Comments on the geologic information

  • Geologic Description = The Galena mine is largely covered by surficial deposits, inferred to be mainly lateral moraine from a more extensive Reid Glacier (Rossman, 1959, B 1058-B, pl. 4). It is within the part of the Reid Inlet gold area or district that is underlain by granodiorite of Cretaceous age. The prospect was completely sloughed when MacKevett and others (1971) searched for it. Twenhofel and others (1949) described the Galena deposit as a banded and vuggy quartz vein between 4-18 inches in width that was exposed on strike for 60 feet. The vein contained pyrite, sphalerite, and galena, and locally native gold.
  • Age = Late Cretaceous or younger.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Juneau

Comments on the production information

  • Production Notes = Thirty tons of ore--reported by Twenhofel and others (1949) who visited prospect in 1940.

Comments on the reserve resource information

  • Reserves = Unknown.

Comments on the workings information

  • Workings / Exploration = Surface workings only. The vein was discovered and located in 1937 by Joe Ibach. Reed (1938) collected a one-foot sample that assayed 0.16 ounce per ton gold, 0.30 ounce per ton silver and 0.79 percent zinc. About 30 tons of ore reportedly was mined by Ibach and Tom Smith in 1939 (Twenhofel and others, 1949, p. 31). The ore had a value of about $60 per ton (about 1.7 ounces of gold per ton).
