From time to time, the Company may become involved in various lawsuits and legal proceedings, which arise in the ordinary course of business. Litigation is subject to inherent uncertainties, and an adverse result in these or other matters may arise from time to time that may harm business. Except as otherwise identified herein, management is currently not aware of any such legal proceedings or claims that could have, individually or in aggregate, a material adverse effect on our business, financial condition, or operating results.

The principal office location lease expires on November 30, 2027 and the Lab leases expire on February 1, 2026. Consistent with the guidance in ASC 842, The Company has recorded the principal office lease in its consolidated balance sheet as an operating lease.

Financial Assurance

Nevada and other states, as well as federal regulations governing mine operations on federal land, require financial assurance to be provided for the estimated costs of mine reclamation and closure, including groundwater quality protection programs. The Company has satisfied financial assurance requirements using a combination of cash bonds and surety bonds. The amount of financial assurance the Company is required to provide will vary with changes in laws, regulations, reclamation and closure requirements, and cost estimates. At June 30, 2025, the Company’s financial assurance obligations associated with U.S. mine closure and reclamation/restoration cost estimate totaled $0.1 million, for which the Company is legally required to satisfy its financial assurance obligations for its mining properties in Tonopah, Nevada.
