Arch Resources Powder River Basin coal mines

Arch Resources (Arch) owns two operating mines in the PRB: Black Thunder and Coal Creek. They produce thermal coal for the domestic power sector. Arch is the second largest coal producer in the PRB, accounting for over 20% of the basin's total output in 2024. However, demand for PRB coal is waning, and Arch's production will tumble by 16 Mst Y-O-Y and margins shrink. Wood Mackenzie’s asset reports are built from the bottom up, incorporating a number of granular data metrics to ultimately produce our industry standard cash operating costs. This qualitative analysis is supplemented by the associated Excel download which enables interrogation of a whole series of cost and production metrics over the life of the assets.
