Iron King Mine

The Iron King Mine is a iron mine located in Humboldt county, Nevada at an elevation of 7,402 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: BLM Administrative Area
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 (Geology): ORE BODIES ARE REPLACEMENT DEPOSITS IN METAVOLCANIC ROCKS IN N-TRENDING FAULTS NEAR A DIORITE CONTACT ZONE. MAGNETIC STUDIES INDICATE THAT THE MAIN MINERALIZED ZONE IS DIVIDED INTO 3 BLOCKS OFFSET PROGRESSIVELY ON THE NORTH

Comment (Deposit): MINE "HAS BEEN A CONSISTENT PRODUCER OF HIGH-GRADE, HARD-LUMP ORE" SINCE PRODUCTION BEGAN IN THE EARLY 1950'S. AVERAGE ORE GRADE WAS 63% IRON FROM 1952-1954. MINING HAS BEEN BY OPEN PIT METHODS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Location): NEAR HEADWATERS OF SOUTH FORK OF JACKSON CREEK

Comment (Development): OPEN PIT MINE. NO ACTIVITY IN 1984, BUT ROAD UP TO MINE APPEARS TO HAVE BEEN GRADED NOT LONG AGO.

Comment (Deposit): REPLACEMENT ALONG REVERSE FAULTS NEAR IGNEOUS CONTACT.ALSO SOME HORNFELS IN IMMEDIATE AREA, AND WHAT APPEARS TO BE A WHITE ALTERED POROUS RHYOLITE DIKE? WHICH CUTS MET-AVOLCANIC/HORNFELS SEQUENCE IN PIT AREA.

Comment (Workings): OPEN PIT; SEVERAL LARGE OPEN CUTS NEAR RIDGE TOP. ONE ADIT LOCKED WITH IRON DOOR. ADIT TRENDS N60E. SEVERAL OLD BUILDINGS -IN VARIOUS STATES OF DISREPAIR. SEVERAL CUTS FOR MAINTENANCE B-UILDINGS, OFFICE, ETC.
