You can do whatever you want. Validity is another question.
I do note that you only mention Tolga's losers, not the winners. So seems (at least from the outside and I may be wrong) that you have an axe to grind.
Personally, given his past dealings with large players in the resource space and given Canyon have a large resource that needs to build relationships with the big players...well it doesn't seem like such a strange fit.
I also respect the judgement of the Chair and MD. Everyone else they have brought into this project is of a high quality and I expect Tolga will have been brought in for a purpose as well.
I watch with interest and am expecting an eventful 3 to 6 months, especially given this from 'The Bauxite index this morning in reference to Chinese refineries/smelters "domesticore shortage spreads south"
