Oleg Novachuk, Chief Executive of Kazakhmys PLC, said: “Against a weak economic backdrop, the copper market again proved resilient in 2012, reflecting its attractive demand and supply fundamentals. In 2013 we anticipate producing a similar volume of copper to 2012, but our operations must be more efficient in order to offset the inflationary trend in costs, and we must also see further progress in health and safety. Our value accretive growth projects continue to make good progress, and as they move towards production we look towards a transformed group, dominated by large, lower cost, open pit mines. I look forward to reporting on our progress through the year.”
