Rumble Resources Ltd (ASX:RTR) (FRA:2OZ) has welcomed strong assay results from the maiden drilling program completed by joint venture partner AIC Mines Ltd (ASX:A1M) (OTCMKTS:IAUFF) at Lamil Gold-Copper Project in WA’s Paterson Province.
Results have confirmed primary copper sulphide mineralisation with low-level gold and multi-element pathfinder anomalism.
According to Rumble, these results are highly encouraging, particularly given the wide spacing of the drilling program.
Multiple narrow intervals of primary copper sulphide mineralisation with low-level gold and multi-element pathfinder anomalism were intersected in the final two diamond drill holes of the program spaced 800 metres apart along the eastern flank of the Lamil Main Dome.
Results at hole 20ALDD0006:
- 1.41 metres at 0.05% copper from 98.66 metres; and
- 2.21 metres at 0.04% copper from 219.75 metre.
Hole 20ALDD0007 returned:
- 4.92 metres at 0.11% copper from 163.08 metres;
- 0.40 metres at 0.18% copper from 232.37 metres; and
- 1.59 metres at 0.12% copper from 237.10 metres.
In line with earn-in and exploration agreement signed by the companies, AIC can earn a 50% interest by spending $6 million over 4 years.
Thereafter AIC can earn a further 15% by spending $4 million over one year if Rumble elects not to start contributing.
Copper mineralisation, together with anomalous pathfinder elements including gold, silver, lead, zinc, bismuth and sulphur, is associated with a significant zone of alteration defined by elevated sodium.
Potential to host mineralisation
AIC’s managing director Aaron Colleran said: “The primary objective of this first campaign – to confirm prospective basement rocks beneath relatively shallow cover – has been achieved.
“The identification of large-scale structures together with evidence of extensive alteration, anomalous pathfinder geochemistry and most importantly confirmation of primary copper sulphides, in first pass wide-spaced holes, has exceeded our expectations.
“This campaign reinforces our belief that the Lamil Project has the potential to host significant mineralisation.”
The maiden drilling program consisted of 68 wide-spaced aircore/reverse circulation drill holes and seven diamond drill holes for 2,840 metres for a total combined metreage of 11,431 metres.
Initial results indicate coincident low-level multi-element pathfinder geochemical anomalism, including gold and copper, extending along the central-eastern flank of the Lamil Main Dome for at least 2 strike kilometres in association with a coherent zone of hydrothermal alteration defined by elevated sodium.
The ‘alteration cell’ is interpreted to represent albite alteration, a key feature of many of the known mineral systems of the Paterson Province including the world-class Telfer Gold-Copper Deposit, just 30 kilometres to the east of Lamil.
The geological and geochemical information provided by this drilling is very encouraging and has exceeded Rumble’s expectations.
Results from this work, combined with the results from recently completed infill and regional soil sampling and ground gravity surveys, are being used to prioritise targets for follow-up drill testing during the 2021 field season.
Seven additional RC and diamond drill holes are planned to infill and extend the Phase 1 program at the Lamil Dome and to test newly identified targets over the broader project area.
Heritage surveys are scheduled for completion in mid-April 2021 and drilling will restart shortly thereafter dependent on drill rig availability.
