The document is there to be read, your concerns on one director may be valid.
36 cents is showing as current open, maybe time to offload if you are uncomfortable.
But i think this set up is solely for a M&A potential as our outlined in the research paper as follows;
"given the fact that Vale requires access to the Ponte Verde site to fully realise their neighbouring resource, we believe there is a significant possiblility that Vale will attempt to acquire the Ponte Verde project rather than cohabitate with SFZ."
The wording "significant possibility" suggests to me that insiders may have stated that is an aim of the company.
Not to say that Vale will oblige, but a $80mil offer from vale is small change for them.
Secondly the 36 cent options are not exercisable until the 3 performance hurdles are met and that SFZ has traded at 5day VWAP of 0.50 or more.
