thirsty this is a big play but a long term one. I get the feeling people are buying up big for quick profits but I think better to put in lazy cash, accumulate on weakness and let it appreciate gradually as the story unfolds. It will take longer than a week, but should be a good one - I have held many CSM plays: ESG, AOE, QGC and they all take a bit of patience but very rewarding in long run.
Oppies are no worries - very long dated.
