Location: This occurrence is at an elevation of about 2,200 on the northeast ridge of Caribou Mountain, about 2.8 miles northeast of the summit. The location is accurate within one-half mile.
Geology: This occurrence consists of a molybdenite(?)-bearing quartz vein (Miller and Ferrians, 1968). A grab sample of the vein contains 200 ppm molybdenum, 100 ppm lead, and 3,000 ppb bismuth. The rocks in the area are Cretaceous porphyritic monzonite and quartz monzonite. No other information is available. Stream-sediment samples from creeks draining the intrusive contact in this area are anomalous in lead and copper (Miller and Ferrians, 1968).
Workings: Only surface sampling.
Age: The Zane Hills pluton is 81 Ma as dated by K/Ar methods (Miller and others, 1966).
Commodities (Major) - Mo(?); (Minor) - Bi, Pb
Development Status: None
