The Williamson deposit is situated on the Wiluna Mine Sequence covering 6km of strike with multiple mineralised structures. The Williamson Mine Centre currently has JORC resources of 7.1Mt @ 1.6 g/t for 360,000 ounces of gold. The Williamson Mine Centre also has an Exploration Target of 0.5 – 2Moz (4.4–11Mt, 2-6g/t au)1. Williamson is only 26km to the Wiluna Gold Plant and 10kms from the Matilda Mine by existing haul roads. The Williamson open pit was last operated by Agincourt and produced around 668,000 tonnes @ 1.98 g/t gold for a total of 42,000 ounces and ceased in September 2006, when the gold price was A$770/oz.
Mineralisation occurs as weakly disseminated sulphides within a broad anomalous envelope around a north striking/east dipping monzogranite. Higher grade sulphide and visible gold mineralisation is associated with the shearing on the contacts of the granite and also within a west dipping shear that intersects the monzogranite. Mineralisation within the monzogranite body varies from broad low grade disseminated sulphides in the monzogranite to high grade veins formed within fractures containing visible gold.
* The Company’s exploration target includes potential quantity and grade and is conceptual in nature. There has been insufficient exploration to define mineral resources and it is uncertain if further exploration will result in the determination of mineral resources.
