The Financial Post reports in its Tuesday, June 13, edition that two Canadian-listed miners, including the world's largest gold producer, have suffered setbacks at their operations down south, as a Chilean court extended the closure of Lundin Mining's copper mine due to a sinkhole while labour concerns forced Newmont to suspend activity at its gold mine in Mexico. The Post's Naimul Karim writes that an environmental court in Chile on June 8 said operations at Lundin's Alcaparrosa copper mine could remain suspended until a trial linked to a lawsuit filed against the company is completed. The move could "seriously jeopardize" the future of the mine, said Lundin's Chilean subsidiary Minera Ojos del Salado in a statement. It added that it would appeal the court's decision. Meanwhile, Newmont had to suspend operations at its Penasquito mine after its workers went on a strike. The workers' union has demanded a doubling of an annual profit-sharing provision to 20 per cent, Newmont said in a press release. "Newmont remains willing to participate in conciliation meetings to reach a resolution," the company said in a statement. Newmont added that it tried to resolve the dispute prior to the strike.
