Earaheedy Project Mato Discovery Confirmed with Further High-Grade Zn-Pb Mineralisation
Rumble Resources Ltd
Assay results from the remaining six (6) drill holes of the Mato RC drilling program have confirmed Mato as a significant new Zn-Pb sulphide discovery with the potential to add substantially to the existing pit constrained Inferred Mineral Resource Estimate of 94Mt @ 3.1% Zn+Pb (2% Zn+Pb cut off) at Earaheedy (refer ASX: RTR release 19[th] April 2023).
The latest assay results compliment the original discovery drill hole previously reported (refer ASX: RTR announcement 5[th] October 2023) where EHRC733 returned:
Level 1, 16 Ord Street, West Perth, WA 6005
T +61 8 6555 3980
F +61 8 6555 3981
- 16m @ 5.09% Zn + Pb from 153m
including 10m @ 7.05% Zn + Pb from 157m
The latest results at Mato all come from a single 800m long drill traverse and include:
- 29m @ 3.12 % Zn + Pb from 174m (EHRC734) including 14m @ 5.04% Zn + Pb from 183m
with high-grade zones of 4m @ 10.16% Zn + Pb from 184m
-
and 2m @ 15.58% Zn + Pb from 186m
-
10m @ 2.11% Zn + Pb from 188m (EHRC735) including 3m @ 5.65% Zn + Pb from 190m
-
9m @ 4.89% Zn + Pb from 180m (EHRC738) including 4m @ 7.93% Zn + Pb from 183m
-
21m @ 2.0% Zn + Pb from 214m (EHRC740) Including 5m @ 4.43% Zn + Pb from 220m
All drill hole intersections represent true widths .
The Mato discovery has the hallmarks of a large mineralising system which potentially could enhance the economics and lends further support to Earaheedy developing into a world class base metal camp .

-
Mineralisation along the 800m drill traverse being open in all directions.
-
Closest drilling (single hole only) is 1600m to the east (EHRC730)
-
Exceptional potential for further Zn-Pb sulphide mineralisation up-dip.
-
oMultiple high grade feeder structures have been interpreted. -
The latest results occur 10km west of the Chinook Zn-Pb deposit and drilling along this 10km trend has been limited to three short traverses that are all mineralised.
-
The host and style of the Mato Zn-Pb mineralisation is near identical to the Chinook-Tonka-Navajoh Zn-Pb deposits.
Next Steps for Mato (within E69/3862 – 100% Rumble)
Heritage approval has been granted to allow extensional RC drilling at Mato and includes;
-
Drilling to define up-dip (shallow) and strike extended sulphide mineralisation.
-
Testing potential structural repetition of host Navajoh Unconformity Unit to the south.
Rumble Resources Limited (ASX: RTR) (“Rumble” or the “Company”) is pleased to announce the assay results for the remaining six (6) RC drill holes from an initial scoping program at the newly defined Mato Prospect at Earaheedy (see Figure 1), located 110 km northeast of Wiluna, Western Australia. The drill holes are on the same 800 metre long section where the “discovery” RC hole – EHRC733 returned high grade Zn-Pb mineralisation (refer ASX: RTR announcement 5[th] October 2023).

Mato Prospect RC Drilling – E69/3787 – RTR 100% - refer to Figures 2 to 4
An initial twenty three (23) RC drill hole program has been completed on broad spacings along the previously named Sweetwater Trend. Assays for the first seventeen (17) drill holes were previously reported (see ASX: RTR announcement 5[th] October 2023), along with a high grade intersection in hole EHRC733 which returned:
- 16m @ 5.09% Zn + Pb from 153m
Including an internal higher-grade zone of 10m @ 7.05% Zn + Pb from 157m
==> picture [62 x 53] intentionally omitted <==
The latest assay results at Mato all come from the same 800m long drill traverse (Mato Section 1 – see figures 3 and 4) and include:
-
29m @ 3.12 % Zn + Pb, 2.22 g/t Ag from 174m (EHRC734)
-
including 14m @ 5.04% Zn + Pb, 3.24 g/t Ag from 183m
-
with high-grade zones of 4m @ 10.16% Zn + Pb, 6.53 g/t Ag from 184m
- including 2m @ 15.58% Zn + Pb, 9.95 g/t Ag from 186m
-
-
10m @ 2.11% Zn + Pb, 6.53 g/t Ag from 188m (EHRC735) including 3m @ 5.65% Zn + Pb, 8.97 g/t Ag from 190m
-
9m @ 4.89% Zn + Pb, 4.82 g/t Ag from 180m (EHRC738) including 4m @ 7.93% Zn + Pb, 4.57 g/t Ag from 182m
-
28m @ 1.08% Zn + Pb, 1.47 g/t Ag from 188m (EHRC739) including 5m @ 2.47% Zn + Pb, 2.44 g/t Ag from 210m
-
21m @ 2.0% Zn + Pb, 2.13 g/t Ag from 214m (EHRC740)
-
including 5m @ 4.43% Zn + Pb, 1.78 g/t Ag from 220m
NB. Intersections are zinc sulphide dominant with Zn:Pb ratios greater than 5:1 – refer to Table 1
Drill hole EHRC737 returned low grade Zn – Pb mineralisation (4m @ 1.34% Zn + Pb from 202m) whilst hole EHRC736 failed at a depth of 127m, 50m above the projected zone of interest.

Mineralisation is open in all directions, with the closest RC drill hole (EHRC 730) 1600m east of Section 1 (see figure 2) and previously returned 8m @ 1.53% Zn + Pb from 198m (see ASX:RTR announcement 5[th] October 2023).

The high grade mineralisation at the Mato Prospect is inferred to strike NW, though this interpretation is based only on the single abovementioned drill traverse. Further RC drilling will confirm the strike of the mineralisation. Geological interpretation of the Mato drilling to date has highlighted the potential of feeder zones (cf. Kalitan and Chikaman Feeders at Chinook deposit) controlling the higher-grade mineralisation. Figure 4 presents two inferred faults which may represent mineralised feeder structures.
The highly prospective Mato Mineralisation Corridor (formerly Sweetwater Trend) is highlighted in figure 2. The strike of this mineralisation has now been defined over 10km , i.e., from the western edge of the Chinook Deposit to the Mato discovery traverse or Section 1. Also noted; the historical Sweetwater Prospect lies 4km to the south of the Mato Prospect and has yet to be adequately drill tested.
The recently acquired interest into E69/3815 (see announcement ASX: RTR 24/10/2023) opens up potential for further Zn – Pb deposits west and northwest of Mato (see figures 1 and 2). Geological and geophysical interpretation has inferred up to 30km of additional prospective unconformity style lithologies and mineralisation.

Next Steps for Mato
Recently completed heritage approvals at Mato will allow:
-
RC drilling initially on 800m by 100m spaced lines both west and east along the inferred NW strike of the highgrade (potential feeder) Zn Pb mineralisation.
-
Up-dip drilling along Section 1 to test for shallower Zn-Pb sulphide zones.
-
Extended RC drill sections to test for repetition of high-grade mineralisation based on known sub-parallel reverse faulting to the mineralised Navajoh Unconformity Unit.

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 (see Figure 6). The Project includes tenement (E69/3464), which forms the Rumble Resources Ltd 75% / Zenith Minerals Ltd (ASX: ZNC) 25% Joint Venture (“JV”), E69/3787, E69/3862, E69/4124 and exploration license applications E69/4149, E69/4165 and E69/4178, which are all 100% controlled by Rumble (see Figure 1 and 5).
In addition to the above tenements, Rumble is acquiring (100% RTR) four granted exploration licenses that lie north and northwest of the existing tenure (see Figure 5). These tenements comprise of E69/3815, E69/3842, E69/3889
Rumble announced a major discovery on 19th April 2021 and 2 years later to the day on 19th April 2023, announced a globally significant, pit constrained, maiden inferred Mineral Resource Estimate (MRE) of 94Mt @ 3.1% Zn+Pb and 4.1g/t Ag (at a 2% Zn+Pb cutoff) – refer to ASX release 19[th] April 2023. This maiden MRE confirmed the Earaheedy Project as one of the largest global zinc sulphide discoveries in the last decade. The strength of the MRE is supported by a 41mt of higher-grade resources that could be part of a possible early development scenario, and a much larger 462Mt resource that could potentially be upgraded via beneficiation, providing the project with significant future flexibility.
The Project has exceptional near-term growth potential, with the deposits open in all directions and with the recent tenement additions, the strike potential has significantly increased to over 70km. Drilling by Rumble has focused on the Navajoh Unconformity Unit (host to the current resources) with the aim to find large shallow flat lying sulphide deposits amenable to large scale open cut mining, whilst none of the thick underlying geologically fertile formations which could potentially host high-grade MVT deposits having been tested.
The sheer scale, optionality, location and extraordinary growth potential of Earaheedy could see the Project stamp itself as a world class, multi decade asset and play a key role in the future global renewable energy transition.
