Independently Assessing Mines

As the IRMA Standard is recognized and adopted around the globe, an independent, third-party assessment (audit) of a mining operation provides the transparency that enables deepened dialogue between mining companies, the communities potentially affected by the mining operations, and other stakeholders.

Detailed IRMA audit reports are independent evaluations of a mine’s environmental and social performance. These reports allow nearby communities, customers, investors, and even the mining company’s headquarters to gain information they need to understand what’s going well at each site—and what may require more attention. A third-party assessment under the IRMA Standard is not a one-time, but a step-by-step process toward continuous improvement.

The below chart of mines participating in the IRMA independent audit process can be sorted by clicking column headers. It can also be filtered using the search bar directly underneath the map above.
