source is stated at the bottom of the snip.I haven't been able to find a current chart showing AISC comparisons. What I have found reading through announcements is the cheapest copper mines in 2020 who had AISC of 70c are now closer to $1.60+ (only a handful I could find sub $2) the majority are above $2.
CYM aisc would place it imo probably around middle. Compare that to 29N or others who's aisc are now $3.50+ and you'll find plenty of production is underwater at current copper prices let alone sub $3.
