Glencore’s Australian coal output up 11%: logistics and scheduling notes for engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Glencore lifted Australian thermal and semi-soft coal output 11 per cent quarter-on-quarter to 17.5Mt in the September quarter, adding about 1.7Mt over June. The increase was driven by stronger production at the Ulan West longwall operation, signalling improved underground performance and fewer geotechnical or equipment-related constraints than earlier in the year. Higher run-of-mine volumes will pressure haulage, CHPP throughput and stockpile management across Glencore’s New South Wales assets, with potential implications for contractor demand and mine scheduling into 2025.
Technical Brief
- Reported volumes cover Australian thermal and semi-soft coal only, excluding coking coal tonnage.
- September-quarter figures are compared directly against June-quarter output for operational performance tracking.
- Production data are consolidated at national level, aggregating multiple open-cut and underground operations.
- Quarterly disclosure cadence enables short-interval review of mine scheduling, contractor utilisation and equipment deployment.
- Higher national output typically requires recalibration of rail paths, port allocations and stockpile live capacity.
- For similar multi-mine portfolios, such step-changes in ROM tonnage often trigger CHPP debottlenecking studies.
Our Take
Glencore’s stronger Australian coal output sits alongside weaker performance in some other commodities, with our recent coverage noting a 52% year-on-year fall in its cobalt production due to DRC export constraints, which may increase the relative strategic weight of stable coal cash flow in its portfolio.
Among coal-tagged pieces in our mining coverage, Australia remains one of the few jurisdictions where large incumbents like Glencore are still reporting volume growth rather than managed decline, which is likely to support continued contractor demand around established operations such as Ulan West in the near term.
