Mantra Resources Limited - Positive results from Resin-in-Pulp metallurgical
testwork on Nyota Prospect

PERTH , Western Australia , Nov. 30 /CNW/ - Mantra Resources Limited ('Mantra' or 'Company') (ASX: MRU, TSX: MRL) is pleased to announce positive results from the recently completed Resin-in-Pulp ('RIP') metallurgical testwork. The Australian Nuclear Science and Technology Organisation ('ANSTO') completed the testwork using over one tonne of mineralised material from the Nyota Prospect ('Nyota' or 'Prospect'), part of the Company's wholly owned Mkuju River Project ('MRP' or 'Project') in southern Tanzania .

Mantra completed a Scoping Study on the Nyota Prospect in June 2009 utilising a counter current decantation ('CCD') process route. The Scoping Study revealed that the process route could be further enhanced by the use of RIP. ANSTO completed batch and pilot scale testwork and the results were used in an engineering and metallurgical trade off study between RIP and CCD. The testwork and trade off study has clearly demonstrated that the RIP process is the preferred process route for the MRP. The advantages of this process route are summarised as follows:

    
    -  Simplification of operation with the removal of the CCD circuit;

    -  A significant reduction in size or elimination of the solvent
       extraction ('SX') plant with the potential to go to direct
       precipitation;

    -  Reduction in overall reagent use;

    -  Smaller plant footprint; and

    -  Greater flexibility in the processing of mineralisation in varying
       host rock types.
    

The RIP process is currently being used by Paladin Energy Limited at their Kayelekera Project in Malawi and has been used in uranium recovery in the United States and former Soviet Union for many years.

The Company is well advanced in its Pre Feasibility Study ('PFS') on Nyota and will be utilising the RIP flowsheet in the capital and operating cost estimates for the Project.

A full report complete with details of this recently completed testwork, including supporting graphics and a conceptual process flow sheet, is available on the Company's website (www.mantraresources.com.au), ASX (www.asx.com.au), and SEDAR (www.sedar.com).
