Galileo Mining Ltd (ASX: GAL) has identified a new near surface target zone identified at the Jimberlana South prospect with further exploration results from RC drilling within the company’s 100% owned Norseman project in Western Australia.
Assay results from our September drill campaign show we are advancing strongly with our systematic exploration programmes aimed at unlocking the value in our Norseman project. Having made the greenfields Callisto discovery in 2022, we believe the potential of further exploration success in this under-explored province is high,” Managing Director, Brad Underwood, said.
“Our current strategy involves campaign exploration drilling, review and interpretation of results, integration of new information with geophysical data, refinement of drill targets, and then follow up exploration drilling. We believe this cycle of exploration activity will provide us the greatest opportunity for additional discoveries.
“Our next drill program is scheduled to begin this week where we will undertake first pass drilling at the South Callisto prospect and more drilling at the North Callisto prospect. Follow up drilling at the Jimberlana South prospect is scheduled in the following round of drilling expected to commence in late November.
“We are well funded to undertake our drill programs and look forward to the drill results from this new mineralised district.”
RC drill hole NRC476 was completed as a follow up to drill holes NRC455 and NRC456. Multiple sulphide zones were intersected in NRC476 with the most prospective being the upper disseminated sulphide zone within a gabbro unit of the layered mafic-ultramafic Jimberlana Dyke.
Assays from this interval showed strong enrichment in PGEs, copper, and nickel within a broad zone on the margin of the dyke. This location matches the mineralisation model which suggests the margins of the dyke as being the most prospective for the accumulation of sulphide minerals.
The lower sulphide zone in NRC476 matches the position of the modelled EM conductor and is associated with a metal enriched (silver-copper-zinc) sedimentary-volcanic unit. Follow up drilling is planned for the target zone beneath the sulphide-in-gabbro intersection from NRC476.
Follow up drilling has been completed at the Jimberlana North prospect. Sulphide zones were intersected where expected, however metal contents of the sulphides were below previously reported assays at that location. The Jimberlana North prospect has been accordingly reduced in ranking compared to other more prospective targets within the Norseman project area.
North Callisto Prospect
First pass drilling of the North Callisto prospect was undertaken in September as part of an ongoing systematic exploration programme of the area north of the Callisto discovery.
This drilling has identified two new PGE enriched areas associated with the contact between mafic and ultramafic rock units. Drill holes NRC463, NRC466 and NRC470 are in the northern extension of the magnetic (geological) trend that contains the Callisto deposit.
NRC472 is at the southernmost extent of a separate magnetic (geological) trend parallel to the Callisto stratigraphy. Both target horizons are interpreted as highly prospective for the intrusive rock types which host the palladium-nickel sulphide mineralisation at Callisto.
Regional induced polarisation (IP) geophysical surveying is being planned and is due to commence in late October.
IP surveying is useful for delineation of disseminated sulphide mineralisation of the kind found at the Callisto deposit. This program is designed to cover multiple prospects from South Callisto to North Callisto with the intention of developing well constrained and high value drill targets.
