SDRG(1.75)Silver Dragon Begins Underground Development and Test Mining of the La Chiva Zone At Its Cerro Las Minitas Silver Project in Durango, Mexico

DURANGO, Mexico, May 23, 2007 (PRIME NEWSWIRE) -- Silver Dragon Resources Inc. (OTCBB:SDRG) is pleased to announce the beginning of underground development and test-mining of the La Chiva zone at its Cerro Las Minitas Silver Project in Durango, Mexico. The La Chiva zone is a shallow mineralized body which was discovered during drill-testing in 2006. It is estimated that the La Chiva zone contains more than 54,000 tons of oxide mineralization with grades of approximately 350 g/ton silver, 4.76% lead, and 2.59% zinc. These grades have been estimated conservatively from surface drill intercepts. Drill data also indicates the existence of a supergene enrichment zone a short distance below the present level of the Guadalupe Ramp. Upon receipt of sample development material from this zone, grade estimates are expected to increase.
Under the supervision of Silver Dragon's management, a contractor from Mexico is managing the testing and development of the enrichment zone. As of the date of this release, high grade silver, lead, and zinc deposits from the Guadalupe Ramp have been accessed and underground development has commenced. Where initially accessed, the La Chiva mineralized zone was found to be 1.7 meters wide and appeared to be of high grade. Assay results are pending. Development material is being trucked to the surface, where it is stockpiled for metallurgical testing. Material not used for metallurgical testing will be sent to toll mills in the region for the recovery of contained metals.
Two additional mineralized oxide bodies, similar to the La Chiva zone, are now known in the Puro Corazon area. The Guadalupe Ramp will also enable mining and haulage access to those bodies as the Company progresses.
Mining of the La Chiva body will allow the Company to fine-tune its mining methods, make reliable estimates of mining costs, provide bulk samples for ongoing metallurgical test work, and continue exploration for additional high-grade resources.
Preliminary flotation and leach testing of oxide material from Cerro Las Minitas has been completed. The Company has decided to begin development of the La Chiva zone to acquire representative material for more advanced metallurgical testing and to begin toll milling of excess development material to recover metals.
Drilling is now in progress to explore additional mineral targets defined in 2006 and 2007. Several significant new intercepts of mineralization have been made, but assay results are still pending. These values will be reported upon receipt.
