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 (Commodity): BARIUM PRESENT IN ANALYSED ORE. MINE IN THE REX-SNOWSTORM MINERAL BELT.

Comment (Development): 3 PATENTED CLAIMS IN THE STANDARD-MAMMOTH GROUP; 34 PATENTED CLAIMS IN THE MACE GROUP.

Comment (Deposit): DEPTHS TO TOP, BOTTOM, ARE EXPRESSED IN ELEVATION ON STANDARD-MAMMOTH VEIN

Comment (Workings): DEPTH BELOW SURFACE IS A 1923 FIGURE

Comment (Production): Crosby (1959) combined production of Standard-Mammoth and Greenhill-Cleveland mines.

Comment (Reserve-Resource): Reserves long depleted.

Comment (Orebody): The Standard-Mammoth orebody pitches steeply down to the east coincident with the intersection of the vein with the Standard Fault on the vein's east end. The vein frays out and narrows to the west.

Comment (Deposit): MAMMOTH MINE PORTION HAD OXIDIZED ORE NEAR SURFACE. BURKE FORMATION STRIKES N 39 DEG W, DIPS 45 - 75 DEG SW.

Comment (Commodity): Standard-Mammoth Mill was located down Canyon Creek from the mine at a point just northeast of Wallace in section 26, T48N R4E.

Comment (Production): Asarco data; includes Standard, Mammoth, and Greenhill-Cleveland mines.

Comment (Production): Mitchell and Bennett (1983) using US Bureau of Mines and Asarco data. "Grades" are in terms of metal recovered at smelter per ton of ore, not the amount of metal in the ore. Data for Standard-Mammoth mine only.

Comment (Production): Mitchell and Bennet (1983) from US Bureau of Mines data. "Grades" are reported in terms of reovered metal per ton, not the amount of metal in ore. Production for Greenhill-Cleveland mine only.
