Dia Bras Announces High Grade Silver and Gold Drill Intercepts from its Drilling Program at its Cusi Project
Montréal, Québec, - June 3, 2008 -
Dia Bras Exploration Inc. (TSX-V: DIB) is pleased to report on its on-going drilling program at the Cusi silver district. Click here to view the tables of individual assays from the drilling holes.
The objectives of the on-going drilling program at Cusi are to upgrade the resources in the Santa Edwiges and Promontorio sectors, as well as targeting individual structural corridors identified during the mapping program of 2007.
To support the resource evaluation and to complement the surface drilling program, Dia Bras initiated an underground drilling program similar to the Bolivar ongoing underground program. This program has the objective to follow up mineralized zones exposed at the Santa Edwiges and Promontorio structures from the surface drilling. The results of all the drilling performed until March 31, 2008 at Cusi were included in the resource calculation and can be found on Dia Bras website. Since April 2008, more than 2882 metres of surface (2142m) and underground (740m) drilling have been completed.
One hole drilled before April with spectacular results, hole DC08M23 was not included in the resource estimates of March due to the complex structural pattern.
SANTA EDWIGES - San Antonio – San Marina Sector
The underground drilling has allowed Dia Bras to delineate high-grade ore shoots along the Santa Rosa zone and along the Santa Marina trend.
In this area, high grade silver and gold mineralization is associated with zinc and lead mineralization. The best intersection was observed in hole DC08M023, which intersected 1345 g/t Ag, 14.05 g/t Au, 1.10% Zn, 1.60% Pb and 0.1% Cu, over a core length of 1.0 metre (true width estimated at 0.85 metre). Other high grade intersections include 1235 g/t Ag, 0.34 g/t Au, 1.40% Zn, 9.20% Pb and 0.20% Cu, over 1.0 metre core length (0.75 metre true width); 400 g/t Ag, 1.3 g/t Au and only a trace of sulphides over 1.5 metre core length ( 1.0 metre estimated true width) in hole DC08M27; and 43 g/t Ag, 4.67 g/t Au, 0.7% Zn, 0.8% Pb and 0.1% Cu over 1.5 m core length (1.1 m true width) in hole DC08M26.
A very rich sulfide zone was also encountered in the same area in hole DC08M25, which intersected 853 g/t Ag, 0.11 g/t Au, 16.6% Zn, 25.4% Pb and 0.2% Cu over a core length of 0.9 metres (true width of 0.75 metre) and in hole DC08M29, which intersected 130 g/t Ag, 0.37 g/t Au, 6.70% Zn, 11.8% Pb and 0.1% Cu over a core length of 3.0 metres (2.73 metres true width).
As previously reported, the Santa Edwiges – San Antonio – San Marina sector consists of multiple fracture-filled quartz-carbonate veins containing high sulphide contents that are typical of the middle portion (Pb-Zn) of a zoned, low-sulphidation epithermal vein. This middle portion of the vein transitions upwards to the precious metal (Au, Ag) portion of the vein.
Surface drilling resulted in the Promontorio sector reveals 503 g/t Ag, 0.1 g/t Au, with a trace of sulphide over a core length of 1.5 metres (estimated true width of 0.8 metre).
