The Louise is a 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 (Deposit): Model Name = Polymetallic veins? (Cox and Singer, 1986; model 22c)

Comment (Geology): Geologic Description = The Louise prospect is about 1,500 feet northwest of the Owhat prospect (RM016). According to Bundtzen and Laird (1991), it was first reported by Holzheimer (1926) as a 1,000-foot-long gold-arsenic deposit. Bundtzen and Laird (1991) described the deposit as an arsenopyrite, chalcopyrite, quartz, and black tourmaline vein that trends northwest for at least 245 feet along the contact between syenite and an altered andesite porphyry dike. The width of this poorly exposed vein could not be determined. A sample of the vein contained 4.1 ppm gold, 10 percent arsenic, 0.99 percent antimony, and 0.12 percent tin (Bundtzen and Laird, 1991). The host rocks are part of the Upper Cretaceous intrusive complex of the Russian Mountains.

Comment (Workings): Workings / Exploration = Surface observation and sampling have been completed (Bundtzen and Laird, 1991).

Comment (Reference): Primary Reference = Bundtzen and Laird, 1991

Comment (Geology): Age = Late Cretaceous or Tertiary. Veins crosscut part of the intrusive complex of the Russian Mountains. Quartz monzonite from this complex has yielded a K/Ar age of 70.3 +/- 2.1 Ma (Bundtzen and Laird, 1991).

Comment (Exploration): Status = Probably inactive
