Location: This occurrence is at an elevation of about 1,400 feet, on the southwest flank of the ridge between Orum and Wolverine creeks. The site is at Alaska Division of Geological and Geophysical Surveys (ADGGS) sample station 97KC023 (Liss and others, 1998), about 0.2 mile east-southeast of the center of section 32, T. 5 N., R. 15 W., of the Fairbanks Meridian. The location is accurate within 500 feet.
Geology: Bedrock in the Orum-Wolverine creeks area consists of Triassic to Permian argillite, sandstone, and shale (Reifenstuhl and others, 1998). These rocks are in thrust-fault contact with Jurassic or Cretaceous metasedimentary rocks to the south, and with lower Paleozoic or older chert, cherty argillite, siliceous dolostone, and calcareous mudstone to the north. The Cretaceous monzodiorite, syenite, and monzonite Roughtop Mountain pluton crops out about 1.5 miles to the south (Reifenstuhl and others, 1998). A sample (97KC023) of quartzite on a ridge south of Orum Creek contained 306 parts per million (ppm) copper, 7.81 percent iron, 1,170 ppm phosphorous, and 944 ppm zinc (Liss and others, 1998). There is no record of exploration or mining at this site.
Workings: A sample (97RN035) of a quartz vein at the contact between quartzite and argillite on the ridge between Minook and Eureka creeks contained 360 parts per million (ppm) arsenic (Liss and others, 1998). There is no record of exploration or mining at this site.
