Kennecott Utah Copper discovers molybdenum deposit

Kennecott Utah Copper says it has discovered a huge deposit of molybdenum (ma-LIB-DE’-nem) beneath its Bingham Canyon Mine.

The company says it’s unclear whether it will be feasible to develop a mine to extract the deposit, which is estimated at 500 million tons.

Molybdenum is a byproduct of copper production and is used in high-strength steel alloys. The silvery white metal is also a key ingredient in oil refining.

The company’s open-pit mining operation is scratching the surface of the deposit, but the highest value ore lies about 1,500 feet below the pit bottom.

Kennecott parent company Rio Tinto announced a year ago plans to invest $270 million to build a facility to deeply process and refine molybdenum ore recovered at the Utah mine.
