Drilling Commences At Browns Canyon Gold Project
VANCOUVER - Columbus Gold Corp. has commenced drilling at its Browns Canyon gold project, located approximately 20 kilometres (12 miles) west of Barrick Gold's Archimedes open pit gold mine, in the highly prospective Battle Mountain gold trend of Nevada, which is known to contain over 100 million ounces of gold with about 24 gold mines throughout the trend.
The program will consist of up to 16 RC holes in up to 2,730 m (9,000 ft) of drilling. Preliminary sampling at Browns Canyon yielded gold values up to 3 g/t along a zone of silicification, sparsely exposed through cover, with a strike length of 2,000 meters (6,600 ft). The mineralization is Carlin-style, hosted in Devonian and Mississippian limestones, shales and siltstones. Follow-up geologic mapping and geochemical grid sampling was performed in 2011 with four hundred samples along the silicified zone defining a coherent gold anomaly (from 10 ppb to 3 g/t gold) about 2,000 meters long and reaching up to 390 meters at its widest point (6,600 by 1,300 ft). This anomaly becomes covered on the north end for about 600 meters (2,000 ft) and then reappears, albeit more weakly and less coherent, on the strike for another 900 meters (2,970 ft). The overall anomaly could be as much as 3,500 meters (11,550 ft) long on strike if it continues in bedrock below the covered area.
