Project

Carlindie Project: Lithium and Gold

Ownership: Several applications still pending grant

Size: ~1,135km²

Location: 90 kilometres southeast of Port Hedland, Western Australian along the strike of Wildcat Resources Bolt Cutter Lithium Project and neighbouring SQM and Kali Metals Pilbara Lithium Project.

Background: Terrain is seeking to fast track granting of this tenement with several granted.

• Terrain has completed 400m x 400m soil sampling program over 15km long tectonic structure, (see ASX: 01/10/2025).
• Desktop studies have identified key areas fitting to Terrain’s internal geological modelling.
• Terrain’s Carlindie Project is under 3m of soil cover and in a favourable geological setting within WA’s premier Lithium district.
• A Machine Learning study is currently being run over the project area.

Diagram 1: Terrain Minerals Carlindie Project is located within the Pilbara region of Western Australia. The region is arguably Australia’s premier address for lithium mineralisation and hosts significant deposits including Pilbara Minerals’ Pilgangoora lithium operation and Mineral Resources’ Wodgina lithium mine as well as Northern Star’s Hemi gold deposit. The Company’s Carlindie Project is positioned along an interpreted extension of the tectonic structure that hosts Wildcat Resources’ Tabba Tabba lithium deposit and the recently discovered Bolt Cutter Central lithium mineralisation.

Diagram 2: Processing of the open-file Western Australian Government aeromagnetic data highlighted that the tectonic structure associated with Wildcat Resources’ Tabba Tabbe lithium deposit extends into Terrain Minerals Carlindie Project. This results in Terrain Minerals identifying more than 15 kilometres of prospective geology within its 100% owned tenement E45/6524. The prospectivity of this tectonic structure was strengthened following Wildcat Resources ASX announcement dated 4 August 2025, where they reported multiple lithium-bearing pegmatite swarms at Bolt Cutter Central, being the western extension of the same tectonic structure hosted within Terrain Minerals Carlindie Project (see ASX: 01/10/2025).

Diagram 3: Plan of the soil sampling program designed to cover the 15-kilometre strike of the prospective tectonic structure within Terrain Minerals Carlindie tenement E 45/6524. The completed surface geochemical sampling program comprises ~822 individual samples spaced on a 400 x 400 metre grid (see ASX: 01/10/2025).
