SEOUL, South Korea: Almonty Industries (NASDAQ: ALM) has officially ended a three-decade silence in the mountains of Gangwon Province. The company confirmed Wednesday the successful completion of Phase 1 commissioning at its Sangdong tungsten mine, marking the return of one of the world’s most historically significant mineral assets to active production.
The restart isn’t just a corporate milestone. It is a massive geopolitical pivot.
For the last 30 years, the global tungsten market has been a story of Chinese dominance. That story changed this week. With Sangdong back online, Almonty is positioning itself to provide approximately 40% of the global tungsten demand outside of China. In a world currently obsessed with “de-risking” and “friend-shoring,” this isn’t just mining. It’s strategic defense.
The 30-Year Hiatus Ends
Sangdong was once the backbone of the South Korean economy. In the decades following the Korean War, this single mine accounted for more than 50% of the country’s export revenue. It was a titan. But the titan fell in 1994, a victim of a coordinated collapse in commodity prices as Chinese supply flooded the global market.
The mine didn’t run out of ore. It ran out of economic oxygen.
Almonty Industries acquired the project in 2015, betting that the world would eventually realize the danger of a single-source supply chain for critical minerals. Since then, the company has poured more than $100 million into redeveloping Sangdong as a modern, high-tech underground operation.
The result? A facility that looks nothing like the legacy site that shuttered in the early 90s. Phase 1 is now operational, featuring a processing plant designed to handle 640,000 tonnes of ore annually. This is expected to yield roughly 2,300 tonnes of tungsten concentrate per year.
That’s just the beginning.
Phase 2 and the 2027 Horizon
The strategic calculus here isn’t subtle. While Phase 1 is a victory, the real weight of Sangdong hits in 2027.
Almonty has already outlined a Phase 2 expansion intended to double processing capacity to 1.2 million tonnes of ore annually. By the time that expansion is fully integrated, Sangdong will be churning out approximately 4,600 tonnes of tungsten per year.
This timeline perfectly overlaps with a critical regulatory deadline in the United States. The Department of Defense has implemented a ban on tungsten imports from China for defense procurement, effective in 2027.
The timing isn’t a coincidence. It’s a lifeline for Western defense contractors who have been scrambling to find non-Chinese sources of a metal that is essential for everything from armor-piercing munitions to turbine blades and high-speed cutting tools.
The “Brutal” Geology of Sangdong
In mining, grade is king. Most global tungsten operations are struggling with declining grades, often hovering around 0.15% to 0.20% tungsten trioxide (WO3).
Sangdong is playing a different game.
The average grade at Sangdong is approximately 0.51% WO3. That’s roughly three times the global average. In terms of margins, that is a massive cushion. Higher grades mean less rock moved per pound of metal produced, lower energy costs, and a significantly smaller environmental footprint.
But the technical specs go deeper:
- Mine Life: Currently projected to exceed 45 years.
- Development: Over four kilometers of new underground tunnels already completed.
- Monitoring: Advanced real-time operational systems that would have been science fiction when the mine closed in 1994.
This isn’t just a restart of an old mine; it’s the birth of a top-tier global asset. As noted in the Skillings Mining Intelligence report from March 16, 2026, the industry is moving toward a “Critical Minerals Corridor” where high-grade, politically stable assets are the only ones that matter to institutional capital.
Geopolitical Leverage: Breaking the Stranglehold
China currently controls over 80% of global tungsten production. That is a stranglehold.
We’ve seen this script before with rare earths and lithium. When one nation controls the valves, the rest of the world waits in line. Tungsten, however, is unique because of its industrial density and military applications. You cannot build a modern military: or a high-end semiconductor fabrication plant: without it.
The restart of Sangdong represents the first genuine challenge to that monopoly in decades. By providing a massive, high-grade source of supply in a Tier-1 jurisdiction like South Korea, Almonty is effectively de-risking the entire Western supply chain.
This follows a broader trend of Western nations pouring capital into alternative mineral hubs to counter the Chinese “chokehold,” a topic we explored recently regarding U.S. investment in Latin American minerals. South Korea is now the front line of this effort in East Asia.
The Semiconductor Connection
While defense often gets the headlines, the “shiny AI revolution” is equally dependent on what comes out of the ground at Sangdong. Tungsten is a critical component in the manufacturing of advanced semiconductors.
South Korea is home to the world’s leading chipmakers. Historically, these companies have relied on imported tungsten. By having a domestic supply of 0.51% grade ore literally in their backyard, South Korean industry gains a massive competitive advantage. It’s a closed-loop system that protects their most valuable export industry from global supply shocks.
This intersection of mining and high-tech manufacturing is the new blueprint for industrial stability. You can’t have the “Green Transition” or the “AI Boom” without the “Old Economy” digging holes in the ground. That’s a reality some policymakers are finally starting to grasp, as seen in the discussions surrounding the Per Geijer rare earths discovery.
Risk Factors: The Reality Check
Despite the celebratory tone of the commissioning, Sangdong is not without its risks. No project of this scale is.
- Phase 2 Execution: Doubling capacity by 2027 is an ambitious engineering feat. Any delays in equipment delivery or underground development could push that 4,600-tonne target further out.
- Labor Shortages: The mining industry globally is facing a massive talent drain. Finding skilled underground miners and metallurgical engineers in a high-tech economy like South Korea is an expensive challenge.
- Price Volatility: While Almonty has high grades to protect its margins, a sharp downturn in global tungsten prices could still pinch cash flows during the capital-intensive Phase 2 build-out.
The Bottom Line
The restart of the Sangdong mine is a “chickens-coming-home-to-roost” moment for global mineral policy. For thirty years, the West was content to let China handle the “dirty work” of tungsten mining. That complacency ended the moment supply chains became weapons of economic warfare.
Almonty Industries has spent a decade preparing for this exact moment. With Phase 1 now active and Phase 2 on the horizon, they aren’t just selling a commodity; they are selling security.
As we look toward 2027, the importance of Sangdong will only grow. In a market where 80% of the supply is controlled by a single geopolitical rival, being the guy with the other 20% isn’t just a good business move. It’s an essential one.
There simply isn’t enough high-grade tungsten to go around. Almonty just made sure that, for the first time in 30 years, China isn’t the only one holding the keys.
