Higher Grade Lenses Support Phased Development and Selective Mining Approach at Volta Resources' Kiaka Gold Project

- Feasibility Study to be based on phased development / selective mining approach
- Global Measured & Indicated resources increase by 10% to 4,862,000 ounces gold

TORONTO, Jan. 10, 2013 /CNW/ - Volta Resources Inc. ("Volta Resources" or the "Company") (TSX: VTR) announces an updated NI 43-101 compliant Mineral Resource estimate for the Kiaka Gold Project, located approximately 140km southeast of Ouagadougou in southern Burkina Faso. The updated Mineral Resource estimate has been undertaken by independent SRK Consulting (UK) Limited from Cardiff, with input from Volta's geological team. The update follows completion of an additional 233 holes (38,602m) drilled in Phase 4 at the Kiaka Central Area. Including the Randgold drilling (18 holes) and Volta's drilling phases 1 to 3, the total amount of drilling used for the resource estimates at the Kiaka Central and Kiaka South resource areas now stands at 1,623 holes (237,971m).


Highlights:

- Confirmation of the continuity of higher grade lenses within the Kiaka Main Zone (KMZ), facilitating the definition of discrete lenses (KMZ_Lenses) hosting Measured and Indicated Resources of 41.68 Mt @ 1.52 g/t Au for 2,039,000 ounces of gold and Inferred Resources of 5.51 Mt @ 1.70 g/t Au for 301,000 ounces of gold.

- Surrounding the KMZ_Lenses, the KMZ_Halo hosts additional Measured and Indicated Resources of 83.75 Mt @ 0.77g/t Au for 2,072,000 ounces of gold and Inferred Resources of 9.87 Mt @ 0.73 g/t Au for 231,000 ounces of gold.

- Adjacent to the KMZ_Lenses and KMZ_Halo, the Kiaka Footwall Zone (KFZ), the Kiaka Hangingwall Zone (KHZ) and the Kiaka Upper Block (KUB) (collectively referred to as the Adjacent Zones) add a further 26.00 Mt @ 0.76 g/t Au for 633,000 ounces of gold in the Measured and Indicated categories and 18.28 Mt @ 0.80 g/t Au for 469,000 ounces of gold in the Inferred category.

- The total Kiaka Project, including Kiaka Central and Kiaka South, now contains Measured and Indicated Resources of 153.26 Mt @ 0.99 g/t Au for 4,862,000 ounces of gold and Inferred Resources of 33.74 Mt @ 0.93g/t for 1,006,000 ounces of gold (unchanged). This represents a 10% increase in Measured and Indicated Resources, when comparing both sets of models at a 0.4g/t cut-off.

- The total Kiaka Project has higher grade Measured and Indicated Resources of 29.56 Mt @ 1.51g/t for 1,437,000 ounces of gold occurring within the top 250m of the deposits, sufficient to sustain processing ore at an in situ grade approximately 40% higher than the average grade of the deposits in a 6.0 Mt per annum facility for up to five years.


Kevin Bullock, Volta's President and CEO, commented, "The primary objective of the work leading to this latest Mineral Resource update for the Kiaka Gold Project has been met. We can now confidently define discrete and continuous higher grade KMZ_Lenses within the broader lower grade KMZ envelope in the Kiaka Central Area. This supports and clearly illustrates that it would be practical to selectively mine and process sufficient tonnes of ore at an in situ grade approximately 40% higher than the average grade of the deposit for up to five years, while stockpiling the lower grade ore, thereby supporting a phased development approach for the Kiaka Project. This would entail installing initial processing capacity of 6.0 Mt per annum (significantly lowering CAPEX) for up to five years and scaling up to 12.0 Mt per annum for the remainder of the mine life. The phased development scheme will now be implemented in the current Feasibility Study being carried out for the project."

Mr. Bullock also noted, "We are delighted that the Mineral Resource on the Kiaka project has once again increased. Significantly, the Measured and Indicated Resources now stand at 4.86 Moz of gold, representing a 10% increase, while the Inferred Resources remain unchanged at 1.0 Moz of gold. The Kiaka Gold Project now hosts the largest undeveloped gold deposit in Burkina Faso and one of the largest undeveloped gold deposits in the West African region."

Notes:

1. Mineral Resources have been prepared under the CIM guidelines for reporting of Mineral Resources and Mineral Reserves.
2. This Mineral Resource estimate is based on a cut-off grade of 0.4 Au (g/t) within mineralized wireframes, within a conceptual Whittle pit shell based on a gold price of US$1,400 per ounce, marginal operating costs of US$11.89 per tonne for processing and G&A and US$1.58 per tonne for mining (assuming a 12Mtpa CIP operation - as per Pre-feasibility study) and assuming a process recovery of 89.8%.
3. In the Kiaka Central Area "KMZ_Lenses" and "KMZ_Halo" represent the high and low grade domains within the KMZ respectively, whilst the "Adjacent Zones" represents KHZ, KFZ and KUB (Kiaka Upper Block) mineralization.
4. The Kiaka South Area deposit included in the overall Kiaka Project resource estimate is located less than 700m south of the Kiaka Central Area and the Mineral Resource estimate, restated here, was undertaken and reported in September 2012.
5. SRK used a block model with block dimensions of 5 x 20 x 10m into which gold grades have been estimated based on optimised ordinary kriging routines with a search ellipse orientated to follow the strike of each domain.
6. Mineral Resources have been classified such that Measured Resources have been defined to areas of infill drilling of better than 25m x 25m, Indicated Resources to 50m x 50m and Inferred Resources to blocks lying outside of Indicated wireframes which still display reasonable strike continuity and dip extension.
7. All figures are rounded to reflect the relative accuracy of the estimate. All composites have been capped where appropriate.
8. Mineral Resources are not Mineral Reserves and do not necessarily demonstrate economic viability.  
9. The RC and cored samples were collected at 1m intervals. Dry RC 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 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 sent to the laboratory.
10. Samples associated with this Mineral Resource update were assayed at the ALS Chemex laboratory in Ouagadougou, Burkina Faso. The ALS Minerals quality system complies with the requirements of the international standards ISO 9001:2000 and ISO 17025:2005 and operates in all their laboratory sites.  Samples were assayed for gold (fire assay with AAS finish), using the ALS protocol with laboratory code "Au_AA26".
11. Volta's QAQC procedures include the insertion of certified standards every 15 samples, field duplicates (in the RC portions) about every 25 and blanks about every 10 samples.  SRK has analysed the data generated by the QAQC procedures  and deems the data to be acceptable for use in the estimation of Mineral Resource Estimates, to be reported in compliance with CIM "Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines" (CIM Standards). 

.

The KMZ comprises a 100m to 260m wide orebody, extending for over 1,500m along strike and over 500m down dip. The KMZ is readily defined within a 0.3 g/t Au mineralized envelope, corresponding to deformed, altered and north-easterly trending corridor of Birimian meta-sedimentary and meta-volcanic lithologies.

Although it was recognized early on by Volta and SRK that there were higher grade lenses of mineralization within a broad halo of lower grade mineralization within the KMZ, previous resource estimates were based on grade interpolation within the overall broad mineralized envelope. In order to highlight the potential of the higher grade zones, previous resource estimates presented a global breakdown of the KMZ mineral resource as "Mineralized Bands" (>1.0 g/t Au) and "Halo Mineralization" (between 0.6 g/t Au and 1.0 g/t Au).

Additional infill drilling, re-logging , interpretation and modelling of the drilling undertaken since the last Mineral Resource estimate in the Kiaka Central Area has now successfully confirmed the presence of discrete higher grade lenses (KMZ_Lenses) ranging between 5m and 50m wide. These extend with good continuity for 100m to 800m along strike and 50m to 400m down dip. They are surrounded by lower grade mineralization (KMZ_Halo), within the broad KMZ orebody.

The confidence in the current interpretation and model for discrete and continuous KMZ_Lenses surrounded by KMZ_Halo is supported by:

- The KMZ_Lenses are visually recognized in drill core as being associated with a retrograde metamorphic event (appearance of a secondary biotite and garnet replacement by chlorite) associated with more intense deformation, overprinting the prograde metamorphic signature that characterises the KMZ_Halo mineralization.

- The KMZ_Lenses can be traced from hole to hole and section to section so that SRK were able to delineate hard boundaries to constrain them for modelling. This has resulted in a marked improvement in geostatistical domaining, thereby significantly reducing the nugget effect, increasing range in the variograms and overall confidence in the resource estimate.


The nature, scale and continuity of the KMZ_Lenses are such that they would be amenable to selective mining for priority processing, while the KMZ_Halo would be stockpiled for processing later. Overall, there are 29.56 Mt @ 1.51g/t Au for 1,437,000 ounces of gold of higher grade material occurring within the top 250m of the deposits.  This could be sufficient to sustain processing ore at an in situ grade approximately 40% higher than the average grade of the deposits utilizing a 6 Mt per annum facility for 5 years.

This is illustrated in the graph below, where block model Measured and Indicated Resource tonnage and grade estimates within the conceptual Kiaka Central and Kiaka South resource pits are shown in 50m incremental elevations below surface for the Kiaka Project.

The previous Mineral Resource, reported on 20^th March 2012, for Kiaka Central was based on a 0.6g/t cut-off grade. The Kiaka Prefeasibility Study completed in 2012 utilized a 0.4g/t cut-off grade to define Mineral Reserves for Kiaka Central. Consequently, the current Mineral Resource estimate utilizes a 0.4g/t cut-off grade for Kiaka Central. The previous Mineral Resource for Kiaka South used a 0.4g/t cut-off, so this is unchanged. Therefore, comparing like with like at Kiaka Central, there has been an increase in tonnage (+13%), a decrease in grade (-3%) and an overall increase in ounces (+10%) in the Measured and Indicated Resources at the 0.4g/t cut-off grade.

Table 2 shows the Measured and Indicated and Inferred Resources at incremental cut-off grades from 0.2 g/t Au to 1.4 g/t Au, within the updated geological block model for the Kiaka Central Area.

The main focus for the Kiaka Project is now to complete the final Feasibility Study before the end of Q3 2013. The study will be based on a phased development scenario, whereby significantly higher grade ore will be selectively processed (with lower grade ore stockpiled) in a 6.0 Mt per annum plant for five years, scaling up to process 12.0 Mt per annum for the remainder of the Life of Mine. This will considerably reduce initial CAPEX and reduce payback periods.

Additional metallurgical test work including more comminution studies and variability analyses is currently underway. Geotechnical and hydrological studies are well advanced with drilling dedicated to these aspects almost complete. Waste rock characterization studies, including test work for acid rock drainage and metal leaching (ARDML), are underway. Civil geotechnical studies to assess load bearing characteristics for heavy infrastructure and substrate conditions for tailings and rock waste storage sites is almost complete. Baseline studies and an Environmental and Social Impact Assessment undertaken to meet IFC Performance Standards are also close to completion.

Exploration on the Kiaka permit will now focus on testing some of the other regional targets identified by Randgold and Volta in this highly prospective area.

A copy of the full technical report that accompanies the NI 43-101 resource statement will shortly be posted on the Volta Resources website and on SEDAR.
