A former small surface Mn-Cu-Baryte mine located in East-central (SE¼NE¼) sec. 16, T.23S., R.24E., on a low spur that extends Eastward from the Gardner shaft, just South of Sacramento Hill, on private land. Owned by the Phelps Dodge Corp. IN 1961, The Mammoth was located along the S side of the Lavendar pit, a short distance E of the Gardner shaft. Assumed to have been subhumed by the growth of the Lavendar pit. Location of the claim is estimated from a mine map in U.S. Bureau of Mines Information Circular 7990, P. 11.
Mineralization is irregular replacement bodies of psilomelane with 'nests' of barite and some copper staining along fractures in Pennsylvanian-Permian Naco Group Limestone, close to the contact with the altered porphyry of Sacramento Hill. In the porphyry are perhaps some included masses of altered Pinal Schist. The ore shows no definite walls and does not follow any persistent zone of fissuring. The ore is psilomelane with nests of barite and a green copper arsenate (NFI). Occasionally a little chalcocite is found. Ore control was the nearby dikes and sills, and faulting with its associated brecciation. Ore concentration included bornite replacing pyrite. Alteration was gossan with Mn and Fe oxides induced by hydrothermal metamorphism. An associated rock unit is the Sacramento Hill Stock. Two manganese deposits on the claim were removed during stripping operations for the Lavendar pit in the early 1950's.
Local structures include common pre-mineralization faulting and tilting. Main fault directions are N10W to N40E and S30W to N50W.
Workings include 2 open pits (Northwesterly & Southeasterly). Up to about 2,000 tons of sorted manganese oxide was produced in 1917-1918. Production included under the Copper Queen Branch of Phelps Dodge Corp. in USBM-ABGMT files.
