RE:RE:WHY NOT... The bulk tailings storage facility will be required to be lined which is not currently proposed. That means full water retention with seepage collection wells. The tailings facility will be required to be redesigned with static and pseudo-static analysis requiring potentially a much larger embankment. $$$$$$.
This non-project is a water management, treatment, discharge and post-mining nightmare.
Its not economic per the existing "smaller" mine plan. For that matter its dead all the way around.
