Summary

Major- and trace-element values for rock samples were determined by ALS Geochemistry method ME-MS61: Four-acid digestion followed by inductively-coupled plasma-atomic emission spectrometry (ICP-AES) and inductively-coupled plasm-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 Ag, Pb, and S were analyzed using four-acid digestion followed by inductively-coupled plasma-atomic emission spectrometry (ALS Geochemistry method MEOG62), assay with gravimetric finish (ALS Precious Metals method Ag-GRA21), or atomic absorption [...]
