Eventually you have to factor in the waste rock for the stripping and dilution ratios but right now we need a lot more drilling to define the basic geometry better. The cross-section shows that the mineralization can be as shallow as 25 m in historical hole M17-84 : http://www.usetdas.com/maps/kodiak/KodiakMilestoneCrossSection.pdf

Premier applied an adjustment to account for excavation voids in their resource estimate on the Hardrock project so it can be done prior to an economic analysis. Let's see if Milestone gets to that stage.
