The deposit type is classified as an orogenic gold deposit within the Norseman-Wiluna greenstone sequence. The accepted interpretation for gold mineralisation is related to (regional D2-D3) deformation of the stratigraphic sequence during an Archaean orogeny event.

Locally, the mineralisation is characterised as a deformed vein, hosted within intermediate volcanic and volcaniclastic units and closely associated with felsic intrusive rock types of the Gindalbie Terrane. The metamorphic grade is defined as lower green-schist facies.

The Daisy Complex resource extents are 2,200m strike, 700m across strike and 1,200m down dip and open at depth. These extents host approximately 78 known ore zones (ore domains).

Mining at Daisy Complex utilizes a single boom jumbo for ore development and longhole stoping between sill drives. All stope panels are assumed to have a minimum width of 2.4m and variable dilution is added at 0.0 g/t when mining each stoping block.

Major assumption made for optimisation parameters include minimum stoping widths of 2.4m and maximum stope height of 15m. Minimum mining width parameters for hand held and mechanised mining were set at 2.4 metres, based on current experience at the Daisy Complex. An additional 20% dilution factor is then applied. Mining recovery factor of 80% was applied to account for ore loss in pillars and unplanned ore loss. Infrastructure to support mining operations is already in place at the Daisy Complex.

Daisy Complex feeds the 1.3Mtpa Randalls mill.

Reasonable assumptions for metallurgical extraction are based on metallurgical processing the Daisy Complex ore through the Randalls (CIL) process facility. The current recoveries for gold are greater than 94%.
