Summary

Samples were analyzed for gold by fire assay pre-concentration of a 30 gram sample followed by an AA finish with results reported in parts per billion. For gold values exceeding the upper detection limit of 10,000 ppb, a gravimetric finish was performed and results reported in ounces per ton. Silver, copper, lead, zinc, and molybdenum were analyzed by both AA and ICP techniques with results reported in parts per million. The result from the more accurate method is presented. Those that exceeded the upper detection limits were subjected to low level assays with results reported in percent, with the exception ofsilver which was finished with a gravimetric method and results reported in ounces per ton. Platinum and palladium were analyzed [...]
