o"Hualilans 2023 MRE included 74.3 Mt of material above an AuEq cut-off of 0.2 g/t Au, containing 2.9 Moz AuEq2 . Adding a heap leach pad for the full-scale PFS, in addition to maintaining the flotation circuit for high grade material, creates the potential to mine and process significantly more material than the 7.2Mt in the Scoping Study mine plan."
That is an order of magnitude difference between 7.2Mt in the scoping study and the 74.4Mt in the MRE .
Be nice to see a chart of tonnages in the MRE at different cut off grades to get a better stab in the dark at the potential increased NPV from adding a heap leaching circuit that runs in parallel with the CIL circuit .
Wonder if heap leaching may have been a better option than toll treating the oxide ore ?
