Initially, all samples were assayed for gold by Atomic Absorption Spectroscopy following a fire assay fusion. Samples containing greater than 10,000 ppb gold were also assayed by Gravimetric finish following a fire assay fusion. All samples were assayed for mercury by Inductively Coupled Plasma - Atomic Emission Spectroscopy after Aqua Regia digestion and by Atomic Absorption Spectroscopy after Aqua Regia digestion/Cold Vapor. High-grade copper samples were assayed by AAS. All other trace element geochemical analyses were performed by Inductively Coupled Plasma - Atomic Emission Spectroscopy methods following Aqua Regia digestion. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for certain elements. See publication for a listing of these elements.
