V. B. Yadav,Vandana Pulhani,S. K. JhaThere are thousands of new prospects in the process of exploration and resource proving, and some of them will likely turn out to be “giant”. In addition to this, some existing “l(fā)arge” deposits or districts will achieve the “giant” rank as a result of ongoing exploration and cut-off grade lowering.
