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 (Deposit): ORE BODY FAULTED OFF AT ABOUT 300 FT DEPTH. QUARTZITE HIGHLY BRECCIATED AND CEMENTED BY SILICA STAINED WITH MN-FE OXIDES. PHYLLITIC SHALE OBSERVED ON DUMP ALONG WITH ABUNDANT GOSSAN. GALENA OCCURS AS CLOTS AND STRINGERS IN QUARTZ VEIN WHICH CUTS WHITE QUARTZITE ALONG WITH MINOR PYRITE. COPPER OXIDES AND CRYSTALLINE JAROSITE ALONG WITH MUSTARD YELLOW OXIDES (SB OXIDES?) COAT FRACTURES AND BRECCIA FRAGMENTS. YUBA DIKE EXTENDS TO GENERAL VICINITY OF THE MINE, WHERE IT HAS BEEN INTERSECTED AT DEPTH. ON THE EAST, THE VEIN HAS BEEN CUT OFF BY A FAULT THAT STRIKES N55W, DIP 55SW. 3 VEINS PRESENT, REPORTED TO CONTAIN "5-10 OZ AG TO EACH UNIT OF PB". 2 OF THE VEINS COINCIDE WITH THE HANGING WALL AND FOOTWALL OF THE YUBA DIKE, WHILE THE SO-CALLED "MIDDLE VEIN" IS ALONG A SET OF FRACTURES PARALLELLING THE STRIKE OF AND WHOLLY CONTAINED WITHIN THE DIKE.

Comment (Workings): VERTICAL 2-COMPARTMENT SHAFT WITH CROSSCUTS FROM THE 150, 200, AND 300 FT LEVELS. ALL PRODUCTION WAS FROM ABOVE THE 300 FT LEVEL. 3 OTHER SHAFTS, MANY SURFACE CUTS, TRENCHES, SMALL OPEN PIT IN 1983, STOPES. WORKINGS FOLLOW N30W RANGEFRONT FAULT.

Comment (Geology): ORE OCCURS IN FISSURE VEIN AND BRECCIATED ZONES OF PB CARBONATE IN A QUARTZ GANGUE, WHICH IS USUALLY WHITE. THE MAIN VEIN IS 1 TO 4 FEET THICK. AT DEPTH THE VEIN TERMINATES AGAINST SHALE. HOST ROCKS ARE WHITE TO GREY BANDED QUARTZITE DIPPING SW UP TO 40, PHYLLITIC SHALES. GRANITE PORPHYRY DIKE (YUBA DIKE) 40 FT WIDE, DIP 70S.

Comment (Commodity): UNUSUALLY HIGH GOLD CONTENT FOR PIOCHE ORE

Comment (Reserve-Resource): WITH EXPLORATION, THE DOWNWARD EXTENSION OF THE VEIN MAY BE DISCOVERED, WHERE THE VEIN HAS BEEN DISLOCATED BY MOVEMENT ALONG THE CONTACT BETWEEN THE SHALE AND QUARTZITE

Comment (Production): ORE WAS HIGH GRADE, YIELDING $80/TONS IN AG AND AU (1932).

Comment (Development): ALPS SILVER MINING CO OWNED THE OLD FLORAL MILL. NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT TAILINGS HAD BEEN MILLED RECENTLY AND ONE SHAFT WAS BEING USED AS A LANDFILL. ONE OF THE OLDEST MINES IN THE DISTRICT, THE ALPS SHAFT HAD ALREADY BEEN SUNK TO A DEPTH OF 115 FT BY 1871.

Comment (Location): JUST N OF WIDE AWAKE MINE
