Jan 25, 2011 (A Wilson) - The pegmatite dike is crudely zone from plagioclase+/- biotite at the margin, to pure quartz at the core. Magnetite and a small amount of pyrite were observed in material from the dump. Grab samples collected by J. McAuley returned an average normalized SiO2 value of 99.96% by XRF analysis. All four samples attain the specifications required for silicon metal based on the XRF analyses.
