           Positive Assay Results from Husab Uranium Project, Namibia


Kalahari Minerals Plc, the AIM listed mining exploration and evaluation group
with a portfolio of copper and uranium prospects in Namibia, has received
positive assay results from the first four diamond-drill holes completed at its
49% owned Husab uranium project in Namibia. The results reinforce earlier drill
and spectrometer survey data that the area has significant uranium potential.


Assay highlights include:

   •  4.5m @ 1.246 kg/t U3O8, including 0.5m @ 9.597 kg/t
   •  2.0m @ 1.019 kg/t U3O8
   •  10.0m @ 0.335 kg/t U3O8
   •  10.25m @ 0.264 kg/t U3O8


Kalahari Minerals CEO Peter McIntyre said: 'The Board's confidence in the Husab
uranium project is increasing as the on-going drill programme continues to
produce positive results. These results indicate that the geology is similar to
the other major uranium deposits in the region and we expect to see further
positive indicators as the two-rig 8,000 meter drill programme continues.'


The results are taken from a drilling programme being conducted on the Company's
49% owned Husab Project (EPL3138), a joint venture with Extract Resources
Namibia (Pty) Ltd, situated in a known uranium province strategically located
between the Rossing granite (alaskite) hosted uranium mine (Rio Tinto 68.6%),
and the palaeochannel-hosted Langer Heinrich deposit, currently being developed
by Paladin Resources Ltd. The uranium bearing granite dykes of the Ida Dome were
first explored by a subsidiary of Anglo American Corporation of South Africa in
the late 1970's, however limited exploration has been completed in the
intervening period.


The initial section drilled of the Ida Dome alaskite at the Husab Project,
covered 160 metres of strike extent of a continuous granitic body up to four
kilometres long. The results represent the first drilling on the Ida Central
section of the anomaly and are encouraging from only a limited number of holes.
The uranium grades are generally typical of this class of deposit, represented
by the nearby Rossing, Valencia and Goanikontes deposits, while a narrow higher
grade zone which intersected 0.5m @ 9,597 ppm U3O8 was somewhat unexpected.


Drilling on the Ida target commenced early April 2006 and at the end of June
2006, 2,348m of the total 8,000m first phase drilling programme had been
completed in eight holes. Two drill rigs are currently working at the site and
geological logging and spectrometer sampling of drill core indicates that
uranium mineralisation continues to be intersected.


The information in this announcement as it related to geology, geochemistry and
geophysics, has been prepared and reviewed by Mr. M Spivey who is a competent
person as described in Appendix 5A to the ASX Listing Rules and Part two of the
AIM Guidance Notes for Mining, Oil and Gas Companies.

Notes


Further Details


The Ida Dome alaskitic granite remains only one target within a number of known
uraniferous leucogranites within the Husab joint venture. Drilling on the Ida
Central Zone is continuing with two rigs presently on site, and geological
logging and spectrometer sampling of drill core indicates that uranium
mineralisation continues to be intersected. At the end of June approximately
2,348 metres of NQ drilling had been completed in eight holes.


The uranium mineralisation occurs as primary uraninite together with minor
secondary uranium minerals (predominantly beta-uranophane) in shallow, partially
oxidised, or unusually high grade zones, within, and on the contacts of
alaskitic granite dykes intruding the sheared contact zone between Rossing
Formation marbles, and underlying Nossib Group amphibole-pyroxene schists. The
uranium grades intersected to date are typical of this class of deposit,
represented by the Rossing, Valencia and Goanikontes occurrences. The highest
assay returned to date is 0.5 metres @ 0.959% U3O8 which is unusual for this
setting, and clearly warrants more detailed follow-up.


A feature of the drilling to date at Ida is the potential for hanging wall
alaskite dykes, either intruding the marble, or intruding the upper marble
contact, to carry uranium values. Intersections recorded from hanging wall zones
to date include 10.25 metres @ 0.264 kg/t U3O8 in hole HDD004, and 10 metres @
0.335 kg/t U3O8 in hole HDD002.


Several holes also intersected extensive zones of low grade copper
mineralisation in the footwall of the main alaskite body, including
intersections of 24.5 metres @ 0.184% Cu in HDD011, 6 metres @ 0.335% Cu in
HDD003, and 2.25 metres @ 0.531% Cu in HDD002. The copper mineralisation takes
the form of blebby chalcopyrite accompanying pyrrhotite in the footwall schists
immediately beneath the main alaskite, and represents the copper mineralised
horizon previously exploited in the oxide zone of the historic Ida Copper Mine.
The maximum individual copper value recorded was 2.97% Cu over 0.25 metres in
hole HDD011, which was accompanied by 3.05 ppm Ag and 73 ppb Au.


Uranium intersections greater than 0.1 kg/t U3O8 (100 ppm) from the holes
assayed to date, are listed in Table 1:

   •  Analyses on half cut NQ (50mm dia) core by Genalysis Laboratory Services,
      Perth.
   •  Uranium assays were carried out by a combination of Aqua Regia Digest/MS
      (Method B/MS), and Four Acid Digest/MS (Method A/MS). The majority of 
      assays over 100 ppm were assayed by Method A/MS.
   •  Metal values (U) have been converted to oxide values (U3O8) using a
      factor of 1.179, and expressed as kg/t U3O8. Note that 100 ppm U3O8 is
      equivalent to 0.1 kg/t U3O8.
   •  *Only the top of Hole HDD004 is currently available, with additional
      results to follow.
   •  True widths are estimated to range from 80% to 100% of down hole
      thicknesses.
