* Water consumption in FY2022 is negative due to the normal calculation method. This is because the amount of wastewater discharged from the mine wastewater treatment exceeded the actual water consumption. This situation is part of our sustainable resource management and is a unique case that cannot be expressed using the normal calculation method.
