Further Exceptional Results from Rössing South

Kalahari Minerals plc, the AIM listed resource company, is pleased to provide
an update, published by Extract Resources Ltd (`Extract' or `the Company'), in
which Kalahari's subsidiary, Kalahari Uranium Limited, holds a 40.41% interest,
regarding further exceptional chemical assay results from the Rössing South
mineralised system, part of Extract's world-class Husab Uranium Project.

Kalahari Executive Chairman Mark Hohnen said, "These are again truly fantastic
results. Both Zones 1 and 2 of Rössing South continue to deliver exceptionally
wide uranium intercepts in excess of 1,000ppm, with highlights of 22m @
1,410ppm from Zone 1, and 41m @ 1,222ppm from Zone 2, further confirming the
global significance of the Husab Uranium Project. Importantly, the results
continue to support the view that these zones are continuous at depth, and
open, which should be significant with respect to the resource update scheduled
for Q3 2010.

"Significantly, the resumption of exploration drilling has met with immediate
success on the Western Limb of the Rössing South anticline, which is believed
to have the potential for yet more zones of mineralisation, further increasing
the scale of the project area. The proximity of the Western Limb to the
existing zones 1, 2 and 3 should allow for any resources and reserves defined
at these new prospects to be included in any future mine development.

"The initiation of design of the pilot plant testwork programme marks an
important step towards completion of the definitive feasibility study scheduled
for later this year, where preliminary cost estimates have already indicated
Rössing South can support production of at least 14.8Mlbs U3O8 per year. With
17 rigs currently operating and more rigs due to join the programme soon, we
believe Rössing South is one of the largest drilling programmes currently being
undertaken anywhere in Africa and is testimony to the magnitude and importance
of the Husab Uranium Project as a whole."

Resource Definition Update - Zone 1 & Zone 2

The Company continues to increase the number of drilling rigs on site with a
total of 17 now operating at Rössing South. Four reverse circulation (RC) rigs
and seven diamond core rigs are completing infill and resource extensional
drilling at Rössing South and an additional RC rig is continuing with
sterilization drilling. The other five rigs have been deployed to exploration
drilling.

At the Rössing South project the company has now completed over 300,000 metres
of drilling with 232,347 metres of this total dedicated to resource definition
within Zone 1 and Zone 2 (Figure 1). The Company anticipates that the infill
and resource extensional drilling completed since July 2009 will move more of
the resource to the Indicated category and will be incorporated in the
Definitive Feasibility Study. An updated resource statement for Zone 1 and Zone
2 is expected to be announced in Q3, 2010.

The latest round of chemical assay results were received from 66 drill holes
located throughout Zone 1 and Zone 2. Multiple intercepts of high grade
mineralization were reported reconfirming the continuity of the high-grade,
granite-hosted uranium mineralization. Highlights are shown in Figure 1 (below)
and a full list of recently received and previously unreported chemical assay
results is included in Appendix 1.

Uranium mineralisation remains open along strike and down dip at both Zone 1
and 2, with additional drilling expected to increase the size of this globally
significant mineral system. Figure 2 (below) is a plan showing the gridded and
contoured uranium assay x mineralized intersection thickness product in each
hole drilled to date, where chemical assay results are available. It shows
several high value areas have been identified at both zones, some of which are
still open, making these excellent early mining targets. Additional drilling is
expected to increase the size of these high grade domains.

Figures 3 and 4 (below) are cross sections of Zone 1 and Zone 2, respectively.
Each illustrates the geological interpretation and demonstrates the continuity
of the high-grade, granite-hosted uranium mineralisation at Rössing South.
Figure 3 (cross section looking west) shows the high grade area at the southern
end of Zone 1. The southerly plunge of the mineralised system in this part of
the deposit is evident and reinforces the view that additional mineralisation
can be expected in the gap between Zone 1 and Zone 2.

Figure 4 (cross section looking north) illustrates that mineralisation has been
intersected on both the east and west limb of the Rössing South anticline.
Mineralisation has been defined on this section over a width in excess of 1000
metres and is still open down dip on both fold limbs.

Exploration Update

As previously announced (ASX Release 26th October 2009) the Company has
identified the western limb of the Rössing South antiform as a structural
position with potential to host uranium mineralization. Recent drilling of this
target has confirmed this potential with four RC rigs and one diamond core rig
currently dedicated to drilling out this area. Hand held spectrometer results
indicate that high grade uranium mineralisation has been intersected in
multiple drill holes. Chemical assay results are pending and will be announced
in due course.

This western limb area has only been partly tested and additional drilling is
required down-dip to the west and along strike to the north and south to
determine the extent of this high value mineralization. Additional drilling
rigs are being deployed to further test this highly prospective target.

Rössing South Feasibility Study Update

Results of metallurgical testwork done to date have been encouraging. One of
the final steps in this process is completing metallurgical tests in a pilot
plant. Approximately 10 tonnes of drill core has been transported from Namibia
to Perth for `proof of design' pilot plant testwork. Commissioning of the pilot
plant commenced on 22 March 2010 and all test work is expected to be complete
by the end of June 2010. The objectives of this work are to finalise the base
case flow sheet, to quantify comminution, leaching, filtration, ion exchange,
solvent extraction parameters and to characterize uranium product for marketing
purposes. Of particular interest will be acid, water and other reagent
consumption rates.

uranium values are recorded by placing the unit on the bulk RC sample bags or
individual trays of drill core and expressed as parts per million (ppm) eU
which is equivalent to ppm U. Results from these units provide an indication of
uranium mineralisation; they may also be affected by uranium mobility and
disequilibrium. These factors should be considered when interpreting eU
information whilst waiting for confirmation chemical assay results.

Notes to Editors:

Kalahari Minerals plc is an AIM and NSX listed resource company with uranium,
gold and base metal interests in Namibia. Its key investment is its 40.4%
holding in ASX, TSX and NSX listed Extract Resources Limited
(www.extractresources.com), which is developing the Husab Uranium Project,
strategically located directly south of Rio Tinto's producing Rossing Mine.
Work is focussing on three main prospects within the project area, Rossing
South, Ida Dome and Hildenhof, and results continue to underpin the
prospectivity of the region, particularly following the world class Rossing
South discovery. Extract has reported a JORC compliant combined Husab Resource
(Global Resource) in excess of 292 M lbs U3O8 at a grade of 439 ppm of which
267 M lbs U3O8 at a grade of 487 ppm is from the two zones at Rossing South at
100 ppm U3O8 cut-off. Importantly, these are both open ended at depth and along
strike. Kalahari believes Extract has the ground and potential to deliver on
Kalahari's estimates of a resource in the region of 550 M lbs U3O8.

Kalahari's other key investment is its circa 44.9% holding in North River
Resources plc, an AIM listed emerging southern African focussed multi commodity
resource development company.
