Alphamin Tin Boom Drives Record EBITDA as Costs Rise at Congo’s Bisie Mine

Alphamin Resources is on track to deliver record quarterly earnings as exceptionally strong tin prices continue to outweigh rising operating costs and weaker processing performance at its Bisie mine in the Democratic Republic of Congo.

The company, listed on the TSX Venture Exchange and Johannesburg’s AltX, expects second-quarter EBITDA of approximately US$167.3 million, up 6 per cent from US$157.8 million in the first quarter. The increase was driven overwhelmingly by higher tin prices rather than stronger production. Alphamin’s operating volumes remained largely stable, while lower head grades and recoveries placed upward pressure on unit costs.

Alphamin produced 5,013 tonnes of tin during the quarter and sold 5,014 tonnes, leaving production essentially unchanged from the previous three-month period. The Bisie operation has now reached approximately 20,000 tonnes of tin on a rolling four-quarter basis, broadly in line with its annualised production target. The major change came from pricing.

Average realised tin prices climbed 5 per cent to US$51,957 per tonne, while the broader market price approached US$53,000 per tonne. The increase generated enough additional revenue to more than compensate for higher operating expenses and weaker metallurgical performance. The result highlights the unusually strong cash-generating potential of Bisie at elevated tin prices.

Operating indicators were less encouraging beneath the strong financial headline. Ore processed increased 5 per cent to 211,034 tonnes, but the average tin grade declined from 3.4 per cent to 3.3 per cent. Recovery also weakened, falling from 74.2 per cent to 72.8 per cent.

The combination of lower grades and reduced recovery means that Alphamin had to process more material without achieving a corresponding increase in tin output. As a result, all-in sustaining costs increased 6 per cent to US$19,043 per tonne. The company attributed the higher cost base to increased royalties, export duties, marketing expenses, fuel and transportation costs, together with the timing of sustaining capital expenditure. Even after that increase, the difference between realised tin prices and AISC remained close to US$33,000 per tonne. That enormous operating margin explains why Bisie continues to generate substantial cash despite rising costs.

Alphamin’s net cash position declined from roughly US$140 million to US$90.7 million during the quarter. The reduction does not indicate a deterioration in underlying operating cash generation. Instead, it primarily reflects substantial distributions to shareholders and minority investors. The company paid or provided for approximately US$160 million in shareholder distributions, comprising around US$121 million for Alphamin shareholders, US$26 million for minority investors in its Congolese subsidiary and approximately US$13 million in associated withholding taxes.

Alphamin also paid roughly US$26 million in corporate tax. The large distributions demonstrate the extent to which high tin prices are translating directly into cash returns rather than being retained entirely on the balance sheet.

With current production already close to its annualised target, exploration is becoming increasingly important to Alphamin’s future valuation. The company increased drilling activity to 5,547 metres during the quarter. At the Mpama South target, visible cassiterite mineralisation was identified across intervals of 19.29 metres and 17.48 metres.

Laboratory assays are still pending, while an earlier drill hole returned 12.94 metres grading 2.10 per cent tin. Updated mineral-resource and reserve estimates are expected during the fourth quarter, potentially providing the next major catalyst for the company. Successful drilling could extend the mine’s resource base and provide greater confidence in the long-term sustainability of Bisie’s production profile.

Operational and security conditions were reported as stable, with the mine continuing to operate normally. Alphamin is nevertheless maintaining health-screening procedures following Ebola cases elsewhere in eastern Congo. The combination of exceptional ore grades, high margins and jurisdictional risk remains central to the investment case.

Bisie’s geological quality allows Alphamin to generate extraordinary margins when tin prices are strong. At the same time, the company’s exposure to the Democratic Republic of Congo means investors continue to apply a risk discount that would not necessarily exist for a comparable deposit in a lower-risk jurisdiction. That tension between high-quality tin production and geopolitical exposure remains one of Alphamin’s defining characteristics.

The immediate financial test is whether tin prices can remain above US$50,000 per tonne while royalties, logistics expenses and weaker recoveries continue to push costs higher. At current prices, Alphamin has considerable room to absorb those pressures while maintaining significant shareholder distributions. The risk becomes more apparent if tin prices retreat sharply.

Because production has remained broadly flat, the latest increase in EBITDA was primarily a pricing story rather than evidence of major operational improvement. A sustained decline in the tin market would therefore put much greater pressure on margins than the current record earnings suggest. For now, however, Bisie remains one of the world’s most powerful tin cash generators, with strong commodity pricing providing Alphamin with substantial financial flexibility while exploration offers the potential to extend the mine’s long-term growth profile.…Read more by Nikola
