Dia Bras Intercepts 7 Meters Of 6.2% Copper and 21.7% Zinc at Brecha Linda

MONTREAL, QUEBEC--(CCNMatthews - Oct. 13, 2005) - Dia Bras Exploration (TSX VENTURE:DIB) is pleased to announce results of its drilling program at the Bolivar Cu-Zn Project. Hole 139 cut 7.0 meters of massive sulphide averaging 6.2% copper and 21.7% zinc.

Drill holes 139, 141 and 143 were drilled in advance of the Company's production stopes to expand the Brecha Linda zone in the immediate mining area. These holes penetrated massive sulphide mineralization within 20 meters of the area currently being mined, demonstrating the continuity of the high-grade copper-zinc zone.

(i) previously announced

The massive sulphides in these holes are similar to those in Hole 135 drilled 170 meters to the southeast (previously announced 10.7 meters of 26.8% Zn and 0.85% Cu), which the company infers to be the southeastern extension of the Brecha Linda.

"These results demonstrate that the Company has reached the first portion of an extensive copper-zinc mining zone at the Bolivar mine. The grades being produced at our mill are expected to increase significantly as more of the Brecha Linda zone is mined", said Dr. Thomas Robyn, the Company's Chairman and CEO.

Mr. Andre St-Michel, engineer and Executive Vice-President of Dia Bras, is the qualified person within the meaning of NI43-101. Drill samples were assayed by ALS Chemex Labs Ltd.
