Key Takeaways:
Greenland Mines' Sarfartoq rare earth project carries a pre-tax NPV of up to US$2.05 billion at 118.6% IRR, per a maiden S-K 1300 study released Aug. 25.
"This Initial Assessment quantifies a de-risked and highly economic development case that puts this deposit in the top-tier of North American, European and western-world oriented upstream rare-earth magnet assets," Bo Møller Stensgaard, president of Greenland Mines, said.
The high case combines a basket price 15 percent above base-case assumptions, operating costs 15 percent below base case and capital costs 20 percent below base case, with physicals, mine schedule and metallurgical recovery held identically. Excluding Inferred resources, the project carries a pre-tax NPV of US$1.49 billion at a 92.7% IRR. The study, with an effective date of July 31, 2026, is based on a hybrid open-pit and underground Mineral Resource Estimate of 6.9 million tonnes of Indicated resources at 1.60 percent TREO and 5.3 million tonnes of Inferred resources at 0.96 percent TREO, released Aug. 24.
At 2025 consumption levels, the NdPr oxide Sarfartoq is expected to produce from ST1 alone would represent approximately 34 percent of all NdPr oxide refined outside China for each of the project's nine scheduled operating years. Greenland Mines plans targeted infill drilling, pilot-scale metallurgical test work and continued environmental baseline studies led by WSP Denmark, advancing toward a Pre-Feasibility Study.
Beyond ST1: Five Additional REE Occurrences
The Initial Assessment covers only the ST1 deposit, which sits within the outer ring structure around the Sarfartoq carbonatite complex — a structure that circles roughly 32 kilometers within the 191-square-kilometer exploration license (MEL 2020-32). Well under 1 percent of the land package has been explored in detail, according to the company.
Five other known rare earth occurrences — ST40, ST19, ST24, ST31 and ST43 — have seen very limited exploration drilling but returned significant results. ST40, lying on the same outer ring structure 4 kilometers from ST1, shows historical sampling indicating it is more neodymium-enriched than ST1 itself. The company plans to deploy high-resolution, low-level drone-based magnetic surveys in September 2026 to prioritize additional targets across the license ahead of ground-based follow-up.
Neo Performance Materials offtake at 60%
The project's scale is significant in the context of Western rare earth supply. Neo Performance Materials Inc. (TSX: NEO) is set to become a strategic Greenland Mines shareholder and retain offtake rights on up to 60 percent of future Sarfartoq ore or mineral concentrate production, subject to closing of the previously announced acquisition of Neo North Star Resources Inc.
Neodymium and praseodymium are the two elements every high-performance permanent magnet depends on, spanning EV traction motors, wind turbine generators and defense applications. The Sarfartoq project's planned output would supply roughly a third of all NdPr oxide refined outside China each year of its operating life, according to the company.
