Dia Bras Reports 248 g/t Silver From Bulk Sample at La Bamba Open Pit, Cusi Silver Project, Chihuahua, Mexico

MONTREAL, QUEBEC--(CCNMatthews - Dec. 12, 2006) - Dia Bras Exploration Inc. (TSX VENTURE:DIB)("Dia Bras" and or the "Company") is pleased to announce that 6,350 tonnes grading 248 g/t Ag have been extracted from La Bamba's open pit as part of the ongoing exploration program at its Cusi silver project in Chihuahua State, Mexico.

La Bamba and San Miguel are inactive mines that are optioned from Pershimco Resources Inc., whereby Dia Bras can acquire a 70% interest (see news release dated May 31, 2006) in return for work commitments extending over a 30-month period. As part of this commitment, Dia Bras has started to process a 10,000 tonne bulk sample at its Malpaso mill.

During the first week of December, a total of 6,350 wet metric tonnes (WMT) have been extracted from the existing broken material lying at the bottom of the pit. This oxidized material is being stockpiled and then transported to the Malpaso mill.

A total of 277 truck loads were necessary to build the stockpile of which 254 were sampled and assayed at the Malpaso laboratory. They returned between 40 and 880 g/t Ag. The average results for the 254 samples are the follows:



------------------------------------------------------------------------
6,350 WMT 254 SAMPLES 247.79 g/t Ag 0.17 % Zn 0.21 % Pb 0.04 % Cu
------------------------------------------------------------------------


The samples were not assayed for gold but more than 50 metallurgical tests performed on the material from La Bamba's open pit show the gold content to be approximately 0.60 g/t Au. The tests also revealed that a 70% recovery rate could be achieved for silver.

La Bamba is an open cut that follows a northeastern trending 30-meter thick breccia structure with a steep southeastern dip. The pit measures 130 meters long by an average of 20 meters wide and up to 30 meters deep. The mineralized structure, which includes La Bamba and San Miguel, has a known strike length of 1,600 meters of which the southernmost 1,000 meters lie on the Dia Bras 100% owned land package.

Rejean Gosselin, President and CEO of the Company, stated "In May and June 2006, the Company staked ground and entered into agreements to gain interest in more than 7,500 hectares of contiguous property (the Cusi Silver Mining Camp), including 12 former mines. La Bamba and San Miguel mineral lots cover one of those mines which the Company is exploring first because of its easy access and to rapidly complete its commitment. Santa Edwiges and San Nicolas also present an easy access and are part of the first phase of the exploration program carried out at Cusi. The exploration program will intensify in 2007 in order to initiate evaluation of the whole district, with the completion of a detailed airborne geophysical survey and up to 50,000 meters of underground and surface drilling."

The Company commissioned an independent 43-101 technical report to Scott Wilson Roscoe Postel, on the Cusi Silver Mining Camp. This report is expected to be completed by the end of 2006.

The technical content of this news release has been approved by Andre St-Michel, engineer and Executive Vice-President of Dia Bras, a Qualified Person as defined in NI43-101.

Method of analysis

All samples were assayed by atomic absorption at the Company's Malpaso lab.
