Not a guru here but my 2 cents regarding AISC. Many costs for a mine is fixed therefore the more you produce the less the AISC. The major improvement for BLK's AISC for the previous quarter was due to more gold being produced, so I see 2 factors for the market to restore confidence in BLK - consistent gold production meeting target with little variance and continuous debt reduction to nil.
