Galileo Mining Ltd has scheduled two separate drilling campaigns at its 100% owned Norseman project in Western Australia to test high-priority platinum group metal targets.

A 5,000-metre aircore drilling campaign is set to begin in late September to test an outcropping mineralisation target located two kilometres north of the 17.5-million-tonne Callisto resource. Rock chip sampling across the area has returned grades of up to 1.87 g/t 3E, representing the first known occurrence of mineralised outcrop within the project area, where the main Callisto deposit sits 100 metres beneath cover.

The company holds a 100% interest in the Norseman project, which encompasses a project area with 20 kilometres of prospective strike surrounding the Callisto deposit.

In addition to the aircore program, Galileo Mining has signed a reverse circulation drilling contract scheduled to start in November. This follow-up work will test two extensive zones of platinum group metal anomalism at the Mission Sill prospect, designated Zone A across a 1.4-kilometre strike and Zone B across a 2-kilometre strike. Previous exploration at Mission Sill relied on aircore drilling and limited December 2025 reverse circulation drilling, whereas the upcoming campaign will target these mineralised zones both down-dip and along strike.

“In line with our exploration strategy of multiple targeted drill campaigns, we are preparing to undertake new drilling with two more programs. Aircore drilling of this area is scheduled to commence in the last week of September as part of a 5,000m campaign. Additional drilling is planned further north along strike following the Callisto prospective geological contact zone.”

“Prospecting work has identified mineralised outcrop just two kilometres from our 17.5Mt Callisto resource. And diamond drilling beneath the resource has shown that Callisto is not a unique mineralised occurrence in the area. These results improve the probability of further discoveries at our Norseman project and we intend to thoroughly pursue the opportunities for a breakthrough result with our upcoming drill programs.”
