because they have a mining licence already and they know they have a world class economical resource. So a cheaper and more efficient strategy is do a scoping study after they've already engaged parties to set up the mining op (so costs should be close to actual). Why waste millions messing about with a hypothetical PFS which ends up getting revised continually and is based on loose assumptions, look at PEK and other similar players with cost blow outs and continual updates. Their strategy is speed to production - how can that be a bad thing for shareholders - do you not want profits sooner? To what benefit would delaying / waiting give LIN?

I don't expect you'll be able to give me an answer that follows any logic.
