Dalaroo Metals has completed the biggest-ever field program at its Blue Lagoon rare earths project in Greenland, describing the work as "transformational". The company has defined a regional-scale system, identified four new targets, and expanded its footprint by 34 square kilometres adjacent to Amaroq Minerals' major Ilua rare earths discovery. Over 200 geological samples are now heading for assay.
Dalaroo Metals says it has completed a transformational field program at its Blue Lagoon rare earths project in southern Greenland, evolving the asset from an early-stage concept into a well-defined regional system with a swag of new targets.
The company’s biggest-ever exploration campaign at the project has identified four new rare earth element (REE) prospects, expanded its ground holding and significantly bolstered its “source-to-sink” exploration model.
More than 200 geological, rock chip, stream sediment and surface samples have been collected and are now on their way to a Perth laboratory for analysis.
The program was designed to test Dalaroo’s theory that REE-bearing heavy minerals are eroding from fertile intrusive source rocks in the area and being concentrated by natural processes in the Blue Lagoon basin.
The company says mapping has now identified multiple well-developed drainage catchments, up to 2.4 kilometres long, feeding the lagoon from REE-prospective alkaline granites and pegmatite-rich rocks.
Perhaps the most intriguing development is the definition of the new “Blue Lagoon South” target, which expands the company’s prospective footprint by 34 square kilometres.
Notably, the new ground sits right next to neighbour Amaroq Minerals’ massive Ilua REE discovery, where an extensive drilling program is currently testing a mineralised system over an impressive 5km of strike.
Dalaroo says its initial field mapping at Blue Lagoon South has confirmed the presence of similar rocks to those at the main Blue Lagoon prospect, including extensive fenite alteration, quartz syenites and pink alkaline granites, all of which are recognised as prime host rocks for REE mineralisation.
Dalaroo Metals chief executive officer John Morgan said: “The completion of our 2026 field program marks a significant milestone in the evolution of the Blue Lagoon Project. What began as a highly encouraging heavy minerals discovery in 2025 has now evolved into a much clearer understanding of the geological system responsible for generating those mineralised sediments.”
In addition to Blue Lagoon South, the company has also banged metaphorical flags in the ground at three other new prospects to the east, dubbed Qilluakitsoq, Quernertullip and Taseq.
The Qilluakitsoq prospect has been identified as a layered alkaline intrusive complex, with field mapping already pinpointing a significant circular Rapakivi Granite unit. Rapakivi granites are recognised globally as highly crystallised intrusive rocks capable of hosting elevated concentrations of rare earths.
The Quernertullip prospect comprises a well-defined, ring-shaped alkaline intrusive complex considered prospective for REE’s. In contrast, the Taseq prospect is an alkaline granite intrusive complex displaying widespread geological features, also considered favourable for REE mineralisation.
The comprehensive field campaign included detailed geological and structural mapping, which the company says has defined a complex, multi-phase alkaline intrusive system.
During the mapping, Dalaroo’s geos identified multiple occurrences of red-coloured minerals visually interpreted as possible eudialyte-like phases, a mineral group known to host rare earths, which will need lab confirmation.
A suite of geophysical and sampling work was also completed to support future drill targeting, including ground-penetrating radar, bathymetric surveys and Van Veen sediment grab sampling.
The project sits in the Gardar Alkaline Province of southern Greenland. This region is rapidly emerging as a globally important jurisdiction for rare earths and critical minerals as Western nations look to diversify supply chains.
With field activities now complete, the company’s focus is shifting to the lab, where the 200 samples will undergo assay, mineralogical and preliminary metallurgical studies.
The results are expected to take two to three months. They will be integrated into Dalaroo’s geological model to prioritise targets for the next phase of exploration, possibly with the drill bit.
Dalaroo headed to the icy shores of Greenland in 2026 with a clear mission to uncover the source of the rare earth mineralisation. With the field campaign now complete, four new targets in the bag and the all-important discovery of REE-bearing rocks right where they should be, it appears this exciting 2025 surface discovery could have the potential to transform into a large-scale regional mineralised system.
