750 k shares in first 15 minutes

Some excitement in this stock, finally. It has gone from ridiculously underpriced to just underpriced. Is ERM buying more, hoping for a quick profit or securing gas supply for the future? Is LNG buying more hoping for a takeover, perhaps a deal with ERM? Do both just want a blocking stake? Is it just traders (apparently the chart is looking good and these things are self-fulfilling prophecies)? Will it continue to 70c on momentum or will it stall at 60c and gradually drift back to the 40's on lack of interest? I'm not selling today - I've never sold MEL - but at least there's some fun to be had watching and speculating.
