Glencore Xstrata announced that it would suspend operations at its Falcondo nickel mine in the Dominican Republic due to falling nickel prices.
The announcement came a day after legislators created a national park on the outskirts of the mine, although the company said its decision was not related to environmental pressures.
A spokesman for the Switzerland-based company told Reuters that the mine will be shuttered temporarily for up to three years resulting in the loss of up to 1,000 jobs.
The ferronickel mine in Loma Miranda about 97 km (60 miles) north of the capital Santo Domingo has been the focus of environmental protests.
The company's plans to expand the mine received a setback earlier this year when the United Nations Development Program rejected an environmental impact study as "incomplete.”
