Dia Bras drills 9.3 metres of 1.8% Cu and 2.5 metres of 18% Zn at El Gallo at its Bolivar Property

Montréal, Québec, - October 15, 2007 -

Dia Bras Exploration Inc. (DIB-V) is pleased to announce drill intercepts in the El Gallo area from its ongoing surface exploration drilling program at the Bolivar property in the State of Chihuahua, Mexico.

Drilling in the El Gallo area continues to intersect widespread disseminated copper mineralization in the magnetite-bearing Lower Skarn and high grade zinc in the Upper Skarn.  The drill holes reported here postdate the resources calculation (press release of September 25th, 2007).  On-going exploration by Dia Bras in the El Gallo area continues to extend the mineralization in both Lower and Upper Skarn horizons as well as in other areas of the property, which encompass some 75 km2.  The program at El Gallo is expanding and better defining Inferred Resources in this area.  Dia Bras intends to update its resource base as drilling progresses.

“The tabular and predictable nature of the Lower Skarn allows us to do in-fill and step-out drilling with a high degree of success and we will continue to define the volume potential of this mineralization over the next few months”, says Dr. Thomas Robyn, Executive Chairman.  “We are also very excited about the extent of the high grade zinc mineralization in the Upper Skarn at El Gallo”

Results
Drill hole DB07B201 was drilled on section 9350, vertically. It intersected numerous bands of disseminated Cu-Zn mineralization, with best assays of 1.0% Cu over 9.0 metres in the Lower Skarn.

Drill hole DB07B202, drilled on section 9325 at an azimuth of 225o and a dip of -68o intersected high grade Zn mineralization, 3.3m at 6.9% Zn and 3m at 12.4 % Zn, in the Upper Skarn and a 12.5 metre section of 1.3% Cu in the Lower Skarn.

Drill Hole DB07B205 was drilled on section 9325, at an azimuth of 700 and a dip of-750. It intersected a number of mineralized sections, including a 5.2 metre intersection in the Lower Skarn averaging 1.1% Cu.

The best intersections come from hole DC07B208, drilled on section 9350 at an azimuth of 2380 and a dip of -580, which includes 9.3 meters drill width averaging 1.8% Cu.

As of September 30th 2007, some 17,840 metres of diamond core drilling have been completed on the Bolivar project, 12,011 from surface and 5,829 from underground.  Over the past few weeks, with the end of the rainy season, productivity has increased and more drilling has been achieved. Dia Bras still intends to complete a 25,000 metres drilling program at the project this year.

Method of analysis

Samples were prepared at Chemex lab facility in Chihuahua, Mexico, and analyzed by ICP and AA methods by Chemex at their facilities in Vancouver, Canada.

Quality control
Diamond drill samples sent for analysis consist of half NQ-size diamond core split on site, prepared by 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 Chemex. The quality assurance-quality control (QA-QC) of Dia Bras has been described in detail in both RPA’s 43-101 reports of December 2006 at Cusi and October 2005 for Bolivar.

The technical content of this news release has been approved by François Auclair, P. Geo. and Vice-President, Exploration of Dia Bras, a Qualified Person as defined in NI43-101.
