TECTONIC METALS APPOINTS EDUARD EPSHTEIN AS CFO, BOLSTERING EXECUTIVE TEAM FOR NEXT STAGE OF GROWTH

Tectonic Metals Inc. has appointed Eduard Epshtein, CPA, CA, as chief financial officer (CFO) and corporate secretary, effective Oct. 1, 2026.

Mr. Epshtein brings more than two decades of experience spanning capital markets, project development, strategic transactions and corporate finance. He joins Tectonic following a 16-year tenure as CFO of Lithium Americas Corp., where he helped build the company from an exploration-stage start-up into a New York Stock Exchange-listed lithium producer with a market capitalization that exceeded $5-billion (U.S.).

His appointment comes at a pivotal stage as Tectonic advances its flagship Flat gold project in southwestern Alaska, U.S., with a number of key catalysts ahead, including the completion of its largest-ever drill program at the end of October, a maiden mineral resource estimate for the Chicken Mountain intrusion target planned for the first quarter of 2027, followed by a preliminary economic assessment (PEA) targeted for the second quarter of 2027.

Tony Reda, co-founder, president and chief executive officer, commented:

"Eduard has already helped build what we are now building at Tectonic. He has taken a resource company from exploration through development and into production and understands first-hand what each stage demands -- from capital and corporate infrastructure to governance, strategic partnerships and execution. Having helped guide Lithium Americas from the TSX Venture Exchange to the TSX and ultimately the NYSE, while advancing major projects and completing significant financings and transactions, he brings experience that is directly aligned with the road ahead for our company.

"While that experience will be valuable as we advance Flat and consider our future capital markets strategy, it is Eduard's character that stands out most: He shares our long-term approach to building Tectonic and brings loyalty, integrity and commitment to the team. We are thrilled to welcome him."

Proven capital markets and corporate leadership experience

As CFO of Lithium Americas from its formation in 2007 through 2023, Mr. Epshtein helped build the company from an exploration-stage start-up with a small team into a major publicly traded lithium producer. During his tenure, Lithium Americas completed its initial public offering on the TSX Venture Exchange in 2008, graduated to the Toronto Stock Exchange in 2011 and listed on the New York Stock Exchange in 2018. He subsequently played a central support role in the separation of Lithium Americas into two independent public companies, including the NYSE listing of Lithium Argentina.

Mr. Epshtein also brings extensive experience advancing large-scale resource projects through successive stages of development. He helped advance the Cauchari-Olaroz lithium project in Argentina from exploration through construction and into production, with a design capacity of 40,000 tonnes per annum and approximately $1-billion (U.S.) of construction capital. He was also involved in advancing the Thacker Pass project in Nevada from exploration into construction, including the development of a multibillion-dollar financing strategy involving the U.S. Department of Energy and General Motors.

Throughout his career, Mr. Epshtein has executed a broad range of financings and strategic transactions, including project financing, convertible debt, at-the-market offerings, strategic investments, offtake arrangements and royalties. His experience also includes structuring joint ventures and strategic arrangements involving SQM, Ganfeng Lithium and General Motors, as well as significant M&A (merger and acquisition) transactions, including the Western Lithium-Lithium Americas merger, and the acquisitions of Millennial Lithium and Arena Minerals.

Beyond capital markets and project development, Mr. Epshtein brings broad public company leadership experience. At various stages of Lithium Americas' growth, he was responsible for financial reporting, finance, treasury, risk management, internal controls, information technology, corporate secretary functions, ESG (environmental, social and governance) reporting, board support, as well as legal and human resources.

Mr. Epshtein commented:

"Tectonic has reached an exciting stage in its evolution. I have spent much of my career helping build and advance resource companies through periods of significant growth, and I see many of the same ingredients here: a compelling project, an experienced and ambitious team, a strong financial position, and a clear long-term vision.

"What attracted me most to Tectonic is the opportunity to help build something meaningful and exciting. I look forward to working with Tony, the board and the entire Tectonic team as we advance Flat and build the financial, corporate and capital markets foundation to support the company through its next stage of growth."

Chief financial officer and corporate secretary transition

The company also announces that Oliver Foeste has stepped down as the company's CFO and corporate secretary, effective Oct. 1, 2026.

"I want to sincerely thank Oliver for his contributions over the past four years and for the partnership, counsel and friendship we have shared," added Mr. Reda. "He helped the company navigate a significant period of growth, including its financings, public company reporting requirements and governance. We are grateful for his contributions to Tectonic and wish him every success in the future."

Separately, the company announces the following grants under its equity incentive plan.

A total of 560,000 incentive stock options have been granted to an officer and an employee of the company to purchase up to 560,000 common shares in the capital of Tectonic.

The stock options have an exercise price of $2.05 per option share, expire five years from the grant date and vest over a 36-month period in three equal instalments every 12 months from the grant date.

A total of 51,000 restricted share units (RSUs) have been granted to an officer of the company. The RSUs vest over a 36-month period in three equal instalments every 12 months from the grant date.
