Dear all,
Please find below a summary of an announcement made to the ASX and TSX today.


PERTH, Western Australia: 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 Companys 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.
