IMO, the only thing that will stop avz from appreciating in price is if extensive drilling results are a dud. I haven't been trading mining stocks long as my main game is trading cfds on blue chip bank stocks.

Has anyone here (who have been trading mining stocks for a long time) ever witnessed a mining stock that has had exceptional initial drill results but have failed to match those results with extensive drilling? How likely is it that avz's extensive drilling will return bad results?

I personally think there's zero chance but would like to hear the opinions of more knowledgeable traders.
