Subject: deeper elevations mining. Commissioning of the first phase of the XXX underground mine, with a capacity of 1.5 million tonnes per year, is planned for 2014, and it is envisaged that the mine will reach its full production capacity of 4.0 million tonnes per year by 2017. Further exploitation of the reserves below 380 meters will require additional development to access deeper elevations.В другом разделе:
