The Good Hope 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 vein 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 (Exploration): Status = Inactive
Comment (Workings): Workings / Exploration = First staked in 1916. Vein exposed by two large open cuts (Capps, 1919).
Comment (Reference): Primary Reference = Capps, 1919
Comment (Geology): Geologic Description = A quartz vein several feet wide in Tertiary to Late Cretaceous biotite-hornblende tonalite and lesser biotite-hornblende quartz diorite is reported to contain gold (Capps, 1919). Wall-rock alteration within a few inches of the vein 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). Free gold can be panned from the vein.
Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)
Comment (Geology): Age = Late Cretaceous or younger; quartz vein cuts Tertiary to Late Cretaceous tonalites and quartz diorites.
