Huge Robert FriedlandIn January 2013, a new independent mineral resource estimate was prepared for the Kamoa Copper Discovery by AMEC E&C Services of Reno, Nevada. The new estimate ranks Kamoa as Africa's largest high-grade copper discovery and the world's largest undeveloped high-grade copper discovery. As of January 2013, Ivanplats had discovered Indicated Mineral Resources of 739 million tonnes grading 2.67% copper, containing 43.5 billion pounds of copper, and Inferred Mineral Resources of 227 million tonnes grading 1.96% copper, containing 9.8 billion pounds of copper. A 1% copper cut-off grade and a minimum vertical mining thickness of three metres was applied in each classification.
