Atico reports union negotiations at El Roble Mine, Colombia; drilling stopped, exploration continues

  Vancouver, April 15, 2013 - Atico Mining Corporation (TSX.V: ATY | OTC: ATCMF) reports that Minera El Roble (MINER), current operator of the mine, is engaged in its annual negotiations with the worker's union. As part of this on-going process, the worker's union has called for a strike. Atico has temporarily halted drilling within the premises of the mine. The company's employees are not engaged in this labor disruption and continue to prioritize and prepare drill targets while conducting fieldwork in other areas of the 6,679 hectare property.

Atico plans to resume underground and surface drilling immediately following the resumption of mining operations at El Roble mine. Negotiations between MINER and the union, which represents approximately 60% of the mine's workforce, are ongoing as both parties work to bring a swift and satisfactory resolution to the strike.

Fernando E. Ganoza, CEO of Atico Mining, commented, "We are optimistic that current negotiations will lead to a satisfactory settlement for both Minera El Roble and its unionized workers. In the past, these negotiations have lasted between two and six weeks."

Fernando E. Ganoza continued, "Our exploration teams are ready to resume drilling as soon as the negotiation process comes to an end. The district exploration program continues with geochemistry and geology in three newly identified drill targets within El Roble property."

The 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. Exploration 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.
