Here's a good example of a gap being filled over a longer time period.
I recall the day CZI took off in 2014. It was up around 400% that day with news that BHP had sold them a great asset in the middle of nowhere.
As IAM a novice and very bad communicator, I would prefer the more experienced here to maybe throw a few comments in about this particular gap.
I always had the feeling it needed to fill, but only because I had heard of gap theory...
Cheers.
