Thanks for that. Will do more research to see if I can increase my understanding on technical grade. Never really thought about it until I was reading up on Greenbushes in a bit more depth the other day. From the looks of it PLS has thought about the question (tapping into the chemical and technical grade market) as well and no wonder it has a sound NPV to it (I recall the returns it was forecasting from its Definitive Feasibility Study in 2016 were very very solid too). Thanks again.
