The Inmachuk River Area is a gold and tin 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): A PRODUCTIVE PLACER AREA OF APPROXIMATELY 50 SQ MI.; INCLUDES TRIBUTARIES OF LOWER INMACHUK RIVER; AREA OF INTEREST W & SW OF GIVEN LOCATION LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Commodity): AU RECOVERED ROUGH; AUGULAR FLAKES ALSO, SMOOTH, REWORKED
Comment (Production): NO FIGURES AVAILABLE, ALTHOUGH PRODUCTION MUST HAVE BEEN FAIR TO GOOD
Comment (Development): CONTINUOUS MINING FROM 1912 TO 1963 (DREDGES AT INMACHUK & PINNEL RIVERS)
Comment (Deposit): MOST PRODUCTION FROM DREDGES ON INMACHUK & PINNEL RIVERS
Comment (Workings): FAIRHAVEN DITCH, COMPLETED IN 1908, BROUGHT WATER 40 MILES FROM IMURUK LAKE, ENABLED LARGE-SCALE ACTIVITY TO INCREASE IN THIS AREA; SOME DRIFTING TO RECOVER GOLD OVERLAID BY LAVA FLOWS; MUCH OF GRAVEL FROZEN
Comment (Geology): SOME OF GRAVEL MINED MAY BE CORRELATIVE TO TERTIARY KOUGAROK GRAVEL ; MAJOR.UNITS: PREDOMINENTLY SCHIST, LIMESTONE, WITH GRANITIC INTRUSIONS ; REG.COM: LODE DEPOSITS, LOCATED IN SCHIST BEDROCK, WITHIN THE AREA ARE MOST PROBABLE SOURCES OF GOLD AND OTHER MINERALS
