A couple of notes ...
1. this ex BSE October 2012 when first mooted ... https://www.baseresources.com.au/wp-content/files/121026_Local_Equity_Participation_Regulations.pdf ... I recall the price trashing BSE took when first published.
2. if I have managed to find the right document and my legalese is somewhere near useful, per clause 6(4) of http://www.mining.go.ke/index.php/r...4-mining-state-participation-regulations-2017 ... "...The State's right to a free carried interest shall not apply to any right that has been granted to a holder of a mining licence, to mine a mineral before the coming into force of the Act...."
having said the above, my hunch is be alert, not afraid!
Have a great day ...
