Announcement PDF ASX ANNOUNCEMENT 24 January 2025 Manganese update- Ground Penetrating Radar Trial and OMM Farm-in to 60% HIGHLIGHTS  Ground Penetrating Radar (GPR) used for trial delineation of channel type manganese  OMM earns into 60% by spending $1.8 million  Environmental field surveys commencing soon on Mining Licences Bryah Resources Limited (ASX: BYH, “Bryah” or “the Company”) in conjunction with OM (Manganese) Ltd (OMM) is pleased to announce that a trial of Ground Penetrating Radar (GPR) has been completed and assessed. The GPR survey targeted areas of manganese at the Bryah Basin manganese project. The GPR was utilised in areas of known mineralisation to assess its suitability in future exploration. The trial was part of the commitment to find ways to delineate the manganese channel deposits. OMM also has completed a $1.8M earn-in as part of the JV Farm-in agreement and now owns 60% of the project. OMM is a wholly owned subsidiary of OM Holdings Limited (ASX: OMH), one of the world’s leading suppliers of manganese ores. Bryah confirmed that it would not contribute to the JV and that the earn-in would continue from 60% - 70% as per the JV agreement1. Commenting on the trial, Bryah CEO Ashley Jones said: “We are still evaluating more efficient ways to locate manganese channel mineralisation at depth. This trial has opened another possible solution to delineating these Mn channel deposits. Environmental studies on the mining licences has been scheduled for 2025 and will include flora and fauna studies.”. 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 2 shows the Manganese Joint Venture tenement package, with prospects and an existing manganese Mineral Resource of 3.06 MT at 20.1% Mn. 2 See ASX announcement dated 26th August 2019 See ASX announcement dated 24th August 2023 1 2 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 Figure 1: Bryah geologist collecting GPR data ASX: BYH | bryah.com.au 2 Figure 2: Prospect locations with geology map showing the Horseshoe Formation The GPR trial was variable finding the top of the known manganese channel deposit in some trial lines but failed to delineate it in other lines. Due to the lithology immediately above the Mn channel changing, it is likely the cause of the differing results as some conductive overlying lithologies dissipates the signal from the GPR.

ASX: BYH | bryah.com.au 4 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 $4.5 million to earn-in to the Manganese Rights of the Project. Gabanintha, near Meekatharra, has a JORC 2012 Mineral Resource for Cu, Ni, Co 3 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, the historical Maggie Hays/Emily Ann nickel deposits. Bryah holds 9.03% of gold focused Star Minerals (ASX:SMS). Star has a Mineral Resource at Tumblegum South and exploration prospects in the West Bryah Basin. 3 See ASX announcement dated 25th May 2022 ‘36.0 MT Ni-Cu-Co Mineral Resource at Gabanintha’.
