trace element analysis of rock sample 2006MBW163A


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 [...]
