|Location and accuracy||This record represents a prospect area, informally called UCC Stratabound, at least partially in sections 26 and 27, T. 7 N., R. 18 W., of the Fairbanks Meridian. For this record, the site is at an elevation of about 1,200 feet on a south tributary of Bear Creek, near the junction of three branches of the tributary, in the southeast quarter of section 27.|
Geologic descriptionThe country rocks in the area of the UCC Stratabound prospect consist of Paleozoic schist (Chapman and others, 1982). A Tertiary or Cretaceous quartz monzonite pluton is exposed approximately 5 miles to the southeast. The prospect was sampled in 1979 by Union Carbide Corporation, who reported up to 10 percent combined pyrite-chalcopyrite-pyrrhotite in quartz- mica schist (North Star Exploration, Inc., 1999 [Report 99-34]). They also reported anomalous gold and silver values in geochemical samples of the sulfide-bearing rocks. After examining their data, the company decided that the deposit was sub-economic at that time (Placer Dome, 1989). Although they reported no lead or zinc values, North Star Exploration, Inc., has classified the prospect as a potential stratabound lead-zinc deposit, due to its proximity to lead-zinc mineralization at Sox-Rainey (TN043) (North Star Exploration, Inc., 1999 [Report 99-34]; North Star Exploration Inc., 2000 [Highly mineralized block 20]).
