Mineral Rights and Properties | Mineral Rights and Properties As of December 31, 2025, we had mineral rights in the U.S. states of Texas, Wyoming, South Dakota, Colorado, Arizona and New Mexico. These mineral rights were acquired through asset acquisitions, lease or option agreements. As of December 31, 2025, annual maintenance payments of approximately $2,263 are required to maintain these mineral rights. As of December 31, 2025 the activity of these mineral rights and properties was as follows:
| Amount
Balance, December 31, 2023 | $ | 274,490 |
Depletion capitalized into inventory | (2,568)
Balance, December 31, 2024 | $ | 271,922 |
Additions | 1,244 |
Depletion capitalized into inventory | (7,332) |
Balance, December 31, 2025 | $ | 265,834 |
The Company recorded additions to mineral rights and properties totaling $1,244 and $0 for the years ended December 31, 2025 and 2024, respectively. The additions in 2025 are related to the new asset retirement obligation for Upper Spring Creek. The Company recognized depletion of $7,332 and $2,568 that was capitalized to inventory during the years ended December 31, 2025 and 2024, respectively, utilizing the units-of-production method. Of this amount $2,221 and $482 was included in distributions to non-controlling interest and $1,490 and $1,234 was capitalized into ending inventory as of December 31, 2025 and 2024, respectively. Texas Alta Mesa Project The Alta Mesa Project is located in Brooks County, Texas. In February 2024, the Company completed several transactions under a master transaction agreement (the “MT Agreement”) with Boss Energy. The completion of these transactions resulted in the Company holding a 70% interest in the project while also remaining as the project manager. Boss Energy holds a 30% interest in the project. Refer to Note 8 – Sale of Minority Interest in Alta Mesa for further details. As of December 31, 2025 and 2024, $108,632 and $118,438 was capitalized as Mineral rights and property on the Company’s consolidated balance sheets. Wyoming Gas Hills The Company owns a 100% interest in the Gas Hills Exploration Project located in the historic Gas Hills Uranium District 45 miles east of Riverton, Wyoming. The Gas Hills Project consists of approximately 1,280 surface acres and 12,960 net mineral acres of unpatented lode claims, a State of Wyoming mineral lease, and private mineral leases, within a brownfield site which has experienced extensive development including extraction and mill site production. For a more detailed discussion of the Gas Hills Project see the section titled “Material Properties,” below for this project.. Juniper Ridge The Juniper Ridge Project is an Exploration Stage Property located in Wyoming. The Company owns a 100% interest in the Juniper Ridge Exploration Project located in Carbon Count and consists of approximately 640 surface acres and 3,240 net mineral acres of unpatented lode mining claims and a State of Wyoming mineral lease and is located within a brownfield site which has experienced extensive exploration, development, and mine production. South Dakota Dewey-Burdock The Dewey-Burdock Project is an ISR uranium project located near Edgemont, South Dakota. Notably, the advanced stage Dewey-Burdock Uranium Project (“Dewey-Burdock” or “Dewey-Burdock Project”) in South Dakota has demonstrated ISR resources, including a 2019 Preliminary Economic Assessment (“PEA”) citing robust economics. The Dewey-Burdock Project has its source material license from the U.S. Nuclear Regulatory Commission (“NRC”) and its underground injection permits and aquifer exemption from the US Environmental Protection Agency (“EPA”). On September 2, 2025, the Company announced that the Dewey-Burdock Project had been approved for inclusion in the FAST-41 Program by the U.S. Federal Permitting Improvement Steering Council (“Permitting Council”). This is a component of the implementation of President Trump’s Executive Order on Immediate Measures to Increase American Mineral Production. The Dewey-Burdock Project received its Source and Byproduct Materials License in 2014, from the NRC, now under timely renewal, and will work with the NRC as the lead agency for federal permitting. The Company’s objective is to advance the Dewey-Burdock Project into development and operation utilizing the ISR uranium extraction process. Under the Executive Order, the Permitting Council identifies priority infrastructure and critical mineral projects to receive accelerated permitting review. The addition of the first South Dakota ISR project supports the domestic uranium production focus of the United States. This focus enables the development of essential clean energy, extracted through environmentally responsible ISR technology, to provide affordable, reliable domestic energy. On September 16, 2025, the Company announced that the EPA Environmental Appeals Board (“EAB”) has denied in full a petition for review filed by the Oglala Sioux Tribe, Black Hills Clean Water Alliance, and NDN Collective against the EPA’s issuance of Class III and Class V Underground Injection Control (“UIC”) permits for the Company’s 100%-owned Dewey Burdock Project in South Dakota. The decision allows the Dewey-Burdock Project to advance through federal permitting with the intent to commence state permitting activities in 2025, accelerating the Project towards development ahead of schedule. New Mexico McKinley, Crownpoint and Hosta Butte In April 2025, the Company executed a definitive sale and purchase agreement to sell certain mineral rights and properties that were classified as held for sale and owned by NM Energy Holding Canada Corp. (“NM Energy Canada,”) an enCore subsidiary (the “Verdera Transaction”) that holds the Crownpoint and Hosta Butte projects located in McKinley County, New Mexico to Verdera Energy Corp. (“Verdera”) pursuant to a share purchase agreement, dated March 17, 2025 (the “Share Purchase Agreement”). As a result of the Verdera Transaction, the Company contingently received 50,000,000 Preferred Shares of Verdera. The Preferred Shares provide voting rights related to approval of a “Going Public Transaction”, which is defined as a transaction that results in the common shares of Verdera being listed on a Canadian stock exchange and concurrent registration under the Exchange Act, which the Company has agreed to vote in favor of so long as the Going Public Transaction results in aggregate gross proceeds to Verdera of at least CAD $20 million. In the event that Verdera did not execute the Going Public Transaction by February 23, 2026, the Company would have the right to reacquire NM Energy Canada from Verdera in exchange for transferring all of the contingently received 50,000,000 Preferred Shares of Verdera back. As such, the recognition of the fair value related to the Preferred Shares had no impact to the financial statements as of December 31, 2025 and 2024 as the “Going Public Transaction” related contingencies were not resolved as of such dates. Subsequent to December 31, 2025, Verdera completed its listing on TSX-V and 15,000,000 Preferred Shares were converted into common shares of Verdera, See Note 19 - Subsequent Events for further details
