There were 3 pages of Prelim Financial model data used in the global roadshow earlier in the yr, and reasons for DFS delay.
There is a great deal of information availiable already and MPS have also done a pretty good job with their fin modeling.
If people want/need to wait for a DFS for 'clarity' then that's fine. With the mine build underway and strong fin support in place already, I don't think the waters at all muddy.
