Comments on the geologic information

  • Geologic Description = The Whalen mine is part of the Nixon Fork mine complex and descriptions closely follow those of the Nixon Fork mine (MD062). Highly oxidized ore consists of limonite, malachite, Cu-oxides, free gold with minor unoxidized pyrite and chalcopyrite; also minor amounts of scheelite, native bismuth and radioactive minerals are present. Oxidation is pervasive; deposit is in limestone inlier associated with a roof pendant, surrounded by quartz monzonite. Copper content was estimated at between 1 and 2 percent (Brown, 1926). Gold fineness was 812 gold and 171 silver (Smith, 1931). Age is Late Cretaceous, based on isotopic age of monzonite (Moll and others, 1981).
  • Age = Late Cretaceous, based on isotopic age of monzonite (Moll and others, 1981).

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name McGrath

Comments on the production information

  • Production Notes = Production was lumped with Nixon Fork figures (MD062), and has not produced ore during current activities from1995 to 1998.

Comments on the workings information

  • Workings / Exploration = The Whalen mine extended to a depth of 200 ft (61 m) through an inclined shaft and several drifts. The upper part of the workings caved in 1924, and formed a distinctive 200 foot by 100 foot (61 m by 30 m) glory hole (labeled 'glory hole' on USGS topographic maps). The ore that was mined was estimated to contain up to 3.38 ounces/ton (115 grams/tonne) gold.
