The Mccoy Iron Mine is a iron mine located in Lander county, Nevada.

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): UTM IS FROM NBMG SAMPLE SITE 670

Comment (Workings): OPEN PIT, EXTENSIVE TRENCHING, DREDGING, AND OPEN PITS

Comment (Deposit): A TOTAL OF ABOUT 40,000 LONGS TONS OF ORE AVERAGING 60% FE HAS BEEN OPEN PIT MINED FROM THREE OREBODIES WHICH STRIKE E-W AND DIP. 10-20 SOUTH. FOLLOWING A MAGNETOMETER SURVEY ON THE MCCOY DEPOSIT THE USBM CARRIED OUT A TRENCHING AND DRILLING PROGRAM IN 1944. THEY DRILLED TWO HOLES TO A TOTAL DEPTH OF 92 FEET. NBMG VISITED THE SITE IN 1981, TOOK SAMPLE #670, RESULTS UNKNOWN. ; INFO.SRC : 1 PUB LIT

Comment (Development): OPEN PIT MINE. USBM DID DRILLING AND TRENCHING PROGRAM IN 1944. SITE BEING STAKED FOR GOLFIELDS IN 1981, WITH BLASTING TO SOUTH.

Comment (Deposit): ORE OCCURS AS IRREGULAR MASSES AND BANDS REPLACING DOLOMITE BEDS. OREBODIES LOCALIZED ALONG MINERALIZED FAULTS AND SHEAR ZONES

Comment (Geology): THE IRON ORE OCCURS AS IRREGULAR MASSES AND BANDS REPLACING DOLOMITE BEDS IN THE OSOBB FORMATION. THE OREBODIES APPEAR TO BE LOCALIZED ALONG MINERALIZED FAULTS AND SHEAR ZONES THAT INTERSECT NEARBY INTRUSIVE BODIES OF DIORITE. MAGNETITE OUTCROPS CAN BE TRACED FOR 5,000, HOWEVER TRENCHING PROVED THE ORE BODIES TO BE DISCONTINOUS. THE DRILLING OUTLINED A SMALL TABULAR OREBODY WHICH FEATHERS OUT IN BOTH GRADE AND THICKNESS AT THE EDGES (KRAL, 1947).

Nevada Gold

Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more: Gold Districts of Nevada.
