RE: KGHM TakeoverThey've said that they're targeting a company with a mine/project in Latin America (see
https://www.bloomberg.com/news/2011-09-06/poland-s-kghm-seeks-to-buy-copper-mine-in-latin-america-ceo-tells-puls.html) , so most likely not Abacus. They've also said the acqusition will account for most of
this year's cap-ex, and they certainly won't need to spend $600 million on Ajax this year.
That said, if they decide to go ahead with Ajax, it would make eminent sense for them to buy Abacus. KGHM seems to quite conservative, though, so they might want to wait until permitting is completed.
