Rimfire Pacific Mining (RIM) Investor presentation summary

Scandium market and demand drivers

• Scandium oxide prices range from US$1.2M–$3.8M/t, with metal ingot and dendritic forms commanding much higher values up to US$513M/t.

• Key applications include solid oxide fuel cells, advanced aerospace alloys, and semiconductors, with demand constrained by limited global supply and geopolitical risks.

• China dominates scandium supply, producing 100% of refined metal and 85% of oxide, creating supply risk.

• Forecasts show scandium oxide demand rising sharply through 2036.

Australian scandium resources and project positioning

• NSW holds 74% of Australia’s known scandium resources (~37Kt), with Fifield recognized as a major scandium district.

• Major deposits in the region include Syerston (SRL), Murga (RIM), and others, with Rimfire’s Murga project adjacent to the world’s largest, highest-grade Syerston deposit.

• Murga’s current MRE is 4Kt @ 190ppm Sc Oxide, with an exploration target of 15–46Kt Sc Oxide.

• Murga mineralization is hosted in laterite over pyroxenite rocks, with recent drilling confirming significant scandium intercepts.

Project development and exploration progress

• Murga is 100% owned, with GPR earning 50.1%; focus is on converting the exploration target to a mineral resource estimate (MRE) in Q1 2026.

• Recent drill results include intercepts up to 16m @ 231ppm Sc and 35m @ 157ppm Sc, supporting resource growth.

• Metallurgical test work and further drilling at Rabbit Trap are planned for 2026 to expand scandium resources.
