Rumble Resources Ltd (ASX:RTR, OTC:RTRFF) is in the clear to commence drill testing of the previously untested Navajoh Southeast Trend within the growing Earaheedy Base Metals Project, 110 kilometres north of Wiluna in WA.
This is after the multi-element explorer received heritage clearance from the Wiluna Native Title Holders, the Tarlka Matuwa Piarku Aboriginal Corporation (TMPAC), for a major reverse circulation (RC) drilling campaign targeting high-grade feeders.
Drilling contracts have been awarded, with drill rigs to be mobilised in the coming weeks.
Multiple targets
The planned drilling program will target multiple new gravity lows along the nine-kilometre Navajoh Southeast Trend.
An airborne gravity survey flown late last year had highlighted a strong association between these gravity lows and higher-grade zinc-lead feeder faults at the Tonka and Navajoh prospects.
The Navajoh Southeast Trend is southeast of the Tonka-Navajoh mineralised footprint.
Additionally, surface geochemistry along the Navajoh Southeast Trend returned strong continuity of zinc-lead in soil anomalism over the nine-kilometre untested strike.
Location of Earaheedy's deposits, contoured mineralised footprint, open untested prospects and trends.
Forward plan
Rumble‘s strategy for the Earaheedy Project is to continue to define the full extent of the emerging zinc-lead-silver base metal system within the 45-kilometre Navajoh Unconformity Unit.
The company plans to focus on extending existing and discovering new high-grade feeders such as Kalitan, Chikamin, Colorado and Magazine within E69/3464 tenement and the untested Sweetwater and Navajoh Southeast trends within the 100%-owned E69/3787 and E69/3862.
As well, it has plans to commence preliminary scoping level studies on the Chinook, Tonka and Navajoh deposits.
Next steps
Aside from the Navajoh Southeast Trend campaign, Rumble plans to begin discovery drilling this month to locate new high-grade feeder faults from advanced targets highlighted along the 12-kilometre Sweetwater Trend.
Other workplans on the agenda include:
- Resource definition drilling: Infill RC, diamond and sonic drilling to improve the confidence and classification of the existing Earaheedy mineral resource estimate;
- Metallurgical studies: Diamond and sonic drilling variability and composite samples will be collected to confirm the simple and conventional flowsheet, and further improve the flotation performance. Additionally, value adding beneficiation work such as dense media separation and ore sorting will commence once the required volumes of cored material have arrived from site; and
- Scoping studies: Work will commence in late 2023, which will review some of the early development scenarios/options.
