Location: This occurrence is located on a northwest-facing spur overlooking an unnamed eastern tributary of Timber Creek. The occurrence is at an elevation of about 1,100 feet, about 0.3 mile south-southwest of the center of sec. 28, T. 12 N., R54 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence is adjacent to a dike swarm that intrudes the the Mesozoic Gemuk Group that here consists of tan, volcaniclastic sandstone with pebble conglomerate and minor limestone clasts (Cady and others, 1955). The occurrence consists of an irregular zone of axinite-quartz breccia that can be found as rubble crop over an area of about 150 by 100 feet in size. Brown to purple axinite grains and masses up to 2 inches thick make up to 10 percent of the breccia. One sample contained 1.20 percent manganese, 320 parts per million (ppm) zinc, and 310 ppm vanadium (T.K. Bundtzen, unpublished data, 1993).
Workings: The prospect was discovered during surface sampling and mapping by government geologists (T.K. Bundtzen, unpublished data, 1993).
Alteration: Development of axinite-quartz greisen.
Commodities (Major) - V, Zn; (Minor) - Mn
