Economic information

Comments on the geologic information

  • The schist on the property contains kyanite and sillimanite in patches enclosed by the vermiculite. The vermiculite schist was also reported to contain a few specks of corundum. Based on similar corundum occurrences reported elsewhere in wyoming, there is a possibility for ruby or sapphire here. (Bull. 71, p. 27).

Comments on the ownership information

  • "This deposit was foremerly owned by the Mikolite Company" (Bull. 50, p. 234). Assuming the site is named Union Asbestos and Rubber Co., it is likely that they were the current owner as of 1966.

    Material hand-sorted vermiculite
    Ore mined 907mt
    Accuracy Accurate

Comments on the production information

  • "The property was mined for vermiculite between 1937 and 1941, and three shafts, a drift, and a number of propect pits were dug." (WGS, 2000, p. 27) "...produced 1000 tons of hand-sorted vermiculite from 1937-1941" (Bull. 50, p. 234).

Workings at the site

  • Type of workings Underground
    Name of workings 3 shafts, a drift, and several pits.

Comments on the workings information

  • One shaft was sunk to a depth of 65 ft and was connected to a 95-ft-deep shaft farther up the hill by a 112-ft-long drift driven between the shafts. A third shaft on top of the hill was sunk to a depth of 105 ft.
