("NFM" or the "Company")

 

Sampling returns 10.61% TREO with 23.56% Nb2O5 and 15.67% Ta2O5 at Harts Range, NT

New Frontier Minerals Ltd ("New Frontier" or "the Company") (LSE and ASX: NFM) is pleased to report geochemical assay results from the Harts Range Project, located 140km north-east of Alice Springs in the Northern Territory, Australia.

Assay results from the April 2025 field programme have confirmed two new drill targets and identified promising new prospects - Paddington and Westminster, located approximately 200m and 450m west of the mineralised Bobs Prospect. These new prospects, along with the mineralised prospects Cusp and Bobs, are associated in proximity to an east-west trending structural corridor now extending over 2 kilometres at the Harts Range Project (Figure 8).

Highlights:

·    High-grade assay results at two new prospects, 'Paddington' and 'Westminster' confirm significant heavy rare earth element (HREE) targets west of Bobs Prospect

·    Outcrop sampling has delivered results including:

o  HRS019: 10.61% TREO (inc 1.28% Dy₂O₃, 0.22% Tb₄O₇) with 23.56% Nb₂O₅ and 15.67% Ta₂O₅

o  HRS031: 5.17% TREO (inc 0.61% Dy₂O₃, 0.10% Tb₄O₇) with 11.49% Nb₂O₅ and 7.30% Ta₂O₅

o  HRS032: 7.46% TREO (inc 0.53% Dy₂O₃, 0.05% Tb₄O₇) with 0.01% Nb2O₅ and 0.002% Ta₂O₅

·    These results, combined with findings from the Bobs and Cusp prospects validate an east-west trending structural corridor now extending over 2 kilometres at the Harts Range Project

·    High-grade multi-commodity Samarskite mineralisation has been identified showcasing exceptional HREE enrichment alongside significant Niobium & Tantalum values

·    Very high HREO/TREO ratios up to 96.69% highlight the dominance of Dysprosium and Terbium-two highly valuable magnet rare earth elements (REEs)

·    New Frontier Minerals is actively validating and reviewing all targets¹ with plans to drill test priority targets once suitable contractors have been appointed

 

Ged Hall, Chairman, commented: "We are extremely pleased with the results of the geophysical targeting and the systematic exploration efforts by the NFM geology team, which have led to the discovery of two new heavy rare earth targets at the Harts Range Project.

"Rock chip assay results from these newly identified Paddington and Westminster prospects have returned exceptional values including up to 10.61% TREO including 1.28% Dy2O3, 0.22% Tb4O7 with 23.56% Nb2O5 and 15.67% Ta2O5, confirming significant Heavy Rare Earth mineralisation. Together with the mineralised prospects Cusp and Bobs, the four prospects are associated with an east-west trending structural corridor now extending over 2 kilometres at the Harts Range Project.

"We are committed to unlocking the mineral potential of this strategic asset as quickly as possible in order to address the growing demand for rare earth elements, driven by the increasing use of clean energy technologies. The team will continue to actively validate and review all identified targets, and we look forward to drill testing high-priority prospects as soon as possible."

DISCOVERY OF NEW PROSPECTS PADDINGTON AND WESTMINSTER 

In April 2025, the NFM geological team commenced fieldwork at the Harts Range Project, aiming to accelerate exploration across previously untested areas within the tenure. Utilising the airborne geophysical radiometric imagery, the field campaign focused on following up radiometric targets and potential extensions of known uranium, heavy rare earth and niobium mineralisation. 

Returned assay results for samples have identified two promising new prospects, Paddington, and Westminster, located approximately 200m and 450m west of the mineralised Bobs Prospect, respectively (Figure 1).

PADDINGTON AND WESTMINSTER PROSPECTS

The pegmatite at the Paddington Prospect is located approximately 200m west of the Bobs Prospect. The outcropping pegmatite unit is seen to pinch and swell with a maximum width of 3m and is up to 40m in length and strikes east-west (Figure 1). Best results have returned (HRS019): 10.61% TREO (inc 1.28% Dy₂O₃, 0.22% Tb₄O₇) with 23.56% Nb₂O₅ and 15.67% Ta₂O₅.

The Westminster Prospect is situated approximately 450m west of the Bobs Prospect. Like the nearby Paddington prospect, it comprises a plagioclase and mica-rich pegmatite which has intruded within the surrounding amphibolite and has a prominent quartz cap. The pegmatite unit appears to be segmented into three distinct sections due to localised shearing, with the main outcrop trending east-west.

Notably, samarskite mineralisation is observed within the highly micaceous zones of the outcrop, with best results (HRS032) returning 7.46% TREO (inc 0.53% Dy₂O₃, 0.05% Tb₄O₇) with 0.01% Nb₂O₅ and 0.002% Ta₂O_5.

MINERALISED TREND 

The geophysical interpretation has identified an ENE trending structural feature that hosts all four mineralised prospects (Cusp, Bobs, Paddington, and Westminster). Preliminary interpretation has identified this to be potentially a controlling factor to the uranium, niobium, and heavy rare earths mineralisation (Figure 8). The addition of the new prospects (Paddington and Westminster) now extends this identified structural corridor over a 2km strike length.

The NFM geological team will be targeting repeats of these geophysical structural trends which have been interpreted to the north and south of the Bobs and Cusp Prospects. In addition to Cusp and Bobs, the Paddington and Westminster Prospects have been prioritised for drilling.

NEXT STEPS

 

With the commencement of the 2025 field season in April, New Frontier Minerals will continue to advance its exploration strategy at the Harts Range Project. Following the completion of geophysical interpretation and receipt of target generation data, the Company has now successfully completed exploration stages 1 through 4. (Figure 9).

New Frontier Minerals is committed to a thorough review of the 46 targets¹ identified during its exploration programme. The Company's goal is to drill test these targets after permitting and engagement of suitable contractors, enabling NFM to unlock the potential of its mineral assets and contribute to the growing demand for rare earth elements.
