China's Yanzhou Coal Mining Company Ltd on Tuesday offered to purchase the 22 percent of Yancoal Australia Ltd it does not already own in a deal valued at A$905 million ($825.95 million).

Yanzhou would take the company private if the A$0.91 per share offer, which is a 30 percent premium to Yancoal's closing share price on Monday, is successful.

Yancoal was listed on the Australian stock exchange in June 2012 after a merger with Australia's Gloucester Coal.
