Location: This occurrence, informally called the Kaiyuh Ridge gossan, is in the southern Kaiyuh Mountains. It is at an elevation of about 2500 feet, 0.9 mile due west of VABM Kalyuh Hill. VABM Kalyuh Hill is approximately 5 miles south-southwest of the summit of Khotol Mountain. The location is accurate within 2 miles.
Geology: This occurrence is a weakly mineralized limonite gossan in garnet-chlorite-quartz schist and quartz-amphibole schist. The gossan occurs along a north-south-trending shear zone. Samples contain up to 10.0 ppm silver and 550 ppm lead (Flanigan, 1998). Also see NL012-016 and NL020-022.
Workings: This occurrence was discovered by Anaconda Minerals Company in 1980 (Flanigan, 1998).
Age: Flanigan (1998) interprets this gossan 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).
