QUITO, Nov. 20, 2024 - Solaris Resources Inc. (TSX: SLS; NYSE: SLSR) ("Solaris" or the "Company") is pleased to announce the final steps to complete its emigration by year-end following the Company's previous announcement to position the Company to maximize returns for shareholders and protect the interests of stakeholders by aligning with regulators in Ecuador as Warintza completes the permitting process (see the Company's news release dated September 9, 2024).

In connection with the emigration, the Company is pleased to announce the appointment of Matthew Rowlinson as President and Chief Executive Officer of the Company, effective January 1, 2025, to be based in a new office in Zug, Switzerland, with further appointments in this office to follow. Mr. Rowlinson is uniquely well positioned for this role having most recently served as the Head of Copper Business Development for Glencore, one of the world's largest copper miners.

The Company is also pleased to announce the appointment of Mr. Matthew Rowlinson, Mr. Rodrigo Borja, and Mr. Hans Wick to the Company's board of directors effective January 1, 2025. The Company's directors in Canada, Mr. Daniel Earle, Ms. Poonam Puri, Mr. Kevin Thomson and Mr. Ron Walsh will resign from their roles on the board effective January 1, 2025.

Mr. Rowlinson will lead the executive team and be supported by the Warintza Project team led by the Company's Chief Operating Officer, Mr. Javier Toro. Mr. Toro has built a technical team based in Lima, Peru, with recent hires from senior copper mining companies as Project Director, Senior Resource Geologist, Geotechnical Manager, Senior Metallurgical Engineer, and Mine Planning Engineers. Additionally, Mr. Toro will continue to be supported by Ecuadorian executives, Mr. Jorge Fierro, Vice President, Exploration, and Mr. Ricardo Obando, newly promoted to the role of Vice President, Community and Government Affairs, both of whom have been with Solaris since inception.

Placement and Spin-Out
In connection with his appointment, Mr. Rowlinson has agreed to subscribe for C$500,000 of common shares from the Company pursuant to a private placement.

The Company anticipates completing a spin-out transaction to capitalize on its non-core assets, including La Verde, Capricho, and Paco Orco, which will form the foundation of a new growth-oriented copper company focused on the consolidation of operating and advanced development assets with exceptional upside potential. This new company will benefit from the deep knowledge of the universe of projects and extensive network of relationships Mr. Rowlinson brings to Solaris to rapidly scale its business. The Company will announce additional details about this exciting venture in the new year.

Executive Chairman's Message
Mr. Richard Warke, Executive Chairman of Solaris, commented, "I want to offer my sincerest gratitude to the Solaris team for their unrelenting drive to advance the late David Lowell's greenfield discovery at Warintza to become a major copper project more than ten-times its original size in only five years.

As early works infrastructure development is now underway, this team has brought Warintza within view of completing permitting and commencing full-scale construction for what could be one of the industry's last major copper districts to be developed at low elevation and adjacent to infrastructure. I would also like to thank the outgoing directors for their guidance during this journey.

I am firmly committed to maximizing returns for shareholders and protecting the interests of stakeholders and this reorganization creates the strategic flexibility and alignment of interests with regulators to do so. I want to welcome Matt and the incoming directors to Solaris as we position ourselves for a pivotal year ahead."
