DSO is a smart move to keep the funds rolling in.
tbh I anticipate delays and some cost blow outs on the commissioning/construction of the smelter/s. You have to accept these possibilities when working in certain jurisdictions.
If they are up and running by the middle of next year I would consider that a good achievement.
Eitherway, as mentioned above if the DSO approval comes in the potential cash flow from this demands a m/c closer to 70-80 mill with a significant discount for risk factored in.
Still assumptions on the above figure as we need to know more about local tax rates etc as the company has only provided a net operating margin.
Still early days but reason for optimism
