287 samples were analyzed for gold using Atomic Absorption Spectroscopy after Fire Assay Fusion. 287 samples were analyzed for mercury by Cold Vapor Atomic Absorption Spectroscopy after HCl:HNO3 (3:1) acid digestion. All other geochemical analyses on the 30 samples were performed, after HF-HNO3-HClO4 acid digestion with a HCl leach, by either Inductively Coupled Plasma - Atomic Emission Spectroscopy, Inductively Coupled Plasma - Mass Spectroscopy, or a combination of Inductively Coupled Plasma - Atomic Emission Spectroscopy and Inductively Coupled Plasma - Mass Spectroscopy. Results were corrected for spectral interelement interferences. The HF-HNO3-HClO4 acid digestion with a HCl leach method of digestion is possibly incomplete for [...]
