Major- and trace-element values for rock samples were determined by ALS Geochemistry method MEMS61: Four-acid digestion followed by inductively-coupled plasma�atomic emission spectrometry (ICPAES) and inductively-coupled plasma�mass spectroscopy (ICP-MS); Au values were analyzed using flux digestion and fire assay and ICP-AES (ALS Geochemistry method Au-ICP21). Samples that exceeded detection limits for elements of interest were reanalyzed using specific elemental tests. Over-limit values for Pb were analyzed using four-acid digestion followed by inductively-coupled plasma�atomic emission spectrometry (ALS Geochemistry method ME-OG62). Selected samples were analyzed for were Pt, Pd, and Au using lead oxide fire assay with ICP-AES finish [...]
