Almonty's Sangdong Test: A Replacement Filter Press, a Ten-Hour Run, and Two Trimmed Targets
Published on 11/09/2026 at 13:10 | Editorial boerse-global.de
Almonty's investment case now hinges on a single piece of machinery. The company confirmed in its latest commissioning update that a replacement filter press is being installed at Sangdong, the tungsten mine at the heart of its growth story — and until that swap demonstrably cuts the plant's breakdown rate, the gap between Almonty's strategic promise and its operating reality stays wide open.
The stock edged up 2.5% on Friday. That modest advance sits oddly against the week's news flow, which paired genuine metallurgical progress with the admission that technical trouble persists.
Quality climbs toward 50%, reliability lags
CEO Lewis Black reported that final-product quality is approaching the 50% mark — a tangible sign the processing circuit is maturing. The same update, however, described the commissioning problems as ongoing. The filter press being pulled was running at 40 tonnes per hour against a rated capacity of 80 tonnes per hour, which explains why management treats the replacement as central rather than cosmetic.
The round-the-clock operation that began on 1 November lasted just ten hours before a equipment failure halted it. Production restarted two hours later. That swift recovery counts in Almonty's favour, provided the underlying fault is fixed for good rather than patched. A better single reading on product grade only builds confidence if the surrounding plant steps hold up too — which is why steady throughput deserves more weight than any one progress headline.
Should investors sell immediately? Or is it worth buying Almonty?
Two brokers, one direction
Valuation pressure arrived from two directions on consecutive days. Nick Giles of B. Riley Securities cut his price target to US$20 from US$25 on 27 October, according to media reports, while keeping his Buy rating. Stifel had already trimmed its own target to US$21 from US$25 on 20 October, also retaining a Buy.
Stifel's move followed schedule updates around the company's investor day, with the brokerage pushing back its delivery assumptions for both Sangdong expansion phases. The pattern — conviction intact, numbers lower — argues for tracking operational milestones closely while the ramp-up still shows interruptions.
Washington's supply math favours Sangdong
The strategic backdrop gives the stock a floor of sorts. Cliff Nance, chief of Tungco, told the Korea Times on 27 October that Sangdong's output could help the United States reduce its tungsten dependence on China, describing mining in allied countries and US recycling as complementary routes rather than rivals.
That is a coherent role for Almonty inside a wider supply architecture. It only hardens into an investment thesis once the mine produces dependably. Strategic need and operational capability have to meet in the middle — and every debate about alternative supply chains should circle back to the practical question of how reliably Sangdong actually runs.

Gentung adds a second lever
Away from Korea, the Gentung tungsten project offers another angle. Montana joined the federal FAST-41 process roughly two weeks ago; according to Almonty, the change is meant to coordinate state and federal permitting timelines for projects such as Gentung. Better administrative plumbing helps only if it translates into practical speed, and Sangdong still carries more weight for the near-term view, given the operating experience and technical work already under way there.
The balance sheet of this story is therefore conditional but constructive: a plausible strategic horizon, a quality curve bending the right way, and a filter press that must prove itself. Until the plant demonstrates it can run without interruption, execution will count for more than the geopolitical narrative.
