Rumble Resources Ltd (ASX:RTR) joint venture partner AIC Mines Ltd has returned encouraging reverse circulation (RC) drilling results from the Lamil Gold-Copper JV Project, 30 kilometres west of the Telfer Gold-Copper Mine in the highly prospective Paterson Province of Western Australia.
Rumble and AIC both have a 50% interest in the project, which is one of the most highly endowed yet under-explored mineral provinces in Australia and hosts the world-class Telfer Gold-Copper Mine and the Nifty Copper Mine and significant copper-gold discoveries at Winu and Havieron.
AIC drilled a total of 6,992 metres, testing five targets: Lamil Dome, Goodenia, Sundew, Flame Pea North and Flame Pea South.
The project covers 1,280 square kilometres capturing a covered belt of Yeneena Supergroup rocks (which host mineralisation at both the Telfer and Nifty mines) bound by two deep penetrating, belt parallel NNW trending structures.

One of the main highlights was a single diamond hole testing a gravity anomaly beneath a halo of base metal anomalism at the Goodenia Prospect, which returned broad intersections of elevated zinc and lead mineralisation, including:
- 6 metres grading 0.09% zinc and 0.03% lead from 322 metres; and
- 6 metres grading 0.21% zinc and 0.09% lead from 474 metres
Intervals of anomalous copper and gold intersected in three wide-spaced RC holes at the previously untested Sundew target:
- 5 metres grading 0.13% copper from 152 metres; and
- 3 metres grading 0.16% copper from 160 metres
- 40 metres grading 0.04% copper from 120 metres including 4 metres grading 0.12% copper from 128 metres
Diamond drilling at Goodenia
The Goodenia Prospect saw a 697-metre hole drilled to test a coincident magnetic and gravity anomaly underlying elevated base metal anomalism. Intervals of zinc and lead mineralisation were intersected down the length of the hole. Significant intersections include:
- 3 metres grading 0.1% lead and 0.016% zinc from 186 metres;
- 6 metres grading 0.09% zinc and 0.03% lead from 322 metres, including 0.5 metres grading 0.14% zinc and 0.063% lead from 323.5 metres;
- 6 metres grading 0.21% zinc and 0.09% lead from 474 metres, Including 1-metre grading 0.34% zinc and 0.14% lead from 476 metres; and
- 3 metres grading 0.074% zinc and 0.03% lead from 565 metres

A total of four diamond holes were completed along the eastern flank of the Lamil Dome Prospect with the aim of vectoring toward copper sulphide mineralisation associated with the contact zone of extensive mafic intrusive.
Two holes tested the down dip extent of the contact zone between 21ALRC0054, which returned 1-metre grading 2.26% copper and 51ppb gold from 90 metres, and 20ALDD0006, which returned 1.4 metres grading 0.05% copper.
The two holes following up the better results continued to return elevated copper and gold over narrow intervals, as detailed below:
Hole 22ALDD0008
- 1-metre grading 0.11% copper from 80 metres; and
- 2 metres grading 0.02% copper from 505 metres.
- 0.65 metres grading 0.05% copper from 139.6 metres; and
- 0.7 metres grading 0.09% copper and 0.1% lead from 207.3 metres.
Drilling has defined a central zone of notable intervals over about two kilometres of strike associated with strong alteration. Down-hole electromagnetic surveys (DHEM) conducted in holes 22 ALDD008 and 22ALDD009, did not detect any conductors.
Reverse circulation at Sundew
Six holes were drilled at the Sundew Prospect on a 750-metre spacing to test for potential Telfer style gold-copper mineralisation beneath a multi-element soil anomaly.
This anomaly coincided with an interpreted antiform composed of the prospective Malu and Isdell formation rocks (including the Telfer Member – host to the Telfer Gold mine), adjacent to the regionally significant Parallel Fault.
Intervals of elevated copper and gold were intersected in three holes closest to the axis of the antiform, as detailed below.
Hole 22ALRC0095
- 5 metres grading 0.13% copper from 152 metres; and
- 3 metres grading 0.16% copper from 160 metres.
- 8 metres grading 0.03% copper from 112 metres.
- 4 metres grading 0.02% copper from 176 metres.

12 holes at Flame Pea
At the Flame Pea South Prospect, 12 holes were completed testing significant magnetic anomalies on the western limb of an interpreted regionally extensive anticline.
Two holes targeting a discrete magnetic anomaly under Permian cover at the southern portion of the targets intersected elevated copper and gold.
Hole 22ALRC0111
- 1-metre grading 0.04% copper from 120 metres.
- 40 metres grading 0.04% copper from 120 metres, including 4 metres grading 0.12% copper from 128 metres.
