Uranex NL announced the findings and implications for potential processing of ore at the Manyoni Project. Preliminary acid leach testwork results conducted during the Scoping Study phase of the current Manyoni Study have returned uranium recoveries of up to 90% in short leach timeframes. A flowsheet consisting of scrubbing, size reduction to -1 mm and conventional acid leaching is emerging as the most likely method for treating this ore. The unusual water soluble uranium mineral, schrockingerite, is present in significant quantities in all the clay samples. Consequently, between 30% and 80% of the Uranium in these clay samples is recoverable into solution simply by slurrying the ore in water at room temperature for 20 minutes
Uranex confirms the commencement of the Pre-Feasibility Study for its Manyoni Uranium Project in Central Tanzania, following positive scoping study results, with the appointment of internationally recognised AMC Consultants in Melbourne as the project manager to complete the study. The study is scheduled for completion by December 2009. Additional geological exploration and drilling on identified prospects will also be carried out during the study period in the Manyoni and Bahi regions, in line with this development.
Uranex NL reported initial uranium (U3O8) resource estimates for its 100% owned uranium projects, Thatcher Soak in Western Australia, and Bahi in central Tanzania. Independent consultants Hellman and Schofield Pty Ltd (H&S) have estimated an Inferred resource at Thatcher Soak of 17 million tonnes, averaging 290ppm U308 for a contained U308 content of approximately 11 million pounds (or approximately 4,900 tonnes contained U308), at a cut off grade of 150ppm U308.
