Rimfire Pacific Mining (RIM) Investor Update summary

Market overview and strategic context

• Scandium is a critical mineral with unique properties, driving demand in aerospace, defense, and decarbonization sectors.

• Global supply is highly constrained, with China as the dominant producer, creating geopolitical risk.

• Australia, particularly the Fifield region, is emerging as a key secure supply hub, attracting international attention and investment.

• The U.S. Export-Import Bank and U.S. Defense Logistics Agency have shown recent interest in the region's projects.

Project portfolio and regional collaboration

• The company holds three contiguous projects in Fifield: Fifield, Avondale (JV with GPR), and 100%-owned Rabbit Trap.

• The region hosts three major players (including Rio Tinto and Sunrise Energy Metals), with potential for shared infrastructure and a hub-and-spoke processing model.

• The geology features scandium-rich ultramafic rocks, with near-surface laterite profiles ideal for extraction.

• Rabbit Trap offers both a known scandium occurrence and several untested magnetic anomalies with significant potential.

• The company is fully funded for upcoming Rabbit Trap drilling, with activity set to begin after the harvest in December.

Operational and exploration updates
