Ann: Updated PFS Confirms Strong Economics of Sorby Hills, page-25

I share your frustration, but it's not as bad as it seems from those raw numbers:

686,000,000 total placed (using your numbers)
approx 300m went to 3 shareholders who are over 5% and aren't selling
another 50m yesterday and today and lot more traded since the placement
and surely some of the balance are invested for a better return than just getting their money back..especially given PMY is worth $8m and their mine is now worth $180m with a lot more to come..?

Lead, sadly, isn't sexy but a mine is a mine and if G1A is anything to go by there are people that are interested in lead, so eventually greed will overcome. Otherwise eventually some lazy mining exec will just lob a bid for the lot and save himself the drama of having to find something of this scale and at this stage of development.
