Woodpecker Mine (Mineral Butte Mill and Consolidated property; Silver Pick group; Hall-Gorham group; 4-M1s), Bell Butte area, Mineral Mountain District, Pinal Co., Arizona, USA
A former underground Ag-Pb-Cu-Zn-Au mine located in sec. 35, T2S, R11E, about 1 mile south of the Reymert Mine, seemingly in a straight line from the southern end of the Reymert vein outcrop and about 2¾ miles NW of Bell Butte (3.9 miles NE of Mineral Mountain), on BLM-administered land. This property is on 1 patented claim, purchased in 1950 by the Mineral Mountain Mining and Milling Co., along with the Gorman-Hall group of claims. The single Woodpecker claim is surrounded by the Gorman-Hall claims. Produced during the period 1937 - 1952. NOTE: The Woodpecker claims overlap the Ajax claims. Claims extend into sec. 34. Operated by the Coronado Mining Co.; Glen Linn; Mineral Mountain Mining and Milling (1948). Owned by the Mineral Mountain Mining and Milling Co. (1948).
Mineralization is a vein deposit in a shear zone with a tabular ore body. Hosted in Pinal Schist. Ore control was a NW-trending fissure zone with crustification textures. Ore concentration was leaching and oxidized mineralization at near surface. The shear zones dip 40°SW. The vein is a silicified mineralized shear zone with one shaft and extensive underground work done on it. It is referred to as the Woodpecker vein and is the only vein which has been worked. The mineralization is associated with a Tertiary intrusive and volcanic period 15.8 to greater than 17.4 M.Y. Quartz latite is exposed 1 mile W of the mine. Mineralization appears to be somewhat similar (personal observation) to that of the Reymert Mine.
Workings include 1 old shaft with fairly extensive underground development.
