Volta Resources Announces New Porphyry Copper-Gold Mineralization at Dienemera, Gaoua Project, Burkina Faso

19.12.2012  |  CNW

- Intersects 100.0 meters at 0.47% copper-equivalent -

- And 61.0 meters at 0.52% copper-equivalent -

TORONTO, Dec. 19, 2012 /CNW/ - Volta Resources Inc. ("Volta Resources" or the "Company") (TSX: VTR) announces additional results from its recently completed 131 hole, 13,528 metres, reverse circulation (RC) and diamond drilling (DD) program on its Gaoua copper-gold project, located in southern Burkina Faso, West Africa (see Figure 1). The program aimed at testing for continuity and extensions, both along strike and laterally, of the known copper-gold mineralization at Gongondy and Dienemera. Gongondy and Dienemera are two of several copper-gold porphyry targets on the Gaoua Project where sufficient drilling has been undertaken to estimate a maiden NI43-101 compliant resource comprising more than 1 million ounces of gold and 720 million pounds of copper (see table 3).

This press release includes the results from 62 reverse circulation holes, totalling 5,039m of drilling, drilled on the Dienemera prospect, from Section 1147200N to Section 1148550N. The drilling campaign at Dienemera aimed specifically at testing an area located some 500m east of the main orebody where previous scout drilling had intersected copper-gold mineralization, at searching for extensions along strike and along the eastern margin of the main orebody and at infilling areas of previous wide-space drilling.

The drilling traced the copper-gold mineralization, located 500 m east of the main deposit, for over more than 250m along strike, parallel to the main orebody (see Figure 2). This new mineralized body remains open along strike. In addition, the drilling extended the main orebody further to the east and to the north and still remains open in all directions. Highlights from the current reported holes include:

DRC27:   78.0m @ 0.30 % Cu and 0.20g/t Au (0.44% CuEQ)
DRC29:   39.0m @ 0.28 % Cu and 0.30g/t Au (0.49% CuEQ)
DRC47:   34.0m @ 0.35 % Cu and 0.15g/t Au (0.45% CuEQ)
DRC48:   23.0m @ 0.37 % Cu and 0.25g/t Au (0.55% CuEQ)  AND
DRC48:   11.0m @ 0.62 % Cu and 0.22g/t Au (0.77% CuEQ)
DRC50: 100.0m @ 0.34 % Cu and 0.18g/t Au (0.47% CuEQ)
DRC54:   58.0m @ 0.30 % Cu and 0.15g/t Au (0.41% CuEQ)
DRC71:   57.0m @ 0.37 % Cu and 0.15g/t Au (0.47% CuEQ)
DRC72:   19.0m @ 0.53 % Cu and 0.19g/t Au (0.67% CuEQ)
DRC73:   61.0m @ 0.38 % Cu and 0.20g/t Au (0.52% CuEQ)


Kevin Bullock, Volta Resources' CEO, said, "The latest results at Dienemera clearly illustrate a significant extension of mineralization in this deposit.  Together with the extension of the Gongondy deposit (announced last week), the potential for resource growth on the Gaoua Project has been enhanced.  Volta is currently working with independent consultants to update the NI43-101 compliant resource estimate for the Gaoua Copper-Gold Project."

Volta Resources, with SRK Consulting (UK), is scheduled to complete an updated NI 43-101 compliant resource for the Gaoua Project in early Q1, 2013 incorporating all results from holes drilled to date, including the results reported in this press release.

Significant results for the holes are highlighted in Table 1 and locations shown in Figure 2. Analyses of the Volta Resources samples were undertaken by fire assay on a 50g charge for gold at the Actlabs Laboratories in Ouagadougou, and by Atomic Absorption for copper at the Actlabs Laboratories in Ancaster/Canada. Volta Resources' sampling and assay procedures included rigorous QA/QC elements that employed the inclusion of certified standards and blanks.

Table Notes:

1) Intervals are drilled lengths. True width is unknown at this time.
2) Internal dilution (less than 0.3 % CuEQ) has been carried out to a maximum of 5m except for the intervals in hole DRC44,where the maximum internal dilution (MID) is 6m.
3)  Intersections are based on a 0.3% CuEQ cut-off with no top cut applied.
4)  The intersections listed in the table represent sections of at least 10m@ 0.3% CuEQ.
5)  The intersections represent sections drilled by reverse circulation (RC). The drill holes were sampled at 1m 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.
6)  Samples were sent to Actlabs in Ouagadougou for standard preparation and gold assaying (FA) and to Actlabs in Ancaster/Canada for Cu assaying by atomic absorption spectrometry.
7)  The accuracy of the results was tested through the systematic inclusion of Cu-Au standards and field blanks. Standards were inserted every 15 samples and blanks approximately every 30 samples. The results for the reported holes have passed the Company's QA/QC protocols.
8)  Copper equivalent grade was calculated using US$3.00/lb Cu and US$1400/oz. Au and is not adjusted for mining and metallurgical recoveries as these remain uncertain. The formula used is as follows: CuEQ = Cu% + (Au g/t x 0.7).

On February 5, 2009, the Company announced an independent NI 43-101 compliant inferred resource estimate for the Gongondy and Dienemera deposits on the Gaoua project (See Volta press release dated February 5 2009). The resource estimate was calculated by SRK Consulting (UK) Ltd. At a 0.45% copper equivalent cut-off grade, the Dienemera and Gongondy deposits host an initial Inferred Resource of 82,600,000 tonnes grading 0.40% copper and 0.40 g/t gold for a total of 724,880,000 lbs. of copper and 1,072,900 ounces of gold. The individual resource estimate for each deposit is provided in the table below. Copper Equivalent ("CuEQ") was calculated from assumed revenues of USD 3,000 per tonne of copper and USD 700 per ounce of gold with metallurgical recovery assumed to be 85% and 70% respectively based on initial QEMSCAN results. Gold grade was multiplied by 0.6 and added to the copper grade to provide CuEQ grade. The cut-off grade further assumed typical costs of USD 2 per tonne for mining and USD 10 per tonne for processing and general administration costs.

About Volta Resources:

Volta Resources has a portfolio of quality gold exploration projects in Burkina Faso and Ghana, both mining-friendly West African jurisdictions with proven world-class gold deposits.  VTR will focus on fast-tracking its flagship Kiaka Gold Project (NI-43-101 compliant resources include 117.42 million tonnes @ 1.07 g/t Au for 4,029,000 ounces in the Measured and Indicated categories and 29.96 million tonnes @ 1.00 g/t Au for 1,000,000 ounces in the Inferred category [Please see VTR press release dated March 21, 2012] including 34.38 million tonnes @ 1.04 g/t Au for 1,145,969 ounces of gold in the Proven category and 91.70 million tonnes @ 0.93 g/t Au for 2,742,353 ounces of gold in the Probable category (Please see VTR press release dated May 3, 2012) towards a development decision, aiming to complete a Feasibility Study in Q3, 2013. Recent acquisition of properties around the Kiaka Gold Project has provided VTR with an extensive ground position along the highly prospective Markoye Fault Corridor in an important emerging gold province.
