TORONTO, May 18, 2011 (Canada NewsWire via COMTEX News Network) — /NOT TO BE DISTRIBUTED OR DISSEMINATED IN THE UNITED STATES/ Cerro Grande Mining Corporation (the “Company”) (TSX-CEG) (formerly South American Gold and Copper Company Limited) Reported an Update on Exploration Activities at its Pimenton porphyry copper/gold Deposits.


Drill hole Nº PP-1 at the Pimenton porphyry copper/gold deposits has been completed at a depth of 430 meters after having experienced several technical delays due to the drill rig being brand new and training of Company personnel. The drill hole has an azimuth of 90 degrees and inclination of 65 degrees and is located at UTM-1984 coordinates – 385667 E – 6406755 N. This drill hole is located 200 meters to the south of Rio Tinto’s drill hole Nº 4, drilled in 2006, which encountered 279 meters grading 0.40% copper and 0.43 grams of gold per ton. Assay results will be reported on drill hole Nº PP-1 on receipt from the assay laboratory.


The Company has just completed an additional Mobile Metal Ion (MMI) study over the known porphyry mineralization at Pimenton and also conducted a Controlled Source Audio-Magnetotelluric survey (CSAMT) with Quantec Geophysical Services. Diamond drill holes totalling approximately 6,000 meters have been sited to test geochemical and coincident CSAMT anomalies related to porphyry mineralization. Drilling will proceed during the coming winter season from underground as well as from secure surface locations.
