Copper Mark Assurance

Material origin

A specific copper-producing site (mine, smelter, or refiner) has been independently assessed against the Copper Mark's responsible production criteria, covering environmental, social, and governance issues, and holds the Copper Mark award subject to periodic re-assessment.

Issued by: The Copper Mark Company (via independent third-party assessors)

What it proves

A specific copper-producing site (mine, smelter, or refiner) has been independently assessed against the Copper Mark's responsible production criteria, covering environmental, social, and governance issues, and holds the Copper Mark award subject to periodic re-assessment.

What it does not prove

  • That the copper in a specific finished product came from an awarded site, unless supply-chain traceability is separately documented.
  • Low-carbon copper claims — the assessment covers responsible production practices, not carbon intensity.
  • Company-wide claims — the award applies to the assessed site only.

Expiry matters — check the certificate is current.

The Copper Mark is awarded per site and requires re-assessment on a set cycle — check the award is current.

The programme has expanded to related metals (e.g. zinc, nickel, molybdenum) under equivalent marks; confirm which metal and site the award covers.
