accumulator at work

I had not noticed this before on this stock but on Friday a bot looked to be well and truely at work accumulating. On top of this huge volume of 3.8M last night in Canada and a close there of $3.61. All in all a solid gain for OGC over the week in an anemic week for gold.
Up till now I think this stock has flown under the radar screen for the most part. It rarely gets a mention in broader gold forums or discussions re takeover targets in the sector notwithstanding a nice mix of (now extended) production in NZ and exploration upside in the Philippines. Seems to me it may have caught someone's attention.
