DAISY CENTRE
The Daisy Complex production primarily sourced from Haoma West and Easter Hollows, which accounted for 80% of tonnes mined for the year. In FY24, ore from the Daisy Complex will be predominantly sourced from the 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.
MOUNT BELCHES CENTRE
The Mount Belches underground mines, Maxwells and Cock-eyed Bob (CEB), were suspended in early FY23 to allow Silver Lake to preserve the value of the Maxwells and CEB Mineral Resources and Ore Rese ........
