• Human rights;
• Labour practices;
• Occupational health and safety;
• Environmental impacts;
• Business ethics and integrity;
• Responsible minerals sourcing;
• Supply chain due diligence;

Anonymous reports are accepted and all grievances are handled confidentially by authorized personnel to the extent possible.

NPM Silmet prohibits retaliation against any individual who raises concerns in good faith.

All grievances are assessed and addressed through a structured review, investigation, corrective action, escalation, and appeal process, where applicable.

The effectiveness of the grievance mechanism is reviewed periodically as part of NPM Silmet’s responsible sourcing due diligence program and continuous improvement activities.
