Bo ld values are qualitative only because of low rec overy. Values are certified by Inorganic Ventures INC. at 3x and 10x the approximate instrumental LOD Values reported were obtained with a Spectro Analytical Instruments EOP ICP; perform anc e m ay vary with instrument and should be independently verified.
