BHP has sold its stake in a metallurgical coal joint venture in Queensland.

Stanmore Resources has agreed to buy BHP's 80 per cent stake in BHP Mitsui Coal (BMC) for more than $1.6 billion.

BMC owns and operates the Poitrel and South Walker Creek mines in central Queensland's Bowen Basin.

“As the world decarbonises, BHP is sharpening its focus on producing higher quality metallurgical coal sought after by global steelmakers to help increase efficiency and lower emissions,” BHP's Minerals Australia president Edgar Basto said in a statement.

“Under this agreement, BMC will transition to Stanmore Resources, an ASX-listed company that has established relationships with traditional owners and strong engagement with their workforce and local communities.”

BHP will run BMC until the sale is complete in mid-2022, and has agreed to provide “transitional services” to Stanmore.

Meanwhile, BHP is also looking to sell its open-cut thermal coal mine at Mt Arthur in the NSW Hunter Valley.

“BHP remains open to all options and continues consultation with relevant stakeholders,” Mr Basto said.
