Summary

Whole rock analysis for major and minor oxides was performed by fusing with a lithium borate flux to create a disk for X-ray fluorescence or further dissolved into solution for inductively coupled plasma. Rock, soil, and stream sediment samples were analyzed for a standard suite of 36 elements. Pan, placer, and sluice concentrates were also analyzed for platinum, palladiaum, and (when warranted) uranium, and thorium. Gold, platinum, and palladium were preconcentrated by fire assay with gold being followed by either an atomic absorption (AA) finish or ICP atomic emission spectrospcopy finish, and platinum and palladium followed by an ICP finish. Occasionally, a sample was analyzed for gold multiple times with erratic results and thus [...]
