There are several other lithium projects under development in the United States today, but ours is the only one based on spodumene, as the TSB is the only spodumene belt in the United States. Most of the other U.S. projects will be using raw materials or processes that have not been proven at commercial scale, so there may be technical risk associated with them that Piedmont does not have. We believe that our process will be one of the safest, most cost-efficient operations in the world.
