You've got to work backwards from the development cost, Bikida.
If it were to cost $200m to build the mine, SQM give KDR $30m and spend $80m on the mine, so there's $90m left to fund.
That means KDR and SQM both have to put up $45m to finish the mine.
KDR were carried to that point, for a benefit of $70m
