50,000 to 400,000 tonnes ... ... in my estimation ... Larry could throw out a suggestion like that at this point ... because he has seen the 'final' draft flow sheet and mine plan ... and the scalibilty issue is a non-issue. Not only is it scaleable from the test plant design ... it is scaleable from a mine plan perspective ... how big do you want to go.
I think the talk of off-take is a bit premature ... you build the cart ... then attach the horse to it ... you round up the horses as you move along the build.
The prefeasibility study is a huge milestone ... and as I say in the opening line ... Larry's right there with scalibility .. in my view.
