HVO case for Hunter coal to 2045: mine design and sequencing notes for planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Public hearings have opened on extending Hunter Valley Operations near Singleton, with the New South Wales Independent Planning Commission considering approval for coal mining to continue until 2045. The proposal would retain more than 1500 direct on-site jobs and secure several billion dollars in ongoing capital and operational expenditure across the large open-cut complex. For geotechnical and mine planners, a 21‑year life extension would lock in long-term strip sequencing, waste emplacement design and progressive rehabilitation commitments under evolving NSW planning and emissions policy settings.
Technical Brief
- Extension decision centres on Hunter Valley Operations open-cut complex near Singleton in New South Wales.
- Assessment is being conducted by the New South Wales Independent Planning Commission via formal public hearings.
Our Take
Coal pieces in our database are a minority within the 1247 Mining stories, so a proposal to keep Hunter Valley Operations running to 2045 signals that long-life thermal coal assets in New South Wales are still being actively advanced even as many peers pivot coverage towards metals.
With around 1500 direct jobs tied to the Hunter Valley Operations near Singleton, any New South Wales Independent Planning Commission decision will have outsized leverage in future approvals for large-scale coal in the Hunter Valley, as it will be read as a precedent on how socio-economic benefits are weighed against decarbonisation policy.
For operators in the Hunter Valley, an approved operating horizon out to 2045 would likely justify further investment in overburden removal, haulage fleets and CHPP upgrades, whereas a shorter consent window would typically push mine plans towards higher-grading and accelerated cash extraction rather than long-term optimisation.
