Feb 20, 2009 (A Wilson) - Mineralization consists of alkalic feldspar, quartz, minor muscovite, biotite, Fe-Ti oxides and erratically distributed markedly radioactive euxenite-polycrase. The euxenite-polycrase forms massive aggregates up to 15 cm across, concentrated near the footwall of the dike. Quartz is most abundant near the core and forms irregularly distributed pods throughout the dike. Grab samples collected from the site returned 8.37% U3O2
