Greenland's Kvanefjeld site is rich in rare-earth minerals and uranium, with a proposed open-pit mine worth $7.5bn.Local concerns about radioactive waste contamination led to Greenland banning uranium mining in 2021.The mining company has sued Greenland for $11.5bn, claiming expropriation and demanding compensation.The case is in investor-state dispute settlement (ISDS), a provision being used more to challenge environmental laws.Litigation finance investors like Burford Capital fund cases like this, seeking financial benefits if successful.Greenland is determined to resist pressure to restart mining, despite economic interests and investor backing.The high-stakes arbitration case, with ETM seeking compensation, could impact Greenland's future and mining industry.Community opinions in Narsaq are divided, with concerns about environmental impact and risks if the mine proceeds.The potential threats from mining activities include water contamination, chemical use, and disruptions to local ecosystems.The outcome of the arbitration could significantly influence the balance between economic development and environmental protection in Greenland.
