Surety bonds

At December 31, 2022, the Company has outstanding surety bonds in the amount of $126.1 million in favor of either the United States Department of the Interior, Bureau of Land Management ("BLM"), or the State of Nevada, Department of Conservation & Natural Resources as financial support for environmental reclamation and exploration permitting. This includes surety bonds for the Lone Tree project and the Ruby Hill property in the amounts of $87.0 million and $22.8 million, respectively. The surety bonds are secured by a $32.9 million deposit and are subject to fees competitively determined in the marketplace. The obligations associated with these instruments are generally related to performance requirements that the Company addresses through its ongoing operations. As specific requirements are met, the BLM and State of Nevada as beneficiary of the instruments, will return the instruments to the issuing entity. As these instruments are associated with operating sites with long-lived assets, they will remain outstanding until closure.
