Announcement PDF ASX ANNOUNCEMENT 11 December 2023 Soil sample program underway at Bryah’s Lake Johnston Lithium Projects HIGHLIGHTS   Soil sampling program at Lake Johnston commenced. Lithium soil anomalies found in soil orientation lines at the Pegasus and Arpeggio prospects Bryah Resources Limited (ASX: BYH, “Bryah” or “the Company”) is pleased to announce the start of a soil sampling program at its wholly owned Lake Johnston Project, prospective for lithium and nickel. Commenting on the sampling program, Bryah CEO Ashley Jones said: “With the focus on Lake Johnston Lithium exploration, it is great that we have been able to mobilise a contractor to assist with the collection of soil samples. The crew will initially start following up the anomalies in the Pegasus prospect area, before moving to Arpeggio and Roundbottom prospects near Mt Day. Soil sampling is an easy and effective exploration technique to find LCT pegmatites that are not exposed at surface. The recent discoveries 1 by TG Metals (ASX:TG6) and the Rio Tinto’s exploration transaction with Charger Metals 2 (ASX:CHR) has highlighted the Lake Johnston regions Lithium prospectivity” The Lake Johnston Project consists of eight granted exploration leases and one lease under application covering 794 km2. The exploration ground is within 10 kilometres to the east of the world class Mount Holland Lithium mine. TG metals and Charger Metals have also had Lithium pegmatite discoveries in the area. Tenements are also adjacent to the Mt Day lithium Field, with reported grades over 3% Li2O 3 ASX:TGG 30 October 2023 High Grade Lithium Intercepted at Lake Johnston ASX:CHR 20 November 2023 Rio Tinto and Charger Metals sign Farm-in Agreement 3 WAMEX report A131330 1 2 ASX: BYH | bryah.com.au 1 Figure 1 Location of The Lake Johnston area in Western Australia For further information, please contact: Ashley Jones, CEO +61 8 9321 0001 This announcement has been produced in accordance with the Company's published continuous disclosure policy and has been approved by the Board.

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 ~$300m. 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, Co2 and additional structural gold potential. The copper nickel resource and 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.
