Rumble Resources Limited announced that the maiden RC drilling results along the Sweetwater Trend has intersected a new 2.2km high grade feeder structure recently named the Chikamin Feeder Zone, along with potentially two new parallel high grade feeders within the 100% RTR (E69/3787) tenement. The delineation of these zones has led to a further expansion of the Chinook Prospect's mineralised footprint to over 5.5km x 2km. The Chinook Prospect is located within the Earaheedy Project, 110km northeast of Wiluna, Western Australia.

RC Drilling Results - Sweetwater Trend - Chinook Prospect West Extension -E69/3787Chikamin Feeder Zone. High grade Zn-Pb mineralisation has been defined over a strike of 2.2km on 200m by 100m drill sections in association with a northwest-southeast trending structural zone, which is interpreted to be a mineralised feeder fault. The newly named Chikamin Feeder Zone extends into Rumble's 100% owned tenement (E69/3787) and occurs along the previously highlighted Sweetwater Trend.

This new feeder zone is parallel to the earlier discovered Kalitan Feeder Zone, which lies 1.5km to the northeast. Some of the more significant RC results associated with the Chikamin Feeder included: 12m @ 5.49% Zn + Pb from 56m (EHRC596): Inc. 6m @ 9.90% Zn + Pb from 57m; 56m @ 2.00% Zn + Pb from 103m (EHRC598): Inc. 18m @ 3.78% Zn + Pb from 103m Inc. 14m @ 4.25% An + Pb from 107m; 38m @ 2.22% Zn + Pb from 83m (EHRC603): Inc. 3m @ 4.63% Zn + Pb from 85m, and 2m @ 8.01% Zn + Pb from 118m; 9m @ 3.37% Zn + Pb from 63m (EHRC600): Inc. 1m @ 9.28% Zn + Pb from 64m; 28m @ 1.76% Zn + Pb from 70m (EHRC592): Inc. 1m @ 9.11% Zn + Pb from 71m. The sulphide mineralisation is dominated by sphalerite, galena and pyrite and is hosted within the Navajoh Unconformity Unit, which lies above the regionally extensive Navajoh Unconformity.

The mineralisation is broad (up to 50m true width) with high grade core intervals and is shallow dipping. The Chikamin Feeder Zone is open to the northwest and is likely associated with the original Chinook discovery intercepts (EHRC050 - 24m @ 5.57%Zn + Pb and EHRC044 - 21m @ 4.31% Zn + Pb) which lie to the southeast. Further Potential Parallel Feeder Zones: Additional broad parallel intercepts of sulphide Zn-Pb mineralisation with high grade core zones have also been delineated approximately 300m and 600m west of the Chikamin Feeder Zone.

Results include: 22m @ 2.88% Zn + Pb from 62m (EHRC609): Inc. 12m @ 4.1 % Zn + Pb from 69m Inc. 7m @ 5.08% Zn + Pb from 72m; 53m @ 1.13% Zn + Pb from 43m (EHRC632) Inc. 6m @ 4.22% Zn + Pb, 24 g/t Ag from 72m, and 2m @ 8.15% Zn + Pb, 16 g/t Ag from 76mThe high grade mineralisation is sulphide and sphalerite (ZnS) dominant and is also strongly anomalous in Ag. These new zones hosted within the Navajoh Unconformity Unit are likely to further increase the Chinook mineralised footprint which now has a strike length of over 5.5km.RC Drilling Results - Spur Feeder Zone - E69/3464RC drilling results to the east of Chinook at the Spur Feeder Zone has shown strong continuity of high grade mineralisation within broad intervals (60m wide) of Zn-Pb sulphide mineralisation. The Spur Zone is inferredto trend east-west and is contiguous with the Kalitan Feeder Zone.

Mineralisation remains open to the eastand at depth. Latest results include; 64m @ 1.42% Zn + Pb from 80m (EHRC466): Inc. 5m @ 7.62% Zn + Pb from 127m; 24m @ 2.00% Zn + Pb from 86m (EHRC465): Inc. 7m @ 4.39% Zn + Pb from 97m: Inc. 2m @ 7.03% Zn + Pb from 101m. Chinook Potential Mineralisation at the Chinook now has a strike in excess of 5.5km and remains open in all directions.

The Chinook Deposit is a large-scale epigenetic Zn-Pb unconformity related system with mineralization structurally controlled by multiple northwest- southeast and east-west feeder structures/faults. The Kalitan and the newly defined Chikamin Feeder Zones reflect higher grade Zn-Pb mineralisation associated with the northwest-southeast trending structures. Both zones are over 2km long and remain open along strike.

To the southeast of the Chikamin Feeder Zone lies the original discovery holes (EHRC050 - 24m @ 5.57%Zn + Pb and EHRC044 - 21m @ 4.31% Zn + Pb), which are now inferred to be associated with the same structural corridor as Chikamin. East-west mineralisation has been defined at the Spur Zone and several areas within the Chinook mineralised footprint have strong east-west orientations. The latest drilling results have emphasised the strong continuity in grade and widths further to the west along the 15km Sweetwater Trend.

The historic Sweetwater Prospect lies approximately 12km to the west of Chinook deposit within the Sweetwater Trend. This highly prospective corridor will be tested by RC drilling over the coming months, and the Company looks forward to presenting further developments as assay results are returned. Next Steps at the Earaheedy project: RC drilling to target further high grade feeders is ongoing along Sweetwater Trend.

Assays from 38 RC and diamond drill holes from the recent campaign at the Tonka- Navajoh Prospect, which were planned to infill and extend the Colorado and Magazine High Grade Feeder Zones are pending. The Company is currently planning further RC/DDH drilling to test the many potential high grade east-west and northwest-southeast feeder structures that have been recently outlined via lithostructural mapping and interpretation of the geological data compiled to date over the Project. Sighter metallurgical test work to develop a preliminary flowsheet for the sulphide flotation concentrate is progressing well and will be reported as soon as final results are compiled.

An independent technical study to determine the optimum drill spacing for a maiden resource has commenced, with a maiden JORC mineral resource estimate (MRE) due to be reported in 2023. Rumble is investigating beneficiation techniques e.g. DMS & sensor ore sorting to increase the potential resource and enhance the optionality for the Project.
