Mazorro and Oro Gold Confirm Gold Resource Potential at Cimarron, Mexico

OTTAWA, ONTARIO--(Marketwire - May 6, 2008) - Mazorro Resources ("Mazorro") (TSX VENTURE:MZO) and Oro Gold Resources Ltd. ("Oro Gold") (TSX VENTURE:OGR) are pleased to report the results of a review of the historic drill and channel sample data on the Cimarron property located near Mazatlan in Sinaloa, Mexico. Mazorro has the option to acquire from Oro Gold a 60% undivided interest in the Cimarron property by spending US$2.65 million in exploration expenditures by June 30th, 2011 and by issuing one million common shares in stages by June 30th, 2010.

In the fall of 2007, Mazorro funded a 4,373 sample soil geochemical survey and a magnetic survey covering 326 line kilometers on the Cimarron property. This data is currently being interpreted in preparation for a 5,000 metre reverse circulation ("RC") drill program that is planned to commence in June 2008.

Previous Work on the Cimarron Property

In 1999, Hecla Mining Company ("Hecla") (NYSE:HL) completed 25 RC drill holes testing an area of approximately 350 metres by 250 metres on the Calerita prospect, located in the central part of the 82 km2 Cimarron property. The drilling was completed prior to the implementation of National Instrument 43-101 standard; however, the results are considered to be indicative of a potential gold resource at the Calerita zone. To view the figures relating to the Calerita zone as well as the property-wide surface gold anomalies, please visit Mazorro's website at www.mazorro.com.

Highlights of Hecla's 1999 program include:

- Drill hole 99MHM23 returned 0.6 g/t gold over 106.0 metres (including 1.2 g/t gold over 20.0 metres at surface)

- Channel samples from road cuts returned 0.72 g/t gold over 93.3 metres

- Surface gold anomalies suggest the Calerita zone is open to the north and east, and has km-scale potential

- Target is a high-level gold porphyry and epithermal veins with bulk-tonnage potential

The majority of holes were drilled to a depth of 50 metres. A total of 805 samples were collected at 2-metre intervals. The highest sample result was 3.39 g/t gold and 0.32% copper over 2 metres. A summary of significant drill intercepts is provided in Table 1.

In 2006 and 2007, Oro Gold completed systematic surface sampling, mapping and ground magnetics on the Cimarron property. This work has outlined 7 distinct gold-in-soil anomalies above 30 ppb up to 1,945 ppb gold. The anomalies appear to define a regional structure which can be traced over a distance of 12 km. Over 7,000 soil samples have been collected to date; results from the soil samples indicate individual soil anomalies ranging in size from 3km x 1km to 400m x 400m. Approximately 730 rock chip samples have been collected on the property, 11% of these samples are greater than 1 g/t (81 samples) and 4.5% are greater than 5 g/t (33 samples) with 7 samples greater than 19 g/t Au. Gold mineralization in the Calerita zone appears to be hosted by quartz-epidote veinlets in a dioritic phase of a multi-phase intermediate to felsic intrusion. Based on data interpreted to-date, there appears to be good potential to expand the known mineralized area at Calerita. The drill program is designed to test for possible extensions of the known Calerita gold zone in prospective areas identified by surface sampling.

Michelle Robinson, MASc., P.Eng, a qualified person as designated by National Instrument 43-101, supervised the sampling and quality control program at Cimarron and reviewed the technical content of this news release. Samples were analyzed at Acme Analytical Laboratories in Vancouver, Canada.
