Dia Bras: First Technical Report on Cusi

Current exploration program includes 20,000 meters of diamond drilling for 2007

MONTREAL, QUEBEC--(CCNMatthews - Jan. 31, 2007) - - Dia Bras Exploration Inc. (TSX VENTURE:DIB) is pleased to receive the first technical report on its Cusi silver project in Northern Mexico. The NI 43-101 report prepared by Scott Wilson Roscoe Postle Associates Inc. (Scott Wilson RPA) and dated December 22, 2006 concludes that there is good potential for economic silver-gold mineralization on the Cusi property. The Company's current drilling program of 20,000 m of diamond drilling is being conducted on the northwestern portion of the project where 12 inactive silver mines are located. The objective of the drilling is to test the down-dip and strike extensions of the silver veins in these mines as well as define sufficient mineralization so that an initial resource calculation can be done.

According to Scott Wilson RPA, the Cusi project contains several former silver-copper-zinc-lead-gold producers and on-going exploration has the objective to extend known zones of silver mineralization along the strike of the structure that hosts the La Bamba open pit as well as the San Miguel mine, the La India mine and the Santa Edwiges mine. Recent drilling near the La Bamba open pit has intersected mineralized zones that are interpreted to be down-dip extensions of mineralization exposed at the open pit. The most prominent of these are:

- 113g/t Ag over 22.5 m in hole DC06B37

- 981 g/t Ag over one meter in hole DC06B30

Scott Wilson RPA is of the opinion that these zones are open along strike and warrant further drill testing. The complete Technical Report will be filed on SEDAR and posted on Dia Bras' website (www.diabras.com).
