Galileo Mining Ltd (ASX: GAL) has intersected disseminated copper and nickel sulphides in all six RC holes completed on its 100% owned Norseman project in Western Australia.
Ten drill holes for 1,568m were completed within the Norseman project area with six holes drilled on Galileo’s Mine Lease prospect.
Managing Director Brad Underwood said laboratory assays are estimated to be available in three weeks for priority drill hole NRC266 and in approximately eight weeks for the remaining drill holes.
We continue to receive highly encouraging results from our Norseman project with disseminated nickel-copper sulphides intersected in every drill hole undertaken at our Mine Lease prospect,” Mr Underwood said.
“Previous drilling hit nickel-copper-palladium and, with sulphide concentrations increasing in the current drilling, we are hoping for improved grades when the assays are returned from the laboratory.
“We cannot tell from visual observation whether the sulphide contains palladium, platinum, or gold, and it is up to the laboratory to determine whether we are close to an economic discovery.
“The Mine Lease prospect is open in all directions however the sulphides appear to be increasing towards the east. This will be the area of immediate focus with a 2,000 metre follow up RC drill program planned to begin once pending assays are returned and drill sites have been finalised.
“The first round of RC drilling at the Jimberlana and Mission Sill prospects has also been completed. Four RC holes were drilled adjacent to previous aircore drilling with site locations constrained by existing tracks. Sulphides were logged in three of the four drill holes and a lot of further work is required at these prospects.
“We look forward to updating the market with drill assays and will be liaising with the laboratory to expedite the delivery of results.”
Six holes for 1,142 metres were drilled on the Norseman Mine Lease prospect. The target is a mineralised sulphide unit developed at the base of an ultramafic sill where it overlies a sediment. Each drill hole exhibited a consistent geological pattern in downhole logging – weak disseminated sulphides/disseminated sulphides/weak disseminated sulphides/(ultramafic)/sediment.
Drill holes were completed on two east-west lines spaced 50 metres apart with a 50-metre drill spacing along the lines.
Drill hole NRC266 recorded the widest interval of sulphide mineralisation with sulphide abundance increasing to the east.
Jimberlana and Mission Sill prospects – first round RC drilling
An initial RC drill program was undertaken at the Jimberlana and Mission Sill prospects. Drill holes were placed adjacent to previous aircore drilling with site locations limited to existing tracks. Four holes were completed at three locations for a total of 426 metres.
Forward work programme at the Norseman project
1) Assaying of all drill holes from the current RC programme
2) Down hole EM surveying of selected drill holes to assist with next stage of drill targeting
3) Petrography of selected samples to determine precise rock classifications (as a guide to mineral fertility and prospectivity)
4) 2,000 metre RC drill programme to target the mineralisation within the Mine Lease sulphide zone
5) RC drilling of EM and geochemical targets at the Jimberlana prospect
6) IP and surface EM surveying of geological and geochemical targets at the Mission Sill prospect
7) Aircore drilling of 4 km untested prospective contact zone at the Mission Sill prospect 8) RC drill testing of geophysical and geochemical targets at the Mission Sill prospect
