Volta Receives New Positive Geophysical Results for the South Area at the Kiaka Gold Project

Drilling Will Now Target Similarities to Growing Central Area

TORONTO, May 4, 2010 - Volta Resources Inc. ("Volta" or the "Company") (TSX: VTR) has modified
its drill program for the SOUTH AREA of the Kiaka Main Zone ("KMZ") at its
Kiaka Gold Project, located approximately 120 kilometres southeast of
Ouagadougou, the capital city of Burkina Faso. Volta's ongoing drilling
program for the CENTRAL AREA at Kiaka, the subject of the upcoming NI 43-
101 resource calculation, remains unchanged, with Volta's infill drilling
continuing to confirm the wide mineralized intersections previously drilled
by Randgold (see recent press releases).

The modification of the program for the South Area follows the
completion of IP gradient array and ground magnetic geophysical surveys and
4 new drill holes in the area. Interpretation of the additional data
strongly suggests that the mineralization in the South Area occurs along
the same northeast trend as seen in the Central Area. This is in contrast
to previous interpretations based on relatively sparse drilling by Randgold
that suggested a northerly trend. Consequently, two extended sections will
be drilled across the interpreted position where the KMZ is thought to be
widening in the South Area, instead of the infill drilling planned
previously (see figure 1).

Kevin Bullock, Volta's CEO, said, "We are excited that these
geophysical results show structural relationships similar to those already
confirmed by drilling the KMZ in the Central Area. These results define an
excellent target for wide zones of mineralization and offer the potential
of expanding the overall deposit. In addition to delivering the NI43-101
compliant resource estimate scheduled for June 2010 at the Central Area, we
will also be testing this new potential in the south area."

A composite geophysical image clearly highlights that most of the
mineralization identified so far at the Kiaka deposit is contained between
two, well-defined, NE trending "tram track" structures. Furthermore, the
wide zone of mineralization, confirmed by our drilling in the Central Area,
coincides with north trending cross structures and magnetic highs. This
pattern is repeated in the South Area and to the north (see figure 1). The
swing of the mineralization from a NE trend to a N-S trend, suggested by
previous work, is not supported by the latest data or recent field
observations.

The original 150 hole (~22,000m) drill program planned for the current
phase has now been modified in order to drill test the large South Area
target. It will comprise:

     -   Central Area (KMZ) - approximately 110 holes for 17,500m (just under
         15,000m completed)
     -   South Area (KMZ) - approximately 14 holes for 1,500m

The Company is on track to complete the drilling that will be used in
the NI-43-101 compliant resource estimation for the Central Area in May,
providing sufficient time for assays to be returned and the resource
modeling to be completed before the end of June.

statements with respect to the future price of gold and other minerals and
metals, the estimation of mineral reserves and resources, the realization
of mineral reserve estimates, the capital expenditures, costs and timing of
the resources, the realization of mineral reserve estimates, the capital
expenditures, costs and timing of the development of new deposits, success of
exploration activities, permitting time lines, currency exchange rate
fluctuations, requirements for additional capital, government regulation of

risks related to the integration of acquisitions; risks related to joint
venture operations; actual results of current exploration activities;
actual results of current or future reclamation activities; conclusions of
economic evaluations; changes in project parameters as plans continue to be
refined; future prices of gold and other minerals and metals; possible
variations in ore reserves, grade or recovery rates; failure of equipment
or processes to operate as anticipated; accidents, labour disputes and
other risks of the mining industry; and delays in obtaining governmental
approvals or financing or in the completion of development or construction
activities. Although the management and officers of Volta believe that the
expectations reflected in such forward-looking statements are based upon
reasonable assumptions and have attempted to identify important factors
that could cause actual results to differ materially from those contained
