Geology and Mineral Occurrences

Historical information has been thoroughly reviewed. Based on this information, as well as Ucore’s own exploration results, more than 30 uranium occurrences have been identified at Bokan Mountain. They are related to a peralkaline ring dike complex known as the Bokan Intrusive Complex. Variable concentrations of light and heavy rare earth elements (REE), zirconium, beryllium, tantalum, and niobium are associated with the uranium mineralization. Most of the uranium mineralization in the area is characterized by multiple, steeply dipping, uraniferous quartz-pegmatite veins localized by radial fractures near the margin of the Complex. The most significant of these more than 30 mineralized occurrences include the Ross Adams, I&L, Dotson Shear, Sunday Lake, and Geiger Zones.
