TORONTO, ONTARIO--(Marketwire - Dec. 31, 2010) -
Dia Bras Exploration Inc. (TSX VENTURE:DIB) ("Dia Bras" or the "Company") is pleased to report that drilling continues at its La Cascada target, which is a high-sulphidation gold system at its wholly owned Bolivar Property in southwestern Chihuahua State, Mexico. Drilling is targeted on near-surface, coincident strong chargeability (IP) and resistivity zones detected during Titan 24 survey contracted to Quantec Geoscience of Toronto, Ontario, which was conducted during August 2010. Only three survey lines could be completed in this area of rugged terrain: a 1,000-m-long N-S line and two E-W lines (800 and 900 m), which resulted in detection of three significant anomalies - all of which are associated with anomalous grades of gold in outcrop (see press release of August 25, 2010). La Cascada is the eastern-most area of a gold anomalous zone that trends NE-SW through La Sidra to Reyna de Oro >http://www.diabras.com/files/media/89186_La%20Cascada%20Exploration%20Model.pdf, which required constructing a drill access road 2.2 km long on the top of Cascada ridge because of its very steep sides and limited locations for drill sites. The geophysical survey covered less than 10% of the La Cascada-La Sidra area >http://www.diabras.com/files/media/96ae8_La%20Cascada%20Updated_Samples_Database%20Validated.pdf, while partial results are available for DCA10B004




Method of Analysis




Samples were prepared at the ALS Chemex lab facility in Chihuahua, Mexico, and analyzed by ICP and AA methods at their facilities in Vancouver, Canada. Diamond drill samples sent for analysis consisted of half NQ-size and BQ-size diamond core split on site, prepared by the ALS Chemex sample preparation laboratory in Chihuahua, Mexico, and assayed for Au by 50 g fire assay with AA finish, and for Ag by AA on 50 g split sample at the ALS Chemex North Vancouver Laboratory. Assays for Pb, Zn and Cu are processed by Induction Coupled Plasma (ICP) at ALS Chemex.
