Early solid buying

I wish I knew what was going on here.

There has been very good buying in recent days at 1.90 and continues early today with the 1.90 bid constantly reloaded.

Could this be a group buying in to get a holding in B2Gold post merger, or could it be a separate party looking to accumulate PIR stock for other means?

Only mentioning it now as the early high volume seems a little out of character with no big price increase in BTO overnight.
