The mine was previously owned by Rio Tinto Energy America. In 2008 Rio Tinto spun the most significant of its Powder River Basin coal assets — including the Spring Creek Mine — off into Cloud Peak Energy, a company in which Rio Tinto has a 48.3% stake.
In March 2019, a U.S. federal magistrate ruled that Cloud Energy's plans to expand the mine (adding 120 million tons of reserves) were insufficient, because they failed to adequately consider the potential climate change impacts of expanding the mine.
In June, 2011 Cloud Peak Energy signed a 10-year deal to ship basin coal to Asia from a port on Canada’s Pacific Coast. Cloud Peak Energy Inc. signed the deal with Westshore Terminals to ship coal through its Westshore Terminal in Vancouver, British Columbia. The company shipped 3.3 million tons of coal through the terminal to Asian customers in 2010. Cloud Energy operates the Antelope Coal Mine, Cordero Rojo Mine, Spring Creek Mine, Decker Mine, and Jacobs Ranch Mine in the Powder River Basin.
The workforce was furloughed for four months during the Covid 19 pandemic.
In March 2020, the state of Montana approved an expansion of the mine, which may increase capacity to 18 million tons per annum, until 2031. A year later, in February 2021, a U.S. District judge blocked the proposed expansion.
