I have a questions regarding the development of stage 2.

Doesn't development of stage 2 actually affect stage 1 production?
So when we are in production in stage 1, I do not think that we are at 2mtpa right from the start, correct me if I am wrong? So ramping up might take some time. And while this takes time there is still development of stage 2 on the same production line? And what if the company announces stage 3 with let's say 8mtpa.
This will then affect the production again.

That would also mean that EBITA will rise slowly and also the share price. And we need be at full production in 2020 when all the other juniors are entering market. Maybe at this point we should have already bought into other juniors to strengthen our market position.

Or am I missing something and this will all be simultaneously? Also regarding the off-take agreements. The companies actually want their offtake amount in on year I guess.

Do you know how the expansion exactly works?
