|Location and accuracy||This occurrence is on the south tributary to Slatka Creek and north of Kuskulana Pass (MacKevett and others, 1978). It is at an elevation of about 4,200 feet, 2,300 feet northwest of elevation 5075 and 4,000 feet north-northwest of Kuskulana Pass. The site is in the SW1/4 of section 32, T. 3 S., R. 10 E. of the Copper River Meridian. This is locality 35 of MacKevett and others (1978) and locality 121 of MacKevett (1976). The location is accurate to within about 100 feet.|
Geologic descriptionThis occurrence consists of an iron-rich skarn (assumed to be magnetite-rich and to contain disseminated chalcopyrite) that is developed in Triassic marble adjacent to a small Jurassic granodiorite pluton (MacKevett and others, 1978; MacKevett, 1976). A sample of the skarn contained 0.06 parts per million (ppm) gold, 1,500 ppm copper, 7 ppm molybdenum, and more than 20 percent iron (MacKevett, 1976).
