Ann: September 2020 Quarterly Report, page-5

Another interesting thing to note is that we are tracking well towards the goal of free cash flow of 70-90m/ year. Based on the sale revenue of 30m ($120 annualised),capex of 7.5 (30m annualised) and assuming additional annual corporate costs of 15m/year, we arrive at a FCF of $75m. Applying a conservative multiple of 10 should get us to 750mn ( 50 cents/share).

This doesn't account for the planned expansions and upside to commodity prices. Let me know if I have missed anything.
