DAISY COMPLEX
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, 800m across strike and 1,308m down dip and open at depth. These extents host approximately 74 known ore zones (ore domains).

MOUNT BELCHES CENTRE
MAXWELLS
The Maxwells deposit is hosted within the lower ‘Maxwells’ member. The Mount Belches group is located in the southern Eastern Goldfields Superterrane, Yilgarn Craton, Western Australia.

The iron formation is a silicate/oxide-facies unit with over printing sulphides, which has undergone metamorphism (upper-greenschist facies) and deformation (two generations of folds). The gold deposits are hosted in both the hinge zone and along the limbs of a regional scale, chevron folded BIF package.

Gold dominantly occurs as inclusions of native gold and/or electrum within or around pyrrhotite, magnetite, and arsenopyrite, and economic mineralisation is typically restricted ........

DAISY CENTRE
The Daisy Complex production sourced from Haoma West, Lower Prospect, Easter Hollows and remnant mining areas. The Easter Hollows zone provides a shallower mining front and a significant exploration opportunity, with 1,000 metres of known plunge extent and improved drill access to target infill and extensional opportunities. In FY23, ore from the Daisy Mining Centre will continue to be sourced from Haoma West, Lower Prospect and the Easter Hollows lodes.

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.

The mining methods employed in the study are mechanised development, longhole stoping and airleg mining which are all currently utilised at the mine.

Major assumption made for optimisation parameters include minimum stoping widths of 2.4m and maximum stope height of 15m.

Minimum mining width parameters for handheld 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.
