I find it interesting with all the objections about the Rosemont mine that nothing has been written with factual comparison about actual experiences with the Duval or Pima mines nearby. Overall, have they been beneficial to Arizona or the communities here? Have or are they irreparably damaging the environment in horrible ways? Are they economic boondoggles? Will Rosemont be as bad or worse? If so, why?
