The Rae 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.

Comments
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Late Cretaceous or younger; shear zone cuts the Late Cretaceous Willow Creek Pluton.
Comment (Commodity): Ore Material = copper carbonates
Comment (Deposit): Other Comments = Capps (1915) reports the San Juan and Rae prospects separately, however because these prospects are very near one another, they are are often reported together as one. The San Juan prospect, contains the pegmatitic material with reported good assays, while the Rae prospect (part of the Jennings Group) has insufficient data about the vein.
Comment (Commodity): Ore Material = copper carbonates
Comment (Workings): Workings / Exploration = Explored primarily by open cuts. There is not enough data to prove or disprove the presence of valuable ore bodies in the vein cutting the gneissic quartz diorite, but pegmatitic rocks show encouraging assays indicating gold to be present (Capps, 1915).
Comment (Geology): Geologic Description = Fault or shear zone in gneissic quartz diorite contains clay or gouge with some quartz carrying free gold, chalcopyrite, pyrite, galena, and copper carbonates. Shear zone or fault is oxidized and is 8 to 18 inches thick. The zone strikes generally northeast and dips 43 N. Pegmatitic rocks with large crystals of quartz and feldspars containing gold reported nearby. Ore not similar to ore in the rest of the district (Capps, 1915).? the gneissic quartz diorite is part of the Willow Creek Pluton, a Late Cretaceous zoned pluton: the outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite.
Comment (Reference): Primary Reference = Capps, 1915
Comment (Deposit): Model Name = Low-sulfide Au-quartz veins ? (Cox and Singer, 1986; model 36a ?)
