Galileo Mining Ltd (ASX:GAL, OTC:GLMGF) has intersected wide sulphide zones continuing north of the Callisto palladium-nickel discovery along a prospective five-kilometre target horizon within the Norseman Project in Western Australia.
The highlight is drill hole NRDD423, which returned a major intersection over 100 metres north of the previous drilling, including 54 metres at 0.60 g/t palladium 0.12 g/t platinum, 0.03 g/t gold, 0.12% copper and 0.18% nickel from 493 metres. This included a higher grade interval of 10 metres at 1.27 g/t 1.02 g/t palladium, 0.19 g/t platinum, 0.05 g/t gold, 0.19% copper and 0.25% nickel from 515 metres.
Furthermore, a 4,000-metre reverse circulation drill campaign is on track to kick off at the Jimberlana and Mission Sill prospects in late June with drilling expected to take around one month to complete.
Encouragingly, these prospects have shown promising results from previous Galileo aircore drilling and are compelling geophysical electromagnetic targets.
Potential discovery of new zones
Galileo managing director Brad Underwood said: “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 discovery of new sulphide zones along the five kilometres of untested strike length to the north.”
Geological and resource modelling
Geological modelling has emphasised the consistent nature of mineralisation, starting from about 100 metres below the surface.
The modelling will support resource modelling efforts, which will evaluate the economic viability of this style of mineralisation and guide further exploration targeting.
Meanwhile, the upcoming resource modelling phase will assess the economic viability of extraction and aid in the identification of potential discoveries within the broader Norseman project area.
Forward plan
Galileo Mining's undercover discovery at Callisto presents encouraging prospects for additional mineralised intrusions within the five-kilometre prospective horizon to the north.
The company remains optimistic about the future of its ongoing exploration and the potential for significant economic opportunities in the region.
Underwood adds: “Diamond drilling will continue at Callisto as we undertake RC drilling at the Mission Sill and Jimberlana prospects located just six kilometres southeast of Callisto within very similar mafic-ultramafic geology.
“The Jimberlana and Mission Sill targets both contain numerous early-stage aircore results with anomalous nickel, palladium, platinum and copper.
“We aim to repeat the Callisto success with new discoveries from our extensive 255 square kilometres Norseman Project and, with multiple high-quality targets for testing, we are excited to be working within a newly discovered nickel-palladium district."
Step-out drilling to the north of Callisto continues to define a mineralised pyroxenite intrusion at the base of a mafic-ultramafic unit within the much larger intrusive sill complex.
The mineralised sill at this location matches the geometry of the interpreted target horizon that extends to the north.
