ORO GOLD DRILLS 3.6 G/T GOLD OVER 81.8 METRES IN NEW ZONE AT TRINIDAD PROJECT, MEXICO

Oro Gold Resources Ltd. is providing gold assay results received for two more diamond drill holes in the high-grade gold zone at the Taunus target and one drill hole in the Colinas target on its 100-per-cent-owned Trinidad property near Mazatlan, Mexico.

Hole 09TR025 returned 3.6 g/t gold over 81.8 metres, including 7.1 g/t gold over 31.9 metres, in the high-grade new zone at Taunus. This hole drilled in-between the intersections in 09TR015 (5.3 g/t gold over 65.9m) and 09TR019 (6.3 g/t gold over 30m) and confirms that the high-grade gold mineralization in this area is predominantly flat lying for over a distance of 90 metres and remains open in multiple directions. The zone is interpreted to extend to the west and south, and may be offset to the north by a post-mineral fault. The true width of the new zone appears to be about 60 metres in this area (refer to this link to view the section)

Hole 09TR023 returned 1.5 g/t gold over 17.8 metres, including 3.8 g/t gold over 5.8 metres. Hole 09TR023 is located approximately 250 metres south of the flat lying zone described above and is interpreted to be a potential near vertical feeder structure. This intersection is located 70 metres vertically below the intercept of 4.1 g/t gold over 12.9 metres in 09TR020. Several other intercepts shown in the table below indicate the gold mineralization is open to the west. The hole was not completed to target depth due to drilling problems short of cutting the projected down-dip extension of the lower mineralized zone in 09TR020 that returned 5.3 g/t gold over 13.4 metres.

09TR024 returned 1.3 g/t gold over 4.5 metres testing the Colinas target area located more than 700 metres south of drill holes 09TR020 and 23.

Continuous composite intervals greater than 2m length and
greater than 0.2 g/t gold (and can include up to 2m less
than 0.2 g/t gold). Composites of less than 5m at 0.5 g/t
gold are not reported. Intervals posted are down-hole drill
lengths.

Frank Powell, Oro Gold's Vice President, stated, "The results of drill hole 09TR025 have exceeded our expectations, being one of the longer significant mineralized intervals intersected to date. This hole was important to confirm the continuity and shape of the gold distribution in the new zone. We now have good evidence that it is nearly flat lying. We will continue to focus on expanding it further to the west, while also targeting other potential extensions to the north, the south, and down-dip."

Results for 25 diamond drill holes, totaling 4,634 metres, have been received to date. Twelve of these holes have drilled into the new discovery zone. The other 13 holes were aimed at confirming previously recognized gold mineralization in reverse circulation drilling, located within 1 kilometre of the discovery area. The drilling continues with two diamond drill rigs to expand the high-grade gold zones and to test new targets identified at Taunus, Bocas and Colinas. Holes 09TR026 and 027 are currently drilling untested areas at depth located south of the new zone in-between holes 09TR020 and 09TR012/15/16.

The 2009 exploration program comprises three project initiatives: (1) two diamond drill rigs are currently drilling Taunus targets to expand and define the high-grade mineralization with the objective of increasing the gold resource. Modern exploration tools are being utilized to identify and prioritize drill targets including geophysics, clay studies, and structural mapping; (2) a third diamond drill rig will be mobilized to drill the El Habal target and proceed to test other developing targets outside of Taunus with the objective in discovering and defining a new gold resource area. The El Habal target is located 15 kilometres west-northwest of Taunus, and was previously drilled returning 1.3 g/t gold over 261 metres (not NI-43-101 compliant); and (3) a regional exploration program has commenced with the objective of making a new gold discovery along the 80-kilometre trend in which the Taunus deposit lies.

Additional information, including plan maps, sections, diamond drill hole data, and links to an exploration update provided on a regular basis from Trinidad site and a 3-d model pertaining to the diamond drill program can be viewed on Oro Gold's website.

The Taunus gold target is interpreted as an oxidized, low-to-intermediate sulphidation, epithermal vein system. The mineralization is characterized by multiphase stockwork veining and hydrothermal brecciation hosted in a clastic unit, quartz-feldspar porphyry intrusive and andesite volcanics. Oro Gold has identified 10 other gold targets within the 650-square- kilometre Trinidad district that require follow-up exploration. Based on what the Company is accomplishing at the Taunus gold target with diamond drilling, this will aid in further defining and prioritizing these additional targets toward drilling. Oro Gold's technical team is interpreting this district to be situated in a northwest-trending structural corridor that extends for at least 80 kilometres. It is formed by active, deep-seated, major fault structures. There is evidence of this in the recent drilling, based on intersecting a thick clastic and conglomerate sequence that has a vertical profile exceeding more than 250 metres in depth. The Taunus deposit is interpreted to be hosted in a local pull-apart basin within this trend.

Quality Assurance - Quality Control

The Trinidad project exploration is under the direction of Dr. Dominique Fournier, Vice President Exploration, a qualified person as designated by National Instrument 43-101 who has reviewed the technical content of this release. Thorough quality assurance and quality control program (QA/QC) protocol was utilized on the project including duplicate, blank and standard samples with each batch of assays. The core samples were submitted directly to Inspectorate de Mexico, S.A de C.V. for preparation in Durango, Mexico, and analysis in Reno, Nevada. Analysis was conducted on 1 assay ton samples with over 20% as QA/QC samples. Analysis of gold was by fire assay, with a gravimetric finish on samples exceeding 5 g/t gold. The gravimetric assay results were used for the reported composite intervals.
