Dia Bras Exploration Discovers High Grades of Silver Deposit at its Promontorio Mine

Dia Bras Exploration, a Canadian exploration and mining company, has announced that prolonged drilling at its Promontorio mine has revealed broad disseminated silver mineralization zones.

The firm has also given an up-to-date information on its pilot mining activities at the Cusi property for December 2011 and January 2012.

Dia Bras Exploration has concluded five new drill holes in the Promontorio mine’s disseminated zone and further intends to drill an additional 13 holes, which will be drilled from beneath the ground. The five drill holes lie in a silicified rhyodacite zone that includes narrow argentite veinlets and disseminated argentite with small quartz veinlets and poor sulphide. This zone denotes a potential for underground bulk mining.

Dia Bras Exploration’s President and CEO, Daniel Tellechea stated that the company continues to identify wide silver mineralization zones, and this has been specified by 151 drill hole that intersected 109 m of 157 g/t silver. Tellechea added that these results along with the prior results validate the expansions of a high-grade disseminated silver deposit, and this may justify a considerable increase in silver production as the company continues to develop and expand its mining operations at the Cusi property.

Dia Bras believes that the lower grade parts of drilling results are potentially mineable as part of a massive mining campaign. Moreover, the exact thicknesses remain unknown because Dia Bras needs additional holes in this disseminated silver mineralization zone before determining them. On the other hand, the firm’s geologists have concluded that these core thicknesses are probably near to exact thicknesses.
