Extension approved for Dartbrook mine
The NSW Government has approved a six-year extension to the Dartbrook coal mine in the Hunter Valley, allowing operations to continue until December 2033.The mine’s current license allows for extraction of up to 6mtpa of coal and is valid until the end of 2027.The site has a history of financial challenges. The Dartbrook coal mine was placed into care and maintenance in late 2025, less than a year after new owners relaunched operations, after entering voluntary administration and receivership in July. This decision came after operators defaulted on a $202m loan.Later that month, as its financial standing deteriorated mass redundancies occurred across the site that saw a workforce reduction of about two-thirds.According to an economic analysis conducted by the NSW Government, the extension, known as MOD8, has a projected net benefit to the economy of $471m, including $73m in gross wages, 240 direct jobs and 613 indirect jobs.If the maximum extraction rates were realised, the total revenue would extend to $1.28b, according to the NSW Government.Muswellbrook Shire Council has been supportive of the extension but has conveyed concerns if any further extensions were to be considered.In a letter to the NSW Department of Planning, Housing and Infrastructure, Muswellbrook Shire Council environmental planning director Sharon Pope said the original mine approvals were given in 2001 and were supported by an environmental impact statement (EIS) dated 2000.“Staff remain concerned that the original EIS no longer reflects current standards,” she said.“The age of the baseline data raises doubts about its reliability. Given these uncertainties, staff recommend no further time extensions after MOD8 unless comprehensive, up-to-date assessments are completed.”Underground mining has been approved at Dartbrook since 1991, however mining only occurred between 1996 to 2006.The previous operator, Anglo American, mothballed the site in 2006 following a series of safety challenges and operational concerns and three worker fatalities. The site had been idle for 19 years prior to the initial restart in 2024.
