From an operational/marketability point of view that is one of the biggest risks, they were already at the lower end of zinc content and pushing for higher recoveries is likely to drop the con grade.
I’d say that while the conc market is tightening and they can place the material in China then the smelters may still be keen to take it but once Antamina and other other large South American mines are back in production then it remains to be seen if they can still place con that is lower grade than present (as they plan to push the recoveries)
They may put a new slide in their next preso that their concentrate is self smelting!!
