| Description |
Rock samples were crushed with a Terminator jaw crusher with chrome steel alloy plates so that at least 70 percent of the material passed through a -10 (2 mm) mesh screen. Representative aliquots of 250 grams and 30 grams each were taken using a stainless steel riffle splitter. 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. Most trace-element analyses were performed on the 250 gram split while gold analyses were performed on the 30 gram representative split. 34 samples were analyzed for major and minor oxides, and trace elements using X-ray Fluorescence Spectroscopy following a lithium metaborate fusion. Analysis of trace elements (Nb, Rb, Sr, Y, and Zr) were performed using wavelength-dispersive X-ray fluorescence spectrometry on pressed pellets. |
