Franchise historyEdit

The Butte Copper Kings, named for the once-powerful owners of the copper mines of Butte, Montana, began play in the Pioneer League in 1978 as a co-op team with players from the Philadelphia Phillies, Oakland Athletics, Seattle Mariners and Texas Rangers organizations as well as a few free agents.[1]

Beginning in 1987, the franchise had been operated by Silverbow Baseball. It was sold in 1996 to the Goldklang Group in a move necessary to stem conflict-of-interest issues when Silverbow head Jim McCurdy had taken the position of President of the Pioneer League in 1994.[2] Silverbow had attempted to sell the franchise in 1994 to investors from California, but the deal fell through when it was discovered that the would-be owners had lied about their personal financial backgrounds.[3]

Following the 2000 season, the team relocated to Casper, Wyoming as the Casper Rockies (and was renamed the Ghosts before the 2008 season[4]) and affiliated with Colorado.[5]

On January 13, 2011, Casper Professional Baseball Club, LLC announced the sale of the team to Monfort Investment Group, a group headed by Colorado Rockies General Partners. [6]

October 17, 2011, Grand Junction city officials unanimously approved a lease agreement to the team, making Suplizio Field home to the newly renamed Grand Junction Rockies.[7]
