In my view,KPIs are the last derisking for this project, Corbonate to LHM process tech is already proven, although that conversion result will be extremely important I think it's safe to say based off KPI prelim results there is no worry on achieving battery grade. This is why I am so excited for KPI's. PFS will make sense, funding will come, plant will be built, 120 tons will be produced. Are we really that's close!!!
