In the presentation Mr Langworthy highlights the significant exploration opportunity at the Company’s flagship Gidgee Gold Project in Western Australia, including:

• The project’s strategic location in the under-explored Gum Creek Greenstone Belt in Western Australia;

• The strong geological analogies between the Gidgee Project at the Tarmoola-King of the Hills and Granny Smith deposits in Western Australia, including the significant exploration opportunity along the contact between the Montague Granodiorite and the ultramafic host rock – a similar position to that currently being targeted by WA gold company Red 5 at the King of the Hills Project;

• The Company’s strategy to build a large free-milling resource base at Gidgee capable of sustaining a midtier scale gold business while also considering sensible consolidation and expansion opportunities in the district; and

• An update on recent and upcoming drilling at the Whistler and Montague Deposits and upcoming news-flow.
