I think this rally is more TA driven than blog driven. There were lots of profit takers from when the stock was in the doldrums last year who held the stock back the last couple of months even though zinc rallied over 50%. Those sellers were finally taken out, unleashing the buy-side demand on this breakout.
IMO, the fundamentals point much higher, especially if they can show silver/copper in addition to zinc. The profit takers could only hold it down so long...
