This licence is 100% owned by UXA, and covers an area of granite intrusions forming the basement to the Eclipse Sandstone (Ngalia Basin) that hosts Energy Metals’ Bigrlyi uranium deposit, 30km to the west.
Crystal Creek is an advanced uranium project within the tenement where in July 2009, UXA announced the discovery of a zone of outcropping uranium mineralisation spanning a strike distance in excess of 3,000m, with early field sampling indicating excellent U
3O
8 point concentrations of up to 4,120 ppm.

Uranium is associated with ironstone and is hosted in an East Northeast bearing shear within greisenised (altered) monzogranite of the Southwark Granite Suite, part of the Arunta Inlier. The structure can be traced for a distance in excess of 3,000m and varies in width from 30cm to 12m, averaging 3m.
Drill results confirm structurally controlled uranium mineralisation to continue at depth with more significant values occurring at the western third of the 3 kilometre long ironstone structure. Uranium mineralisation occurs in a number of parallel structures and remains open down dip.

The Company will undertake structural studies at Anomaly B to help identify controls on mineralisation prior to embarking on further drilling.
UXA believes potential may exist to identify other larger mineralised structural features within the tenement in close proximity to the Crystal Creek project and as such, the company will expand its exploration focus within the tenement in the year ahead comprising structural mapping, intensive geochemical sampling and further drilling.
