Lietzke

The Lietzke 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 (Deposit): Other Comments = Grant and Higgins (1909) did not visit this occurrence and their description is based on hand samples. Subsequent authors have reprinted their description.

Comment (Reference): Primary Reference = Grant and Higgins, 1909

Comment (Reserve-Resource): Reserves = None reported.

Comment (Deposit): Model Name = Massive sulfide?

Comment (Geology): Geologic Description = Martin and others, (1915) examined hand samples from this occurrence and described them as quartz containing fragments of diabase, pyrite, and a little chalcopyrite. They then went on to speculate that this occurrence is similar to the Fairview and Iron Mask prospects (Martin and others, 1915). Tysdal and Case (1979) described the bedrock geology in this area as Cretaceous, pale to dark green aphyric to porphyritic pillow basalts with subordinate pillow breccia, tuff, and siltstones. Along the west shore of Resurrection Bay the pillows are right side up, dip 30 to 50W, and the long axes of the pillows and pillow bifurcation plung westward down dip.

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Cretaceous.
