TORONTO, ONTARIO--(Marketwire - Dec. 29, 2010) -Dia Bras Exploration Inc. (TSX VENTURE:DIB) ("Dia Bras" or the "Company") is pleased to report assay results from the La Verde high-sulfidation gold prospect at its wholly owned Batopilas Property in Chihuahua State, Mexico. The Batopilas Property is located southeast of the Company's wholly owned Bolivar Property and is located less than 20 km to the east of Goldcorp´s El Sauzal gold mine and within one of the most important gold mining belts in the Sierra Madre Occidental of Northern Mexico.
"These results emphasize our strategy to explore and develop significant gold prospects as part of the Company's long-term growth plan," stated Daniel Tellechea, President and CEO. "These sample assays demonstrate that the large alteration area of La Verde, covering over 25 km2, is a strong, high-sulphidation gold system related to porphyry intrusions in the area. We have high grades of gold in outcrop over two structural trends, as well as highly anomalous stream sediment samples that indicate a gold mineralized area in the core of the large argillic alteration area. We believe that this area is an important prospect, and we are proceeding with additional sampling and mapping with the objective of locating drill targets that will be drilled in early 2011."
Complete results are given in the accompanying maps that show sample locations and alteration patterns.
Figure 1 (https://www.diabras.com/files/media/b6973_Chihuahua%20Regional%20Projects%20and%20Mines%20on%2028%20Dec%202010.pdf) is a map showing La Verde's location relative to other mineral deposits and mines in the region. Figure 2 (https://www.diabras.com/files/media/264e1_La%20Verde%20_%20201012-%20regional%20map-1.pdf) shows the overall La Verde area and the location of the Tres Hermanos mine, a historic gold producer at a grade of 16.35 g/t gold from 1916-1936 (Servicio Geológico Mexicano - SGM).
The La Verde trend, one of two NW-trending sets of gold-bearing veins, is on strike from the Tres Hermanos Mine. The Dia Bras exploration team believes La Verde trend is the same structure that hosts Tres Hermanos Mine. The trends are dominated by quartz veins and stockworks, sulphide minerals, oxide boxworks and visible copper mineralization. Figure 3 (https://www.diabras.com/files/media/20ae0_La%20Verde%20Veins%20Exploration%2027%20Dec%202010.JPG) shows a close-up of the two vein sets, the La Verde and Los Frailes trends, and the significant gold grades found in them, up to 9.0 g/t Au in the La Verde trend.
In addition, results from stream sediment samples show that two secondary streams draining a ridge cored by a silicic dome are highly anomalous in gold, up to 262 ppb, indicating significant exploration potential in that area. The 163 and 368 ppb Au samples were collected from the main stream and do not identify a particular area. A comprehensive stream sediment sampling program that will cover the argillically altered area is scheduled to begin in January, with the objective of collecting samples at a density of one sample per square kilometre.
Table 1 below shows selected results from samples collected from the more altered rocks at La Verde. The complete list of the assay results from the recently received samples is in the (https://www.diabras.com/files/media/f526d_La%20Verde%20Sample%20Assay%20Spreadsheet%2027%20Dec%202010.pdf) accompanying table.

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.
Quality Control
The quality assurance-quality control (QA-QC) program employed by Dia Bras has been described in detail in both RPA's NI 43-101 reports of December, 2006, at Cusi and October, 2005, for Bolivar.
The technical content of this news release has been approved by Thomas L. Robyn, Ph.D., CPG, RPG, a Director of Dia Bras, a Qualified Person as defined in NI 43-101.
