New Zinc-Lead-Silver Discovery at Earaheedy Project

Tonka Zn-Pb-Ag Sulphide Discovery

• A new significant zone of flat lying Zn-Pb-Ag sulphide mineralisation has been discovered only 8km's southeast of the Chinook Discovery and 1.3km's northwest of the Magazine Prospect
• The Tonka discovery has an initial footprint of 1.7km strike and 1km down dip length and remains open in all directions, providing potential to significantly increase its dimensions (cf. Chinook)
• The Tonka Zn-Pb-Ag sulphide discovery has similar geological characteristics to the Chinook Zn-Pb-Ag sulphide discovery which is hosted within an extensive and flat dipping sedimentary sequence within a regionally significant unconformity. For comparison, Chinook has a footprint of 4.1km strike and 1.9km down dip length – remains open in all directions
• The Zn-Pb-Ag mineralisation at Tonka is defined on three broad lines 500m and 750m apart – first round of assays returned:
  • o 22m @ 4.27% Zn+Pb, 5.4g/t Ag from 110m (EHRC399) ⃰
    • including 11m @ 5.82% Zn+Pb, 4.35g/t Ag from 121m
  • o 10m @ 3.93% Zn+Pb, 4.34g/t Ag from 84m (EHRC262) ⃰
  • o 5m @ 5.03% Zn+Pb, 9.74g/t Ag from 101m (EHRC263) ⃰
  • o 5m @ 4.47% Zn+Pb, 13.00g/t Ag from 66m (EHRC260) ⃰
  • o 9m @ 3.38% Zn+Pb, 1.29g/t Ag from 88m (EHRC261) ⃰
  • o 8m @ 3.13% Zn+Pb, 2.94g/t Ag from 130m (EHRC265) ⃰

⃰Intersections are true width

• Significantly, wide zones of lower grade Zn-Pb mineralisation have been intersected in a fractured and faulted purple shale zone below the unconformity unit mineralisation (i.e. below the mineralised zones that host Chinook and Tonka) at the southwestern end of Tonka. Results include:
  • o 102m @ 0.5% Zn+Pb from 77m (EHRC257) ¹
  • o 121m @ 0.54% Zn+Pb from 8m (EHRC292) ¹

¹ Mineralised Section >1000ppm Zn + Pb - Down hole length intersection

• These results provide further evidence of the potential for large-scale deposits in the Purple Shale and Iroquois Carbonate Units below the unconformity, which remains untested at Earaheedy (see image 4).
• The 2021 drilling program has once again been expanded to over 50,000m, including further scoping for the new Tonka discovery zone.

Rumble Resources Limited (ASX: RTR) ("Rumble" or "the Company") is pleased to report that the ongoing scoping drill program at the Earaheedy Project has led to a new Zn-Pb-Ag discovery named Tonka, located only 8km's southeast of the Chinook Discovery.

Rumble Resources Managing Director, Mr Shane Sikora said "As predicted, our expanding broad spaced regional scoping drilling is uncovering further mineralisation and potential new large-scale Zn-Pb deposits within this very fertile district. Like the Chinook Discovery, the exciting new Tonka Discovery has the potential to significantly increase in size from its current 1.7km x 1km footprint, due to its open shallow flat lying orientation, association with a regionally extensive unconformity and is open in all directions.

"To date Rumble's drilling has intersected and targeted Zn-Pb mineralisation in the shallow unconformity unit. The new developments of intersecting broad (up to 100m) zones of structurally controlled low grade Zn-Pb-Ag mineralisation in the purple shale unit below the unconformity and the recent reporting of high-grade Zn-Pb mineralisation in the underlying Iroquois Carbonate Member by Strickland Metals (see ASX announcement 14/10/2021], has highlighted the potential for large scale high-grade Zn-Pb deposits below in the lower formations, yet to be drill tested by Rumble – see Image 4 for target areas (specifically zones 4 & 5).

"The ongoing regional scoping drilling success has emphasized the potential for more discoveries in multiple host units throughout the 45km's of strike, highlighting we have only started to scratch the surface of unlocking the world class potential of the Earaheedy Project. We look forward to announcing further assay results from the drilling program as they are received over the coming weeks."

New Tonka Zn-Pb-Ag Sulphide Discovery – E69/3464

The latest drill scoping of the highly prospective unconformity style mineralisation southeast of Chinook has resulted in an exciting new Zn-Pb-Ag discovery at the recently named "Tonka" Prospect.

As a result of this discovery, the 2021 drilling program has now been expanded to over 50,000m to help define the limits of this new Zn-Pb-Ag zone at Tonka.

Image 1. Earaheedy Project – Geology and Location of Prospects

The new Tonka Zn-Pb-Ag discovery is located 8km's southeast of the Chinook Zn-Pb-Ag sulphide discovery and 1.3km's northwest from the Magazine Prospect – see image 1. The mineralised footprint is 1.7km (strike) by 1km (dip length) and is open in all directions.

Assay results have been received and compiled for the first seventeen (17) drill-holes from three drill lines and a short cross line. Results include:

• o 22m @ 4.27% Zn+Pb, 5.40 g/t Ag from 110m (EHRC399)⃰
  • inc 11m @ 5.82% Zn+Pb, 4.35 g/t Ag from 121m
• o 5m @ 4.47% Zn+Pb, 13.00 g/t Ag from 66m (EHRC260)⃰
• o 9m @ 3.38% Zn+Pb, 1.29 g/t Ag from 88m (EHRC261)⃰
• o 10m @ 3.93% Zn+Pb, 4.34 g/t Ag from 84m (EHRC262)⃰
• o 5m @ 5.03% Zn+Pb, 9.74 g/t Ag from 101m (EHRC263)⃰
• o 8m @ 3.13% Zn+Pb, 2.94 g/t Ag from 130m (EHRC265)⃰

⃰Intersections are True Width

At Tonka, an intercept of 22m @ 4.27% Zn+Pb, 5.40g/t Ag from 110m was reported in hole EHRC399 which lies 500m to the southeast and along strike from main drill traverse - Section AC, whilst drilling 1200m to the northwest of the main section AC intersected 16m @ 1.38% Zn+Pb, 6.39 g/t Ag from 49m in EHRC183 (see image 2 for locations).

As at Chinook, the sphalerite-galena-pyrite mineralisation at Tonka occurs within a major regional unconformity that is flat northeast dipping and is hosted within a clastic sedimentary unit made up of siltstones and shales, sandstone and marl (termed the Navajoh Unconformity Unit or NUU) which is overlain by the Frere Iron Formation.

In addition, a large fault system trending north-south has been interpreted to occur along the southwest portion of Tonka. Here, broad and significant low-grade Zn – Pb mineralisation has been intersected and is associated with extensive fracturing of a purple siltstone and shale unit that underlies the NUU. The fault system is interpreted to be east side down which indicates the NUU has been eroded to the west with the lower purple shale/siltstone positioned closer to the surface under shallow lake sediments. Recent results include:

• 102m @ 0.5% Zn+Pb from 77m (EHRC257)°
• 121m @ 0.54% Zn+Pb from 8m (EHRC292)°

° Mineralised Section (>1000ppm Zn + Pb) – Down-hole Length Intersection

Image 3 – Tonka Prospect – AC Section – Geology and Significant Drill Hole Results

The new style of Zn-Pb mineralization with elevated copper is associated with wide zones of small pervasive sulphidic (in primary zone) veinlets within the purple (oxidized) siltstone/shale. The fracturing is multi-directional with the overall trend north-south. Chlorite alteration (potential Zn chlorite – baileychlore) and local ferruginised zones is prevalent throughout the fractured and faulted purple shale/siltstone.

The large fracture zone of Zn-Pb mineralization hosted in the Purple Shale/Siltstone represents a very significant target with the potential for large-scale structural positions both in the purple shale/siltstone and at depth in the lower Iroquois Carbonate Member (especially towards the base).

About the Earaheedy Project

The Earaheedy Project is located approximately 110km northeast of Wiluna, Western Australia. Rumble owns 75% of E69/3464 and Zenith Minerals Ltd (ASX: ZNC) owns 25%. Rumble has applied (100%) for two contiguous exploration licenses ELA69/3787 and ELA69/3862, south and west of E69/3464. The entire project area covers the inferred unconformity contact between the overlying Frere Iron Formation and underlying Yelma Formation of the Palaeoproterozoic Earaheedy Basin.On April 2021 Rumble announced a major Zinc-Lead Discovery with 'Tier 1' deposit potential at the Earaheedy Project (see ASX Announcement 19 April 2021) and followed this up by announcing a Large Sedex Style System Emerging at the Earaheedy Project (see ASX announcement 25 May 2021) on E69/3464. There are now four main prospects within E69/3464, Chinook, Tonka, Magazine and Navajoh which lie along a 17km corridor which is open into the adjacent exploration license application (ELA69/3862). Within the project area, Rumble controls 45km of prospective mineralised strike which has the potential for multiple large tonnage Zn–Pb deposits - See image 5.

First Stage Exploration Target

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.

Earaheedy Zn-Pb Project –Exploration Target
Range	Tonnes	Grade
Lower	100,000,000	3.5% Zn + Pb Sulphide
Upper	120,000,000	4.5% Zn + Pb Sulphide

Table 1: Near surface exploration target down to 120 metre - shallow depth

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 mineralisation 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 from some 50,000m of drilling completed by Rumble. Historic drilling includes sixty-four (64) holes completed within the project area (E69/3464) by previous explorers (refer historical exploration results in previous ASX announcements dated 5 February 2019 and 12 October 2017, 23rd January 2020 which continue to apply and have not materially changed). Some of the considerations in respect of the estimation of the exploration target include:

• Drilling results have demonstrated strong continuity of shallow, flat lying sulphide mineralisation;
• Over 45km's of prospective strike and open (refer image 5);
• Minimum 600m of width based on shallow 7.5° and shallow depth to 120m, based on drilling results;
• True width (thickness) of mineralisation up to 34 metres received in drilling results; and
• Specific gravity (SG) of 2.5 (world average SG of sandstone not accounting for metal).

The Company intends to test the exploration target with drilling and this further drilling is expected to extend over approximately 12 months. Grade ranges have been either estimated or assigned from lower and upper grades of mineralisation received in drilling results. A classification is not applicable for an exploration target.

Section 1 Sampling Techniques and Data

Criteria	JORC Code explanation	Commentary
Samplingtechniques	•Nature and quality of sampling (e.g. cut channels,random chips, or specific specialised industry standardmeasurement tools appropriate to the minerals underinvestigation, such as down hole gamma sondes, orhandheld XRF instruments, etc.). These examplesshould not be taken as limiting the broad meaning ofsampling.•Include reference to measures taken to ensure samplerepresentivity and the appropriate calibration of anymeasurement tools or systems used.•Aspects of the determination of mineralisation that areMaterial to the Public Report.•In cases where 'industry standard' work has been donethis would be relatively simple (e.g. 'reverse circulationdrilling was used to obtain 1 m samples from which 3kg was pulverised to produce a 30 g charge for fireassay'). In other cases more explanation may berequired, such as where there is coarse gold that hasinherent sampling problems. Unusual commodities ormineralisation types (e.g. submarine nodules) maywarrant disclosure of detailed information.	•RC sampling completed on 1mintervals using Metzke Static conesplitter is dry. If wet, sample collectedin large polywoven, then allowed todry for 24 hrs. Sampling was byspear along inside of bag.•Weight of sample was on average>2kg.Samples sent to ALS, Malaga, Perth,•WA and are being assayed using afour acid digest and read by ICP-AESanalytical instrument. At total of 33elements are reported including Ag,Al, As, Ba, Bi, Ca, Cd, Ce, Co, Cr,Cu, Fe, K, La, Li, Mg, Mn, Mo, Na, Ni,P, Pb, S, Sb, Sc, Sr, Th, Ti, Tl, U, V,W, Zn.

The Vanta usedstandards (CRM).•If the assay response was>1000ppm Zn, a sample (>2kg)was taken and delivered to ALSfor wet analysis.•Sampling QA/QC involved aduplicate taken every 20m, and astandard taken every 20m. 4standards (OREAS CRMs) levelsand one blank were usedrandomly.

Criteria	JORC Code explanation	Commentary
Qualityofassaydataandlaboratorytests	•The nature, quality and appropriateness of theassaying and laboratory procedures used and whetherthe technique is considered partial or total.•For geophysical tools, spectrometers, handheld XRFinstruments, etc., the parameters used in determiningthe analysis including instrument make and model,reading times, calibrations factors applied and theirderivation, etc.•Nature of quality control procedures adopted (e.g.standards, blanks, duplicates, external laboratorychecks) and whether acceptable levels of accuracy (i.e.lack of bias) and precision have been established.	•The assigned assaying methodology(4 acid) is total digest.•Asdiscussed,theVantapXRFanalyser was used to threshold thecollection of samples for wet analysis.•InadditiontoRumblesQA/QCmethods (duplicates, standards andblanks), the laboratory has additionalchecks.
Verificationof samplingandassaying	•The verification of significant intersections by eitherindependent or alternative company personnel.•The use of twinned holes.•Documentation of primary data, data entry procedures,data verification, data storage (physical and electronic)protocols.•Discuss any adjustment to assay data.	•Significant intersections reported bycompany personnel only.•Documentation and review is ongoing.Prior to final vetting, entered intodatabase.
Locationofdata points	•Accuracy and quality of surveys used to locate drillholes (collar and down-hole surveys), trenches, mineworkings and other locations used in Mineral Resourceestimation.•Specification of the grid system used.•Quality and adequacy of topographic control.	•All drillhole collars surveyed usinghandheld GPS – Datum is MGA94Zone 51.
Dataspacing anddistribution	•Data spacing for reporting of Exploration Results.•Whether the data spacing and distribution is sufficientto establish the degree of geological and gradecontinuity appropriate for the Mineral Resource andOre Reserve estimation procedure(s) andclassifications applied.•Whether sample compositing has been applied.	•No resource work completed. TheRC drilling is reconnaissance(scoping) by nature with drill holespacing on average 500m x 100mapart.•Single metre and composites used.
Orientationofdatainrelationtogeologicalstructure	•Whether the orientation of sampling achieves unbiasedsampling of possible structures and the extent to whichthis is known, considering the deposit type.•If the relationship between the drilling orientation andthe orientation of key mineralised structures isconsidered to have introduced a sampling bias, thisshould be assessed and reported if material.	•Previous drilling (and historic) hasdefined a consistent flat lyingsedimentary package.•Drilling is normal (90°) to themineralised intersections. True widthreported. No bias.•A single traverse of angled RC holescompleted to ascertain if footwallstructures could be determined. Thesingle traverse was at -60 andrepresented approximately 85% oftrue width.
Samplesecurity	•The measures taken to ensure sample security.	All sampling packaging and security•completed by Rumble personnel,from collection of sample to deliveryat laboratory.
