Summary
Galileo Mining Ltd (ASX: GAL) reported strong metallurgical test work from diamond core at its 100%-owned Norseman Project in Western Australia, with Callisto resource sample 26NRDD525 delivering conventional flotation recoveries of up to 85.1% palladium and 94.2% copper, supporting the view that Callisto-style disseminated sulphide mineralisation is amenable to standard processing and that similar sulphide discoveries across the district may behave likewise; the tested 12-metre composite from 147m to 159m had head grades of 2.05 g/t palladium, 0.43% copper, 0.39% nickel, 0.32 g/t platinum and 0.10 g/t gold, while exploration activity has advanced with 3,568m of aircore drilling completed at North Callisto, reconnaissance areas further north along strike, and the South Callisto gold prospect, with assays expected in about six weeks, and an approximately 2,000m RC program scheduled to begin in early November at the Mission Sill prospect targeting shallow sulphide-rich PGM-copper zones down dip and along strike across two anomalous trends defined over 1.4km (Zone A) and 2km (Zone B), including previously reported intercepts such as 8m at 0.42 g/t 3E from 24m including 2m at 0.88 g/t 3E, 17m at 0.36 g/t 3E from 84m including 5m at 0.61 g/t 3E, and 16m at 0.27 g/t 3E from 88m.
Key Points
  • Galileo Mining Ltd announced strong metallurgical recoveries at Callisto ahead of Mission Sill drilling.
  • Metallurgical testing on Callisto diamond core achieved up to 85.1% palladium recovery and 94.2% copper recovery using conventional flotation.
  • The tested composite sample from hole 26NRDD525 covered 147m to 159m within the disseminated sulphide mineralised zone.
  • Head grades of the metallurgical sample were 2.05 g/t palladium, 0.43% copper, 0.39% nickel, 0.32 g/t platinum and 0.10 g/t gold.
  • Results indicate Norseman disseminated sulphide mineralisation is amenable to standard flotation techniques at relatively coarse grind sizes.
  • Galileo said the metallurgical outcome increases confidence that future sulphide discoveries in the Norseman district could show similar processing performance.
  • Aircore drilling has been completed at North Callisto, additional reconnaissance areas along strike, and the South Callisto gold prospect.
  • A total of 3,568m was drilled in the recent aircore program and assays are expected in approximately six weeks.
  • An RC drilling program of around 2,000m is scheduled to commence in early November at the Mission Sill prospect.
  • Mission Sill exploration is focused on two broad PGM anomalous zones extending 1.4km in Zone A and 2km in Zone B.
  • Previous Mission Sill results highlighted include 8m at 0.42 g/t 3E from 24m including 2m at 0.88 g/t 3E.
  • Previous Mission Sill results highlighted include 17m at 0.36 g/t 3E from 84m including 5m at 0.61 g/t 3E.
  • Previous Mission Sill results highlighted include 16m at 0.27 g/t 3E from 88m.
  • The upcoming Mission Sill RC program will target sulphide mineralisation both down dip and along strike.
  • Galileo’s Callisto deposit was referenced as a 17.5Mt resource and remains the benchmark for nearby exploration targets.
