Galileo Mining Ltd (ASX: GAL) has kicked-off RC drilling north of the Callisto deposit has commenced at the company’s 100% owned Norseman project in Western Australia.
“RC drilling has commenced at our Norseman Project with a number of high priority targets to be drilled in this work programme,” Managing Director, Brad Underwood, said.
“Having proven the prospectivity of the area with the discovery of the Callisto deposit, we are now exploring this newly discovered fertile region for further resources. The current program will be drilling a combination of geophysical and geochemical targets between one and five kilometres north of Callisto.
“At the same time, we are continuing our target generation through detailed interpretation of the large-scale IP geophysical data sets we have collected over the entire prospective belt.
“With $13.6 million in cash we are fully funded to undertake all planned activities, and we will maintain our focus on exploration through the present market conditions. We believe a new resource discovery will always create value, and that is what we aim for each time we go drilling.”
Drill targets are based on the results of down hole EM surveying, updated IP survey data, and geochemical/geological targeting. All targets are within the Callisto North prospect between one and five kilometres north of the Callisto deposit.
Downhole EM surveying was undertaken on drill hole, which was originally drilled into a high chargeability/low resistivity geophysical anomaly defined by pole-dipole IP surveying. The geology intersected in drill hole NRC493 was unable to explain the geophysical response while intersecting a thick zone of ultramafic rock interpreted to be a unit of the same prospective sill which hosts the Callisto nickel-copper-PGE deposit.
Data from the down hole EM survey showed a highly conductive response which was modelled with a plate size of 202 metres strike length, 432m down dip extent, and a conductance of 16,129S. The model dips to the southeast and passes approximately 100m beneath the drill hole NRC493.
Another prospective result from the May 2024 round of drilling was received from NRC498, drilled adjacent to a moderately strong geophysical response. This chargeable response will be the subject of follow up drill testing in the current drill programme.
Further prospective results were received from NRC496 drilled on section line 6,449,700. A large zone of anomalous mineralisation has been identified in ultramafic rock which broadly matches the top of a change in chargeable response and a change in geology to the west. This target will be drilled to determine whether the subtle geophysical response and the ultramafic/mafic contact zone are linked to zones of mineralisation.
Regional pole-dipole surveying of the 20km Callisto trend and the 12km Mission Sill trend is now complete with ongoing interpretation to determine which geophysical responses will be selected for drill testing.
The exploration strategy is to build on the understanding of the geophysical data gained from recent drilling and to continue working from areas of higher data density (areas with drilling) to those with no drilling.
