Galileo Mining Unveils Promising Platinum Group Element Zones at Mission Sill

Exploration Momentum at Mission Sill

Galileo Mining Ltd (ASX: GAL) has reported encouraging results from its December 2024 quarter activities, highlighting the discovery of widespread platinum group element (PGE) mineralisation at the Mission Sill prospect within its Norseman project. The company completed an extensive aircore drilling campaign, comprising 157 holes over 5,300 metres, targeting a 3-kilometre strike of prospective ultramafic host rocks.

Significant assay intervals include 32 metres at 0.44 g/t 3E (Pd + Pt + Au) from 16 metres depth and 40 metres at 0.33 g/t 3E from surface, underscoring the potential for economic mineralisation. These results are particularly notable given the Mission Sill's proximity, approximately 8 kilometres, to the 17.5 million tonne Callisto deposit, a well-defined palladium-nickel resource.

Geological Context and Strategic Significance

The Mission Sill shares a similar stratigraphic position to the Callisto deposit, with geological mapping confirming the presence of fertile basal contact zones and ultramafic-gabbroic intrusive contacts. This geological analogy strengthens the prospectivity of Mission Sill as a potential source of Callisto-style sulphide mineralisation, a style previously untested systematically across Galileo's expansive 255 km² Norseman tenure.

Managing Director Brad Underwood expressed optimism about the campaign's outcomes, emphasizing the momentum heading into the 2025 field season. He highlighted that only a fraction of the Mission Sill trend has been tested to date, with further detailed 1-metre split assays pending and follow-up drilling planned to both infill and extend the known anomalous zones.

Financial Strength and Joint Venture Developments

Financially, Galileo remains well-positioned with $11.3 million in cash as of December 31, 2024, providing ample runway for its aggressive exploration agenda. The company also advanced its lithium interests through a joint venture with Mineral Resources (ASX: MIN), which acquired a 30% stake in lithium rights over the Norseman JV tenements for A$7.5 million. Mineral Resources has commenced detailed mapping and sampling of pegmatite outcrops, aiming to delineate lithium mineralisation potential.

Meanwhile, at the Fraser Range project, a 67% Galileo-owned joint venture with the Creasy Group, a comprehensive review of electromagnetic (EM) data identified four new drill targets. These undercover prospects, located along strike from major nickel-copper deposits such as Nova and Silver Knight, are slated for drill testing in the second quarter of 2025.

Outlook and Exploration Strategy

Galileo's exploration strategy remains focused on systematic drilling to unlock the full potential of its Norseman and Fraser Range projects. The company’s approach of integrating geological mapping, geochemical assays, and geophysical surveys is designed to refine target zones and enhance discovery potential. The upcoming drilling campaigns will be critical in validating the extent and grade of mineralisation, potentially adding significant value to Galileo’s resource base.

With a robust balance sheet, a pipeline of promising targets, and a track record of methodical exploration success, Galileo Mining is poised to maintain its upward trajectory in the competitive PGE and battery metals sectors.
