Description 50 rock samples were crushed so that at least 70 percent of the material passed through a -10 (2 mm) mesh screen. These samples were then pulverized in a chrome steel ring mill so that 85 percent of the sample passed through a -200 (75 micron) mesh screen. 50 rock samples were analyzed for gold, platinum, and palladium on a 30-gram representative sample split using Inductively Coupled Plasma - Mass Spectroscopy following Fire Assay Fusion. 50 rock samples were analyzed for trace element geochemical analyses using Inductively Coupled Plasma - Atomic Emission Spectroscopy after HCl:HNO3 (3:1) acid digestion. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for certain elements.
