OZ Minerals recognises that the interface between contractor and company is a significant challenge in the management of safety, health, environment and social performance at our operations and activities. We aim to ensure the management systems and procedures of contractors engaged by OZ Minerals are consistent with our values, Code of Conduct, and Sustainability Standards.

In developing a consistent and aligned approach to safety the aim is to remove duplication of effort and where possible develop shared safety cultures.

As part of our tender process, potential contractors are screened in relation to safety, health, environment and social performance by subject matter experts. Contractors are selected through the OZ Minerals contractor selection process, which incorporates, but is not limited to the review of previous safety and health, environmental and social performance, contractor availability, competent persons, equipment in safe operating condition, cost, past performance and technical ability.

The majority of our operations have safety and health, environmental and social aspects in standard contracts. Martabe, Prominent Hill, Sepon and exploration also include human rights clauses in their standard contracts.
