Zug, Switzerland: February 17, 2025 – As an update to previous project-related communications on the 12 December 2024, SunMirror AG (the "Company", "SunMirror", and together with its direct and indirect subsidiaries the "Group", Vienna Stock Exchange: ROR1; ISIN CH0396131929), is pleased to provide further news on its exploration activities in Western Australia.

Highlights:

• At the end of December 2024 MAGSPEC Airborne Surveys PTY Ltd, a company specialising in high resolution, ultra-detailed and regional airborne geophysical surveys completed their aeromagnetic and radiometric survey over 2 discrete areas within the Kingston Keith licence with known historical gold workings.
• Southern Geoscience Consultants (SGC) were subsequently re-engaged to process the new airborne data from these two areas and provide an updated structural report focused on identifying additional potentially gold-bearing structures extending beneath the surface cover from these old gold workings. The new data infilled the previous survey lines to increase the line spacing to 25m. This new data allowed for a much finer resolution of structures within the two areas.
• A total of 44 target areas have now been identified within the Kingston Keith Project Area. The target areas have been prioritised from 1 (high) to 3 (low). A full summary is shown in Appendix 1.
• From the original set of 23 targets identified in the 2023 MAGSPEC survey (i.e., before the 2025 infill magnetics were flown), 13 have been revised using the new data while another 21 new targets have been added, see Figures 1, 2 and 3. The priority 1 targets are focused around historic workings, with mapped geochemical anomalies.

The Company is pleased to announce that MAGSPEC Airborne Surveys Pty Ltd have completed an infill aeromagnetic and radiometric survey over 2 historic gold-bearing areas within its Kingston Keith Licence. The first area covers the historic Enterprise and Kingston gold workings in the NW corner of the licence, and the second covers an area of structures associated with the Mt Keith gold mining central part of the licence.

The survey covered approximately 896-line kilometers, and the data collected was subsequently processed and interpreted by Southern Geoscience Consultants (SGC), a specialist group of geoscientists focused on providing the highest quality integrated geophysical solutions to the resource industry. SGC were instructed to integrate the new airborne data with previous data collected from an earlier (50m flight line spacing) MAGSPEC survey (flown in January 2023) that was commissioned by the Company, and which covered the whole of the Kingston Keith licence area. The new infill survey was flown in between the previous 50m flight lines to try and identify narrower high-grade gold-bearing structures that may have been missed during the much wider 50m line spacing survey.

The next stage for our Kingston Keith licence will be to prioritise and define discrete drill targets areas for a heritage site visit and fauna study. Following that, the Company will apply for a Programme of Work for 5,000m of reverse circulation drilling, supported by an Environmental Exploration Management Plan.

Kingston Keith:

The Kingston-Keith Project falls within the Wiluna region which has been the focus of gold exploration since the late 1800's. Today it is host to multiple major nickel and gold deposits including the Wiluna and Agnew gold deposits, which have produced 8 million ounces (8 Moz) of gold and 3.8 million ounces respectively. The Kingston Keith licence is an under-explored, highly prospective area with significant potential for the discovery of economic gold deposits. Past exploration has seen drill holes return interesting gold grades over significant widths, however much more exploratory drilling is required to determine the continuity of mineralisation and to define mineral resources. Most of the drilling to date within the Kingston-Keith Project has not tested the down-dip and down-plunge potential of the defined anomalies. In addition, most of the tenement has not been drill-tested to depth.

The Kingston Prospect is defined by an extensive set of historical shallow mine workings which date back to the late 19th to early 20th century when the Yilgarn region was subject to extensive prospecting and artisanal mining. The prospect is in the NW part of the licence and covers both the Kingston and Enterprise workings. Significant historic drill intersections are shown below in figure 4.

Laurent Quelin, Chairman and CFO of SunMirror AG, comments: "I am delighted that the recent infill survey flown by MAGSPEC has identified additional structural targets for potential gold and lithium mineralization within our licence. These targets were based on a set of key criteria including one or more of the interpreted presences of key lithologies, structures, historical mineral occurrences and / or sites of alteration. The next stage will focus on the Priority 1 drill targets and cover them with both a heritage site visit and fauna study. Following that, the Company will apply for a Programme of Work (supported by an Environmental Exploration Management Plan) for an initial 3,000 - 5,000m of reverse circulation drilling.

About SunMirror AG

The Group invests into strategic mineral exploration assets with a strong focus on sustainable green battery metals, such as cobalt, lithium and nickel, as well as copper and gold deposits in developed markets. The company aims to either produce minerals at a later stage or sell those assets to strategic buyers. SunMirror's key exploration assets acquired in 2020, are currently located in Western Australia but the Group aims to complement its portfolio with additional early stage mining licenses, focused on Europe with the ultimate aim of providing a secure, stable and sustainable supply of battery raw materials to support the electric revolution. SunMirror's core belief is that exploring for green battery metals must be accompanied by a sustainable approach to mining, thereby aiming to become a reference in terms of "responsible exploration".

The company's shares (ISIN CH0396131929) are listed on the Vienna Stock Exchange (auction trading, ticker: ROR1). For further information, please visit: www.sunmirror.com.
