Gujarat NRE FCGL Pty., a unit of India's largest non-state producer of steelmaking coal, agreed to pay A$49 million ($41 million) to buy the Elouera coal mine from BHP Billiton Ltd.
BHP, the world's largest mining company, ceased mining at the mine in Australia's New South Wales state in June 2005, the Melbourne-based company said in an e-mailed statement.
"This won't have any impact on our production volumes," said Emma Meade, a spokeswoman for BHP Billiton, over the phone.
Gujarat NRE Coke Ltd. in April said it plans to sell shares in its Australian unit to fund expansion as demand for coal from Indian steelmakers rises. India's imports of steelmaking, or coking, coal may increase 10 percent this year, according to the country's mining ministry.
