The Copper Queen Mine in Bisbee, Arizona is located in one of the most productive mining areas of the world. Before the mines closed in 1975 the mines had produced metals of the value of over $24 billion dollars in 2010 prices. This staggering amount of money came from the production of 8,032,352,000 lbs of copper, 2,871,786 ounces of gold, 77,162,986 ounces of silver, 304,627,600 lbs of lead and 371,945,900 lbs of zinc. Over 50,000 people visit the mine operated by the City of Bisbee to help the unemployed miners. Visitors can ride one of the original mine trains and wear yellow slickers with miner’s hats and a light source. The original mining claim was staked in 1877 and found ore containing 23% copper with gold and silver. Normal mining operations are conducted in mines with only 3% or 4% copper. This extraordinarily profitable mine is still an Arizona attraction.
