Galileo Mining Launches 5,000m Drilling to Expand Norseman PGM Potential
Galileo Mining has kicked off a targeted 5,000-metre aircore drilling campaign at its Norseman project, aiming to build on its unique Platreef-style PGM-nickel-copper resource with new sulphide discoveries.
- 5,000m aircore drilling underway at Norseman
- Focus on Mission Sill and Callisto South prospects
- Callisto hosts 17.5Mt at 1.04g/t 4E PGM-nickel-copper resource
- Geophysical anomalies guide drilling targets
- Metallurgical work supports conventional processing
Drilling Campaign Targets Sulphide Zones at Norseman
Galileo Mining Ltd (ASX:GAL) has commenced a 5,000-metre aircore drilling program at its 100% owned Norseman project in Western Australia, focusing on Platinum Group Metals (PGMs) and associated base metals. The campaign is designed to infill and extend known sulphide mineralisation at the Mission Sill prospect, where previous shallow intercepts returned anomalous PGM grades. This drilling is underpinned by compelling geophysical data, including a strong induced polarisation (IP) anomaly adjacent to a gravity trend considered prospective for mineralisation.
Mission Sill’s sulphide zones have been a focus following recent diamond drilling that identified extensive PGM mineralisation, reinforcing the potential for multiple stacked sills across the project area. The current aircore program aims to test these zones more systematically, with drilling expected to take approximately three weeks.
Expanding Callisto’s Footprint with Follow-Up Drilling
Beyond Mission Sill, Galileo plans first-pass aircore drilling at the southern end of the Callisto South prospect. This follows anomalous PGM results from diamond drilling beneath the Callisto deposit, which was discovered in 2022 and represents Australia’s first Platreef-style PGM-nickel-copper resource. The Callisto deposit currently holds a maiden JORC resource of 17.5 million tonnes grading 1.04g/t 4E (palladium, platinum, gold, rhodium) with notable nickel and copper credits.
Additional drilling along strike at Callisto North and South is intended to test for further mineralised sills, potentially expanding the resource base. Metallurgical test work to date suggests the mineralisation is amenable to conventional crushing, milling, and flotation, with reasonable prospects for economic extraction.
Strategic Positioning in Western Australia’s PGM and Base Metals Sector
The Norseman project covers 255 square kilometres and includes several regional prospects such as Jimberlana and Mission Sill, all prospective for PGMs, nickel, copper, cobalt, and rhodium. Galileo’s tenure is strategically located near established mining infrastructure, enhancing its development potential.
In parallel, Galileo maintains a 67% interest in a joint venture with the Creasy Group over Fraser Range tenements targeting nickel-copper sulphide deposits analogous to the nearby Nova mine. This diversified portfolio positions Galileo to capitalise on demand for battery and precious metals.
Bottom Line?
The current drilling campaign is a critical step in testing Norseman’s sulphide potential beyond Callisto, with assay results poised to shape the project's next phase.
Questions in the middle?
- Will assay results confirm extensions of PGM mineralisation at Mission Sill and Callisto South?
- How might metallurgical test outcomes influence project economics and processing design?
- Could new discoveries at Norseman alter Galileo’s strategic focus or JV priorities?
