Alphamin Resources has entered into an initial two-year supply agreement for up to 3,600 tonnes of contained tin per year with US refiner Nathan Trotter & Co. The tin concentrate will come from its Bisie mine (located in North Kivu,
Democratic Republic of the Congo), recognized as the highest-grade primary tin mine in the world. This 3,600-tonne volume accounts for just under 20% of Bisie’s targeted annual production (which stands at approximately 20,000 tonnes per year).
These shipments will feed the new $65 million Tin Ridge smelter built by Nathan Trotter in Henry County, Virginia. This partnership falls directly under Pax Silica, a US-led initiative aimed at securing Western supplies of critical minerals (specifically for electronics, defense, and AI). The Pentagon had previously allocated $19 million to Nathan Trotter to support the project.
Until now, about 70% of Alphamin’s concentrate was exported to the Yunnan Group in China. This commercial diversification effort was accelerated under the impulse of Emirati investor International Resource Holding (IRH), which has become Alphamin’s majority shareholder.
