Glencore announced on Wednesday, April 15, the detention at Lusaka airport of one of its executives, Nathan Bullock, the managing director of its Zambian subsidiary Mopani Copper Mines. Earlier, on April 8, Mopani Copper Mines had decided to suspend its mining operations due to the coronavirus health crisis. This decision is now being challenged by the Zambian Mining Licensing Committee. In a letter sent on 14 April to Nathan Bullock, Bullock criticised the company for ceasing mining operations without giving « sufficient notice to the government » and giving it seven days to justify its decision or risk having its licence revoked.
