The Moose Creek is a zinc, copper, silver, and 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.

Comments
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Jurassic or younger; host is a Jurassic age gneissic hornblende quartz diorite.
Comment (Reference): Primary Reference = Berg and Cobb, 1967
Comment (Geology): Geologic Description = Heavily mineralized zone in Jurassic gneissic hornblende quartz diorite. The 25-30 ft thick zone reportedly traced for 7,000 ft along surface. Zone contains irregular masses, veins, and disseminations of pyrite, pyrrhotite, chalcopyrite, magnetite, and sphalerite. The zone trends parallel to gneissic banding; strikes N 60 to 75 W, and dips 65 S to vertical (Capps, 1919). It's bordered by disseminated sulfides and capped by gossan. One massive sulfide body measuring 25 by 80 ft was exposed in an open cut. The sulfides also occur in segregated masses.? Assays show 0.04 to 0.08 oz/ton Au, 0.8 to 1.2 oz/ton Ag, 5.6 percent Cu, and one sample had 0.03 percent Ni (Capps, 1919).
Comment (Production): Production Notes = No record of production (Berg and Cobb, 1967).
Comment (Workings): Workings / Exploration = Explored by open cuts and a short, 32 ft adit. Assays show 0.04-0.08 oz/ton Au, 0.8-1.2 oz/ton Ag, 5.6 percent Cu, and one sample had 0.03 percent Ni (Capps, 1919).
Comment (Geology): Age = Host rock is Jurassic.
