The Tetlin Lease has a ten year term beginning July 2008 with an option to renew for an additional ten years, or so long as the Company initiates and continues conducting mining operations on the Tetlin Lease. Originally, the Tetlin Lease allowed the Company to only renew 50% of the acreage, but in December 2012, the Company paid the Tetlin Village Council $200,000 in exchange for removing this 50% restriction. The Joint Venture Company is now able to renew its entire lease, consisting of 675,000, acres in July 2018.
