AUZ - Why has it dropped from 16 cents to 8 cents approx???

AUZ come out with a big announcement saying they've secured $20m in funding which saw the shares rocket from 9.5 cents to like 13 cents in the same day, then went up again to around 16 cents I think, before plummeting over the past 10-14 days approx. to about 8.5cents today. I thought given such a positive announcement would have at least kept the shares fairly steady or increased, but it's just been doom and gloom with always every day since the share price has fallen - WHY?

Have I missed a "bad news" announcement by this company which has seen the share price plummet?

It's almost like the share price has gone back to the 8.5cents these 2 investors who put in $20m paid.
