About Kingston Keith Exploration Licence E 53/1953:
The Kingston-Keith Licence 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 licence 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.

Laurent Quelin, Chairman and CFO of SunMirror AG, comments: "I am pleased to update you on the progress of our Kingston Keith Exploration Licence. As part of our ongoing commitment to unlocking value within our portfolio, we have recently secured an extension of the licence for another 5 years which allows us additional time and access to conduct further exploration work.

This extension was approved following successful compliance with all regulatory and environmental requirements, reflecting the support of the relevant authorities and our commitment to responsible exploration.

Moving forward, we are planning a targeted drilling campaign to delineate and evaluate gold mineralization. The key highlights include:

• Objectives: Confirming the presence of potentially viable gold deposits and gathering geological data to inform future development.
• Locations: Drilling will focus on high priority targets identified through recent geophysical and geochemical surveys.
• Timeline: Drilling is scheduled to commence Q4 this year but is contingent on successful fund raising and execution of an Exploration Agreement with TMPAC.
• Impact: Positive drill results could significantly enhance our understanding of the gold mineralisation system within the licence area, potentially unlocking value for shareholders.

We are committed to maintaining transparency and will provide further updates as activities progress. Our team remains dedicated to advancing this project responsibly, prioritizing safety and environmental stewardship.

Thank you for your continued support and confidence in our vision."
