Lemon claims

The Lemon claims is a iron, 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 (Workings): Workings / Exploration = Explored by short adits and diamond drilling. 188-foot core sample (Lemon Extension #2, Pilgrim, E.R., 1931) contained 0.3 TO 3.8 % Cu, average 0.95% Cu. Weighted averages from channel samples, Lemon Claim #2 (USGS OFR 76, p. 16) contained 0.71% Cu, 0.024 oz./t Au, 0.66 oz./t Ag. 8-foot channel sample from massive sulfide body 30 ft. long and 3 to 8 ft. thick (USGS OFR 76, p. 10, 11, table 2 no. 27) contained 0.32% Cu, 0.08 oz./t Au, 6.12% Zn, 38.84% Fe. Surface and underground workings.

Comment (Geology): Age = Early Cretaceous

Comment (Deposit): Other Comments = Considered as part of Orange Hill porphyry copper deposit. This listing contains data specific to contact metasomatic deposits associated with the quartz diorite at Orange Hill. See Orange Hill deposits (NB043).

Comment (Geology): Geologic Description = Disseminated pyrrhotite, pyrite, and chalcopyrite in magnetite-rich skarn and veins of pyrite, chalcopyrite, and sphalerite in magnetite bodies and cutting skarn; some stringers of bornite and magnetite. Skarn developed in Permian limestone adjacent to Cretaceous quartz diorite intrusive and to porphyry Cu-Mo deposit at Orange Hill. Skarn grades outward into hornfels.

Comment (Exploration): Status = Inactive

Comment (Deposit): Model Name = Contact metasomatic, skarn
