In my opinion senior mining co execs are mainly motivated by performance rights, they have the largest returns. Now, what if (just what if) they became aware they may not receive them for whatever reason e.g. redundancy because of a take over, would they stick around? Just a what if IMHO. Also, if someone like NST took them over why would they need EAR CxOs when the jobs would be done by NST CxOs? Of course this may not happen. Just idle speculation on my part trying to find an explanation LoL
