The company describes itself as "a coal marketing, mining and infrastructure company that aspires to become the largest supplier of United States thermal coal to the Asia-Pacific market."
The lawsuit over the Decker mine claimed Ambre knew about plans to end production when it bought its 50 percent stake and took over management of Decker Coal Co. last year. The suit said the company and its subsidiaries have been acting outside of its joint-venture agreement to position itself for an expansion of Decker coal production.
Ambre is seeking to dismiss the case, which is before U.S. District Judge Richard Cebull.
They company's attorneys stated in court filings that it is not the direct owner of the Decker mine, and has reached no agreements with prospective customers to ship the coal overseas. As a result, the company said the court lacks jurisdiction.
Western Minerals filed motions this week urging the court to not dismiss the case.
