Copper-Nickel Studies and Non-ferrous Mining
Given all this interest in copper-nickel mining exploration at the time, the EQC adopted a resolution in 1974 requiring an adequate regional study examining environmental, social, and economic impacts of non-ferrous mining before the acceptance of any environmental impact studies. This resolution led to the Minnesota Regional Copper-Nickel ...
