External Verification

How Verification Works

Within Towards Sustainable Mining (TSM), a process of external verification was established to ensure that companies’ reporting on TSM  performance indicators is consistent, accurate and transparent.

Every three years, a trained and accredited verifier critically reviews a company’s self-assessments to determine if there is adequate evidence to support the performance ratings reported. Verifiers are experienced independent auditors and technical experts. If necessary, verifiers can change companies’ self-assessed ratings to ensure they accurately reflect evidence of the facility’s management practices and performance.

In conducting an external verification, the verifier and the company that they are verifying must adhere to the requirements of the Terms of Reference for Verifiers,
linked below. This includes requirements such as: advance notice of the verification to communities of interest, recognized audit credentials for verifiers, and a quality review of verifications by a third party.

Becoming a TSM Verifier

Individuals interested in becoming TSM verifiers should confirm they meet the conditions outlined in the TSM Terms of Reference for Verifiers. After confirming this, individuals should complete the TSM online training program at their own pace or register for the Mining Association of Canada’s annual verifier training workshop. See the TSM Training page for more details. Finally, individuals should reach out to organize a follow-up call with MAC’s Director of TSM, Katherine Gosselin. 

Verification Resources

The following resources are available for verifiers as well as companies undergoing external verification.

Terms of Reference for Verifiers

TSM Verification Guide

The TSM Verification Guide provides verifiers with guidance on expectations related to the verification process, and includes in appendices the Terms of Reference for Verifiers, Verification Oversight Policy, and a template for a public Verification Summary Report.

TSM Verification Oversight Process

The TSM verification oversight process aims to ensure that active verifiers conform with the Terms of Reference for Verifiers and that they demonstrate sound interpretation and application of TSM protocol requirements. The process includes direct oversight of verifiers, a general evaluation of effectiveness of certain elements of TSM verification, and an annual report to share findings and recommendations.
