Strategic Integration of Two Groundbreaking Product Lines
In 2025, TH MINING AG reached a milestone by integrating two innovative product lines under its flagship Diagria Bio brand, setting a new standard in sustainable agriculture and animal nutrition.

1. Diagria Bio – Soil Trading
Designed for advanced soil enrichment, Diagria Bio enhances soil fertility by delivering essential minerals while optimizing water management for crops. Recent trials, such as those in potato and maize cultivation in addition to other plants, have demonstrated significant yield increases, underscoring the transformative impact of this 100 % green product on sustainable farming practices.

2. Diagria Bio Tier – Animal Nutrition
As a mineral additive for animal feed, Diagria Bio Tier supports livestock increasing by providing a biologically sourced natural mineral solution. The product has generated exceptional interest, particularly among animal feed mills, due to its sustainable production and potential to improve animal well-being. The pending FIBL listing further positions Diagria Bio Tier as a trusted, high-value product for the organic feed market.

A Unified Vision for Growth
By aligning Diagria Bio and Diagria Bio Tier under a single brand, TH MINING AG has created a synergistic approach to sustainability. This integration enhances our product offering and reinforces our position as a leader in environmentally conscious solutions for agriculture and animal nutrition.

Key achievements
- Market Expansion in Switzerland: Following the successful inclusion of Diagria Bio in the Swiss Soil Enhancer List, the product became export-ready, achieving a significant 1,000-tonne order from subtraders within 24 hours of its listing.
- Increased Production Capacity: To meet growing demand, the production site in North Macedonia has scaled up to 50,000 tonnes annually, ensuring reliable supply for our global customers.
- Revenue Potential: The combined market entry of these two product lines opens lucrative opportunities in agriculture and animal feed, with high dividends forecasted for 2025.

Future Outlook
The integration of Diagria Bio and Diagria Bio Tier marks an important step in TH MINING AG’s growth trajectory. By leveraging our deep expertise in mining and resource management, coupled with a commitment to sustainable solutions, we are poised to deliver unparalleled value to our partners and clients.

Our journey with minerals has always been about uncovering potential. With Diagria Bio, we are not only transforming industries but also contributing to a more sustainable future. This is a story of innovation, resilience, and unparalleled growth—one that we are excited to share with our stakeholders.
