The Toronto-based company proposing to build the Rosemont Mine southeast of Tucson says it’s still committed to the project despite continued copper price declines.
Over the past month, copper prices have touched on six-year lows — dating back to the depths of the post-financial-crisis recession — before rising slightly late last week. On Thursday, the price was $2.38 a pound, up from $2.31 earlier in the week.
