Dia Bras Reports More High-Grade Gold Samples at the La Cascada High-Sulfidation Gold Prospect at the Bolivar Property

10:30 EDT Tuesday, April 06, 2010

MONTREAL, QUEBEC--(Marketwire - April 6, 2010) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) is pleased to report more assay results from the La Cascada high-sulfidation gold prospect of its Bolivar property in Chihuahua State, Mexico. La Cascada is located only 2.5 km south of Dia Bras' support and maintenance facilities at its Cieneguita camp.

"These results reinforce our earlier data that show La Cascada is a significant gold prospect," stated Daniel Tellechea, President and CEO. "These latest sample assays demonstrate that the silicified and brecciated bedrock consistently returns potentially-economic grades of gold, with values in outcrop up to 7 g/t gold. We have high grades of gold in outcrop over a distance of 2,500 metres, an indication of the breadth and strength of this mineralized area. Even though results from another 35 samples from La Sidra are yet to be received, we are convinced that this area is an important prospect, and we are proceeding with a geophysical survey that will assist in defining drill targets."

Table 1 below shows selected results from samples collected from the more altered rocks at La Cascada. Complete results are given in the accompanying map (http://www.diabras.com/en/newscenter/2010/Cascada_Update.pdf) that shows sample locations and alteration patterns, and a complete list of the results from the newly-received 70 samples is in the accompanying table (http://www.diabras.com/en/newscenter/2010/La_Cascada_samples.xls).

The zone of high-sulfidation gold mineralization is characterized by an extensive zone of strong, advanced argillic alteration of the host andesite extending at least 6 km2 that contains areas of silicification, and the zone is open in several directions. The silicified zones are structurally controlled and occur as concentric zones of silicification expressed by an outer zone of granular silica replacement of andesite, an intermediate zone where silicification has destroyed feldspars and original textures, and a core zone of vuggy silica where all original features of the host rock have been destroyed. An interpretive section is available at the following link: http://www.diabras.com/en/newscenter/2010/sidra_section.pdf. La Cascada is located only 5.5 km to the NE of EXMIN's Reyna de Oro gold prospect and appears to be related to the Reyna de Oro in a long system with multiple zones of gold mineralization along the trend.

The La Cascada mineralization has characteristics similar to several multi-million ounce high-sulfidation gold deposits, such as the gold association with structurally controlled vuggy silica zones, the style of alteration zonation, association with copper and arsenic, presence of pyrophyllite, etc. La Cascada is notably similar to the El Sauzal deposit, which is located less than 20 km to the southeast and is on the same regional, NNW-trending major structural zone.

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. Samples sent for analysis were 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 done by Induction Coupled Plasma (ICP) at ALS Chemex.
