Summary

123 samples were analyzed for gold on a 30 gram representative split using Atomic Absorption Spectroscopy after Fire Assay Fusion. 2 samples with greater thatn 1000 ppb gold were analyzed using Gravimetric methods after Fire Assay Fusion. 62 samples containing greater than 15 ppb gold were analyzed for mercury by Cold Vapor Atomic Absorption Spectroscopy after HCl:HNO3 (3:1) acid digestion. 124 samples were analyzed using Inductively Coupled Plasma - Atomic Emission Spectroscopy after HF-HNO3-HClO4 acid digestion with an HCl leach. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for these elements.
