Highlights

Eclipse reported a 208Mt Gronnedal rare earth Mineral Resource Estimate in April 2026.
The estimate included approximately 6Mt Indicated and 202Mt Inferred material.
October 2026 announcements reported diamond drilling underway at Gronnedal, including a two-rig update.
The company also reported a maiden Ivigtut hafnium-bearing resource in July 2026.

Eclipse Metals Ltd (ASX:EPM) is an Australian mineral exploration company with projects in Greenland and Australia, including rare earth and critical mineral prospects at Gronnedal and Ivigtut. Eclipse Metals (ASX:EPM) shares closed at AUD 0.01 on 10 November 2026. During 2026, its Greenland work advanced through updated mineral resource estimates, metallurgical investigations and a new diamond drilling campaign. These activities remain exploration and assessment work rather than commercial mineral production.

Gronnedal Resource Expands in April 2026

In April 2026, Eclipse Metals (ASX:EPM) announced a Gronnedal rare earth Mineral Resource Estimate of 208 million tonnes grading 7,239 parts per million total rare earth oxides (TREO), using a 2,000ppm TREO cut-off. The estimate comprised approximately 6Mt in the Indicated category and 202Mt in the Inferred category.

The company reported approximately 1.5Mt of contained TREO in the updated estimate. That figure describes material estimated within the deposit, not recoverable product, annual output or projected revenue. The April release also described feasibility-related work, but it did not establish that commercial feasibility had been demonstrated.

October Drilling and Mineral Processing Work

In September 2026, Eclipse Metals (ASX:EPM) outlined plans for diamond drilling intended to advance the Gronnedal resource. Its 14 October announcement subsequently reported that diamond drilling had commenced, followed by a 20 October update describing two-rig drilling underway. Results from new holes must be assessed before conclusions can be drawn about additional mineralisation.

A September 2026 announcement also addressed mineralogical testwork and a potential beneficiation pathway for neodymium and praseodymium-bearing minerals. For Eclipse Metals (ASX:EPM), the relationship between mineral composition, recoverability and processing costs remains an important technical question as the Gronnedal programme proceeds.

Ivigtut and Other Exploration Interests

The company reported a maiden Inferred Mineral Resource for the Ivigtut area in July 2026. The estimate covered hafnium-bearing and associated polymetallic mineralisation, expanding the technical information available for assessment of the Greenland project. An Inferred estimate is preliminary in confidence and should not be interpreted as a Mining plan or evidence of an operating business.

In August 2026, Eclipse Metals (ASX:EPM) announced that it had regained full control of its Liverpool uranium project in Australia. This gives the company another exploration interest alongside its Greenland activities, but it does not establish a near-term production schedule. Management must decide how to allocate technical resources and funding between programmes with different geological and regulatory requirements.

Funding, Permitting and Execution Risks

Exploration expenditure can precede any commercial cash inflows by several years. Eclipse Metals (ASX:EPM) therefore faces funding requirements for drilling, laboratory work, studies and corporate costs. Additional financing may be necessary as programmes progress, potentially affecting existing shareholders. Permitting, environmental assessment, infrastructure planning and Greenland operating conditions are also relevant to any eventual development pathway.

The key near-term distinction is between activities completed and outcomes still being evaluated. Drilling commenced in October 2026, while assay interpretation, possible resource revisions and further processing assessments depend on subsequent work. Investors assessing the company should not treat reported resource tonnage as equivalent to saleable production or cash generation.

Key Insights

Eclipse Metals (ASX:EPM) entered late 2026 with a larger Gronnedal resource estimate and active drilling. Geological confidence, processing performance, permitting and financing remain central to determining whether its exploration Assets can progress toward development.
