The results are part of the program drilled in August 2023. Bryah (49%) and OMM (51%) have a Joint Venture (JV) to undertake exploration to test targets in the area, with a view to commencing manganese production. OMM is a wholly owned subsidiary of OM Holdings Limited (ASX: OMH), one of the world’s leading suppliers of manganese ores. Commenting on the drilling, Bryah CEO Ashley Jones said: “These excellent drill results follow our other news flow, being the updated manganese resource and the granting of the mining leases. All the manganese JORC resources are now on granted mining leases. The August drilling results continue to expand the mineralisation at Brumby Creek West and Redrum. Our grades reported are Bryah Resources Limited 191B Carr Place Leederville, WA 6013 Phone: +61 8 9321 0001 Email: info@bryah.com.au ASX: BYH ABN: 59 616 795 245 using cutoffs higher than many other ASX reported resource grades, which should give us the competitive edge when it comes to mining”. The Bryah Basin project area is located approximately 100km north of the town of Meekatharra in Western Australia. The Company’s tenements and manganese mineral rights cover 1,135km² over parts of the western Bryah Basin. Figure 1 shows the Manganese Joint Venture tenement package, with prospects and an existing manganese Mineral Resource. 1 The August 2023 drill program covered 95 holes for 2938 metres. The prospects drilled were Brumby Creek West, Epona, Redrum, Black Hill North and Gold Trip. The best drill intersections continued to come from the extensional drilling around the resources at Brumby Creek and Redrum.

The mineralisation appears to be bifurcating with excellent results on the western side becoming prominent. Grade though is still excellent, with the best results of: • • • 6m at 24.4% Mn from 19m in hole BBRC0249 13m at 22.7% Mn from 15m in hole BBRC0241 4m at 22.05% Mn from 28m in hole BBRC0251 Figure 2 Collar Plan of August 2023 Manganese Drilling at Brumby Creek West (Red collars) ASX: BYH | bryah.com.au 3 Figure 3 Oblique Section Brumby Creek West Prospect Redrum Following the mineralisation to the northeast has continued to give excellent results, whereas results to the south have closed out the mineralisation. The best northern Redrum results are: • • • • • • 7m at 29.3% Mn from 21m in hole RRRC074 8m at 29.6% Mn from 14m in hole RRRC076 5m at 21.0% Mn from 11m in hole RRRC072 7m at 20.7% Mn from 20m in hole RRRC072 3m at 21.2% Mn from 30m in hole RRRC072 4m at 23.8% Mn from 12m in hole RRRC084 The resource at Redrum is 780,000 tonnes - 429Kt at 19.2% Mn Indicated Resource and 251Kt at 18.0% Mn Inferred Resource (Table 1) . These further results extend the mineralisation to the north. Drilling mostly closed out the southern extent.

Channel manganese was not intersected. Two holes intersected surface cap manganese. Figure 6 Collar Plan of August 2023 Manganese Drilling at Black Hill North (Red collars) The surface cap is high grade in places returning: • • 3m at 34.8% Mn from surface in hole BHRC038 2m at 23.0% Mn from 1m in hole BHRC042 ASX: BYH | bryah.com.au 6 Gold Trip The drilling at Gold Trip only intersected surface cap style mineralisation. Bryah will evaluate any other potential in the area. The notable result was: • 2m at 25.5% Mn from 3m in hole GTRC005 Figure 7 Collar Plan of August 2023 Manganese Drilling at Gold Trip (Red collars) Epona The surface mapping at Epona indicated potential manganese over a large area. The area was drilled on an 80m line spacing to test the potential. The most southern lines showed significant intersections and worthy of follow up for a potential channel manganese mineralisation. The southern holes gave intersections of: • 5m at 21.0% Mn from 15m in hole EPRC015 ASX: BYH | bryah.com.au 7 • 3m at 20.4% Mn from 12m in hole EPRC016 Figure 8 Collar Plan of August 2023 Manganese Drilling at Epona (Red collars) The drilling will now be incorporated in to the current JORC resource.

ASX: BYH | bryah.com.au 8 ABOUT BRYAH RESOURCES Bryah’s assets are all located in Western Australia, a Tier One global mining and exploration jurisdiction. Strategically the Projects are energy metals focused, or able to exploit synergies of geological knowledge, locality and exploration. The prospective Bryah Basin licences cover 1,048km2 and have a potential new Volcanogenic Massive Sulphide (VMS) ‘Horseshoe Lights type’ mine analogue at the Windalah prospect, and multiple other similar untested targets. The area also contains extensive outcroppings of manganese, the subject of a substantial $7M joint venture with ASX listed OM Holdings Limited (ASX: OMH). OMH is a vertically integrated manganese producer and refiner with a market capitalisation of over $350m. Bryah and OMH have an excellent working relationship, with OMH having already spent over $3.5 million to earn-in to the Manganese Rights of the Project. Gabanintha, near Meekatharra, has a JORC 2012 Mineral Resource for Cu, Ni, Co 4 and additional structural gold potential. The copper nickel resource and recently identified gold mineralisation at Gabanintha will be the subject of further drill definition and a prefeasibility study to integrate the project with the Australian Vanadium Project (ASX: AVL). The resource has been defined by the drilling efforts of AVL in the development of its vanadium project and enabled Bryah to define a base metal resources inventory. Bryah’s base metals inventory at Gabanintha and manganese JV in the Bryah Basin have a clear pathway to production, which will be significantly advanced in 2023 by the commencement and completion of metallurgical feasibility studies at both projects. The Lake Johnston tenements are prospective for battery metals lithium and nickel. The corridor near Lake Johnston contains significant mines and discoveries of nickel and lithium, including the Mount Holland Lithium Mine and the historical Maggie Hays/Emily Ann nickel deposits. Bryah holds 14.73% of gold focused Star Minerals (ASX:SMS). Star has a Mineral Resource at Tumblegum South and exploration prospects in the West Bryah Basin. 4 See ASX announcement dated 25th May 2022 ‘36.0 MT Ni-Cu-Co Mineral Resource at Gabanintha’.

Exploration Results Section 1 Sampling Techniques and Data Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (e.g., cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. • For this drilling program Bryah Resources Limited (Bryah Resources) utilised vertical Reverse Circulation (RC) drill holes. • RC drilling was to accepted industry standard producing 1m samples of approximately 3kg weight which were collected beneath a cone splitter mounted under the cyclone. • The splitter reject sample was collected into green plastic bags which were numbered and laid into 10m rows, left in place at the hole until assays were returned and results validated. • The holes were sampled as 1m samples from the splitter and placed into pre-numbered calico bags with the draw-sting tied up and then placed inside the green plastic bag for later collection and despatch. • The full length of each hole drilled was sampled, but only selected samples (based on visual logging) were collected and submitted to a contract commercial laboratory for sorting, drying, crushing, splitting, and pulverising. • A prepared sample is then fused in a lithium borate flux with lithium nitrate additive. The resultant glass bead is analysed via X-Ray Fluorescence (XRF). XRF is suitable analysis for a wide range of geological ores. Drilling techniques • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. • Bryah Resources’ RC holes were drilled with a contract slimline RC drilling rig. Drill sample recovery ASX: BYH | bryah.com.au • The RC samples were not weighed or measured for recovery on the rig but will be completed on a campaign basis later as required. A visual estimate of recovery was made in 3 categories (Poor/Fair/Good). • To ensure maximum sample recovery and the representivity of the samples, an experienced Company geologist was present during drilling to monitor the sampling process. Any issues were immediately rectified. • Bryah Resources is satisfied that the RC holes have taken a sufficiently representative sample of the interval and minimal loss of fines has occurred in the RC drilling resulting in minimal sample bias. • No twin RC drill holes have been completed to assess sample bias. 15 Criteria JORC Code explanation Commentary • At this stage, no investigations have been made into whether there is a relationship between sample recovery and grade. Logging • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. • All the 1m RC samples were sieved and collected into 20m chip trays for geological logging of colour, weathering, lithology, alteration and mineralisation for potential Mineral Resource estimation and mining studies. • RC logging is both qualitative and quantitative in nature. • The total length of the RC holes was logged. Where no sample was returned due to cavities/voids it was recorded as such. Sub-sampling techniques and sample preparation • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality, and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. • Sampling technique: o All RC samples were collected by the RC rig into a cyclone and then passed through the cone splitter. o The samples were generally dry, and all attempts were made to ensure the collected samples were dry. Moisture was logged in a qualitative way. o The cyclone and cone splitter were cleaned with compressed air at the end of every 6m RC drill rod. o The sample sizes were appropriate to correctly represent the mineralisation based on the style of mineralisation, the thickness and consistency of intersections, the sampling methodology and percent value assay ranges for the primary elements. • Quality Control Procedures were: o A duplicate sample was collected at regular intervals on the cyclone nominally 1 per 20 samples. o Certified Reference Material (CRM) samples were inserted in the field every 50 samples containing a range of manganese values. o Blank samples are inserted at the start of each hole. o Overall QAQC insertion rate of 1:15 samples o Laboratory repeats taken and standards inserted at pre-determined level specified by the laboratory. o Sample preparation at the laboratory: The samples are weighed and dried at 105oC, then coarsely crushed to -6.3mm using a jaw crusher. If the sample size is greater than 2.5kg the samples are then riffle split. Samples are then pulverised by LM5 or disc pulveriser to 80% passing -75 microns. ASX: BYH | bryah.com.au 16 Criteria JORC Code explanation Commentary o The sample sizes are considered appropriate to correctly represent the mineralisation based on the style of mineralisation, the thickness and consistency of intersections, the sampling methodology and the assay value ranges expected for manganese and its impurities. Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. • The verification of significant intersections by either independent 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. • XRF is suitable for the total analysis of a range of geological ores and is appropriate for analysis of manganese and its associated impurities. • Duplicates, blanks, and Certified Reference Material standards were included in the analyses. Location of data points • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. • All collars have currently been surveyed with a handheld GPS by Bryah staff and will be independently surveyed by surveyors using a differential GPS for accurate collar location and RL. The digital data has been loaded directly to the company SQL Server database. • No downhole surveys have been completed as all holes are shallow and nominally vertical. • The grid system for the Bryah Basin prospect is MGA_GDA94 Zone 50. • Topographic control is from a digital elevation model derived from aerial geophysical surveys. Data spacing and distribution • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. • As this program tested several locations there was considerable variation in the drill spacing and drillhole orientation. • The drill spacing in this program is to provide sufficient information to establish the degree of geological and grade continuity applied under the 2012 JORC code for a mineral resource. Sample compositing was not applied to this drilling; all sampling was at 1m intervals. Verification of sampling and assaying ASX: BYH | bryah.com.au • Significant intersections have been independently verified by alternative company personnel. • The use of twinned holes has not been implemented and is not considered necessary at this stage of exploration. • The Competent Person has visited the site and supervised the drilling and sampling processes in the field. • All primary data related to logging and sampling are captured usin
