A minor correction to my earlier post: the 61.8% retracement of the last leg - from 46.5c in December 2011 to 99c in March 2012 - is 66.5c (not 65.5c). Apologies to anyone who cares about this sort of thing!
By way of background, 61.8% is a fibonacci ratio. Often a share price will retrace/correct between 50% and 61.8% of an upward move before resuming the uptrend. It can be quite a good buying zone, and it certainly has been for AZH since mid-2010.
