The Joint Venture Company is managed according to a Limited Liability Company Agreement between subsidiaries of Royal Gold and the Company . At the Closing, Royal Gold made an initial investment of $5 million to fund exploration activity. The initial $5 million does not give Royal Gold an equity stake in the Joint Venture Company.

Therefore, at Closing, Royal Gold's percentage interest in the Joint Venture Company equaled 0% and the Company's percentage interest in the Joint Venture Company equaled 100%. The proceeds of Royal Gold’s investment will be used by the Joint Venture Company for additional exploration of the Tetlin Property. Royal Gold will initially serve as the Manager of the Joint Venture Company and will manage, direct, and control operations of the Joint Venture Company. The Company has completed five years of exploration efforts on the Tetlin Property, which has resulted in the discovery of the Peak Zone mineralization within the Chief Danny prospect area on the Tetlin Lease. The Joint Venture Company initiated a Summer 2015 exploration program and anticipates spending approximately $5 million in exploration work on the Tetlin Property. Additionally, the Joint Venture Company acquired 59 new state of Alaska claims consisting of 9,439 acres in the Eagle claim area.
