dr wolf martinick, o'dea and ward

Im interested in credentials of the three principals of EZE:
W G Martinick (Executive Chairman)
G R ODea
D H Ward

Im finding it very difficult to make a tangible assessment as to the strengths/weaknesses of these three guys. Dr Martinick has obviously been around for a while and has some strong industry ties. He has several other resources industry directorships; Azure Minerals and Sun Resources to name two. That said I cant really pin point anything tangible that he has personally achieved in growing and realising significant value for shareholders in this, or other companies...same for the other two.
Very important as the strategic future of EZE now largely sits in the hands of Dr Martinick. Keen to assess just how well he and the other two guys rate as potential achievers.
Does anyone out there know enough of the achievements (or otherwise) of these guys to comment? Cheers Muzz
