Rumble Resources Limited (ASX: RTR) has received heritage clearances from the Wiluna Native Title Holders, the Tarlka Matuwa Piarku Aboriginal Corporation (TMPAC) to commence drilling of the previously untested 9km Navajoh Southeast Trend on the wholly-owned RTR E69/3787, within the emerging world class Earaheedy Zn-Pb-Ag Project, 110km northeast of Wiluna in Western Australia.
Drilling to commence targeting high-grade feeders
Following a Falcon airborne gravity gradiometry survey completed by the company in late 2022, Rumble reported a strong association between gravity lows and outlined high-grade Zn-Pb feeder faults (eg. Colorado and Magazine Feeders) within the Tonka and Navajoh Deposits.
Additionally, the company defined multiple new gravity lows along the entire 9km Navajoh Southeast Trend which have been interpreted as potential high-grade feeder faults.
Partial leach soil sampling completed over an 11km strike from the Tonka and Navajoh deposits to the southeast boundary of E69/3787 delineated a strong and continuous Zn–Pb anomaly. This anomaly is inferred to represent the up-dip position of the northeast shallow dipping mineralzed Navajoh Unconformity which hosts the Tonka-Navajoh and Chinook Zn-Pb deposits. Significantly, the tenor of this Zn-Pb anomalism in soils over the 9km Navajoh Southeast Trend is equivalent or higher than the up-dip tenor over the already drill defined Navajoh deposit.
Drilling contracts have been awarded with drill rigs mobilizing over the coming weeks. The planned drilling program will target the multiple new gravity lows which could represent high-grade feeder faults along the 9km Navajoh Southeast Trend.
Forward Plan
Rumble‘s Earaheedy Project strategy is to continue to define the full extent of the emerging Zn-Pb-Ag base metal system within the 45km Navajoh Unconformity Unit, with a focus on extending existing and discovering new high- grade feeders (e.g. Kalitan, Chikamin, Colorado and Magazine Feeder Faults) within E69/3464 and the untested Sweetwater and Navajoh Southeast Trends within the wholly-owned E69/3787 and E69/3862, whilst commencing preliminary scoping level studies on the Chinook Tonka, and Navajoh deposits.
Next Steps include:
• Discovery drilling – Aimed at identifying new high grade feeder faults from advanced targets highlighted along the 12km Sweetwater Trend and nine km Navajoh Southeast Trend – Planned to commence in May
• Resource definition drilling – Infill RC, diamond and sonic drilling is planned to improve the confidence and classification of the existing MRE.
• 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 (dense media separation and ore sorting) will commence once the required volumes of cored material have arrived from site.
• Scoping studies – Work will commence late in 2023 on initial supporting scoping studies for the Project, which will review some of the early development scenarios/options.
About the Earaheedy Project
The emerging, world class Earaheedy Zn-Pb-Ag Project is located 110km northeast of Wiluna in Western Australia, with access to major highways, power (gas pipeline), rail, ports, airports and experienced mining workforce.
