TORONTO, Oct. 20, 2011 /CNW/ - Volta Resources Inc. ("Volta" or the "Company") (TSX: VTR)
announces the results from the third phase of its drilling program at the Nassara prospect, on its 100% owned Danyoro permit, in southwestern Burkina Faso, West Africa.
The reported drill results, comprising 44 drill holes (7,334 metres), represent the first part of a 15,000 meter drilling program which aims at systematically testing three wider and higher grade sections along the 2.2km of strike identified so far along the Nassara Main Zone (Nassara MZ) as well as extending the drilling depth to 150 vertical metres. In addition, scout drilling is being undertaken along strike on the recently identified northern (3.5km) and southern (2km) extensions of the Nassara MZ (see News Release of June 8th, 2011) as well as along a series of parallel shear structures, including Nassara SW (see News Release of September 14th 2011).
The highlights from the drilling program include (see Figure #1):

Kevin Bullock, Volta's CEO, said," Not only are these results notable in themselves they have provided us with clear evidence of favourable mineralization that we will be pursuing in our continuing drilling."
The holes were drilled to lengths of up to 270 meters, all inclined at -60° to the north-east. In all, 7,315 regular drill samples and 995 control samples (standards, duplicates and blanks) were submitted to the BIGS laboratory in Ouagadougou, Burkina Faso. Volta's sampling and assay procedures included QA/QC elements that employed the inclusion of certified standards and blanks.

Notes on Table 1:
- Intervals are core length. True width is unknown at this time.
- Intersections are based on a 0.30 g/t Au cut-off with no top cut applied.
- Internal dilution (less than 0.30 g/t Au) has been carried to a maximum (Maximum Internal Dilution) of 3m except for NRC40 (56.0-21.0m) and S19N (176.0-188.8m) where the maximum dilution has been set at 4m and for S20N (164.0-179.0m) where it has been set at 5m.
- The intersections listed in the table represent sections of at least 3m in excess of 0.5g/t Au or 2m in excess of 1g/t Au.
- In order to highlight high grade core zones, a 1.0 g/t gold cut-off with a Maximum Internal Dilution of 2m has been used.
- Where core losses were reported in the mineralized intercepts, the width of the entire mineralized intercept is reported at the weighted average grade of the remaining samples
- The intersections represent sections drilled by reverse circulation (RC) and/or core drilling (see Table 2).
- The RC portions of the drill holes were generally sampled at 1-m intervals. Dry samples were riffle-split to provide 2 kg samples sent to the laboratory. Wet samples were dried in the field, then riffle-split in the same way. The cored portion of the drill holes were generally sampled at one meter intervals and cut in half using a diamond saw. Half-core is archived at the core storage facility on site while the other half was sent to the laboratory.
- Samples were sent to BIGS Laboratory in Ouagadougou for standard preparation followed by Fire Assay on a 50g charge.
- Certified standards were inserted every 15 samples, field duplicates (in the RC portions) about every 25 and blanks about every 25 samples. The blanks, certified standards and duplicate assays confirm that all assays used to compile the intersections quoted here have passed Volta's rigorous QA/QC checks.
The drilling confirmed the presence of multiple parallel mineralized shears and confirmed the depth extension of the mineralization. The shears are part of a larger regional shear system extending in excess of 100km from Batié in the Southeast to Gaoua in the North. The mineralization occurs in proximity to the contact of mafic rock formations (volcanoclastics and/or volcanics), which constitute the hanging wall, and a sedimentary unit (schists), constituting the footwall. Drilling also appears to confirm that the mineralization exhibits higher grades and improved widths in discrete zones along strike, currently interpreted as being northwesterly plunging shoots with a surface footprint ranging between 300m and 600m along strike. The mineralization is related to intensive silicification (local quartz veining) and sericitization, carbonation and weak sulphidation.
The program was interrupted in late August, due to the onset of the seasonal rains. It is planned to resume drilling as soon as access to the area permits, probably in mid to late November.
