Hoping it is good news, and not an issue they have found that delays the DFS. Monday it is then.
Good news would be - higher grade of Li20 product, easier ability to recover tin/tantulum in DMS, higher recovery. And even better that had a halt today if news is good. Quietly confident it is likely to be good news given the amount of METs done to date here.
Bad news would be - recovery rate in DMS stage reduced due to mica/impurities etc etc as DMS stage doesn't deal with impurities (floatation stage does though).
