Wilkie Creek coal mine, U.S. firm Peabody Energy Corp.'s asset in Australia, is being eyed for possible acquisition by South Korea's LG International.

Reuters News reported LG International has actually made a bid on the coal mine asset last April, quoting an unidentified LG International spokesperson. It is not clear, however, if it was a solo bid or submitted via a consortium.

The Queensland mine could be worth anything between $500 million and $750 million, South Korean media reported last April.

Earlier this year, Peabody Energy Corp. employed UBS to scout a potential buyer for the Wilkie Creek coal mine project, The Australian reported. The mine, which lies outside Peabody Energy Corp.'s central operations in the Bowen Basin, has a yearly 2 million tonnes output capacity of thermal coal.
