Minerals Sourcing+Third-party Certification Audits Publication (Step 4.4)+methodology

According to the OECD Guidance, Smelters or Refiners (SoRs), or the third party auditors, should be publishing these results. Nevertheless, sometimes other companies share this information, and this metric is designed to capture these cases.
The answer will most likely be found in a Responsible Sourcing Policy, Code of Conduct, Sustainability Report or Conflict Minerals Report. If the company mentions the following third-party auditors which publish results, they receive a 'Yes': Responsible Minerals Initiative (RMI), London Bullion Market Association (LBMA), or Responsible Jewelery Council (RJC)
