Granny Smith Gold Mine

Granny Smith Gold Mine is situated in the Goldfields-Esperance region of Western Australia, approximately 740 km northeast of Perth and 55 km northeast of Laverton, within the Mt. Margaret mineral field. The terrain is characterised by semi-arid, flat to undulating desert landscape with fine red-dirt particulate — a persistent abrasion and contamination vector for rotating equipment, filtration systems, and hydraulic components. Suppliers of air filtration, dust suppression, and wear-resistant consumables face sustained demand driven by this environment.

Extractive services required across the underground operation include:

• Underground contract mining: trackless fleet support, long-hole drill rigs, charge-up and explosives services
• Ground support systems: rock bolting, mesh, shotcrete, cable bolting for deep stoping geometries
• Active ventilation and refrigerated air cooling infrastructure, critical at depth
• CIP circuit reagents, carbon management, and processing plant maintenance
• On-site workshop and mobile mechanical services to minimise costly unplanned downtime in a remote setting

Logistical services include FIFO charter flight coordination, on-site catering, camp facilities management, and heavy road-train transport along the site haulage corridor.

The Wallaby deposit is extracted via multiple underground stoping methods — inclined room and pillar, transverse and narrow-vein long-hole stoping, and bulk long-hole stoping — reflecting a complex, high-grade orebody geometry at significant depth. Trackless haulage transports ore to surface for processing through an on-site carbon-in-pulp (CIP) circuit. Increasing mining depth intensifies requirements for ground control engineering, extended ventilation networks, and chilled-air delivery systems. On-site dual-fuel and hybrid power generation supports continuous operations.

Gold Fields is actively advancing decarbonisation at Granny Smith through an expanding hybrid energy system combining solar generation and battery energy storage, reducing diesel dependency at site. Underground battery-electric vehicle trials are underway, targeting lower emissions and improved air quality in deep workings — a direct procurement signal for EV-compatible charging infrastructure and fleet transition services. The operation holds ISO 14001 and OHSAS 18001 certifications and complies with the International Cyanide Management Code, underpinning a structured ESG value chain for suppliers seeking long-term alignment.
