Galileo Mining Ltd’s (ASX: GAL) latest drill results show disseminated sulphide mineralisation continuing north of the Callisto discovery along the prospective five kilometre target horizon within the company’s 100% owned Norseman project in Western Australia.
The company has also confirmed it is moving ahead with drilling preparations for new targets within the Norseman project.
The significance of the Callisto discovery at our Norseman Project has yet to be fully realised as we continue to intercept wide zones of sulphide well to the north of the original discovery,” Managing Director, Brad Underwood, said.
“This bodes well for the potential discovery of new sulphide zones along the five kilometres of untested strike length to the north.
“Diamond drilling will continue at Callisto as we undertake RC drilling at the Mission Sill and Jimberlana prospects located just six kilometres southeast of Callisto within very similar mafic-ultramafic geology.
“The Jimberlana and Mission Sill targets both contain numerous early stage aircore results with anomalous nickel, palladium, platinum, and copper.
We aim to repeat the Callisto success with new discoveries from our extensive 255 sq. km Norseman Project and, with multiple high-quality targets for testing, we are excited to be working within a newly discovered nickel- palladium district.”
Step out drilling to the north of Callisto continues to define a mineralised pyroxenite intrusion at the base of a mafic-ultramafic unit within the much larger intrusive sill complex. The mineralised sill at this location matches the geometry of the interpreted target horizon that extends to the north.
Geological modelling of the mineralisation intercepted to date has been completed and will be used to support resource modelling. Resource modelling is designed to investigate the potential of economic extraction for this style of mineralisation and will provide parameters for additional exploration targeting to the north of Callisto.
Typical exploration parameters include depth of mineralisation and potentially economic grades for different types of mining methods. Initial resource modelling is expected to be completed in August/September 2023 subject to the receipt of ongoing drill results.
Logging and interpretation of drill core indicates Callisto is a separate mineralised sill, with disseminated sulphide mineralised zones, that has intruded a pre-existing mafic-ultramafic sill complex.
The host sill complex has a strong magnetic signature which trends north-northeast and outcrops over a five-kilometre strike to the north. Callisto is a blind undercover discovery with strong potential for additional mineralised intrusions occurring within the five-kilometre prospective horizon to the north.
Jimberlana and Mission Sill Prospects
A 4,000 metre RC drill campaign is on track to commence at the Jimberlana and Mission Sill prospects in late June with drilling expected to take around one month to complete. The Mission Sill is a mafic-ultramafic intrusion with similar geology to the host rock at the Callisto discovery.
The Mission Sill is located approximately six km to the southeast of Callisto and has multiple anomalous drilling results over a 10 kilometre strike length. The initial target for testing is “MS3”.
