Nexus Uranium Corp. announced that it completed its plan of arrangement to acquire Basin Uranium Corp. on September 16, 2025, consolidating the U.S. portfolio under Nexus and continuing permitting at the Chord Project through Clean Nuclear Energy Corp (CNEC).
The Chord project, which is composed of 3,677 acres east of the Dewey-Burdock project in the Craven Canyon area. This area had a lot of exploration drilling in the 1970s and is a world-class cultural resources site. Union Carbide Corp. started mining in Craven Canyon without getting a state mining permit in 1979 and was stopped by legal action by the Black Hills Alliance (BHA), a regional nonprofit group. This mining was stopped because a local citizen noticed the movement of large equipment into the area and called the BHA. Now, we must move fast to protect this sacred landscape.

The project lies in close proximity to Craven Canyon, a critical historic and cultural site of importance to Indigenous and ranching communities. Portions of Craven Canyon are on the National Register of Historic Places. A federal mineral claims withdrawal protects portions of the canyon from mining, as does a state designation, but CNEC wants to explore there anyway. An archaeologist who studied the site has said that the Nexus/CNEC project drilling would be heard and in a sight line from those cultural and historic sites, potentially disturbing those studying or praying there.
The state public lands proposal calls for fifty drill pads and lies less than a mile from Craven Canyon. The federal lands proposal is a smaller project, with seventeen drill pads. However, it lies even closer to Craven Canyon—surrounding the mineral withdrawal area at the canyon on 3 sides.
In their Plan of Operations (application to the Forest Service), CNEC outlines two months of on-site activity, with 1-2 drilling shifts, 5-7 days/week. After-dark drilling will be accompanied by generator-powered “light plants” to illuminate the operation.
CNEC offers that the project’s “[v]isual impacts will be minimized by selecting drill sites that are not visible from paved roads or permanent structures,” which don’t actually exist in the immediate area. Their plan also includes trucking in municipal water for drilling from Edgemont or Hot Springs – barring that, they will use “readily-permitted sources” on US Forest Service (USFS) land.
The Forest Service appears to be preparing a “Categorical Exclusion” from environmental review of the project areas on federal land. This would allow the project to go forward with no further environmental review, despite its close proximity to an immensely significant historic, archaeological, and cultural site.
The Plan of Operations for the proposed exploration drilling on federal lands is linked here October Jinx POO. The application for the State’s permission to drill is at the start of the document. The federal Plan of Operations starts on page 25.
Currently, there is no provision in state law for tribal agencies (such as Tribal Historic Preservation Officers) to review or provide input on the application. Tribal leaders, area ranching and urban residents, archeologists, and Forest Service staff have fought to protect this area for many decades.
Please stay alert and watch this site and our social media for updates. We will need everyone to take action as CNEC’s requests for permission to drill in this special and unique area.
