The Company was provided notice by Royalty Consolidation Company, LLC, a private company controlled by Waterton Precious Metals Fund II Cayman, LP ("Waterton") of the sale of 100% of its existing royalty interests in the Nevada Projects to a wholly-owned subsidiary of Franco-Nevada Corporation ("Franco-Nevada").
