'Our drilling programs have more than doubled the mineral resource base
from last year's estimate at Kiaka while also significantly increasing
the confidence of the geological model' stated Kevin Bullock, Volta's
President & CEO.

He went on to say 'The Volta team has once again delivered the estimate
on time and on budget and I commend them on their efforts.  The extent
of the current resource upgrade elevates the Kiaka deposit to the next
category in terms of quality and size. Notwithstanding the success of
the Phase 2 campaign, the Kiaka deposit is not closed off yet, with
further potential indicated along strike and down dip. There are also
untested targets in close proximity that will be drilled in Phase 3. 
Combined with its favorable location and positive results from initial
metallurgical test work, the prospects for the Kiaka deposit have been
considerably enhanced.'

This mineral resource estimate is based on approximately 72,500 m of
diamond and RC drilling: 35 drill holes for 8,083m from Randgold, the
previous owners, and 365 drill holes for 64,484 m from Volta's ongoing
drilling campaign. In comparison to 2010, an additional 245 drill holes
have been incorporated, representing an additional 45,409 m of drilling
and 45,862 new assays, representing a 69% increase in the size of the
assay database.

Phase 2 drilling has now extended the Kiaka deposit to >1.5km along
strike (illustrated in plan and longitudinal section in Figures 1 and
2) and down to an average depth of approximately 450m below surface
(illustrated in cross sections in Figures 3 and 4).  The additional
drilling has confirmed that higher grade 'mineralized bands' ranging
between 5 metres and 50 metres wide extend with good continuity for 100
metres to 400 metres along strike and 50 metres to 200 metres down dip.
These 'mineralized bands' are hosted within a lower grade 'halo
mineralization' within a structural corridor that is 100 metres to 250
metres wide. SRK has elected to report resources from the 'mineralized
bands' at a cut-off grade of 1.0 g/t gold and the 'halo mineralization'
at a cut-off grade of 0.6 g/t gold.

Infill drilling has resulted in considerably increasing the confidence
in the geological model, leading to 1,031,000 ounces now reporting to
Measured Resources.  Measured and Indicated Resources have increased by
118% from 1,384,000 ounces to 3,018,000 ounces and Inferred Resources
by 163% from 480,000 ounces to 1,260,000 ounces. The change in the
Mineral Resources from June 2010 to June 2011 is highlighted in Table
2.

 The estimate is based on a combination of diamond core and RC chip
samples which were fire assayed for gold by ALS, SGS and BIGS
laboratories in Ouagadougou. Field rejects from the mineralized
intersections of the Randgold drill holes have been re-sampled and
included in Volta's assay database; comprehensive QAQC has demonstrated
that sample preparation and laboratory performance for all drilling
campaigns provided assays which are fit for the purpose of this
estimate. 

The grade estimation domains comprise the wide KMZ corridor and flanking
KHZ structures that were wire-framed using an approximate 0.3 g/t
shell. A block model was then generated using block dimensions of 20
metres x 10 metres x 5 metres, into which up to 24 x 3 meter composite
samples per block were used for estimation employing an ordinary
kriging routine.

SRK has considered sampling density and distance from samples in order
to classify the Mineral Resource according to the terminology,
definitions and guidelines given in the Canadian Institute of Mining,
Metallurgy and Petroleum (CIM) Standards on Mineral Resources and
Mineral Reserves (December 2005) as required by National Instrument
43-101. Further, SRK has used reasonable costs for the region, process
recoveries based on the results of an internal scoping study (currently
being completed by SRK) and a long term upside gold price of US$
1,175/oz to determine that the current resource and its potential depth
extensions have sufficiently high grade, width and proximity to surface
to have reasonable prospects for economic extraction by producing a
Whittle open pit shell.

 Volta will continue with the Phase 3 (50,000 meter) drilling program to
further extend and enhance the Kiaka deposit, test other local targets
already identified within a 3 kilometer radius of the currently defined
deposit and to carry out scout drilling on the other regional targets
on the 184 km(2) Kiaka property.

Volta plans to enter into a pre-feasibility study over the second half
of the year that will concentrate on optimizing metallurgical test work
and mining schedules.  This will be done in tandem with generating
appropriate and project specific operating and capital cost parameters
for the Kiaka deposit.  This is consistent with Volta's stated
objective of fast-tracking the development of the Kiaka deposit to
generate the best return for shareholders.

A copy of the full technical report that accompanies the NI 43-101
resource statement will be posted on Volta's website and on SEDAR
within 45 days.
