NOTE 5—ASSET RETIREMENT OBLIGATIONS

We estimate asset retirement obligations (“ARO”) for final reclamation based upon detailed engineering calculations of the amount and timing of the future cash spending for a third-party to perform the required work. Spending estimates were escalated for inflation at 2% per year and the estimated cash outflows were then discounted at 4% at December 31, 2020 and 2019.
