These guys are clowns. Read the second page. There is a good reason why RWD has spent years tinkering with their evaporation sequence.
SO4 is full of excuses for having little idea of what they were doing. KLL has 108KT SOP equivalent ready to go.
Also the plant still hasn't produced a saleable product. Are they capable of producing one product let alone three?

KLL is now the confirmed pick for investors that want a near production WA SOP investment imo. Note I don't hold KLL.
