|Location and accuracy||This occurrence is located about 6 miles southeast of Mathews Dome and 2 miles northeast of the junction of Jay and Rye Creeks. The occurrence is at an elevation of about 4,000 feet, at about the center of section 14, T. 30 N., R. 17 W., of the Fairbanks Meridian. The location is accurate.|
Geologic descriptionThis occurrence consists of sulfide-bearing greenschist. Dillon and others (1981, sample 477 [AOF 133B]) collected a rock sample of fine-grained greenschist containing disseminated chalcopyrite and possibly tetrahedrite. The sample contains 11.0 ppm silver, 1,360 ppm copper, and 320 ppm molybdenum. A rubble sample collected by the Bureau of Land Management at this location consists of greenschist with disseminated chalcopyrite and magnetite, but no tetrahedrite (Kurtak and others, 1999, Plate 1, Map no. 93). They also collected an outcrop sample of quartz-chlorite-magnetite schist. Analyses of these samples shows no valuable metals.
