Location: This occurrence is on the northwest side of a small ridge that separates the terminus of Concordia Glacier from that of Northland Glacier. This occurrence is in the NW1/4 section 23, T. 7 N., R. 4 E., of the Seward Meridian. This is location S-182 of Jansons and others (1984). It is accurate to within half a mile.
Geology: This occurrence consists of a series of en echelon quartz veins and vein stockworks hosted in Upper Cretaceous Valdez Group slate and sandstone (Nelson and others, 1985). These veins are spatially associated with the Port Wells fault and are similar to those at the Lansing mine (SR073) (Jansons and others, 1984). The veins consist of vuggy quartz containing as much as 15 percent sulfides, chiefly pyrite, chalcopyrite, and pyrrhotite. The veins strike N15 to 40W and dip nearly vertically. This occurrence was discovered in 1981 by the U.S. Bureau of Mines (Jansons and others, 1984). Grab samples contained traces of gold and silver, along with minor amounts of base metals.
Workings: The occurrence was discovered in 1981 by the U.S. Bureau of Mines (Jansons and others, 1984). Their grab samples contained traces of gold and silver, along with minor amounts of base metals.
Age: Oligocene or younger; the veins are associated with the Port Wells fault system, which in nearby areas cut Oligocene granitic rocks.
