Northparkes is the 2nd largest porphyry copper mine in Australia (to Cadia)

Endowment 5.5Moz Au and 4.5Mt Cu2

First quartile cash costs

Northparkes mine driven by series of porphyry pipes

  • Series of narrow but vertically extensive gold rich copper porphyry pipes
  • Deposits tend to occur as structurally controlled clusters
  • Core of the systems not evident in the top 50 metres
  • Bornite hosts the majority of copper mineralization, with majority of gold occurring as inclusions in bornite. Chalcopyrite is the dominant copper mineral in the outer regions of the bornite-rich cores
  • E22 discovery (1st DDH): 229m @ 0.61% Cu, 0.67g/t Au 1
  • E26 discovery: 441m @ 0.67% Cu1

Northparkes an expanding and very profitable mine

  • Northparkes undergoing mine expansion with life to 2047 from 5 orebodies + PEA/resource upside1
  • Commenced production in 1994: Reserve 68Mt
  • 25 years on: Reserves 133Mt and 483Mt Resources
  • Continued resource expansion and new discoveries
  • First quartile cash costs supported by efficient block caving mining method (from E48 & E26 orebodies)
  • 2019 new block cave (E26L1N) approved and mill expansion
  • E44 satellite skarn deposit at studies and permitting phases for a potential open pit mine and c.20km truck haulage to the existing mill
  • History of key project milestone
    • Discovered 1976 by Geopeko
    • Rio Tinto acquired an 80% interest in 2000 via acquisition of North
    • CMOC acquired 80% from Rio Tinto in 2013 for US$820m
    • In 2020, Triple Flag paid US$550m for a gold and silver stream
