Perth, Australia, Jan 31, 2012 - (ABN Newswire) - South Boulder Mines Limited (ASX:STB.AX - News) is pleased to provide a quarterly report for the period ended 31 December 2011.


A detailed engineering scoping study (ESS) for the Colluli Potash Deposit was completed generating highly favourable technical and financial results;

--------------------------------------------- Pre-production capital (Including 15% contingency) USD 0.74 bn --------------------------------------------- Pre-tax NPV12% (12% Discount rate) USD 1.33 bn --------------------------------------------- Internal rate of return(IRR) 40.60% --------------------------------------------- Project revenue USD 6.03 bn --------------------------------------------- MOP production rate 1Mt p.a. --------------------------------------------- Mining method Open pit --------------------------------------------- Study mine life 17 years --------------------------------------------- Current resource utilisation ~ 16% ---------------------------------------------

The results firmly confirm Colluli as a "Tier 1" global potash asset with enormous upside potential and a definitive feasibility study (DFS) is well underway for completion in 2013;

Assays and resource extension drilling continue to define shallow potash outside the existing resource including new hole Col-049 (not previously released) which intersected a total thickness 16.35m of potash from 91.22m including 9.51m of Sylvinite. An updated JORC Compliant Mineral Resource Estimate is planned for the March quarter;

Highly experienced finance and corporate executive Flavio Garofalo joins South Boulder as Chief Financial Officer to expedite The Company transition to potash producer;

An initial JORC Compliant Mineral Resource Estimate has been compiled for the Rosie Ni-Cu- PGE sulphide deposit comprising 1,744,000t @ 1.7% Ni (29,800 Ni t), 0.4% Cu and 1.9g/t Pt +Pd (>1.0% Ni cut-off). A further phase of exploration drilling at the Duketon Nickel JV is scheduled to commence in February. Mineralisation remains open along strike and at depth;

Organisation for a series of strategic investor visits to the Colluli Project throughout the March and June quarters is well advanced to assist assessing potential financial, off-take and development partners;

South Boulder is well funded to progress the Colluli DFS and is in the process of finalising a fully underwritten 1 for 5 Entitlement Issue to raise ~ A$10.7m. This will result in a strong cash position of ~A$21 million in early February 2012, an additional A$2.5 million in equities with a further A$4.2 million expected from option conversions.
