EM Survey And AC Drilling Highlight Fraser Range Potential
Galileo Mining Ltd(ASX: GAL) has identified a new a conductive target through assessment of promising initial results from fixed loop EM surveying at the Lantern South prospect in the Fraser Range region of Western Australia.
The survey has revealed a conductive target 1.5km along strike from disseminated sulphides intersected at Lantern South
Results from aircore drilling have also delineated the ultramafic unit at the Lantern South prospect with results of 27m @ 0.18% nickel from 48m and 17m @ 0.17% nickel from 48m.
Managing Director Brad Underwood said RC drilling of shallow targets at the Lantern South prospect is scheduled to commence in July with diamond drilling of the new EM target, and any additional targets to come out of the current EM survey, to begin in August.
“The first results from our current EM survey have shown the presence of a conductor along strike from drilling that intersected nickel and copper sulphide mineralisation,” Mr Underwood said.
“This is an encouraging sign in our exploration for new nickel deposits as conductive targets can be associated with significant amounts of nickel sulphides.
“Our aircore drilling has also outlined the prospective ultramafic unit at Lantern South and this target is now ready for advanced drilling. The next round of drilling is scheduled to commence in July and marks the beginning of an important phase of exploration at our Fraser Range Project.”
The ultramafic unit at Lantern South has near surface dimensions of 260 metres by 100 metres with sulphide mineralisation, intersected by previous RC drilling, occurring on the margin of the unit. Drill testing along the margins of this unit is planned to commence in July.
A new ultramafic unit has also been identified by aircore drilling. This area will require further aircore drilling to define the margins of the unit which are believed to be the most prospective for sulphide mineralisation.
All aircore drilling assays from the recent 8,839 metre (151 drill hole) programme have been received. Drilling showed a variety of surficial conditions with some areas of minimal cover (< 15m), zones of stripped regolith, and a few areas with well developed regolith profiles. Average depth for all aircore drill holes was 59 metres with regolith and cover conditions being considered highly amenable to effective EM surveying.
First pass moving loop EM surveying plans are now confirmed for the southern side of the major Lantern intrusion as well as the Think Big, Backwood and Green Moon intrusions to the north. Ongoing geochemical and petrographical analyses of aircore results aims to assist in determining those areas most prospective for nickel mineralisation.
Upcoming work programs planned at the Lantern Prospect include:
- Completion of fixed loop electro-magnetic (FLEM) surveying of prospective zones defined from aircore drilling and from the 2019 MLEM survey
- First pass moving loop electro-magnetic (MLEM) survey on southern side of major Lantern intrusion
- Petrography and detailed interpretation of aircore drilling results
