DIA BRAS: 2006 EXPLORATION RESULTS AND 2007 EXPLORATION PROGRAM ON THE CUSI SILVER PROPERTY

Montréal, Québec, - March 1, 2007 -

Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company") is pleased to report on the results of its 2006 exploration activities at the Cusi property, located in the State of  Chihuahua, Mexico, as well as on its 2007 exploration program. We have made rapid progress and we anticipate discovering a major deposit.

Dia Bras acquired the Cusi Silver Project in June 2006 by consolidating a total of 72 mineral lots covering a large land package of more than 7,900 hectares and including several producing silver mines. The Company then initiated an integrated exploration program in the northwestern part of the Project consisting of geological mapping, sampling of the open cuts, drilling, dewatering of two shafts and limited bulk sampling.

2006 results
The highlight of the 2006 program was the intersection of 35.4 kg/t Ag over 0.4 meters from La India,  and the channel sampling in Santa Edwiges that yielded 2.7kg/t Ag over 3.62 meters.

The geological mapping identified a large alteration system hosted by a thick felsic ignimbrite near a fault contact with a younger andesite. The two major directions of the mineralized structures are ENE and WNW.

A total of 11,700 meters of drilling was completed in the Cusi camp, of which 5,500 meters were drilled at San Miguel and La Bamba and the rest equally split between Santa Edwiges/San Nicolas and La India. The most significant drill results are presented in table 1 below. Dia Bras holds an interest of 50% and an additional 20% in the La Bamba and San Miguel properties from Pershimco (see press release, May 31, 2006). The other 10 inactive mines are 100% owned by Dia Bras.

In addition to the drilling at La Bamba, several rock composite samples were collected from the open pit in preparation for a test bulk sample and returned very encouraging results from oxide material (see press release of December 12, 2006).

Most of the holes drilled at Santa Edwiges stopped in highly fractured zones and could not reach the intended targets. However, the underground mapping and sampling program returned significant results as announced on January 22, 2007. The cleaning and opening of the old workings at Santa Edwiges is being performed to prepare a test bulk sample of sulfide material to be treated at the Company’s newly expanded 850 tpd Malpaso mill.

The 2007 program
The objectives of the 2007 program are two-fold: define sufficient mill feed for the Company’s Malpaso Mill and discover a high-value deposit.

These tasks will be undertaken by continuing the program put in place in June 2006.  The program will consist of geological mapping, definition, extension and exploration drilling as well as dewatering, rehabilitation and development of the inactive mines.

The regional scale mapping will be extended to the rest of the property, while local detail mapping and sampling of the mineralized structures and veins will be completed.

T hree surface drill rigs will perform the 25,000 meters of drilling planned for 2007. A total of 11,000 meters will be drilled to test new targets identified by the geological mapping program in 2006 and 2007, including 2,000 meters to further explore La India. The remaining meters will be drilled at San Miguel-La Bamba and in the area of Santa Edwiges- San Antonio- Santa Marina (see map attached). In addition, two underground drills will test the extension of the zones found at Santa Edwiges.
