11. Asset Retirement Obligations
Asset retirement obligations relate to the Lost Creek mine and Shirley Basin project and are equal to the current estimated reclamation cost escalated at inflation rates ranging from 0.74% to 5.20% and then discounted at credit adjusted risk-free rates ranging from 0.33% to 9.61%. Current estimated reclamation costs include costs of closure, reclamation, demolition and stabilization of the wellfields, processing plants, infrastructure, aquifer restoration, waste dumps, and ongoing post-closure environmental monitoring and maintenance costs. The schedule of payments required to settle the future reclamation extends through 2033.
The present value of the estimated future closure estimate is presented in the following table.
