8-Mile Dam

Eight Mile Rock Hole is situated within the Goldfields-Esperance region of Western Australia, in close proximity to Coolgardie — a strategic node on the Great Eastern Highway corridor. The terrain is characterised by flat, semi-arid scrubland with lateritic soils and fine red dust (red dirt) permeating all surface operations. This airborne particulate environment creates acute demand for high-efficiency filtration systems across all mobile and fixed plant, accelerating wear rates on seals, bearings, and air intake components.

Operated by MLG Oz, the quarry supplies screened and unscreened silica sand and construction aggregates to regional mining operations, civil contractors, and infrastructure developers across the Goldfields. The operating model is DIDO-based, drawing labour from Kalgoorlie-Boulder. Given the remote setting, unplanned equipment downtime carries severe cost implications. Access to local mobile mechanical workshops and rapid-response field service providers is a critical procurement priority for site continuity and SLA compliance.

Material handling at the site relies on conveyor-intensive processing circuits — screening decks, transfer points, and stockpile conveyors operating under continuous abrasive silica load. Belt wear, idler failure, and chute liner degradation are primary maintenance vectors. The abrasive index of silica sand demands premium-grade polyurethane screen panels and ceramic-lined transfer chutes. Engineering procurement should prioritise conveyor component standardisation and on-site spare parts inventory to minimise mean time to repair (MTTR) across crushing and screening assets.

MLG Oz has publicly committed to ESG-aligned operational frameworks, including fleet electrification pathways and fuel consumption reduction targets across its quarry network. At Eight Mile Rock Hole, opportunities exist for solar-assisted auxiliary power to offset diesel dependency in fixed plant operations. Dust suppression programmes — critical for both community compliance and Scope 1 emission reduction — represent an active ESG lever. Procurement partners offering low-emission haulage solutions or renewable-integrated site power systems align directly with MLG Oz's decarbonisation trajectory.
