The Sullivan Creek Placer is a gold, tin, and silver 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 (Location): USGS MF-371, LOC. 30. PRINCIPAL MINING ACTIVITIES IN DISTRICT ON SULLIVAN CREEK NEAR TOFTY. COORDINATES GIVEN FOR MINE AT TOFTY. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Development): MINING 1907-40'S MAINLY BY OPEN CUT AND HYDRAULIC METHODS. DITCH CONSTRUCTED, 1918. DRAGLINE MINING PLANT OPERATED, 1935.
Comment (Deposit): MOST OF GOLD AND CASSITERITE IN BASAL 1-2 FT. OF GRAVEL AND IN CREVICES IN TOP FOOT OF PHYLLITE BEDROCK. GRAVELS ARE 2-14 FT. THICK AND OVERLAIN BY 40-70 FT. OF MUCK AND SILT. BENCH PLACERS HAVE RICH "SPOTS" WITH ELIPTICAL AREAS WITH RICHEST PAY IN THE MIDDLE. AT ONE MINE $200,000 WAS PRODUCED "ALMOST ENTIRELY FROM A SPACE OF 5,000 SQ. FT." CASSITERITE OCCURS AS CEMENT IN BRECCIA OF VEIN QUARTZ FRAGMENTS.
Comment (Geology): MAJOR.UNITS: BEDROCK IS JURASSIC-CRETACEOUS PYRITIZED PHYLLITE AND SLATE CUT BY QUARTZ VEINS; SURFACE DECOMPOSED.
