DIA BRAS ANNOUNCES RECORD MONTH OF PRODUCTION OF COPPER AND ZINC CONCENTRATES FROM THE BOLIVAR MINE

Montréal, Québec, - December 9, 2005 -

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

During November, the combined zinc and copper concentrate production amounted to 1,390 dry metric tons (“DMT”) (364 DMT of copper concentrate and 1,026 DMT of zinc concentrate) for a production value of over US$900,000, as the company benefits from the constant rise of the copper and zinc market price. This represents an increase of 38.4% over the October production value.
These production figures have been achieved even though the ore throughput at the Malpaso mill remained under the mill’s full capacity due the transportation problem encountered in October which also affected the start of the November production. However, the mill ran close to full capacity during the last two weeks for a final November throughput of 6,027 tonnes, which represents an increase of 26.6% over October.

The monthly average grades of ore processed where 2.18% for copper and 10.46% for zinc, a slight reduction from October’s grades of 2.43% Cu and 12.45% Zn, due to mining at the fringe of the Brecha Linda.

November average rates for copper and zinc were 76.78% and 91.92% respectively. Recovery rate is improving and the Company anticipates reaching 85% for copper by the end of the year.

The Company expects mill throughput of about approximately 5,200 tonnes in December due to seasonal shutdown of the mill for the Christmas period, with grades similar to those of October and November.
