Oro Gold Drills 10.82 g/t Gold Over 5.74 Metres at San Isidro

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Feb. 19, 2007) - Oro Gold Resources Ltd. ("Oro Gold") (TSX VENTURE:OGR) has received encouraging assay results for the first-phase diamond drill program recently completed on the San Isidro property, located in Sinaloa, Mexico. The results confirm San Isidro as being a new high-grade vein discovery in an area that has received no prior exploration. A second round of drilling at San Isidro has now commenced.

"These are early days for exploration in this unrecognized area and we have already drilled into a gold-bearing vein structure," stated Eric Grill, VP Exploration. "Our job now is to determine the full size potential of the system, through additional surface exploration and drilling."

Metallic and fire assay analyses have verified an overall significant increase in gold and silver content compared to initial results by ICP method, and confirmed the presence of coarse gold at San Isidro. Highlights of the new results are as follows:

(i) Results by metallic method on samples of approximately 500 g in weight.
All other results by fire assay method utilizing one assay ton.
(ii) Average of 2 sample analyses prepared from opposite core halves that
returned 32.32 g/t and 84.10 g/t Au respectively.

True widths have not been determined for the reported drill intercepts,
however they are believed to approximate the actual stockwork vein and
structural zone thicknesses.


The drilling tested the down-dip projection of gold-bearing quartz veins observed at surface, which resulted in the identification of low sulphidation stockwork vein zones up to 15 metres wide in six of the seven holes drilled. It is interpreted that the stockwork zones occur in the hanging wall of a major northwest-trending structural corridor that has been mapped on surface over a distance of 500 metres. The drill results to date suggest the potential for precious metal mineralization associated with stockwork vein zones peripheral to high grade structures. The best results to date have come from the hole containing visible gold, hole 06SI-05, which is located in closest proximity to this inferred structural corridor. A geological description of the mineralized intervals in the holes that reported favorable results is summarized below.

06SI-01: The narrow high-grade vein target structures which returned up to 72 g/t Au at surface were intersected at depth. The best interval was from 14.8 to 16.5 metres (1.7 m) which returned 2.38 g/t Au, and is characterized by moderate to strong brecciation, silicification, and stockwork quartz veinlets with minor sulphide. Quartz and sulphide stringers occur in wallrock, suggesting a low-grade wallrock halo to the fault breccia-vein zones. The mineralized zone is open to the north and west.

06SI-05: This hole intersected silicified dacite volcanics with moderate to strong stockwork quartz vein zones up to 15 metres in width between 0 and 35.9 metres depth. Coarse visible gold was observed near surface in one veinlet zone at 3.5 metres depth which returned a metallic analysis of 84.10 g/t Au and 103.0 g/t silver over 1 metre, with lower grade assays in the 0.1 to 2.5 g/t Au range occuring in the adjacent stockwork zone. The visible gold interval does not correlate with any samples that were taken at surface. Additional zones of quartz stockwork veining and breccias were encountered down hole including a 6 metre wide interval that returned gold values in the 0.2 to 0.6 g/t range, and two narrow 1.0 metre and 1.6 metre wide intervals in the 2.0 to 3.0 g/t range. The mineralized zone is open to the south and west.

06SI-07: This hole tested the down-dip extension of the stockwork zones in 06SI-01, and also intersected stockwork quartz vein zones up to five metres wide between 24 and 46 metres depth, including a 0.5 metre interval which returned 4.01 g/t Au. Below this, narrow quartz vein zones returned 0.1 to 1 g/t Au down to the bottom of the hole.

Oro Gold is currently drilling an additional 500 metres in 4 diamond drill holes to test the extensions of the known mineralization. These holes are 100 metre step-outs located along strike to the north and south, and across strike to the west. The Company is also planning additional fieldwork designed to identify possible new target areas, including a ground geophysical survey covering the projected trend of the mineralized structural corridor both north and south of the main zone in areas of post-mineral volcanic cover and overburden.

More information regarding the drill program is available on the Company's website www.orogoldresources.com, including drill hole location maps and photographs of core.

Oro Gold maintains an extensive quality control program in the preparation, shipping and checking of all samples from the property. As part of this program, for every 30 samples submitted for analysis, one blank, one certified standard of known gold content, one coarse reject duplicate and one pulp duplicate analysis is performed. One sample pulp from each 30 samples is also sent for outside analysis. Standards, blanks and duplicates make up approximately 15 per cent of the samples assayed. Half-core samples have been retained on-site for verification and reference purposes. Core samples consisting of half-sawn HQ drill core were shipped to SSP in Hermosillo, Sonora, for sample preparation. Sample pulps were then forwarded to Acme Analytical Laboratories Ltd. in Vancouver, B.C., for geochemical analysis. The exploration drill program and sampling protocol has been reviewed and verified by Michelle Robinson, P.Eng, who is the qualified person as defined by National Instrument 43-101 and has reviewed the content of this press release.
