Yes, the PR was worthless, especially since they already said before the price could be higher because of the rising price of gold. It's like they just wanted to get a PR out, so it may mean they are still not close to the release of the big PR.
But what they are saying seems to mean that the buyer has agreed to give more money if the price of gold rises or that the money for the sale has been converted into gold when it was at a lower price and is now worth more.
If so, could we get the dividend in gold as someone here said before or would it have to be converted in US Dollar?
