The Mongolian government holds a 34% stake in the mine and Turquoise Hill owns 66%. Exchanging the government's stake for "a markedly higher royalty (cash flowing immediately) would be in the best interest of all stakeholders," Wowkodaw said. Turquoise Hill said it was committed to engaging immediately with the government and Rio Tinto to address the development plan and revisit the sharing of economic benefits. The companies have sunk $11 billion into the mine since 2010, Rio said in a separate statement to Reuters, adding it "remains open" to increasing benefits to all shareholders.
