Reference information

Comments Ussoltsev (2011) estimated geological resource of 1,169 Mt of ore at a copper grade of 0.36%, a gold grade of 0.21 g/t, a silver grade of 4.9 g/t and molybdenum and rhenium by-products. Mine is under construction, with production expected by 2015. Resource includes (Singer and others, 2008); 0.59–1.04 g/t Pt, 0.28–0.37 g/t Pd in concentrate; 230–1,500 ppm (average 882 ppm) Re in Mo; Re will be produced. Deposit is exposed. Main ore-related intrusion is a porphyryitic tonalite that is the final representative of a suite of dioritic, quartz dioritic and tonalitic rocks.
