The Bridger Mine is a silver, lead, and gold mine located in Carbon county, Wyoming at an elevation of 8,638 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.

Satelite View
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.

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.

Analytical Data
Analytical Data: Assays range from a trace to 69 opt Au. Gold values are greater near the surface, silver values increase with depth. A 100 lb. sample representing the average of the streak is reported to have assayed 90 oz silver and $5 gold per ton (0.26 opt) (as of 1904).

Comments
Comment (Deposit): Hanging wall = Au trace to 69 oz/ton; Middle silicified qtzite = Ag 90 oz/ton; & Au 0.26 oz/ton; Spencer, 1904, p.100. Au 111 ppb; Ag 200 ppm; Cu 2089 ppm; Pb 1497 ppm; Zn 602 ppm; Ni 16 ppm; Sutherland and Hausel, 1999 unpublished field notes.
Comment (Deposit): In Sept. 2008, the main shaft on the Wicked Slope claim was caved and enclosed in a falling down log structure. All the dump material had been used by the Sinteks and their neighbor as driveway fill.
Comment (Deposit): Site visited in Sept. 2008 by Anna Wilson and Bill Heran, USGS. The owners for the previous 20 to 30 years, Jack and Dorothy Sintek (from Saratoga, WY) showed us around the property.
Comment (Deposit): Terry Klein's updates appear not to have been entered into newMRDS. 0.5-4 ft wide sulfide- & calcite-bearing qtz vein in qtzite; altered zones (6"-3' wide) in both hanging- and foot-wall; Au decreases & Ag increases with depth. Vein enclosed by narrow alteration zone. Vein conformable to regional foliation trending NW, dip 25 - 55 degrees SW. Highly mineralized silicification 10 in wide on hanging wall, 4 - 10 in wide on footwall. mine lies near qtzite contact with overlying metagabbro.
Comment (Deposit): Terry Klein (USGS) also references Sutherland and Hausel, 1999, unpublished field notes.
Comment (Deposit): Shaft located and labeled on 1:24K USGS topo, described by Spencer (1904)
Comment (Deposit): Vein conformable to regional foliation trending NW, dip 25 - 55 degrees SW
Comment (Deposit): Vein trends NW, dips 25 to 55SW. Mineralized zone is 1 to 4 ft. wide. Quartz vein is 0.5 to 3 ft. wide.
