Project Cancellation in the Black Hills
On Friday, May 8 2026, Pete Lien & Sons, a Rapid City-based mining company, submitted a letter to the United States Forest Service withdrawing its plan of operations for a proposed graphite drilling project in the Black Hills of South Dakota. The company indicated it will not file a revised plan for the project. The withdrawal follows a temporary restraining order issued on Monday that halted drilling for two weeks and a series of lawsuits filed by Indigenous groups and environmental organizations.
Historical and Legal Context
The Black Hills are considered unceded territory by the Sioux Nations. The 1868 Treaty of Fort Laramie recognized the area as Sioux land, but the U.S. government seized it after gold was discovered. A later Supreme Court decision affirmed that the tribes are owed compensation, a settlement the Sioux have not accepted, maintaining their claim to the region. The area also contains the sacred meadow Pe’Sla, used for ceremonies and buffalo grazing.
Primary Stakeholders
- Pete Lien & Sons – Mining company proposing the graphite drill.
- NDN Collective – Indigenous advocacy organization that coordinated legal action and communicated the withdrawal.
- United States Forest Service – Federal agency that granted the original permit and received the withdrawal letter.
- Nine Sioux-affiliated tribes from South Dakota, North Dakota, and Nebraska – Plaintiffs in a lawsuit alleging violations of the National Historical Preservation Act and the National Environmental Protection Act.
- Environmental groups – Co-plaintiffs arguing the project should not have qualified for a categorical exclusion from environmental review.
Chronology of Key Actions
- Monday (early May 2026) – A temporary restraining order bars drilling for two weeks.
- Thursday, May 7 2026 – Pete Lien & Sons notifies the Forest Service of its intent to withdraw the project plan.
- Friday, May 8 2026 – NDN Collective releases the company’s formal withdrawal letter to the public.
Quantitative Details
- Nine tribes filed the federal lawsuit.
- The restraining order limited drilling activities for a two-week period.
- The project targeted graphite extraction; no production figures were disclosed.
Official Statements & Responses
Pete Lien & Sons communicated, via its letter, that it will not pursue an alternative plan for the graphite operation. NDN Collective described the outcome as a “multi-faceted win” that provides a template for future land-defense actions. The United States Forest Service and Pete Lien & Sons did not respond to requests for comment at the time of reporting.
Opposition and Legal Challenges
Opposition centered on the project’s proximity to Pe’Sla and its potential impact on cultural practices and buffalo grazing. The nine tribes alleged that the Forest Service issued permits without completing required environmental reviews, violating both the National Historical Preservation Act and the National Environmental Protection Act. Additional plaintiffs argued the project should not have qualified for a categorical exclusion, prompting the restraining order.
Significance and Potential Consequences
The cancellation underscores the influence of tribal and environmental advocacy on resource-development decisions in the Black Hills. It may deter similar projects lacking comprehensive environmental assessments and reinforce legal precedents concerning Indigenous cultural sites and unceded lands.
Conflicting Reports & Information Gaps
Both the Forest Service and Pete Lien & Sons declined to provide comment, leaving details of the permit-review process and any internal assessments of the project undisclosed.

Future Developments
The parties indicated that the case will continue to shape litigation strategies concerning land use in the Black Hills. Ongoing tribal claims to the region and potential future mining proposals are expected to be evaluated against the precedent set by this withdrawal.
