The Klukwan Fan Iron-Copper-Platinum Placer is a iron, titanium, metal, gold, and copper mine located in Alaska at an elevation of 499 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.

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): ALLUVIAL FAN CONSISTING OF PYROXENITE, GABBRO, AND DIORITE DETRITUS FROM CANYONS 1 AND 2 OF KLUKWAN ULTRAMAFIC PYROXENITE COMPLEX (DEPOSIT NO. SK-16). FAN IS SEMICIRCULAR, WITH BASAL RADIUS OF 6000 FT AND 700 FT THICK, GIVING 500 MILLION TONS OF MATERIAL WITH AN AVERAGE OF 10% MAGNETIC FE (USGS OF 132, P. 35, 36). USBM OF 84-21, P. 5 ESTIMATES 989,761,000 TONS OF MATERIAL AT 10.8% SOLUBLE FE.
Comment (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.
Comment (Deposit): GRADIENT OF FAN 6 DEGREES-10 DEGREES, FLOW RANGES FROM 10-1,000 CFT/SEC. HAYNES HIGHWAY CROSSES ALLUVIAL FAN, PROVIDING GOOD TRANSPORTATION. WORLD CLASS-SIZE DEPOSIT. ; INFO.SRC : 1 PUB LIT
Comment (Workings): CHURN DRILLING, PIT SAMPLING, PILOT MILL CONSTRUCTED FOR TESTING.
Comment (Geology): POORLY SORTED ALLUVIUM, RANGING FROM SILT TO LARGE BOULDERS OF 40 IN DIAMETER ; MAJOR.UNITS: BEDROCK IS CRET META-BASALT UNDER AREA OF FAN ; REG.COM: SOURCE OF PLACER IS KLUKWAN ULTRAMAFIC TITANIFEROUS MAGNETITE-BEARING PYROXENITE UPHILL TO THE NE, IN THE AREA OF DEPOSIT NO. SK-16.
Comment (Commodity): SINCE SOURCE OF PLACER IS KLUKWAN LODE (SK-16), COMMODITIES SHOULD BE SIMILAR
Comment (Location): USGS MF-424, LOC. 15. LOCATION IS IN CENTER OF ALLUVIAL FAN EXTENDING FOR 1 MI. RADIUS. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Development): EXTENSIVE PROSPECTING WITH PIT SAMPLING AND CHURN DRILLING OF PLACER. PILOT MILL CONSTRUCTED, COBBER CONCENTRATES PRODUCED FOR TESTING. 49 PATENTED PLACER CLAIMS, BUT NO PRODUCTION.
