Warrior is a large-scale, low-cost producer and exporter of premium quality met coal, also known as hard coking coal (“HCC”), operating highly efficient longwall operations in its underground mines based in Alabama. The HCC that Warrior produces from the Blue Creek coal seam contains very low sulfur and has strong coking properties. The premium nature of Warrior’s HCC makes it ideally suited as a base feed coal for steelmakers. For more information, please visit www.warriormetcoal.com.
