Comments on the geologic information

  • Geologic Description = Stibnite is found in small, discontinuous, lenticular bodies in black, slaty schist (Joesting, 1942 [ATDM Pamph. 1, p. 12]). Three tunnels were driven on the prospect, one of which was 90 feet long. About two tons of high-grade stibnite was mined and sacked during prospecting, but there is no mention if any ore was shipped (Joesting, 1942 [ATDM Pamph. 1, p. 12]). A sample taken from the site contained 47percent antimony and traces of gold, silver, and lead.

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Bonnifield

Comments on the production information

  • Production Notes = About two tons of high-grade stibnite was mined and sacked during prospecting, but there is no mention of any ore having been shipped (Joesting, 1942 [ATDM Pamph. 1, p. 12]).

Comments on the workings information

  • Workings / Exploration = Three tunnels were driven on the prospect, one of which was 90 feet long (Joesting, 1942 [ATDM Pamph. 1, p. 12]). In 1994, all the workings were caved, and there is little sign of this prospect other than a few, small pieces of rock that contain stibnite near the caved adits (Donald Grybeck, field observations, 1994).
