Canada must do much more to promote ethical mining

He suggests that an ethical approach to mining would entail calling into question “the underlying economic and ecological value” of mines in which the grade of ore is so low that its extraction would involve practices ruinous to communities and the environment. In other words, a “sane mining ethic would establish limits on prolonging extraction once the grade reaches an unsustainable level in an area.” Establishing such limits would mean interfering in profit-seeking markets – a prospect that Siegel bleakly calls “unimaginable.”
