TORONTO, June 29, 2011 -


- Measured and Indicated Resources Increase 118% to
3,018,000 ounces of gold AND Inferred Resources Increase 163% to
1,260,000 ounces of gold

Volta Resources Inc. (”Volta” or the “Company”) (TSX: VTR)
announces that an updated NI 43-101 compliant Mineral Resource
estimate has been completed for the Kiaka Gold Project which is
located 140 kilometers south-east of Ouagadougou in Burkina
Faso.  The updated Mineral Resource estimate was prepared by
SRK Consulting UK Limited (Cardiff) (”SRK”) in collaboration with
Volta’s personnel.

The new and updated resource estimate for the Kiaka deposit is
summarized in Table 1 below:

“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
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.
