hey campesino.. waddayu tink dere.. isnidat duh fisch farmz are more of a problemo fer dah environmento dan da minez? I dinna think that doublestar needs doubling down just yet.. acid run off can be calculated, impounded and nowadays with better carbon systemos, systematically "mined" for their run off water. we no longer need electrolytes of high or low ph to collect by faraday principles the free metal ions.. active aerogel carbon dep works on distilled water.... or the tailings can be in the case of higher grade systems, dried by vacuuming and layered with limestone. In the case of lower grade, you don't have to worry. Waste rock should be below 0.05% copper anyay in low grade ops. That won't cause fish-killing cu values in water with run off or high Ph. Fer instance: Stikine Salmon are tolerant of very high (+20PPM) copper values, that would probably kill Ontario trout. The Kerr Addison Mine had problems with copper in mine tailings run off water. Guidelines were to be below 20 PPM. The solution was dilution. Add more water, not less. Unless we are dealing with very stagnant water or lakes, the stuff gets flushed fast, there is no concentration. Despite the high grade copper in the Stikine from natural sources, the vast dilution of this very powerful high volume river would not allow much harm from the very slow run off of a waste dump. It is ironic indeed that Windy Craggy was turned down by the over envi NDP way back when, where it was proven that if the entire waste dump that they proposed, if it had disintregated to solution in 5 years would not have raised the Stikine's already high copper values by only 5 PPM. And it would have taken the dump 200+ years to leach in copper with the size of rock they were to put behind clay berms. The argument was "what if they had a slide into the river.." oh the horror.. 10,000 tons of rock in a river that puts 10,000 cubic feet per second past any given point.. I don't see it picking up much pollution, do you? And all the greater irony exists that if the government were crying out for power for to add generating capacity to the Sierra Club's collection of new electric powered SUV's, the idea to put a dam across the river would be a no-brainer. We need cheap power. That is a large lobby, which has and will overpower the better sense of a reasonable assessment of environmental damage of these beasts.. (they ruin for all time any migratory fish domain...... Ah so it goes the common sense of man, broken in the dust again ... Few if any oil sands areas, or gas drilling projects get turned down for environmental reasons.. If copper were 5 dollars a lb., this might start to change.. EC<:-}
