Kalahari Minerals plc / Ticker: KAH / Index: AIM / Sector: Mining & Exploration 12 March 2010 Kalahari Minerals plc (Kalahari) Update on R�ssing South Feasibility Study
Kalahari Minerals plc, the AIM listed resource company with uranium, gold and base metal interests in Namibia, is pleased to provide an update, published by Extract Resources Ltd (Extract or the Company), in which Kalaharis subsidiary, Kalahari Uranium Limited, holds a 40.41% interest, regarding an update on the progress made on the R�ssing South Definitive Feasibility Study, which is expected to confirm the projects potential to be one of the worlds largest uranium mines.
Kalahari Executive Chairman Mark Hohnen said, "We are highly encouraged by this news, which confirms that Extract is making strong progress towards publishing the R�ssing South Definitive Feasibility Study, and in turn, attributing additional value to its world-class Husab Uranium Project.

In particular, it should be noted that the operating costs are unlikely to be significantly different to those stated in the scoping study announced in August 2009, indicating that the R�ssing South project is still set to be a profitable, low risk, bulk tonnage, open pit mine with a mine life in excess of 20 years.
"Kalahari remains fully supportive of the development work conducted by Extract, and we now eagerly await an upgraded resource from Zones 1 and 2 of R�ssing South.

We believe this will not only considerably increase the overall size of Extracts uranium resource, but will also reiterate the global significance of this mineralised system.

Indeed, the delay in the definitive feasibility study is attributable to the fact that the resource continues to grow in size, which increases the time required by Extract to better define the ore body, and in particular to identify the high grade resource.

This approach by Extract will ensure that an optimum development plan can be determined in order to maximise the true potential of this outstanding uranium project."
Extract Announcement:
R�ssing South: Project Feasibility Study Update
Australia - March 12, 2010 - Australian-based uranium mine development and exploration company, Extract Resources Limited (ASX/TSX: EXT) ("Extract" or "the Company") reports that the R�ssing South Definitive Feasibility Study ("DFS") continues to progress well and is on track to confirm the projects potential to be one of the worlds largest uranium mines.

The base case mine plan remains low risk, bulk tonnage, open pit mining, with ore processed through a conventional agitated tank leach plant.


The size of the R�ssing South mineralized system continues to grow with strong drilling results continuing from Zones 1 and 2.

There are encouraging indications of significant mineralization on the western limb of the R�ssing South antiform and high grade mineralisation in both zones.


Extract aims to announce an updated R�ssing South resource in Q3, 2010.

This revised resource estimate will incorporate infill and extensional drilling that has been completed since July 2009.

The updated estimate is expected to increase the overall size and confidence levels of the R�ssing South resource.


As part of the ongoing process of optimising the currently defined resource, the most recent mine plan incorporates an average stripping ratio of 6.9:1 over the life of mine.

Open pit mining studies indicate that approximately 120 Mt of pre-strip material is to be removed to enable ore movement rates of approximately 15 Mtpa to feed the processing plant.


As outlined in the Preliminary Cost Estimates ("PCE") released on 3 August 2009, several items were excluded from the initial capital costs estimate.

Extract is continuing to refine the cost of independently developing R�ssing South, including the costs of using either an owner-operator mine fleet or contract mining.

Studies to fully define the costs associated with procurement of water, power and acid delivery, together with external infrastructure including rail and road, are ongoing.


Extract, together with its technical consultants, continues to undertake value engineering to optimize the development of the project and will provide an update following completion of the DFS, completion of which is currently commencing operation in Perth.

Extract expects this work to confirm overall process plant recovery as well as reagent and acid consumption.


Extract notes that capital costs for the processing plant and annual operating costs are currently expected to remain in line with the PCE.

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 Tintos 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 Kalaharis estimates of a resource in the region of 500 M lbs U3O8.
Kalaharis 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.
