6 Reduction of royalty in certain cases

Where the Joint Authority is satisfied that, having regard to the rate of royalty determined under section 5 in respect of a mineral of a particular kind, further recovery of that kind of mineral under a mining licence would be uneconomic, the Joint Authority may, by instrument in writing, determine that the royalty in respect of that kind of mineral recovered under that licence shall be at such rate (being a rate lower than the rate determined under that section) as the Joint Authority specifies in respect of such period as the Joint Authority specifies.
