It appears when I was working out AISC that I was mainly relying on Management's last figures on this subject being Slide20 in the Equity Raising Presentation announced on 27Mar23 that is below - they worked this out on 110k ozs Au being the projected LOM average and came up with an AISC of US$1255/oz - I reduced this to $1200 based on 120k ozs Au produced.
Anyway due to the gold price increasing their royalty and refining percentage on revenue has now increased from 15% to 21% due to the increasing scale that they have to pay which bumps up this line on the AISC calculation by over $100. They have not updated the market on current Chatree costs as yet so they remain very airy-fairy so we should be cautious in any calculations.
I have attempted a new AISC calculation that comes out closer to US$1460/oz but it shouldn't be relied on at this stage as I'm just guessing at likely Mining and Processing costs.
