This overview brings together the standard’s key selfassessment tools and the guiding principles. The aim is to ensure that companies evaluate the effectiveness, consistency and development of their operations using uniform, transparent and internationally comparable criteria.
The operating principles behind the selfassessment tools steer the evaluation process and ensure that assessments are grounded both in legal requirements and in the voluntary commitment to continuous improvement.
The TSM standard’s tier system helps clarify how operations progress from basic requirements toward industryleading practices — from level C (minimum legal compliance) to level AAA (excellent, integrated and highperforming).
The assessment tools cover the core areas of mining operations: environment, safety, biodiversity, stakeholder engagement, tailings management, water management, climate, crisis preparedness and inclusive workplaces.
Results are verified every three years by independent, qualified experts to ensure the reliability and transparency of the assessment process.
