The Sulphide Zinc-Lead-Silver Prospect is a zinc, lead, and silver mine located in Alaska at an elevation of 39 feet.

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.

Comment (Location): USGS B 1525, FIG. 73, TRENCH NO. 1. LOCATION IS AT SITE OF HIGHEST COMBINED VALUES AT TRENCH NO. 1. TRENCH NOS. 2-5 EXTEND 800 FT. SE OF TRENCH NO. 1. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Workings): 5 OPEN CUTS OVER LENGTH OF 830 FT. ALONG NW STRIKE (TRENCHES NOS. 1-5)

Comment (Development): STAKED IN 1928 AS 3 "IDAHO" CLAIMS, RESTAKED IN 1939 AS 40 PERCENT GROUP, TRENCHING DONE THEN, RELOCATED AS MAYBE GROUP IN 1955, SULPHIDE GROUP OF 16 CLAIMS 1969-70, 4 "ICEBERG" CLAIMS ACTIVE AS OF 1975.

Comment (Deposit): POORLY DEFINED BANDS OF DISSEMINATED AND MASSIVE SULFIDES UP TO 0.4 FT. THICK ROUGHLY PARALLEL FOLIATION OF RUSTY FELDSPATHIC GNEISS AND QUARTZITE. SPHALERITE, GALENA, CHALCOPYRITE, PYRRHOTITE, AND MARCASITE FOLLOW SELECTIVE HORIZONS IN MINOR FOLDS, AND ARE CONCENTRATED IN CREST OF SMALL FOLDS AND AS GRAINS AND STRINGERS PARALLEL TO FOLIATION. SULFIDES HAVE BEEN METAMORPHOSED. MINERALIZED ZONE RANGES FROM 5-15 FT. IN WIDTH, AND CRUDELY DEFINES SINGLE ZONE 830 FT. LONG.
