SCS Seeks Input from Local Community and Other Stakeholders

Today, November 7, SCS Global Services announces that from December 8 to December 13, its auditors will visit Valterra Platinum’s Unki Mine in the Midlands Province, Zimbabwe, to conduct the on-site phase of its independent Renewal Assessment (audit) evaluating the site’s continuing performance against the Initiative for Responsible Mining Assurance (IRMA) Standard for Responsible Mining.

During the onsite visit, independent auditors from SCS Global Services will inspect the operation and associated facilities and collect feedback from local stakeholders – anyone directly or indirectly affected by the mine including community members, mine workers, and government officials.

The IRMA assessment results will be published on the IRMA audit page and available on request from the site. The IRMA audit report will describe how and why SCS Global Services scored Unki Mine against each of the 428 requirements of the IRMA Standard for Responsible Mining. The report will also  present an overall achievement level: IRMA Transparency, IRMA 50, IRMA 75, or IRMA 100.

8-13 December 2025

Your comments will help SCS Global Services assess the impact of Unki Mine on local communities and measure its performance against best mining practices. SCS Global Services invites you to sign up for an interview with auditors during the on-site visit, and/or submit written comments about Unki Mine using the contact details below.

Interviews can be held in Shona or English. Interviews requested by November 30 can be conducted remotely or in-person. Interview requests made after that date will most likely be conducted remotely but may also be conducted in-person if time permits, and remotely if it does not. Written comments can be submitted anytime until December 19.

Comments and interviews are confidential and interviews are conducted without mine personnel present. SCS Global Services does not share the names of stakeholder interviewees/commenters or copies of written comments with Valterra Platinum or IRMA. Only the general nature of comments will be summarized in the final audit report.

Valterra Platinum uses the results on environmental and social performance of the Unki Mine to improve its practices. Other stakeholders, particularly affected communities and mine workers, may use this audit report to engage with Valterra Platinum and others to improve the operation in the ways that matter most to them.

Unki underwent a comprehensive Initial Audit in 2021 achieving IRMA 75, followed 3 years later by an abbreviated Surveillance Audit to ensure site performance still supported its IRMA Achievement level and to monitor progress on the site’s Corrective Action Plan. Before the expiration of IRMA Achievement level, the operation completes a comprehensive Renewal Audit at which point the audit firm awards a new IRMA Achievement level. Ordinarily the entire initial-surveillance-renewal audit cycle takes 3 years, but because Unki was the first operation to complete the cycle the timeframe was extended to accommodate learnings and process improvements

Valterra Platinum’s Unki Mine is First to Undergo IRMA Renewal Audit

SCS Seeks Input from Local Community and Other Stakeholders

Valterra Platinum has signed agreements with the Initiative for Responsible Mining Assurance (IRMA), and IRMA-approved independent audit firm SCS Global Services (SCS), to continue to independently assess its Unki platinum operations against the IRMA Standard for Responsible Mining. Located in Zimbabwe’s Shurugwi region, Unki is the first mine in the IRMA system to undergo an independent Renewal Audit. Unki’s initial and surveillance audits occurred under Anglo American ownership. Valterra Platinum, a South Africa-based company, assumed site ownership on 31 May 2025.

IRMA Assessment Cycle

In the IRMA assessment cycle, a mining operation first undergoes a comprehensive Initial Audit and the independent audit firm awards an IRMA Achievement level, valid for 3 years. Midway between the publication of the initial audit and the expiration of the awarded IRMA Achievement level, the operation completes an abbreviated Surveillance Audit to ensure site performance still supports its IRMA Achievement and to monitor progress on the site’s Corrective Action Plan. Before the expiration of IRMA Achievement level, the operation completes a comprehensive Renewal Audit at which point the audit firm awards a new IRMA Achievement level. The Unki operation audit cycle has extended beyond 3 years because they were the first operation to be independently audited against the IRMA standard; the timeframe was adapted to accommodate learnings and process improvements.

SCS will conduct the Renewal Audit, which includes a desk review (stage 1) followed by an onsite audit (stage 2). When the assessment is complete, IRMA will publish a final report in which SCS re-evaluates, explains how and why they scored Unki against each of the 400+ requirements of the IRMA Standard, and awards an updated IRMA Achievement level.

Stakeholder Engagement in the Assessment

Interested stakeholders and members of the public can sign up to receive updates about the Unki Renewal Audit (e.g., the timing of the stage 2 onsite visit, link to public summary of audit results). IRMA’s Mines Under Assessment webpage also provides information on all independent assessments.

Members of the community, public officials, representatives of the workforce, or other organizations are invited to submit comments regarding how the mine site is managing their impacts to the environment including air, water, waste, greenhouse gases, and ecosystems; how the mine supports their workforce; and how the mine interacts with the surrounding community, and how it impacts the community, positively or negatively.

Interested parties may contact the independent audit firm, SCS, to share comments or to ask to be interviewed as part of the audit process. The audit firm can be reached via:
