A big part of that was VZ agreeing to pay off the ICSID award. VZ had been fighting and delaying (and continues to do so) paying the $750mil they owe. With GRZ helping to facilitate development of the mine, VZ will pay in full, plus buy the mining data GRZ is holding.
GRZ is not loaning VZ any money. They are facilitating the loans, then will help run the mine. Anyone who has been around long enough should know Doug is going to do everything right to protect his company and shareholders.
Remember, too, both parties are moving forward based on an MOU - a verbal agreement which can be canceled at any time for any reason - so nothing is set in stone.
This could all fall apart this weekend when the MOU expires.
