That's exactly right skinny. With the recent delay issues, whoever wanted to buy would be putting in bids. There has been huge accumulation here from the $1.60-$1.90 level, more so between $1.60 and $1.75ish. RBC is definitely up there with the number of shares bought. Maybe for one of their mid cap funds or resources funds...who knows.
If you look at that link I posted earlier, there has been almost 8 million net shares added in the last 3 months.
