Ann: PFS confirms potential low cost lithium carbonate producer, page-37

Miro, I guess it would be fair to use the whole sentence from PFS:

'A trade‐off study was completed in November 2016 comparing the operating and capital costs of the
conventional sodium‐sulphate roast and the L‐Max process. It was concluded that conventional
roasting technology would deliver high lithium recoveries with a lower operating cost, lower technical risk, less impurity removal, and be less dependent on potassium by‐product credits. The Company has selected the sodium‐sulphate roasting option as the preferred method of lithium extraction for the PFS.'

The statement is about "operating costs" and not about overall production costs - they do not say that roasting is overally not higher.
But the overall produsction price was obviously not the sole factor for choosing the technology for PFS (technical risk etc. - as stated above,) - maybe it was also wanted by those potential strategic partners - that they mentioned in PFS.
The next week is an interview with KC - so maybe he brings more light also on this.

However, as I remember the last interviews with KC at the second half of 2016 - he was  always cautious - and talking about "lowest production costs quartile" and that the sodium-sulphate roasting option is in the play as well as L-Max.
Nobody adressed it much that time (obviously because the SP was rising, isnt it?)
