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Comment (Reserve-Resource): ACCORDING TO UNPUBLISHED (1971) INFORMATION BY R. G. WORL, THE SPOR MTN. DISTRICT RESERVES ARE 328,000 MET. TONS OF 40% CAF2 ORE AND LARGE, LOW GRADE BE AND U DEPOSITS

Comment (Location): SECTION SUBDIVISIONS NW 1/4 NE 1/4 NE 1/4

Comment (Production): THE EAST PIT PIPE WAS THE 2ND LARGEST PRODUCER IN THE DISTRICT

Comment (Development): RECENT URANIUM EXPLOR. INDICATES A FAIR U3O8 CONTENT BUT IT OCCURRS IN COMPLEX STRUCTURE WITH F IONS WHICH MAKES IT ECONOMICALLY MARGINAL FOR EXTRACTION

Comment (Deposit): MOST PROD. HAS COME FROM AN ELIPITICAL SHAPED OPEN PIT 190 FT LONG & 110 FT WIDE. THE MAIN PIT EXTENDED TO A DEPTH OF 80 FT. ORE WAS PRODUCED FROM 4 PIPES (155X105), (30X65 FT), (50X55 FT), (19X40 FT) & 1 VEIN 40X7 FT

Comment (Workings): WORKINGS CONSIST OF OPEN PITS, ADITS, WINZES, & RAISES. ADIT #1 MEASURES 95 FT, ADIT #2 IS 205 FT LONG WITH AT LEAST 280 FT. OF CROSSCUTS. A 3RD ADIT 500 FT. LONG PRODUCED NO ORE

Comment (Geology): ORE VARIES FROM SOFT FRIABLE TO HARD BOX WORKS, AND FROM WHITE-DARK PURPLE

Comment (Reserve-Resource): SULFIDE TAILINGS ARE FROM 3 PRINCIPAL MINES - SANTA BARBARA, SAN FRANCISCO DEL ORO AND LA PRIETA ZINC - LEAD - SILVER MINES.

Comment (Reserve-Resource): TAILINGS ARE FROM 3 PRINCIPAL MINES - SANTA BARBARA, SAN FRANCISCO DEL ORO AND LA PRIETA.

Comment (Workings): 40 MILLION METRIC TONS OF SULFIDE ORE MILL TAILINGS CONTAIN 15 - 20% CAF2. FLUORSPAR IS PRESENT IN THE MINES THROUGH A VERTICAL RANGE OF OVER 700 M.

Comment (Production): ASARCO MEXICANA'S PLANT PRODUCES 50,000 MET. TONS/YR ACID-GRADE AND WAS SCHEDULED TO EXPAND 50% IN 1974. COMPANIA MINERA FRISCO PRODUCED 111,396 MET. TONS IN 1972. AN ADDITIONAL 75,000 M.T./YR PLANT IS SLATED FOR COMPLETION IN 1974.

Comment (Development): MILL TAILINGS FROM ZINC - LEAD - SILVER SULFIDE ORE IS ECONOMICALLY PROCESSED FOR ACID GRADE FLUORSPAR EVEN THOUGH CONCENTRATION IS ONLY 15 - 20% CAF2

Comment (Location): LAT. AND LONG. ARE APPROXIMATE. DEPOSITS CONSIST OF MILL TAILINGS FROM THE SANTA BARBARA, SAN FRANCISCO DEL ORO AND LA PRIETA LEAD - ZINC MINES.

Comment (Commodity): CHIEF IMPURITIES ARE MONTMORILLONITE, CREAM COLORED DOLOMITE & QUARTZ
