Greenland Mines engages Tetra Tech and GeoSim to produce an SEC-compliant resource update for its Sarfartoq rare earth project, advancing a key Western supply chain asset for neodymium and praseodymium.

Greenland Mines (NASDAQ: GRML) announced the engagement of Tetra Tech Canada Inc. and GeoSim Services Inc. to prepare an updated SEC S-K 1300-compliant mineral resource estimate for its Sarfartoq neodymium-praseodymium (Nd-Pr) rare earth project in southwest Greenland. The estimate, expected to be substantially completed this summer, will incorporate historical NI 43-101 resource work along with drilling and technical studies completed by Neo Performance Materials between 2023 and 2025. The update is intended to support an updated preliminary economic assessment and future development studies.
GeoSim, led by Ronald G. Simpson, P.Geo., has been appointed as the qualified person for the resource estimate, providing continuity from earlier Sarfartoq resource and economic studies completed in 2011 and 2012. Tetra Tech will provide engineering, mine planning and metallurgical support, including optimization studies evaluating open-pit, underground and hybrid development scenarios. Greenland Mines also reappointed WSP Danmark A/S to continue environmental baseline work at the project.
The Sarfartoq project is distinguished by a strong neodymium-praseodymium component, critical for permanent magnets used in electric vehicles and wind turbines, and holds strategic relevance to Western rare earth supply chains. The updated resource estimate will be a key step as Greenland Mines advances the project, which it believes could become a significant source of these magnet metals outside of China.
