Cerro Grande Mining Corporation announced the completion of diamond drill hole CDM 003 at Santa Cecilia, located at UTM 1984 coordinates 6937542N 466750E. Azimuth 180 and inclination minus sixty was drilled to 1,597.7 meters. CEG holds an option on the Santa Cecilia property to acquire not less than a 65.6% from Cerro del Medio ("CDM").
Assaying started at 450 meters below the siliceous cap and extended to 1,597.7 meters.
Preliminary assay results from hole CDM 003 are averaged below over consecutive intervals.
Averaging the assay results between 550 and 1597.7 meters over 1047.7 meters give the following:
0.20 g/t gold, 0.249% copper, 80 ppm molybdenum. The copper equivalent is 0.41% per ton and the gold equivalent 0.60 g/t.
Mineralization consisted of disseminated pyrite, chalcopyrite, with lesser enargite, bornite and molybdenum together with disseminated magnetite within sericitic-silicieous stockworks including argillaceous alteration. From a hole depth of 450 meters the mineralization was within mixed volcanic and sediments passing below 875 meters into diorite and micro diorite intrusive.
The strength and extent of the mineralization cut by CDM 003 is impressive. Exploratory drilling at Santa Cecilia will continue after the end of the Chilean winter season.
Mapping and sampling of the hole was carried out by Watts, Griffiths and McOuat Limited of Toronto, Canada and assaying was done by the ACME lab in Santiago, Chile using fire assay for the gold and ICP for copper and molybdenum. Results of check assays by ALS Laboratories have yet to be received.
To calculate copper and gold equivalents, copper has been taken at US $3.43 per pound, gold at US $1,625.5 per ounce and molybdenum at US $13.11 per pound. These were the market prices for June 15, 2012.
This report was reviewed and approved by Dr. David R.S. Thomson, EVP of Exploration and a Director of CEG and a qualified person under NI 43-101.
Cerro Grande Mining Corporation is a minerals producing, exploration and development company with properties and activities currently focused in Chile.
