Gordon Sirdar Gold Mine

Gordon-Sirdar Openpit is situated near Kanowna, approximately 15 km northeast of Kalgoorlie-Boulder within Western Australia's Goldfields-Esperance Region — one of the most geologically prolific yet climatically hostile gold corridors on Earth. The terrain is characterised by flat, semi-arid scrubland with extreme diurnal temperature swings exceeding 40°C in summer. Water supply infrastructure is operationally critical; the region relies on the Goldfields Water Supply Scheme (Mundaring pipeline network) and on-site storage solutions to sustain processing and dust suppression continuity.

Currently in active production phase, Gordon-Sirdar operates under FMR Investments, which inherited operational frameworks from Barminco's mining services legacy. The open pit configuration demands continuous engagement with mobile plant maintenance contractors — particularly for drill-and-blast, load-and-haul fleets, and tyre management. Proximity to Kalgoorlie-Boulder provides access to a dense ecosystem of OEM dealers and mechanical workshops, reducing critical equipment downtime risk. Vendors supplying wear parts, hydraulic components, and ground support consumables should target Kalgoorlie as the primary B2B logistics node.

• Primary procurement hub: Kalgoorlie-Boulder industrial precinct
• Drill-and-blast consumables (ANFO, detonators, stemming)
• Load-and-haul fleet maintenance (tyres, GET, hydraulics)
• Dust suppression and water cartage services
• Site survey and grade control instrumentation

As a gold-bearing open pit operation in the Eastern Goldfields, Gordon-Sirdar's ore is expected to be processed via conventional carbon-in-leach (CIL) or carbon-in-pulp (CIP) circuits, consistent with regional processing standards. The primary grinding circuit — typically SAG/ball mill configuration — demands precise liner management, mill media consumption tracking, and reagent dosing control (cyanide, lime, activated carbon). Flotation pre-concentration may be applied depending on sulphide ore fractions. Physico-chemical parameters including pH buffering, dissolved oxygen, and leach residence time are tightly regulated to maximise gold recovery efficiency.

• SAG/ball mill primary grinding (liner and media supply opportunity)
• CIL/CIP leach circuit — cyanide and lime reagent supply
• Activated carbon management and elution systems
• Gravity concentration pre-treatment (potential)
• Tailings storage facility (TSF) management and geotechnical monitoring

Operating within WA's increasingly stringent ESG reporting environment, FMR Investments faces mounting pressure to align Gordon-Sirdar's operational footprint with decarbonisation benchmarks. The Goldfields region is a focal point for hybrid solar-diesel microgrids, with several neighbouring operations already deploying large-scale renewable integration to reduce Scope 1 emissions. Electrification of light vehicle fleets and haul truck hybridisation represent near-term transition pathways. Tailings rehabilitation, native vegetation offset programs, and First Nations engagement protocols under WA's Aboriginal Cultural Heritage Act 2021 are non-negotiable compliance pillars for continued operating licence integrity.

• Solar-diesel hybrid grid integration (regional benchmark)
• Scope 1 & 2 emissions reduction targets — fleet electrification pathway
• TSF closure planning and progressive rehabilitation
• Aboriginal Cultural Heritage Act 2021 compliance
• Water recycling and zero-discharge tailings management
