The Copper Mark Assurance Process assesses responsible production as measured by the Copper Mark Criteria that cover 32 issue areas.  Each Copper Producer must undergo an independent third-party assessment at the site level in accordance with the Assurance Process.

The Copper Mark seeks to implement a comprehensive assurance process that is recognized by stakeholders as credible, incorporates best international practice, and aligns with the following five principles:

1. Pragmatic

The assurance process is achievable, implementable and fit-for-purpose. It enables participants to use documented evidence as a significant contribution to the assessment.

2. Inclusive

The assurance process is accessible to all Copper Producers, smelters and refiners at whatever stage along their journey to responsible production and to all sizes of operations.

3. Recognition

The assurance process recognizes existing standards systems, reporting frameworks, certifications or externally assured management to avoid redundancy and to promote the use of these initiatives.

4. Progressive

The assurance process acknowledges that a period of implementation is required to achieve full conformance with the Copper Mark criteria for responsible production (the Copper Mark Criteria).

5. Continuous improvement

The Copper Mark monitors overall progress in improvements against the Copper Mark Criteria through annual review of implementation of improvement actions.
