A coalition of Native American tribes, activists and environmental groups has secured a rare victory in the fight to protect Pe’ Sla, a sacred site in South Dakota's Black Hills, from mineral exploration.
The campaign began after Oglala Lakota scouts discovered that drilling had started at the site. Within days, tribal organisations and environmental groups had mobilised, combining legal action with direct protests and a public campaign. The mining company eventually abandoned its drilling plans.
Pe’ Sla holds deep spiritual significance for the Great Sioux Nation. Tribal communities regard the area as a sacred landscape connected to their history, ceremonies and traditional practices.
The discovery of drilling therefore triggered an immediate response. Two Oglala Lakota scouts had gone into the area after hearing that exploration was expected to begin. They found a newly cut road and a drilling rig operating beyond it.
The drilling had been authorised by the US Forest Service on 27 February. Pete Lien & Sons, a local mining and construction-materials company, was permitted to drill 18 boreholes on national forest land, including several within a protected area around the central meadow at Pe’ Sla.
One of the main objections concerned the way the project had been approved. The Forest Service used a categorical exclusion rather than carrying out a full environmental review.
For tribal communities, the decision was particularly sensitive because the land has been used for prayer and ceremony for generations.
The mineral being sought added another dimension to the dispute. The company was exploring for graphite, a mineral considered important to the clean-energy transition because it is used in electric-vehicle batteries.
That created a difficult conflict between the growing demand for minerals needed for new energy technologies and the protection of Indigenous sacred lands.
Opposition to the drilling came from tribal nations, local officials and members of the public. NDN Collective, the Black Hills Clean Water Alliance and Earthworks took the Forest Service to court, while several tribes filed another lawsuit challenging the project.
But the legal process was moving more slowly than the drilling operation.
After learning that a restraining order had been sought, the mining company accelerated its work. Organisers feared that the company would complete as much drilling as possible before a court could intervene.
On 30 April, activists used a drone to locate the drilling equipment. About 40 people travelled to the site and blocked the access road. They then positioned themselves on the drilling pads to prevent the machinery from operating.
The protest had initially been planned as a one-day action. Instead, organisers decided to remain at the site.
For seven days, demonstrators occupied the drilling pads. Young activists and elders took part, while tribal ceremonies and prayers became an important part of the protest.
The conditions were difficult. Police and private security personnel were present, helicopters flew overhead and temperatures dropped sharply at night. Despite those challenges, the protesters maintained their presence at the site.
The organisers also recognised the importance of controlling the public narrative. When reports described the protesters as dangerous, they used livestreams and their own communications to show what was happening at the site.
Their strategy was not limited to protest. The legal challenge continued at the same time.
On 4 May, a federal judge ordered the drilling to stop. The court found that the plaintiffs were likely to demonstrate that the Forest Service had improperly approved the project.
The protesters nevertheless remained cautious. They did not immediately leave the site because they were concerned that the company might resume drilling after the court order.
Several days later, Pete Lien & Sons informed the Forest Service that it was withdrawing its drilling plan and would not submit another one. The company did not publicly provide a detailed explanation for the decision.
For organisers, the outcome demonstrated the value of combining different forms of pressure.
A lawsuit alone could take too long. A protest alone might be removed by authorities. Public attention alone might not be enough to change a company's plans. At Pe’ Sla, however, the different strategies reinforced each other.
The dispute also highlights a larger issue facing Indigenous communities across the United States.
Demand for critical minerals such as graphite, lithium, copper and nickel is increasing as countries expand electric vehicles and other clean-energy technologies. But some of those resources are located near or within areas that Indigenous communities consider culturally or spiritually important.
For the tribes involved in the Pe’ Sla campaign, the fight was therefore about more than one drilling project. They viewed the effort as part of a broader struggle to protect ancestral lands and preserve Indigenous sovereignty.
The successful campaign offers a rare example of an Indigenous-led movement preventing a mining project from proceeding. It also shows how legal challenges, community organising, direct action and cultural traditions can work together when communities face pressure from extractive industries.
