  • Trump 2.0 administration repealing incentives for BEVs and elsewhere they are under threat
  • Western car manufacturers are scaling back their BEV growth ambitions, and scaling up hybrid production to meet consumer preferences
  • More palladium required in hybrid EVs than internal combustion engine vehicles (ICE)
  • Slowing BEV growth and Trump 2.0 policy settings are not yet reflected in consensus palladium demand forecasts

Why palladium? Supply is concentrated in Russia and South Africa where supply risks are high, disruptions are common, plus recycling is subdued

mining complexes in Russia and South Africa

•

The two mines in the western world are loss making and

are being curtailed, making supply concentration worse

• Weak prices and lack of investment is driving a rapid

decline in recycling volumes (not growth as most are

forecasting)

•

South African producers have underspent ~$18B in capital

in the last decade, leading to supply deficits in 10 of the

last 11 years, with further supply declines likely

Dan Brearley commencing as COO in March 2025, key roles secured (Geology, Metallurgy, Mining, Marketing, Approvals, Community)

Simple flotation and CIL to produce saleable concentrates and doré - a major recent breakthrough that simplifies the Project and reduces costs

Water-power corridors defined, TSF design complete, scoping cost estimate completed and Govt supportive

Saleable products confirmed, indicative terms continuing to improve and high levels of interest from potential offtakers

Referred Project in early 2024, Strategic and Major Project Status awarded, strong level of local community support

Discussions to commence in H2 2025

Targeted in ~2027

1. Refer to ASX Announcement on 17 February 2025 for full details.

2. The preferred development case for the PFS is expected to have a production profile based on the 2023 Scoping Study but at a reduced scale.

Simplifying the flowsheet has materially reduced costs and risk, and is expected to enhance margins for a bulk open-pitoperation

Item

Impact of new process flowsheet

Capital costs

• Significant reduction due to removal of hydrometallurgical process (~A$260M)

(pre-production)

Operating costs (sulphide)

  • Significant reduction due to removal of hydrometallurgical process (~A$4.10/t processed) and reduction of leach reagent consumption (by ~70%)
  • A 10% tax offset expected on CIL operating costs
  • No material change expected for other processes

Recoveries

•

Marginally lower overall recoveries, but outweighed by expected reduction in costs - testwork and

optimisations continue, which have potential to improve recoveries further

Ni-Co Payabilities

•

Marginally lower Ni-Co payabilities through selling concentrate vs MHP, but outweighed by expected

reduction in costs

Complexity/risk

• Materially reduced, utilising all simple, proven, industry standard technology

  • Margins for a bulk open-pit mine plan are expected to improve significantly relative to the 2023 Scoping

Margins

Study (using conservative, consistent macro-economic assumptions) as a result of the process flowsheet

optimisations

1. Refer to ASX Announcement on 17 February for full details. The preferred development case for the PFS is expected to be reduced in scale relative to the 2023 Scoping Study and as such, the hydromet process cost estimates listed are indicative and for comparison purposes only.
