Canada-based Kinross Gold is said to be rethinking plans for expansion of its massive open-pit mine at Tasiast, Mauritania, after a strike shut the facility for 10 days this month. Amid the shut-down, rating experts at the Bank of Montreal downgraded Kinross and removed the expansion of the Tasiast mine from production forecasts for the company. Some 1,500 workers, representing 98% of the labor force at the mine, walked off the job Aug. 8, demanding better health coverage and respect for Mauritania's labor code. The conflict seems to have begun when managers demanded the mine remain in operation during the Muslim holy day of Eid al-Fitr. The strike, called by Mauritania's main trade union confederation, the CGTM, was resolved Aug. 19 under terms that were not made public. The International Trade Union Confederation (ITUC), with which the CGTM is affiliated, is demanding "urgent clarification" on the fate of one worker for subcontractor Canary Log, allegedly found dead under "obscure circumstances" near the mine site during the strike.
