OKLO URANIUM LIMITED
STRATEGIC OBJECTIVE

• To delineate and develop sedimentary-hosted
  uranium and unconformity style uranium deposits -
  on a world wide basis
• and
• To develop Oklo into a mid-tier uranium producer
  within 5 years - through discovery and acquisition

8
OKLO URANIUM LIMITED
OKLOS URANIUM EXPLORATION MODEL
IS BASED ON THE TERTIARY URANIUM DEPOSITS OF
NAMIBIA

• Economic palaeo-channel-hosted uranium deposits,
  like Langer Heinrich (Namibia) and Yeelirrie
  (WA), occur in upstream parts of Tertiary
  drainage systems that are close to the source of
  uranium sub-economic deposits like Klein
  Trekkoppie (Namibia) occur down-stream
• Therefore
• We are targeting palaeo-channels in up-stream
  sections of palaeo-drainage systems that are
  close to the source of uranium (such as hot
  granites, u-rich sediments and/or unconformities)
