CASPER, Wyo. (AP) — One of Wyoming's largest coal producers has cut 15 salaried jobs, including most of its lobbying team.

Gillette-based Cloud Peak Energy confirmed the moves Monday but didn't provide details about the layoffs.

Cloud Peak owns the Antelope and Cordero Rojo mines in Wyoming and the Spring Creek mine in Montana.

In a note to employees last week, the company said the cuts were made in response to the current challenges in the coal market. It said the cuts and its recent decision to hire outside advisers to consider options for its future, including selling the company, are necessary to help position it for the future.

In December, the New York Stock Exchange warned the company it could be delisted if its weak stock performance continued.
