If you keep the perspective that it could be Newmont or Glencore or any other of a dozen multi-billion-dollar-budget majors, looking for billion-dollar-plus deals, any trading fees would amount to a relatively microscopic cost.
The way this buyer entered like a bull in a china shop (10-15X last spike's volume) smells of a multi-billion dollar acquisition budget. The bullying and control I observed in the market was completely unapologetic and executed without rest, with obviously pre-programmed trading with patterns of violently swirling shares going back and forth, trying to simulate, imo, a mob of many CUU shareholders selling millions of shares.
From what I saw the volume of "fake 'frisbee' trades" to real trades could easily be 50 to 1.
