Alphamin guides for record 20,000 tonnes of tin from Bisie in 2026

Alphamin Resources has guided for approximately 20,000 tonnes of contained tin production in the year to December 2026 from its Bisie mine in North Kivu province, Democratic Republic of Congo, an increase on the record 18,576 tonnes it produced in 2025.

A record year despite disruption

The 2025 record came despite a significant operational disruption: Alphamin suspended production at Bisie on 13 March 2025 after Rwanda-backed M23 rebels advanced toward the Walikale district where the mine is located. The mine resumed a phased return to operations the following month once insurgents withdrew roughly 130km east of the site, allowing the company to end the year at a new production high regardless of the lost weeks.

A globally significant, high-grade deposit

Bisie produces around 6% of the world's annual tin supply and is regarded as the highest-grade tin mine in operation anywhere, giving Alphamin a cost advantage even when logistics or security disruptions force temporary halts. That grade advantage has helped the company remain profitable through a period when few other tin producers have had to manage comparable conflict-related risk.

Why the guidance matters

Higher tin prices through 2025 and 2026 have improved the economics of Bisie's expansion, and a full year of uninterrupted operations in 2026 would let Alphamin capture the benefit of both higher output and stronger prices simultaneously. Tin is a critical input for solder used in electronics manufacturing, giving Bisie's output outsized importance to global supply chains relative to the DRC's small share of overall global mining investment.

What could go wrong

The conflict in eastern DRC remains unresolved, and a renewed rebel offensive could again threaten operations at Bisie, as it did in March 2025. Alphamin's guidance assumes a continuation of the relative calm that has held since the insurgent withdrawal, a assumption the company itself has acknowledged carries risk given the volatile security situation in North Kivu.
