CURRENTLYThe country gained its independence in 1991;

UN supervised referendum made it official in 1993;

Population ~ 5.0 million people; 80% dependent
on subsistence agriculture;Stable Government:o

5% on precious metals; and

3.5% on base metals and salts.

Corporate tax rate ~ 38%;

4. Potash – Why Potash?

5Large scale, long term projects, strategic asset;

Rising population and improving diets are driving foodconsumption growth and potash demand;

Potash is required to produce more food from a declining
per-capita land base;Price estimates of USD$350 – 400/t for 2010 and rising,peak price USD$1,000/t in 2008;

Short-term decline in fertilizer use is not sustainable –irreplaceable, reduced use cannot continue without
potential consequences for the global food supply;Upshot is the potash market has strong
fundamentals for demand growth;Recent deals include BHP offer of USD $39bn to acquire
Potash Corp and Mag Industries (TSX: MAA) option toCOMPLANT to purchase 50.1% of the Mengo Potash
Project in the ROC for debt financing of US$1.2b.

BHP is planning to build the largest potash mine in theworld. 8Mt p.a, capital cost USD$10.5bn;

Colluli Project initial potential target to define a
1.5Mt p.a operation, capital cost ~ USD$0.50.75bn and mine life exceeding 20 years.

NICKELASSETS

The potential for further mineralisation is supported by the interpretation of down-hole transientelectromagnetic (DHTEM) survey results from holes TBDD093 and TBDD098 which suggests thatthe strongest mineralisation is situated between these holes and continues steeply down plunge tothe north west.

JORC- Exploration Targets
It is common practice for a company to comment on and discuss its exploration in terms of target size and type. The information in thispresentation relating to exploration targets should not be misunderstood or misconstrued as an estimate of Mineral Resources or Ore Reserves.
Hence the terms Resource(s) or Reserve(s) have not been used in this context. The potential quantity and grade stated or implied is conceptual innature, since there has been insufficient work completed to define them beyond exploration targets and that it is uncertain if further exploration will
result in the termination of a Mineral Resource.
