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 (Deposit): EPITHERMAL FISSURE VEINS, CLAIMS COVER AN AREA OF 330.5 ACRES.. HAULAGE IS BEING DONE FROM AN INCLINE THAT CROSSCUTS TWO PARALLEL NE-TRENDING VEINS THAT ARE BEING EXPLORED AND DEVELOPED SIMULTANEOUSLY IN 2 DIFFERENT DIRECTIONS. THE FOOTWALL VEIN IS NARROWER AND OF SLIGHTLY HIGHER GRADE THAN THE SANGER VEIN, WHICH IS WIDER, LONGER, AND OF SOMEWHAT LOWER GRADE. A HAND-HELD SILVER PROBE (GAMMA DEVICE) IS BEING UTILIZED TO ESTIMATE SILVER VALUES AT THE MINE FACES. THIS TECHNIQUE ALLOWS THE MINERS TO SELECT THE AREA OF HIGHEST SILVER VALUES ACROSS THE MINE FACE BEFORE SETTING EACH ROUND AND FOR STORING ON THE SURFACE ORES OF DIFFERENT GRADE

Comment (Workings): SEVERAL SHALLOW CUTS AND 60 FT OF SHAFT WORK, 42 FT OF TUNNEL WORK BY 1920'S. SHAFT, INCLINE AND 1500 FT OF UNDERGROUND WORKINGS

Comment (Geology): LOW GRADE ORE HAS QUARTZ GANGUE; HIGH-GRADE ORE HAS CALCITE GANGUE; BEST GRADE ORE HAS BARITE GANGUE

Comment (Location): 0.7 MILES N 15 W FROM MOHAWK MINE.. UTM IS TO MAIN SHAFT ON THE PROPERTY ; INFO FROM LAND.ST :(1972)

Comment (Development): WAS STILL PRODUCING IN 1977, A SMALL PRODUCTION OF SILVER WAS REPORTED FROM THE FRANCIS MINE IN 1922. IN 1984, THERE WAS A SIX-MAN CREW MINING AND DEVELOPING ALONG BOTH ENDS OF 2 PARALLEL VEINS, WITH A WORK SHOP, ORE PADS AND LIVING QUARTERS ON THE PROPERTY.
