Dear valued clients & industry partners,

We wish to formally notify our clients, mining houses and industry partners of an important development regarding the marketing and distribution structure of PolyStem Tamping Capsules within South Africa and the broader African market

Following recent business and ownership restructuring within the product supply chain, Vigario Maintenance & Mining Services (Pty) Ltd (VMMS) will with immediate effect, act as the exclusive Marketing and Distribution Company for PolyStem Tamping Capsules, previously known as Plystem Tamping Capsules.

Updated VMMS-branded packaging will gradually be introduced to ensure consistent product identification and supply control.
We would like to emphasize that this change does not affect the product specification, quality or application. The capsules will continue to be manufactured by our amalgamated established OEM partner who have historically supplied this product to the market.

Our OEM partners will continue to service and support existing mining house and clients, ensuring uninterrupted supply. To ensure proper brand management and supply chain control, all future distribution will be coordinated through Vigario Maintenance & Mining Services (Pty) Ltd. Where required and approved by VMMS, supply partners may apply identification stickers to VMMS packaging for operational purposes.

To maintain product authenticity, quality control and supply chain integrity, PolyStem Tamping Capsules will progressively be distributed in VMMS – approved packaging and identification. Clients and industry partners are encouraged to source product only from VMMS or approved supply partners operating under VMMS authorization.

This approach ensures:
• Proper product traceability
• Responsible pricing structures
• Sustainable manufacturing and supply partnerships

VMMS will continue working closely with our manufacturing and distribution partners to ensure uninterrupted supply and ongoing support to all existing mining operations.

This restructuring follows a comprehensive review of historical market supply conditions. Over time market pricing pressures created unsustainable practices, placing strain on manufacturing partners and long-term supply reliability. The revised distribution model establishes a structured, stable and commercially sustainable framework that benefits all stakeholders.

Our objectives through this initiative are to ensure:
• Long-term supply stability for mining operations
• Sustainable manufacturing and supply partnerships
• Consistent product quality and traceability
• Structured and transparent market distribution
• Continued support to existing clients and operations.

Vigario Maintenance & Mining Services (Pty) Ltd remains committed to supporting the mining industry with reliable products, responsible supply practices and strong partnerships.

We appreciate your continued support and look forward to working with you under this improved supply structure.
Should you require any additional information or clarification, please contact us directly.

Yours sincerely,
Dirk Swart
Managing Director Vigario Maintenance & Mining Services (Pty) Ltd
