Your absolutely right, a monumental material NR such as a $33million BFS, will be a stock halt by IIROC! As far as a Monday release...probably 90% of good material news is released on Mondays...not so good news Fridays.
I have mentioned Monday June 26th several times, mid January was probably the first time. At that time was for the release of the BFS, not just the important numbers.
I used a Monday, because in my opinion most very important (positive) releases occur early on Monday's. Opposite late on Friday's for negative releases.
