LAC · Lithium Americas Corp.

The appointment of Clayton Walker brings significant mining operational expertise to Lithium Americas' Board, particularly in copper but with broad applicability to lithium development. His leadership at Rio Tinto, overseeing major U.S. operations like Kennecott and Resolution Copper, positions him to guide Thacker Pass through construction toward late 2027 mechanical completion. As an independent director with no prior arrangements or material interests in Company transactions, Walker strengthens governance. His committee roles, effective post-2026 annual meeting re-election, focus on safety, sustainability, audit/risk, and technical matters critical for the Phase 1 40,000 tpa lithium carbonate project. Executive Chair Kelvin Dushnisky emphasized Walker's U.S. regulatory knowledge as key for stakeholder value creation amid the JV with GM and DOE financing.
