Imlay Mine

The Imlay Mine is a gold, silver, and tungsten mine located in Pershing county, Nevada at an elevation of 5,400 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): WORKED BETWEEN 1907 AND 1918, AND IN 1935. IN MARCH 1936 THE MINE WAS IDLE. A SMALL TONNAGE OF ORE ESTIMATED TO CONTAIN ABOUT 0.5 % W03 WAS MINED IN 1956. CURRENTLY BEING PROSPECTED BY OWNE-R, WILLIAM DALE(?)(UNCERTAIN OF LAST NAME) WHO LIVES IN IMLAY -CANYON, BY BULLDOZER TRENCHING. ANACONDA IS SUPPOSED TO EXAMIN-E THE PROPERTY. OWNER STATES THAT ENTIRE VEIN ZONE.WILL PAN FR-EE GOLD. HE STATES THAT HE RAN 10 YDS OF DUMP THROUGH HIS PLAC-ER MILL AND RECOVERED ABOUT $40./YD IN GOLD.

Comment (Location): GOOD ACCESSIBILITY BY MAINTAINED DIRT ROAD IN IMLAY CANYON. UTM LOCATIONS FOR THE 3 NBMG SAMPLES AT THE PROPERTY A-RE AS FOLLOWS: 2526- N4494775, E400200; 2527- N4494975, E40025-0; 2528- N4494975, E400250.

Comment (Geology): QUARTZ FISSURE VEINS IN OR NEAR FAULT ZONES AND SOMETIMES AT CONTACTS OF DIABASE DIKES.

Comment (Deposit): THE IMLAY MINE WAS WORKED BETWEEN 1907 AND 1918 AND IN 1935. MARCH 1936 THE MINE WAS IDLE. THE MINE WAS DEVELOPED BY A VERTICAL SHAFT 250 FT. DEEP AND AN ADIT 1500 FT. LONG DRIVEN FOR DRAINAGE. A MILL WAS OPERATED NEAR THE MINE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Deposit): QUARTZ FISSURE VEINS IN OR NEAR FAULT ZONES AND SOMETIMES AT CONTACTS OF DIABASE DIKES. ZONE OF QUARTZ VEINS AND STOCKWORKS IS ABOUT 10 M WIDE. WALLROCK IS SERICITIZED PHYLLITE. THE QUARTZ VEIN WORKED- IN EARLY 1900'S IS ABOUT 0.33 M WIDE. SB-PB OXIDE STAINS, ABU-NDANT LIMONITE CASTS AFTER PYRITE. AREA IS NEAR CONTACT WITH U-PPER MEMBER PRIDA CARBONATES APPROXIMATELY 30-40 M ABOVE CONTA-CT. DEPOSIT APPEARS TO HAVE SOME POTENTIAL FOR BULK-MINEABLE A-U. GOOD ZONE OF QUARTZ STOCKWORKS AND ABUNDANT FE OXIDE AFTER -PYRITE IN PHYLLITES WITH LOCALLY STRONG SERICITIC ALTERATION.

Comment (Workings): A VERTICAL SHAFT 250 FT DEEP AND AN ADIT 1500 FT LONG DRIVEN FOR DRAINAGE. A MILL WAS OPERATED NEAR THE MINE.CURRENTLY, NUMEROUS BULLDOZER TRENCHES

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.
