How to Calculate All In Sustaining Costs (AISC) I recall a while back someone was asking if the cost to acquire a property is included in or impacts All In Sustaining Costs (AISC).
The short answer is NO.
"Per the WGC Guidance Note, costs related to business combinations, acquisitions and disposals are excluded from AISC and AIC."
You can read all about AISC on the World Gold Council website:
