WIDE SULPHIDE ZONES CONTINUE NORTH OF CALLISTO

Highlights

• Latest drill results show disseminated sulphide mineralisation continuing north of the Callisto discovery along the prospective five kilometre target horizon

• Drill intersection NRDD423 returned a major intersection over 100 metres north of previous drilling with;

o 54 metres @ 0.76 g/t 3E1 (0.60 g/t Pd, 0.12 g/t Pt, 0.03 g/t Au), 0.12% Cu & 0.18% Ni from 493m (NRDD423) including higher grade interval of

o 10 metres @ 1.27 g/t 3E (1.02 g/t Pd, 0.19 g/t Pt, 0.05 g/t Au), 0.19% Cu & 0.25% Ni from 515m

• Geological modelling demonstrates the consistent nature of mineralisation starting from approximately 100 metres below surface

• Resource modelling is planned to understand the potential for economic extraction. Resource modelling will also assist in targeting new economic discoveries along strike and within the broader Norseman project area

• Jimberlana and Mission Sill exploration drilling on track for commencement in late June with an initial 4,000 metre program

• Mission Sill and Jimberlana are advanced prospects with anomalous Galileo aircore drill results and compelling geophysical EM targets2

Galileo Mining Ltd (ASX: GAL, “Galileo” or the “Company”) is pleased to announce drill results from the Callisto palladium-nickel discovery together with an update on drilling preparations for new targets within the Company’s 100% owned Norseman project in Western Australia.

Galileo’s Managing Director Brad Underwood commented; “The significance of the Callisto discovery at our Norseman Project has yet to be fully realised as we continue to intercept wide zones of sulphide well to the north of the original discovery. This bodes well for the potential discoveryof new sulphide zones along the five kilometres of untested strike length tothe north.

Diamond drilling will continue at Callisto as weundertake RC drilling at the Mission Sill and Jimberlana prospects located justsix kilometres southeast of Callisto within very similar mafic-ultramaficgeology. The Jimberlana and Mission Sill targets both contain numerous earlystage aircore results with anomalous nickel, palladium, platinum, and copper.

We aim to repeat the Callisto success with newdiscoveries from our extensive 255km2 Norseman Project and, with multiplehigh-quality targets for testing, we are excited to be working within a newlydiscovered nickel-palladium district.”

Step out drilling to the north of Callistocontinues to define a mineralised pyroxenite intrusion at the base of amafic-ultramafic unit within the much larger intrusive sill complex. Figure 1shows the location of the most recent results from NRDD423 and previous resultsto the south from NRCD394. The mineralised sill at this location matches thegeometry of the interpreted target horizon that extends to the north.
