| Description |
200 soil samples were collected across a grid of sample stations. Samples were taken from depths of 6-8 inches within frost boils or residual mineral soil. These samples were then dried and screened at minus-80 mesh, then the undersize was pulverized. Soil samples were analyzed for concentrations of Ag and Au using inductively-coupled plasma techniques following fire assay concentration, for concentrations of Mo, Nb, and Pb using inductively-coupled plasma, for concentrations of Sn using atomic absorption techniques and for concentrations of W using colorimetric techniques. |
