Millipede-Abercromby

The three connected orebodies of the Centipede-Millipede-Abercrombie Uranium Deposit are located on the western edge of Lake Way, 32 km south of Wiluna in the East Murchison Mineral Field of WA.

This deposit made up an important part of Acclaim's regional strategy, being included in the 'Murchison Project' (see also Lake Maitland and Nowthanna). These calcrete deposits feature uranium-bearing carnotite at 2-5 metres depth. The deposit would be suitable for shallow, cheap open cut mining.

Both deposits were extensively drilled by ESSO in the late 1970s and 1980s, and Acclaim has followed this up with more drilling campaigns in 1998 and 1999 to prove the size of the resource. The orebodies are more irregular than Nowthanna or Lake Maitland, requiring much more drilling to get an accurate idea of how much uranium is in the ground. Acclaim declined this expense owing to the uncertain future of the industry. While smaller than Nowthanna, the deposits feature areas of much higher grade; results from one drill hole reading as high as 2.19 kg/tonne.

Acclaim intended to establish a uranium mill at Lake Maitland and then begin transporting raw or concentrated ore from Millipede/Abercromby to feed this mill.
