HPA demand compounding ~23% p.a. into a structural 4N supply deficit.A large market pulling ahead of supply04 THE INVESTMENT CASE Five reasons Impact is undervalued 01 A globally significant, low-cost HPA resource A shallow salt-lake orebody in Tier-1 WA, JORC-compliant, with completed PFS economics. A differentiated, lower-carbon process A patented low-temperature leach producing 4N HPA at a fraction of incumbent emissions.02 A clear, government-backed path to production Each study and pilot milestone a discrete, fundable re- rating opportunity.05 WHY IT MATTERS Technical de-risking has outrun the share price — the value gap is the opportunity.
