As part of a multidisciplinary study of the region by Geoscience Australia and the geological surveys of New South Wales and Queensland, the mineral systems at the Cuttaburra and F1 prospects have been investigated with the aim of better understanding the prospectivity of the southern Thomson Orogen. Samples from three drill holes at the Cuttaburra prospect and three drill holes at the F1 prospect were studied in detail petrographically and analysed for the following: whole-rock geochemistry; S isotopes; Pb isotopes; molybdenite Re-Os geochronology; cassiterite U-Pb geochronology; and white mica 40Ar/39Ar geochronology. The results have been integrated with existing zircon U-Pb geochronology and company data to better characterise the geology, mineralisation, alteration, timing and geochemistry of the mineral systems. A new two-stage model of mineral system formation has been developed in which early Mo-W and later Au-base metal mineralisation both formed at ~425-430 Ma, probably coevally with granitoids that intruded Cambrian or younger metasedimentary rocks.
