Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company") is pleased to announce more high-grade drill intercepts from its underground drilling program at the Bolivar Mine in the State of Chihuahua, Mexico.

Drilling of both the Fernandez and the Rosario trends returned high-grade intercepts.  Moreover, along the recently discovered Selena breccia zone, part of the Fernandez trend, an intersection yielded 21.0 m grading 3.3% Cu and 22.3% Zn. Several holes in this lens returned high grades of copper and zinc. Furthermore, four (4) holes intersected massive sulfide in the Rosario trend, where the best section returned 8 metres grading 33.8% Zn and 0.7% Cu. The Fernandez and Rosario lenses are part of the Upper Skarn Unit at Bolivar.

“These drill results support our interpretation that massive, high-grade mineralization in both the Fernandez and the Rosario trends continues along strike and to depth below our present workings,” said Dr. Thomas L. Robyn, Executive Chairman, “These new drill intercepts open a large exploration area for the discovery of more high-grade sulfide mineralization at the Bolivar Mine. The Bolivar mineralizing system was a powerful system and we have only begun to probe the fringes of it.”

UNDERGROUND DRILLING
The underground holes were drilled from the mine’s level 6. Holes DB06BM066 through 71 tested the downward extension of the Selena breccia in the Fernandez zone, which trends ESE.

Drilling of the Selena Breccia produced the following results:

The Selena breccia plunges to the ESE and is contained within an extensive zone of skarn-hosted disseminated to semi-massive sulfide mineralization related to the Fernandez trend.  The limits of the high-grade breccia have not been drilled off, and the massive mineralization remains open down-plunge and may be part of a major feeder pipe.

Drilling from level 6 of the Rosario zone also encountered skarn-hosted mineralization and produced the following results:

DB07BM061	0.0	16.5	16.5	0.4	14.7	0.02	6.03

These results, combined with results from previously reported (see press release, February 27, 2007) surface drilling, show that massive sulfide mineralization continues to depth along the Rosario-Rodolfo trend. The exploration team is successfully testing the potential of what appears to be a rhomboidal structural pattern (see attached figure) containing the high-grade massive sulfide mineralization of the Rosario/Fernandez/Brecha Linda trends.  Repetition of this pattern is expected to occur along the entire extent of the Upper Skarn Horizon, a very fertile trend stretching over 3.0 km. This concept is supported by the high grades of copper and zinc mineralization that occur at El Val, La Pequeña and La Narizona (see press release, December 14, 2006).
