RE:89 cents Being a director is typically speaking (or at least in an ideal situation) not a particularly financially lucrative position. To quote Buffet, board compensation should never be a determining factor in terms of whether members stay on the board. Basically that no one who needs to income from being a director should allowed to be a director. One of the directors who left it says did so to spend more time on his accounting firm, what is likely a much more financialy lucratice opportunity. Another board member who left is the COO, which makes perfect sense as they are now building out their operations. No idea what the third person's deal was but I don't see any of it as a cause for concern.
A quick google search pulled up the AGM from Sept 2020 with the following to do with board compensation.
"While the Company has been in a period of change and growth, no compensation was paid to the directors with respect to their respective roles as directors of the Company up to and including April 30th, 2020 (other than stock options). It is anticipated that directors will begin to receive cash compensation once the Company begins to generate revenues. (Those directors who received compensation during the year ended April 30, 2020 received such compensation for services other than the services of a director.)"
