BHP Reportedly To Halt Saraji South Mine Operations, Cut 750 Jobs Amid Royalty Pressure

BHP Group Ltd and Mitsubishi Development will suspend operations at their Saraji South mine in Queensland by November 2025, citing persistently low coal prices and high state government royalties that have eroded profitability. This strategic decision, impacting approximately 750 jobs across BMA's Queensland operations, underscores the challenges facing coal producers in high-cost jurisdictions and reflects the joint venture's focus on optimizing its asset portfolio despite strong medium-term demand for hard coking coal.

Analysis

The BHP Mitsubishi Alliance (BMA) is strategically suspending operations at its Saraji South coal mine in Queensland, Australia, effective November 2025, a decision directly attributed to eroded profitability. According to the company, the primary drivers are persistently low coal prices combined with high state government royalties, which have rendered operations in the mine's lower-margin zones economically unviable. This move to place the asset into "care and maintenance" will eliminate approximately 750 jobs and highlights a deliberate effort by BHP and Mitsubishi to optimize their asset portfolio for greater sustainability and profitability. It is particularly noteworthy that this decision is being made despite a strong medium-term demand forecast for hard coking coal, indicating the problem is not a lack of end-market demand but rather a severe margin squeeze from operational costs and fiscal policy. The mothballing of Saraji South serves as a clear signal of the acute financial pressures facing coal producers in high-cost jurisdictions.

Key Decisions for Investors

• While the closure negatively impacts near-term production volumes for BHP and Mitsubishi, it should be viewed as a disciplined capital allocation decision to shore up portfolio-wide profitability by exiting a high-cost, low-margin asset.
• Investors should closely monitor Queensland's state royalty policies, as any fiscal relief could materially alter the reactivation economics for this and other mothballed mines in the region.
• This action underscores the critical importance of jurisdictional risk and cost-curve positioning within the coking coal sector; exposure to assets in high-royalty regions now carries a demonstrated risk of operational suspension.
• Given the strong demand outlook for coking coal, production cuts from high-cost mines like Saraji South could provide price support for the commodity, potentially benefiting lower-cost producers.
