Mazorro and Oro Gold Commence 5,000m Drill Program at Cimarron, Mexico

OTTAWA, ONTARIO--(Marketwire - June 10, 2008) - Mazorro Resources Inc. ("Mazorro") (TSX VENTURE:MZO)(FRANKFURT:JAM) and Oro Gold Resources Ltd. ("Oro Gold") (TSX VENTURE:OGR) are pleased to announce that the first phase of a 5,000 metre reverse circulation ("RC") drill campaign has commenced at the Cimarron property, located 40 km east of Mazatlan in Sinaloa, Mexico. This program will consist of 2,500 metres of drilling which will be followed by a second phase mid-summer once assay results from the first phase have been evaluated. The drill program is designed to target the kilometre-scale gold anomaly at the Calerita prospect, as well as drill-test anomalies identified from the recently completed soil geochemical and magnetic surveys covering 326 line-kilometres.

The initial portion of the drill campaign will focus on confirming and expanding the 350m by 250m Calerita target which was drill delineated in 1999 by Hecla Mining ("Hecla") (NYSE: HL) (reported in May 6 press release). Highlights from the 1999 drill campaign at the Calerita target include: drill results of 0.59 g/t gold over 106 metres (non 43-101 compliant) and surface trench values of 0.72 g/t gold over 93.3 metres.

Calerita Target

Results from the soil geochemical survey completed last fall have further expanded the Calerita gold-in-soil anomaly by over 600 metres to the northeast and include samples grading up to 1.39 g/t Au in soil. A ground magnetic survey has been completed over the entire project area. An initial review of these results indicates that the gold anomaly may be related to an intrusive body at depth. Detailed interpretation and magnetic inversions are currently being completed in order to further refine targets throughout the property. Mazorro and Oro Gold believe that there is potential to expand the known mineralized area at Calerita. Eight holes are planned in the Calerita area to confirm and expand the targets at depth, as well as to test the extension of the new gold anomalies identified from the soil sampling program. The average depth of the previous drill program in this area was 50 metres whereas this program is planned to drill-test to a depth of 200 metres.

The gold mineralization in the Calerita zone appears to be hosted by quartz-epidote veinlets in a multi-phase intermediate to felsic intrusion.

New Targets

As part of the first phase of the drill program, an additional 4 holes are planned to test other gold-in-soil anomalies throughout the 8,192 hectare Cimarron property. Over 7,000 soil samples have been collected to date. This work has outlined 7 distinct gold-in-soil anomalies above 30 ppb up to 1,945 ppb gold. Results from the soil samples indicate individual surface anomalies having dimensions ranging from 400m by 400m to 3km by 1km.
