Guided by our Health and Safety Policy, we strive to identify and mitigate health and safety risks. Both Eagle River and Kiena have Occupational Health and Safety Management Systems (OHSMS) that apply to all employees and contractors, and they operate Joint Occupational Health and Safety Committees.
Everyone has the right to refuse unsafe work. All employees and contractors complete a safety orientation before commencing work, and we rely on ongoing training and feedback to further improve our health and safety practices. Further details on how we manage this topic are available on our website.
In 2025, we held a workshop with our Senior Leadership Team (SLT) to define Wesdome’s health and safety vision. Together with TSM requirements, this vision informed an update of our Health and Safety Policy. We also developed a three year Health and Safety Strategy that we will begin to implement in 2026, and that will guide our work going forward.
Key components of the strategy include strengthening critical risk management and controls, enhancing leadership accountability and field presence, advancing incident prevention through leading indicators, improving contractor health and safety management, and reinforcing workforce training, engagement, and safety culture across all operations. We increased our capacity to manage health and safety during the reporting period by hiring a new Health and Safety Manager at Eagle River and hiring an additional Health and Safety team member at Kiena. Following the Angus acquisition, we began aligning the health and safety practices of our new team members with Wesdome’s standards and practices to promote alignment on training and behaviours.
During the reporting period, we integrated Enablon, a fit-for-purpose Environmental Health and Safety (EHS) software platform, across our operations allowing us to streamline the reporting, collection, management, and interpretation of health and safety data. This has enabled us to improve how we track incidents and corrective actions.
Annual Performance Summary
During the reporting period, we achieved a Total Recordable Incident Frequency Rate (TRIFR) of 1.0, the Company’s best result since we began measuring this data metric.1 We did not have any significant incidents of non-compliance with any provincial or federal health and safety laws during the reporting period, and we did not record any health and safety incidents that resulted in irreversible harm. A more detailed overview of our health and safety performance metrics is available in our ESG Data Book.
1 TRIFR is based upon the total number of medical treatments, lost time injuries and fatalities.

Occupational Health and Safety
Occupational Health and Safety In 2025, we took important steps to strengthen our health and safety culture by launching our Non-Negotiables. Specifically, we identified critical risk hazards with high severity potential and defined a set of critical controls for each of them. Each Non-Negotiable is also translated into a rule to avoid hazard exposure. Through a robust implementation campaign, we mobilize employees, supervisors, and managers to embed Non-Negotiables in our operations. This initiative was launched together with our Good Moves Program, which celebrates workers who demonstrate Wesdome’s core values of Safety, Ownership, Care, and Excellence (for more details, see Workforce Management). Continued deployment of our Non-Negotiables, including auditing for conformance, is a central component of our Health and Safety Strategy going into 2026.
We recognize that health and safety risks can be higher when employing contractors, who may not consistently have the same health and safety standards as Wesdome. In 2025, we began a contractor health and safety management program, which we plan to further roll out in 2026. This will include implementing systems to better align contractor health and safety standards with Wesdome’s and to verify that all contractors entering the site have proper training.
Incident Management
We seek to learn through any unwanted events, and when incidents occur, we investigate them, identify root causes, and implement corrective actions. In 2025, we implemented a Company-wide Incident Investigation and Internal Reporting Standard, which was developed in 2024.
In line with the Standard, incident investigations are done by a multi-disciplinary team that includes members of the Joint Occupational Health and Safety Committees, department managers, and field experts. In some cases, the investigation team may also include the COO, the Director of Health and Safety, or other members of leadership. We develop action plans based on the findings from incident investigations and assign both a responsible person and due date. To ensure actions plans are in compliance and follow-up, this information is entered into Enablon. Our investigation processes include contractors where relevant, ensuring that their experiences can inform the identification of corrective actions and support their own continuous improvement.
Security
Wesdome has security teams in place at both Eagle River and Kiena, which are managed by site Health and Safety Departments. Security staff perform security checks on vehicles and personal property entering and leaving our mine sites, and are responsible for ensuring that all those entering and exiting are accounted for and have the necessary site access approvals in place. We retain experienced, third-party security providers, and hold all security staff to the highest standard of conduct. We provide all security personnel with training on site-specific policies and procedures, including our zero-tolerance approach to bullying, harassment, the use of physical force, and the use of drugs or alcohol.
In 2025, with the goal of improving implementation of our Drug and Alcohol Policy, we increased the use of passive searches at both sites, and at Eagle River, we built a new security office. We did not receive any complaints related to our security practices during the reporting period.
Emergency Response & Preparedness
We strive to be prepared to respond to any emergencies that may arise and have site-specific emergency response plans and crisis management plans, as well as a Company-wide Crisis Management Plan. Since we conduct underground mining operations at both Eagle River and Kiena, we have mine rescue teams at both sites. Further details on how we manage emergency response and preparedness are available on our website.
In 2025, we expanded emergency response capacity at Eagle River to enable us to respond to surface emergencies. This included sourcing new equipment, including a fire truck, and providing surface rescue training to our team.
We also conducted one desktop crisis simulation exercise – a hypothetical cyberattack – to test our Company-wide Crisis Management Plan. We conducted a total of six mock emergency response drills in 2025, four at Eagle River, and two at Kiena.
In 2025, Kiena participated in its first mine rescue competition, while Eagle River hosted and participated in a district-wide mine rescue competition. However, total hours (including both Eagle River and Kiena) of mine rescue training decreased slightly from 9,908 hours in 2024 to 9,403 hours in 2025, reflecting a slight decrease in the number of mine rescue training members at Eagle River.
Training
Safety orientation is provided to all new workers to Wesdome including employees and contractors, prior to commencing work. This includes training on general site safety rules and policies, Personal Protective Equipment requirements, emergency response procedures, and our Drug and Alcohol Policy. In 2025, our focus was on leadership safety training, which was provided to anyone in a management position across the Company. During Wesdome’s Mental Health Awareness Month in May 2025, we also delivered training on mental health (for more details, see Workforce Management). In addition, we introduced a fit for purpose training module through Enablon to manage and measure training compliance against Wesdome standards across our operations.
