If a company should acquire another company, it would have to do due diligence before acquiring that company. Because there might be some kind of track record going back 20, 30, 40, or 50 years, when practices that we now find abhorrent and unacceptable in 2009.... If we go back 50 years, with the best science and the best understanding of what was happening with regard to exploration 50 years ago, those practices are completely unacceptable at this point. Again, we've opened up yet another gigantic hole to drive some kind of challenge through for any kind of mining activity that has any kind of history other than what the standards are in 2009.
