Location: The location is the approximate location of placer claims active in 1976 to 1979. Hot Springs Creek originates southwest of Circle Hot Springs and flows just north of town where it empties into a marsh.
Geology: The headwaters of Hot Springs Creek drain an area underlain by Tertiary granite. The granite is light gray biotite-hornblende-tourmaline monzogranite to syenogranite (Wiltse and others, 1995). Uranium- and/or thorium-bearing allanite, sphene and zircon, and scheelite were found in placer concentrate samples (Cobb, 1976, [OFR 76-633]). Houston International reportedly tested sedimentary uranium in Tertiary sediments near Circle Hot Springs in 1980. This site is a U/Th-W-REE geochemical anomaly.
