In short we don't know details yet as they are commercial in confidence.
However we do know a couple of things.
1. They haven't paid a large sum as they didn't have the cash reserves to do so.
2. The Head lease has a royalty payment of 2.5% from the tungsten which will be extinguished. Therefore likely to pay for itself within a few years.
3. Getting control of the whole site is the important part as it removes any major impediments. Therefore it's a major achievement.
4. The quarry is the by product but provides a nice cashflow. It's not the big fish.
I do know one thing.
If you are wrong and the value that is a world class tungsten mine comes through, then you will kick yourself by saying you had millions of shares and sold them way to early.
