Why palladium? Trump 2.0 policy settings, rapid growth of hybrid-ICE vehicles and price at cyclical lows - CHN leveraged to price rebound

Why palladium? Battery electric vehicle adoption has slowed

dramatically and demand for ICE/hybrid vehicles continues to grow

Total passenger vehicle sales (China, US, Europe)

Global BEV market share

Vehicles with Pd (ICE, Hybrid)

Palladium demand driven largely by automative

catalytic converter production…

Our outlook

Growing with urbanisation

BEV adoption slowed, range

anxiety, lack of

infrastructure, govt

incentives being repealed

Increased hybrid production, higher loadings and stricter emissions standards

  • but slowing BEV growth, Trump 2.0 policy settings not yet reflected in consensus palladium demand forecasts

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

Russian palladium never officially sanctioned, has been sold almost exclusively to China since the Ukraine invasion

  • Production largely from ageing, deep, under- invested mining complexes in Russia and South Africa
  • South African producers have underspent ~$18Bn in capital in the last decade, leading to supply deficits in 10 of the last 11 years,
  • Large number of South African producers operating at a loss, with further curtailments likely
  • The two mines in the western world (Stillwater and Lac des Iles) are loss making and are being curtailed, making supply concentration worse
  • Weak prices and lack of investment is driving a decline in recycling volumes (not growth as most are forecasting)

Why palladium? Supply forecasts are always overly optimistic - large

number of mines are loss making and recycling underperforms

Primary PGE Supply Actual vs Forecasts

Recycled PGE Supply Actual vs Forecasts

Supply forecasts are notoriously optimistic, and with growing demand → prolonged deficits → higher long-term prices

Gonneville PGE-Ni-Cu-Co Project Overview

A new long-life, low-cost, low-carbon, strategic critical minerals project in Western Australia

Strategic non-binding MOU with Mitsubishi Corporation

Top tier development partner,

collaborating on the PFS and offtake strategy1

Tier 1 scale sulphide Resource

Unique critical minerals exposure

17Moz of Pd-Pt-Au (3E), 960kt Ni, 540kt Cu, 96kt Co contained2

Revenue split of ~50% Pd, ~20% Ni, ~20% Cu, ~10% Au/Pt/Co3

Competitive cost profile

Low-risk development location

Predicted to become lowest cost

Mine infrastructure on ~22km2 of

PGE producer in western world

Drilled out to Indicated category, to depth of ~450m, Inferred Resources continue to depth of 1,100m

Acquired 22km2 of farmland surrounding the Resource in 2021-22, significantly de-risking the Project

Dan Brearley commenced as COO in March 2025, key roles secured (Geology, Metallurgy, Mining, Infrastructure, 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 solutions and 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 post PFS completion

Targeted in ~2027

  • Over 600 flotation tests completed with incremental improvements on each test
  • Final breakthrough driven by a new reagent mix, grind size and froth height in the flotation circuit optmised for a bulk feed in a low-priceenvironment
  • Potential recovery improvements still possible from remaining locked cycle testing to be completed
