Comments on the geologic information

  • Geologic Description = This area contains significant uranium-rare earth mineralization. ?There are numerous uranium prospects, uraniferous springs and stream-sediments in the area (Barker and Clautice, 1977). Mt. Prindle pluton is a tourmaline- and topaz-bearing porphyritic biotite granite that crops out over a 50-square-km area. Country rock is quartzite and micaceous quartzite with subordinate quartz-mica schist, phyllitic schist and calcareous schist, thermally metamorphosed to upper hornblende facies near the pluton contact. The pluton is cut by 3 major NE-trending faults, and several quartz porphyry, aplite and pegmatite dikes.? Fissure veins containing allanite, bastnaesite, monazite, thorianite, thorite, uraninite, and xenotime occur in Cretaceous porphyritic biotite syenite and alkali granite. The deposit contains significant La, Cd, Nd, Pr, Yd, and fluorite. Hematitic alteration of wall rock and leaching of magnetite occurs in host rocks. Samples contain up to 0.1 percent U-308 and 15 percent rare-earth elements (Burton, 1981).? Some exploration and limited drilling was carried out on Little Champion Creek, but no further development has taken place. Claims were active from 1977 through at least 1981 (Menzie and others, 1983, p. 56).
