The Financial Post reports in its Saturday, July 19, edition that an idle Cape Breton underground coal mine that has been plagued by rockfalls is reportedly up for sale. A Canadian Press dispatch to the Post reports that Nova Scotia-based Morien Resources receives a royalty from the Donkin mine, and says the mine's owner has announced it intends to explore a sale of its 100-per-cent ownership in the operation. Attempts to reach mine owner Kameron Colliers ULC were unsuccessful. Morien owns a production royalty on coal sales from the mine that is binding and will continue if there is a change in ownership. The Nova Scotia company says it is unclear whether a sale will result in the mine restarting operations. Nova Scotia's government suspended operations at the mine in 2023 after two roof rockfalls and allowed them to resume in March, 2024. The mine, which remains idle, first opened in 2017, and was described by the province as the world's only operating subsea coal mine. It resumed operations in September, 2022, after it was shuttered in March, 2020, amid slumping coal prices and roof collapses that led to repeated stop-work orders.
