@tomboy In response to the first part of this post of yours.....
As I outlined in my first post in this thread - it could quite simply be BMM selling to their related entity GMM or Metals Acquisitions Corp and doing it on market to provide everyone with full transparency. It works for BMM because they can justify the price for such a large parcel being sold at a profit to them in a cross trade (accepting a lower price for a large trade - happens all the time). It also works for the other party as they quickly get their hands on a large parcel without disrupting the market as they would cause price movement on such large volumes in ordinary trade and great a "20% threshold" problem for their broader group.
So, in the final wash, it may be a whole lot of nothing.....just re-shuffling the deck of cards. Beneficial/effective ownership of POS, at the top end of the share register, remains unchanged.
