Commitments And Contingencies |
Commitments And Contingencies | 7. Commitments and Contingencies ​ The Mt Todd site was not reclaimed by the predecessor owners when the mine closed in 2000. Reclamation obligations associated with this period and prior to Vista’s acquisition in 2006 are presently the responsibility of the Northern Territory, Australia Government (the “NT Government”). At such time as we provide notice to the NT Government that we intend to proceed with development, the Company will then assume these historical rehabilitation liabilities currently stated by the NT Government at A$73 million. ​ Under an agreement with the Jawoyn Association Aboriginal Corporation with respect to Mt Todd, we have agreed to a gross proceeds royalty (“GPR”) ranging between 0.125% and 2.0%, depending on prevailing gold prices and foreign exchange rates, and a 1.0% GPR not tied to gold price or foreign exchange rates. The combined GPR range is 1.125% to 3.0%. ​ Our exploration and development activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. Future expenditures that may be required for compliance with these laws and regulations cannot be predicted. If the Company determines that it is probable that an obligation exists and the amount can be reasonably estimated, a provision for environmental liability would be recorded. This may include reclamation costs attributable to mining claims previously held by the Company should no other responsible or potentially responsible parties be identified. We conduct our operations in a manner designed to minimize effects on the environment and believe our operations comply with applicable laws and regulations in all material respects. During 2022, the Company reviewed the provision for environmental liability for a previously held non-core property and the associated contingent liability and determined that the reclamation costs were neither probable nor could be reasonably estimated. The Company reversed its provision for environmental liability, which resulted in a $240 gain in other income/(loss). ​
