• 10 titles in the Mount Isa/ Cloncurry region . World’s most prolific producer of base metals. Key gold copper/gold targets plus potential for uranium and phosphate.
•Malmsbury gold project has a resource of 59,000 ounces and drilling to date confirms the potential to extend the resource and gold mineralisation over 2.5km strike. Interpreted as IRGD.
•Consolidation of the Dee Range copper gold project which lies near the Mt Morgan mine ( produced 8M ounces Au and 400K Cu). Gold and copper mineralistion is widespread.
•Willaura project is targeting the potential for a significant copper –gold system. Results from the adjacent tenement demonstrates the prospectivity of the Mt Stavely volcanic area.

Dee Range ProjectDee Range Project Copper mineralisation is widespread throughout the area.
The Dee Range and Smelter Returns Prospects cover an aeromagnetic anomaly suggesting an intrusive complex with features similar to Mt Morgan.
Mt Morgan lies 20km north-east and produced 8 million ounces of gold and 420,000 tonnes of copper.
Black range has a 4.5km anomalous zone with stream samples up to 171 ppb of gold.
There has been no drill activity since 1966 on the old Dee Copper mine.
Major structures transect the project.
The Smelter Return Prospect is associated with a significant skarn development hosting shallow intersections of 8m @ 0.8 g/t Au and 0.3% Cu in last drilling completed over 25 years ago.

Willaura – Project SummaryWillaura – Project Summary Target - Porphyry Cu Au deposit (Geologically similar to Cadia, Mt Lyell and North Parkes)
Targets defined by geochemical, geological, structural and geophysical data
This area is one of the most under explored volcanic area in Australia
Adjacent tenement results include 6m@3%Cu and 1.1g/t Au and 7.7m @ 4.2%Cu and 1.1g/t Au associated with the serpentinite which trends through EL4631gbgb
