I think that a lot of the processes, in general, have parallels among them.
Strange Lake is a truly unique deposit, geologically as well as technically, in that it is related to conventional granite. The research that was done, as well as our research, indicated a very efficient recovery of the metals at high recovery rates, but I think, as has been pointed out, that the critical path is also the separation step. We are producing a high-purity concentrate, and now it's to get the technology to separate the mixed metal concentrates into individual rare earth products.
