The gaping mouth of Resolution Copper Mining’s No. 10 shaft is 28 feet across and opens into a sheer drop of nearly 7,000 feet, making it the deepest continuous mine shaft in the United States. It’s also probably the deepest location where Arizona news reporters have roamed.
In recent months, Resolution Copper Mining — a subsidiary of mining giants London-based Rio Tinto Group and Australia-based BHP Billiton Ltd. — has brought journalists, decked out in helmets, boots and safety harnesses, on tours down the dark shaft. Bloomberg News took a tour last December. Reporters from Arizona Public Media and Phoenix’s Fox 10 ventured down earlier this year. The Star took a turn in April.
“We’ve got a great story,” Resolution project director Andrew Taplin said. “We’re going to generate a lot of economic benefits and we want to tell our story.”
