Oro Gold's Geochemical Survey Defines Large Scale Gold and Copper Anomaly on Cimarron Property, Sinaloa, Mexico

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Feb. 2, 2006) - Oro Gold Resources Ltd. ("Oro Gold") (TSX VENTURE:OGR) has produced positive surface results for the second phase of exploration on the Company's 100% owned Cimarron property, located in the Rosario gold and silver mining district in the State of Sinaloa, Mexico.

The results come from a recently completed extensive geochemical survey covering over 30% of the 7,850 hectare (79 km2) Cimarron property, and consist of 1,428 soil samples collected over a 43 line-kilometre grid. The new data has defined large scale gold and copper soil anomalies at five zones within the property, specifically the Huanacaxtle, Calerita, El Prado, Betty and El Bolante target areas.

Management considers the results very significant with over 10% of all Cimarron soil samples containing anomalous concentrations of gold and copper, as reported in Table 1 below. Oro Gold's VP Exploration, Eric Grill, commented: "We are encouraged by the results of the geochemical survey as they appear to define the source of the very high stream sediment gold anomalies. We have now completed another important step towards defining future drill targets."

Based on the ongoing positive results Oro Gold will continue to define and prioritize the surface targets with: (i) additional soil geochemistry, (ii) trenching and (iii) an airborne magnetic and radiometric survey. The objective of the next phases of exploration will be to prioritize targets for future drilling.

The Huanacaxtle and Calerita target area represents a broad geochemical anomaly for gold and copper that overlaps a 2.5 km2 area located in the central portion of the Cimarron property. Within the broad anomaly, 48 soil samples returned values more than 100 ppb Au. These higher grade samples define three priority areas: (i) Calerita with values as high as 475 ppb Au and 664 ppm Cu, (ii) south Huanacaxtle with values as high as 1387 ppb Au and 230 ppm Cu, and (iii) north Huanacaxtle with values as high as 247 ppb Au and 177 ppm Cu. The anomalous gold-copper geochemistry in Calerita and south Huanacaxtle appears to be related to: (i) quartz-tourmaline breccias and (ii) zones of semi-massive specularite and quartz hosted in granodiorite. At north Huanacaxtle, the gold-copper geochemistry is related to quartz-epidote-specularite replacement zones in felsic tuffs.

The El Prado target area is a northwest trending anomaly 200 metres long by 80 metres wide. Within the zone, gold values in soil range from 66 to 1010 ppb Au. Field verification of this anomaly shows that it is underlain by a quartz-specularite stockwork zone hosted in variably silicified felsic tuffs. This stockwork zone is partially exposed in a stream valley over a minimum true width of 32 metres.

The Betty target area returned eleven soil sample values of more than 100 ppb Au, with a maximum of 1183 ppb Au. A fault-exposed scarp shows that at least part of the Betty anomaly is underlain by a strongly silicified tuff with up to 20% fracture-controlled specularite and quartz.

The El Bolante target area returned gold values of 18 to 108 ppb Au as well as a strong base metal signature with copper values as high as 203 ppm. The El Bolante anomaly is interpreted to host a diorite intrusive with 3 to 5% disseminated magnetite.
