Most of the forecasts for first year were when DFS was done and were long before the hyperinflation impacts that came after covid. Even 2021 we didn't see the massive jumps over the subsequent 18 months.

cost of everything is up hence AISC is up by $200.

DFS forecast gold price was $1407 an ounce, seeing $1800+.

so $200 up in costs but $400 up in revenue.

AISC is really not a problem... And it will come down as they get to nameplate production (output volume will increase so cost will average down).
