Location: This unnamed occurrence is at an elevation of about 1,600 feet near the divide between Yankee (ID037) and Ganes creeks (ID011), north of the head of Six Gulch. It is about 0.2 mile north of hill 2024 and 0.4 mile north-northwest of the center of section 15, T. 33N., R. 38W., Seward Meridian. The location is accurate.
Geology: This occurrence consists of gold-arsenopyrite-quartz veins in a quartz-feldspar porphyry dike. The dike intrudes shale and sandstone of the Upper Cretaceous Kuskokwim Group (Miller and Bundtzen, 1994). This occurrence is within 100 meters of the Ganes-Yankee Creek fault zone (Bundtzen and Laird, 1983; Miller and Bundtzen, 1994). A grab sample contained 280 parts per billion gold (Bundtzen and Laird, 1983).
Workings: The mineralized dike was explored by a pit dug before 1979 (Bundtzen and Laird, 1983). Placer Dome Exploration trenched and drilled near the prospect in 1997; the results of that work have not been published.
Commodities (Major) - Au; (Minor) - As
Development Status: None
Deposit Model: Polymetallic vein or Porphyry Au-Cu (Cox and Singer, 1986; models 22c or 20c).
