The Nowthanna mining lease ML 51/771 is located 47 km south east of Meekatharra and is accessible from the Great Northern Highway.
The tenement covers a portion of the calcrete Palaeo-channel near the Quinn’s Lake inland drainage. The predominant minerals are developed from extensive weathering and leaching of uranium-bearing domes and nearby Archaean mafic and ultramafic rocks that are high in vanadium. In the late 1990s Acclaim Uranium NL actively explored the Nowthanna area and drill defined a historic resource which was confirmed by Yellow Rock Resources in 2012. The JORC 2004 compliant Indicated Resource on ML 51/771 is 3,059,000t @ 0.437 kg/t U3O8 (see ASX announcement dated 20 December 2012).
No new uranium mining is currently permitted in Western Australia.
