The largest industry in the town is American Gypsum's (formerly [[Centex]] and before that, Eagle Gypsum Limited) [[drywall]] plant. The facility produces a variety of wallboard products, which is shipped by both rail and truck. The company also operates an open pit gypsum mine in the hills north of town. The mine currently in operation is the second to have been located in the area. Its grade is quickly dropping, and the company intends to close and reclaim it soon. A new mine, roughly a mile away, has been permitted, and is currently in the development stage. Unlike most surface mines, which utilize drill and blast methods to recover material, the Eagle mine uses machines similar to pavement mills (Wirtgen 2200 SM Surface Miners) to cut {{convert|6|in|mm|adj=mid|-deep}} swaths through the relatively soft rock. Front-end loaders then sort the material by color (white is gypsum, brown is waste) and load it into trucks to be hauled either to the plant or to waste piles.
