  • Total past production and reserves are unknown.

Comments on development

  • The Sierra District placers were among the most productive in the state withan estimated $4 million in production before 1900, mostly by Chinese miners working first in Auburn and Barber Canyons, and later in Rockhill Canyon. There were some intermittent 20th century small-scale operations mostly in the 1930s and 1940s.
    The Dun Glen placer was listed as an active open pit gold mine in 1983, operated by Proquip, Inc., employing 16 persons. It was still active in 1984-1985. In March, 1985, it was reported that Homestake Mining Co. had signed an option to enter a joint venture with Proquip. The placer continued to be intermittently active to the present. Tahoe Milling, Inc., operators of the facility, known as the Dun Glen Mine Project, applied in 2003 for renewal of a Water Pollution Control Permit for the mine.
    The project consists of a physical separation facility with an estimated maximum production rate of 1,400,000 cubic yards per year. Gold is extracted from the Dun Glen Creek gravels and adjacent terrace placer deposits using a mobile placer plant that operates within the active creek channel. No chemicals are approved for use in the gold recovery process and make-up water, derived from Dun Glen Creek, is recycled. Facilities are required to be designed, constructed, operated and closed without any discharge or release in excess of those standards established in regulation except for meteorological events which exceed the design storm event. In May 2003, Vector Mining, Inc. applied to NDEP for a Reclamation Permit for the Dun Glen Mine.
