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. Royal Gold will have the option to earn up to 40% economic interest in the joint venture by investing up to $30 million (inclusive of the initial $5 million investment) prior to October 2018. 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 and development of the Tetlin Properties. The Company has completed five years of exploration efforts on the Tetlin Properties, which has resulted in the discovery of the Peak Zone mineralization within the Chief Danny prospect area on the Tetlin Lease. While no significant field exploration was conducted on the Tetlin Properties in 2014, the Joint Venture Company anticipates spending approximately $5 million in exploration work on the Tetlin Properties during the summer of 2015 and may expand the amount of exploration work in the late Summer of 2015, if drilling results warrant further work. Additionally, the Joint Venture Company acquired 59 new state of Alaska claims consisting of 9,439 acres in the Eagle claim area.
