VANCOUVER, BRITISH COLUMBIA–(Marketwire – Feb. 21, 2012) – Defiance Silver Corp (TSX VENTURE:DEF) (“Defiance”) is pleased to announce the acquisition by staking of the 24,500 hectare blanket claim covering the historic Minerva Mining District in northern Coahuila State, Mexico. The Minerva Mining District is located 5 km west of the La Encantada Silver mine owned by First Majestic Silver Corp. which is projected to produce over 4 million oz of silver in 2012.

The Minerva claim completely surrounds a number of older claims whose historic workings formed the Minerva Mining District which in turn is part of a northeast – southwest trend of four mining districts. The Minerva Mining District consists of carbonate hosted replacement mineralization similar to that at La Encantada as well as numerous occurrences of disseminated mineralization in a granitic stock. Chip sampling from outcrops and grab samples from dumps associated with historic workings on inlier claims returned carbonate hosted manto style mineralization grading 0.15 – 0.45 g/t gold, 270 – 565 g/t silver, 11.1 – 13.6% lead, 0.8 – 16.7% zinc and 0.31 – 0.41% copper. Disseminated style mineralization associated with an intrusive stock returned values of 53 g/t silver, 2.2% lead, 0.11% copper and 7.9% zinc.

The claim has good access from Muzquiz by 165 km of paved and gravel roads with several smaller towns close to the claim providing good infrastructure.

Defiance intends to carry out a preliminary exploration program of satellite imagery analysis, surface sampling and mapping, and geophysics to define drill targets below the shallow pediment cover.

Defiance Silver Corp is a near-term silver producer in Mexico. With a strong team of proven mine finders and developers, Defiance is focused upon being an aggressive explorer and acquirer of exploration and development silver projects in the historic billion-ounce silver producing Zacatecas District.
