If the proposed purchase of Quadra FNX by Polish KGHM goes ahead, it will mean $3 billion in cash going into the pockets of Quadra investors. I always consider deals like this to be very good for the market over all. Even if only 5% of that goes into the junior explorers/miners, it would mean a big cash injection for the market.
