Galileo Mining (GAL) Investor presentation summary

Investment case

• Norseman Project covers 255km² in Western Australia’s Goldfields, 10km from Norseman, with access to road, rail, gas, water and Esperance port.

• Callisto is a palladium-platinum-rhodium-gold-nickel-copper sulphide discovery; first discovery hole returned 33m at 2.05g/t 4E, 0.32% Cu and 0.30% Ni from 144m.

• The presentation cites a strong exploration team, priority drill-ready targets, and substantial shareholders Mark Creasy and IGO.

Callisto resource and metallurgy

• Indicated and inferred resource totals 17.48Mt at 1.04g/t 4E, 0.20% Ni and 0.16% Cu, equivalent to 2.3g/t PdEq; contained metal includes 585koz 4E, 35kt Ni and 28kt Cu.

• Indicated resource is 7.96Mt, or 46% of the total, at 2.5g/t PdEq; unclassified mineralisation continues below the resource, which remains open at depth.

• Flotation at a 75µm grind achieved recoveries of 94% Cu, 82% Pd, 77% Ni, 79% Au, 78% Pt and 63% Rh; initial results indicate potential for a single bulk concentrate.

Exploration pipeline

• Callisto mineralisation starts 75m below surface, extends ~300m along strike and 800m down dip, and averages ~40m true thickness; the host ultramafic complex has a magnetic signature traceable for 20km.

• Exploration targets include 20km of prospective strike around Callisto and a further 12km around Mission Sill, with the model based on South Africa’s Platreef deposits.

• North Callisto surface rock chips 2km north of the resource returned up to 1.87g/t 3E; first-pass drilling was scheduled to begin in late September 2026.

• Mission Sill aircore results define Zone A over 1.4km and Zone B over 2km; RC drilling to test further mineralisation was scheduled for November 2026.

• September–December 2026 plans include North Callisto aircore drilling, RC campaigns at Mission Sill and along Callisto, prospecting and mapping, and integration of geophysical and geochemical data.
