Mining Ruins, South Mountain Park, Arizona
Max Delta Mine
We explored these mining ruins and found one cave that was still open. The entrance was approximately 2.5-3 feet high and opened up to maybe 4 feet high about 20 yards inside. The cave traveled as far as the light could penetrate the darkness. There were 2 old cement structures left with at least 7 imploded caves around the property.
A former surface and underground Au-Ag-Cu mine located about 9 miles South of the railroad at Phoenix in the northern portion of South Mountain on state park land. Discovered 1895 and produced 1913-1942. Owned by T.C. McReynolds, Jr.; and, the Ace Mining & Development Co. Workings include a 500 foot deep shaft & extensive drifts (about 2,500 feet of tunnels & some stopes). Produced 1,600 tons of ore from 1933-1934.
