CULLINAN ANNOUNCES PROPOSED NAME CHANGE TO AUTOMATA RARE EARTH CORP.

Subject to regulatory approval, Cullinan Metals Corp. intends to change its name to Automata Rare Earth Corp. as part of the company's strategic transition toward rare earth element, copper and critical metal exploration.

In connection with the proposed name change, the company has reserved the trading symbol AREE with the Canadian Securities Exchange, subject to final approval by the Canadian Securities Exchange.

The company believes the new corporate identity better reflects its evolving focus on commodities that are increasingly essential to electrification, advanced technologies, artificial intelligence infrastructure, renewable energy systems, defence technologies and secure North American supply chains.

Rare earth elements have become strategically important due to their critical role in permanent magnets, electric vehicles, robotics, wind turbines, semiconductors, military technologies and next-generation electronics. At the same time, copper remains one of the foundational metals underpinning global electrification and energy infrastructure growth due to its widespread use in power grids, EVs, battery storage systems and data centre expansion.

Global concerns also continue to grow regarding concentrated supply chains as China currently dominates the majority of global rare earth production and processing capacity. Management believes the development of domestic North American sources of rare earth elements and critical minerals is becoming increasingly important amid rising geopolitical and industrial demand.

The company's Burnt Pond project in central Newfoundland remains a cornerstone asset within its growing critical metal portfolio. Located within the prolific Tally Pond volcanogenic massive sulphide belt, the Burnt Pond project hosts historical high-grade polymetallic mineralization including copper, gold, silver, zinc and lead, with mineralization remaining open along strike and at depth. The company believes the Burnt Pond project provides significant leverage to strengthening copper markets and growing electrification demand.

In addition, the company's Oculus rare earth project in central Labrador spans approximately 2,550 hectares within a recognized rare earth district and has returned historical surface sample values of up to 5.67 per cent total rare earth oxides, including a favourable heavy rare earth component.

The historical results referenced herein are derived from publicly available sources and historical assessment data, which have been independently verified by the company's qualified person as defined in National Instrument 43-101 (Standards of Disclosure for Mineral Projects), Derrick Strickland. However, readers are encouraged to review the company's news release dated April 24, 2026, available under the company's profile on SEDAR+, for additional technical disclosure relating to the Burnt Pond project and the Oculus rare earth project.

"Our new identity as Automata Rare Earth Corp. reflects the direction we believe global resource markets are heading," stated Christopher Huggins, chief executive officer. "Rare earth elements and copper are becoming foundational to the future of electrification, automation, robotics, AI infrastructure and national supply chain security. We believe this rebrand better positions the company as we advance a diversified critical minerals platform focused on commodities essential to the modern economy."

The effective date of the name change, together with the new Cusip number and ISIN of 052942109 and CA0529421095 for the company's common shares, is expected to be on or about June 10, 2026.
