RE:RE:RE:RE:Copper Spot Price LinkNot sure what migrant laborers at a pork processor has to do with a struggling Nevada copper minor, but I see one problem with Tyson's strategy, if it is fact real: it's illegal under U.S. law to employ people without legal immigration status and a proper work visa. Although it's not uncommon for migrant laborers to acquire fake Social Security numbers, and for employers to not ask questions, the practice is illegal and subject to prosecution.
