Mogul

The Mogul 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.

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.

Alterations

Alteration Type: L
Alteration Text: Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954). Oxidation of sulfide minerals.

Comments

Comment (Reference): Primary Reference = Capps, 1915

Comment (Workings): Workings / Exploration = Development consists of three open cuts made across vein which reportedly had high assays in gold (Capps, 1915).

Comment (Commodity): Ore Material = sulfides

Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)

Comment (Commodity): Ore Material = sulfides

Comment (Geology): Geologic Description = Gouge zone containing quartz veins in early Paleocene and Late Cretaceous quartz diorite. The vein quartz is drusy and contains scattered unspecified sulfides and much iron oxide. The quartz vein is 1 is 4 inches thick in all three open cuts. In one cut the vein is separated from another 12 inch quartz vein by 18 inches of altered quartz diorite. The vein was reported to have given high assays in gold (Capps, 1915).? the early Paleocene and Late Cretaceous quartz diorite is part of a pluton which is mostly biotite-hornblende tonalite with lesser biotite-hornblende quartz diorite. Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Late Cretaceous or younger; veins cut early Paleocene and Late Cretaceous quartz diorite.
