we see here the outlook of the demand for HPA and the supply side will suffer a tremendous lack of HPA with at least 99,99% purity.
And to fix a value for the future you have to regard the costs and profit.
My approach
getting in a JV with 50% 
considering the market price of 24000 USD per tonne HPA
making a bank credit with 100 million
fixture point for 8000t with ramp up end of 2022.
paying back credit facility till end of 2024.
Afterwards having a profit after tax for at least 50 Million USD
300 Million shares as bast to this point
you can get a dividend with 15 cent US per share.
12 Million AUD market cap overvalued. Funny statement
