Rumble Resources Limited announced the high-grade assay results of expedited RC hole EHRC370 drilled within the newly discovered major feeder fault zone named the Kalitan Feeder Zone at the Chinook Zn-Pb-Ag-Cu Prospect located on the emerging World Class Earaheedy Base Metal Project in Western Australia. Shallow high-grade sulphide Zn-Pb mineralization with strong silver has been intersected in RC drill-hole EHRC370 within the newly discovered feeder fault zone (Kalitan Feeder Zone) which lies along the northeast margin of the large-scale Chinook Prospect that currently has a 4.1km by 1.9km mineralized footprint and remains open both laterally and at depth. Hole EHRC370 returned: 51m @ 4.76% Zn + Pb, 5.81 g/t Ag from 82m including; 20m @ 8.78% Zn + Pb, 11.65 g/t Ag from 98m, With a higher-grade core of 8m @ 14.61% Zn + Pb, 17.7 g/t Ag from 104m, and 8m @ 5.53% Zn + Pb, 5.08 g/t Ag from 124m.

The mineralisation lies predominantly within the Navajoh Unconformity Unit and comprises of multi-facies siltstones, marls, micrites, sandstones with intercalated sabkha (evaporites) horizons. The Navajoh Unconformity Unit represents multiple regression and transgression stages. The unconformity is a palaeo-karst zone when above the Navajoh Dolomite and transitions into variable mixed multi-facies clastics when above underlying shales and siltstones.

The upper contact of the Navajoh Unconformity Unit with the overlying Frere Iron Formation is interpreted as another unconformity. See image 5 for the interpreted geological model and mineralisation styles. The mineralisation is interpreted to be flat to shallow northeast dipping and represents a lateral sphalerite-galena-pyrite "migration" zone, which has pervaded both laterally and preferentially through more porous sediments close to and away from multiple sub-vertical extensional fault zone corridors.

The fault zone corridors are considered feeders with respect to extensive epigenetic metal enriched fluid flow. Copper with minor cobalt develops within the feeder faults and laterally close to the feeders where the deposition temperature is likely higher. Sphalerite is the dominant sulphide species with the overall Zn:Pb ratio around 3 to 1. Silver has a strong ssociation with galena.

Overall, six drill-holes are interpreted to intersect within or close to the Kalitan Feeder Zone over a strike length of 2.3 km. The current northwesternmost drill-hole is inferred to intersect part of the Kalitan Feeder Zone. The overall intersection for TDH14 is 10m @ 3.5% Zn + Pb with a higher-grade core zone of 4.5m @ 5.43% Zn + Pb from 225m.

Earlier drill-holes completed by Rumble toward the southeast of the Kalitan Feeder Zone highlight the cross-cutting nature of the Kalitan Feeder Zone with the lithological strike. The Kalitan Feeder Zone mineralisation has a shallow northwest plunge and the up-dip position of the zone daylights further southeast under shallow cover. All three drill-holes returned wide low-grade mineralisation with higher-grade core zones, strong Ag and elevated Cu and Co.

The Kalitan Feeder Zone longitudinal section highlights drill-holes with both current assay results and pending assays along with a broad >0.5% Zn + Pb mineralization halo which has been inferred from wet assays and pXRF analyses from the pending holes. Rumble routinely completes XRF analysis on every metre drilled. Since the Chinook discovery in April 2021, scoping drilling has uncovered a rapidly expanding world class scale Zn-Pb-Ag-Cu base metal system, with the drilling continuing to make discoveries and new multiple large-scale targets emerging.

The overall geological deposition model for the Earaheedy Base Metal Province is continually evolving with some five styles of mineralisation identified. Rumble has confirmed at least four of these styles within the Earaheedy Project area, and based on recent drilling completed by Strickland Metals, the likelihood of significant Iroquois Dolomite hosted mineralisation below Chinook, Tonka, Magazine and Navajoh is high. The current drilling has outlined laterally extensive flat lying unconformity related zinc-lead-silver dominant sulphide mineralisation at the Chinook, Tonka, Magazine and Navajoh Prospects.

The mineralization footprint at Chinook is 4.1km by 1.9km and is completely open and the mineralization footprint of the Tonka, Magazine and Navajoh Trend is 6km by 1.2km and completely open. To the southwest and immediately below the unconformity related mineralization at Tonka, a very wide low-grade Zn-Pb zone has been discovered within the Purple Shale unit that lies below the Navajoh Unconformity. The mineralization is a wide fracture zone with multiple fault/sulphide veinlets with Zn-Pb-Ag-Cu-pyrite.

Historic drilling completed by RGC (Renison Gold) within the main Navajoh Dolomite unit which lies down-dip and to the northeast of the current Rumble prospects, intersected MVT Zn-Pb-Ag fault related mineralisation. 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. 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 is based on the current geological understanding of the mineralization 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 approximately 50% of some 50,000m of drilling completed by Rumble.
