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 which is 100% owned by the Company.

Hole DC07B91, of which partial assay results had been previously reported (see press release, April 18th, 2007) and that was drilled to test the section under the western half of the 100% Dia Bras owned San Antonio Pit, intersected a further 40.0 metre section averaging 0.1 g/t Au, 101 g/t Ag, Cu, 1.78% Pb and 2.09% Zn, including a 6.0 metre section that assayed 0.2 g/t Au, 336 g/t Ag, 0.1% Cu, 2.1% Pb and 1.3% Zn and a second 7.5 metre section that assayed 0.1 g/t Au, 119g/t Ag, 0.2% Cu, 5.1% Pb and 8.4% Zn.

 
HOLE DC07B91

From	To	Width (m)	Au (g/t)	Ag (g/t)	Cu (%)	Pb (%)	Zn (%)
197.0	237.5	40.5	0.07	101	0.08	1.78	2.09
Including  197.0	203.0	6.0	0.20	336	0.1	2.1	1.3
and 212.0	216.5	4.5	0.20	217	0.2	3.8	2.2
and 230.0	237.5	7.5	0.1	119	0.2	5.1	8.4

Hole DC07B91 tested the down dip extension of the western portion of the San Antonio Pit. The core angle is approximately 35 degrees and should result in a true thickness of the mineralized zone which could vary from 10 to 15 metres, because the dip of the mineralized structure as extrapolated from surface varies from vertical to 70-80 NW.

In addition, hole DC07B92, drilled about 5 metres south of the shaft to test the 100% Dia Bras owned Santa Marina Vein in its central section, intersected two zones of gold-silver mineralization.  The first zone cut 3 metres of 0.3 g/t Au, 372 g/t Ag, and traces Cu, Pb and Zn.  The second intersection is a mixture of broken core and mineralization possibly left in an old pillar of the mine. It contains a 3.0 metre section of 2.30 g/t Au, 150 g/t Ag, trace Cu, 0.3% Pb and 0.78% Zn.  The recovery in this last section was just over 50%.  The mineralized intersection stopped in an old stope, which is estimated to be 4.4 metres in core length. The next intersection of 3.0 metres intersected low grade mineralization possibly representing the hanging wall of the mineralization.

From	To	Width (m)	Au (g/t)	Ag (g/t)	Cu (%)	Pb (%)	Zn (%)
122.0	125.0	3.0	0.3	372	0.1	0.4	0.2
and 218.0	221.0	3.0	2.30	150	tr	0.3	0.78

Assay results are pending for hole DC07B94, drilled on the same setup at a steeper angle to test the down dip extension of the vein.

Hole DC07B93 was drilled to test the central section of the Santa Marina Mine, 20 metres north of the shaft, and intersected numerous zone of mineralization, including a 3 metre section that assayed 582 g/t Ag.

Method of analysis and quality assurance-quality control
Diamond drill samples sent for analysis consist of half NQ size diamond core split on site, prepared by ALS Chemex samples preparation laboratory in Chihuahua, Chihuahua State, Mexico, and assayed for Au and Ag by 50 g fire assay with AA finish at the ALS Chemex North Vancouver BC Laboratory.  Assays for Pb, Zn and Cu are done by Induction Coupled Plasma (ICP).  The quality assurance-quality control (QA-QC) of DiaBras has been described in details in Scott Wilson RPA 43-101 report of December 2006.

The technical content of this news release has been approved by François Auclair, P.Geo. and Vice-President, Exploration of Dia Bras, a Qualified Person as defined in NI43-101.
