|Deposit||Model Name = Polymetallic veins|
|Deposit||Other Comments = This prospect, identified in 1972 (Berg and others, 1977, p. 77, 79-80) by three small pits, was called Dugas by Buddington (1929, p. 99) and Stampede by Berg and others (1977, p. 38-39, 77, 79). The Dugas/Stampede prospect area was originally staked in 1925 and restaked several times since then. In 1958 it was covered by the Alaska State Mines Extension group of claims. None of these claims was active in 1973.? the name Blasher Extension has also been associated with this prospect area.? Site appears to be just within Misty Fiords National Monument.|
