Location: This occurrence, informally called 'Dee's Warm Springs,' is near the warm springs on the southern end of locally-named 'Camp Ridge,' a relatively level, north-south hill west of lower California Creek. For this record, the site is plotted 0.4 mile due north of the center of sec. 14, T. 17 S., R. 5 E., Kateel River Meridian. The location is accurate within 2 miles.
Geology: This occurrence is at a warm springs and consists of ferricrete, iron-stained travertine, and graphitic quartzite float (Flanigan, 1998). The temperature of the springs is about 30 degrees C. Samples of silt from the spring are anomalous in lead, zinc, silver, gold, and arsenic. Iron-stained rocks and gossan float nearby contain up to 725 ppm lead, 550 ppm zinc, 1.8 ppm silver, 45 ppb gold, and 45 ppm tungsten.
Workings: This occurrence was discovered by Anaconda Minerals Company in 1980 (Flanigan, 1998).
Age: Flanigan (1998) interprets this occurrence to be related to magmatic fluids from the Khotol pluton, based on its proximity to the pluton and its low molybdenum content . K-Ar and Ar/Ar dates for the Khotol pluton are approximately 110 Ma (Flanigan, 1998).
Commodities (Major) - Ag, Pb, Zn; (Minor) - As, Au, W
Development Status: None
Deposit Model: Pb and Zn at a warm springs probably related to a nearby pluton
