Bulk miningDirectional dill cores will give a much better understanding of the ore body ( technically Not an ore body of yet). Everything depends on grade and width of of the veins/ore body and of course, dilution, orientation of the footwall/hanging wall. Cut and fill/ VBM would be best for a sizable ore body, anybody's guess at this point in time. It is my personal opinion that this will turn out to be a very good investment.....time will tell.
