Oobagooma/Yampi Uranium Deposit
See also : Anti-Nuclear Alliance of WAThis deposit occurs in a zone averaging 2 metres thick in sandstone, near Yampi in Western Australia. The deposit was originally owned by Afmeco Mining and Exploration Pty Ltd (AFMEX), a wholly-owned subsidiary of Cogema Australia.
The estimated reserve is 9,950 tonnes of uranium oxide (at a 300 ppm cut-off) with average grade of 0.12% U3O8. At a 0.1% cut-off there is some 3,000 tonnes uranium oxide at an average grade of 0.275% U3O8. In situ leaching appears to be the most likely method of extraction.
In February 1998, the deposit was placed on the market since Cogema intend to focus all of their development work on the Koongarra deposit. In June 1998, Paladin Resources, headed by John Borshoff (former Uranerz Australia manager), bought both the Manyingee and Oobagooma deposits. They announced their intention to develop the Manyingee deposit as an ISL mine within 2 to three years.
Acclaim Uranium are also active in exploring the Oobagooma region for further ISL-type uranium deposits.
