The $7.9 Million will be linked to non fixed variables. I.e Labour, Drill Bits, Explosives, Diesel, Trucking the ore, Additives for processing. The higher grade wont necessarily correlate to reduced costs.
So (5181 * 1700) - 7900000 = 900 000. This is not a bad effort and much better then expected however I think around the $1 million mark is more realistic.
This would put costs at 7900000/5181 = 1519. Note this isn't the aisc as it includes things like development which can be written off as capital.
Any which way you split it though, this thing is undervalued. I'd be super happy if the number realeased in 5 weeks time is closer to yours then mine but hopefully we get some updates between now and then and the grade continues on the expected trajectory.
