BHP Billiton has approved development of the Caval Ridge mine project as well as an expansion of the Peak Downs mine in the northern Bowen Basin in Central Queensland, Australia. The initial project will add 8 Mt/y capacity (100% basis) in export metallurgical coal, with the expectation of a rapid, low cost expansion to 10 Mt/y.
