While he declined to detail the identity of the buyer or any financial terms, company spokesperson Brian Aiello said the operation and about 30 million tons of reserves — officially known as the Hidden Valley reserves — are no longer part of the Pennsylvania-based producer’s portfolio.

Emery, located in Price, about 110 miles from Salt Lake City, was part of Consolidation Coal and was owned in its entirety by CONSOL since 1993, when it purchased the operation from its partner in a joint venture.

The company idled the operation in October 2010; at that time, it did not indicate any future reopening plans. It closed its Mine 84 at the same time.
