Environmental Achievements

• Gibraltar Mine's Environmental team recognized by the British Columbia Technical and Research Committee on Reclamation for outstanding work in mine reclamation and Indigenous collaboration.
• Florence Copper Project will have one of the smallest environmental footprints of any copper production facility in the world (water consumption 14 times lower, carbon emissions 6 times lower, energy consumption 3 times lower than conventional methods).

Social Achievements

• Gibraltar achieved outstanding safety performance for the year, with zero loss time incidents, zero days lost, zero loss time severity, and zero loss time frequency.
• 15% of new hires at Gibraltar were Indigenous.
• 28% of new hires at Taseko were female.

Governance Achievements

• Detailed Corporate Governance Policy and Practices outlined, including Board Committees and Diversity Policy.
• Independent Tailings Review Board in place for Gibraltar's tailings storage facility.

Climate Goals & Targets

Environmental Challenges

• Lower copper prices earlier in the year.
• Global pandemic (COVID-19) impacting operations and communities.

Mitigation Strategies

• Rigorous health protocols implemented at Gibraltar and Florence Copper to maintain operations and employee safety.
• Phased work-from-home plan implemented at Florence Copper.
• External audit of Gibraltar Mine's COVID-19 Safety Plan by Total Safety Services.

Supply Chain Management

Responsible Procurement

• Focus on local procurement (Gibraltar: $116.3 million, Florence Copper: $2.5 million)

Climate-Related Risks & Opportunities

Opportunities

• Florence Copper's low-carbon footprint.

Awards & Recognition

• Jake McDonald Mine Reclamation Award (Gibraltar)
• Metal Mine Reclamation Award (Gibraltar)

• Active mitigation of acid rock drainage at 28% of the Gibraltar Mine site.

Social Achievements

• 95% of Gibraltar Mine employees are local.
• 96% of wages and 38% of procurement at Gibraltar Mine are distributed locally.
• Three participation and cooperation agreements with local Indigenous groups.

Governance Achievements

• Management system for prevention of corruption and bribery throughout the value chain (details on page 41 of the report).

Climate Goals & Targets

Environmental Challenges

• Two notifications reported to the Ministry of Environment and Climate Change Strategy in 2021 related to water quality at Gibraltar Mine (elevated total suspended solids and surface drainage bypass).

Mitigation Strategies

• Investigated and addressed the elevated total suspended solids issue, attributing it to organics in the sample bottle.
• Re-established flow in the site collection ditch and captured bypassed water using a vacuum truck after a drainage bypass due to ice build-up.
