If you don't know why mints aren't happening you didn't read carefully when it happens. When the conditions are met it will happen.
It will happen when price grows over the production price, so the PP can further grow and there is a need to create new Xaurums.
You all should read the Minting rules at xaurum.org

Best regards
Until now the mints happened even if the market price was below the production price. When after the mint the production price stayed the same, the mint should not have happen, or what?
If you are correct then I don't see logic in this. Lets say, the team has tens of millions of euro prepared for the mint and they don't do it because the market price is low. And the market price is low because there are no mints... Do you see a chicken/egg problem? What should increase the price if not mints? Market buy is to weak to do it, or it has only short term influence.
As I understood, the mints are not used only to produce new coins and buy gold, but also to increase the price if it is below the market price. That's why they introduced the 30% market buy rule when making mints. What's the point of the 30%, if the market price is above the production price. Then this is contradictory... There would be no need for 30% rule, if mints would happen only when the market price is above production price. Please explain me this, if you really understand it.
