Geological setting and mineral system The prospect occupies the Goodradigbee Graben between the Cowra Trough and the Cotter Horst, where the Koorabri Fault — a splay of the first-order Long Plain Fault — juxtaposes Lower Silurian limestone–chert–shale sediments against the Lower Devonian Mountain Creek Volcanics (Quek 1980a, R00016067). A calc-silicate corridor (clinopyroxene–garnet–epidote–actinolite, locally barite-bearing) of ~3–5 km strike and up to ~80 m apparent (outcro

Geological setting and mineral system Two prospects, one tenement application, on the Silurian volcano-sedimentary belt of the Captains Flat–Goulburn Synclinorial Zone, eastern Lachlan Orogen — the belt hosting the Woodlawn and Captains Flat Cu–Pb–Zn–Ag VMS deposits (R00005792). At Clare, gossans with box-work after sulphides sit at a sediment–volcanic contact with a footwall limestone in CD2; the NSW Department of Mines assessing geologist (L. A. Gilligan, 9 September 1974)

Geological setting and mineral system The three prospects sit in a fault-bounded Silurian volcanic–sedimentary basin of the eastern Lachlan Orogen, hosted by the same lithostratigraphic package (Westmead Park Formation of Smith 1965, equivalent to Canberra Formation unit Smc of Abell 1992), on the belt that hosts Woodlawn and Captains Flat in correlative Silurian stratigraphy (Nisbet 1979, GS1979/129, R00015991). Two complementary deposit-style models are supported by the evi

Geological setting and mineral system The target sits at the Curnamona Province – Delamerian Orogen boundary within the outcrop-poor Thomson cover region, beneath approximately 442 m of Eromanga/Darling Basin cover; basement is interpreted as probable Middle to Late Neoproterozoic quartz-rich shallow-marine clastics (R00036180). The intersection is recorded in GSNSW MinView as MIN_043525 (drill type Other — water bore; business purpose metallic minerals), with the mineralisat
