Greenland Mines Sarfartoq Initial Assessment Values Rare Earth Project at Up to $2.05 Billion

Greenland Mines (NASDAQ:GRML) has released an independent Sarfartoq Initial Assessment that values its Greenland rare earth project at up to $2.05 billion on a pre-tax NPV basis under a high-case scenario, with a 118.6% internal rate of return and a planned nine-year mine life.

Key Investor Takeaways

• The Sarfartoq Initial Assessment estimates a high-case pre-tax NPV8 of approximately $2.05 billion and IRR of 118.6% when Indicated and Inferred Mineral Resources are included.
• Using Indicated resources while excluding Inferred resources produces a high-case pre-tax NPV8 of $1.49 billion and IRR of 92.7%.
• Greenland Mines (NASDAQ:GRML) outlines a nine-year operation processing 12.2 million tons at approximately 1.4 million tons annually.
• At 2025 consumption levels, management estimates planned annual NdPr oxide production could equal approximately 34% of NdPr oxide refined outside China during each scheduled operating year.
• The economic figures are preliminary and the $2.05 billion valuation represents a high case incorporating more favorable pricing, operating cost and capital cost assumptions than the base case.

Why GRML Stock Is in Focus

The independent Initial Assessment provides investors with the first economic framework for developing Sarfartoq using a combined open-pit and underground mining scenario.

The high case generates a pre-tax NPV8 of approximately $2.05 billion and a 118.6% IRR using both Indicated and Inferred Mineral Resources. The scenario assumes a basket price 15% above the base case, operating costs 15% below the base case and capital costs 20% below the base case.

Using Indicated resources while excluding Inferred resources reduces the high-case NPV8 to $1.49 billion and the IRR to 92.7%.

The underlying resource consists of 6.9 million tons of Indicated Mineral Resources grading 1.60% total rare earth oxides and 5.3 million tons of Inferred Mineral Resources grading 0.96% TREO.

The proposed operation would process 12.2 million tons over nine years at a delivered head grade of 1.32% TREO. Metallurgical testing conducted by SGS Canada in 2026 produced flotation concentrates of approximately 8.25% TREO at a design recovery of 63.6%.

Why This Matters for Investors

The Initial Assessment gives Sarfartoq a quantified development case as Greenland Mines works toward a Pre-Feasibility Study.

Its NdPr concentration is strategically relevant to the project’s positioning. Neodymium and praseodymium account for approximately 84% of the in-concentrate basket value, focusing the project on rare earth elements used in high-performance magnets.

Management estimates that planned annual production from the ST1 deposit alone could represent approximately 34% of all NdPr oxide refined outside China at 2025 consumption levels. If the project advances as proposed, that scale could make Sarfartoq relevant to Western efforts to develop alternative rare earth supply chains.

The potential relationship with Neo Performance Materials (TSX:NEO) adds another strategic element. Subject to the transaction described by Greenland Mines, Neo is expected to become a shareholder while retaining non-binding offtake rights covering up to 60% of future Sarfartoq concentrate production for processing at its Silmet facility in Estonia.

Investors should nevertheless distinguish the Initial Assessment economics from an operating mine valuation. The headline $2.05 billion NPV comes from the high-case assumptions and includes Inferred Mineral Resources. Greenland Mines still plans additional drilling, metallurgical work, engineering and environmental studies before advancing toward a Pre-Feasibility Study.

What to Watch Next

Greenland Mines plans targeted infill drilling to upgrade Inferred Mineral Resources, pilot-scale metallurgical testing and further mine engineering work as it advances Sarfartoq toward a Pre-Feasibility Study.

Environmental baseline investigations are scheduled to continue in September 2026, while the technical team also plans to return to the project for district-scale exploration.

Exploration outside ST1 could become another catalyst. The deposit covers well under 1% of the 191-square-kilometer licence, while five other known rare earth occurrences along the approximately 32-kilometer outer ring structure remain largely untested.
