I'm going to speculate a bit here. Is it possible, rumour of this agreement was already out, back when the volume and price spiked about 3-4 weeks ago? Something had to trigger that kind of activity. It doesn't happen in a stock with little to no heartbeat. Now, they finally confirm the agreement and RBC opens Friday with a 263k block.

If so, "could" there already be some surprize revs from this. They would be a smaller day to day order flow as equipment is sold and would not get a PR each time but might add up over time. Maybe a spark!
