Very difficult for me to say Baba as I am not intimately familiar with the discussions that must be occuring between ECU management and the supplier for ECU to broach this subject in today's press release. I would guess it could be anywhere from 6-12 weeks if they decide to go for it and the firm selected with be the limiting factor as always, not the company.
Let us hope that they don't use the same company that is/was preparing the scoping study for the new mill options.
