RE Assay
RE AssayIntervals containing visible gold are assayed by fire-assay
procedure for metallics gold. This procedure involves pulverizing a one-kg
sample and passing the prepared pulp through a 150 mesh (106 micron) screen. The
+150 mesh material is analyzed in its entirety by fire assay. The -150 mesh
material is homogenized and a 50-gram subsample is assayed by fire assay with
gravimetric finish. The samples from sections that did not contain visible gold
were fused by fire assay and analyzed by atomic absorption spectroscopy. A
series of standards are routinely introduced with each batch of samples. Quality
controls include preparation and analysis statistics performed to industry
standards
