Cadia is made up of a series of multiple deposits. Underground resources projected to surface.

Deposit outlines:

• Aqua = porphyry
• Purple = skarn

Cadia

The worlds largest alkalic porphyry system

• Cadia on-going mine expansion and comprised of 5 main intrusive deposits
  • Mar’21 quarter production from Cadia East Panel Caves1:
    • 179,546oz gold
    • $1911/oz AISC margin (AISC negative $160/oz)
    • 0.94g/t Au and 0.41% Cu head grade
• Core of the systems not evident in the top 50 metres
• Outcropping and near surface skarns systems historically mined and assisted understand the geneses of the Cadia district
