The Lundgren-Rowley is a tungsten 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 (Workings): Workings / Exploration = Surface samples were taken in the early 1970's from bedrock exposed by a dozer trench (Conwell, 1972).

Comment (Commodity): Gangue = potassium feldspar

Comment (Reference): Primary Reference = Conwell, 1972

Comment (Deposit): Model Name = Scheelite in quartz diorite.

Comment (Geology): Geologic Description = Samples of quartz diorite with scheelite contained from 0.045 to 0.35% tungsten (Conwell, 1972). Petrographic examination of the quartz diorite identified the following minerals associated with the tungsten ore: quartz, plagioclase, potassium feldspar, biotite, and amphibole. No significant gold or silver was found upon atomic absorption analysis (0.002 to 0.008 ounces of gold per ton; 0.015 to 0.02 ounces of silver per ton) (Conwell, 1972).

Comment (Exploration): Status = Inactive
