Piranhas Regional Geological Map over Landsat Image

In July 2008, September 2009 and December 2009 Brazauro entered into three Option Agreements to acquire 100% of the Piranhas property situated approximately 20 kilometers southwest of the Company’s Tocantinzinho project. These agreements include four claims and one exploration license for a total of 34,533 hectares.

Piranhas is a well-known and historic garimpo that has been active for the last 40 years. The unofficial artisanal gold production from near surface has been reported as more than 836,000 ounces of gold, all produced by primitive methods.

Geologically, the Piranhas property is one of the most interesting in the Tapajós, where a sequence of geotectonic events can be responsible for diverse styles of gold mineralization. The local basement is the gold-fertile Parauri granite, the same unit which hosts the Tocantinzinho gold deposit. Overlying the Parauari granite, there is a cover of volcanic rocks of the Salustiano formation and intruding all that sequence, there is a stock of the Maloquinha granite. Gold mineralization may be found in all these rock types.
