Exploration Targets Demonstrates Significant

Potential at NWǪ Copper Project

New Frontier Minerals Ltd (LSE and ASX: NFM) is pleased to announce updated JORC Exploration Targets (to the standard of Clause 17 of the 2012 JORC Code) across 14 prospects within NWǪ Copper Project, located in the Mt Isa region of northwest Ǫueensland.

Highlights

·    High-tenor, strike-extensive copper and in several cases Cu-Pb-Zn anomalism, supported by a combination of geophysics, geochemistry, and historical drilling underpins the potential for further characterising structurally controlled copper deposits within the NWǪ Copper Project

·    New Frontier's geology team has delineated 14 priority prospects within the NWǪ Copper Project (Mt Isa region, Ǫueensland) which holistically demonstrates significant exploration potential

·    The geology team's proposed development pathway comprises the following steps:

o  Secure the mining lease over the Big One Deposit (MRE: 2.1Mt @ 1.1% Cu for ~21kt copper metal) 1, which is currently under review by the Ǫueensland regulator

o  Leveraging the alignment with Austral Resources (ASX:AR1), formalise a revenue sharing arrangement to have copper ore processed at the Mt Kelly facility²

·    Future development work across the NWǪ Copper Project, which could create significant

·    incremental value for shareholders, includes:

o  Progressing RC and diamond drilling campaigns at the Big One and Big One North Deposits to potentially extend known mineralisation and upgrade the current MRE^3,4

o  Site visits to the 14 other under-explored priority prospects to ascertain their potential to host copper deposits

Chairman Gerrard Hall commented: ""The Exploration Targets underscore the substantial potential scale and depth of opportunity across the NWǪ Copper Project. Moreover, they clearly demonstrate significant exploration potential beyond the Big One Deposit.

New Frontier's initial focus is to secure a mining lease over Big One Deposit and formalise a copper ore processing agreement with Austral Resources to utilise its Mt Kelly facility. In due course, the development pathway comprises fully developing the Big One Deposit, then explore the remaining 13 prospects to determine their potential to host copper deposits. Collectively, this work highlights the NWǪ Copper Project's potential to have multiple copper deposits with a clear production pathway, that could generate significant value for shareholders."

EXPLORATION TARGETS

The updated Exploration Target1 estimate ranges from 12-58 million tonnes (Mt) @ 0.3-1.5% Cu, representing circa 50,000-473,000t of contained copper. This has been defined across 14 priority prospects within New Frontiers' NWǪ Copper Project, Mt Isa region, Ǫueensland (Table 1).

The updated targets reflect a comprehensive technical review of historical open file datasets, combined with exploration data generated by the NFM since 2018 ^6,7. This work builds on earlier ROM Resources studies and incorporates subsequent prospect ranking exercises completed internally between 2023-2025^8,9

Cautionary Statement¹

It should be noted that the Exploration Target tonnage ranges quoted above are conceptual in nature and there has been insufficient exploration to define a copper resource. Although a preliminary analysis was undertaken, insufficient data exists to confidently correlate mineralised horizons within the Exploration Target area. It is uncertain whether further exploration may lead to the reporting of a JORC-standard resource however there is some evidence to support the current exploration tonnage calculations, and the sufficient mineralised thicknesses interpreted from historical drilling to warrant further investigation in some areas.

CURRENT WORK

The purpose of this extensive study was to highlight and prioritise prospects across New Frontier Minerals' NWǪ Copper Project (PROJ0221) in the Mt Isa Region of Northwest Ǫueensland (Figure 1 C 2), using available open file historical data and that generated by NFM (previously Castillo Copper Limited) since 2018 for each prospect as of the 1st of January 2026. This study represents an update to work completed by ROM Resources in 2019-2020 and various ASX releases during 2020. Recently, a comprehensive ranking exercise was completed in 2023 and reported to the ASX⁵ that provided additional information.

New Frontier has applied a systematic approach that has included mapping, geochemistry, and geophysics to identify, define and prioritise multiple drill ready targets. Targets consist of up to 100- 500m long, 5-20m-wide gossanous breccias with strongly anomalous copper and key geochemical pathfinders (Ag, Co, As, Sb, Bi). These targets are hosted in two structural clusters, 15km apart, bisected by a major, northeast-trending unnamed regional fault.

NWQ COPPER PROJECT - KEY PROSPECTS

REGIONAL GEOLOGY HIGHLIGHTS COPPER PROSPECTIVITY

TThe NWǪ Copper Project lies at the northern limits of a block of Haslingden Group volcanic and sedimentary rocks including the Eastern Creek Volcanics which lie within a large north-trending graben structure (Leichhardt River Fault Trough), forming a north plunging complexly faulted anticline. The Haslingden Group forms the basement to sedimentary rocks which include the Mount Isa Group (Blake, 1987) (Domagala, Southgate, McConachie, C Pidgeon, 2000) (Page C Sweet, Geochronology of basin phases in the western Mount Isa Inlier, and correlation with the McArthur Basin, 1998) (Southgate, Neumann, C Gibson, 2013).

The Mount Gordon Fault, a major structural element in the Mount Isa Inlier, bounds the Leichhardt River Fault Trough to the west. The Leichhardt River Fault contains the most significant of the Proterozoic base metal deposits in the Inlier including those at Mount Isa and Hilton (George Fisher). Other deposits including those at Mount Gordon and Mount Oxide lie within the Mount Gordon Fault Zone itself. A north-east trending branch of the Mount Gordon Fault passes to the east of the NWǪ Copper Project (Figure 3).

Younger Proterozoic sedimentary rocks occur along both the eastern and western margins of the Leichhardt River Fault Trough and between the faulted 'segments' of the Haslingden Group rocks. These marginal sedimentary rocks commonly host mineral deposits probably for two reasons: the sedimentary rocks are adjacent to the faulted margins of the graben structure where there has been greater fluid flow and, the sedimentary rocks were being laid down during a major mineralizing episode. Most of the rocks that are equivalent to the Mount Isa Inlier host sedimentary rocks have been removed by erosion of the Leichhardt River Fault Trough (Wilde, 2011).

Within the vicinity of the Big One Copper Deposit, small areas of Mount Isa Group equivalent rocks exist in narrow synclinal areas. These lie under a shallow cover of Mesozoic and Cainozoic sedimentary rocks in the northern portion of the area (Figure 3).

EXPLORATION RATIONALE

Several copper prospects and indications of copper mineralisation are known in the area,

mineralisation styles vary, namely:

·    Structurally controlled Cu (IOCG)

·    Sheared-hosted sedimentary rocks Cu-Au

·    Stratiform Pb-Zn; and

·    Unconformity-hosted U

Almost without exception, copper mineralisation is hosted within the upper rock units of the Paradise Creek, Ǫuilalar, and Surprise Creek Formations. The latter is a unit consisting of laminated shales and siltstones, often carbonaceous and graphitic, dolomitic silty sandstone, in places stromatolitic, and quartzites with interbedded argillite and sandstone. The unit is prominent as weak anomalies on regional airborne AEM surveys. Regionally, this unit is preferentially weathered and outcrops poorly and is often covered in quartzite scree from the overlying Warrina Park Ǫuartzite. Minor occurrences of copper mineralisation are also reported from the Whitworth and Warrina Park Ǫuartzite usually in the form of turquoise (copper phosphate).

RESOURCE TABLE

Each Exploration Target2 estimate is supported by sufficient geological, geophysical, geochemical, and occasional sparse drilling data to constrain scale and tenor. Full details of the target generation methodology, data validation, and estimation approach are provided in Appendix 1 through to 4 in accordance with the JORC Code (2012).

An Exploration Target range (to standard of Clause 17 of the 2012 JORC Code) has been estimated for 14 copper prospects (Big One, Eldorado North and South, Pancake, Mt Storm, Crescent, Crescent East, Valparaisa, Arya, The Wall, Flapjack, Johnnies, Amanda, Pandanus Creek, and Black Mountain; Tables 1, 2 C 3) by ROM Resources and some previously reported internally by R3D Resources (Biggs and Reed 2022).

Note these Exploration Target2 estimates are in addition to the small JORC Indicated and Inferred MRE (Table 4) previously reported at Big One Deposit (Biggs 2022, Paull 2022). Moreover, the 14 Exploration Targets provide a preliminary estimate and base position for future development.

Cautionary Statement²

It should be noted that the Exploration Target tonnage range quoted above are conceptual in nature and there has been insufficient exploration to define a copper resource. Although a preliminary analysis was undertaken, insufficient data exists to confidently correlate mineralised horizons within the Exploration Target area. It is uncertain whether further exploration may lead to the reporting of a JORC-standard resource however there is some evidence to support the current exploration tonnage calculations, and the sufficient mineralised thicknesses interpreted from historical drilling to warrant further investigation in some areas.

Cautionary Statement³

It should be noted that the Exploration Target tonnage range quoted above are conceptual in nature and there has been insufficient exploration to define a copper resource. Although a preliminary analysis was undertaken, insufficient data exists to confidently correlate mineralised horizons within the Exploration Target area. It is uncertain whether further exploration may lead to the reporting of a JORC-standard resource however there is some evidence to support the current exploration tonnage calculations, and the sufficient mineralised thicknesses interpreted from historical drilling to warrant further investigation in some areas.

The total insitu contained copper is approximately 22,000 t (Table 3). Separately, if one considers the low range of the Exploration Targets that is approximately 50,000 t (Table 1).

INDIVIDUAL SUMMARIES

At the Eldorado South Copper Prospect surface sampling campaigns have returned up to 5,400ppm Cu in rock chip samples, suggesting the presence of structurally controlled copper-gold system. Moreover, this may be linked to a major NNE trending fault. The interpreted anomalous zones should be prioritised for follow-up field work and potentially drilling in Ǫ3 2026.

The Pancake Prospect has Mt Isa style mineralisation potential. Soil samples along an east-west trending anomalous zone delivered positive readings for zinc-lead-copper mineralisation with peak values for rock chips up to 7,100ppm Zn, 2,000ppm Pb and 670ppm Cu. As these reconcile favourably with two (2) sub-surface anomalies identi6ed with ground geophysics, they are priority targets to be test-drilled incrementally.

At the Big One Deposit three (Figure 2) exploration campaigns have been conducted which has produced an Inferred MRE of 21,556kt contained copper. An Exploration Target1 that ranges between 2 to 6Mt and 0.6 to 1.0% Cu for a mid-range of 30,000 insitu tonnes Cu has also been estimated using available geophysics C geochemical data (Figure 4). A planned Stage 3 drilling campaign, comprising infill C testing a sizeable conductor north of the line of lode should extend known mineralisation plus increase the confidence / grade of the current MRE has recently been scoped by infill soil and rock chip sampling completed during August 2024 (Logan 2024).

Also, some 300m to the north is the Big One North extension (Figures 5 and 6), with a small wireframe target (up to 120m in length) based on IP conductivity shells of >8 mv/v and scattered rock chip mapping. This has an estimated range of 0.2 to 1.7Mt and grade 0.3 to 0.9% Cu. As with Big One, drilling is planned for Ǫ3 2026.

Note: Coordinate System is MGA2020-Z54S

The Valparaisa Copper Prospect consists of copper mineralisation in two horizons over a 6km strike event. Previous explorers, including BHP, found rock chips with up to 2,530ppm Cu. Reconciling this against the interaction of two intersecting faults suggest a structurally controlled copper system that could be drill-tested. R3D Resources had estimated a range of 1.3 to 3.5Mt and grade 0.2 to 0.5% Cu.

At the Arya Prospect there is a significant magnetic anomaly, south of a known graphite system, which shows potential to be a primary source of copper mineralisation. Further field work is necessary to determine the relationship between the structure and mineralisation, prior to a proof- of-concept campaign to drill-test the magnetic anomaly.

At the Mt Storm Copper Prospect previous small scaling mining extracted approximately 1,100t of ore with a head grade at 6% Cu. Subsequent fieldwork found copper-cobalt at surface with gold nearby which could form part of a structurally controlled system along a porphyry dyke. Further fieldwork is required, and a small reverse circulation (RC) drilling campaign is recommended if compelling evidence is found.

The Black Mountain Copper Prospect was the subject of company rock chip sampling in late 2021, which returned anomalous copper values up to 940ppm from the ferro-manganiferous outcrop. Further follow up surface sampling and geophysics campaigns to identify potential targets for drill- testing are recommended.

The Wall is a Mt Isa-style Copper/Lead/Zinc Prospect, having an anomalous zone 400m long by 225m wide with soil samples that assayed up to 7,163ppm Zn, 2,023ppm Pb and 1,464ppm Cu coincident with an airborne GEOTEM conductor.

The Flapjack Copper Prospect saw MIM complete a range of geological investigations, including extensive surface sampling campaigns at the Flapjack prospect but no drilling. Bear in mind the best gold assay at Crescent is 170ppb Au for a stream sediment sample that showed visible panned gold). There were consistently elevated gold values than the Crescent prospect - the IOCG alteration appear to be closer to where IOCG "ore forms" or is situated in the IOCG mineral system - Tick Hill had been located following up a 7ppb stream sediment anomaly, Tick Hill is a unique deposit, but it falls within the IOCG spectrum of deposits. A total of 31 rock chip samples were collected over the Flapjack Prospect grid with the highest values of 606ppm Cu, 404ppm Pb, 463ppm Zn, 4.3ppm Ag and 1.37ppm Au.

The historical reports indicate that the there is "red rock"- "green rock" alteration, the petrographic reports should be examined in detail, and if possible, compared to the distinct similar style of observed altered rock at Tick Hill. Tick Hill is an IOCG deposit and there are papers published on its "discovery" (attention should be directed towards visible alteration, surface sample assay values, etc, to compare/contrast what is at Flapjack).

An aerial GEOTEM geophysical anomaly exists to the south-west of the Flapjack prospect. A review of this and other geophysical RTP and TMI surveys should be completed - as it is possible that potentially, when considering the other datasets, that geophysical-geochemical-alteration anomaly exists in proximity to the Flapjack prospect data sets.

The Pandanus Creek (previously called Camel Back East) and Johnnies prospects are similar in that they are shear-hosted copper-lead-zinc deposits with rock chip assays up to 59,100ppm Cu, 9,500ppm Zn and 45,000ppm Pb. In addition, at Jonnies two 16m long costeans were constructed, mapped, and sampled which produced similar values from a 5m composite sample. Complementing the geochemical work, an induced polarisation ground survey identified two anomalies: one with a low phase response that is potentially sulphide mineralisation continuing down plunge, while the other is a north-trending downwards plunging anomaly, neither of which have been drilled.

Crescent and Crescent East prospects includes a zone of structurally controlled east-northeast trending haematitic-quartz veins, that appear to be situated along trend from the Crescent Prospect. Identification of haematitic-quartz veins laced with gold, and other alteration features are arguments for IOCG mineralisation. Cu-Au mineralisation could be related to structurally controlled mineralisation associated with the fault zone and/or stratabound copper. Skarn alteration identified to the north of the fault in the dolomites, dolomitic breccias, with the Ǫuilalar Formation sandstone and quartzite, is distinctly different alteration to the chlorite alteration mapped.

Amanda was identified as a quartz shear vein (150m by 5m wide) associated with an easterly- trending fault within the Lochness Formation. Gold values as high as 4ppm in soil sampling led to the drilling of five south-dipping shallow RAB holes that failed to find elevated gold values above 100ppb, but did intersect copper values as high as 3,000ppm.

SAMPLING TECHNIQUES

Over the 40-odd years of modern exploration has resulted in a wide diversity of methodologies

employed.

Regional Magnetics

The 100m line spacing and 60 vertical clearances reported for the available dataset is of sufficient density.

Gradient Array Induced Polarity

At Pancake the 100m line spacing and 25m dipole spacing, as well as perpendicular orientation of

the survey lines is of high-quality and more than sufficient.

Surface Geochemistry

Surface stream sediment, soil and rock chip samples have been collected by MIM, BHP, CST Minerals, and other explorers generally a different spacings depending upon the deposit (for soil 100m spaced lines, <20m spacing) are of sufficient density for the purposes reported here. Closer line spacing is required in some areas.

Rock chip sampling at Black Mountain is of sufficient density for the purpose of report. Additional work is still required to close of the anomaly(s). Sample data of Crescent, Pancake, and Eldorado is of high-density and sufficient for the purpose reported here. Analyses collected over Crescent are sufficient to identify strike extension of surficial anomalism, while more work is still required to define the width of anomalism, and additional strike orientation.

Conventional Soils

At many of the Prospects 25m x 100m line spacing extending to 25m x 400m at extremities of the grid. Sample spacing is suitable for the definition of the anomaly for further exploration interrogation. Further work is planned to improve the definition of the anomalism.

Costean and Mullock Composites

Costean mapping and sampling and collection of mullock composite samples at Johnnies reported

here are of sufficient density for the purpose in which is reported and used.

Drilling

Drilling at the Pancake Prospect is broadly-spaced along strike (~120m), and 40m spaced in section which has been sufficient in the reporting of the inferred resource. Additional resource definition drilling is planned for Mt Storm and The Wall. Downhole logging is regular 1m intervals and is sufficient. Exploration RC drilling at Amanda and Valparaisa is exploratory in nature. Downhole sampling of 4m composites is sufficient for initial exploratory drilling.

SAMPLE ASSAY

For the various drilling programs will be composited every two or four metres and all samples were collected to maximise optimal representation for each sample. In all cases for the historical drilling sampling was not continuous and narrow in scope (Cu, Pb, Zn, As, and sometimes Au (e.g. Amanda).

Each metre sample had an amount removed for washing and cleaning and sieving then place into metre allocated chip trays. These chips were logged on site by the rig geologists and those logs have been saved into a spreadsheet and stored on the Company server. Any visible mineralisation, alteration or other salient features were recorded in the logs. Industry-wide, acceptable, standard practices were adhered to for the drilling and sampling of each metre as per the Drilling and Sampling Procedures set out before commencement of the drilling program, although drilling pre 1998 did not include ǪA/ǪC checks for the laboratory assays.

Any reporting of significant mineralised intervals was on a received apparent thickness x interval calculation (i.e., thickness averaged). All geochemical samples to be laboratory assayed are uniquely numbered and dispatched via courier to ALS Mount Isa where they are logged into the laboratory system on delivery. From there, the prepared samples are freighted to Townsville or Brisbane laboratories, where they underwent analysis using varying techniques developed over time.

CUT-OFF GRADES

Copper cut-off grades varied per deposit/prospect was assumed for potential open pit material down to 60 m below the surface. Below this level the stripping ratio is likely to be too high for open pit extraction. These cut-off grades are preliminary in nature and are subject to confirmation by feasibility work on the project.

CLASSIFICATION CRITERIA

Insufficient data exists at all Prospects investigated to preclude Mineral Resource classifications being assigned. At Big One a block model was generated only for the main deposit and not the northern extension. At Big One, Inferred resource blocks required the closest sample within 55m on the second pass, an average sample distance <35m, and a minimum of three drill-hole samples, with the remaining blocks between 80-190m, previously unreported, have now been assigned to an Exploration Target4.

RESOURCE ESTIMATE

Due to the lack of both volume and sufficient spacing of drilling data, even at prospects that have drilling, no JORC-standard Resources are possible to be estimated. Certainly, at Big One and Big One North, a well-placed drilling program has the potential to greatly increase this number and confidence class, as the deposit is open to the north, east, and downdip. Estimates of mine stockpiles at Mt Storm have not at this time been included, as detailed drone-based surveying will be required to assess their extent more accurately. All the Exploration Targets4 tabulated are generally calculated at depths of <80m below ground, and hence it is likely that any insitu ore will be partially to completely oxidised.

METHODOLOGY

For Exploration Targets4 estimated (to the standard of Clause 17 of the 20212 JORC Code) the

following methodology was applied:

Except for Big One Deposit where a wireframe or enclosing shell was generated surrounding the Inferred Resource shell, all other estimations were based on simple geometric shapes of the form:

Length (m) x width (m) x depth (m) x density (Kg/m3)

to obtain wireframe volumes then mass (tonnes) across a reasonable minimum and maximum range.

Except for Big One Deposit where core has been tested for specific gravity, following global average density of 2.2 g/cc for oxidized material, 2.55 for partially weathered rock and 2.75 for fresh rock was used to estimate total in situ tonnes with no constraints.

⁴ It should be noted that the Exploration Target tonnage ranges quoted above are conceptual in nature and there has been insufficient exploration to define a copper resource. Although a preliminary analysis was undertaken, insufficient data exists to confidently correlate mineralised horizons within the Exploration Target area. It is uncertain whether further exploration may lead to the reporting of a JORC-standard resource however there is some evidence to support the current exploration tonnage calculations, and the sufficient mineralised thicknesses interpreted from historical drilling to warrant further investigation in some areas.

Unexpected geological loss mainly due to faulting and discontinuous mineralisation over large distances between any drillholes used, expressed as a % deleted from the original insitu tonnages estimated. Typically, loss of 20-60% was applied.

Where quoted, it should be noted that where Exploration Target tonnages are estimated in the report, they are considered non-JORC and are conceptual in nature. There has been insufficient exploration to define an MRE and that it is uncertain if further exploration will result in the determination of an MRE.

Some surface and rare drilling assay data within the project area was uncovered in historical reports. Big One Deposit and Mt Storm and to a lesser degree Valparaisa and Black Mountain have been previously mined. Scattered historical drilling was conducted at Amanda, Pancake, Johnnies, and Valparaisa.

Although a preliminary analysis was undertaken, insufficient data exists to confidently correlate mineralised domains and generate a grid mesh or block model. It is uncertain whether further exploration may lead to the reporting of a JORC-standard resource however there is some evidence to support the current exploration tonnage calculations, and the sufficient surface and downhole thicknesses interpreted from historic drilling to warrant further investigation in some areas.

CONCLUSIONS

In summary the top five prospects (Big One Deposit (and Big One North), Mt Storm, Eldorado South, the Wall, and Pancake) require further fieldwork to firm locations for small confirmatory RC drilling programs. In the case of Big One Deposit, further deep drilling along the line of lode is expected to encompass diamond drill core drilling with further metallurgical sampling.

STRATEGY

·    Assessment of priority NWǪ prospects and targets for drilling.

·    Continue engagement with the Ǫueensland Natural Resources and Mines Department as the Big One Deposit MLA advances through the technical assessment.

·    Progress assessment of priority mining areas and historical stockpiles outside the current

·    Mineral Resource Estimate.

·    Receive and assess assay results from the Harts Range Heavy Rare Earths drilling program

and continue to improve the beneficiation process with Metallium.

·    Expand OTC investor outreach to improve market visibility of core assets.
