Ann: Sinclair Mine Complete, First Caesium Shipment Scheduled, page-53

I did a few calculations on spodumene to check my assumptions as to the share of the value of the final product (caesium formate) we should capture.  According to my calculations by molecular weights, it takes 10.39 tonnes of spoumene concentrate at 6% Cs2O to produce a tonne of lithium hydroxide, so on PLS published figures, they are capturing about 75% of the value of the final product.  This is the assumption I made in my earlier post, so it is confirmation of one figure I have used.  The great uncertainty now is the market prive of caesium formate.
