TAKE NOTE
During 3Q21, the average C1 of Perkoa and RP was 0.78; and AISC of 0.92; production costs dropped a bit during 4Q21, especially energy.
The increase in energy during year 21 has been something of 50%, while Zn rose close to 100%. Zn is one of the raw materials that rises the most.
The rise in gas has caused the partial closure of several Zn smelters and refineries in Europe, which contributes to the increase in the price of Zn.
