"Of course does not take much time to formalize approval, just the will."
Precisely, and I believe our EA has passed all tests but the will to release it is not there.
And that will is not from bureaucratic administrators but governing politicians, who aqre going if not gone, on holidays.

The will is not there because the Is have not been dotted nor Ts crossed in negotiations with Mattawa.

I suspect the natives want a share of profits but government ( need I also say public like me) who are unwilling to grant it.
