Mineral properties consist of original acquisition costs and purchased mineral rights related to the Elk Creek Project.

In addition to the land and mineral rights currently owned by the Company, the property interests of Elk Creek include seven prepaid mineral exploration option-to-purchase agreements which include a pre-determined buyout for permanent ownership of the mineral and/or surface rights. Terms of the agreements require no further significant payments, and the Company may terminate the leases, negotiate lease extensions, or elect to purchase the mineral and/or surface rights any time. Agreements that allow for the purchase of mineral rights contain provisions whereby the landowners would retain a 2% net smelter return.

During the year ended June 30, 2025, the Company completed negotiations with landowners in Nebraska and entered into contract amendments which extended the option periods by approximately five years for option to purchase agreements (“OTP”) covering six parcels of land for project construction and operation which the Company does not already own. The Company recorded an exploration expense for $310 paid for OTP extension payments made and will make periodic payments totaling $93 over the extension period.
