We're in the wild west. I don't think there is anything we can do until ENZR becomes a real contender. The SOB is going to bitch slap this thing around for as long as he can get away with it. I have noticed some 'anomalies' here, too. But I can't track it as you appear to be able to do.
Most of the selling was on the EGZ.V market. Over 600k shares already, and some sell blocks of 143k and 198k. I think the weak markets and weak Chinese markets are creating some fear and a few sells, but this is by no means unprecedented or alarming as we await further big news.
