Preliminary results from deep hole FCTU0033 at Chega Tudo suggest the extension of the mineralization to a vertical depth of approximately 400 meters and is open at depth. Previous resource drilling campaigns at the Project had delineated the mineralization down to 170 meters vertical depth at Cipoeiro and 130 meters vertical depth at Chega Tudo. The overall results confirm the potential to increase gold mineral resources at the Project's Cipoeiro and Chega Tudo ore bodies, currently estimated at 69,887,500 tonnes at 1.12 grams per tonne totaling 2.5 million ounces. A full re-evaluation of the resource at the Cipoeiro and Chega Tudo ore bodies is expected to be completed in April 2012.

"These most recent drill results continue to underscore the value of the Gurupi asset," said Gary German, Jaguar's Chairman. "The quality and continuity of the mineralization at the Cipoeiro and Chega Tudo ore bodies have been in line with or have exceeded our expectations for continued resource expansion."

While the Company has focused recent drilling and exploration on the Chega Tudo and Cipoeiro ore bodies, the 100 percent Jaguar owned extensive Gurupi concession includes 12 additional, identified targets within the region (see map below). These additional targets have not been included in any of the Company's resource estimates or feasibility studies related to the Gurupi project. They have been identified by favorable geology, structures, old artisan mine works, soil and channel sampling anomalies and exploration drilling as high potential.
