The Lake Elfendahl Copper-Zinc-Lead Occurrence is a lead, zinc, 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.
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 (Deposit): FISSURE-TYPE QUARTZ VEIN ALONG PERSISTENT FAULT CONTAINS PYRITE, CHALCOPYRITE, SPHALERITE, AND GALENA. PROBABLY CONTAINS GOLD BECAUSE OF PRESENCE OF SPHALERITE AND GALENA, WHICH ARE EXCELLENT INDICATORS IN THIS AREA.
Comment (Workings): OCCURRENCE ONLY
