"Not necessarily. A resignation of a BM can sit with the chairperson in confidence before an announcement is made, due to extenuating circumstances. However, this is all in speculation. "

Can you cite an example under Ontario Securities Law that supports your statement (or Alberta Securities Law)?  Otherwise your statement sounds very vague and fuzzy.  Securities and Exchange Commision rules don't apply here (SEC), only Canadian Law.

The facts are, RVX has made two BoD announcements recently:

(1) CALGARY, Alberta, Dec. 11, 2019 (GLOBE NEWSWIRE) -- Resverlogix Corp. (“Resverlogix” or the "Company") (TSX: RVX) today announced that Dr. Eldon Smith has stepped down from the Board of Directors, effective today. ; and

(2) CALGARY, Alberta, Dec. 20, 2019 (GLOBE NEWSWIRE) -- Resverlogix Corp. (“Resverlogix” or the "Company") (TSX: RVX) today announced that Mr. Dicky To has been appointed to the Company’s Board of Directors. His appointment is effective as of December 19, 2019.

That is how RVX would treat any change in its BoD...timely disclosure.  There would have to be very compelling circumstanes to deviate from their established practice, and I'm not aware of any that would support your argument. 

I'm sorry for going along on this side show.
