From South Carolina Sportsman:

According to reports from the National Rifle Association and Charlotte-based Ammoland.com, the primary lead smelter at Herculaneum, Mo., will close its doors at year’s end.

The smelter, owned and operated by the Doe Run Company, has been in existence at the same location since 1892. It is the only smelter in the country that can convert raw lead ore into lead bullion mined from large deposits in Missouri.
