The property is in Misty Fiords National Monument Wilderness.
Location: The approximate location of the Pyrite Lode, known only from U.S. Bureau of Mines (1977) claim records, is at an elevation of about 400 feet, 0.4 mile inland from the shoreline of Behm Canal, and about 1.55 miles northeast of Roe Point. The site is in section 27, T. 76 S., R. 95 E., of the Copper River Meridian. It corresponds to loc. 103 in Elliott and others (1978). The location is probably accurate within about 0.2 mile.
Geology: The Pyrite Lode prospect area is underlain by an assemblage of undivided Mesozoic or Paleozoic metamorphosed sedimentary, volcanic, and intrusive rocks; and by a stock and dikes of Cretaceous granodiorite and quartz diorite (Berg and others, 1988, p. 21, 22). The undivided assemblage was regionally metamorphosed to amphibolite grade in middle or Late Cretaceous time, and locally remetamorphosed to hornblende hornfels near the contacts of some of the granodiorite and quartz diorite plutons. The deposit consists of small pockets of molybdenite and pyrite in a quartz fissure vein in metamorphic rocks (Elliott and others, 1978). The Pyrite Lode was staked in 1953 (Maas and others, 1995, p. 266). No other information about this prospect has been made public. Assuming that the vein cuts the foliation of the metamorphic rocks, it probably is younger than the middle or Late Cretaceous regional metamorphism.
