Premier Coal

Premier Coal 1 Deep is situated within the Collie River Mineral Field, South West Region of Western Australia, approximately 200 km south of Perth. The Collie Basin presents a moderately undulating terrain underlain by Permian-age coal measures. Intense seasonal rainfall events — characteristic of the South West's Mediterranean-to-temperate transition zone — generate significant haul-road mud loading, demanding continuous geotextile reinforcement, road-base stabilisation compounds, and dedicated grader cycles to maintain trafficability on primary truck access corridors.

The asset operates under active production status, managed by Yancoal Australia on behalf of majority shareholder Yankuang Energy Group. As a deep underground operation within a mature basin, the site demands rotating shift rosters with logistical complexity typical of FIFO/DIDO hybrid workforce models. Personnel welfare infrastructure — including crib rooms, ablution facilities, and emergency refuge chambers — must meet stringent Mines Safety and Inspection Act (WA) standards. Third-party camp and catering service vendors should note the proximity to Collie township as the primary workforce accommodation hub.

Underground coal extraction at depth requires a robust primary crushing and conveying circuit interfacing with surface coal handling and preparation plant (CHPP) infrastructure. The Collie sub-bituminous coal grade necessitates precise flotation circuit calibration and dense-medium cyclone (DMC) separation to achieve target product ash and moisture specifications. Key engineering supply categories include:

• Longwall or continuous miner roof support systems
• Underground ventilation fans and methane monitoring arrays
• CHPP reagent dosing and froth flotation cell maintenance
• Conveyor belt vulcanisation and tensioning services
• Dewatering pump stations for high-inflow underground headings

Operating within the South West of WA, Premier Coal 1 Deep is subject to Aboriginal Heritage Act compliance obligations, requiring due-diligence surveys prior to any ground-disturbing works or infrastructure expansion. B2B procurement strategies increasingly prioritise engagement with Noongar-owned enterprises and registered Indigenous businesses under Closing the Gap supply-chain frameworks. Environmental obligations include:

• Mine void water quality monitoring under DER licence conditions
• Progressive rehabilitation and landform reconstruction commitments
• Greenhouse gas reporting under NGER Act (Scope 1 & 2)
• Biodiversity offset management for jarrah forest interfaces
