Galileo Mining Ltd (ASX:GAL, OTC:GLMGF) has started a 3,000-metre reverse circulation (RC) drilling program north of the Callisto deposit at its 100%-owned Norseman Project in Western Australia.
This quick-fire program is expected to last approximately five weeks and is targeting nickel and palladium with first assays due to be delivered in June.
Drill targets are between one and five kilometres from the 17.5 million tonnes Callisto resource and drilling is designed to test strongly chargeable geophysical anomalies along strike.
Aiming for further discoveries
“Campaign drilling at our Norseman project is underway as we aim to make further discoveries in this new mineral province," Galileo managing director Brad Underwood said.
“The Callisto deposit is the first of its kind in the area and we believe the potential for additional mineralisation is highly significant.
"The current targets are between one and five kilometres along strike from Callisto and each has a favourable geophysical signature prospective for sulphides.
“Our exploration strategy follows a cyclical pattern with campaign drilling, review and interpretation of results, integration of new information and then follow-up drilling. We believe this cycle of exploration activity gives us the best opportunity of making further discoveries.
“We look forward to the results of the current round of drilling as we seek to unlock the potential of a newly discovered mineral province.”
Drill targets follow IP results
Geophysical work at the Callisto North prospect led to the identification of promising drill targets, informed by follow-up Induced Polarization (IP) results.
The results confirmed significant chargeable responses at lines 6,452,000 and 6,453,200. Additional surveying on infill line 6,449,100, located just one kilometre north of the Callisto deposit, revealed a considerable IP anomaly.
Data analysis suggests that the rock formations at this site have undergone structural changes and exhibit a westward dip, contrasting with the flat orientation of the Callisto deposit before it dips eastward. The IP inversion models for each priority line are depicted below.

About Norseman
Galileo owns 100% of the Norseman Project, which encompasses Callisto along with the regional prospects of Jimberlana and Mission Sill.
These areas hold potential for palladium, platinum, nickel, copper, cobalt and rhodium mineralisation. Spanning a total area of 255 square kilometres, Galileo's tenure at Norseman includes mining, exploration and prospecting licenses.
Discovered in 2022, the Callisto deposit is the first of its type in Australia, mirroring the Platreef deposits of South Africa in terms of mineralisation style.
An initial mineral resource estimate was reported in 2023 with 17.5 million tonnes at 1.04 g/t 4E, 0.20% nickel, 0.16% copper (2.3 g/t PdEq or 0.52% NiEq).
