Oro Silver Intersects 6.1 g/t Gold and 49 g/t Silver Over 2.3 Metres; Confirms Potential of El Orito Vein at El Compas Mine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 12, 2008) - Oro Silver Resources Ltd. ("Oro Silver") (TSX VENTURE:OSR) has received encouraging drill results at its wholly owned El Orito concession, located over 300 metres east of the El Compas mine. These results confirm a new vein discovery in an unexplored area and expand the potential for additional resource development at Oro Silver's El Compas property, Zacatecas, Mexico.

The El Orito vein is approximately 400 metres east and sub-parallel to the El Compas vein system. The most recent gold and silver production in the area is from the El Compas Adit zone, which is the focus of Oro Silver's latest drilling program. The El Orito vein has been mapped on surface over a distance of 900 metres, and has been exploited by shallow surface workings.

Drill hole 08COM007, the first of two core holes completed at the El Orito target, intersected a quartz vein approximately 75 metres below surface that returned 6.09 g/t gold and 49.0 g/t silver over a width of 2.3 metres from 91.9 to 94.2 metres down the hole. The vein exhibits bladed and banded textures characteristic of epithermal vein systems and similar to the veins observed at the El Compas mine.

Assays are pending for a second hole (08COM009) that intersected a wider and similarly textured quartz vein zone approximately 40 metres directly below the intercept in 08COM007. Additional drilling is planned in this area to test the extent of the gold-bearing vein zone to the north and south, and at depth.

Oro Silver maintains a strict quality control program. All samples were submitted directly to Inspectorate de Mexico, S.A de C.V., for preparation in Mexico, and analysis in Reno, Nevada. Analysis was conducted on 2 assay ton samples, with standards and blanks inserted every 30 samples. Analysis of Au was by fire assay, with a gravimetric finish on samples exceeding 3 g/t Au. Analysis of Ag was by atomic absorption, with a gravimetric finish on samples exceeding 200 g/t Ag. Triple acid digestion was used on all samples. Herve Thiboutot, P. Eng., Vice-President of Exploration and Development, a qualified person as defined by National Instrument 43-101, supervised the exploration program and has reviewed the technical information in this press release.
