Report: Iron Hill LC007368 Workings are accessed by crossing to the north of the Blackfoot River below the Anaconda mine site and going northeast approximately 1000 feet. Workings include three adits: a totally collapsed adit with a prominent, sulfide-rich dump (at least 300-400 feet from the river), another collapsed adit to the north with a smaller dump (this may or may not be the same property) and a short collapsed adit with a dump in the floodplain near river level with a seep but no real discharge. There was so little water here that it was impossible to sample. A line of prospects trends uphill towards the Skyscraper property from the most prominent adit. A small seep issues from a collapsed adit at the base of a talus at the lower adit but considering the overwhelming influence of the Mike Horse and Anaconda mines on the river, this seep is trivial. No evidence of adverse effects are present; no sample was taken. Commodities at the Iron Hill include lead and zinc (MILS database); assays from a composite sample from the waste dump ran 0.004 opt Au, 0.23 opt Ag, 0.04% Cu, 0.08% Pb and 0.02% Zn. Diorite, FeOx, pyrite, euhedral quartz and clays are found on the largest dump. The Iron Hill is found on HNF land and is mentioned in Pardee and Schrader (1933), Shea (1947), McClernan (1983), and Byer (1987).
