Earaheedy Project - Emerging World Class Base Metal System
Since the exciting Chinook discovery in April 2021, drilling has rapidly uncovered an emerging world class Zn-PbAg-Cu metal system with provincial scale potential. Within tenement E69/3464, the Zinc sulphide dominant mineralisation occurs within two well defined deposits (Chinook and Tonka) with a combined strike of 13km and 2km cross strike, which remain open in all directions and at depth ( see image 1 ). Higher-grade zones within the mineralised Navajoh Unconformity Unit and underlying dolomite (Sweetwater Well Dolomite – formerly Navajoh Dolomite) are associated with multiple inferred feeder faults/zones that are oriented both northwest and east-west.
-
The Tonka and Navajoh Prospects are linked by higher-grade east-west feeder fault zones within a large 8km x 2km northwest trending mineralised footprint that remains open in all directions. Two mineralised feeder faults/zones (Colorado and Magazine) have been outlined to date, with the opportunity to define multiple additional zones - see image 1.
-
The Chinook Prospect is a large 5km by 2km northwest trending mineralised footprint which remains open in all directions. Higher-grade zones associated with both northwest and east-west trending feeder structures with two principal feeder zones (Kalitan and Spur) interpreted to date - see image 1.
-
The Earaheedy Project has provincial scale potential with the newly granted 100% owned E69/3787 & E69/3862 tenements providing :
-
A further 23km’s of potential unconformity type mineralised strike along the Sweetwater and Navajoh Southeast trends, which is yet to be drill tested. These trends have increased the overall strike of this unconformity mineralised horizon to 42km’s. There is likewise potential to discover new high grade mineralisation styles in the untested underlying geological formations ( see image 3 ) including the Iroquois Dolomite where Strickland Metals announced the intersection of high-grade zinc intersections (refer ASX announcement STK – 14/10/21) – see image 1.
-
The broad Iroquois Dolomite unit occurs over a 35km strike and is interpreted to surface within the recently granted E69/3787 (100% RTR) which also remains to be drill tested – see Image 1.

Sweetwater Trend E69/3787 - RTR 100% - RC Drilling Commenced
Drilling by Rumble has defined extensive Zn-Pb-Ag mineralisation on the boundary between E69/3464 and the recently granted E69/3787 (100% Rumble) tenure, which is host to the 15km long untested Sweetwater Trend.
Excitingly, Rumble has now received the necessary heritage clearances from the Wiluna Native Title Holders, the Tarlka Matuwa Piarku Aboriginal Corporation (TMPAC) to commence RC drill testing a 6km section, which hosts the potential western continuation of the large Chinook Zn-Pb deposit. Rumble has submitted a heritage survey request for clearance of the remainder of the Sweetwater Trend and the 8km long Navajoh Southeast Trend that also remains untested.
RC drilling has commenced targeting shallow higher-grade domains associated with potential mineralised feeder structures in the Navajoh Unconformity Unit within E69/3787. The only two shallow historic RC holes previously drilled along the Sweetwater Trend intercepted Zn-Pb mineralisation, 12km to the west of Chinook (see Image 2).

Iroquois Carbonate Trend E69/3787 - RTR100% - Image 1
Rumble has completed a new interpretation of the Iroquois Dolomite unit which is interpreted to surface within the recently granted E69/3787 (100% Rumble) and has over 35km of untested strike . Rumble has received heritage clearances to start regional aircore reconnaissance drill testing along two sections of the Iroquois Carbonate Trend. Very limited drilling conducted in the 1970’s intercepted shallow Zn-Pb mineralisation in the Iroquois Carbonate Unit including:
-
RWAC002 – 9m @ 0.97% Zn + Pb (from 60m to EOH )
-
RWAC031 – 1m @ 1.09% Zn + Pb (from 32m to EOH )
These intercepts are along strike from Strickland Metals Ltd (refer ASX: STK announcement - 14/10/2021) high grade intercepts at the Iroquois Prospect, which included 23m @ 5.5% Zn+Pb from 108m and 12m @ 5.4% Zn+Pb from 58m, and emphasizes the potential for further near surface discoveries in the region – see Image 1.

Earaheedy Project – Multiple Mineralisation Styles
==> picture [82 x 71] intentionally omitted <==
The overall geological deposition model for the Earaheedy Base Metal Province is continually evolving with some five (5) styles of mineralisation identified (see image 3).
Rumble has confirmed at least four (4) of these styles have been defined within the Earaheedy Project and based on recent drilling completed by Strickland Metals (refer ASX: STK announcement – 14/10/2021), the likelihood of significant Iroquois Dolomite hosted mineralisation below Chinook, Tonka-Navajoh and near surface along the Iroquois Carbonate Trend is very high.
The current drilling has outlined laterally extensive flat lying unconformity related zinc-lead-silver sulphide mineralisation at the Chinook, Tonka-Navajoh Prospects (mineralisation styles 1 and 2 – image 3).

2022 - 50,000m Drilling Program – Progress Update
==> picture [82 x 71] intentionally omitted <==
A large scale 50,000m commenced in January 2022 with over 26,000m of RC drilling already completed. Unfortunately, as seen in 2021, industry-wide delays in assay turnaround times have continued and the Company currently has over 11,000 samples pending from intervals selected based upon visual and XRF information.
The RC drilling has been focused on the Tonka Prospect targeting high-grade Zn-Pb domains at the newly identified east-west trending Colorado Zone.

Initial Exploration Target
==> picture [82 x 71] intentionally omitted <==
Rumble’s Zn-Pb exploration target at the Earaheedy Project is between 100 to 120 million tonnes at a grade ranging between 3.5% Zn-Pb to 4.5% Zn-Pb Sulphide. The exploration target is at a shallow depth (120m), and over 40kms of prospective strike (completely open) has been defined within the Earaheedy Project. The potential quantity and grade of the exploration target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The exploration target, being conceptual in nature, takes no account of geological complexity, possible mining method or metallurgical recovery factors. The exploration target has been estimated in order to provide an assessment of the potential for large-scale Zn-Pb deposits within the Earaheedy Project. The exploration target has been prepared and reported in accordance with the 2012 edition of the JORC Code.
| Earaheedy Zn-Pb Project – Exploration Target | ||
| Range | Tonnes | Grade |
| Lower | 100,000,000 | 3.5% Zn + Pb Sulphide |
| Upper | 120,000,000 | 4.5% Zn + Pb Sulphide |
Table 1: Near surface exploration target down to 120 metre - shallow depth
The exploration target is based on the current geological understanding of the mineralisation geometry, continuity of mineralisation and regional geology. This understanding is provided by an extensive drill hole database, regional mapping, coupled with understanding of the host stratigraphic sequence. Included in the data on which this exploration target has been prepared are results from over 50,000m of drilling completed by Rumble. Historic drilling includes sixty-four (64) holes completed within the project area (E69/3464) by previous explorers (refer historical exploration results in previous ASX announcements dated 5 February 2019 and 12 October 2017, 23[rd] January 2020 which continue to apply and have not materially changed).
Some of the considerations in respect of the estimation of the exploration target include:
-
Drilling results have demonstrated strong continuity of shallow, flat lying sulphide mineralisation.
-
Over 42km’s of prospective strike and open (refer images 1 & 6).
-
Minimum 600m of width based on shallow 7.5° and shallow depth to 120m, based on drilling results.
-
True width (thickness) of mineralisation up to 51 metres received in drilling results: and
-
Specific gravity (SG) of 2.5 (world average SG of sandstone – not accounting for metal).
The Company intends to test the exploration target with drilling and this further drilling is expected to extend over approximately 12 months. Grade ranges have been either estimated or assigned from lower and upper grades of mineralisation received in drilling results. A classification is not applicable for an exploration target.
About the Earaheedy Project
The Earaheedy project is located approximately 110km northeast of Wiluna, Western Australia. Rumble owns 75% of E69/3464 and Zenith Minerals Ltd (ASX: ZNC) owns 25%. Rumble has two contiguous exploration licenses, EL69/3787 and EL69/3862 that are held 100%.
Since the major Zn-Pb-Ag-Cu discovery in April 2021, scoping and broad spaced infill drilling has rapidly uncovered an emerging world class scale Zn-Pb-Ag-Cu base metal system, with the drilling continuing to make discoveries and new multiple large-scale targets evolving.
The Project covers 42km of the Navajoh Unconformity Unit’s prospective strike which remains untested and open.
