IRMA Mine Site Assessment

Material origin

A specific mine site has undergone an independent third-party audit against the IRMA Standard for Responsible Mining, with a public audit report and a measured achievement level (IRMA Transparency, IRMA 50, IRMA 75, or IRMA 100) reflecting the share of the standard's requirements met.

You might see it written as: Initiative for Responsible Mining Assurance · IRMA Standard for Responsible Mining · IRMA 50 Achievement · IRMA 75 Achievement · IRMA 100 Achievement · IRMA Transparency · IRMA Assessed Mine

What it proves

What it does not prove

A pass/fail 'certified responsible' claim — IRMA reports measured performance levels, and lower levels mean substantial requirements are not yet met.
That minerals in a specific product came from the assessed mine, without separate chain-of-custody evidence.
Anything about downstream processing (smelting, refining) or the finished product's impacts.

Evidence checklist

Minimum authority: Third-party verified
Should state: Mine Site · Achievement Level · Audit Date · Audit Report Reference
Date sensitivity: Expiry matters — check the certificate is current.

IRMA is deliberately not a binary certification: IRMA 50 means roughly half the critical requirements are met — read the level, not just the logo.

Audit reports are public; the report is stronger evidence than the badge.
