Location: This occurrence is at an elevation of 1250 feet, about 0.5 mile northwest of the Kanuti River, and just north of the center of the south boundary of section 35, T. 18 N., R. 16 W., of the Fairbanks Meridian. The location is accurate within one-quarter mile.
Geology: This occurrence consists of anomalous U, Sn, Pb, As, Sb, Cu, and Li in altered rhyolite porphyry, biotite granite, and leucocratic granite within the Cretaceous(?), Hot Springs granitic complex (Barker and Foley, 1986). The highest values were in samples of the altered rhyolite porphyry; metazeunerite was identified by X-ray diffraction in one sample (Barker and Foley, 1986). A gray-green weathering rock contains 1,000 ppm uranium, 216 ppm tin, 2,616 ppm lead, and 341 ppm copper. The extent of this mineralization is uncertain due to poor exposures, but similar pieces of mineralized float occur elsewhere in the area. The Hot Springs pluton is composed principally of coarse-grained porphyritic and seriate biotite granite and biotite, quartz monzonite. The granitic rocks are intruded by younger rhyolite porphyry dikes and stocks (Barker and Foley, 1986).
Workings: Only surface sampling. Claims were located in 1980 but there is no indication of further activity.
Age: The Hot Springs pluton is assumed to be Cretaceous because it is similar to isotopically-dated Cretaceous plutons in the region.
Alteration: Published reports indicate that the rocks are altered, but the alteration is not described.
