Samples were assayed for gold by inductively coupled plasma-atomic emission spectroscopy following a 30 gram (g) fire assay fusion (FA-ICP-AES). Platinum and palladium were assayed for selected samples by inductively coupled plasma-atomic emission spectroscopy following a 30 g fire assay fusion (FA-ICP-AES). Trace-element analyses were performed by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) methods after four-acid, near-total digestion. This method of digestion is possibly incomplete for Ba, Cr, Ti, and W and may result in lower analytical results for these elements. Rock samples with trace gold and/or copper values above the detection limit in the initial trace element geochemical analysis were reanalyzed for [...]
