Alphamin Signs Deal to Supply Bisie Tin to New US Smelter
Alphamin to Supply Up to 3,600 Tonnes of Tin a Year From DRC to US Smelter
Alphamin Resources has agreed to supply tin concentrate from its Bisie mine in eastern Democratic Republic of Congo (DRC) to Nathan Trotter & Co., giving the Congolese mine a new outlet in the United States.
Under the initial two-year agreement, announced on 9 November 2026, Alphamin will allocate concentrate containing up to 3,600 tonnes of tin annually.
At the maximum allocation, the deal would account for 18% of Alphamin’s annual production guidance of 20,000 tonnes of contained tin.
The concentrate is destined for Tin Ridge, a US$65 million smelting and refining facility that Nathan Trotter is building in Henry County, north of Martinsville, Virginia.
The facility is designed to process both tin concentrate and scrap tin and is targeting first production in 2027. Alphamin did not disclose when shipments would begin.
Bisie, located in North Kivu province, produced 5,030 tonnes of contained tin in the third quarter of 2026, in line with Alphamin’s annual guidance.
Tin is used in solder for electronics and has applications in semiconductor manufacturing and other industrial processes.
Alphamin said it has been seeking to diversify its customer base since Abu Dhabi-based International Resources Holding acquired a 56% stake in the company in July 2025.
The Nathan Trotter agreement adds a US customer for part of Bisie’s output, while China remains Alphamin’s main market.
Alphamin said its diversification strategy aligns with the objectives of Pax Silica, a US-led initiative launched in December 2025 to strengthen supply chains for critical minerals and advanced technologies. The United Arab Emirates formally joined the initiative in January 2026.
