AISC vs AICI looked into your claim AISC are not relevant. Newmont, Barrick, Agnico, Newcrest, Goldfields, Anglogold, Iamgold and others all utilize AISC as a measure to determine profitability. For example, in 2021, the Barrick/Angogold Kibali mine in the DRC produced gold at a AISC of $ 818 per oz. You highlight one company, Kinross, that employs both AISC and AIC.
I would be curious to hear your explanantion as to why the largest gold companies in the world do not follow the Kinross model?
