First IRMA Audit Report published: Carrizal’s Zimapán Mine

Today the Initiative for Responsible Mining Assurance (IRMA) took a bold step toward increasing transparency in the mining sector. With the release of the certification system’s first audit report (view report in Spanish), IRMA is demonstrating the type of clear, consistent reporting it provides for all stakeholders with an interest in mining. The release of this first audit report presents IRMA’s vision for the future of minerals sourcing—one in which information is readily available and objectively verified.

IRMA’s Standard for Responsible Mining represents a precedent-setting definition for responsible mining and also provides an unprecedented depth of information, opening the pathway to constructive conversation among diverse stakeholders, including those living closest to mines around the world. Through a certification system that is accountable to all stakeholders, IRMA seeks to drive meaningful, positive change in the mining industry.

A core tenet of IRMA is to improve accountability in the mining sector through increased transparency, with a commitment to sharing audit results publicly as a prerequisite for a mine to be independently audited. The first company to release a report in IRMA’s system is Carrizal Mining, a medium-sized lead, zinc, copper and silver miner in Mexico. Following an independent, third-party audit of the mine carried out by the IRMA-approved firm ERM Certification and Verification Services, Carrizal’s Zimapán Mine achieved IRMA Transparency, meaning it was assessed against all of IRMA’s relevant requirements and agreed to share its results publicly.

IRMA’s ultimate goal is to drive value for improved social and environmental responsibility in mining. Carrizal has shown how engaging in IRMA and undergoing an audit helps a mine on that journey. Their first step was self-assessment, followed by investments in improvements before the audit. Now, Carrizal’s leadership is using the audit results as a guide for where to focus next. By using the IRMA Standard for Responsible Mining as a guidebook throughout its journey, Carrizal Mining has taken important steps to learn where its mining practices meet global best practice and where there is room for further change. Most importantly, the mine’s leadership has used its engagement in IRMA to plan for improvements in its performance over time.

Carrizal Mine Site Assessment Announcement Stage 1

The Initiative for Responsible Mining Assurance (IRMA) is pleased to announce the commencement of a third-party independent assessment of the Carrizal lead, zinc, copper and silver mine against the IRMA Standard for Responsible Mining. The Carrizal mine, located in Mexico, is operated by Carrizal S.A. de C.V.

ERM Certification and Verification Services (CVS), an IRMA-approved certification body, will be carrying out the assessment, which includes a desk review (stage 1) followed by an onsite audit (stage 2).

Stakeholder Engagement in the Assessment

Interested stakeholders and members of the public can sign up to receive updates about the Carrizal mine assessment (e.g., the timing of the stage 2 onsite visit, link to pubic summary of audit results). The Mines Under Assessment page of IRMA’s website will also provide up-to-date information on all assessments.

Mine site stakeholders are invited to submit comments to ERM-CVS on the social and environmental performance of the Carrizal mine (in particular, how the performance of the mine site measures against the IRMA Standard for Responsible Mining).

Stakeholders of the Carrizal mine may also contact ERM-CVS if they are interested in being interviewed as part of the assessment process.

Stakeholder comments and expressions of interest in being interviewed as part of the audit process should be submitted by email or mail to:

ERM Certification and Verification Services


Mail: Exchequer Court, 33 St Mary Axe, London, EC3A 8A


Please forward this announcement, and feel free to contact ERM-CVS directly to provide names and contact information for other Carrizal stakeholders who may be interested in knowing about and participating in the mine site assessment process.
