Contract price indeed, but what is it going to be?
Lets be real here....I can't imagine that Ganfeng is financing some $250million capex for free, just to be able to buy at market price Spodumene from us right?
A likely and desired pricing mechanism would be if price would be set al prevailing quarterly market contract trend, less amortised $250million initial capex, for the duration of the mine life.....even accounting for some interest repayments.
I can't see Ganfeng participation in opex costs during production, it wont make sense in accounting terms, but I am trying to understand where it fits the 50% participation of Ganfeng in the project....?
We know Goulamina has a capex payback of 1 year at Spod6% price under $1000/t, so in reality Ganfeng capex financing can be paied off in few months.
Is also understandable that Ganfeng will want to get a slice of the cake above repayments of its financing, but if that is the case, how much?
I suppose all will be revealed when times come.
