ALPHAMIN TO SUPPLY BISIE TIN CONCENTRATE TO NEW US SMELTER

Alphamin Resources Corp. has signed an agreement to allocate a portion of tin concentrate production from its Bisie tin mine in the Democratic Republic of the Congo to Nathan Trotter & Co. Inc., a United States-based tin refiner currently completing the construction of its smelting facility.

The allocation of up to 3,600 tonnes of contained tin per annum, for an initial period of two years, represents just under 20 per cent of Bisie's targeted production.

Tin is increasingly recognized as a critical mineral for the global economy, with applications spanning electronics, semiconductors, advanced manufacturing and the technologies foundational to the artificial intelligence era. The establishment of NT's U.S. smelting facility represents a significant step in building western tin refining capacity and diversifying global tin supply chains.

Bisie is the world's highest-grade primary tin mine, currently producing approximately 20,000 tonnes of contained tin per annum. The mine's success would not have been possible without the long-term support of the government of the Democratic Republic of the Congo, and the continuing efforts of the international community, including the U.S. government, to promote stability in eastern DRC. The allocation to NT establishes Bisie as a supply source for NT's new U.S. smelting operations and marks an important step in building a diversified global customer base for Bisie's high-grade tin concentrate.

Following the acquisition of a majority interest in Alphamin by International Resource Holding, a leading United Arab Emirates-based investment group, Alphamin has been actively seeking to diversify its customer base and to support the development of western tin refining capacity. This strategy is consistent with the objectives of Pax Silica, a United States-led initiative launched in December, 2025, to build secure and resilient supply chains for critical minerals and technologies foundational to the AI era. The UAE plays a recognized role as a partner in the Pax Silica framework, and IRH is supportive of this arrangement.
