Peak 2710

The Peak 2710 is a copper and zinc 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 (Commodity): Gangue = manganese oxides

Comment (Deposit): Model Name = Lode; hornfels and sulfide mineralization related to emplacement of rhyolite porphyry.

Comment (Deposit): Other Comments = See MAS/MILS Sequence # 0020330006 (USBM, 1995)

Comment (Geology): Geologic Description = Locally high-grade lenses of Cu sulfides, sphalerite, galena and magnetite in thermally altered calcareous argillite intruded by rhyolite porphyry dikes and sills. Fe and Ma staining are abundant in contact zone. Mineralization can be traced 75 ft (23 m) in rubble. Nearby rocks include Paleozoic? black phyllite, maroon and green argillite, calc argillite, quartzite and limestone (Neruokpuk Fm.?), and are locally malachite or manganiferous stained (Barker, 1981, p. 64-68, 75-9).

Comment (Workings): Workings / Exploration = 'Manganiferous' granite contains <300 ppm Cu, 2.0% Zn, 1500 ppm Pb and 6 ppm Ag (Brosge and Reiser, 1968). Skarn with quartz, magnetite and sulfides contains 8.6% Cu, 8700 ppm Pb, 3800 ppm Zn, 43 ppm Ag. Gossan with malachite contains 8 ppm Mo, 767 ppm Sn, 102 ppm Be, 5500 ppm Cu, 1.1% Pb, 1.2% Zn, 84 ppm Ag and 160 ppm U. Hornfelsed argillite contains 55.6 ppm Th, 14.4 ppm U. Soils contain up to 290 ppm Cu, 4100 ppm Pb, 6400 ppm Zn, 0.9 ppm Ag (Barker, 1981, p. 78).

Comment (Reference): Primary Reference = Barker (1981)

Comment (Exploration): Status = Inactive
