ARO is primarily comprised of estimated reclamation costs related to ISR projects in South Texas. On December 31, 2020, the Company closed the sale of its US uranium assets to enCore Energy. With the sale, enCore assumed all liabilities for the purchased subsidiaries, including the $6 million in asset retirement obligations for the south Texas uranium projects. At December 31, 2020, there is no ARO recorded for the Coosa Graphite Deposit as there has been only minimal environmental disturbance due to exploration which has since been reclaimed.
