Appears to be the Arizona Magma Mine. If this is so, over the 86-year life of Magma Copper’s Superior project (1911-1996) approximately 27.6 million short tons of ore averaging about 4.9% copper were mined, recovering 1,299,718 short tons of copper, 36,550 short tons of zinc, approximately 686,000 ounces of gold and 34.3 million ounces of silver.This four foot long street sign clearly led the way to the Magma Shaft Number 9 - which seems to be the last shaft driven. Six inches tall. Nice Condition. State:Arizona City:Superior Date: ID#45377
