VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 13, 2010) - Prospero Silver Corp. (TSX VENTURE:PSL) is pleased to announce that its Mexican subsidiary, Minera Fumarola, SA de CV, has acquired by staking the Bermudez project. The project area is in western Chihuahua State, close to the Sonora border, and comprises a 800 hectare claim, covering the full extent of a system of NW-SE striking veins approximately 2 kilometers in length. The veins, which exhibit widths up to several meters wide, consist of multistage banded crystalline and amorphous silica phases and platy calcite replaced by silica.

The Bermudez project is located near existing operations namely the Mulatos Mine in Sonora and the Dolores Mine in Chihuahua to the northeast, and the Pinos Altos Mine in Chihuahua to the east. The Bermudez vein system is hosted along the margins of a rhyolitic dike complex which is emplaced in andesitic flows and tuffs of the lower part of the Upper Volcanic Series. The veins pinch and swell along strike and exhibit wallrock silicification with stockwork veining up to 40 meters in width.

Preliminary geochemical sampling (16 samples) indicates 9 anomalous silver assays (2.0 to 20.3 ppm), 3 anomalous gold assays (.143 to .475 ppm), and elevated barium assays (up to 2660 ppm). Silica and fluid inclusion petrography exhibit low temperature silica phases including crystalline quartz with abundant vapor-rich inclusions and suggests the system exposes the upper portions of epithermal mineralization which could be located at relatively shallow depth.

This acquisition by staking reflects Prospero's Mexican exploration team's knowledge of the Mexican exploration landscape and ability to acquire free ground as it becomes available. Follow-up detailed geology and geochemistry will be undertaken to define the structurally and geochemically higher priority drilling targets at the Bermudez property.
