(Reuters) -Global miner BHP Group Ltd signed a deal on Monday to sell its stake in BHP Mitsui Coal (BMC), a metallurgical coal joint venture in Queensland, to Stanmore Resources Ltd for up to $1.35 billion, the companies said.

Stanmore, which is majority-owned by Singapore-listed Golden Energy and Resources Ltd, agreed to acquire BHP’s 80% stake in BHP Mitsui Coal, which owns and operates two open-cut metallurgical coal mines in the Bowen Basin.

“It’s a fair to good price from the (seller’s) perspective,” said analyst Peter O’Connor of Shaw & Partners in Sydney.

The remaining stake in BHP Mitsui Coal is owned by Japan’s Mitsui & Co Ltd.

Stanmore will pay $1.1 billion on completion of the sale and an additional $100 million six months after that. There is a potential for up to $150 million in a price-linked earnout, payable in 2024, the companies added.

Stanmore, which has a market capitalisation of $207.1 million, according to data from Eikon, said it intends to fund the acquisition with a $625 million debt facility and a $600 million equity raising. (https://bit.ly/2ZZpgzh)

The deal allows Golden Energy, controlled by Indonesia’s Widjaja family, to diversify beyond thermal coal.

Golden Energy runs a thermal coal mine in Indonesia and a gold mine in Queensland. It will guarantee Stanmore’s obligations and any break fee to up to $600 million.

The deal still needs to go to Australia’s Foreign Investment Review Board for approval. Shares in Stanmore saw their best session in five years, surging as much as 23.7% to A$1.280 ($0.9469). BHP shares rose 1.2%.

Analysts at RBC expect BHP to distribute proceeds from the divestment among shareholders via special dividends on completion in mid 2022, supplementing the miner’s dividend yield by about 0.8-8% in the year ending in June.

BHP will continue to operate BMC until completion and work with Stanmore during the ownership transition, the miner said in a separate statement https://bit.ly/303nXiv.
