Increased production of uranium in Southern Africa 09 March 2010 Dr Roger Paul General Manager: Business Development
Price Long term prediction
Historic Production Highly enriched U, HEU Diluted for fuel
Nuclear Power Production • 437 in operation • 5 in long term shut down • 55 new plants under construction • 142 planned • 327 proposed Source: International Atomic Energy Agency, U.S. is from Energy Information Administration Updated: 9/09
Resource and Production Reasonably assured resources + inferred resources at $130/kg - World Nuclear Association 2007 Uranium production in 2006 - British Geological Survey

HPGR crushing vs conventional: evaluations underway to quantify any metallurgical advantages (leaching, heap leaching) Bio heap leaching: direct generation of oxidant (Fe3+) and acid (pyrite content) 3% pyrite reduced acid consumption by 50% Major IX developments: Re-estalishment of NIMCIX expertise Resin-in-Pulp Resin evaluations, improved resins Silica behaviour and management: effect of pH, adsorption time Direct precipitation from high grade eluate (>30 g/L U3O8) Continuous elution: novel approach Significant reduction in elution time CAPEX and OPEX potential savings Research & Development
Southern Africa’s uranium resources are under-invested Attainment of environmental targets easier in dry climate Good infrastructure in many countries Technological advances allow economic recovery at lower grades Availability of skilled engineers Conclusions
