The Lucky Jack mine (formerly known as the Mount Emmons molybdenum property[1]) is one of the largest molybdenum deposits in the United States.[2] The mine is located West of Crested Butte, Colorado in Gunnison County, Colorado.[1] The Molybrook mine has reserves amounting to 220 million tonnes of molybdenum ore grading 0.37% molybdenum thus resulting 814,000 tonnes of molybdenum.[2]

History

The unmined deposit was reported to be in the planning stage in 2007 with interests in the project from both U.S. Energy Corporation and Kobex Minerals Inc.[1][3] The deposit was originally discovered in 1970s.[3]

The Denver Post reported grassroots environmental groups, like the High County Citizens' Alliance and the Red Lady Coalition, actively opposing the planned work as of 2007.[4] The groups pointed at expensive and poor cleanup attempts for similar mines in the area, one of which was listed as a Superfund site: Standard Mine.[4]

In February 2016, a subsidiary of Freeport-McMoRan, the operators of the Freeport Mine in Arizona, purchased the claim from U.S. Energy.[5] This news was well received by the town and activist groups, because the new owners were willing to enter a cooperative MOU with both the local town and state and federal environmental regulators on care of the mine.[5]
