Announcement PDF ASX ANNOUNCEMENT 2 AUGUST 2023 Manganese Drilling Commences HIGHLIGHTS  Drilling commences on new prospects  2500 metres planned of Reverse Circulation (RC) drilling  Resource modelling underway to update the Manganese JORC Resource Bryah Resources Limited (ASX: BYH, “Bryah” or “the Company”) in conjunction with OM (Manganese) Ltd (OMM) is pleased to announce the start or drilling at the Bryah Basin manganese project. 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 RC drilling, Bryah CEO Ashley Jones said: “It is great to be drilling on our Manganese project again following heritage and government approvals. We have identified many new manganese prospects to be drill tested and look forward to continuing our success of finding further mineralisation. Our strategy remains the same; getting to a critical mass to enable restarting of operations. Further exploration success will complement the mining licence applications and resource updates currently underway. ” Drill Targets Mapping, rock chip results and GAIP (Ground Array Induced Polarisation) surveys have identified drill prospects to be tested. As previously announced mapping and rock chip results1 included: 1 • Black Hill Northeast prospect include: 54.9% Mn, 50.3% Mn, 49.5% Mn, 53.3% Mn • Gold Trip prospect include: 47.5% Mn, 45.7% Mn, 38.2% Mn, 35.5% Mn • Epona prospect include: 41.5% Mn, 38.1% Mn, 36.3% Mn, 33.3% Mn, • Black Beauty North prospect include: 42.4% Mn, 40.0% Mn, 39.2% Mn, 35.7% Mn See ASX announcement dated 2nd February 2023 ‘ High-grade Rock Chips confirms Manganese Prospectivity’.

Both applications are on the exploration tenement E52 /3237. The application numbers are M 52/1087 for the Brumby Creek area and M 52/1088 for the Black Hill area. 2 See ASX announcement dated 10th July Manganese Mining Licence Applications Submitted ASX: BYH | bryah.com.au 2 FUTURE WORK An updated resource estimate bringing together the drilling in 2022 is underway and is expected by the end of August. An environmental consultant has been engaged to take the Mining Licence application areas through the approvals process.

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 $400m. Bryah and OMH have an excellent working relationship, with OMH having already spent over $3 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. An option agreement has been signed over the Lake Johnston tenements which are prospective for battery metals lithium and nickel. On IPO the option holder Mining Green Metals Ltd will pay 5 million shares for 70% of the project, with another 5 million shares for the remaining 30%. 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 20.75% 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’.
