He says the company will consider greenfield exploration, which is the development of new mines, once the market improves. "We are a bit concerned with developing new greenfields because of the massive capital costs and overruns which have been part of the greenfields projects in Australia and other parts of the world. "When commodity prices pick up I can assure you we will be opening new mines in Australia, we have just got to find the right reserve and we will be developing that."
