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 plasma-mass spectroscopy (ICP-MS); Au values were analyzed using flux digestion and fire assay and ICP-AES (ALS Geochemistry method Au-ICP21); Hg values were analyzed by aqua regia digestion followed by ICP-MS (ALS Geochemistry method Hg-MS42). Samples that exceeded detection limits for elements of interest were reanalyzed using specific elemental tests. Over-limit values for Au were analyzed using 30-g fire assay with gravimetric finish (ALS Geochemistry method Au-GRA21). Overlimit values for Ag were analyzed by [...]
