Henrietta Mine

The Henrietta Mine is a silver and gold mine located in Pershing county, Nevada at an elevation of 6,079 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.

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): THE ORE IS IN A QUARTZ-SULFIDE VEIN FROM 4 INCHES TO 4 FEET THICK, WHICH LIES IN A THRUST FAULT IN GREENSTONE AND SCHIST. THE ORE IS OXIDIZED ABOVE THE 400 FOOT LEVEL WITH CARBONATES OF PB & ZN PREDOMINATING. AT DEPTH THE BANDED NATURE OF THE VEIN IS LESS APPARENT WITH THE QUARTZ AND SULFIDES BECOMING AN INTIMATE MIXTURE.

Comment (Deposit): BASE- AND PRECIOUS- METAL-BEARING QUARTZ VEINS CUT METAMORPHIC ROCKS (SCHIST, HORNFELS, QUARTZITE, CHERT AND GREEN-STONE). VEINS CONSIST OF SPHALERITE, PYRITE, GALENA AND ARSENO-PYRITE IN A GANGUE OF QUARTZ AND LESSER CALCITE. THESE MINERAL-S WERE RECOGNIZED IN SULFIDE-BEARING DUMP AND ORE BIN SAMPLES.- FOLIATED META-QUARTZ EYE RHYOLITE PORPHYRY WAS NOTED ON THE D-UMP OF THE UPPER MAIN ADIT. ALTERATION OF WALLROCKS IS NOT ESP-ECIALLY WELL-DEVELOPED.

Comment (Workings): TUNNELS STOPES. TWO ADITS WITH LARGE DUMPS; SEVERAL SMALLER DUMPS. ORE BINS, OLD BUILDINGS AT UPPER WORKINGS.

Comment (Deposit): THE MINE WAS ORIGINALLY WORKED FOR AU/AG VALUES IN THE OXIDIZED ZONE, BUT PB, AG, & ZN INCREASED IN THE SULFIDE ZONE. THE MINE WAS WORKED INTERMITTANTLY UNTIL 1950. THE MINE IS DEVELOPED BY FOUR TUNNELS THAT FOLLOW THE FAULT ZONE FROM WHICH THE ORE WAS STOPED. DISCOVERED IN 1870'S, RELOCATED IN 1912 ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Deposit): Discovery Year: 1870'S

Comment (Location): UTM IS FOR UPPER WORKINGS. SAMPLE 2333 WAS TAKEN AT LOWER ADIT; PREVIOUS QUAD DESIGNATION = KYLE HOT SPRINGS (1961) 1:625000

Comment (Production): PRODUCTION FIGURES INCLUDED IN THE IMPERIAL GROUP REPORT (FOR WHOLE DISTRICT)

Comment (Development): RELOCATED IN 1912, WORKED INTERMITTENTLY UNTIL 1950. NO ACTIVITY AT TIME OF EXAMINATION IN 1984
