Juno Project – Electrical Geophysics Commencement

Juno Project - Commencement of Electrical Geophysics

Key Highlights

- Electrical Geophysical programmes commence at Juno Project comprising Induced Polarisation (IP) and Electromagnetics (EM)

- IP and EM to detect electrical responses from subsurface bodies at depth

- Results to be integrated with existing subsurface models to generate locations for the Company's first drill holes for Juno Project

GEO Exploration Limited (LSE AIM: GEO) is pleased to announce that its wholly owned subsidiary Juno Gold Pty Ltd (Juno Gold) has commenced ground based Electrical Geophysical programmes at the Juno Project. The Juno Project is located in central Western Australia where the company is conducting exploration for large Intrusion Related Gold Systems (IRGS) which host precious and base metal mineralisation.

The Electrical Geophysical programmes comprise Induced Polarisation (IP) and Electromagnetics (EM) and will be carried out over the northern parts of the project area.

Dipole Dipole IP will be carried out to detect subsurface electrically chargeable and electrically resistive bodies at depth. IRGS type mineralisation can demonstrate a chargeable or resistive response relative to host rock and IP can be used as a direct detection method enabling more robust drill targeting.

The Company will also complete a programme of moving loop EM at the Juno project. EM will commence following completion of IP. The EM method allows detection of electrically conductive bodies at depth and provides for spatial modelling of the location of those bodies. Comparison of IP and EM models allows characterisation of the potential mineralisation type, for example disseminated sulphide mineralisation versus massive sulphide mineralisation.

Several lines of Dipole Dipole IP and moving loop EM will be collected and the data will be modelled with modern geophysical software. Data collection and modelling is expected to be complete in the coming weeks. Modelled IP and EM data will be integrated with existing magnetic and gravity models as previously announced on 28 May 2025. Final models will provide locations for GEO's maiden drill holes at Juno Project.

Callum Baxter, GEO's joint venture partner commented:

"We are moving quickly at Juno and it is exciting to have commenced Electrical Geophysics. The IP and EM work will enhance our subsurface information based on existing magnetic and gravity models at the project. Results of this work will rapidly culminate in the generation of locations for our first drill holes at Juno for our maiden drill programme."
