What the Merino assay results mean

The latest assay results from the Merino prospect add useful geological evidence to Alba’s work at the Motzfeldt Project in South Greenland.

The RNS reported highest grades of 1.36% TREO, 0.73% Nb₂O₅ and 2.3% ZrO₂ from surface rock samples collected during the 2025 field season.

What stands out is not only the grade, but the composition of the mineralised structures. The elements present at Merino, including Nb, REE, Zr, Fe and F, are the same elements interpreted as being mobilised at Aries from the pyrochlore microsyenite in Rooks et al. (2026).

This supports Alba’s current Motzfeldt model. The working interpretation is that these mobilised elements rose higher into the roof zone, with Merino representing this higher-level expression of the system.

That matters because the model predicts potential Aries-type mineralisation beneath Merino.

The results strengthen the view that hydrothermal fluids play a key role in the critical mineral distribution at Motzfeldt, and provide the first reported percentage-level TREO result from Merino in around 20 years.
