ERM CVS Meminta Masukan dari Masyarakat Setempat dan Pemangku Kepentingan Lainnya untuk melengkapi proses penilaian audit IRMA

5 November 2025, ERM Certification and Verification Services (ERM CVS) mengumumkan bahwa pada 1–5 Desember 2025, tim auditor independen akan mengunjungi operasi pertambangan PT Vale Indonesia di Sorowako, Sulawesi Selatan, untuk melaksanakan tahapan penilaian lapangan sebagai bagian dari proses peninjauan atas standar Initiative for Responsible Mining Assurance (IRMA). Audit independen ini bertujuan untuk mengevaluasi kinerja operasi tambang berdasarkan Standar IRMA untuk Pertambangan yang Bertanggung Jawab. ERM CVS merupakan lembaga audit independen pihak ketiga yang telah disetujui oleh IRMA untuk melakukan audit berdasarkan standar tersebut.

Selama kunjungan lapangan, tim auditor ERM CVS akan meninjau area operasi tambang dan fasilitas terkait, serta mengumpulkan masukan dari para pemangku kepentingan lokal — termasuk anggota masyarakat, pekerja tambang, pejabat pemerintah, dan pihak lain yang secara langsung maupun tidak langsung terdampak oleh kegiatan pertambangan.

Setelah audit selesai, hasil penilaian akan disajikan dalam laporan publik yang akan diterbitkan secara lokal dan di situs resmi IRMA (Inggris). Laporan ini akan menjelaskan penilaian PT Vale Sorowako terhadap lebih dari 400 persyaratan dalam Standar IRMA, beserta alasan penentuan setiap skor yang diberikan. Audit ini juga akan menentukan tingkat capaian keseluruhan: IRMA Transparency, IRMA 50, IRMA 75, atau IRMA 100 (Inggris).

Hasil audit ini akan membantu PT Vale Indonesia dalam meningkatkan praktik pertambangan yang bertanggung jawab. Bagi pemangku kepentingan — terutama masyarakat sekitar dan pekerja — laporan ini menjadi sarana untuk berdialog secara setara dengan perusahaan terkait hal-hal yang paling penting bagi mereka.

ERM CVS to Conduct On-site IRMA Assessment of PT Vale Indonesia Tbk’s Sorowako Mine

5 November 2025By

From IRMA approved independent auditor ERM CVS. View/download the announcement in Bahasa Indonesia.

ERM CVS Seeks Input from Local Community and Other Stakeholders

5 November 2025, ERM Certification and Verification Services (ERM CVS) announces that from 1-5 December 2025, an independent audit team will visit PT Vale Indonesia’s Sorowako mining operations in South Sulawesi, Indonesia, to conduct the on-site phase of its Initiative for Responsible Mining Assurance (IRMA) assessment. This independent audit evaluates the operation’s performance against the IRMA Standard for Responsible Mining. ERM CVS is an independent, third-party audit firm approved by IRMA to perform assessments against its standard.

During the on-site visit, ERM CVS auditors will tour the mine and its associated facilities and collect feedback from local stakeholders — including community members, mine workers, government officials, and others directly or indirectly affected by the operation.

Upon completion, the audit will result in a publicly available report, published on the IRMA audit page. The report will outline how PT Vale’s Sorowako operations performed against more than 400 requirements of the IRMA Standard, providing detailed explanations of the scores assigned. The audit will also determine an overall achievement level: IRMA Transparency, IRMA 50, IRMA 75, or IRMA 100.

The audit findings will enable PT Vale Indonesia to enhance its responsible mining practices. For stakeholders —particularly community members and workers — the report provides an opportunity to engage constructively with the company on areas of shared concern and improvement.

1 – 5 December 2025

ERM CVS invites all stakeholders to participate by sharing feedback or requesting an interview with the auditors. Your insights will help assess the social, environmental, and economic impacts of PT Vale’s operations and measure its alignment with responsible mining best practices.

Interviews can be conducted in English or Bahasa Indonesia. Requests submitted by 21 November 2025 can be scheduled in-person or remotely. Requests made after 21 November will be accommodated as time permits. Written comments can be submitted until 5 December 2025 to be included in the audit.

Anglo American’s Barro Alto Nickel Mine Completes IRMA Surveillance Audit

31 October 2025By

On 31 October 2025 the Initiative for Responsible Mining (IRMA) released the surveillance audit report of Anglo American’s Barro Alto nickel mine, located in Brazil’s state of Goiás. IRMA-approved audit firm ERM CVS conducted the audit and assessed the progress made on the corrective action plan that the operation committed to in the initial audit report. Throughout the surveillance audit, ERM CVS found Chapter 2.2 – Free, Prior and Informed Consent of the IRMA Standard for Responsible Mining as relevant and this chapter will be fully evaluated during the renewal audit.

IRMA’s independent assessment cycle occurs in 3 stages: (1) initial audit, (2) surveillance audit, and (3) reassessment audit. Mines in the IRMA system must undergo a surveillance audit during each 3-year audit cycle, and this audit must occur between 12 and 18 months after an initial audit report has been publicly released. Surveillance audits are not full audits, meaning that conformance with all requirements reviewed in the initial audit does not need to be re-established. Typically, during a surveillance audit the audit team verifies that the mine’s systems and controls are still in place and are functioning effectively, that no major changes have occurred since the initial audit that negatively affect the mine’s performance. The surveillance audit includes confidential interviews with workers and engagement with Indigenous rightsholders and community stakeholders. The initial and surveillance IRMA audit reports for the operation are available on the Barro Alto Mine audit page on the IRMA website.

As the IRMA Standard is recognized and adopted around the globe, these audits are important steps in a deepening dialogue between mining companies and those affected by their operations. Because the IRMA process is always improving from the experience of the most recent audit, audit results should be reviewed and interpreted accordingly.

On February 18, 2025, Anglo American announced the sale of the Barro Alto operation to MMG Singapore Resources Pte. Ltd, a wholly owned subsidiary of MMG Limited. The sale of the operation is subject to a number of conditions, including customary competition and regulatory clearances, with completion of the sale expected by Q3 2025.

The independent IRMA system is the only global mining standard that provides equal power to the public sector (communities and Indigenous rights holders, mine workers, and environmental and human rights advocates) alongside the private sector (mining companies, mined materials purchasers and investors).

NOTE: A Portuguese language version of this report will be published within the next week.

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

10 October 2025By

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:

Gerdau’s Várzea do Lopes Iron Ore Mine Completes IRMA Audit

9 October 2025By

Brazilian Mine achieves IRMA Transparency when audited against the world’s only equally governed mining standard

On 9 October 2025 the Initiative for Responsible Mining (IRMA) released the audit report of Gerdau’s Várzea do Lopes iron ore mine against the IRMA Standard for Responsible Mining. The Várzea do Lopes Mine is located in Brazil’s Minas Gerais state in the municipality of Itabirito. Independent audit firm SCS Global Services assessed the Várzea do Lopes Mine at IRMA Transparency when measuring its performance against the Standard’s best practice social and environmental criteria.

IRMA Transparency means that the operation has been independently audited against all relevant requirements in IRMA’s Standard and has publicly shared its audit scores and the basis for auditors’ findings. By sharing such extensive information, a mine provides diverse stakeholders with the information needed to understand the mine’s operations and encourage improvement as needed. The full audit report is available on the Várzea do Lopes Mine audit page on the IRMA website.

As the IRMA Standard is recognized and adopted around the globe, these audits are important steps in a deepening dialogue between mining companies and those affected by their operations. Because the IRMA process is always improving from the experience of the most recent audit, audit results should be reviewed and interpreted accordingly.

On July 17, 2025, Gerdau announced the signing of an agreement for the full transfer of mining rights related to the operation of the Várzea do Lopes Mine, located in Itabirito (MG). The new holder of these rights is Várzea do Lopes Mineração S.A., a company controlled by the same partners of Avante Participações e Negócios Ltda.

With this transaction, the new holder of the mining rights assumes full responsibility for the operation and production of iron ore at the Várzea do Lopes Mine.

This initiative is part of Gerdau’s process of reorganizing its mining assets, aiming to concentrate its own mining operations in the Miguel Burnier asset, located in Ouro Preto (MG).

Including the Várzea do Lopes Mine, 26 industrial-scale mines worldwide are within the IRMA independent assessment system. After an initial self-assessment, a participating mine engages a third-party audit firm — trained and approved by IRMA — to conduct a detailed independent evaluation, including on-site visits to the mine and nearby communities. Following the release of the initial audit, a surveillance audit checks on the mine’s performance. Three years after the initial audit, the operation is fully audited again.

The independent IRMA system is the only global mining standard that provides equal power to the public sector (communities and Indigenous rights holders, mine workers, and environmental and human rights advocates) alongside the private sector (mining companies, mined materials purchasers and investors).

Mina de minério de ferro Complexo Várzea do Lopes da Gerdau completa auditoria da IRMA

9 October 2025By

Mina brasileira alcança IRMA Transparência após ser auditada de acordo com o único padrão de mineração do mundo com governança igualitária

9 de outubro de 2025 – A Iniciativa de Asseguração de Mineração Responsável (IRMA) publicou o relatório de auditoria do Complexo Várzea do Lopes, da Gerdau, com base no Padrão IRMA para Mineração Responsável. A Complexo Várzea do Lopes está localizada no estado brasileiro de Minas Gerais, no município de Itabirito. A empresa de auditoria independente SCS Global Services avaliou a Complexo Várzea do Lopes com o IRMA Transparência ao medir seu desempenho em relação aos critérios sociais e ambientais de melhores práticas da Padrão.

IRMA Transparência significa que a operação foi auditada de forma independente em relação a todos os requisitos relevantes do Padrão IRMA e que compartilhou publicamente suas pontuações de auditoria e a base para as conclusões dos auditores. Ao compartilhar essas informações abrangentes, uma mina fornece às diversas partes interessadas as informações necessárias para compreender as operações da mina e incentivar melhorias, conforme necessário. O relatório completo da auditoria está disponível na página de auditoria do Complexo Várzea do Lopes no site do IRMA.

Como o Padrão IRMA é reconhecido e adotado em todo o mundo, essas auditorias são etapas importantes em um diálogo mais profundo entre as empresas de mineração e as pessoas afetadas por suas operações. Como o processo IRMA está sempre melhorando com base na experiência da auditoria mais recente, os resultados da auditoria devem ser revisados e interpretados de acordo.

Em 17 de julho de 2025, a Gerdau anunciou a assinatura de um acordo para a transferência integral dos direitos minerários relacionados à operação da Mina Várzea do Lopes, localizada em Itabirito (MG). A nova detentora desses direitos é a Várzea do Lopes Mineração S.A., empresa controlada pelos mesmos sócios da Avante Participações e Negócios Ltda.

Com essa transação, o novo detentor dos direitos minerários assume total responsabilidade pela operação e produção de minério de ferro no Complexo Várzea do Lopes.

Esta iniciativa faz parte do processo de reorganização dos ativos de mineração da Gerdau, com o objetivo de concentrar suas operações de mineração no ativo Miguel Burnier, localizado em Ouro Preto (MG).

Incluindo a Complexo Várzea do Lopes, 26 minas de escala industrial em todo o mundo estão dentro do sistema de avaliação independente da IRMA. Após uma autoavaliação inicial, uma mina participante contrata uma empresa de auditoria externa – treinada e aprovada pela IRMA – para realizar uma avaliação independente detalhada, incluindo visitas in loco à mina e às comunidades próximas. Após a liberação da auditoria inicial, uma auditoria de controle verifica o desempenho da mina. Três anos após a auditoria inicial, a operação é submetida novamente a uma auditoria completa.

O sistema independente IRMA é o único padrão global de mineração que oferece poder igual ao setor público (comunidades e detentores de direitos indígenas, trabalhadores de minas e defensores dos direitos humanos e ambientais) e ao setor privado (empresas de mineração, compradores de materiais extraídos e investidores).
