The Lagoon Creek is a gold and silver 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 (Reference): Primary Reference = Jansons and others, 1984

Comment (Workings): Workings / Exploration = Development limited to a 15 ft long adit. Jansons and others (1984) reported six samples contained up to 0.005 oz/ton Au and up to 0.05 oz/ton Ag, thus site has low potential for mineral development.

Comment (Deposit): Model Name = Chugach-type low-sulfide Au-quartz veins (Bliss, 1992; model 36a.1 ?) or Epithermal Au vein ?

Comment (Production): Production Notes = No reported production.

Comment (Geology): Geologic Description = According to Jansons and others (1984), quartz veins and stringers up to 1 ft wide are found in a well developed shear zone in hornelsed Late Cretaceous metasedimentary rocks of the Valdez Group. The zone is about 12 ft wide along the contact of a 50 ft felsic dike with the Valdez Group rocks. Disseminated grains and massive pods of pyrite, with lesser arsenopyrite and chalcopyrite present.? Six samples contained up to 0.005 oz/ton Au and up to 0.05 oz/ton Ag (Jansons and others, 1984).

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Late Cretaceous or younger; shear zone cuts metasedimentary rocks of the Late Cretaceous Valdez Group.
