Rumble Resources Limited announced 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. Broad spaced partial leach sampling on a 1,000m 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 Zn­Pb anomalism over a strike of some 11 km.

The anomalism is inferred to represent the up-dip position of the northeast shallow dipping mineralized 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. Final processing of the airborne gravity gradiometer (AGG) survey data has highlighted the strong correlation between high-grade feeder zones and gravity lows at Tonka-Navajoh. The 1949 line km AGG survey was flown on approximately 200m flight line spacings at a nominal height of 80m.

Three principal mineralising structural orientations were recognised ie. northwest, east-west and northeast faults/trends. The later stages of the Lockeridge Fault system development, which is spatially associated with the Celia Lineament (a regionally extensive major shear corridor in the underlying Archaean Yilgarn Craton), has reactivated many of these earlier structures.

The Colorado and Magazine Feeder Faults with their associated broad and higher-grade Zn-Pb mineralisation (based on broad 200m by 100m drill pattern) are positioned in a broad gravity low, which remains open to the east. Note, there are a multitude of opportunities to extend and upgrade the higher-grade Zn-Pb mineralisation with the many gaps that remain untested along strike of the Colorado and Magazine feeder zones. Large, generally east-west to northeast, gravity lows are associated with an additional four (4) inferred, partly drilled feeder faults at Navajoh.

These gravity lows are open to the east, northeast and potentially to the west, where the drill spacing is 900m and 500m apart. The strong association between gravity lows and higher Zn-Pb grades is interpreted to be the result of strong dissolution and the unconsolidated lithological variability of the dominant mineralised host (Navajoh Unconformity Unit), which has developed along the feeder fault zones. Thus, the Navajoh Unconformity Unit is less dense.

The recent soil geochemistry has demonstrated continuity of the unconformity related Zn-Pb mineralisation extending southeast from Navajoh, whilst the AGG survey has defined multiple large northeast trending gravity low targets that are inferred as potentially new higher-grade feeder faults. Image 1 highlights both surveys and the gravity low targets generated. Of note, the interpreted orientation of the gravity low targets rotate from east-west at Tonka-Navajoh, to northeast along the Navajoh Southeast Trend.

The northeast orientation reflects the same interpreted orientation of the recently discovered Iroquois Zn-Pb Prospect (Strickland) which lies a further 5km south of the E69/3787 (100%RTR) boundary. The Iroquois Zn-Pb Prospect returned strong mineralisation, including 23m at 5.5% Zn + Pb and 12m at 5.4% Zn + Pb. The dominant mineral is sphalerite (ZnS) with the Zn/Pb ratios greater than 5:1. Following the recent drill programs completed by Rumble, the Tonka-Navajoh Zn-Pb mineralisation now extends over 11km (37% increase) in length and is up to 3km in width.

RC drilling at the Colorado Feeder Fault intersected high-grade Zn-Pb mineralisation, further supporting the continuity of the feeder zone. Better results included: 8m at 5.64% Zn + Pb from 213m (EHRC562); Inc. 3m at 11.94 % Zn + Pb from 214m; 8m at 3.90% Zn + Pb from 212m (EHRC556); Inc. 2m at 7.13% Zn + Pb from 214m; 3m at 7.08% Zn + Pb from 129m (EHRC551); Inc. 1m at 18.18 % Zn + Pb from 131m; Excitingly, RC drilling has also delineated an emerging new, Zn sulphide dominant, high grade feeder zone 800m; northwest of the Colorado Feeder Fault. Initial results include.

5m at 5.38% Zn + Pb from 97m (EHRC580), within a broader zone of 23m at 2.30 % Zn + Pb from 95m. The Magazine Feeder Fault continued to return strong continuity with shallow high grade Zn­Pb sulphide mineralisation intersected, including: 8m at 3.34% Zn + Pb from 58m (EHRC565); Inc. 4m at 5.60% Zn + Pb from 58m; 5m at 3.85% Zn + Pb from 85m (EHRC563); Inc. 3m at 6.00% Zn + Pb from 85m. Exploration 2023: Drilling has been completed to deliver a maiden JORC mineral resource estimate (MRE), which is now due to be reported in the first half of 2023; Drilling planned for 2023; Continue to test and extend high-grade feeder structures at Chinook, Tonka and Navajoh Prospects; Target newly interpreted high-grade feeder targets along the untested 15km Sweetwater and 9km Navajoh Southeast trends.

The Earaheedy Project is located approximately 110km northeast of Wiluna, Western Australia. Rumble owns 75% of E69/3464 and Zenith Minerals Ltd. owns 25%. Rumble has two contiguous exploration licenses, EL69/3787 and EL69/3862 that is held 100% RTR.

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 interpretative geology and drilling continuing to make new discoveries and highlight multiple large-scale deposit targets. The focus of the geological team remains the targeting, delineation and extension of the high-grade Zn-Pb feeder zones that continue to be discovered contemporaneously with the evolving structural and geological understanding. The recent discovery of the high-grade Chikamin Feeder Zone and the results of the recent geophysical and geochemical surveys has greatly increased Rumble's confidence in defining multiple new high grade mineralized feeder zones within the Earaheedy Project's boundaries.
