Cerro Grande Mining Corporation Announces Preliminary Drill Hole Results at its Santa Cecilia Prospect

TORONTO, March 22, 2012 /CNW/ - Cerro Grande Mining Corporation (the "Company" or "CEG") (TSX-CEG; OTCQX-CEGMF) announced today preliminary results from its first diamond drill hole at the Santa Cecilia prospect on which it holds a 65.6% option. Santa Cecilia is located directly adjacent to Exeter Resources Caspiche prospect, 16 km south of Kinross's Maricunga Mine (ex Refugio) and 12 km north of the Barrick/Kinross's Cerro Casale project, all located at the southern end of the Maricunga District of Chile.

Diamond drill hole CDM 002 at Santa Cecilia was drilled to a depth of 1,738.8m. The WGS 84 UTM coordinates for the drill hole are 466500E, 693795N. The bearing of the hole is 180 degrees with an inclination of -60 degrees.

A Summary of the preliminary assay results are given below:

From 870m to 960m (90m)	0.06g/t Au	0.13% Cu	0.006% Mo
From 960m to 1432m (432m)	0.12g/t Au	0.24% Cu	0.013% Mo
From 1432m to 1592m (160m)	0.05g/t Au	0.20% Cu	0.022% Mo
From 1592 to 1738.8	Assay results pending

Drill hole CDM 002 was drilled to test matching gold and copper Mobile Metal Ion anomalies within a strong CSAMT geophysical anomaly. The drill hole from a depth of 870 meters to 1,738.8 meters, over a length of 868.8 meters (of which we have assay results from 870 meters to 1,592 meters or 722 meters), showed remarkably persistent and strong copper, gold and molybdenum mineralization which confirm the value of the geochemical and geophysical anomalies.

A second hole CDM 003, is presently drilling at WGS 84 UTM coordinates 466750E 6937545N bearing 170 degrees with an inclination of -60 degrees. CDM 003 is being drilled parallel and 250 meters to the east of and 380 meters to the south of CDM 002 and is expected to enter mineralization at a lesser depth than CDM 002. Results from this hole, in light of the existing geochemical, geophysical and now assay values from CDM002, should establish the continuity of the mineralization and may indicate higher values.

Assaying is being done by ACME Analytical Laboratories Ltd. (Chile). Check assays have been sent to ALS Minerals Laboratories in Chile and the results are pending. Assays by both laboratories are being conducted by fire assay and ICP-32.
