Rumble Resources (RTR) has intercepted a major feeder fault zone at its Chinook prospect within the Earaheedy project, Western Australia.

The project is located northeast of Wiluna and is majority owned by Rumble, with fellow ASX-lister Zenith Minerals (ZNC) holding a 25 per cent stake.

Chinook is one of four main prospects within the project where the company has been undertaking scoping drilling, and identified a new zone titled Tonka last week.

Most recently at Chinook, the top of a large-scale sub-vertical feeder fault zone was intersected in one drill-hole which returned a broad zone of mineralisation including 84 metres at 1.84 per cent zinc and lead from 151 metres with multiple intersections.

Within this zone were grades of copper and silver including four metres at 1.5 per cent copper with 6.1 per cent zinc and lead, and 23.6 grams per tonne silver from 204 metres.

According to the company, the discovery of copper and silver supports the interpretation of metal zonation within the project area, with copper reflecting the “hotter” portion of the system.

The mineralised footprint at Chinook is 4.1 kilometres along strike and 1.9 kilometres down dip, remaining open in all directions.

Additionally, at the Navajoh prospect, first pass drilling has delineated flat lying unconformity style zinc-lead-silver mineralisation, which the company said appears similar to the Chinook and Tonka discoveries.

Rumble Resources’ Technical Director Brett Keillor said the results to date further confirm the potential of a very large-scale zoned base metal system.

“Ultimately, the flat lying regionally extensive unconformity related zinc-lead-silver mineralisation…. delineated at the Chinook, Tonka and now Navajoh prospects potentially represents the large outer metal halo zones of a world class base metal system that lies within the Earaheedy Project and underlying geological formations.”

Moving forward, diamond core drilling has commenced at both Chinook and Tonka, with RTR looking to delineate the structural and geological controls of both the flat northeast dipping unconformity related and potential high angle feeder fault zones.

Reverse circulation drilling is also scheduled to continue at Navajoh, to define the limits of the mineralisation and infill within the discovery areas.

The company has also applied for a contiguous exploration licence and if granted, drilling is planned in the northwest and west from the area that hosts Chinook, which will open up a further 12 kilometres of strike.

Shares last traded at 36.5 cents on December 20.
