Almonty Confirms Sangdong Mine Phase I Start, Eyes 1.2Mtpa Expansion
Almonty Industries has released an updated JORC technical report for its Sangdong Tungsten Mine, affirming Phase I production commencement in late 2025 and outlining plans for a fully permitted Phase II expansion to double throughput.
- Updated JORC report effective February 28, 2025
- Phase I production to start in second half of 2025 with 640,000 tpa throughput
- Phase II expansion planned to increase capacity to 1.2 million tpa, potentially starting in 2026
- Probable mineral reserves total 8.58 million tonnes at 0.42% WO3
- Robust economic analysis shows 14-year mine life with strong IRR and NPV
Updated JORC Report Validates Sangdong’s Progress
Almonty Industries Inc. has published an updated JORC-compliant technical report for its flagship Sangdong Tungsten Mine in South Korea, effective as of February 28, 2025. The report confirms no material changes from the previous 2020 technical disclosure, reinforcing the mine’s robust resource and reserve base and providing a comprehensive overview of development, processing, environmental, and economic parameters.
Phase I Production Set for Late 2025
The report details that Phase I of the mine and processing plant construction is on track to begin production in the second half of 2025. The initial ore throughput capacity is targeted at approximately 640,000 tonnes per annum, supported by a mining plan that leverages mechanized underground mining methods tailored to the deposit’s geometry. The mine’s probable mineral reserves stand at 8.58 million tonnes grading 0.42% tungsten trioxide (WO3), sufficient to sustain operations for about 14 years at this throughput.
Phase II Expansion Fully Permitted and Ready
Looking ahead, Almonty plans a Phase II expansion to increase throughput capacity to around 1.2 million tonnes per annum. This expansion is fully permitted under existing approvals and could be advanced as early as 2026, subject to positive operating results from Phase I and prevailing market conditions. The Phase II development would unlock economies of scale and enhance margins, with first ore production under this phase anticipated by 2027.
Comprehensive Technical and Economic Analysis
The updated report, authored by independent mining consultant Adam Wheeler, includes detailed geological, metallurgical, and mining method studies. The processing plant design incorporates crushing, grinding, and flotation circuits optimized for scheelite concentration, with metallurgical testwork supporting an 85% tungsten recovery and a concentrate grade of approximately 65% WO3.
Economic analysis projects a steady-state production of 640,000 tonnes per annum with a 14-year mine life, delivering an after-tax net present value (NPV) of US$271 million at a 5% discount rate and an internal rate of return (IRR) of 49.5%. Sensitivity analyses underscore the project’s resilience to commodity price fluctuations and operating cost variations.
Environmental and Social Commitments
Almonty has completed extensive environmental baseline studies and secured all necessary permits for construction and operation. The company emphasizes sustainable practices, including paste backfill to minimize surface tailings, water treatment facilities, and ongoing community engagement. Local support remains strong, with initiatives aimed at fostering regional development and employment.
Strategic Offtake and Market Position
Almonty has secured a 15-year offtake agreement with Global Tungsten & Powders Corp., providing pricing stability through a floor price mechanism while allowing participation in market upside. This agreement underpins the project’s commercial viability and aligns with Almonty’s strategy to establish Sangdong as a leading non-Chinese tungsten producer.
Bottom Line?
With Phase I production imminent and Phase II expansion poised, Sangdong is set to reinforce Almonty’s position in the global tungsten market, yet execution risks and market volatility remain watchpoints.
Questions in the middle?
- Will Phase II expansion proceed on schedule amid market uncertainties?
- How will tungsten price fluctuations impact Sangdong’s long-term economics?
- What operational challenges might arise during ramp-up of underground mechanized mining?
