Deposit: Deposits are mined from open cuts, and upon sorting. The material yields 1 ton ore per 4-5 tons of material. The sorted ore runs 45% mn, 10.5% s1o2, and a little iron. ; info.src : 1 pub lit; 3 field observ
Deposit type: Replacement Mn
Geology: Lenslike bodies of psilomelane and pyrolusite assoc. With rhodonite and rhodochrosite As large As 25 ft. In diameter and 2 ft. Thick. Many other lenses of oxidized ore occurred which were 10-25 ft. In diameter, and 1-2 ft. Thick. Unoxidized lenses of manganiferous chert in which the manganese occurs As rhodonite form replacement deposits in shale and quartzite. The largest lenses are 50 to 75 ft. In diameter and 6 to 10 ft. Thick
Rock formation(s): Pumpernickel
