Sounds good, like you know a little 'bout down under law.
But again, that's about it.
As you still fail to reconcile the ownership of minerals by the state with an explorers rights to the same bounty.
As such, the little Tazzy Government took steps to eliminate the threat of ‘sovereign risk’ by an explorer with measures in the Mineral Resources Development Act of 1995
Foremost, being an easy application process. If the company by happenschance actually stumbles upon a new find of gold or coal/coal seam gas for that matter, especially in economic amounts, I can almost guarantee you its not going to be exploited by some other company even if they held the prospective license for that mineral.
Of course, that's just my opinion.
