Whole-rock major oxide analyses were performed by using atomic absorption by Bondar-Clegg. An unknown laboratory performed trace element analysis for cobalt, copper, nickel, and lead by atomic absorption. Gold, silver, cobalt, chromium, copper, and nickel content was determined by atomic absorption with results reported in ppm. The samples were preconcentrated by fire assay before being analyzed for gold, platinum, palladium, iridium, osmium, rhodium, ruthenium by inductively coupled plasma.
