Segilola is an orogenic-style lode gold deposit which occurs within a regional-scale shear zone.

Host rocks comprise an overturned sequence of high-grade amphibolite-facies metasediments intruded by a large, possibly differentiated, granodiorite sill-like body. The mineralisation is developed within a series of steeply dipping, tabular, very continuous, latestage quartz-pegmatite veins that do no exhibit any form of significant deformation such as folding or faulting. The geological and mineralogical characteristics of the mineralised veins are consistent throughout both the strike and down dipextents of the known resource.

Drilling results demonstrate that gold mineralisation occurs in fractured pale to dark grey coloured smoky quartz veining, sheared pegmatite, and silica/chlorite/carbonate alteration. The mineralisation is hosted in three steeply dipping vein sets or lodes; the Hanging Wall Lodes (Lodes 100 and 300) and the Footwall Lode (Lode 200). Together these form an elongate mineralised zone striking 010º and dipping 60º to 70º towards the west within a single shear zone, primarily in biotite gneiss. The currently drilled mineralised zone is approximately 2,000 m in strike length, between 70 m and 200 m in depth, and between 2 m and 20 m in true thickness.

The mineralogy of the Segilola deposit is characterised by its general simplicity and consistency. The gold is entirely non-refractory and commonly occurs as visible particles wit ........

The Segilola Gold Project will be operated primarily as a contract mining operation with all mobile equipment to be provided, operated, and maintained by a mining contractor(s) over the life of the Project. Conventional open pit mining methods using excavator and truck fleets will be used. Thor will provide fixed installations including contractor area establishment, workshops, offices, and first aid facilities.

There are four well defined weathering horizons present, allowing the material to be mined according to classification as residual soil, oxide rock, transitional rock, and fresh rock. The vast majority of material is fresh rock.

Drilling rigs operated by the contractor will be Epiroc T45/50 class top-hammer drills with the capability to drill holes from 89 mm to 140 mm in diameter. Ore blasting will be done on five metre benches, while waste blasting will be conducted on 10 m benches where possible. A set of blast patterns ranging in powder factor from 0.43 kg/m3 to 1.07 kg/m3 will be applied depending on the material type.

Narrow ore zones will require the implementation of careful blasting techniques to minimise dilution and maximise ore recovery, namely the use of “Blastmaster” bench planning to optimise blast shapes/geometry and sequencing, choke firing where possible to minimise ore movement, blast initiation timing to control movement, the use of blast movement indicators, and a refinement of blast design parameters based ........

The plant is designed to operate 365 day/year, 24 hours/day, with a design utilization of 91.3%, for a nominal ore throughput of 81.3 tph and design ore throughput of 84.5 tph. Production throughput utilises 86.6% of design utilization, resulting in an average LOM annual production of 625,000 tpa.

The process plant was initially designed for a ROM throughput of 500,000 tpa. During the DFS study, to better align with the mine design and optimise project economics, the process plant throughput capacity was increased to 650,000 tpa. This increase in size of the processing facility also allows for operating flexibility and future expansion capacity.

The ROM pad will be located at the south east corner of the plant site. ROM with a nominal top size of 600 mm will be delivered by haul trucks from the open pit mining operation and will either be dumped directly into the ROM bin, or stockpiled on the ROM pad. If oversize rocks bridge the static grizzly, a mobile rock ........
