Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company") is pleased to announce more high grade silver intersections from its ongoing drill program on the Cusi property, located in the State of Chihuahua, Mexico. 

HOLE DC07B101-B
Hole DC07B101-B was drilled to test the main, SW-dipping Promontorio vein (Vein “A”) and cut the vein 20 metres above Level 7(see press releasea of May 8, 2007) where it encountered 8.3 Kg of silver over a drill width of 1.5 metres, which represents about 1.0 metres true width.  This interval is within a 9.0 metres drill width (about 6 metres true width) that averages 1.65 Kg of silver.  The hole also encountered two additional zones of veining further down the hole that are interpreted to be from NE-dipping.

Drilling at Promontorio continues with one of the company’s diamond drill rigs, while a second rig continues to drill the San Marina – San Antonio structure (see below) and another rig is drilling the Santa Edwiges mine main structure along strike and down dip.

HOLE DC07B100
Hole DC07B100, which was drilled to test the Santa Marina structure, intersected a 1.5 metre section averaging 0.31 g/t Au, 777 g/t Ag, 0.17 Cu, 1.62% Pb and 1.63% Zn, as well as a 4.5 metre section that assayed 0.06 g/t Au, 10 g/t Ag, 0.2% Cu, 1.48% Pb and 2.12% Zn. View the section

From	To	Width	Au (g/t)	Ag (g/t)	Cu (%)	Pb (%)	Zn (%)
66.0	67.5	1.5	0.31	777	0.17	1.62	1.63
268.5	273.0	4.5	0.06	10	0.02	1.48	2.12

Comments
These results are highly encouraging in light of the on-going 25,000-metre diamond drilling program.   Up to present, close to 9000 metres of core drilling have been completed on the Cusi Project.  Additional drilling will aim at continuing defining the resources potential of the major Ag (Zn-Pb) vein structures of the Promontorio, Santa Marina –San Antonio and Santa Edwiges mines, all historical producers. The high grade of silver in Hole 101-B is consistent with the historical data previously reported (May 8, 2007) that indicate significant amounts of un-mined silver mineralized rock in the Promontorio mine.
