Thanks for the info dsaul, that helps. I think somewhere I read that Kiewit is connected with Buckskin Mining. Not sure I have the name right. Question, does Doe testing mean DOE validation of CCTC process and as part of DOE validation is commercial viability considered by the DOE? If not, why are DOE tests important? It feels like CCTC is at the end of one journey, and beginning another.
