Rare Earth Metallurgy Update – Head Prospect
Cobra Resources plc has announced favourable metallurgical test results from its Head Prospect, indicating significant scalability for low-cost in-situ recovery of rare earth elements. Diagnostic tests on composite samples from the Pidinga Formation showed excellent recoveries, comparable to Boland's early-stage results, with a sample composite of 977ppm TREO yielding recoveries of 48% Nd, 47% Pr, 52% Dy, and 54% Tb. The Head Prospect is a large target area approximately 20km south of the Boland Project, and planning is underway for resource-focused drilling to commence in March 2026. These findings support the company's strategy to define a scalable resource across its extensive landholding.

Cobra (LSE: COBR), the mineral exploration and development company advancing a potentially world-class ionic Rare Earth Element ("REE") discovery at its Boland Project ("Boland") in South Australia, is pleased to advise that metallurgical tests on historical pulps from the Head Prospect ("Head") are indicative of significant scalability beyond Boland for low-cost in-situ recovery ("ISR") of ionic heavy REEs.
Head is one of the priority targets included within the recently completed acquisition of tenements from Tri-Star Group Pty Ltd (as announced on 26 January 2026) where large areas of palaeochannel hosted REEs proximal to Boland have been delineated within geological formations that are amenable to ISR.
Diagnostic tests on composite pulp samples recovered from the South Australian core library yielded excellent recoveries from the target horizon - the Pidinga Formation. Recoveries are comparable to early-stage metallurgy results at Boland, where the Company has advanced metallurgical recoveries up to 68% Terbium ("Tb") and 63% Dysprosium ("Dy") through low-cost, low-impact ISR techniques.
Highlights
- A sample composite from drillholes IR275 and IR276 with a composite grade of 977ppm Total Rare Earth Oxide ("TREO") (160ppm Neodymium ("Nd") + Praseodymium ("Pr") and 17ppm Dy +Tb) yielded diagnostic recoveries of:
o 48% Nd, 47% Pr, 52% Dy, 54% Tb and 50% Samarium ("Sm") at pH3 0.5M AMSUL
o Recoveries are roughly five times higher than nearby source rocks (Saprolite and Weathered Granite)
- The Head Prospect is a large (~85km2) target within the Yaninee Palaeochannel located ~ 20km south of the Boland Project
- Planning and land access negotiations are underway to enable step out resource focused drilling at the Head Prospect in March 2026
Rupert Verco, Managing Director of Cobra, commented:
"These results represent another important step in our strategy to define a scalable resource across our significant palaeochannel landholding. Through strategic tenement acquisitions, Cobra now holds over 3,200km of prospective geology.
Metallurgy is key for REE projects, and these results support our thesis for ISR extraction of critical heavy rare earths at scale. Drilling at the Head Prospect next month will target thick ISR recoverable intersections over a significant footprint, representing an exciting opportunity to provide scale to our maiden mineral resource."

Background to Results
Diagnostic leach tests performed by ANSTO laboratories are a first pass process for determining the recovery of REEs under benign acidities. These results have been generated from retained pulp samples from drill holes completed in 1980. Samples were composited from multiple holes to generate sufficient sample. The age of these samples may have impacted the ionic state of REEs. To ensure that the ionic portion was adequately assessed and to evaluate the potential impact of sample age on ionic recovery, samples were benchmarked against source saprolite (clay)/weathered rock samples where recoveries are known to be considerably lower due to colloidal and primary mineral phases. Cobra is including the negligible REE recoveries from nearby clay and saprolite horizons only
to emphasise the excellence of the Pidinga Formation as a potential source of REEs.
Key Points:
Results presented from three composites:
- Composite 1: IR275 (40-42m) & IR276 (44-52m) Coarse Pidinga clays and sands
- Composite 2: IR308A (18-30m) Saprolite to Weathered Granite sourced from below Paleochannel sediments
- Composite 3: IR309 (6-18m) Weathered saprolite away from the palaeochannel
Samples were selected to identify the measurable differences in REE mobility between palaeochannel sediments and underlying source rocks. Results highlight a significant increase in recovery within the permeable Pidinga formation.
These results validate the large 85km2 target area interpreted to be a fluvial flood facies within the Yaninee Palaeochannel stratigraphic sequence (area highlighted in Figure 2).
The Company will execute a step-out drilling strategy commencing adjacent to historical drillhole IR276 that intersected 8m at 1,095 ppm TREO (242 ppm Nd+Pr and 21 ppm Dy+Tb) from 44m including 2m at 2,676ppm TREO (616ppm Nd+Pr and 50ppm Dy+Tb). Drilling at the Head Prospect is expected to commence in March.

Boland Project
Cobra's unique and highly scalable Boland discovery is a strategically advantageous ionic rare earth discovery where high grades of valuable heavy and magnet rare earths occur concentrated in a permeable horizon confined by impermeable clays. Bench scale ISR testing has confirmed that mineralisation is amenable to ISR mining. ISR has been used successfully for decades within geologically similar systems to recover uranium within South Australia. Results of this metallurgical test work support that, with minor optimisation, ISR techniques should enable non-invasive and low-cost production of critical REEs from Cobra's Boland discovery.

| Sampling techniques | · Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. · Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. · Aspects of the determination of mineralisation that are Material to the Public Report. · In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. | Pre 2023 · Historic Rotary Mud drilling targeting paleochannel hosted uranium was completed. Some residue samples were retained in the Tonsley Core Library, downhole geophysical logging was the primary data collected for these holes. · Select historic sample residues over Boland, Head, Stokes and Gillespie were analysed as reported in RNS 1834M (26 April 2024) and August 2025. 2023 Aircore · A combination of 2m and 3m samples were collected in green bags via a rig mounted cyclone.
