|Location and accuracy||This occurrence is located approximately 2 miles west-northwest of VABM Kluklaklatna (spelled Kluklakatna on Nulato 1:250,000-scale quadrangle map), in the southern Kaiyuh Mountains. It is in the NW1/4 sec. 36, T. 14 S., R. 4 E., Kateel River Meridian. The location is accurate within 5 miles.|
This float occurrence consists of limonitic quartz and tourmaline veins in schist, enclosed in pyrrhotite-andalusite hornfels near the Khotol Pluton. The veins(?) also contain sparse, large euhedral crystals of scheelite. Nine rock samples contained up to 238 ppm copper, 45 ppb gold, and 315 ppm tungsten (Flanigan, 1998). Flanigan interprets this gossan to be related to magmatic fluids from the Khotol pluton, based on its proximity to the Khotol pluton and to its low molybdenum content. The Khotol pluton has been dated at approximately 110 Ma by K/Ar and Ar/Ar methods (Flanigan, 1998).Also see NL012, NL014-016, and NL019-022.
