Oro Gold Resources Ltd.: Cimarron Exploration Progress Report

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 17, 2005) - Oro Gold Resources Ltd. ("Oro Gold") (TSX VENTURE:OGR) has completed additional testing of its 100% owned Cimarron property located less than an hour from the coastal city of Mazatlan in the State of Sinaloa, Mexico. Based on results obtained to date, Oro Gold's technical team believes that real potential exists for a new and significant discovery at Cimarron, and is now gearing towards an increased level of exploration activity on the 80 km2 property.

Of the 129 rock samples collected throughout the property, 47 samples assayed greater than 1 g/t Au, with an average of 3.8 g/t and a high of 128.4 g/t. In addition, follow-up channel sampling from trenches over the Veteranos soil grid anomaly have confirmed the presence of gold and copper in subsurface, with dimensions of over 1 km long and up to 400 m wide. The Veteranos prospect was the first area of the land package to receive focused exploration by Oro Gold, and now represents a viable target for future drill testing. Furthermore, Oro Gold is encouraged by the geological evidence for an IOCG (iron-oxide-copper-gold) type occurrence, previously unrecognized in the region.

Oro Gold's vice-president of exploration, Eric Grill, commented: "We are very excited to hit the ground hard at Cimarron to determine the source of the very high surface gold geochemistry obtained to date and come up with more drill targets."

Veteranos Prospect

The Veteranos target is a quartz and iron-oxide gossanous zone 1.2 km long situated at the core of a silicified ridge and hosted in granodiorite. A total of 1080 meters of hand trenching was completed across the Veteranos soil anomaly where elevated metal concentrations imply the presence of mineralization at depth. Five trenches, each spaced 200 meters apart, were dug to an average depth of 1.5 meters, and channel sampled every 3 meters along the bottom.

Most of the rock exposed in the trenches is deeply oxidized with silicification apparent in several zones. The trench samples across the mineralized structures returned elevated values in the 50 to 500 ppb Au and 100 to 850 ppm Cu range over widths of 10 to 40 meters. There is a strong correlation between the anomalous gold and copper values.

Trench sample values are comparable to those returned by the soil samples. It is interpreted that the trenches were not deep enough to get past the zone of surface leaching; the deep weathering and oxidation does not permit any quantification of value of the mineralization at or near surface. By comparison, samples collected from the Veteranos pit showing, which is creek incised and dozer excavated down to less weathered bedrock, returned substantially higher values across the mineralized structure of 11.4 g/t Au, 24.9 g/t Ag, and 500 ppm Cu over 3 meters. Oro Gold considers the Veteranos prospect to be a high priority drill target.

Other Cimarron Targets

In the central to northern portion of the Cimarron property, three separate targets located within a 20 km2 area have been identified for additional exploration work. All three targets represent limited outcrop showings of mineralized veins and structures and the occurrence of extremely high stream sediment results from numerous drainages with values greater than 200 ppb up to 2,245 ppb Au. The veins observed to date are narrow and northeast trending, containing 5 to 20% specularite, as well as copper-oxide minerals, and return very high gold values. Examples of this type of mineralization include the El Bolante, Los Ebanos, and Dos Monumentos prospects as reported in the table below:



---------------------------------------------------------------------
---------------------------------------------------------------------
# of
Target Areas samples Results
---------------------------------------------------------------------
EL BOLANTE I 7 Average 6.6 g/t Au and 57.5 g/t Ag across
1 meter; includes 12.1 g/t Au and 102 g/t
Ag across 1.6 meters.
---------------------------------------------------------------------
EL BOLANTE II 1 40.5 g/t Au and 211 g/t Ag from a dump
sample.
---------------------------------------------------------------------
LOS EBANOS 16 Average 3.2 g/t Au and 51 g/t Ag across 1
meter; includes a result of 9.8 g/t Au and
81 g/t Ag across 1 meter. A sample of
quartz-specularite ore from the dump
yielded values of 128.4 g/t Au and 314 g/t
Ag.
---------------------------------------------------------------------
DOS MONUMENTOS 1 20.1 g/t Au and 88 g/t Ag from a dump
sample.
---------------------------------------------------------------------
---------------------------------------------------------------------


Also observed in many creeks draining the target areas is the abundant occurrence of magnetite and hematite altered rock float, for which a source has not yet been identified. Float samples have returned values up to 5 g/t Au. This style of mineralization is not typical for the region and may represent what is considered to be porphyry or IOCG-type related.

Exploration Plans

Oro Gold will advance the targets at Cimarron during the dry season over the next four months. Exploration plans include additional prospecting and mapping, as well as geochemical and geophysical surveys to define the targets.

The goal of the program is to develop and prioritize drill targets, and to work towards validating the IOCG target potential. Furthermore, a first phase exploration program will take place on claims recently applied for, totaling more than 150 km2 and located outside of Cimarron in the Rosario-Copala historic gold and silver mining district, which will include prospecting, mapping, and follow-up surveys to define targets.
