New Frontier Minerals Limited

("NFM" or the "Company")

 

Harts Range continues to deliver Heavy Rare Earth Mineralisation at surface

 

New Frontier Minerals Limited (LSE/ASX: NFM) is pleased to announce the
geology team has identified additional high priority targets for drill-testing
at its Harts Range Project, located 140km north-east of Alice Springs in the
Northern Territory, Australia.

 

Assay results from the June 2025 field program have confirmed a new drill
target and new prospect - Old Trafford - located approximately 320m west of
the mineralised Westminster Prospect. This new prospect, along with the
mineralised prospects - Cusp and Bobs, Paddington, and Westminster - occur
within an east-west trending structural corridor now extending over 2.4
kilometres at the Harts Range Project.

 

Highlights

·    Rock chip assay results at new prospect, 'Old Trafford' extends
significant Heavy Rare Earth mineralisation continuous and complementary to
Cusp, Bobs, Paddington and Westminster.

·    Old Trafford located 320m west from the Westminster Prospect returns:

o  0.73% TREO (inc 0.097% Dy2O3, 0.015% Tb4O7) with 1.92% Nb2O5 and 0.31%
Ta2O5.

·    Additional mineralisation from the Westminster Prospect includes:

o  HRS064: 7.34% TREO (inc 0.55% Dy2O3, 0.06% Tb4O7) with 0.008% Nb2O5 and
0.002% Ta2O5.

·    Bank Prospect returns anomalous copper results with best results
returning up to 2.72% CuO from rock chip samples.

·    Assay results from the July field program have been submitted for
geochemical analysis with results expected by early August 2025.

·    NFM is progressing regulatory approvals and reviewing quotes from
drilling contractors to fast-track a 2,000m - 3,000m Reverse Circulation (RC)
drilling campaign.

 

Chairman Gerrard Hall commented: "We are very pleased with the outcomes of the
June 2025 exploration program conducted by the NFM geology team, which has led
to the discovery of the Old Trafford Prospect and additional Heavy Rare Earths
targets at the Harts Range Project. The rock chip assay results from the newly
identified Old Trafford prospect have confirmed and extended the presence of
Heavy Rare Earth mineralisation as well as significant Niobium and Tantalum
mineralisation a further 320 metres west of the Westminster Prospect. The
Company remains committed to unlocking the full mineral potential at Harts
Range and is currently advancing regulatory approvals and reviewing quotes
from drilling contractors to fast-track our maiden drilling program."

 

DISCOVERY OF NEW PROSPECT - OLD TRAFFORD

The NFM geological team commenced ongoing fieldwork during the month of June
2025 at the Harts Range Project, to further identify prospects and targets for
drilling across previously untested areas within the mineralised east-west
trending structural corridor. Utilising the airborne geophysical radiometric
imagery, the team identified further targets and extensions of Heavy Rare
Earths, Niobium and Uranium mineralisation at the newly identified Old
Trafford Prospect (Table1).  The Old Trafford prospect extends mineralisation
a further 320m west of the Westminster Prospect.

 

Additional rock chip samples (namely HRS064) from the Westminster Prospect
have also returned significant assay results and validates Westminster as a
priority target for drilling

 (Table 1).

 

 SAMPLE  PROSPECT      TREO (%)  Dy(2)O(3) (%)  Tb(4)O(7) (%)  Nb(2)O(5) (%)  Ta(2)O5 (%)  HREO/TREO (%)
 HRS066  OLD TRAFFORD  0.73      0.097          0.015          1.92           0.31         82.4
 HRS064  WESTMINSTER   7.34      0.55           0.06           0.008          0.002        95.57
 HRS032  WESTMINSTER   7.46      0.53           0.05           0.01           0.002        96.69

BANK COPPER PROSPECT

North of Cusp, the Bank Prospect has identified copper mineralisation
(malachite) in foliated gneissic rocks. The outcropping unit is discontinuous
and seen to trend a north-south orientation and is noted to outcrop adjacent
to a creek-bed over 200 metres away. Numerous rock chip samples from the
exposed outcrops have returned anomalous copper assay results (Table 2).

 

 SAMPLE ID  CuO (%)
 HRS053     1.38%
 HRS054     1.08%
 HRS055     0.82%
 HRS056     0.20%
 HRS058     0.99%
 HRS059     0.23%
 HRS061     0.99%
 HRS062     2.72%

Further validation may require the use of ground geophysics including IP or EM
surveys to further validate and prioritise targets at depth for drilling at
the Bank Prospect.

GEOPHYSICAL TARGET

The recent airborne geophysical survey identified a local magnetic anomaly at
the Kings Cross Prospect which is located to the south of the project area
(Figure2). Twelve rock chip samples (HSR033 - HSR044) were collected along the
east-west structure, which appears to the north of the magnetic anomaly.

 

Sample HRS035 displays the most notable geochemical results, particularly in
Light Rare Earth Elements (LREEs), with elevated values in CeO2 (196 ppm),
La2O3 (111.9 ppm), Nd2O3 (86.7 ppm), Pr6O11 (24.4 ppm), and Sm2O3 (16.1 ppm).
The results suggest a localised enrichment of LREEs relative to surrounding
samples, which exhibit only modest background levels. While no high-grade
concentrations are present, the clustering of elevated LREEs in HRS035 may
warrant further exploration and follow-up sampling to investigate potential
mineralised trends.

 

Further validation may require the use of ground geophysics to further
validate and prioritise the geophysical target for drilling at the Kings Cross
Prospect.

NEXT STEPS

Over the coming weeks and months, the NFM geological team will:

·    Continue field investigations, focusing on identifying and defining
priority targets for drilling at the Cusp, Bobs, Paddington, Westminster and
Old Trafford Prospects.

·    Analyse assay results from the known mineralised prospects in order
to prioritise drilling targets further west of Paddington.

·    Progress regulatory approvals and review quotes from drilling
contractors in preparation for the maiden RC drilling campaign in Q3 FY25.

 

New Frontier remains committed to delivering value to shareholders through
disciplined exploration and development of its key assets.
