Notes:
- Note – Rounding discrepancies may occur.
- Note – Mount Hope is 100% CNB, excluding the small 6kt South Hope MRE which is 51% owned by CNB and part of the Hammer Metals Limited JV. Trekelano, Nil Desperandum, Lady Fanny, Mount Birnie, Mohawk and Duchess are 100% CNB.
- Note – Metal equivalents for MREs at Mount Hope, Trekelano, Nil Desperandum, Lady Fanny and Mohawk have been calculated using the formula CuEq=Cu% + (Au_ppm * 0.85) and is based on review of consensus forecast prices of US$8,505/t for copper and US$2,520/oz for gold, exchange rate of 0.63 and recovery of 95% copper and 85% gold as demonstrated in preliminary metallurgical test work carried out in 2023. Metal equivalents for MREs at Duchess and Mount Birnie have been calculated using the formula CuEq=Cu% + (Au_ppm * 0.7) and is based on September 2023 spot prices of US$8,500/t for copper and US$1,950/oz for gold, exchange rate of 0.67 and recovery of 95% copper and 90% gold as demonstrated in preliminary metallurgical test work carried out in 2023. Individual mineral resource estimate grades for the metals are set out at Table 6 of this announcement. It is the Company’s opinion that all the elements included in the metal equivalents calculation have a reasonable potential to be recovered and sold.
