Ann: CYM:HIGH-GRADE COPPER SURFACE SAMPLES AT THE CUE COPPER PROJ, page-55

Hi Cash. I find it strange that they'd defer to ppm instead of grams per tonne in a mining application? I'd normally associate ppm with volumetric considerations and not so much for calculations of contained metals where the relative density of materials contained in a sample would vary? Do they report ppm values for mining as a percentage of weight, not volume?
