Mineralisation at both Minyari and WACA is hosted predominantly within hydrothermally altered metasediments. There are several mafic bodies identified in the project area, predominantly dolerite, which are variably mineralised, along with late felsic intrusive dykes that cross-cut the deposit area and are generally unmineralised. The resource has been depleted in these lithologies. The Proterozoic rocks are overlain by transported overburden, typically desert/dune aeolian sand which varies in thickness up to 10 metres. The Minyari and WACA deposits precious (gold and silver) and/or base metal (copper and cobalt) mineralisation is interpreted to be reduced intrusion-related, with local controls on mineralisation related to variations in both the competency/hardness and chemical composition of rock units, in combination with other discrete structural controls such folding, faulting, fracturing, veining, brecciation and associated hydrothermal alteration and mineralisation (including sulphides) being the key factors influencing mineralisation grade and continuity. The Minyari deposit constitutes approximately 85% of the gold resource and 96% of the Scoping Study mining inventory gold ounces. Minyari mineralisation is generally moderate to steeply dipping and is hosted by a plunging pipe-like breccia body located in the hinge and both limbs of an interpreted synform. The true-thickness of mineralisation ranges from 5 to 120m and extends from surface to a depth of 670m and remains open down plunge to the northwest. In the Minyari deposit area there is also near-surface, sub-horizontal soil/calcrete hosted re-worked/remobilised “channel” style low-grade gold mineralisation, located above the Proterozoic basement.
