Ann: Galan Secures Glencore Agreement For Offtake & Financing, page-105

Bare in mind that stage 1 will be producing 5367 tonnes of LiCl to the tune of over $1m free cashflow per week, or possibly double that if prices remain higher / improve compared to the lower DFS figures. At a sale price of $25k per tonne for example that is over $100m p.a. in free cashflow from stage 1.
Depending on timing of stage 2 completion, that cashflow can make a serious dent in the capex. Then there is the possibility of debt funding, grants etc.
If J.P was able to pull off a non-dilutive deal for stage 1 then stage 2 should be a hell of a lot easier. Worst case they could just run the stage 1 plant for 3-4 years and cover it, so any accelerated option would have to be more attractive than that to make sense.
