Simonton & Mills

The Simonton & Mills is a lead, copper, 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 (Exploration): Status = Inactive

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

Comment (Reference): Primary Reference = Johnson, 1914

Comment (Workings): Workings / Exploration = Surface stripping was the only development at the time of the visit of Johnson (1914). Jansons and others (1984) report traces of gold and up to .0.25 oz/ton Ag found in the three samples that were taken. Low mineral development potential.

Comment (Geology): Geologic Description = North striking quartz veins found in Late Cretaceous Valdez Group graywacke and slate. The vein, 6 to 69 inches thick, can be traced for 200 ft and contains gold, galena, pyrite, and chalcopyrite. The primary vein is intersected by another quartz vein, approximately 4 ft thick (Johnson, 1914). Jansons and others (1984) reported traces of gold and up to 0.25 oz/ton Ag in samples.

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

Comment (Geology): Age = Late Cretaceous or younger; veins cut Late Cretaceous Valdez Group graywackes and slates.
