Rumble Resources Limited (ASX: RTR) (“Rumble” or “the Company”) is pleased to announce the latest round of high- grade Zn-Pb RC drilling results from the Tonka Prospect, plus the delineation of multiple new gravity low targets which potentially may represent new high-grade feeder faults within the 11km Tonka-Navajoh mineralised footprint and over 9km of drill untested strike southeast of Tonka-Navajoh deposit (Navajoh Southeast Trend). The new high priority targets were interpreted following recently completed soil geochemical and airborne gravity gradiometer surveys at the Earaheedy Project, located 110km north of Wiluna, Western Australia.
Geochemistry and Airborne Gravity – Multiple New Feeder Targets
- Surface geochemistry and airborne gravity surveys have defined multiple high- grade feeder zone targets at Tonka-Navajoh Prospects and the newly defined Navajoh Southeast Trend
- Interpretation of the recent airborne gravity survey has highlighted a strong association between gravity lows and higher-grade Zn-Pb feeder faults at the Tonka and Navajoh Prospects
Navajoh Southeast Trend E69/3787 (100% RTR) – 9kms of untested strike
- Surface geochemistry along the Navajoh Southeast Trend returned strong continuity of Zn-Pb in soil anomalism over 9km of untested strike
- Airborne gravity highlighted numerous gravity low targets that potentially represent multiple new high grade feeder faults along the 9km of strike
- These exciting new feeder targets are planned to be drill tested in early 2023
Tonka-Navajoh Prospect – over 11kms of Zn-Pb mineralisation defined
- Recent drilling has now extended the strike of the Tonka-Navajoh mineralisation to over 11km; a 37% increase in length.
- Within this large mineralised footprint numerous gravity low targets that could represent new high grade feeder faults or extensions to existing feeder faults have been identified
RC Drilling - Tonka-Navajoh
- The Tonka-Navajoh Zn-Pb mineralised footprint is over 11km along strike and up to 3km cross strike and remains open along strike and down dip
- The Colorado Feeder Fault continues to deliver high-grade results including:
- 8m @ 5.64% Zn + Pb from 213m (EHRC562)
- Inc 3m @ 11.94 % Zn + Pb from 214m
- 8m @ 3.90% Zn + Pb from 212m (EHRC556)
- Inc 2m @ 7.13% Zn + Pb from 214m
- 3m @ 7.08% Zn + Pb from 129m (EHRC551)
- 8m @ 5.64% Zn + Pb from 213m (EHRC562)
- A newly defined mineralised feeder structure, 800m northwest of the Colorado Feeder Fault has returned:
- 5m @ 5.38% Zn + Pb from 97m (EHRC580)
- The Magazine Feeder Fault has likewise delivered further high-grade results including:
- 8m @ 3.34% Zn + Pb from 58m (EHRC565)
- Inc 4m @ 5.60% Zn + Pb from 58m
- 5m @ 3.85% Zn + Pb from 85m (EHRC563)
- Inc 3m @ 6.00% Zn + Pb from 85m
- 8m @ 3.34% Zn + Pb from 58m (EHRC565)
Geochemical and Geophysical Exploration – Potential New Targets

Soil Geochemistry – Navajoh Southeast Trend - Image 1
Broad spaced partial leach sampling on a 1000m by 200m pattern completed southeast of Navajoh (Navajoh Southeast Trend) in conjunction with previous orientation partial leach sampling (same methodology) at the Navajoh Deposit, has delineated strong continuity of Zn–Pb anomalism over a strike of some 11 km.
The anomalism is inferred to represent the up-dip position of the northeast shallow dipping mineralised Navajoh Unconformity which hosts the Tonka-Navajoh and Chinook Zn-Pb deposits.
Of significance, the tenor of 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.
The depth of cover (including late lacustrine sediments) is estimated to be 10 to 20m under the recently defined Zn- Pb soil anomalism, hence the overall lower elemental response. However, the partial leach sampling and assaying methodology was successful in delineating the up-dip position of the mineralised unconformity.

Drilling Commenced at Viani in Fiji
HIGHLIGHTS
- The Phase 1, three-hole diamond drilling program has commenced at the Viani Project, Fiji and will test for extensions to the quartz vein gold mineralisation at depth.
- Phase 1 is expected to be completed in early 2025, with plans for additional drilling under the same program dependent on the initial results
- The Viani Project (SPL1513) covers an area of approximately 200km2 and is largely underexplored.
- At the Dakuniba prospect within Viani, low sulphidation epithermal high-grade gold mineralisation has been mapped over >3km strike length.
- Diamond drilling completed by Japan International Cooperation Agency (JICA) in 1995 to 1997 intersected high-grade gold in low sulphidation epithermal quartz veins, including 0.6m @ 27.6 g/t Au.
Alice Queen’s Managing Director, Andrew Buxton said,
With drilling underway, Alice Queen is positioned to test the epithermal gold-style mineralisation identified in historic drilling at the Viani Project. Weather permitting, we anticipate completing the Phase 1, three-hole diamond drilling program in early 2025. Following this, our exploration team will mobilise the drill rig to the Sabeto Project in Fiji to maintain the momentum of this campaign. To deliver timely results to shareholders, we intend to accelerate the analysis of the drill core at ALS Brisbane.”

Details
Geology
The geology of the Viani Project (SPL 1513) comprises olivine basalts and volcaniclastics of the Natewa Volcanic Group which are intruded by andesite sills and dykes. In the 1940s, gold mineralisation was found by local prospectors near the village of Dakuniba. At Dakuniba, low sulphidation style epithermal gold occurs in quartz veins, and silicified rocks along a 3km long NE trending zone.
In 1995-1997, Japan International Cooperation Agency (JICA) drilled six diamond holes at Dakuniba and intersected high-grade gold in chalcedonic, crustiform, colloform banded quartz veins at depths of 50m to 100m below surface (i.e. MJVFV-5 intersected 2.2m @ 11.3 g/t Au, incl 0.6m @ 27.6 g/t Au at 121m downhole). This high-grade gold mineralisation is open in all directions.
Proposed Drill program
The initial Phase 1 drill program at Viani (see Table 1) will comprise three diamond drillholes designed to test continuity to the epithermal gold mineralisation previously intersected in JICA drillhole MJVFV- 5 (2.2m @ 11.3 g/t Au) (see Figure 2). The drilling will test for extensions to the gold mineralisation at depth and along strike.
