> I'm only applying this to modern mining operations like those in US/Canada that follow pollution regs. I am by no means a mining expert, but most of my exposure comes from east-coast US, where a lot of the mines (well...a lot of the mines you hear about - there could a great many very nice mines that I never heard of) have problems with acidic wash off, strip mining, etc. I know SOME of the issues I've listed are impacted by modern environment regs (at least until those get rolled back under the current lawmakers), but I don't know if they all are. Can you expand your point?
