Olary Creek

(U3O8 Limited 100%)

Major palaeochannel defined by gravity survey

The Olary Creek project is located some 250 kilometres north east of Adelaide and covers an area where younger Tertiary sediments on-lap Proterozoic basement along the northern margin of the Murray Basin. Anomalous concentrations of uranium (up to 0.1% U₃O₈) are known in carbonaceous sediments near the northern basin margin. Olary Creek Project Tertiary sequences on the edge of the Murray Basin are prospective for palaeochannel style uranium mineralisation (Beverley, Honeymoon) in drainages shedding from the nearby hardrock Radium Hill deposit which was the site of Australia's first uranium mine. Previous drilling located uranium mineralisation in the basal part of the Miocene sand sequence along the north-east trending Anabama-Redan fault zone and in a major tributary further north, close to the current course of Olary Creek. Most previous drilling focused on the Anabama Fault zone to the south of U3O8's tenement while the tributaries from the likely source region around Radium Hill which pass through EL3454 are lightly explored.

Olary Creek Project - Regional Geology and Prospects

U3O8 Limited completed one brief drilling programme at Olary Creek in 2006. Eight holes were completed for 230 metres due to limited rig availability. The broad spaced holes were drilled across the current drainage in an attempt to identify the extent of any buried palaeochannel. Only the margin of the channel was identified and no significant results were returned from the programme.

In an effort to clearly define the extent of the buried palaeochannel, U3O8 Limited completed a detailed gravity survey over part of the exploration licence. The gravity survey covered 80km²for a total of 485 stations, 200 metres apart and along one kilometre east-west traverses.

The survey clearly defined a significant buried channel system with tributaries running into it. A drilling programme is planned to test the geological characteristics of the palaeochannel and the presence of uranium mineralisation. The programme will be completed in the December 2007 Quarter.
