Inflection Resources Outlines Large-Scale Copper-Gold Targets on the Endurance Projects, Northern Territory, Australia

VANCOUVER, British Columbia, Oct. 30, 2025 (GLOBE NEWSWIRE) -- Inflection Resources Ltd. (CSE: AUCU / OTCQB: AUCUF / FSE: 5VJ) (the "Company" or "Inflection") is pleased to provide an update on its 100% owned Endurance Projects* located in Australia’s Northern Territory. The Endurance Projects were acquired from a subsidiary of Newmont Corporation (“Newmont”) and announced by the Company on June 16, 2025.

Summary Highlights:

• The Projects are located in Australia’s Northern Territory 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 mineral systems globally, with Australia's Olympic Dam, Prominent Hill and Carrapateena mines owned by BHP and the Ernest Henry mine owned by Evolution Mining being major sources of copper in Australia. IOCG deposits are attractive exploration targets due to their large scale and by-product potential, which includes gold and potentially uranium, which can greatly enhance project economics.
  
  
• The Endurance Projects are considered by the Company to be prospective for large-scale IOCG deposits of the style represented by Ernest Henry, Olympic Dam, Carrapateena and Prominent Hill mines.
  
  
• The Company considers the Endurance Projects to have the potential to represent a new IOCG province which has received minimal exploration. The projects are located in or in close proximity to a large, crustal-scale structure identified by the Australian federal government agency, Geoscience Australia and limited historic drilling which identified IOCG-style alteration and mineralisation.
  
  
• Drill core collected by Geoscience Australia, adjacent to the Bigeye (E1) target (Figure 4), contains an elemental association similar to that in hematite-rich ore zones at Olympic Dam, Prominent Hill and Ernest Henry. Furthermore, age dates obtained from the drill core suggest the area is geologically contemporaneous with the Ernest Henry IOCG mine.
  
  

Alistair Waddell, Inflection’s President and CEO, states: “We are excited to have completed the acquisition of this large portfolio of copper-gold projects in the Northern Territory. These assets strongly complement our ongoing programs in New South Wales and reinforce our strategy of drill-testing large-scale, high-impact copper-gold systems with Tier-1 discovery potential. With the exploration licences now formally transferred, we are actively advancing target prioritisation through the compilation of existing project and regional scale data and engaging with Aboriginal stakeholders. Inflection’s exploration strategy will continue to apply a mineral systems approach, utilising highest-quality geoscience to unlock the full potential of these large copper-gold targets.”

Endurance Projects:

The Endurance Project comprises twelve exploration licences totalling 4,592 km², strategically located in or in close proximity to a large, northeast-trending, crustal-scale geological structure considered by the Company to be a key fluid conduit that has the potential to localise IOCG copper-gold mineralisation (Figures 1 and 2).

These licences contain sixteen principal target areas, which typically comprise coincident aeromagnetic and Bouguer gravity highs, often with zones of elevated airborne electromagnetic (AEM) conductivity. These geophysical characteristics are similar to those at other large IOCG deposits in Australia and other parts of the world, including the Ernest Henry mine in Queensland and Olympic Dam in South Australia. The integrated geophysical signatures observed across the Endurance targets suggest the potential for IOCG alteration and mineralisation at depth.

The geology of the area is concealed beneath a blanket of younger, post-mineral rocks and alluvium cover estimated to be between 60 and 170 m thick. This cover sequence has impeded exploration in the region, leaving the prospective basement rocks largely untested despite their favourable geophysical expression. Modern exploration techniques, including high-resolution geophysical surveys and cost-effective drilling through cover, are now enabling the Company to effectively test these concealed targets for the first time.

Bigeye (E1) and Barreleye (E2) targets:
Based on work to-date, the Company considers the Bigeye target to be the most compelling and assigns it the highest priority for follow-up. The target is defined by a circular 8 km × 8 km aeromagnetic high coincident with a Bouguer gravity anomaly, positioned along a northeast-trending, crustal-scale structure interpreted to represent a major fluid conduit capable of localising mineralisation. A government-funded airborne electromagnetic (AEM) survey identified several discrete conductors close to the margin of the Bigeye circular magnetic feature, which Inflection interprets as being prospective for IOCG-style mineralisation.

A stratigraphic drill hole completed by Geoscience Australia into the northwestern portion of this target (Hole NDIBK07, Figures 3 and 4) intersected rocks which were dated and returned a maximum age of 1,652Ma, which suggests the area is geologically contemporaneous with the eastern succession of the Mt Isa Inlier, which hosts the Ernest Henry mine. Hole NDIBK07 intersected intensely hematite–pyrite altered sediments with quartz veining, which is considered highly encouraging in terms of potential prospectivity.   Inflection sampled the Geoscience Australia core, which returned assay results anomalous in barium, thorium, cerium, lanthanum, and yttrium with high potassium values that reflect an elemental association similar to that reported in hematite-rich zones at Olympic Dam, Prominent Hill and Ernest Henry (Belperio et al. 2007 and Rusk et al. 2010).

Government AEM survey interpretation shows large conductors on the margins of magnetic-gravity anomalies with similar characteristics to those seen at Ernest Henry, where sulphide accumulations occur on structural margins around an intrusive complex.

Collectively, the magnetic and Bouguer gravity anomalies with AEM conductors, the Mt Isa-age basement rocks and IOCG-style alteration suggest Bigeye could represent a district-scale intrusive complex capable of hosting IOCG-style mineralisation.
