Doolgunna Station, WA (AUC interest 100%)
The Doolgunna Station project is located 150km north-east of Meekatharra and approximately 13km to the west of, and along trend from, Sandfire Resources’ Degrussa copper-gold operation in Western Australia’s Bryah Basin. The project tenement E 52/3031 covers 192km2.
In 2017 Ausgold completed a technical review and field assessment that demonstrated the potential for Doolgunna Station to host Degrussa-style Volcanic Hosted Massive Sulphide (VHMS) and Plutonic-style orogenic gold deposits.
Reinterpretation and enhancement of aeromagnetic data collected by Ausgold in 2010 highlighted north-east striking shear-bounded structural corridors similar to those that host Plutonic-style mineralisation. These corridors were the focus of a soil sampling program in July 2017 and warrant further investigation.
Elevated copper values in aircore drilling are associated with a late north-east striking fault that has cross-cut two prospective horizons for VHMS mineralisation:
The copper anomalism is considered to be secondary leakage haloes that have migrated along the north-east fault. Reinterpretation of VTEM and aeromagnetics flown by Ausgold in 2010 highlighted untested VTEM conductors associated with the large magnetic and conductive body that lies within the Peak Hill Schists.
Ausgold is planning additional aircore drilling to delineate mineralisation along the contact between the Peak Hill Schists and the prospective Naracotta Volcanics. The focus of this drilling will be the identified copper anomalism and VTEM targets.
