Dia Bras Reports High Grade Gold at Surface on Its La Cascada Prospect of the Bolivar Property

10:30 EST Monday, January 25, 2010

MONTREAL, QUEBEC--(Marketwire - Jan. 25, 2010) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) is pleased to report that it has received high grade gold assays from surface channel samples collected in its initial exploration program on the La Cascada prospect of its Bolivar property. La Cascada lies only 2.5 km south of Cieneguita, where Dia Bras has its camp, offices and maintenance facilities for its Bolivar mine operations.

Commenting on the results, Daniel Tellechea, President of Dia Bras, stated, "We are encouraged by the high grade results discovered at surface outcrops that are as high as 15 grams per tonne over a 3 metre channel. This prospect is near our existing infrastructure and lies within the prolific Sierra Madre gold-silver belt of northwestern Mexico that hosts several multi-million ounce gold deposits."

Bolivar has never been explored for gold by modern methods, yet the property is surrounded by several historical gold producing mines and currently well known deposits, such as Goldcorp's El Sauzal mine (1.2 million ounces of gold produced), located 12 km southeast of the prospect and Coeur's Palmarejo deposit (1.1 million ounces of gold plus 88 million ounces of silver), located 50 km to the northwest (see attached Regional Map (http://www.diabras.com/en/newscenter/2010/Cascada%20Regional%20Location.pdf)).

Geology

The La Cascada prospect is underlain by an extensive and thick sequence of pyroclastic breccias and agglomerates, including lapilli tuff, landslide mega-breccias, and tuff breccias mixed with andesitic flows, all derived from andesitic volcanism. The basal andesitic flow contains volcanic blocks and bombs, lapilli and ash tuff.

Detailed geologic mapping and sampling are in progress with the objective of identifying drill sites.

Mineralization

From the La Cascada central zone towards the north - northeast, gold anomalies occur along contact zones of discordant veins and veinlets of limonite, sponge limonite and hematite with pervasive quartz and fine-medium pyrite (see attached La Cascada Prospect Au Values (http://www.diabras.com/en/newscenter/2010/Cascada%20Prospect%20-%20Au%20values.pdf) and Anomalies maps (http://www.diabras.com/en/newscenter/2010/Cascada%20Prospect%20-%20Anomalies.pdf)). In addition, a stratiform zone is hosted by intensely argillized, pyroclastic breccia and infill tuff breccia bounded by interlayered andesitic flows.

From the central zone towards the southwest is a topographically higher area where zones of veining with disseminated sulphides (galena, sphalerite, chalcopyrite) occur.

Extensive argillic alteration (kaolinite - quartz - hematite - limonite) occurs over a 100 hectare area with pervasive quartz, fine-medium pyrite and partial silicification of the matrix.

To date, two possible gold-related assemblages have been identified:

1. Quartz - Pyrite - Sericite - Alunite? - Dickite?: Mainly in altered pyroclastic breccia zones and infill breccia tuffs forming a stratabound altered unit cut by anastomosed veins/veinlets with sponge limonite, limonite, hematite and quartz.

2. Sponge Limonite - Jarosite - Hematite - Goethite: Mainly forming halos in fractures or fillings forming veins and veinlets crossing altered host rocks.

This is the first systematic channel sampling on the prospect that covers an area of 2,000 by 3,000 metres. Table 1 below shows selected results from sampling at La Cascada. Complete results are given in the accompanying maps that show sample locations and alteration patterns.

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 done by Induction Coupled Plasma (ICP) at ALS Chemex.
