as i've pointed out a filing ca 2017 noted that zn exec management placed restrictions on their selling stock
(beginning ca may 17- a few weeks before spudding mj1-they likely did this to prevent undue stock speculation by speculators-which can send stocks in crazy up and eventually down spirals)

and probably buying stock (outside of automatic options programs which are part of their pay to reserve/save zn on cash)

i've also noted that stock options or stock obtained via those options has fallen in worth just like everybody elses stock

it has been pointed out the % fall in longs stock pps -well, that same % fall in stock applies to the stock obtained via stock options as part of exec pay

since the execs were not allowed to sell such stock(victor gifted some) and such options/stock were priced at then market value,the executive pay for those years was considerably less than the figures bandied by some

and cash pay for those years was ca only 250k

but we do know chair/ceo john brown spent a large amount of his money over the years on zn's projects
