Mount Hamlet Project
The Mount Hamlet tenement demonstrates good exploration potential for vein and hydrothermal U-Cu-Bi-Au mineralisation, unconformity-related and granite-related uranium mineralisation. Geologically, the tenement contains:
1. Gascoyne Complex
a. Morrissey Metamorphics, consisting of pelitic and psammitic schist, calc-silicate rock and minor amphibolite
b. Moorarie Supergroup gneisses
2. Ashburton Basin sediment of the Upper Wyloo Group, which is believed to be age equivalent to the Gascoyne Complex
3. Mangaroon Orogeny
a. Pooranoo Metamorphics, which consist of pelitic schist, metamorphosed feldspathic sandstone and conglomerate and metamorphosed dolomite
b. Durlacher Supersuite granites
4. Bangemall Basin basal unit; the Uaroo Group
Structurally, the tenement is dominated by N-S faults, with a major shear zone (355 degree orientation) running the entire length of the project area. Late-doleritic dykes also form along these earlier shear / fault zones. The NW corner of the tenement is dominated by a synformal elongate basin which contains Upper Wyloo Group and the Uaroo Group unconformable contact.
The area that covers the Mount Hamlet tenement has had various phases of exploration since the 1970’s and has shown evidence of mineralisation throughout, with several prospects identified.

- Rock chip sample at Mt Hamlet returned 4.4% Cu, 1.1% Bi, 100ppm Ag and 85ppm U3O8
The Mt Hamlet Project consists of two 100% owned granted exploration licences in the Gascoyne Province of Western Australia. Mt Hamlet is approximately 40 km south of the Manyingee uranium deposit.
A heritage agreement was completed with the traditional Budina people and tenement E08/1994 was granted on 21st April 2010 for a five year term.
Field validation and surface rock chip sampling of a number of targets identified from aeromagnetic data and historical reports was undertaken. Sixty two surface rock chip samples were collected and analysed for a range of elements. Best results include 729 ppm U3O8 in calcrete from sample #6115 and 4.4% Cu, 1.1% Bi, 100ppm Ag and 85ppm U3O8 in a quartz vein from sample #6104.
