    When the mineral seam becomes exposed, it is drilled, fractured and the mineral recovered for processing. Open cut mining can be more effective than underground methods, generally recovering 90% of a mineral deposit, and accounts for about 65% of raw coal production in NSW. Open cut mining is also used for some gold and copper production in NSW.
