  • Updated PEA values Penco at $344M after-tax NPV with a 26.1% IRR, up from $178M in 2021 but using different discount rates
  • Annual production targets 732 tonnes of rare earth oxides including 44 tonnes of dysprosium and 6 tonnes of terbium for defense and EV markets
  • Capital costs rose ~$115M and processing costs more than doubled, while NPV is highly sensitive to Western rare earth price premiums
  • First-stage environmental approval covers only 5.5 years of operations; a second assessment and Louisiana separation facility remain in progress
