Arch has one actively producing Illinois Basin mine outside of its 49% ownership in Night Hawk mining. However, the company also controls the Denmark Deep/Pinckneyville reserve, where the future Lost Prairie mine will operate. This reserve is large enough to support a 3.5 Mstpa mine for more than 45 years.
