Property Acquisitions In connection with the development of the Elk Creek Project, ECRC, an indirect majority-owned subsidiary of the Company, acquired additional land and associated mineral rights in Johnson County, Nebraska, as described below. August Property Purchases On August 1, 2025, ECRC closed its options to purchase three parcels of land consisting of (i) an 80-acre parcel of surface rights and (ii) two smaller parcels totaling approximately 1.66 acres that included both surface rights and associated mineral rights. The total purchase price was approximately $2,699, including $35 of indirect costs. Of this amount, $2,650 was allocated to land and $49 was allocated to mineral properties. September Property Purchases On September 30, 2025, ECRC closed on its options to purchase two additional parcels of land consisting of (i) a 105.77-acre parcel and (ii) a 220-acre parcel, each including both surface rights and associated mineral rights (the "September Property Purchases"). The total purchase price was approximately $11,325, including $29 of indirect costs. Of this amount, $2,263 was allocated to land and $9,062 was allocated to mineral properties. November Property Purchase On November 7, 2025, ECRC acquired a 40-acre parcel of land and associated mineral rights located within the one-square-mile section that comprises the Elk Creek Project area. The acquisition was completed through (i) the transfer of surface rights to a separate 40-acre tract previously acquired as part of the September Property Purchases, (ii) cash consideration of $500 for the mineral rights, and (iii) the grant of a 2% net smelter return ("NSR") royalty on the acquired parcel. The surface-rights exchange involved parcels of substantially identical value, resulting in no gain or loss recognized. The total purchase price was $551, including $51 of indirect costs, with $531 allocated to mineral properties and $20 allocated to land. Construction in Progress Construction in progress consists of costs incurred for the development of the mine portal and related infrastructure at the Elk Creek Project. |
