RareX Limited (ASX: REE, RareX or the Company) provides the following additional information with regard to the visual observations of mineralisation reported in the announcement dated 25 May 2022.
Cautionary note: The Company stresses that the reported visually estimated percentages in the table above relate specifically to the abundance of rare earths mineralisation logged in the drill core and is not an estimated grade for the interval. In relation to the disclosure of visual results, the Company cautions that visual estimates of mineral abundance should never be considered a proxy or substitute for a laboratory analysis. Assay results are required to determine the widths and grade of the visual mineralisation in preliminary geological logging. The Company will update the market when laboratory results become available.
RareX has a Niton XRF on site that has been calibrated to Cummins Range mineralisation. The XRF analyses for 43 elements including Cerium, Lanthanum, Praseodymium, Neodymium, yttrium, Niobium and Phosphorus. The XRF is used as a tool to indicate whether a zone is mineralised, however it is not an accurate indicator of grade. With the XRF results, rock type and visual confirmation of mineralisation, the RareX geologist can assess whether an interval is mineralised.
This announcement has been authorised by the Managing Director of RareX Limited.

Dalaroo Prepares Maiden Work Program for Blue Lagoon Zirconium, Niobium and Rare Earth Project in Greenland
Highlights
- Dalaroo has advanced planning for upcoming maiden field season at the Blue Lagoon Zr- Nb-REE project, Greenland. Field work will be conducted towards the end of June 2025.
- A program of auger drilling, stream sediment and soil sampling and reconnaissance mapping and sampling has been designed to follow up on historical highly anomalous values returned in a regional stream sediment program undertaken by the Greenland and Denmark Geological Society (‘GEUS”) for uranium in 1979 (refer to ASX release 20th Feb, 2025).
- No follow-up work on these results has ever been reported on the tenement.
- Dalaroo has secured the services of highly respected and experienced Greenland geologist Ole Christiansen, who has been instrumental in the modern development of metals in Greenland, including Critical Metal’s (NASDAQ: CRML Critical Metals Corp) Tanbreez project.
- The Blue Lagoon Project has similar geochemical anomalous footprint to the Kvanefjeld (ASX: ETM Energy Transition Metals) and Kringlerne/Tanbreez multi-element deposits in South Greenland, showing enrichment in critical minerals and high value LREE elements from regional stream sediment sampling. These projects are all hosted within the south- west north-east trending Gadar alkaline intrusive province where Blue Lagoon Is also located.
- US administration has continued to show considerable interest in Greenland, highlighting the importance Greenland has for critical metals and their ownership.
- Auger drilling to sample alluvial and colluvial material will form a key part of the program. In situ weathering of the alkaline granite might provide bulk tonnage options from beach- like deposits, providing potential low-cost options for mining and separation. Characterising these deposits geochemically is the first step of the evaluation of this potential.
Dalaroo Metals MD & CEO, Mike Brown commented“We are excited to have advanced a maiden field program at Blue Lagoon, and also secured the services of renowned Greenland geologist Ole Chistiansen. Auger drilling of weathered granite areas will be a key objective of the program. Stream, soil and rock chip sampling and prospecting over the tenement will complete the program. This should provide the first insight into the potential of the project to host heavy mineral sands type deposits of strategic metals and REEs. Placer deposits have obvious benefits on the cost of mining. With the Project being located on the coast with ice free water we are looking forward to getting onto the ground to commence exploration activities in June and report results when in hand.”

The large and highly anomalous zirconium, niobium and REE geochemical anomalies over the Project area provides a compelling multi-commodity exploration target. The Vendor has identified the presence of potential bulk tonnage ‘placer’ type deposits from in-situ weathered granite. This is characterised by highly anomalous LREE and Nb signature, which is very similar to the geochemical signature that coincides with 3 other significant REE deposits in South Greenland associated with Gadar Block alkaline intrusives. The Company is looking forward to reporting the results of the work program as they come to hand.

High-Grade Discoveries Enhance Scale of Pelé Project
New discovery of high-grade REE-Nb-Sc-Ta-U mineralisation
- High-grade diamond drill results at Pelé Target 1 returned assays of up to 13.5% TREO:
- NdPr: 23,217 ppm | DyTb: 938 ppm | Nb2O5: 5,011 ppm | Sc2O3: 381 ppm | Ta₂O₅: 248 ppm | U3O8: 1,100 ppm
- High-grade REE-Nb-Sc-Ta-U from shallow depths (~20 m) extending to vertical depths of ~70 m
- Drillhole TG1DD0004 returned 29.8 m of a cumulative downhole mineralisation, including 15.3 m at 9.1% TREO from 25.6 m depth, with grades of:
- NdPr: 15,617 ppm | DyTb: 692 ppm | Nb₂O₅: 1,861 ppm | Sc₂O₃: 231 ppm | Ta₂O₅: 94 ppm | U₃O₈: 754 ppm
- Auger drilling continues to discover extensive, near-surface horizons of high-grade monazite sands, with grades of up to 7.9% TREO and assays of up to 11,681ppm NdPr and 580 ppm DyTb
Pelé Target 1 discoveries extend high-grade mineralised trendline to 10 km
- Pelé is confirmed as a major district-scale rare earth exploration project located ~60 km southwest of BRE's Monte Alto project in Bahia, Brazil, and covers an exploration area over 60 times larger than Monte Alto
- Recent exploration has focussed primarily on Pelé Target 1 – one of five large exploration target areas within the larger Pelé Project area – delivering new discoveries of high-grade rare earth outcrops with grades of up to 17.7% TREO and high-grade monazite sands with grades of up to 8.5% TREO
- New outcrop discoveries of high-grade REE-Nb-Sc-Ta-U mineralisation significantly extend the mineralised strike at Pelé Target 1 to over 10 km
- Brazilian Rare Earths now controls three major confirmed projects - Monte Alto, Sulista and Pelé – each demonstrating significant diamond drill intersections of high-grade REE-Nb-Sc-Ta-U mineralisation
Figure 1: Pelé project location and relative size 1
The Pelé Project is hosted within the Volta do Rio Plutonic Suite, a large-scale magmatic system that extends over 180 km in Bahia, Brazil. Brazilian Rare Earths has confirmed the exploration potential of the province with multiple discoveries of ultra-high-grade mineralisation, including rare earth elements (REE), niobium (Nb), scandium (Sc), tantalum (Ta), and uranium (U).
Pelé Target 1 has the largest expanse of weathered REE-Nb-Sc-U outcrops discovered since exploration commenced at the Rocha da Rocha rare earth province. New geological mapping, 75 line-km of ground gamma stations and 162 new outcrop samples highlights that REE-Nb-Sc-Ta-U mineralisation repeats along eastern and western limbs of a regional structural fold that now extends over 10 km at the project.
Successful diamond drilling at Pelé Target 1
The new drilling results are from 10 diamond core holes totalling 901 metres and 100 auger drill holes totalling 1,095 metres. Assays are pending for a further 19 auger holes totalling 243 metres.
High-grade, hard rock REE-Nb-Sc-Ta-U mineralisation was intersected from shallow depths with assay grades of up to 13.5% TREO. High grades of neodymium and praseodymium were recorded, with grades up to 23,217 ppm NdPr, as well as high grades of dysprosium and terbium of up to 938 ppm DyTb.

Dalaroo Secures Option on Blue Lagoon Zirconium, Niobium and Rare Earth Project in Greenland
Highlights
- Binding Heads of Agreement executed for an Option to acquire 100% of Blue Lagoon Zirconium-Niobium-Rare Earth Element (REE) Project, (MEL 2022-07), located in the Gadar Province of Greenland.
- The USGS reports Greenland has the third highest reserves of REE in the western world, following US and Australia respectively, which has significance given current geopolitical dynamics and security of supply chain concerns.
- President Trump’s recent interest in Greenland as a source of critical resources and its strategic location highlights the growing importance Greenland has for critical metals and their ownership.
- The Project has been historically sampled as part of a regional stream sediment exploration undertaken by the Greenland and Denmark Geological Society (‘GEUS”) for uranium in 1979. Dalaroo is planning a program of systematic exploration to seek to report the historical results on the Project in accordance with the JORC Code 2012.
- Project has similar geochemical anomaly footprint to the Kvanefjeld (ASX: ETM Energy Transition Metals) and Kringlerne/Tanbreez (NASDAQ: CRML Critical Metals Corp) multi- element deposits in South Greenland, showing enrichment in critical minerals and high value LREE elements from regional stream sediment sampling:
- Up to 0.93% Zirconium (Zr)
- Up to 320 ppm in Niobium (Nb)
- Up to 520 ppm in Neodymium (Nd)
- Sampling has not returned any elevated radioactive elements, which is significant given the current Greenland Government ban on any activities related to mining if uranium concentrations are over 100ppm.
- Project sits on the westernmost part of the highly prospective Gadar Block alkaline intrusives belt in SW Greenland. This belt hosts significant advanced critical metals-REE deposits.
- Project area contains potential bulk tonnage options from beach-like deposits of weathered granitic rock, providing potential low-cost options for separation and the planned focus for preliminary work.
Dalaroo MD & CEO, Mike Brown commented “We are very excited to have secured this Option on the Blue Lagoon REE-Nb-Zr Project in Southwest Greenland. Regional stream sampling has indicated significant LREE anomalies and other critical metals that have both similar tenor to the geochemical footprint and geological setting of three other REE deposits in South Greenland. We see this as a strategic play on two levels; firstly, exposure to high demand commodities such as REE, niobium and zirconium and secondly, exposure to a highly prospective and unexplored jurisdiction that is getting significant attention with respect to the vital role Greenland could play in providing critical metals in the future. With the Project being located on the coast with ice free water we are looking forward to getting onto the ground to commence exploration activities.”
