The Initiative for Responsible Mining Assurance (IRMA) is pleased to announce the upcoming third-party independent surveillance assessment of the Carrizal Mine against the IRMA Standard for Responsible Mining. The Carrizal Mine is located near Zimapan in the Hidalgo province of Mexico. The on-site portion of the surveillance audit will occur 24-27 August 2022.

What is a Surveillance Audit?

A surveillance audit is a mid-cycle verification to ensure no material negative changes have occurred at a site. It is not a re-assessment of all IRMA requirements. Surveillance audits follow much of the same process as a certification audit and include document review, on site-assessment, and community and stakeholder engagement. An IRMA surveillance audit confirms continued performance against critical requirements, verifies ongoing regulatory compliance processes, and evaluates progress on corrective actions. It also follows up on stakeholder input received since the prior audit and areas of risk identified in the previous audit and confirms no major changes have occurred that would impact the previously assessed achievement level.

ERM CVS is the IRMA-approved certification body carrying out the surveillance assessment.
