("NFM" or the "Company")
NFM finalises HREE, Niobium and Uranium drill targets at Harts Range
New Frontier Minerals Limited ("New Frontier" or "the Company") (ASX and LSE:
NFM) is pleased to announce the geology team has finalised high priority
targets for drill-testing at its Harts Range Project, located 140km north-east
of Alice Springs in the Northern Territory. In addition, NFM aims to shortly
select a drilling contractor and secure regulatory approvals to enable an
inaugural RC drilling campaign to target Heavy Rare Earths Elements (HREE),
Niobium and Uranium mineralisation.
Highlights:
· NFM's geology teams recent field trip locked-in high-priority targets
at the Cusp, Bobs, Paddington and Westminster Prospects to test-drill for
Heavy Rare Earth Elements (HREE), Niobium and Uranium at the Harts Range
Project, NT
· Concurrently, NFM is reviewing quotes from prospective drilling
contractors and progressing regulatory approvals to fast-track a 2,000m -
3,000m Reverse Circulation (RC) drilling campaign
· Encouragingly, reflecting government support for the upcoming
campaign, NFM received a $59k grant from the NT Geological Survey's Geophysics
and Drilling Collaborations program
· Ongoing exploratory work comprised confirming the "Old Trafford
Prospect" (320m west from the Westminster Prospect) and investigating a
prominent magnetic feature circa 150-200m in diameter identified during the
recent geophysical survey and subsequent interprertation(1)
· An application (for 15.79 km(2)) has been lodged for tenement
(EL34147), south of the existing granted tenure (EL32513), to bolster the
exploration footprint at the Harts Range Project
Ged Hall, Chairman, commented: "Our geology team had a highly productive field
trip to the Harts Range Project, with key HREE, Niobium and Uranium targets
identified for drill-testing across the Cusp, Bobs, Paddington, Westminster
and the newly identified Old Trafford Prospect. A drilling contractor will be
appointed shortly, paving the way for the inaugural drilling campaign to
commence once regulatory approvals are in place. This is a critical inflection
point in the Harts Range Project's development which has the potential to
create significant value for shareholders."
High Priority Drill-Test Targets
During the month of June 2025, NFM's geology team spent several days at the
Harts Range Project finalising high-priority targets for drill-testing which
now include Cusp, Bobs, Paddington, Westminster and the newly identified Old
Trafford and Bank Prospect. The team has commenced regulatory approvals to
fast-track a 2,000m - 3,000m RC drilling campaign.
Ongoing Exploration Progress
In addition, the NFM geological team advanced field activities at the Harts
Range Project. The primary aim of the field campaign was to expedite
exploration over untested areas within the tenure and identify additional
radiometric targets and potential extensions to known Uranium, Niobium, and
HREE mineralisation.
Field inspection further west of Westminster has identified the Old Trafford
Prospect which comprises a plagioclase and quartz rich pegmatite outcrop with
minor muscovite intruded into surrounding amphibolite. A quartz cap is present
adjacent to the pegmatite unit which is seen to outcrop ~2m wide and ~50m in
length and trending E-W. Samarskite is noted to be present as fragments
dispersed consistently within the sample area in small clasts (1mm-1cm).
Geiger counter readings of up to 6 μSv were recorded with HSR066 sampled from
surface to 20cm deep. (Figure 1).
Further inspection at the Westminster Prospect has identified samarskite
mineralisation present amongst a highly micaceous section of the outcrop. The
discontinuous pegmatite outcrop has a quartz cap and displayed plagioclase and
mica rich alteration intruding through amphibolite. Geiger counter readings of
up to 8 μSv were recorded and the sample was collected ~5cm below surface
(HSR064, Figure 2). The outcrop is trending E-W, shearing trends at NE-SW.
North of Cusp, the Bank Prospect has noted copper mineralisation (malachite)
in foliated gneiss with a sugary quartz texture and biotite,
pyroxene/amphiboles in foliated bands (HRS055). The outcropping unit is seen
to trend N-S and noted to outcrop adjacent to a creek-bed. Fresh rock is white
in colour and more clearly exhibits visual malachite mineralisation with an
estimated grade is 0.5-3% Cu (Figure 3).
Note to Figure 1, 2 and 3: The nature of the mineral occurrence of samarskite
is seen as occasional scattered orthorhombic crystals. The minerals observed
are found in small quantities in the host pegmatite rock. The estimated
samarskite mineralisation abundance ranges from 0-2% in HRS066, 0-1% in
HRS064. The copper mineralisation in HRS055 is estimated to range from 0.5-3%
Cu. The anticipated timing for release of assays results related to the visual
estimates is 2-3 weeks.
A key area of interest is the southern tenement area where recent geophysical
surveys(1) identified a local magnetic anomaly at the Kings Cross Prospect
(Figure 4). Preliminary review of the magnetic data by Southern Geoscience
Consultants reveals that this feature is not an individual anomaly, rather a
combination of a series of smaller features to the west and one relatively
larger and prominent feature to the east which appears to be ~150-200m
diameter and 150m-200m depth.
Figure 1: Sample HRS066 (505626E, 7447478N) Figure 2:
Sample HRS064 (505851E, 7447578N)
Figure 3: Sample HRS055 (507782E, 7448068N
Cautionary Statement
Visual estimates of mineral abundance should never be considered a proxy or
substitute for laboratory analyses where concentrations or grades are the
factor of principal economic interest. Visual estimates also potentially
provide no information regarding impurities or deleterious physical properties
relevant to valuations.

Geophysical Target
A key area of interest is the southern tenement area where recent geophysical
surveys identified a local magnetic anomaly at the Kings Cross Prospect seen
in Figure 4 below.
Field inspection has located the geophysical anomaly to be immediately south
and associated with a prominent EW-trending fault that has been identified
from the 1:10,000 geophysical interpretation undertaken by Southern Geoscience
Consultants(1). In total, 12 samples (HSR033 - HSR044) were collected along
the EW structure and adjacent to the creek-bed, which appears to be associated
with the EW structure.

Northern Territory Government Grant
New Frontier Minerals has been awarded a $59,000 grant (inclusive of GST)
through the Northern Territory Geological Survey's Geophysics and Drilling
Collaborations program, part of the Resourcing the Territory initiative. This
includes a $10,000 Territory Supplier Incentive. The grant will support up to
1,360 meters of Reverse Circulation (RC) drilling at the Harts Range Project,
reducing the financial commitment for the Company's maiden drilling campaign
targeting HREE, Niobium, and Uranium. The Company is in the process of
finalising land access and environmental licensing to ensure compliance with
grant conditions, with a contract submission deadline of August 1, 2025.
Expansion of Footprint
New Frontier Minerals has applied for new tenure (EL34147), south of granted
Harts Range tenement (EL32513). This application for (15.79 Km(2)) bolsters
the exploration footprint and reflects the Company's commitment to expanding
its exploration footprint and developing high-potential critical mineral
resources in the region. Map of the new tenement application can be found in
Appendix C.
Strategic Context and Funding
The resumption of field activities aligns with New Frontier's commitment to
utilise the $1.59 million raised and the $59,000 government grant to
accelerate exploration at Harts Range. The macro environment remains
favourable, with U.S. government policies supporting the diversification of
HREE supply chains away from China and the acceleration of nuclear power
technologies. These developments enhance the strategic importance of HREE and
Uranium, positioning New Frontier to capitalise on growing demand for critical
minerals
Next Steps
Over the coming weeks, NFM geological team will:
· Continue field investigations, focusing on identifying priority
targets for drilling
· Analyse assay results from the Old Trafford, Westminster and Bank
Prospects to prioritise drilling targets
· Prepare for the maiden RC drilling campaign in Q3 FY25 subject to
government approvals
New Frontier remains committed to delivering value to shareholders through
disciplined exploration and development of its key assets.

· The Harts Range Niobium, Uranium-Heavy Rare Earth Project lies
north-west of the Entia Dome (Figure A2-1) and is underlain by the Harts Range
Group (Harts Range Meta-igneous Complex), which predominantly consists of
feldspar-biotite-amphibole-garnet gneisses.
· The Harts Range region has undergone repeated and substantial crustal
re-working between Proterozoic and Palaeozoic times. As a result, it is now
believed to represent an ancient and strongly altered/metamorphosed version of
a continental collision zone.
· Magnetotellurics data interpreted by a team consisting of Adelaide
University and NTGS geologists (Selway et al, 2006) suggests the Entia Dome
system is a deep-crustal feature that can be shown extending to the mantle.

poorly exposed zone on N side of ~6m thick unit/zone of similar rock (e.g.
HR398, HR399 sites) (on N side of HR399).
o Pegmatite, apatite-bearing: scree frags near W end of E- W pegmatite, near
intersection with north-south calcite vein; very coarse-grained
feldspar-quartz with common coarse apatite - pale semi-translucent slightly
greenish (rare honey-brown) blocky/tabular/hexagonal, some intergrown with

o Gneiss: weathered, moderately banded, fine-to-medium grained
quartz-feldspar-hornblende-garnet; some coarser quartz-garnet rock; some brown
haematite on fractures; sample below HR444.
o Ultramafics: slightly weathered medium grained, greenish/brownish
amphibole/olivine-dominated meta- ultramafic.
o Amphibolite: grey fine-grained hornblende -quartz rock; (approx. adjacent
rough channel samples: HR461 (1m) above HR462 (3m) above HR463 (3m) above
HR464 (1m)).
o Samarskite (or similar), being a dense brittle blackish lustrous
radioactive mineral; cluster of 10+ fragments, most over 1cm (or broken
weathered larger piece - ca. 5- 10 cm) in chalky white feldspar, beside
weathered coarse mica beneath soil cover along southern side of
