Almonty Industries Inc. (ticker: ALM) has crossed a critical milestone: its Sangdong tungsten mine in South Korea is now officially commissioned as of March 2026. The move transforms what was once a development project into a revenue-generating operation, and the company is betting that higher tungsten prices will help turn that output into steady cash flow.
To fund the ramp-up, Almonty raised $700 million through convertible notes in June 2026. The financing gives the miner the capital it needs to bring Sangdong to full production while also supporting its other assets in Portugal, Spain, and the United States.
What Almonty Does — and Why Tungsten Matters
Tungsten is a hard, dense metal used in cutting tools, mining equipment, and military applications such as armor-piercing ammunition. It is classified as a critical mineral by many Western governments because of its strategic importance and the concentration of global supply in China, which accounts for more than 80% of production.
Almonty is a vertically integrated tungsten producer, meaning it controls everything from mining to processing. Its main product is tungsten concentrate, measured in metric ton units of tungsten trioxide (WO3/MTU). The company sells this concentrate through a mix of long-term contracts and spot-market deals, with prices typically tied to the benchmark ammonium paratungstate (APT) price.
In plain terms: Almonty’s revenue depends on how much tungsten it ships and the price it gets for each unit. Higher APT prices directly boost its top line, while production volumes determine how much of that price benefit flows through.
Sangdong: From Project to Business
Sangdong is Almonty’s flagship asset and one of the largest tungsten deposits outside China. The mine has been in development for years, and the March 2026 commissioning marks the point at which it begins producing concentrate for sale. The company has described this as moving Sangdong from “project” to “business.”
The ramp-up will take time. Mines rarely hit full capacity immediately; there are usually teething issues with equipment, ore grades, and processing efficiency. Investors will be watching quarterly production reports closely to see how quickly Sangdong reaches its nameplate capacity and whether costs stay under control.
The $700 million convertible note raise gives Almonty a financial cushion, but it also adds debt to the balance sheet. Convertible notes can be converted into equity, which could dilute existing shareholders if the stock price rises above the conversion price. For now, the company is focused on using that capital to build out infrastructure and hire staff.
What It Means for Investors
For everyday investors, Almonty’s story is about two things: commodity prices and execution risk. Tungsten prices have been trending higher in recent years, driven by supply constraints from China and rising demand from defense and industrial sectors in the West. Almonty is positioning itself as a Western, conflict-free supplier — a selling point that could command premium pricing from buyers looking to diversify away from Chinese sources.
However, the company is still in the early stages of production. The ramp-up at Sangdong will determine whether it can deliver on its promises. If output rises steadily and costs stay in line, the stock could benefit from both higher volumes and favorable pricing. If the mine struggles with technical issues or cost overruns, the opposite is true.
Investors should also consider the broader market backdrop. The widening US trade deficit and ongoing trade tensions could affect demand for industrial metals, including tungsten. On the other hand, defense spending in NATO countries is rising, which could support demand for tungsten in military applications.
Almonty’s convertible note structure adds another layer. If the stock performs well, conversion could dilute existing holders. If it underperforms, the debt still needs to be serviced. Investors should read the terms carefully.
What to Watch Next
The key metrics for Almonty going forward are quarterly production volumes, cash costs per MTU, and the APT benchmark price. Any news about new offtake agreements or contract renewals will also be important, as they lock in revenue visibility.
Almonty is not the only mining company making headlines. Minerals 260 recently boosted its gold resource estimate, and First Majestic Silver sold a mine in Mexico. But for investors focused on critical minerals, Almonty’s progress at Sangdong is one of the more significant developments in the tungsten space this year.
In short, Almonty has taken a big step forward by commissioning Sangdong. The next few quarters will show whether it can turn that step into a sustainable business.
