DIA BRAS ANNOUNCES RECORD RESULTS IN OCTOBER FROM ITS PILOT MINING PROGRAM AT BOLIVAR

Montréal, Québec, - November 2, 2005 -

Dia Bras Exploration Inc. (DIB-V) (Dia Bras or the "Company") is pleased to announce a record month in terms of production and sales of concentrate at its pilot-mining program at the Bolivar mine in Chihuahua Mexico.

During October, the combined zinc and copper concentrate production of 1,212 tons (297 dry metric tons of copper concentrate and 915 dry metric tons of zinc concentrate) resulted in total sales of US$650,000. This represents an increase of 40% versus the monthly results of the production value of the previous three months.

These numbers have been achieved although ore throughput at its Malpaso mill facility was under capacity due to transport problems which were encountered during the month. Corrective measures were immediately taken.

After having increased its mill capacity during the summer, the Company realised its most productive months to date in August and September with respective throughputs of 6,498 and 6,624 tonnes of ore. However, as grades of ore mined during these two months (coming from development ore) were still below expectation, average concentrate production amounted to only 866 tons.

Due to the much higher grade material mined from the Brecha Linda and processed in October (a monthly average of 2.43% Cu and 12.40% Zn), the Company recorded its record month. At the same production rate as the previous two months total production would have exceeded US$900,000.

Recovery is improving and the Company anticipates reaching 85 % for both copper and zinc by the end of the year.

With a plant capacity of 7,500 tonnes per month and benefiting from the high copper and zinc market prices, the Company expects November production and sales results to improve again significantly.
