. Over the past 22 years the mine has processed 1.5 million tonnes of ore at an average grade of 2.5% copper and an estimated 2.5 g/t gold. Copper and gold mineralization at El Roble occurs as volcanogenic massive sulfide (VMS) lenses. Atico's underground drilling has discovered additional high-grade mineralization below the mine workings. Exploration on the surrounding 6,679 ha property over the past two years has defined a productive contact and an enclosing package of host rocks that extend 10 kilometers across the property. The entire strike length is marked by VMS mineralization occurrence indicators.

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.
