Almonty's Sangdong Mine Enters Production Era as Analysts Split on Valuation

Almonty's Sangdong mine ships first tungsten concentrate, but the stock is down 21% in 30 days as Stifel and Goldman Sachs diverge on targets.

Tungsten has climbed near the top of the West's critical-materials agenda, and Almonty has just crossed the line that separates project developer from active producer. First tungsten concentrate has been produced at the company's Sangdong mine in South Korea — the first output from the complex after decades of dormancy — with initial units already packaged for export.

The milestone caps a long planning phase that, like most mining ventures, was marked by repeated delays. What matters now is execution: the second expansion phase is already under way and is slated for completion in 2027, when management targets annual capacity of up to 1.2 million tonnes. The processing plant currently runs seven days a week across multiple shifts, with preparations in place to move toward round-the-clock operation.

A Market That Has Already Repriced the Story

Investors have not greeted the news with unqualified enthusiasm. At a pre-market price of EUR 12.03, the stock sits 21% lower over the past 30 days and 42% below its 52-week high — a pullback that signals a meaningful reassessment by market participants after a stretch of generous advance praise. The shares are still up 51% year-to-date, trading at EUR 12.01.

That tension reflects a familiar pattern in raw materials: operational reality catching up with ambitious expectations. Producing saleable concentrate proves the equipment works. Getting from the first filled export bags to sustained, profitable large-scale output is traditionally the most delicate stretch in the mining sector, and it is precisely at this junction that some investors' confidence has wobbled.

Two Houses, Two Very Different Targets

The divergence in how analysts read the situation came into focus roughly two weeks ago, when coverage from two established houses began. Stifel issued a buy rating with a USD 25 price target, emphasizing future output capacity. Goldman Sachs took a decidedly more cautious line, assigning a neutral rating and a USD 13 target, arguing that the market has already priced in favorable tungsten-sector conditions and the demanding timeline.

The gap between the two — nearly double — captures the valuation dilemma facing shareholders. The question is how much optimism the stock can still carry at current levels.

Housekeeping Away From the Mine Site

Alongside the operational ramp-up, Almonty has been tidying its corporate affairs. Effective September 29, PricewaterhouseCoopers LLP took over as auditor from Zeifmans LLP. Auditor changes tend to trigger reflexive suspicion in capital markets, but the company stated the switch did not stem from any disagreement over accounting or audit procedures.

A legal clarification followed last Friday, when Pure Tungsten Inc. published a corrective notice as part of a settlement. The statement confirmed that Tiger Kim never held a management or board position at Almonty; his work as an independent contractor ended in 2015. Such disclosures clear away legacy issues, though they briefly divert attention from the operating business. Neither development, on balance, poses a structural threat — they are administrative clean-ups that a growing mining company has to work through.

Capital Discipline and a Long-Term Offtake

Management has also signaled financial capacity. Almonty repurchased 2,914,739 of its own common shares for approximately USD 48 million, to be cancelled. An automatic buyback program is planned, though it can be suspended or terminated at any time.

Beyond South Korea, the business base extends to the Los Santos mine in Spain, where a multi-year offtake agreement is in place with Wolfram Bergbau und Hütten AG, a subsidiary of the Sandvik group. The deal covers the fixed purchase of at least roughly 1,720 tonnes of contained WO? from existing tailings stock, and includes a conditional advance payment of USD 3 million. Contracts of this kind cushion market swings and provide financial visibility.

The Equation Remains Demanding

Tungsten's strategic value is beyond dispute, and a reliable supply source outside dominant monopolies draws ready interest from buyers. If the ramp-up succeeds, Almonty occupies a key position in a critical industrial metal outside China. Yet the transition to profitable continuous operation demands tight execution — and the market will judge every delay harshly. For now, the ore flow, not the project narrative, will decide the outcome.
