Volta Announces Maiden NI 43-101 Compliant Resource for its Kiaka Gold Project

Indicated Resources of 41.25Mt (at) 1.04 g/t Au for 1,384,000 Ounces of Gold and Inferred Resources of 15.90Mt (at) 0.90 g/t Au for 480,000 Ounces of Gold

TORONTO, June 29, 2010 - Volta Resources Inc. ("Volta" or the "Company") (TSX: VTR) announces
a maiden NI43-101 compliant resource estimate for its Kiaka Gold
Project, located approximately 120 kilometres southeast of
Ouagadougou, the capital city of Burkina Faso. The resource estimation has
been undertaken by independent consultants, SRK Consulting (UK) Ltd. based in
Cardiff, United Kingdom. The resource estimate is based on more than 25,000
metres of drilling including 147 holes drilled by Volta and previous owner
Randgold Resources Limited. The drilling was completed on schedule and the
results have led to a robust maiden resource with demonstrable upside.

The resource estimation is based on the drill results from the central
area at Kiaka and includes the KMZ and parts of the KHZ and KFZ zones. The
volume modeled and included in the resource estimate by SRK extends for just
over 1 kilometre along strike and down to a maximum vertical depth of 230
metres below surface. SRK concurs with Volta's technical team that higher
grade "mineralized bands" ranging between 5 metres and 20 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 200 metres wide (see Figure 1 and Figure 2). SRK has elected to define
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. The table below
provides a summary of the estimate of Indicated Resources and Inferred
Resources at these cut-off grades.

     Notes
     -----
     -   Mineralized Bands based on a cut-off grade of 1.0 Au (g/t) within
         mineralized wireframe
     -   Halo Mineralization based on a grade bracket of 0.6 - 1.0 Au (g/t)
         within mineralized wireframe
     -   Mineral Resources are not mineral reserves and thus do not have
         demonstrated economic viability

Kevin Bullock, Volta's CEO, said, "We are proud to release this maiden
resource estimate that has met our very aggressive timeline, that establishes
an initial total amount of gold ounces at the upper end of our original gold
resource goal, and that demonstrates significant future potential. This
resource estimate amply confirms Kiaka's status as one of West Africa's major
emerging gold projects. We intend to maintain our aggressive pace with
another major drill campaign and a scoping study this year, leading towards a
pre-feasibility program, as part of our commitment to advance Kiaka on the
production path as quickly as possible."

The estimate is based on a combination of diamond core and RC chip
samples which were fire assayed for gold by ALS in Ouagadougou. Field rejects
from the mineralized intersections of the RRL RC drillholes have been
re-sampled and included in Volta's assay database; comprehensive QAQC has
demonstrated that sample preparation and laboratory performance for both
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 and KFZ structures that were wireframed using an approximate 0.3 g/t
shell. A block model was then generated using block dimensions of 20 metres x
20 metres x 5 metres, into which up to 40 x 1 metre composite samples per
block were used for estimation employing an ordinary kriging routine with a
variably oriented search ellipse, following the undulating mineralized bands
identified. The resultant block grade distribution reflects the curvilinear
banding which both Volta and SRK consider to be an important feature of the
deposit.

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 RRL sighter
tests and a long term upside gold price of US$ 1040/oz to determine that the
current resource and its potential depth extensions have sufficiently high
rade, width and proximity to surface to have reasonable prospects for
economic extraction by open pit. Based on the current economic parameters
applied within Whittle, the open-pit bottoms out on the deepest Inferred
Resources, which are currently only defined to the 50 metre RL (or 230 metres
below surface), (see Figure 2). Additional drilling below the current
Inferred Resource limit could add to the resources.

The following Table shows the sensitivity of SRK's block model within
the Whittle open pit, at a range of cut-off grades from 0.0g/t to 1.4g/t.

SRK states that, and Volta concurs, there is considerable potential to
find additional resources in the Central Area at Kiaka. These could be
derived from:

     -   at depth beneath the main mineralized strike interval identified so
         far,
     -   along strike to the south where scout drilling has encountered
         encouraging mineralization,
     -   along strike to the north where faulting may have offset the
         mineralization to the east of the current drilling coverage; and
     -   Within the current mineralized wireframes where more material is
         present at lower-grade which could add low grade ounces to the
         deposit should more favourable costs than currently assumed be
         defined.

In addition, drilling currently underway in the south area
(approximately 400 metres to the south of the current resource) is pursuing a
target that has similar geological and geophysical characteristics to the
central area. Volta plans to continue exploration at Kiaka including more
than 20,000 metres of additional drilling in the second half of this year.
Volta also plans to commence a scoping study this year which will lead into a
pre-feasibility program.

Volta carries out a rigorous QAQC procedure on its sampling and assaying.
The RC portions of the drill holes were sampled at 1-metre intervals. Dry
samples were riffle-split to provide 2 kilogram 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 metre
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.
Certified standards were inserted every 15 samples, field duplicates (in the
RC portions) about every 20 and blanks about every 30 samples.
