The quality of the graphite is quite high. We were doing our own bench-scale modeling while I was there. We had crushers and grinders. We put material in and pulled it out. Just at the bench scale, without any fancy laboratory equipment or advanced separation, we were getting about 14% graphite concentrations out of rock samples that I picked up off the ground. It has immense volumes, very significant qualities and nice grades. The next big issues for graphite are who the customers will be, where this graphite will go and what people will do with it. That's what goes into the secret sauce of a graphite play."
