Columbus Silver Commences Drilling at Silver Dome

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 20, 2008) - Columbus Silver Corporation (TSX VENTURE:CSC) ("Columbus Silver" or the "Company") is pleased to announce that it has commenced a Phase I drilling program at its 100% controlled Silver Dome Project (the "Property"), located 72 kilometers (km) (45 miles) northwest of Delta, Utah.

The program will consist of up to approximately 3,050 meters (m) (10,000 feet (ft)) of reverse circulation (RC) drilling in up to 20 holes.

Drilling at Silver Dome is designed to test the volume and extent of silver mineralization hosted in Ordovician sandstones. Surface sampling and geological mapping indicate silver occurs in both high-grade structures where values up to 3,080 grams per tonne (g/t) (90 ounces per ton (opt)) silver have been obtained across 1 to 1.2 m (3 to 4 ft) widths, and also as lower grade zones where values between 17.4 and 102.8 g/t (0.5 and 3.0 opt) silver are disseminated for widths up to 22.9 m (75 ft) from the structures, possibly along bedding. Angle drill holes will be placed along known structures at surface, and also down dip under shallow gravel cover north, west, and south of the mineralized surface showings. Geophysics indicates that the shallow gravel cover interpreted to be 15.2 to 30.5 m (50-100 ft) in depth may extend as much as 2.4 km (1.5 miles) into the valley.

Drilling is also planned to test the margins of a circular magnetic anomaly, discovered by a recent ground magnetic survey. The anomaly is interpreted to represent a blind, buried intrusive rock, cutting Paleozoic sedimentary rocks. The strong magnetic anomaly is 2.4 km (1.5 miles) in diameter, and centered approximately 1.6 km (1 mile) southwest of the surface silver showings. Geophysics indicates that the gravel cover in the area of the anomaly is approximately 15.2 to 30.5 m (50-100 ft) in depth. Significant zinc mineralization, along an intrusive margin, has been encountered 3.2 km (2 miles) north of Silver Dome, at the Crypto Deposit currently being drilled by Lithic Resources. Copper and molybdenum deposits are also known to be associated with intrusive rocks in the region.
