Snettisham Iron-Titanium-Vanadium Prospect

The Snettisham Iron-Titanium-Vanadium Prospect is a iron, titanium, metal, and vanadium mine located in Alaska at an elevation of 98 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.

Land Status

Land ownership: National Forest
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Development): DISCOVERED BEFORE 1900. 4-5 TONS OF TITANIFEROUS MAGNETITE SHIPPEP TO DOUGLAS FOR ANALYSIS IN 1918. CLAIMS STAKED IN 1950 BY ROBERT COUGHLIN AND W. PEKOVICH. EXTENSIVE DIAMOND DRILLING BY USBM IN 1953.

Comment (Deposit): PYROXENITE PLUTON CONTAINS DISSEMINATED MAGNETITE, ALSO IN CONCENTRATIONS. SMALL AMOUNTS OF PYRRHOTITE, CHALCOPYRITE, ILMENITE FOUND WITH MAGNETITE.

Comment (Workings): 6,543 FT. OF DIAMOND DRILL HOLES DRILLED IN 1953 BY USBM.

Comment (Geology): PYROXENITE PLUTON THAT HAS INTRUDED PHYLLITE, HAS GRADATIONAL CONTACTS WITH DIORITE.

Comment (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.
