Dia Bras Continues to Intersect High-Grade Massive Sulfides at Bolivar: 9.70 Meters of 3.56 % Copper and 35.30 % Zinc

MONTREAL, QUEBEC--(CCNMatthews - Oct. 26, 2006) - Dia Bras Exploration Inc. ("Dia Bras" and or the "Company")(TSX VENTURE:DIB) is pleased to announce additional high-grade drill intercepts from its underground drilling program at the Bolivar Mine in the State of Chihuahua, Mexico. The best intersection returned 9.70 m grading 3.56 %Cu, 35.30 % Zn and 29.30 g/t Ag.

The drill holes were drilled from the mine's Level 6. Holes DB06BM034, 35 and 36 tested the down-dip extension around level 7 of the Rosario and Rodolfo zones, which are elongated on a NW strike. Holes 34 and 35 cut the target skarn horizon but encountered low metal concentrations.

Hole DB06BM036 cut from 88.25 m to 109.5 m a 21.25 m section grading 0.3% Cu and 4.2% Zn, including a 3.0 m section from 97.5 m to 100.5 m of 0.2% Cu and 8.3% Zn. Hole 36 seems to have cut the same mineralized zone intersected by surface hole 168 that cut from 134 m to 144.5 m a 10.5 m section at 0.19% Cu, 7.8% Zn and 35.4 g/t Ag (see news release dated September 29, 2006).

A second set of three (3) underground holes collared from level 6 tested the Fernandez Trend. Hole DB06BM037 and 38 tested the depth extension around level 7 of the Fernandez with the following results:

Hole DB06BM039 tested the Fernandez zone on the level 6 in front of the actual drift and intersected from 40.7 m to 50.4 m a 9.7 meter section of very-high-grade massive sulfides grading 3.56% Cu, 35.3% Zn and 29.3g/t Ag.

This intersection of hole 39 extends the Fernandez high-grade mineralized zone further to the SE along the Fernandez trend, and additional drilling is in progress.

Surface drilling continues to test the Bolivar Sur skarn in the El Gallo area towards the Increible in order to define more Cu-Au-Ag-Fe mineralization. Three drill rigs are working and a compilation of the latest results will be published shortly.

Mr. Andre St-Michel, engineer and Executive Vice-President of Dia Bras, is the qualified person within the meaning of NI43-101.

Method of analysis

The core samples were analysed by atomic absorption at the Company's Malpaso lab, with the exception of the samples from hole 39 that were assayed at ERSA Global Laboratory at their facilities in Torreon, Mexico.
