Almonty Industries has strengthened the commercial foundation of its Sangdong tungsten project in South Korea by extending a long-term concentrate supply agreement with Global Tungsten & Powders, a subsidiary of Austria’s Plansee Group. The revised agreement extends the contract from 15 to 21 years and increases the amount of tungsten concentrate covered by the deal by 40 per cent, giving Almonty substantially greater revenue visibility as Sangdong moves into production.
Processing at Sangdong began on 1 July, marking a major transition for a project that is strategically important to the global tungsten market because of the mineral’s critical role in industrial manufacturing, defence and advanced technology.
The amended contract applies to Phase I of Sangdong and covers approximately 4.41 million metric tonne units (MTU) of tungsten concentrate, compared with 3.15 million MTU under the previous agreement. Once production reaches its targeted operating level, minimum deliveries are expected to reach 210,000 MTU a year. Pricing terms have also improved. Almonty said the revised structure increases pricing across the contracted volumes by approximately 6.3 per cent, strengthening the economics of the project at a time when non-Chinese tungsten supply is attracting increasing attention.
Global Tungsten & Powders to Take Most of Phase I Output
Global Tungsten & Powders is expected to purchase roughly 90 per cent of Sangdong’s Phase I tungsten concentrate production. The buyer, based in Pennsylvania, produces tungsten powders and related products for industrial and defence applications in the United States. That makes the agreement more strategically significant than a conventional mining offtake, particularly as China has tightened controls over exports of several critical minerals and tungsten-related products.
For Almonty, the contract provides a substantial degree of market certainty during the crucial ramp-up period. Instead of entering full production without a defined customer base, Sangdong will have most of its initial output covered by a long-duration agreement with an established downstream processor. The arrangement also strengthens the project’s position within efforts to diversify tungsten supply away from China.
Revenue Potential Rises as Tungsten Prices Strengthen
Almonty estimates that the amended pricing arrangement could generate at least US$30 million of additional annual revenue at current ammonium paratungstate prices. The company has also placed a headline value of approximately US$490 million on the expanded agreement at current prices, while separately estimating around US$630 million of incremental revenue over the amended contract period.
Those figures should not be interpreted as guaranteed future revenue. They appear to reflect different calculation assumptions, and actual cash generation will depend on production volumes, the pace of the Sangdong ramp-up, tungsten prices, concentrate specifications and the contract’s pricing formula.
Nevertheless, the significance of the agreement lies in the amount of Sangdong production that has effectively been assigned a commercial destination. Long-term offtake coverage can also improve the project’s financing profile because lenders and investors have greater visibility over future sales. For a newly commissioned tungsten operation, that can be nearly as important as headline production capacity.
Phase II Remains Outside the Agreement
The agreement applies only to Phase I production. Almonty has retained additional growth potential through Phase II, which could approximately double Sangdong’s processing capacity. Future output from that expansion has not been included in the amended Global Tungsten & Powders contract. The company also retains exposure to its Panasqueira tungsten mine in Portugal and its planned tungsten development activities in the United States.
That creates an important distinction for investors. Sangdong’s first phase now has substantial commercial coverage, while future growth remains dependent on additional financing, construction decisions and separate customer commitments. If Phase II proceeds successfully, Almonty would have the opportunity to negotiate additional offtake arrangements under potentially different market conditions.
Financing Risk Gives Way to Operational Execution
Sangdong has already secured significant project financing, including a US$75.1 million senior facility associated with KfW IPEX-Bank and Austrian export-credit support. Almonty also entered 2026 with increased liquidity following capital raisings on Nasdaq.
As a result, the company’s immediate challenge has shifted. The central question is no longer simply whether Sangdong can secure development capital, but whether the operation can consistently deliver the production, recovery rates and concentrate quality assumed in its commercial agreements. Commissioning is often one of the most important risk periods for a mining project. Equipment performance, plant availability, metallurgical recovery and concentrate specifications can all affect the volume and value of material available for delivery. For Almonty, successful ramp-up will therefore determine how quickly the newly expanded offtake agreement translates into actual revenue and cash flow.
Tungsten Supply Chain Gains Strategic Importance
Tungsten is used in applications ranging from hard metals and cutting tools to aerospace, electronics and defence equipment. Its combination of hardness, density and high-temperature performance makes substitution difficult in several industrial applications. The heavy concentration of global tungsten supply in China has consequently increased the strategic value of projects capable of producing outside the country.
Sangdong is particularly relevant because it offers a potential large-scale source of tungsten concentrate in South Korea, while its downstream customer has direct exposure to the US industrial and defence supply chain. That gives the project significance beyond its own financial returns. It forms part of a broader effort to build alternative critical-minerals supply routes connecting non-Chinese mining, processing and manufacturing capacity.
Strong Offtake Brings Concentration Risk
The expanded contract also introduces a less obvious risk. With Global Tungsten & Powders expected to take around 90 per cent of Phase I production, Sangdong has considerable customer concentration. The arrangement improves bankability and revenue visibility, but it also makes the project’s commercial performance heavily dependent on one major buyer and one pricing mechanism.
Any disruption affecting the buyer, contract terms or physical delivery chain could therefore have a disproportionately large impact on Phase I sales. The same concentration also places greater importance on Almonty’s ability to meet contractual specifications and maintain reliable production from a newly commissioned facility.
Sangdong Becomes One of the Best-Covered Non-Chinese Tungsten Projects
The combination of project financing, commissioning and expanded long-term offtake has moved Sangdong into a different stage of development. Almonty now has a substantial portion of its initial production commercially committed, while the revised agreement improves pricing and extends customer visibility well into the future.
The remaining test is operational execution. If Sangdong achieves a stable ramp-up and delivers consistent tungsten concentrate at the expected quality, the project could become one of the more commercially secured non-Chinese tungsten supply sources in the global market. For investors, the focus is consequently shifting from whether Sangdong can reach production to how efficiently Almonty can convert its newly contracted tonnes into cash flow, margins and long-term growth.
