SunMirror AG (ROR1.VI) is a Switzerland-based investment holding company focused on acquiring equity stakes in pre-production mineral exploration companies, with emphasis on strategic mineral assets including sustainable green battery metals such as cobalt, lithium, and nickel, as well as copper and gold deposits in developed markets. The company explores and develops mineral properties primarily in Western Australia, holding interests in the Moolyella property, comprising one exploration license covering approximately 93 square kilometers in the East Pilbara Shire; and the Kingston-Keith project, consisting of one granted exploration license spanning 152 square kilometers in the Goldfields region; it aims to either advance these assets toward production or divest them to strategic buyers while expanding its portfolio with early-stage mining licenses in Europe to support secure supplies of battery raw materials. SunMirror operates through subsidiaries and targets institutional investors and strategic partners in the mining and electric vehicle supply chain sectors.
Originally founded in 2020 through the renaming of Dynastar AG following a reverse takeover of Couno Resources SA and headquartered in Switzerland, the company maintains its primary exploration activities in Australia with plans for European growth. In recent developments, SunMirror AG pursues a merger into its wholly-owned Swiss subsidiary SunMirror A AG (subsequently rebranded as BrightCore Resources AG), with shareholders approving the agreement on July 29, 2025, and the merger set to take effect on August 5, 2025, accompanied by a planned delisting from the Vienna Stock Exchange to streamline operations under the new entity. Earlier in 2025, the company announced an extraordinary general meeting on June 13 to propose the merger and issued a strategic update outlining paths for shareholder value, including asset sales or production; additional recent actions include a March 2025 decision to pursue legal summons in a dispute involving Pharlap Holdings Pte Ltd and MCC Australia Sanjin Pty Ltd, alongside a 2024 board resignation of director Daniel Monks.
