Brazil's Vale agrees to pay workers as it exits Argentina mine SAO PAULO (Reuters) - Brazilian mining giant Vale SA (VALE5.SA) will pay two and a half months' salary to workers in Argentina as part of an agreement signed on Friday allowing the miner to exit the $6 billion Rio Colorado potash project. The payments will go to about 4,900 subcontractors, a spokeswoman said on Saturday, declining to give further details on the cost of the accord. The agreement could put an end to months of uncertainty for Vale, which suspended work on the fertilizer project in December and announced its intention to pull out in March. Since its decision to exit, Vale and Argentina's government have been at loggerheads over the fate of workers at the site.
