Rumble Resources Limited announced significant new high- grade Zn-Pb drilling results and the definition of multiple new mineralised zones (potential feeder structures) at the Chinook and Tonka Prospects from ongoing exploration activities at the Earaheedy Project, 140km northeast of Wiluna, Western Australia. The Tonka Prospect is significantly advancing in size and grade with some of the widest and highest-grade, zin dominant, drill intercepts recorded to date on the Earaheedy Project. Drilling during the period has led to linking the Tonka and Navajoh Prospects, thus defining over 8kms of mineralisation which remains open along strike an down-dip.

The geological and assay information from the drilling has also identified a series of east-west structure controlling the higher-grade mineralisation, which are inferred to be feeder structures coincident with gravity gradie features. These high-grade zinc dominant structures are up to 5km in strike and remain open. Infill drilling within the Chinook Prospect on the northwest trending Kalitan Feeder Zone has also highlighted a ne high-grade Zn-Pb east- west structure which is open along strike and at depth.

This new zone add a new dimension to Chinook, highlighting a possible network of east west feeder zones similar to that inferred Tonka-Navajoh, within the 5km long northwest trending mineralised footprint. The first infill stage (200m by 100m drill pattern) at the Tonka Prospect has successfully intersected wide zones of high-grade zinc dominant mineralisation. Geological and geophysical interpretation based on the infill drilling has highlighted a strong association with a series of underlying east-west mineralised structures coincident with gravity features throughout the Tonka - Navajoh Prospect trend.

The multiple mineralised structures are interpreted to be high grade feeder faults that transgress the Navajoh Unconformity Unit into the underlying lithologies that strike northwest and dip very shallowly to the northeast. The latest interpretation has significantly advanced the litho-structural understanding at Tonka - Navajoh trend and will greatly enhance future drill targeting. The mineralisation is sphalerite dominant and primarily hosted at the base of the Navajoh Unconformity Unit and into an underlying silicified dolomite.

Both disseminated and massive pyrite is associated with lesser galena and dominant sphalerite throughout the broad width of mineralisation. The sphalerite is typically coarse grained and is low in iron. Table 2 highlights the individual metre assay results for EHRC515 and EHRC518.

The newly interpreted Magazine Zone is another significant sub-parallel east-west structure which lies 500m south of the Colorado Zone and is interpreted to link the Tonka and Navajoh Prospects over an open strike of 5km. A further two higher-grade mineralised zones lie 800m and 1500m south of the Magazine Zone and may represent potential mineralised feeder structures. Photos 1 and 2 of drill core come from the same diamond hole EHD027 which is a twin of the RC hole EHRC518 that intercepted 7m @ 10.71% Zn + Pb (8.52% Zn, 2.19% Pb) including 3m @ 19.93% Zn + Pb (15.88% Zn, 4.05% Pb).

EHD027 is still being cut and orientated and will be sent to the lab for assay in due course. The brecciation in photo 1 is interpreted to support a mineralised high-grade "feeder", whilst the zinc dominant mineralisation displayed in photo 2 reinforces the stratiform nature of the broad mineralisation and potential for large- scale development. The brecciation is interpreted to occur over a broad area as it is seen within the RC twin and adjacent hole EHRC515 100m away (normal to the inferred strike of mineralisation).

The mineralised setting is interpreted to be different to the Chinook deposit as there is very little if any NUU deposited above the unconformity with the massive sphalerite predominantly hosted in silicified dolomite. The brecciated zinc core in photo 1 is structural i.e. a fault has cut the silicified dolomite and mineralisation pervades (hydraulic breccia) the open spaces. The layer parallel bands of zinc in photo 2 occur within an extensive silicified stromatolitic dolomite unit mineral algae mats) and are interpreted to be replacing the more porous layers within this formation.

Results for eighty-four drill-holes completed at Chinook were received. The drilling density has moved from scoping to a 400m/200m by 100m infill pattern, with the primary focus on the recently discovered high-grade Kalitan Feeder Zone. Ongoing geological interpretation from the infill drilling of the Kalitan Feeder Zone has highlighted the structural complexity associated with multiple faulting stages thought to be associated with post mineralisation reactivation along the Lockeridge Fault System, which has block faulted the higher-grade Zn-Pb zones at Chinook.

Although the faulting has moved the Kalitan Feeder relatively short distances normal to strike, the zone has demonstrated strong continuity. The infill drilling has also defined a new zone with higher-grade Zn-Pb mineralisation that intersects the Kalitan feeder zone and is termed the Spur Zone. The Spur Zone trends east west and is open to the east and at depth.

To the southeast, an isolated drill-hole (EHRC437-image 2) returned a narrow higher-grade intersection of 1m @ 8.4% Zn + Pb from 117m, below a zone of low-grade oxide mineralisation. This mineralisation is open and the outcome is significant as it may suggest the mineralised Navajoh Unconformity Unit has been uplifted. Since the exciting Chinook discovery in April 2021, drilling has rapidly uncovered an emerging world class Zn-Pb- Ag-Cu metal system with provincial scale potential.

Within tenement E69/3464 the Zn-Pb-Ag mineralisation occurs within a 19km by 2km corridor which is open in all directions and at depth. Higher-grade zones within the broadly mineralised Navajoh Unconformity Unit and underlying dolomite (Sweetwaters Well Dolomite - formerly Navajoh Dolomite) are associated with multiple inferred feeder faults/zones that are oriented northwest and east- west.
