May 30, 2022, Vancouver, BC – Taseko Mines Limited (TSX: TKO; NYSE MKT: TGB; LSE: TKO) (“Taseko” or the “Company”) has published its annual Environment, Social & Governance (“ESG”) Report, providing detailed information about the Company’s 2021 performance and outcomes against the most critical ESG topics and metrics for the global mining sector.

Stuart McDonald, President & CEO of Taseko, commented “Taseko’s annual ESG Report provides our many stakeholders – employees, local communities, governments, business partners and investors – with clear information about our performance on key sustainability topics. We believe we have a great story to tell.

Taseko is a growing and responsible producer of copper and other metals required to facilitate the global transition to a low-carbon future. With our North America-based operations, we hold ourselves to a high standard for operational excellence, for environmentally sound and socially responsible mining, for safe and healthy workplaces, and for sharing the economic benefits of our work.”

Mr. McDonald noted “Taseko’s focus on operational excellence translates into best-in-class ESG performance in key measures, such as energy efficiency, greenhouse gas (GHG) intensity, health and safety, and more.”

For the first time, in the 2021 ESG Report Taseko has established long-term goals in the areas of energy management, water management, reclamation and biodiversity. In addition, the Company is reporting against the Sustainability Accounting Standards Board (SASB) framework, providing consistent and comparable ESG metrics specific to the global mining sector.
