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: Private
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): ORIGINAL CLAIMS STAKED IN 1916 ON W SUMMIT OF HUMBOLDT HILL, ACQUIRED BY FEB 1917 BY NEVADA HUMBOLDT CORP, AND BY -OCT 1918 ORE WAS SHIPPED TO TOULON CUSTOM MILL. A MILL WAS BUI-LT ON THE PROPERTY IN 1918. NEVADA HUMBOLDT CORP CONSOLIDATED -WITH NEVADA MASSACHUSETTS CO IN 1925 AFTER WHICH HUMBOLDT MINE- PRODUCTION WAS NOT REPORTED SEPARATELY FROM DISTRICT TOTAL.

Comment (Deposit): MINERALIZATION WAS CONFINED TO A SECTION FO TACTITE EXTENDING FROM THE OLSEN STOCK CONTACT TO A PREMINERAL FAULT. TACTITE MASSES ARE FOUND IN THREE PARALLEL BEDS.

Comment (Workings): THE HUMBOLDT MINE IS PART OF THE NEVADA-MASSACHUSETTS CO. WORKINGS. THIS MINE IS CONNECTED TO THE SPRINGER AT THE 300-FT LEVEL . 2-COMPARTMENT SHAFT

Comment (Geology): MINERALIZATION WAS CONFINED TO A SECTION OF TACTITE EXTENDING FROM THE OLSEN STOCK CONTACT TO A PRE-MINERAL FAULTY WHICH OFFSET THE BED NORTHWEST, FORMING THE SPRINGER MINE SEGMENT.

Comment (Deposit): THE HUMBOLDT MINE IS PART OF THE NEVADA-MASSACHUSETTS CO. WORKINGS. MINING HAS ADVANCED FROM OUTCROP DOWN TO THE 1800 FT-LEVEL. THREE PARALLEL BEDS ARE WORKED IN THE MINE THE HUMBOLDT, SPRINGER, AND THE GEORGE THE HUMBOLDT AND SPRINGER MINES WERE ORIGINALLY WORKED SEPARATELY THEN BELOW THE 300 LEVEL THE MINES WERE CONNECTED AND THE SPRINGER MINE WAS WORKED FROM THE HUMBOLDT MINE SHAFT. THE HUMBOLDT MINE IS LOCATED ON THE STANK-HUMBOLDT BELT EAST OF THE STANK FAULT. ALONG THIS SAME BELT ARE ALSO THE G/DD, STANK, YELLOW SCHEELITE, KEYES, GEORGE, AND SPRINGER WORKINGS, HUMBOLDT-SPRINGER MINES PRODUCED 60% TOTAL ORE PRODUCED IN DISTRICT, 1917-1943. ; INFO.SRC : 1 PUB LIT

Comment (Location): ON NW SIDE OF HUMBOLDT HILL, ON EAST SIDE OF EUGENE MOUNTAINS BETWEEN SPRINGER AND OLSEN CANYONS

Comment (Reserve-Resource): STAGER, H. K., IN PREP.

Comment (Production): AFTER 1925, PRODUCTION OF HUMBOLDT MINE WAS INCLUDED IN TOTAL DISTRICT PRODUCTION REPORTS
