As a result, the coke producer estimates full-year adjusted earnings of $205-$230 million, down roughly $40-$50 million from 2012.

The company said it would mitigate the impact of the lower coal sale prices through a plan intended to improve efficiencies and lower costs at its Jewell and Revelation mining operations.

Total coal sales for 2013 are projected to be 1.7 million tons, up slightly from 2012’s 1.5Mt sold.

On the coke side, the company expects production to exceed 4.3Mt, thanks largely to the startup of its Middletown plant in Ohio.
