The Archangel 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.
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.

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).

Comments
Comment (Reference): Primary Reference = Capps, 1916
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)
Comment (Geology): Geologic Description = A gold-quartz vein, up to 38 inches thick, cuts Late Cretaceous to Tertiary age tonalite (Capps, 1916). The tonalite ranges in composition from biotite-hornblende tonalite to, 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 (Workings): Workings / Exploration = Capps (1916) reports that Archangel prospect had two 35 ft tunnels. In 1925, Brooks refers to what appears to be the same prospect as the Alaska-Willow Creek claim and reports it to have an adit driven 240 ft.
Comment (Geology): Age = Late Cretaceous or younger; vein cuts Late Cretaceous to Tertiary tonalite.
