Willcox Tungsten Prospect

The Willcox Tungsten Prospect is a molybdenum and tungsten mine located in Humboldt county, Nevada at an elevation of 5,440 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 (Development): CLAIM OWNER HAS DRILLED SEVERAL SHALLOW DIAMONG DRILL HOLES ALONG E-W-TRENDING CONTACT ZONE

Comment (Deposit): CONTACT ZONE WITH DISSEMINATED SCHEELITE IN MODERATELY SILICATED LIMESTONE. PYRITE, CHALCOPYRITE, MAGNETITE AND REPORTEDLY SCHEELITE OCCUR IN THE SKARN ZONE. SULFIDES AND SCHEELITE APPEAR -TO BE CONCENTRATED IN A 1M ZONE ABOUT 25 M FROM THE GRANODIORI-TE CONTACT. LIMESTONE HAS BEEN CONVERTED TO MARBLE WITH LOCAL -TREMOLITE. THE INTRUSIVE IS EXPOSED TO THE NORTH OF THE PROSPE-CTS.

Comment (Workings): SEVERAL OPEN CUTS, PROSPECT PITS FOR 1 KM ALONG AN E-W ZONE.

Comment (Geology): LIMESTONE ONLY MODERATELY SILICATED

Comment (Deposit): SCHEELITE DISSEMINATED IN MODERATELY SILICATED LIMESTONE AT AN INTRUSIVE CONTACT. SILICATED LIMESTONE FORMS THE RIDGE SOUTH OF THE PROSPECT, THE INTRUSIVE OCCUPIES THE BASIN TO THE NORTH. CLAIM OWNER HAS DRILLED SEVERAL SHALLOW DIAMOND DRILL HOLES ALONG EAST-WEST TRENDING CONTACT CONE. THIS DEPOSIT COULD BE THE SAME AS THE MOLLY CLAIMS AND THE FORGOTTEN CLAIM (WILLDEN, 1964, TABLE 25) ; INFO.SRC : 1 PUB LIT; 3 FIELD OBSERV
