Given the inherently high-risk profile of mining and recognising that our people are our most valuable asset, ensuring employee safety is a key measure for our corporate success.

Health, safety and wellbeing focus areas

Systematically Managing Risks

Managing health and safety risks is at the centre of our approach to safety and is underpinned by our Occupational Health and Safety Management Systems. This management system follows best practice, in line with recognised international practices, and is externally certified to ensure compliance amongst mining units.

In 2024, we received the DNV Level 8 Occupational Health and Safety Management System rating, becoming the first mining company to obtain it, reflecting our unwavering commitment to upholding the highest safety standards. You can find the Inmaculada and San José DNV ISRS Certificates here.

To ensure a safe working environment, we implement a systematic risk management approach, supported by our Occupational Health and Safety Management System. In 2023, we carried out internal audits which were conducted by internal Hochschild-trained auditors. Our OHS Management System applies to all sites, Hochschild employees and contractors.


Investigating and Learning

All Incidents are investigated promptly and appropriate response measures were implemented. We remain committed to health and safety by continuing to promote the improvement of all activities and assess the potential occurrence of HPEs. In the event of an HPE occurring, our CEO leads a meeting with the

COO and all the Operational Unit Managers to review the internal investigation. In this meeting, the root causes are discussed, and control actions are reinforced at the corporate level to share the lessons learned with the entire organisation.

During 2023, six HPEs were evaluated. We continue to work to reduce this number of HPEs to zero through a range of initiatives:

  • We improved the fatigue control system installed in all our buses and 4x4 pickup trucks in Peru to enhance road safety in the transportation of personnel between cities and mine sites. This system collects data analysed through a business intelligence dashboard to predict potential incidents.
  • Our Peruvian and Argentinian operations implemented a smartwatch/wristband for all personnel who operate heavy machinery. This smartwatch/ wristband monitors sleep time to prevent fatigue at work which can increase the risk of incidents.
