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 we initiate and continue conducting mining operations on the Tetlin Lease. Originally, the Tetlin Lease allowed us to only renew 50% of the acreage, but in December 2012, we paid the Tetlin Village Council $200,000 in exchange for removing this 50% restriction. We are now able to renew all 675,000 acres in 2018.
