The Mt. Aspid is a gold, molybdenum, and copper 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 (Workings): Workings / Exploration = Brief reconnaissance mapping and 6 soil or silt samples. Zinc and silver were low, however samples yielded gold to as high as 0.04 ppm (detection limit 0.01 ppm) and copper as high as 330 ppm.
Comment (Reference): Primary Reference = Christie, 1974
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Copper porphyry, epithermal gold vein
Comment (Deposit): Model Number = 17, 25
Comment (Geology): Geologic Description = A 3,000 ft by 3,000 ft (900 m by 900 m) color anomaly is developed in hornfelsed volcanic rocks intruded by a quartz-eye porphyry and hornblende quartz diorite. Mineralization is apparently related to the quartz-eye porphyry (+/- plagioclase phenocrysts) and consists of pyrite and trace amounts of chalcopyrite. Fracture-controlled sulfides are generally weakly developed and related to local silicification and/or fracture-controlled sericite. Minor quartz veining occurs. Christie (1974) reported a covered area about 600 ft by 1,000 ft (180 m by 305 m) exists persumably within the color anomaly area, suggesting a target might lie underneath. However, he also stated that fringing outcrops around this covered area were not well mineralized. Fracturing is generally weak.
Comment (Geology): Age = Miocene or younger
