Dia Bras Reports Significant Drill Intersections From the El Gallo Area, Bolivar Project and New Management Appointments
MONTREAL, QUEBEC--(Marketwire - July 29, 2008) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) is pleased to provide new drilling results from the ongoing 20,000-metre exploration program at its Bolivar project and announce new appointments to the Company's management team.
In the El Gallo area, a series of holes drilled east of the newly discovered bornite zone (ref. press release of April 8, 2008) intersected widespread copper mineralization, thus extending further east the known copper-bearing portions of the upper and lower skarns. Of particular interest is hole DB08B248 that intersected 18.1 metres core length (estimated true width of 11.6 metres) of 2.2% Cu, 0.72 g/t Au, 32 g/t Ag and 26.4% Fe in the lower skarn horizon. The first 2 metres of this interval displayed minor bornite mineralization with grades of 4.5% Cu, 52.2 g/t Ag, 1.4 g/t Au and 38% Fe. This intersection is situated approximately 60 metres ENE of hole DB07B242, which intersected 3.1% Cu over 18 metres (core length) in the upper skarn.
In the same area, hole DB08B251 intersected high gold grades with lesser copper grades that averaged 1.7% Cu, 31 g/t Ag, 4.1 g/t Au and 15.4% Fe over 2.7 metres core length (1.9 metres estimated true width) in the lower skarn.
In the western part of the El Gallo area, hole DB08B247 intersected the lower skarn over 8 metres core length (7.5 metres true width) and averages 1.3% Cu, 25 g/t Ag and 0.24g/t Au.
These intersections further confirm the extent of the lower skarn horizon to the south-east and north-west of the main El Gallo area and will allow increasing the resource base of the Bolivar project.
Bolivar Mine Area (Alta Ley)
Surface and underground diamond core drilling at Bolivar Alta Ley are aimed at continuing to define the Rosario and Fernandez mineralized trends while also identifying potential new zones of mineralization, as well as further delineating the Selena, Titanic and Rosario massive sulfide lenses.
In the Bolivar mine area, the best drill intercepts were observed in underground hole DB08BM166 that intersected 8.4 metres core length (2.2 metres estimated true width) of 5% Cu, 25.4% Zn, 29 g/t Ag and 0.07 g/t, and in hole DB08BM147 that intersected 4.7 metres core length (estimated true width of 3.0 metres) of 2.5% Cu, 6.9% Zn, 44 g/t Ag and 0.06 g/t Au, both in the Titanic zone.
Bolivar Mine Area (San Francisco)
The San Francisco zone is a newly opened underground area. A 160-metre positive ramp from Alta Ley reached this zone at the beginning of July, and definition drilling and development work will be undertaken soon. This zone was discovered in 2004 and 2005 during the surface drilling exploration program. Underground drilling has enabled the defining of a block of mineralized material that will be included in the updated resource statement that should be announced at the end of the third quarter.
The best underground intersections in this area come from hole DB08BM165 that intersected 16.2 metres core length (estimated true width of 4.2 metres) of 1.0% Cu, 8.7% Zn, 30 g/t Ag and 0.18 g/t Au. Other interesting holes in this area include DB08BM155 that intersected 3.0 metres core length (1.9 metre estimated true width) of 1.9% Cu, 0.7% Zn, 17 g/t Ag and 0.51 g/t Au.
La Montura Area
The best intersection in this area is in hole DB08250 that intersected a first zone of 2.1 metres core length (1.5 metre true width) of 4.3% Zn, 27 g/t Ag and 6.81 g/t Au, and a second zone of 4.8 metres core length (3.4 metres estimated true width) of 0.1% Cu, 4.0% Zn, 739 g/t Ag and 0.23 g/t Au in the El Val sector.
Samples were prepared at the Chemex lab facility in Chihuahua, Mexico, and analyzed by ICP and AA methods at their facilities in Vancouver, Canada. Diamond drill samples sent for analysis consisted of half NQ-size diamond core split on site, prepared by the ALS Chemex sample preparation laboratory in Chihuahua, Mexico, and assayed for Au by 50 g fire assay with AA finish, and for Ag by AA on 50 g split sample at the ALS Chemex North Vancouver Laboratory. Assays for Pb, Zn and Cu are done by Induction Coupled Plasma (ICP) at Chemex.
