Despite the wide-scale exploration currently performed by ALROSA and a significant number of new kimberlite pipes recently discovered in the Yakutian diamond province, mining of the newly discovered diamond deposits is handicapped by a number of factors, including significant remoteness of the newly discovered deposits from the existing infrastructure, severe climate, complicated geological structure of ore bodies, as well as the necessity to carry out extensive development processes using new mining methods and kimberlite...
