"Ken's previous time on the Company's Board has given him a good understanding of the rare earth sector and an appreciation of the opportunities that the Bear Lodge Project and our innovative separation and recovery technology represent. That is what makes him the perfect person to lead the Company in its next phase of development," stated Gerald Grandey, Chairman of the Board of Directors of the Company. "With his strong background in mineral development, he understands the steps that will be needed to get the Bear Lodge Project into production. The relationships he has built over the years with different governmental leaders will ensure the Company continues to align its efforts with the needs of the nation. We look forward to Ken using his demonstrated leadership skills in shepherding the Company towards its goal of becoming the cornerstone of a secure, domestic rare earth supply chain."
