The Stampede is a silver and gold mine located in Alaska.
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.
Mine Info
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.

Comments
Comment (Geology): Age = Cretaceous or younger based on the age of the quartz diorite to granodiorite that hosts the veins (MacKevett and others, 1974).
Comment (Workings): Workings / Exploration = The Alaska Juneau Gold Mining Company explored the claims and dropped their option in 1929 due to, 'unsatisfactory results' (Eakin, 1918).
Comment (Reference): Primary Reference = Eakin, 1918
Comment (Geology): Geologic Description = This prospect consists of gold quartz veins in a granitic country rock about 300 feet above its contact with limestone. The lower and apparently richest vein varies from 1 to 4 feet in width and is traceable for 2,000 feet along strike. Assays are reported to have been from a few dollars to $70 per ton in gold (up to about 3.5 ounces per ton). The best values were from the narrower portions of the vein and most samples contained a few ounces of silver per ton (Eakin, 1918; 1919). The veins must be younger that the Cretaceous quartz diorite to granodiorite which they cut (MacKevett and others, 1974).
Comment (Deposit): Model Name = Auriferous quartz vein (Cox and Singer, 1986; models 22c or 36a).
Comment (Deposit): Other Comments = This is the northwesternmost auriferous quartz vein occurrence within the zone of lode mineralization that appears to have been the source for the gold placers in the Porcupine area that includes Porcupine Creek (SK041), McKinley Creek (SK045), Cahoon Creek (SK044), and Glacier Creek (SK065).
Comment (Exploration): Status = Probably inactive
