Stream sediment samples were analyzed for a suite of elements using atomic absorption methods. Rock samples were analyzed for concentrations of Ag, As, Co, Cu, Ni, and Zn by atomic absorption. In cases where Cu concentration exceeded 20,000 ppm, reanalysis was performed by wet chemistry. All samples were analyzed for Au, Pd, and Pt using inductively-coupled plasma following fire assay by U.S. Bureau of Mines Reno Research Center.
