ENDURANCE PROJECTS
Northern Territory, Australia
The Endurance Projects are a large-scale, district opportunity located east of the historic Tennant Creek mining camp in the Northern Territory, Australia. The project covers approximately 4,500 square kilometres and is considered highly prospective for Iron-Oxide Copper-Gold (IOCG) mineralization. The projects were acquired from a subsidiary of Newmont Corporation (“Newmont”) and announced by the Company on June 16, 2025

TARGETS
-
The Endurance targets are considered by the Company to be prospective for large-scale IOCG deposits, which comprise of prominent geophysical anomalies. These anomalies are located in or in close proximity to a large, crustal-scale structure considered by the Company to be a potential fluid conduit that may have localised IOCG mineralisation.
-
Regional-scale geophysical datasets reveal coincident magnetic, gravity and IP anomalies associated with interpreted breccias, ironstones and deep intrusive bodies — key features of large-scale IOCG systems.
FLASHLIGHT TARGET
The Flashlight Target exhibits a subtle aeromagnetic high coincident with an approximate 500 m x 400 m zone of elevated Bouguer gravity, suggestive of potential magnetite enrichment. Overlapping this anomaly is a zone of elevated chargeability identified by an induced polarisation (IP) survey, which is interpreted to represent possible sulphides at depth. Flashlight represents a high-conviction, high-priority drill target.

IRON OXIDE COPPER GOLD (IOCG) DEPOSITS
IOCG deposits are among the most metal-rich hydrothermal mineral systems globally, with Australia’s Olympic Dam and Ernest Henry ranked as two of the largest deposits in terms of contained copper, gold and by-product metals.
In South Australia, the Olympic Dam Mine is one of the world’s largest known deposits of copper, uranium and gold, hosted within Mesoproterozoic rocks. In Queensland, Ernest Henry is a magnetite-rich breccia pipe hosted in Proterozoic volcanics. Ernest Henry’s strong geophysical signature, particularly in magnetics, gravity and IP, serves as a working exploration model for Inflection’s Endurance targets. Additionally, BHP’s Carrapateena mining operation in South Australia and the Candelaria Mining Complex in Chile, owned by Lundin Mining Corporation are other examples of world-class IOCG districts.

The schematic block models are compiled from published studies and illustrate the geometries of zoned iron oxide-alkalic-calcic-hydrolytic alteration patterns and the location of Cu-Au ore bodies (Modified from Schlegel et al., 2020) – Schlegel et al. 2025
Exploration for IOCG deposits is typically guided by integrated geophysical surveys, with gravity and magnetic data forming the foundation of target generation. The distinctive density and magnetic contrasts created by iron oxide-rich alteration systems often produce characteristic anomalies that can be detected at depth, even beneath significant cover sequences. IP surveys have proven particularly valuable in delineating sulphide-bearing mineralisation within these systems, while detailed ground magnetic surveys can help define structural controls and breccia geometries. The discovery of concealed IOCG deposits often requires a systematic mineral-systems approach that combines regional-scale geophysical data interpretation with geological understanding of favourable host rock sequences and key structural settings.
