Wide Zones of 1.33 g/t PGE Confirmed at Mission Sill; Diamond Drilling to Start Soon

Galileo Mining’s recent drilling at its Norseman project has confirmed promising palladium-platinum-gold mineralisation near surface, with a funded diamond drilling program poised to test for deeper extensions beneath the Callisto deposit.

  • RC drilling reveals wide zones of shallow PGE mineralisation at Mission Sill
  • Diamond core drilling beneath 17.5Mt Callisto resource to commence in late February
  • Improved metal prices prompt new metallurgical test work on Callisto samples
  • Over $9 million in funding supports ongoing exploration and development
  • Mission Sill prospect shows structural targets indicating potential for larger mineralised system

Drill Results Confirm Shallow PGE Mineralisation

Galileo Mining Ltd (ASX – GAL) has announced encouraging results from its recent reverse circulation (RC) drilling campaign at the Norseman project in Western Australia. The drilling focused on the Mission Sill prospect, where multiple wide zones of palladium, platinum, and gold (collectively known as PGE) mineralisation were intersected near surface. Highlights include intervals such as 8 metres at 1.33 grams per tonne (g/t) 3E from 24 metres depth, and 8 metres at 1.20 g/t 3E from 8 metres, confirming the prospectivity of this area.

These results build on previous aircore drilling and geochemical surveys, reinforcing the view that Mission Sill hosts a shallow expression of a potentially larger and deeper mineralised system. The prospect extends over a 10-kilometre strike length, with recent drilling identifying a structural target at its southern end where magnetic imagery shows a distinctive reorientation, possibly localising mineralisation in the bedrock.

Upcoming Diamond Drilling Targets Deeper Mineralisation

Looking ahead, Galileo is preparing to commence a diamond core drilling program beneath the existing Callisto deposit, a 17.5 million tonne resource discovered in 2022 and reported in 2023. This program, supported by up to $180,000 in funding from the Western Australian Exploration Incentive Scheme, aims to test for repeats of the mineralised intrusive sill at depth and to better understand the deposit’s formation.

The initial diamond hole is planned to reach 600 metres, with potential extensions depending on results. This deeper drilling will also provide fresh samples for metallurgical test work, which is timely given the recent rise in metal prices for palladium, platinum, gold, rhodium, and copper since the last resource estimate.

Metal Price Improvements and Metallurgical Testing

Since the 2023 Mineral Resource Estimate for Callisto, spot prices for key metals have improved significantly, with palladium up from US$1,600 to US$1,639 per ounce, platinum from US$975 to US$2,067, and gold from US$1,870 to US$4,725, among others. This positive price environment enhances the economic potential of the project and has prompted Galileo to plan new metallurgical test work to optimise metal recovery processes.

Early-stage flotation tests on sulphide samples have shown excellent recoveries, and the upcoming diamond drilling will supply additional material to refine these processes. The company believes that the mineralisation is amenable to conventional crushing, milling, and flotation techniques, supporting reasonable prospects for eventual economic extraction.

Strong Funding Position and Strategic Outlook

With over $9 million in available funding, Galileo is well positioned to advance exploration and development activities at Norseman. The company’s Managing Director, Brad Underwood, emphasised the significance of the Mission Sill results and the potential for expanding the Callisto resource. He highlighted the extensive prospective strike and the structural targets identified, which may indicate further mineralisation in the bedrock.

In addition to Mission Sill and Callisto, drilling at other prospects such as Jimberlana South and Callisto North has intersected sulphides, underscoring the overall prospectivity of the Norseman project area. Further sampling and analysis are planned to better understand the geological controls on mineralisation.

Galileo’s Norseman project remains a compelling exploration story in one of Western Australia’s most prospective PGE and base metal regions, with ongoing work expected to provide further clarity on resource growth potential.

Bottom Line?

As Galileo Mining advances its drilling and metallurgical programs, investors will be watching closely for signs of resource expansion and improved project economics amid rising metal prices.

Questions in the middle?

  • Will the upcoming diamond drilling confirm deeper extensions of the Callisto mineralisation?
  • How will new metallurgical test results impact the projected recoveries and economic viability?
  • What is the potential scale and grade variability along the 10km Mission Sill prospect?
