en.Wedoany.com Reported - Dalaroo Metals Ltd has transformed the Blue Lagoon project in southern Greenland from an early-stage exploration concept into a defined regional rare earth element system, following the completion of its largest field program to date.

The 2026 campaign, which combined geological and structural mapping, surface geochemistry, ground-penetrating radar (GPR), bathymetry, and lagoon and offshore sediment sampling at the 100%-owned project, identified four new rare earth element targets and laid the groundwork for a comprehensive three-dimensional geological model to guide future drilling.

More than 200 geological, rock chip, stream sediment, and surface sediment samples have been collected and are being sent to ALS Laboratories in Perth for multi-element analysis, mineralogical assessment, and preliminary metallurgical testing.

Regional mapping has identified the Qilluakitsoq, Quernertullip, Taseq, and Blue Lagoon South prospects, substantially expanding Dalaroo's exploration pipeline. Blue Lagoon South, located approximately one kilometer south of the flagship prospect, adds about 34 square kilometers to the prospective area and adjoins Amaroq Minerals' Ilua rare earth discovery, where drilling is testing a mineralized system with a strike length of approximately five kilometers.

Mapping confirmed that Blue Lagoon South shares similar geological units with the main project, including felsic alteration, quartz syenite, alkali granite, pegmatite, and aplite intrusions. Dalaroo stated that the favorable geology extends into its tenure, strengthening the rationale for follow-up exploration. Qilluakitsoq contains a layered alkaline intrusive complex, rapakivi granite, and magnetic heavy mineral sands, potentially representing a second mineral sand system in the company's Greenland portfolio.

Quernertullip consists of a ring-shaped alkaline intrusive complex comprising syenite, alkali granite, and altered contact zones. Taseq contains alkali granite, metasomatic alteration, and a major shear zone, and is considered prospective for structurally controlled rare earth mineralization.

The program also advanced Dalaroo's source-to-sink exploration model, under which rare earth-bearing minerals weather from surrounding alkali granites and pegmatites, are transported through drainage systems, and deposited in the Blue Lagoon basin. Mapping identified several catchment areas with lengths of approximately 1.3 to 2.4 kilometers, significantly increasing the potential volume of source rock delivering material to the lagoon. The company believes the combination of multiple source areas, extensive drainage pathways, and the lagoon depositional environment may create a favorable zone for heavy mineral accumulation.

Ground-penetrating radar surveys were completed over five priority beach systems, along with full bathymetric coverage of the lagoon, aimed at mapping sediment thickness, basin geometry, paleochannels, and potential depositional centers in preparation for drill targeting.

Dalaroo CEO John Morgan described the field season as transformative, stating that the company now has a clearer understanding of the geological system that generated the mineralized sediments leading to the 2025 discovery. The identification of multiple alkali granite and pegmatite phases, extensive drainage systems, and interpreted eudialyte-like mineral occurrences has increased confidence that Blue Lagoon represents a large, fertile rare earth system. The visual identification of potential eudialyte-like minerals remains preliminary and requires confirmation through laboratory analysis.

Dalaroo will now interpret the ground-penetrating radar and bathymetry datasets and integrate geological, structural, geochemical, mineralogical, and sediment information into a three-dimensional project model. Assay results from the 200 surface samples, along with lagoon and offshore sediment analysis and mineralogical confirmation work, are expected within two to three months. Preliminary metallurgical testing and follow-up exploration planning will also support the generation of priority drill targets.
