Norseman PGE Prospects Deepen: Can Galileo Confirm Economic Mineralisation?

Strong Assay Results Highlight Norseman’s Potential

Galileo Mining Ltd (ASX – GAL) has released promising assay results from its recent aircore drilling campaign at the Norseman project in Western Australia. The highlight is the Mission Sill prospect, where multiple significant intersections of palladium, platinum, and gold have been reported. Notably, assays include 4 metres at 4.78 grams per tonne (g/t) combined PGE plus gold (3E) and a peak gold assay of 3.46 g/t over 4 metres, underscoring the precious metal potential of the area.

The drilling campaign, completed in July and August, comprised approximately 4,300 metres across 149 holes. It has successfully delineated over 10 kilometres of continuous PGE anomalism along the Eastern Contact Zone of the Mission Sill, a geological feature interpreted as either an internal segregation within the sill complex or a discrete sill itself. This extensive strike length of anomalism is a compelling indicator of a potentially significant mineralised system.

Strategic Follow-Up Drilling Planned

Building on these encouraging results, Galileo plans to commence a reverse circulation (RC) drilling program in late October. This next phase aims to test for bedrock mineralisation beneath the Mission Sill prospect and the Callisto Deeps prospect, the latter located near the company’s 17.5 million tonne Callisto resource. The Callisto deposit, discovered in 2022, is notable for its Platreef-style mineralisation, analogous to significant South African deposits.

The upcoming drilling will include short overlapping holes to precisely locate the ultramafic/mafic contacts in basement rock, which geological interpretation suggests may host economically significant mineralisation. Additionally, Exploration Incentive Scheme funding of up to $180,000 supports deep drilling beneath the Callisto deposit, targeting potential repeat mineralised ultramafic sills at depth.

Well-Funded and Positioned Amid Renewed Market Interest

Galileo’s Managing Director, Brad Underwood, expressed optimism about the project’s prospects, highlighting the consistent PGE anomalism and the combination of precious metals detected. The company is well capitalised with approximately $10 million in cash, positioning it strongly to advance exploration during a period of renewed market focus on palladium and platinum metals.

With the Norseman project’s extensive tenure covering 255 square kilometres and its proximity to established resources, Galileo is strategically placed to expand its footprint in the PGE sector. The integration of historical data, modern geophysical surveys, and systematic drilling is enhancing the understanding of this complex mineral system.

Looking Ahead

The forthcoming RC drilling results will be critical in confirming the depth extent and economic potential of the Mission Sill and Callisto Deeps prospects. Should these results validate the initial aircore findings, Galileo could be on the cusp of defining a new, significant PGE resource in Australia, a market traditionally dominated by South African and Russian supplies.
