Galileo Mining Ltd (ASX:GAL) has received broad intersections in drilling at the Lantern prospect within Western Australia’s Fraser Range Nickel Belt that expand the Lantern South nickel-copper footprint.
The best result in the reverse circulation (RC) campaign was 41 metres at 0.19% nickel and 0.14% copper from 55 metres including 10 metres at 0.26% nickel and 0.23% copper from 78 metres in hole LARC002.
Anomalous gold of up to 88 ppb, platinum up to 75 ppb and palladium up to 88 ppb have been returned associated with nickel and copper and these are significant indicators of magmatic nickel-copper systems.
The RC drilling further defines the target ultramafic rock unit at Lantern South with strong potential for additional mineralisation.
Encouraged by early results
Managing director Brad Underwood said: “This is a great result from only our second RC drilling program in the area.
“We have expanded the nickel sulphide target zone and are developing our understanding of the mineralisation in preparation for further drilling.
“Lantern South is one of several exciting prospects within our Fraser Range project area and it is highly encouraging that we are hitting nickel and copper at this early stage of exploration.”

RC drilling was undertaken last month to expand the known area of mineralised ultramafic target rocks at Lantern South, to investigate the stratigraphy at Lantern East and to establish pre-collars for a diamond drilling program which has subsequently been completed.
Previous nickel and copper intersected at a similar depth in LARC002 was found to be related to sulphide mineralisation at depth in LARC003 and LARC013D, which suggests that sulphide mineralisation will exist beneath LARC012.
The sulphide target zone on the western margin of the ultramafic unit is open further to the south.
There were 416 metres of diamond core tails drilled into three areas with two of the three diamond drill holes intersecting significant sulphide.
Logging of diamond drill core has been undertaken and samples sent to the laboratory with assays pending but due to a substantial build-up of samples, it is anticipated that assays will take a minimum of four weeks to be returned.
The logging of diamond core has provided a large amount of structural and lithological data which will assist in building up the exploration model for the area.
Underwood added: “Our recent diamond drill program intersected more sulphides and the core samples from that program are now at the laboratory with assay results pending.”
Upcoming work programs planned at Lantern include:
- Assaying of diamond drill core, petrographic examination of rocks and analyses of sulphide mineralogy including nickel tenors;
- Integration of diamond drilling data with geological exploration models; and
- Drill testing of sulphide targets at Lantern South and revised modelled conductor at Lantern East.
