With over 2 billion tons of coal reserves, we are among the largest holders of coal reserves in the United States and our reserves can support over 75 years of production at our current production level. We operate three mining complexes in the Illinois Basin.Our mining complexes use highly efficient longwall mining systems. This highly productive mining method coupled with the favorable geology of our coal has resulted in our mines being among the safest, most productive and lowest cost underground coal mines in the United States.
