Alphamin to Restart Tin Production at DRC Mine Amid Improved Security

Bisie Mine Operations Resume as M23 Rebels Withdraw

US-based tin producer Alphamin is restarting operations at its Bisie tin mine in North Kivu, Democratic Republic of Congo (DRC). The company halted operations on March 13 due to advancing M23 rebel forces near the site.

However, the phased restart follows the withdrawal of rebel fighters toward Nyabiondo and Masisi, about 130km west of the mine. Alphamin confirmed that security remains under review as the area stabilizes.

During the shutdown, Alphamin still managed to sell and export 4,500 tonnes of tin between January 1 and April 8. An additional 280 tonnes remained in transit as of the latest update.

Tin Market Volatility Reflects Supply Concerns

The temporary closure of Bisie, combined with recent earthquakes in Myanmar, disrupted global tin supply. This led to a sharp rally in tin prices earlier this month.

On April 2, the LME three-month tin contract hit a three-year high of $38,175/t. However, news of Alphamin’s reopening, along with tariff-related uncertainty in the US, caused prices to correct. By today, tin prices settled at $31,000/t, down significantly but still elevated.

Tin production at the Bisie mine reached 4,270t in Q1, prior to the mid-March evacuation. Alphamin's ability to maintain logistical operations has helped stabilize exports despite the temporary halt in mining.

The Metalnomist Commentary

Alphamin’s return to production highlights how tin markets remain vulnerable to security risks in central Africa. With Myanmar also facing disruptions, the tin supply chain continues to face pressure. As geopolitical volatility becomes the norm, miners and manufacturers alike will need to build greater supply resilience.

Alphamin Restarts DRC Tin Production After Security Shutdown

Focus Keyphrase: Alphamin DRC Tin Production

Alphamin DRC tin production resumed this week following a temporary shutdown at the Bisie mine due to regional instability in eastern Congo. The phased restart began on 15 April, starting with ore stockpile processing and progressing to full underground mining later this month.

The Bisie tin mine, the largest industrial tin operation in the DRC, was evacuated in March after M23 rebels occupied nearby towns. Production halted on 13 March, and resumed only after the group withdrew from Walikale on 9 April. The evacuation led to a drop in first-quarter production to 4,720t of contained tin, down 18% from Q4 2024.

Tin Output and Sales Impacted by Security and Market Volatility

The disruption lowered Alphamin’s annual tin output target from 20,000t to 17,500t.

Sales in Q1 also dropped to 3,863t, a 22% decline compared to the previous quarter.

However, the company managed to sell 4,581t of contained tin by mid-April, showing signs of operational recovery.

Meanwhile, global tin prices remain volatile. The temporary mine closure, combined with an earthquake in Myanmar and new US tariff measures, led to large price swings.

The three-month LME tin price dropped to $30,700/t on 16 April, down from a three-year high of $38,175/t earlier in the month.

Ramp-Up Plans Underway Amid Ongoing Regional Risk

Alphamin expects full operational ramp-up within weeks. The gradual return of employees and restoration of underground mining will determine production stability in the near term. Security in eastern DRC remains a critical variable, affecting both production continuity and investor confidence.

The Metalnomist Commentary

Alphamin's quick operational recovery at Bisie highlights resilience but underscores the geopolitical risk in African mining. As tin prices remain volatile, secure and diversified supply will be key for downstream electronics and soldering markets.

ITSCI Withdraws from Walikale Amid M23 Conflict, Tantalum Supply Tightens

ITSCI, DRC

M23 Takeover Forces ITSCI Exit from Key Mining Territory

The International Tin Supply Chain Initiative (ITSCI) has halted operations in Walikale, North Kivu, Democratic Republic of the Congo (DRC). This withdrawal follows the March takeover of the region by the M23 rebel group, escalating risks for artisanal mining activities. Walikale is a key sourcing area for conflict minerals, particularly tantalum, tin, and tungsten, collectively known as the 3Ts.

Supply of Tantalum and Tin Faces Further Pressure

ITSCI’s withdrawal adds to earlier suspensions in other North and South Kivu territories, worsening supply disruptions. The DRC is a major global producer of tantalum, and traceable material from this region is critical to many buyers. As a result, spot prices for 25% minimum tantalite have jumped 26% since January, now trading at $95–102/lb cif main port.

Tin Prices Climb Following Closure of Alphamin's Bisie Mine

Meanwhile, US-based Alphamin suspended production and evacuated its Bisie tin mine in Walikale due to growing insecurity. This high-grade tin mine is among the largest in the DRC and has played a pivotal role in global tin supply. Tin futures on the LME have risen 14% since the mine's closure, highlighting the market’s sensitivity to regional conflict.

The Metalnomist Commentary

The exit of ITSCI from Walikale underscores the fragility of critical mineral supply chains in conflict zones. With both traceability and production disrupted, supply-side shocks are expected to ripple across electronics and defense sectors. As the geopolitical stakes rise, so too will the pressure on downstream companies to secure ethical and resilient sourcing.
