Three major mineralisation styles are present: auriferous, pyrite-rich greisenous zones such as those at Dargues Reef, Exeter Farm and Scotsmans Gully; gold–base metal-rich veins/lodes, including those adjacent to the Majors Creek village; and those deposits which have both greisen- and vein-type mineralisation, including those in the Snobs mine area, which takes in Snobs Reef (Snobs Lode–Stewart & Mertons–United Miners zone) and The Creek prospect.

Ore is mined using conventional bottom-up longhole stoping and trucked from the underground mine to a surface stockpile adjacent to the process plant. Stope voids are backfilled with cemented hydraulic fill or waste rock. Mine access is via a boxcut and decline from the surface.

- subscription is required.

The process plant has a permitted capacity of 355ktpa and comprises a three-stage crushing circuit, ball mill and two-stage flotation circuit producing a clean gold-rich pyrite concentrate. Process tailings are used for cemented hydraulic fill or deposited in a lined storage facility.

The ground ore will be directed to a rougher flotation circuit where rougher flotation concentrate and tail streams are separated by the addition of flotation reagents and low pressure air. The rougher concentrate will be directed to the re-grind circuit whilst the rougher tail will be dewatered via a thickener prior to transfer to the tailings storage facility.

Rougher concentrate will be ground within a re-grind ball milling circuit. Re-ground rougher concentrate will be transferred to the cleaner flotation circuit where further flotation will produce the final concentrate. The tail from the cleaner flotation circuit will be transferred back to the rougher circuit feed stream.
