Inflection Resources Outlines Large-Scale Copper-Gold Targets on the Endurance Projects, Northern Territory, Australia
(TheNewswire)
Vancouver, British Columbia – TheNewswire - October 30, 2025 : Inflection Resources Ltd. (CSE: AUCU / OTCQB:AUCUF / FSE: 5VJ) (the "Company" or"Inflection") is pleased to provide anupdate on its 100% owned Endurance Projects* located in Australia’sNorthern Territory. The Endurance Projects were acquired from asubsidiary of Newmont Corporation (“Newmont”) and announced by theCompany on June 16, 2025 .
Summary Highlights:
The Projects are located in Australia’s NorthernTerritory and consist of twelve 100% owned exploration licences,totalling 4,592 km², covering sixteen large iron oxide copper-gold(“IOCG”) targets.
IOCG deposits are among the most metal-rich mineralsystems globally, with Australia's Olympic Dam, Prominent Hilland Carrapateena mines owned by BHP and theErnest Henry mine owned by Evolution Mining being major sources of copper in Australia. IOCG depositsare attractive exploration targets due to their large scale andby-product potential, which includes gold and potentially uranium,which can greatly enhance project economics.
The Endurance Projects are considered by the Company tobe prospective for large-scale IOCG deposits of the style representedby Ernest Henry, OlympicDam, Carrapateena and Prominent Hill mines.
The Company considers the Endurance Projects to havethe potential to represent a new IOCG province which has receivedminimal exploration. The projects are located in or in closeproximity to a large, crustal-scale structure identified by theAustralian federal government agency, Geoscience Australia and limitedhistoric drilling which identified IOCG-style alteration andmineralisation.
Drill core collected by Geoscience Australia, adjacentto the Bigeye (E1) target (Figure 4), contains an elementalassociation similar to that in hematite-rich ore zones at Olympic Dam,Prominent Hill and Ernest Henry. Furthermore, age dates obtainedfrom the drill core suggest the area is geologically contemporaneouswith the Ernest Henry IOCG mine.
Alistair Waddell, Inflection’s President and CEO,states: “We are excited tohave completed the acquisition of this large portfolio of copper-goldprojects in the Northern Territory. These assets strongly complementour ongoing programs in New South Wales and reinforce our strategy ofdrill-testing large-scale, high-impact copper-gold systems with Tier-1discovery potential. With the exploration licences now formallytransferred, we are actively advancing target prioritisation throughthe compilation of existing project and regional scale data andengaging with Aboriginal stakeholders. Inflection’s explorationstrategy will continue to apply a mineral systems approach, utilisinghighest-quality geoscience to unlock the full potential of these largecopper-gold targets.”
Endurance Projects:
The Endurance Project comprises twelve explorationlicences totalling 4,592 km², strategically located in or in closeproximity to a large, northeast-trending, crustal-scale geologicalstructure considered by the Company to be a key fluid conduit that hasthe potential to localise IOCG copper-gold mineralisation (Figures 1and 2).
These licences contain sixteen principal target areas,which typically comprise coincident aeromagnetic and Bouguer gravityhighs, often with zones of elevated airborne electromagnetic (AEM)conductivity. These geophysical characteristics are similar to thoseat other large IOCG deposits in Australia and other parts of theworld, including the Ernest Henry mine in Queensland and Olympic Damin South Australia. The integrated geophysical signatures observedacross the Endurance targets suggest the potential for IOCG alterationand mineralisation at depth.
The geology of the area is concealed beneath a blanketof younger, post-mineral rocks and alluvium cover estimated to bebetween 60 and 170 m thick. This cover sequence has impededexploration in the region, leaving the prospective basement rockslargely untested despite their favourable geophysical expression. Modern exploration techniques, including high-resolution geophysicalsurveys and cost-effective drilling through cover, are now enablingthe Company to effectively test these concealed targets for the firsttime.

Bigeye (E1) and Barreleye (E2)targets:
Based on work to-date, the Company considers the Bigeyetarget to be the most compelling and assigns it the highest priorityfor follow-up. The target is defined by a circular 8 km × 8 kmaeromagnetic high coincident with a Bouguer gravity anomaly,positioned along a northeast-trending, crustal-scale structureinterpreted to represent a major fluid conduit capable of localisingmineralisation. A government-funded airborne electromagnetic (AEM)survey identified several discrete conductors close to the margin ofthe Bigeye circular magnetic feature, which Inflection interprets asbeing prospective for IOCG-style mineralisation.
A stratigraphic drill hole completed by GeoscienceAustralia into the northwestern portion of this target (Hole NDIBK07,Figures 3 and 4) intersected rocks which were dated and returned amaximum age of 1,652Ma, which suggests the area is geologicallycontemporaneous with the eastern succession of the Mt Isa Inlier,which hosts the Ernest Henry mine. Hole NDIBK07 intersectedintensely hematite–pyrite altered sediments with quartz veining,which is considered highly encouraging in terms of potentialprospectivity. Inflection sampled the Geoscience Australia core,which returned assay results anomalous in barium, thorium, cerium,lanthanum, and yttrium with high potassium values that reflect anelemental association similar to that reported in hematite-rich zonesat Olympic Dam, Prominent Hill and Ernest Henry (Belperio et al. 2007and Rusk et al. 2010).
Government AEM survey interpretation shows largeconductors on the margins of magnetic-gravity anomalies with similarcharacteristics to those seen at Ernest Henry, where sulphideaccumulations occur on structural margins around an intrusive complex.
Collectively, the magnetic and Bouguer gravity anomalieswith A EMconductors , the Mt Isa-agebasement rocks and IOCG-style alteration suggest Bigeyecould represent a district-scale intrusivecomplex capable of hosting IOCG-style mineralisation.

The Barreleye (E2) target is an elongated,approximately 2.5 km × 0.5 km magnetic high that is coincident with abroad Bouguer gravity high, suggestive of a dense magnetic centre. An AEM conductivity anomaly is offset from the magnetic-gravityanomaly, consistent with potential sulphide accumulation on structuralmargins in Ernest Henry–style mineralisation. The target sitsalong a major structural corridor (Figure 1).

Fangtooth Targets (E3):
The Fangtooth target is a coincident magnetic andBouguer gravity high associated with a zone of elevated IPchargeability and resistivity. The Fangtooth West anomaly hasdimensions of approximately 3,000 m x 1,200 m and Fangtooth East hasdimensions of approximately 2,200 m x 1,200 m.
Flashlight Target (E10):
The Flashlight Target exhibits a subtle aeromagnetichigh coincident with an approximate 500 m x 400 m zone of elevatedBouguer gravity, suggestive of potential magnetite enrichment. Overlapping this anomaly is a zone of elevated chargeabilityidentified by an induced polarisation (IP) survey, which isinterpreted to represent possible sulphides at depth (Figure 5). Flashlight represents a high-priority drill target.

Other Targets:
Angler Target (E7) : An elongated, 8 km x 2 km geophysical target whichsuggests a coherent magnetic body coincident with a moderate gravityresponse and a strong, coincident AEM conductivity high. Moderatemagnetic relief coincides with the gravity high, while theconductivity suggests possible sulphides adjacent to a magnetic body.
Chimaera Target (E13) : A very large, 12.0 km × 2.5 km magnetic lineament with amodest gravity expression. The scale of the target suggests capacityfor multiple pipe or breccia-style IOCG centres focussed alongstructural margins and fold hinges.
Viper Target (E6) : An approximate 2,500 m × 1,200 m moderate magnetic highcoincident with a gravity low and an offset AEM conductivity high. Amoderate magnetic high coincident with low gravity and an offset AEMconductor suggest a discrete dense core with a potentialsulphide-bearing structural zone on the margin.
Loosejaw Target (E14) : Broad magnetic anomalism is coincident with aNE–SW-striking gravity anomaly, with a laterally offset AEMconductor nearby. The displaced conductivity anomaly hascharacteristics typical of potential sulphides on the flanks of amagnetite-bearing centre.
Lantern Target (E11): A compact, sub-kilometre magnetic high with a coincident,modest gravity high and a subtle, chargeable/conductive IP anomalywith a top interpreted to be 250 m to 300 m below surface. Scoutdrilling in the vicinity of the target by Newmont intersected a broadzone of disseminated pyrite in iron-rich metasediments which returned4 m grading 0.2% Cu from 218 m.
Hook Target (E8): Two discrete magnetic high anomalies of approximately3,000 m × 1,500 m each with coincident gravity highs.
Goblin Target (E12): A large, 5,000 m × 3,000 m magnetic anomaly coincidentwith a zone of subtle gravity. The magnetic geometry is consistentwith a concealed intrusive centre.
Daggertooth Target (E4) : A 3,000 m × 1,000 m coincident magnetic and gravity highwhich aligns with a strong IP chargeability anomaly and moderateresistivity contrast.
Next steps:
The Company is working through general permitting andland access agreements. While the Company is still assessingoptions, a program of first-pass air-core drilling across the targetsin the first half of next year after the wet season is being planned. Air-core drilling is a very cost-effective method of drillingthrough post-mineral cover and can include short diamond-core tailsinto the prospective basement sequence.
Iron Oxide Copper Gold(IOCG) Deposits:
IOCG deposits are among the most metal-richhydrothermal mineral systems, with Australia's Olympic Dam andErnest Henry ranked as two significant deposits in terms of containedcopper, gold and by-product metals.
In South Australia, the Olympic Dam Mine is one of theworld's largest known deposits of copper, uranium and gold,hosted within Mesoproterozoic rocks containing Mineral Resources of10,160 Mt at 0.26 g/t Au and 0.6% Cu, plus Ore Reserves of 591 Mt at0.26 g/t Au and 0.6% Cu (BHP Group Limited2025). In Queensland, Ernest Henry is a magnetite-rich breccia pipehosted in Proterozoic volcanic rocks, containing Mineral Resources of110 Mt at 0.77 g/t Au and 1.26% Cu, plus Ore Reserves of 78 Mt at 0.46g/t Au and 0.76% Cu (Evolution Mining Limited 2025, June 6). ErnestHenry’s strong geophysical signature, particularly in magnetics,gravity and IP, serves as a working exploration model forInflection’s Endurance Projects. Additionally, BHP’sCarrapateena mining operation in South Australia and the CandelariaMining Complex in Chile owned by Lundin Mining Corporation are otherexamples of world-class IOCG districts.
Exploration for IOCG deposits is typically guided byintegrated geophysical surveys, with gravity and magnetic data formingthe foundation of target generation. The distinctive density andmagnetic contrasts created by iron oxide-rich alteration systems oftenproduce characteristic anomalies that can be detected at depth, evenbeneath significant cover sequences. IP surveys have provenparticularly valuable in delineating sulphide-bearing mineralisationwithin these systems, while detailed ground magnetic surveys can helpdefine structural controls and breccia geometries (Figure 6). Thediscovery of concealed IOCG deposits often requires a systematicmineral-systems approach that combines regional-scale geophysical datainterpretation with geological understanding of favourable host rocksequences and key structural settings.

About Inflection’s NorthernTerritory Projects:
The Company is systematically exploring for large copper-gold deposits in the Northern Territory,approximately 185 km east of Tennant Creek. The Company hasapproximately 4,600 km² of 100% owned exploration licences covering awide variety of large geophysical targets that were generated byNewcrest Mining Limited, subsequently acquired by Newmont Corporationand highlighted by a country-wide AEM geophysical survey and analysisby Geoscience Australia (Skirrow et al., 2019). The AEM surveyhighlighted large-scale, deep-seated, crustal-level structuresinterpreted by the Company to be ideal for hydrothermal fluid pathwayscritical for the formation of IOCG deposits. Initial scout drillingon several targets by Newcrest returned encouraging results,confirming the potential for large, yet to be discovered, copper-golddeposits.
