Note:

The mineral resources also contain meaningful amounts of gold and silver. Based on limited composite sample analysis, the average grade is 0.19 g/t for gold and 13.1 g/t for silver in the Cu-Fe resource, 0.17 g/t for gold and 5.7 g/t for silver in the Fe-Cu resource, and 0.61 g/t for gold and 56.7 g/t for silver for the Cu-Pb-Zn resource.
