An ongoing dispute over ownership stakes in Barrick’s operation in Mali has led to the arrest of mining officials, the government’s gold seizure and the company’s shutdown of its mine.

Mali’s military government has started seizing gold stocks of the Canadian mining company Barrick as part of a legal battle over the share of revenue owed to the West African state, according to an internal Barrick letter seen by The Associated Press.

Mali’s military junta started executing an interim order to seize gold at a mine run by Barrick Gold Corp., escalating a dispute over the West African government’s share of revenues from the project.
