All future drilling will be routinely analysed for gallium

11 Future Mining and Processing considerations Mining • Underground (cut and fill) – minimize surface footprint • Over-break mining dilution of 25% modelled • Lode widths allow for use of mechanized equipment Processing • On-site - crush/grind/flotation • Treatment flowsheet (2x concentrates): 1. Zn/Ge 2. Pb/Ag (+/- Cu/Au) • Recovery of 89% Zn and 74% Pb (with single pass and open circuit) • Transport concentrates to European smelters • Germanium separation within Europe (Belgium) Concentrate grades: 57 % Zn 856 g/t Ag 63.6 % Pb 117 g/t Ge 2.62 % Cu 0.52 g/t Au

14 Rockfire The global GERMANIUM shortage Chinese germanium exports have fallen by more than 90% Germanium has risen from US$1,000/kg to over US$5,500/kg (currently US$5.8m per tonne) “As countries race for technological and military dominance, control over germanium supply chains may prove pivotal.” Fawkes Capital Management 2 October 2025 China controls 83% of the global supply of germanium https://www.globsec.org/what-we-do/press- releases/globsec-china-export-ban

15 Silicon-germanium electronic chips produce… • smaller electronic chips • less electronic noise interference from the chip itself • chips that are more energy efficient • germanium extends the life of batteries • stable signal over a wider range of temperatures • chips superior at ultrahigh frequencies.

16 Rockfire The Artificial Intelligence (AI) race for global dominance Germanium’s high electron mobility makes it essential for high- performance transistors in AI hardware. Germanium’s use in fiber-optic cables is critical for the high-speed data transmission that AI systems rely on.

18 • Forward-looking infrared (FLIR) devices form images by sensing the thermal contrast between objects and background. • Integrated into all modern vehicles for essential safety features, including: o parking assistance o blind spot detection (BSD) o lane change assist (LCA) o reverse parking sensors o “Nightdriver”, night-vision system manufactured by Raytheon allows drivers to see up to 5 times farther. Rockfire Advanced Driver Assistance Systems (ADAS)
