Galileo Mining Ltd’s (ASX:GAL) recent diamond drilling program in the Lantern Area of the Fraser Range Nickel Belt in Western Australia has confirmed nickel prospectivity, with the first occurrence of nickel and copper-rich massive sulphides over a 7-centimetre section of drill core.
Only a limited amount of drilling has been undertaken at the Lantern prospects with Galileo, the first company to explore the area for basement mineralisation.
No previous nickel exploration has occurred on Galileo’s northern Fraser Range tenure, which provides the company with a first-mover advantage on a virgin greenfields property in a new nickel belt.
Of notable importance is the intersection of a 7-centimetre band of primary massive sulphide which assayed 4.6% nickel, 2.2% copper and 0.15% cobalt, demonstrating the ability of the mineralising system at the Lantern prospect to create high-grade nickel and copper sulphides.
"Important step forward"
Managing director Brad Underwood said: “These results are a very important step forward for the ongoing exploration programs at our Fraser Range project.
“For the first time, we have identified a small section of primary massive sulphide with high levels of nickel, copper and cobalt.
“This means we have identified a mineralised system that can produce high-grade nickel and copper.
“Our job now is to focus on those areas that have the potential to hold large accumulations of economic sulphides.
“We currently have two advanced prospects at Lantern South and Lantern East where more drilling is required to follow up on the work completed to date.
“Given that we have confirmed the fertility of the rocks on our tenements, we will also be increasing our efforts to build our earlier stage prospects into drill targets as we look to create a suite of high-quality prospects for drill testing.”
Lantern South prospect
Other notable intersections received for disseminated sulphides from Lantern South prospect include:
- 22.66 metres at 0.19% nickel and 0.14% copper from 132.67 metres including 5.95 metres at 0.36% nickel and 0.29% copper from 134.82 metres.
Downhole EM surveying of reverse circulation (RC) drill holes adjacent to hole LARC013D were previously completed with results limited to near-surface effects due to weathered regolith and cover material.
RC drilling and diamond drill core logging suggest that the best potential for further mineralisation at Lantern South is towards the south of the intrusion where the projected sulphide zone wraps around the intrusion.
Additional RC drilling has been planned beneath and to the south of LARC012 to expand the footprint of mineralisation and to identify those areas with the greatest capacity for higher-grade mineralisation.
Potential within area
The occurrence of high-grade nickel-copper primary massive sulphide within Galileo’s tenements at the Fraser Range is a noteworthy step in the exploration process and demonstrates the potential within the area.
Nickel-copper sulphide mineralisation of this type is very rare within the Fraser Range and with few other known locations including the Nova mine site, the Silver Knight deposit, and the Mawson prospect.
RC drilling of the new conductive targets at Lantern East is scheduled for late November subject to drill rig availability.
