The Lone Tree Gulch is a copper 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 = Late Cretaceous or younger; host is Tertiary to Late Cretaceous tonalite.
Comment (Reference): Primary Reference = Jasper, 1967
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Jasper (1967) reports scattered occurrences of copper mineralization, most likely copper stain, in Tertiary to Late Cretaceous tonalite. There is no visible continuity between occurrences.
Comment (Workings): Workings / Exploration = Lack of continuity for appreciable distances has discouraged prospectors (Jasper, 1967).
Comment (Production): Production Notes = No production.
Comment (Geology): Age = Host rock is Tertiay - Late Cretaceous.
