The Dun Glen Mine Project is a gold mine located in Pershing county, Nevada at an elevation of 5,217 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Elevation: 5,217 Feet (1,590 Meters)

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.
Dun Glen Mine Project MRDS details
Primary: Dun Glen Mine Project
Secondary: Sierra Placer Gold Deposit
District: Sierra (Dun Glen, Orofino, Chafey, Sunshine) District
Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comment (Economic Factors): Total past production and reserves are unknown.
Comment (Identification): The current record describes an area covered by the Sierra Placer gold deposit described by earlier MRDS record M242417 from which some material has been incorporated into the current new record.
Comment (Location): The placer mining operation is situated near the mouth of Dun Glen Canyon, approximately 8.5 miles northeast of the town of Mill City and four miles east of Interstate 80.
Comment (Workings): The area is covered with numerous shallow surface prospects on the alluvial fan as well as an open pit, new pit, bulldozer work, dams ponding silts (1984)
Comment (Commodity): Ore Materials: free gold
Comment (Commodity): Gangue Materials: gravel
Comment (Deposit): 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.
Comment (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.

Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more at Gold Districts of Nevada.
