They are playing a cat and mouse game, biggest risk to MUS now they have got to first auction is a lowball takeover so screaming to the world they have 150M of rubies to sell for months in advance is the last thing they are going to do, if indeed that is what they have. Plus the ASX does not allow forward looking statements so all that blah blah blah as well.
Also, in order to protect the downstream supply chain they will make very little (read none) effort to enable a punter buying his wife a 3 caret ruby ring to ever know what the cost of the rough stone was, or the cut stone prior to getting to the setter.
It is just the world of the gem supply chain and no amount of questions you ask is going to change that.
Get over it and buy in or move on.
