The 85,000 mt of drilling this year should provide enough information to start a concept study, which will lead into a pre-feasibility study, he said. "At the end of this year we should have a global resource," he added. Xstrata said in its annual earnings release that substantial volumes of high grade skarn-style copper mineralization at Las Bambas as well as notable grades of molybdenum and gold mineralization "confirm the potential scale and quality of this mineral district." In addition, Xstrata confirmed a resource of 470 million mt at 0.7% copper at the Antapaccay deposit, located 12 km southwest of the Tintaya copper mine it operates in southern Peru. The estimated resource was calculated by international mining consulting company AMEC, based on drilling done by Tintaya's previous owner BHP Billiton, Luethe said. Xstrata will drill 48,000 mt this year at Antapaccay, Luethe said, which will lead into a pre-feasibility study. --Mary Powers, newsdesk@platts.com For more news, request a free trial to Platts Metals Week at http://www.platts.com/Request%20More%20Information
