VANCOUVER, BRITISH COLUMBIA, Sep 21, 2012 (MARKETWIRE via COMTEX) — Oroco Resource Corp. /quotes/zigman/501389 CA:OCO -1.85% (frankfurt:OR6) (“Oroco” or “the Company”) is pleased to announce the commencement of an exploration program on its Xochipala Project in Guerrero State, Mexico. The project is located at the southern end of a gold rich district in Mexico called the Guerrero Gold Belt (the “GGB”). To date more than 19 million ounces of NI 43-101 compliant gold resources in all categories have been reported, including Los Filos (goldcorp inc.:13.58 million ounces gold proven)(goldcorp inc.:probable)(goldcorp inc.:measured)(goldcorp inc.:indicated)(goldcorp inc.:and inferred as at 2011); El Limon and Los Guajes (torex gold resources inc.:5.44 million ounces gold measured)(torex gold resources inc.:indicated and inferred ounces as at September)(torex gold resources inc.:2012); and Ana Paula (newstrike capital inc.:currently estimating its resource). The Xochipala Property is the last remaining under-explored target in the GGB that has geological characteristics similar to the known deposits, including the existence of a strong magnetic signature and extensive areas of alteration associated with the contact between intrusives and sediments.

The initial program on the 193 hectare property will include detailed geological mapping, prospecting and rock sampling. A detailed base map will also be prepared which will include historic mine workings, previous drill hole locations and accessibility.

The focus of the mapping and sampling will be the contact area of the sediments and intrusives. Extensive mineralized endoskarn and exoskarn zones are associated with similar contacts throughout the region and host all of the major gold deposits in the Guerrero Gold Belt. Visits to the property by company personnel have noted extensive areas of marbleized limestones (exoskarns) and highly altered, ferruginous intrusives (endoskarns) that are indicative of skarn mineralization in the vicinity of the more than one kilometer of the targeted contact zone.

The sampling program reported previously (August 14, 2012 news release) focused on showings where historical work targeted moderately thin (up to 5.0 meters) mineralized structures and contact zones. The current program will be considerably more extensive and will channel sample all showings, rock exposures along road cuts and other areas of altered outcrop with the intention of developing a larger target that will include both high grade structural and contact mineralization and lower grade skarn mineralization.

On receipt of assays from this program a diamond drill program will be initiated to test the anomalous areas noted from the mapping and sampling. It is anticipated that drilling will start in the fourth quarter of 2012.
