Comments on the workings information

  • Workings consist of an open pit.

Comments on other economic factors

  • Production from 1904 to 1935 was reported as 4,600 cubic yards of ore. Production from 1935 to 1939 was 336,304 short tons grading 0.17 opt Au valued at $1,615,037. Production from1986 to 1987 was 58,000 ounces of gold.
    Reserves were estimated in 1986 to be 200 kilotonnes of ore grading 0.1 opt Au and 0.4 opt Ag.

Comments on development

  • The deposits were first discovered in 1904 by Frank Horton. A few tons of ore were hauled initially but ore zones were small. A 35-ft shaft was sunk and abandoned. In 1927 Horton's son reopened a prospect shaft and took out $150,000 worth of ore. The mine was then intermittently operated until 1934, when the mine was purchased and Weepah Nevada Mining Co was formed to operate it. An open pit mine was developed and worked at 250 tons/day. It was listed as an active open pit silver-gold mine employing 10 persons in 1983. The property was drilled by Pacific Realm in 1984-85, Sunshine Mining Co. leased it in 1986 and began mining it in Sept. 1986, shipping 1000 tpd to its Sixteen-to-One mill, 14 miles away at Silver Peak

    The owner of the property in 1997 was Dia Met Minerals, Ttd.; Goldtex Resources, Ltd. and ongoing exploration activity was reported. Goldtex Resources merged with Cantex Mine Development in 2001. In 2001 Dia Met did not list the Weepah as one of its properties.
