Dia Bras Intersects 188 g/t Silver Over 38 Meters at Cusi

MONTREAL, QUEBEC--(CCNMatthews - Nov. 2, 2006) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) ("Dia Bras" and or the "Company) is pleased to announce an intersection of 38 meters grading 188 g/t Ag as part of the latest exploration results from its Cusi silver Project in Chihuahua State, Mexico.

Hole DC06B030 drilled to test the La Bamba open pit cut from 35 m to 78 m, a mineralized breccia of 38 metres grading 0.10 g/t Au, 188.48 g/t Ag, 0.02 % Cu, 0.28 % Pb and 0.14 % Zn. Included in this interval are a section of 7 meters at 390 g/t Ag and a one-meter section at 981 g/t Ag.

La Bamba and San Miguel are inactive mines that are optioned from Pershimco Resources, whereby Dia Bras can earn 70% interest (see news release dated May 31, 2006).

La Bamba is an open cut that follows a northeastern trending 30-meter thick breccia structure with a steep southeastern dip. The pit measures 100 meters long by an average of 20 meters wide and up to 30 meters deep. The structure, which includes La Bamba and San Miguel, has a known strike length of 600 meters. This mineralized structure has been mapped by Andre Ciesielski, Ph.D., and identified for an additional 1000 meters onto the Dia Bras 100% owned land package.

The following drill holes have been collared to test the extension on strike and at depth of the breccia. One drill is on site and a second one will be mobilized to accelerate the evaluation.

Although the program has only been in progress for five months, significant silver values have been identified and material from various portions of the inactive mines will be processed at the Company's Malpaso mill beginning in November 2006. These early results support the interpretation that significant silver mineralization remains to be mined in the district.

The Company commissioned an independent 43-101 technical report to Scott Wilson Roscoe Postel, expected to be completed by the end of the year.

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

All drill samples were assayed by ALS Chemex, North Vancouver, Canada with the exception of the samples from hole DC06B40 and 42 that were assayed at ERSA Global Laboratory at their facilities in Torreon, Mexico, using the using ICP method, and hole DC06B37 that was analysed by atomic absorption at the Company's Malpaso lab.
