Summary

All samples were analyzed for gold using a 50 g fire assay fusion and either ICP-AES or atomic absorption spectrometry (AAS). Trace-element geochemical analyses were performed by inductively coupled plasma-mass spectrometry (ICP-MS) methods after four-acid, near-total digestion. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for these elements. Samples with greater than 10 percent calcium and showing interference were reanalyzed by ICP-AES. Mercury was analyzed by aqua regia digestion/cold vapor-AAS (detection limits on samples requiring dilutions for mercury analysis were increased according to the dilution factor). Rock samples with trace metal values above the detection [...]
