The question you have to ask is, what did CAZ apply for the mining permit and acquire the tenement for? was it for every known mineral in the world (which is not a category) or was it specific? which means that the common law and statute that governs minerals and all things that lie beneath the surface of the earth belong to the state.

CAZ will settle with RIO or a decision that goes in its favour will be appealed by RIO or vice versa and they will have to negotiate a settlement. Never cut and dried.

If RIO holds them out to dry with an appeal or with amended pleadings to bring in new claims and counter claims, they will hold till the market either dries up or costs become too prohibitive for CAZ to do anything about it. RIO controls most mineral markets and governments are powerless to interfere as these are spread accross a wide variety of jurisdictions.

Common sense must prevail.
