→ 2 Significant Near-Mine Resource Upside
Lower Cut-off Could Add Material Production and
Mine Life to CSA
• Historical resource cut-off grade materially
above profitable mines operating in close
proximity to CSA
• Tritton Mine (Aeris) and Peak Mine
(Aurelia) have a Cu resource grade of
1.2% - 1.8% vs CSA resource grade of
5.6% and cut-off of 2.5%
• Potential to add material tonnes to the
CSA mining inventory and optimize
processing plant utilization
Processing plant has a throughput
capacity potential of 1.5Mtpa(1) vs
current operating rate of 1.3Mtpa(2)
