Mantra Resources Limited - Quarterly Report To The Australian Securities Exchange For The Period Ending 31 December 2010

PERTH, Western Australia, Jan. 31 /CNW/ - Mantra Resources Limited ('Mantra' or 'Company') (ASX: MRU, TSX: MRL) is pleased to present its quarterly report for the period ended 31 December 2010. The Company's primary operational focus during the period continued to be the advancement of the Phase 1 Definitive Feasibility Study ('DFS') at the Nyota Prospect ('Nyota' or 'the Prospect'), part of the Mkuju River Project ('MRP' or 'the Project') in southern Tanzania. The quarter's highlights include:


ARMZ ALL-CASH OFFER

* Receipt of an all-cash offer ('Offer') from ARMZ Uranium Holding Co. (JSC Atomredmetzoloto) ('ARMZ') to acquire all of the issued shares in Mantra for A$8.00 per share (the 'Offer Price') via a Board recommended scheme of arrangement (the 'Scheme') under the Australian Corporations Act. The Offer values Mantra at approximately A$1.16 billion.

The Offer Price represents a 15.5% premium to the 20 day VWAP and a 21.2% premium to the 30 day VWAP on the ASX. The Offer also values Mantra at US$10.26 per pound of resource, which is significantly higher than other substantial uranium developers.

The Offer enables Mantra shareholders to realise immediate value for their Mantra shares and reflects the size, strategic nature and near-term development potential of the MRP uranium deposit.

* A Scheme Booklet and Independent Expert's Report in relation to the Offer are currently being prepared. Both documents will be filed with the ASIC for review on approximately 11 February 2011, and will be dispatched to shareholders in approximately mid-March after all necessary approvals have been obtained.


OPERATIONS AND EXPLORATION ACTIVITIES

* A substantial increase in the Nyota Mineral Resource Estimate ('MRE') was announced on 16 November 2010:
o The MRE has increased by 20% from the previous statement (84.3 Mlbs);
o Total Measured and Indicated Resources increased by 130% to 65.5 Mlbs U3O8 or 65% of the MRE;
o A 200 ppm U3O8 lower cut-off grade has been maintained and the average grade of the Measured and Indicated Resources is 439 ppm U3O8;
o Majority of the MRE is within 60 metres of surface;
o Aggressive and successful drilling has led to rapid growth in the MRE; and
o Upgraded MRE to be fully integrated into the Phase 1 DFS.

All figures are rounded to reflect appropriate levels of confidence. Apparent differences may occur due to rounding

* Completion of the final, optimised process flowsheet for the MRP DFS. The final outcome is a highly simplified, single stream metallurgical flowsheet that maximises uranium recovery. This modified flowsheet has increased overall uranium recovery to 82% from the Phase 1 Pre-Feasibility Study ('PFS') figure of 79%.

* The PFS on heap leaching lower grade mined ore at the MRP for the Project's second phase of growth commenced in the period. The Heap Leach PFS includes further resource modelling and detailed leaching testwork to allow grade/recovery relationships to be investigated and the minimum cut-off grade for economic treatment of the Nyota deposit to be determined.

* Completion of the 2010 exploration drilling program. The program comprised a total of approximately 39,550m of aircore/open-hole drilling and 1,050m of diamond drilling. Mineralisation was intersected adjacent to current resource areas, particularly in the central-eastern portion of the Prospect area, with significant intersections including 11m @ 1,824 ppm eU3O8, 14m @ 1,225 ppm eU3O8, 19m @ 786 ppm eU3O8, 17m @ 836 ppm eU3O8and 8m @ 1,757 ppm eU3O8.

* Completion of initial phases of aircore drilling on the Satellite Targets within the MRP (but outside the Nyota Prospect) and at the Mbamba Bay Project. Assays results are pending.

* Completion of a follow-up RC drilling program at the Zambezi Valley Project in Mozambique. Shallow mineralisation was recorded in a number of holes, including a peak intersection of 12m @ 1,059 ppm U3O8 from 45m depth.
