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 remai ........

Mining of the Project has been assumed to be by a combination of open pit and underground methods. The open pit mine life is currently projected to be approximately mined in conjunction with underground operations. The selected mining method, design and extraction sequence are tailored to suit orebody characteristics, minimise dilution and ore loss, utilise planned process plant capacity and expedite free cash generation in a safe manner. Mining schedules have been based on realistic mining productivities with readily achievable mining rates along with consistent material movements.

Contractor mining will be undertaken from three open pits using standard truck and shovel mining methods with the Minyari deposit accounting for 90% of the open pit gold mining production. The open pit lower economic cut-off grade was determined to be 0.30 g/t.

Contractor mining will also be undertaken for the Minyari deposit underground using Modified Sub-Level Caving (M-SLC) mining methods. The Minyari South open pit will also act as the box-cut for the Minyari deposit underground portal and decline. The Minyari underground lower economic cut-off grade was determined to be 1.50 g/t. Based on the conceptual underground mine design the decline is also an optimal drill platform for delineating and accessing underground resource growth and mining opportunities including the Minyari and WACA plunge targets, Minyari South and Sundown.
