Boat Harbor

The Boat Harbor is a zinc, 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 (Workings): Workings / Exploration = Sampling of the vein during brief U.S. Geological Survey field work in 1993 yielded 100 ppb Au, 0.12 ppm Hg, 14 ppm Ag, 4,700 ppm Cu, 3,700 ppm Zn and 110 ppm Pb (sample 93 AWs 16). A mineralized sample of the volcanic breccia yielded 50 ppb Au, 11 ppm Ag, 4,700 ppm Cu, and 4,000 ppm Zn (sample 93 AWs 16b).

Comment (Deposit): Model Name = Polymetallic vein

Comment (Geology): Geologic Description = Volcanic breccias of the Finger Bay Volcanics are cut by a shear or fault zone, exposed in quarry. Zone is filled by quartz vein carrying abundant sulfide minerals, including chalcopyrite. Malachite/azurite staining coasts surrounding rocks. Epidote veins and segregations are common in vicinity of vein -- one float boulder of epidote was 30 cm in diameter.

Comment (Geology): Age = Tertiary
