GreenX Metals #GRX – Gold and Critical Minerals Portfolio Expanded in Greenland
4th August 2026 / Leave a comment

GreenX Metals Limited (ASX:GRX, LSE:GRX, GPW:GRX, Germany-FSE:A3C9JR) (GreenX or the Company) is pleased to announce the granting of two new exploration licences at the Eleonore North Project (Figure 1) (Eleonore North or Project). The Company has secured exclusive rights to ~1,600 km2 of tenure prospective for reduced intrusion-related gold systems (RIRGS). These new licences complement the Company’s existing licences located 100 km to the north.

HIGHLIGHTS
· Multiple intrusion-related gold targets identified in two new licences covering ~1,600 km². The Company has been exploring the Eleonore North Project for reduced intrusion-related gold systems (RIRGS) since 2024. These new licences build on a growing understanding of this deposit style in this region and secures prospective Caledonian intrusions untested by the RIRGS model.
· Gold assays up to 50 g/t previously reported. Gold-mineralised boulders and quartz veins hosted in granitic intrusions were found in 1975. After a brief site visit in 1983, detailed gold‑scheelite exploration was recommended, but none took place.
· Anomalous gold, silver, tungsten, and arsenic in regional sediment sampling corresponds to target intrusions. Caledonian intrusions and adjacent strata are shedding mineralised material into local streams. Despite strong results from the historic stream sediment sampling program, follow-up gold exploration never took place.
· Extensive evidence of tungsten mineralisation in the form of scheelite from stream sediment sampling. Tungsten is one of the foremost defence materials, widely used in high-strength applications and in armour-piercing ammunition. Tungsten is designated as a strategic raw material by the EU and a critical mineral by the US.
· Fieldwork is now complete, with first results expected this quarter. Reconnaissance sampling and mapping have tested the RIRGS model over the Caledonian intrusions within the new licences. This fieldwork was run in conjunction with exploration at the existing Eleonore North licences (refer to announcement dated 22 July 2026).
· 160 km-long mineralised structural corridor. 60 km to the southeast of the licenced Caledonian intrusions, the Malmbjerg Climax-type molybdenum porphyry deposit straddles the same fault system. 100 km to the north, the structural system passes through the Company’s other licences which host the North Margeries Sb-W and South Margeries W historical deposits and the Noa Pluton Sb-Au-W prospect.
GreenX CEO, Mr Ben Stoikovich, commented: “Securing 1,600 km² of new gold and critical minerals tenure takes our Eleonore North portfolio to approximately 2,100 km² across four licences and gives us exclusive rights to a suite of Caledonian intrusions that have never been tested against the reduced intrusion-related gold model. Documented gold and scheelite anomalism have sat in the public record here since the 1980s without follow-up. We have teams on the ground testing these intrusions this season, with a clear and disciplined program of work through 2026.”
HISTORICAL GOLD RESULTS
In 1975, Nordisk Mineselskab A/S (Nordmine) collected gold-mineralised boulders and veins from the area now covered by the new licences (Table 1). Follow-up exploration involved stream sediment sampling throughout the region in 1979 and 1980. Heavy mineral concentrates from the earlier surveys were analysed in 1983. Gold, scheelite, and other indicator elements were detected within the licence areas. In 1983, geologists visited the site and recommended detailed follow-up exploration for gold and scheelite; however, no further exploration was conducted. Nordmine held an exclusive mineral licence covering 100,000 km2 in East Greenland until its liquidation in 1992.

Geology – GOLD AND CRITICAL MINERALS POTENTIAL
The geological setting of the area is characterised by gneissic basement rocks and Proterozoic metasediments (Figure 2), separated by a major north-south thrust fault extending for 400 km (Figure 4). Thrusting and folding during the Caledonian orogeny juxtaposed the different rock packages. This major structure likely provided conduits for magma and later mineralised fluids. Caledonian intrusions are today found adjacent to fault zones in Eleonore Bay Supergroup sediments.
RIRGS deposits feature a geochemical zonation that changes with distance from the causative intrusion. Metal enrichments proximal to gold mineralisation typically include tungsten (W) and antimony (Sb). Geochemical signatures distal to gold mineralisation include enrichments in silver (Ag), copper (Cu), lead (Pb), and zinc (Zn). At the regional scale, arsenic (As) is a useful indicator for vectoring towards RIRGS-mineralised intrusions.
Regional stream sediment sampling included panning for heavy mineral concentrates. Analysis of the concentrate included counting grains of the tungsten-bearing mineral, scheelite. Figure 3 below shows the scheelite grain count in panned heavy mineral concentrates. There is a strong association between the Caledonian granites and high scheelite grain counts. The spatial association also applies to Au, Ag, Cu, Pb, Zn, and As in panned heavy mineral concentrates.

Figure 3: Scheelite grain count in historical panned heavy mineral concentrate samples.
CRITICAL MINERALS
Tungsten is designated as a Strategic Raw Material by the EU and a critical raw mineral by the US. Tungsten is one of the foremost defence materials, widely used in high-strength applications and ammunition. It is also suitable for high-temperature applications, such as supersonic and hypersonic vehicles. Tungsten’s density makes it ideal for armour-piercing ammunition and counterweights in spacecraft. Commercially, it is mainly used when high strength is required, such as for cutting and construction tools. Global strategic interest in tungsten increased significantly in February 2025, when China announced sweeping export controls targeting tungsten and four other metals used across defence, clean energy and other industries. China’s export controls were announced minutes after an additional 10% tariff on Chinese goods imposed by the U.S. President came into effect.
About 90% of global tungsten comes from Russia, China and North Korea, with China alone accounting for about 80% of the world’s tungsten output. The US has not had domestic tungsten production since 2015.
Work Programs
GreenX’s land tenure at Eleonore North now includes four licences (Figure 4). Prior to the summer fieldwork, the Company re-logged and re-assayed archive drill core from the historical North Margeries Sb-W and South Margeries W deposits. Additionally, historical airborne hyperspectral survey data covering the Margeries deposits was reprocessed (refer to announcement dated 14 May 2026). That data provided new targets which were visited during the field season. Results from the July 2026 fieldwork are expected in the coming months.

GreenX Metals #GRX – 2026 Fieldwork Underway At Eleonore North
22nd July 2026 / Leave a comment

GreenX Metals Limited (ASX:GRX, LSE:GRX, GPW:GRX, Germany-FSE:A3C9JR) (GreenX or the Company) is pleased to announce that fieldwork has commenced at its Eleonore North project in East Greenland (Eleonore North or Project). The exploration program is targeting gold (Au), tungsten (W), and antimony (Sb).
HIGHLIGHTS
· Active exploration underway at the Eleonore North Project, located in East Greenland. The field team are following up high-priority gold, tungsten, and antimony targets, including known prospects and newly generated targets.
· A Reduced Intrusion-related Gold System specialist will evaluate the Noa Pluton prospect as well as untested targets.
· Bulk sampling of tungsten and antimony-mineralised material at North and South Margeries deposits is expected to support scoping study level metallurgical sighter test work.
· Archive core from North and South Margeries deposits was sampled prior to fieldwork commencing and is currently being assayed, with results expected in the coming months.
· Tungsten and antimony are both listed as critical raw materials by the European Union and the United States, with global supply heavily concentrated in China; the Eleonore North Project hosts high-grade occurrences of both in a stable Western jurisdiction.
GreenX’s Chief Executive Officer, Mr Ben Stoikovich, commented: “Greenland is an exciting frontier for GreenX, and this program advances a portfolio of gold, tungsten and antimony targets that has seen very little modern exploration.
Tungsten and antimony are critical raw materials for both the European Union and the United States, and Eleonore North gives us high-grade occurrences of both in a stable Western jurisdiction at a time when supply is heavily concentrated in China. Importantly, the tungsten and antimony mineralisation has a surface expression, which allows us to make rapid progress in expanding the known mineralisation and generating additional targets.
This year we are in the field to advance our existing prospects, including the Noa Pluton gold-antimony target and the North and South Margeries deposits. At the same time, our growing understanding of intrusion-related gold systems in the region has enabled us to identify a number of new targets.”

In relation to the disclosure of visual information and rock chip descriptions, the Company cautions that the images displayed are for general illustrative purposes only, and that the samples displayed, and visual methods of any visible mineral identification and estimation of mineral abundance should not be considered as a proxy for laboratory analysis, and that laboratory analysis is required to determine the grades of the rock chip samples. Visual information also potentially provides no information regarding impurities or deleterious physical properties relevant to valuations. The rock chip samples are point samples (typically 5-15cm in diameter) taken in the field and do not represent true trends or widths of mineralisation. The Company will update the market when the laboratory samples are received. |
Summer Work PROGRAM
Fieldwork at the Eleonore North Project this year covers multiple objectives. At Noa Pluton, a Reduced Intrusion-related Gold System (RIRGS) specialist will conduct mapping and sampling to evaluate antimony and intrusion-related gold potential, and identify potential drill targets. At both North (Sb-W) and South Margeries (W), the team will collect 50 kg to 100 kg bulk samples of mineralised material for scoping study level sighter test work. Recent hyperspectral analysis and prospectivity mapping have also highlighted alteration anomalies along strike and adjacent to both deposits (refer to announcement dated 14 May 2026). These untested hyperspectral anomalies have the potential to be satellite discoveries.
The field team will also visit newly generated RIRGS targets in the broader region for reconnaissance style prospecting, as approved by the Greenland Mineral Resource Authority.

Figure 1: Summer fieldwork is taking place at the Eleonore North licence package on Ymer Island, East Greenland.
Next Steps
North and South Margeries
Rock samples collected during the program will be sent for multi-element analysis while bulk material will undergo metallurgical sighter test work. This test work is designed to provide scoping study level insights into the metallurgy and processing characteristics. Extensional and infill drilling could be warranted if the sighter test work is positive, particularly if the hyperspectral anomalies previously identified along strike are confirmed as antimony and tungsten mineralisation.
All results are expected in the coming months.
Noa Pluton
Results from Noa Pluton will be evaluated by our RIRGS specialist with additional gold and antimony sampling to form the basis for follow-up exploration programs, including the potential to identify drill targets for future field seasons.

GreenX Metals #GRX – Exploration Target highlights potential for large-scale copper-silver project in Germany
28th May 2026 / Leave a comment

GreenX Metals Limited (ASX:GRX, LSE:GRX, GPW:GRX, Germany-FSE:A3C9JR) (GreenX or the Company) is pleased to announce an Exploration Target at the Tannenberg Copper Project (Tannenberg or the Project), in Germany. The estimated range of potential mineralisation in the Exploration Target is: 144 – 279 Mt at 0.9% – 1.4% Cu and 15 – 21 g/t Ag for 1.3 – 3.9 Mt Cu and 69 – 188 Moz Ag.
HIGHLIGHTS
· Exploration Target demonstrates potential for globally significant copper endowment at Tannenberg Copper Project, Germany.
· Exploration Target captures hanging wall and footwall mineralisation above and below the Kupferschiefer shale: a modern view of the deposit that the 1940 historical estimate did not contemplate.
· Validated by Kupferschiefer mining in Poland, where up to 95% of mineable copper at KGHM Polska Miedź S.A’s operations is hosted in the same footwall sandstone and hanging wall limestone units that host the Tannenberg Exploration Target.
· Built on validated historical foundations: Exploration Target builds on the 1940 National Socialist historical estimate area; the 1984 St Joe historical estimate; validation via resampling and logging of 1980’s core by GreenX and digitised archive material collected since August 2024.
· An inflection point for the Project: With the Exploration Target estimated, GreenX now transitions from archive synthesis to active exploration, including accessing historical underground mines for Scoping Study-level metallurgical test work, seismic survey evaluation and commencement of an initial drill program.
Cautionary Statement: The Exploration Target has been reported in accordance with the 2012 edition of the JORC Code (JORC Code). The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource for the reported target areas. It is uncertain if further exploration will result in the estimation of a Mineral Resource.

GreenX’s Chief Executive Officer, Mr Ben Stoikovich, commented: “Today’s Exploration Target at Tannenberg is a result of 18 months of archive data search and synthesis. It also marks an inflection point where we transition from searching for archive data to ramping up our own exploration programs. The modern understanding of the Kupferschiefer system, demonstrated by the scale of Kupferschiefer mining operations in Poland today, shows that economic copper mineralisation extends well beyond the thin shale horizon that historical German exploration focused on. The size of the potential copper endowment at Tannenberg in Hessen, Germany, in the same geological formation of the world-class Polish deposits, justifies continued investment and exploration”.

Figure 1: Outline of the Exploration target and its relationship to previous historical estimates and historical underground mining operations at Tannenberg. Section A-B is shown in Figure 4.
EXPLORATION TARGET
The Exploration Target provides a modern view of the copper potential at Tannenberg. Unlike the 1940 Historical Estimate, which assessed only the thin Kupferschiefer shale horizon (refer to announcement dated 20 October 2025), the Exploration Target captures mineralisation in the hanging wall above and footwall below the shale. This is consistent with the modern understanding of Kupferschiefer deposits as evidenced at KGHM Polska Miedź S.A’s (KGHM) mining operations in Poland. The sections below set out the historical foundations, the modern thickness model and the supporting work that underpin the Exploration Target.
Cautionary Statement: The Exploration Target has been reported in accordance with the JORC Code. The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource for the reported target areas. It is uncertain if further exploration will result in the estimation of a Mineral Resource.

Figure 2: Top-down view of the Exploration Target wireframe at Tannenberg.
From historical mining district to Exploration Target
The Tannenberg Project has a long-documented history of drilling, mining, and estimation work, providing well-defined and historically validated copper-silver mineralisation that underpins today’s Exploration Target.
A 95-hole drilling campaign was completed by the National Socialist Government between 1935 and 1938 across the Richelsdorf Mining District. This dataset formed the geological basis for the construction of three Kupferschiefer copper mines within the Tannenberg licence area, Reichenberg, Wolfsberg and Schnepfenbusch. These mines operated between the late 1930’s and in some cases up to the mid 1950’s. GreenX has digitised and integrated this drillhole database into its geological models (refer to announcement dated 11 September 2025).
The 1940 historical estimate, produced by Mansfeldsche Kupferschieferbergbau AG (Mansfeld AG), is based on a spatially relevant subset of 18 holes from the 95-hole database and established 728,000 tonnes of contained copper* at an average grade of 2.6% copper (in the narrow Kupferschiefer shale only) between the Wolfsberg and Schnepfenbusch mines in the north and the Ronshausen area in the south (see Figure 1). The historical estimate covers mineralisation from a depth of 100 m in the north to 400 m in the southern end area near Ronshausen (refer to announcement dated 20 October 2025).
A later historical estimate from 1984 was produced by St Joe Explorations GmbH (St Joe), based on limited drilling between 1980 and 1984 (refer to announcements dated 2 August 2024 and 28 April 2025). The St Joe historical work estimated (20 October 2025) 169,000 tonnes of contained copper and 6.5 million ounces of contained silver within the small section of zone 3. St Joe assayed wider intersections and found that the mineralisation was up to 3.45 m thick. This is considerably thicker than the narrow Kupferschiefer shale assayed and estimated by Mansfeld AG in 1940. St Joe provided the first modern indication that economic mineralisation extends beyond the Kupferschiefer shale itself.
Cautionary statement for historical estimates: The historical estimates referenced in this announcement are not reported in accordance with the JORC Code. A competent person has not done sufficient work to classify the historical estimates as a mineral resource or ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the historical estimates will be able to be reported as a mineral resource or ore reserve in accordance with the JORC Code.
Modern thickness model
The modern understanding of the Kupferschiefer deposit model, as evidenced at KGHM’s Polish mining operations on the same geological setting as Tannenberg, shows that up to 95% of mineable copper can be hosted in the footwall sandstone and hanging wall limestone, with mineralisation often occurring up to 30 m above and 60 m below the Kupferschiefer shale horizon.
Applying the thick mineralisation concept to the historically defined Tannenberg footprint produces a statistically-derived mineralised thickness of 1.7 m – 3.3 m, compared with the 20 cm – 60 cm (shale-only) thickness used in the 1940 historical estimate. The 1.7 m – 3.3 m thickness is consistent with the wider intercepts confirmed by St Joe in the 1980s and has now been independently validated by GreenX’s resampling of available archived core.
COMPLETION OF ARCHIVE CORE logging and sampling
After relogging a total of 4,389 m of archived core and taking 2,368 new samples, GreenX has now brought its work on the archived core to a close. This program was initiated after the discovery that drill core had been retained in the archives of the Hessisches Landesamt für Naturschutz, Umwelt und Geologie (HLNUG) for over 40 years since drilling. This new logging and sampling has been conducted in accordance with industry standard practices and has facilitated the estimation of the Exploration Target ranges. In addition to the validation of the historical copper and silver grades around the historical mining areas (see announcement date 20 November 2025), the data has demonstrated that the copper and silver mineralisation persists many kilometres away from the historical copper mines (Wolfsberg, Schnepfenbusch, and Reichenberg).

Figure 3: Location map of 1980s Archive drillholes recently logged and assayed by GreenX.
Upcoming and ONGOING Work Programs
GreenX is advancing a coordinated suite of exploration activities which will test the validity of the Exploration Target identified at Tannenberg, including:
· Mineralogical and desktop metallurgical analysis of material collected from archive core – Q2 2026;
· Accessing historical underground mines for scoping study-level metallurgical test work, chip sampling, as well as mapping and surveying for 3D modelling – 2H 2026;
· Collation and digitisation of historical geological, mine development, and production data – ongoing;
· Analysis of the use of seismic surveys to aid future drilling campaigns including collecting petrophysical measurements for seismic forward modelling – Q2 2026;
· Seismic survey, if appropriate – commencement H2 2026; and
· Initial drill program – commencement late 2026.
Exploration target: Drillhole database audit and verification
GreenX logged, sampled, and assayed available archive core at Tannenberg (Archive). The work was done by Palsatech in a specialist logging facility in Sweden. MSA Mining Consulting UK Ltd’s (MSA-UK) independent competent person visited the facility while Archive core was being processed. All intercepts with significant Cu-Ag mineralisation were drilled by St Joe’s during their 1980s exploration drilling.
The 1930s National Socialist drillhole database was compiled by GreenX geologists, transcribed from hard copy, historical records. An independent audit and verification of the data against these records was not undertaken by MSA-UK. Given that the intention is to declare an Exploration Target, this is not considered a material risk by MSA-UK.
Data validation was undertaken during the import routine in the form of correcting issues such as from/to errors and preparing the data in a format that can readily be imported into three-dimensional modelling software.
Exploration target: Geological Modelling
A geological model was constructed in Leapfrog Geo. Although a number of mapped faults cross the area, only five, relevant fault structures were considered in the model (Figure 1). Four stratigraphic units, namely the Basement, Rotliegend, Zechstein and Buntsandstein were modelled. Due its narrowness and the lateral scale of the model, which spans several kilometres, the Kupferschiefer layer was modelled only as the contact between the Rotliegend and Zechstein. Displacement by faulting is data driven, where the relative position of the stratigraphic units on either side of the fault determines the vertical displacement (Figure 4).
A conceptual mineralisation model was constructed from the drillhole data using a threshold value of 0.30 % Cu. This value was based on the log-probability plot for the combined dataset (Figure 5), which shows a break in the grade population around this threshold. This is a reasonable value, as it incorporates mineralisation in the footwall Rotliegend, the Kupferschiefer and the hanging wall Zechstein.
In addition to the grade threshold, a minimum thickness of 1.5 m was applied during the modelling process, based on regulation and practise at copper mines in Poland Where necessary, low-grade samples falling below the threshold were incorporated into the mineralised zone to achieve the minimum thickness, provided the full composite grade satisfied the threshold value. Due to the sampling bias in the National Socialist dataset, only data generated from 1980s era drilling was used to constrain the thickness of the mineralisation model.
However, the National Socialist data was used to infer lateral continuity of the mineralisation. In order to not overstate tonnages, the mineralisation was truncated against the modelled faults, extrapolated no more than 500 metres beyond the data and limited within the Tannenberg license boundary. Furthermore, mined out areas where discounted from the mineralisation model.
Three areas were considered, a larger area to the southwest, Zone 3, where the model is informed by a combination of Archive and National Socialist data and two smaller areas across fault boundaries towards the northeast, Zone 1 and Zone 2, as shown in Figures 1 and 2.
Zone 3 has an areal extent of approximately 6 km by 3.5 km. The mineralisation thins out towards the southwest and northwest where drillholes tend to have low-grade copper intercepts that do not meet the minimum thickness criteria, therefore being excluded from the model. Towards the northeast, the mineralisation terminates against a northwest-southeast running fault. Zone 2 is located adjacent to Zone 3 on the northeast side of the bounding fault, with an extent of 3.1 km in the northwest to southeast direction and 2.8 km in the northeast direction. Zone 1 is narrow, bound by two parallel faults and has an areal extent of 1.8 km by 900 m. Both Zones 1 and 2 have been restricted in extent from known mined out areas to the north.

Exploration target: GRADE AND THICKNESS ESTIMATION
As per the requirements for declaring an Exploration Target, grade and tonnages need to be expressed in ranges. The lateral extent of the mineralised zones is restricted by structural features and the license boundary, with little room for extrapolation. Therefore, tonnage ranges are given by assuming a variable thickness of the mineralised zones, which is supported by the dataset. Only the Archive data was used to derive grade and thickness ranges as it provides a complete vertical profile through the mineralised zone. Samples captured within the Zone 3 mineralised area were selected and composited to full thickness, resulting in ten composite samples. Full thickness composites were used to derive both grade and thickness ranges for the Exploration Target because this approach minimises the variability of the smaller sample intervals, thus reducing sampling bias and avoiding artificially inflated grades when estimating grade ranges. An additional drillhole, Ro 45, located to the north outside of the area of interest was also used to supplement the data. This hole was included as it is the only Archive drillhole outside of the modelled area that meets the minimum criteria and was incorporated to support the statistical analysis given the limited number of available data points. The remaining Archive holes were not considered as they fall outside the modelled extents of the mineralisation.
The list of drillholes, copper and silver grades and accumulated grades are shown in Table 2 below.

An attempt was made to derive grade and thickness ranges using a two-sided confidence interval method on the dataset however this statistical approach resulted in very narrow ranges which are not representative of the inherent variability of the data. Therefore, the interquartile range (IQR) was used instead to define the lower and upper grade and thickness ranges. In this case, the IQR is considered appropriate for this small dataset, as it provides a measure of dispersion around the median, thus reducing the influence of grade and thickness outliers. The resultant ranges are therefore a more realistic representation of the dataset (Table 4).

Density data is not currently available for the project, therefore average densities were sourced from available literature (Taylor, R.D and Anderson, E.D., 2010). An assumption was made for a three metre thick mineable width with the Kupferschiefer shale representing 0.40 m of the total thickness, while the Zechstein and Rotliegend have assumed thicknesses of 1.30 m. Average densities were assigned as shown in Table 5.

A weighted, average relative density for the three-metre-thick mineralised zone is calculated as 2.62 t/m3.
Exploration target: ESTIMATION
According to the JORC Code, an Exploration Target is “a statement or estimate of the exploration potential of a mineral deposit in a defined geological setting where the statement or estimate, quoted as a range of tonnes and a range of grade (or quality), relates to mineralisation for which there has been insufficient exploration to estimate a Mineral Resource”. The code states that the terms “Resource” and “Reserves” must not be used in this context to refer to the potential quantity and grade of the target.
The base case for the mineralisation is based on the areal extent of copper mineralisation, above a threshold of 0.30 % Cu, that meets a minimum thickness criteria of 1.50 m. Surfaces created in Leapfrog Geo were used to model lateral continuity of the mineralised zones and derive areas for three zones. Thickness ranges were derived from the Archive data and using an assumed average density of 2.62 t/m3, lower and upper ranges of tonnages were calculated as shown in Table 6.

The Exploration Target for the combined Tannenberg mineralisation is shown in Table 9. As per the JORC Code, it must be stated that the potential quantity and grade of the Exploration Targets are conceptual in nature, that there has been insufficient exploration to estimate Mineral Resources and that it is uncertain if further exploration will result in the estimation of Mineral Resources.

GreenX Metals #GRX – Interim Financial Report for the Half-Year Ended 31 December 2025
12th March 2026 / Leave a comment
The Directors of GreenX Metals Limited present their report on the Consolidated Entity consisting of GreenX Metals Limited (Company or GreenX) and the entities it controlled during the half-year ended 31 December 2025 (Consolidated Entity or Group).
OPERATING AND FINANCIAL REVIEW
Operational Highlights
Highlights during and subsequent to the half year end include:
· German Project – Tannenberg Copper Project
· Historical estimate:
o During the period, the Company announced an historical estimate of 728,000 tonnes contained copper (1,605 Mlbs) at an average grade of 2.6% copper at part of the Tannenberg Copper Project (Tannenberg or Project)
§ Estimate based on a 1935-1938 National Socialist Government drilling campaign across four zones: Ronshausen, Hönebach, Wolfsberg and Schnepfenbusch
§ Drilling targeted the thin Kupferschiefer horizon only
§ Focused only on copper and did not include by-product metals
§ A total of 250,000 tonnes of contained copper was omitted in the historical estimate to account for areas where surface features might prevent mining
o Independent company St Joe Exploration GmbH conducted limited drilling between 1980 and 1984, further validating the 1940 historical estimate
§ Drilling focused on only 28% of the Ronshausen zone but included by-product silver
§ Drilling identified up to 3.45m thick mineralisation straddling the Kupferschiefer and the limestone hanging wall and sandstone footwall above and below the Kupferschiefer
§ 1984 historical estimate shows consistent grades of 2.1% copper plus 25 g/t silver with 169,000 tonnes of contained copper and 6.5 million ounces of silver
o Exploration upside potential under modern interpretation: St Joe Exploration confirmed thicker widths of copper and silver mineralisation at Ronshausen, and more may exist up to 30m above and 60m below the Kupferschiefer in the limestone hanging wall and sandstone footwall
o Cautionary statement: The historical estimates in this announcement are not reported in accordance with the JORC Code (2012) (JORC Code). A competent person has not done sufficient work to classify the historical estimate as a mineral resource or ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the historical estimate will be able to be reported as a mineral resource or ore reserve in accordance with the JORC Code
· Modern Assays Validate Historical Copper Grades:
o High-grade copper intercepts confirmed: Modern assays from archived drill cores confirm historical grades with intercepts of 1.0-3.7m at 0.7-2.7% copper and 10-55 g/t silver
§ Ro 23: 1.5m at 2.7% copper and 55 g/t silver
§ Ro 45: 2.4m at 1.4% copper and 18 g/t silver
§ Ro 25: 1.0m at 2.0% copper and 41 g/t silver
§ Ro 17: 1.3m at 1.2% copper and 24 g/t silver
§ Ro 15: 3.7m at 1.2% copper and 17 g/t silver
§ Ro 38: 1.8m at 0.7% copper and 15 g/t silver
o Mineralisation thicker than 1940 historical estimate: New intercepts demonstrate widths of 1.0-3.7m, significantly exceeding the maximum thickness used in the 1940 Historical Estimate (refer to announcement dated 20 October 2025)
o First Modern Assays for over 40 years: Results from re-sampling of 1980s drill core from holes located up to 12km apart show comparable or higher grades and thicker intercepts than original analysis, validating historical work and demonstrating resource upside and scale potential
o Confirms GreenX epigenetic model: Results confirm that mineralisation extends beyond the narrow Kupferschiefer shale horizon into the footwall and hanging wall, consistent with KGHM’s Polish operations (589,000tpa copper production) located on the same basement architecture
o Quality assured program: All samples meet strict QAQC standards, including >90% core recovery, with analysis by ISO/IEC 17025 accredited laboratory
o Significant program ahead: In 2026, GreenX intends to progress an integrated program to support future JORC Code reporting, including, continued reprocessing/interpretation of historical geophysics and datasets, and advancing plans for drilling to verify historical estimates and prove up extensions to known mineralisation to underpin a future Mineral Resource

· Tannenberg Copper Project Acquisition:
o The Company announced the completion of the acquisition of 90% of Group 11 Exploration Gmbh (Group 11 or Vendor) which holds the Tannenberg exploration licences
o Since signing the Joint Venture and Earn-in Agreement (JVA) in 2024, the Project area has expanded seven-fold to cover approximately 1,900 km², comprising the Tannenberg 1 and Tannenberg 2 exploration licences
Greenland – Eleonore North Project
· Targeting Gold, Tungsten & Antimony:
o Outcropping gold and high-grade antimony mineralisation now confirmed at the Noa Prospect within the Eleonore North Project in East Greenland (Eleonore North or ELN)
o High-grade tungsten and antimony mineralisation also identified in Historical Estimate at the Margeries Prospects within the Eleonore North project
§ 83kt of mineralised rock with a mean grade of 4.6% Sb at North Margeries
§ 58kt of mineralised rock grading at 3.2% W at South Margeries
§ 32kt of mineralised rock grading at 1% W at North Margeries
o Potential to identify large scale deposits in new underexplored province with gold mineralisation associated with quartz veining at surface over a length of up to 15 km
o Field activities initially focusing on the shallow gold and high-grade tungsten and antimony potential are currently being finalised for 2026
o Cautionary statement: The Historical Estimates in this announcement are not reported in accordance with the JORC Code. A competent person has not done sufficient work to classify the Historical Estimate as a mineral resource or ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the Historical Estimate will be able to be reported as a mineral resource or ore reserve in accordance with the JORC Code

Figure 2: Overview of gold and critical metal prospects within Eleonore North.
· Eleonore North Project 2026 Work Program:
o GreenX will finalise the 2026 exploration program to define and prioritise drill targets, including processing the historical hyperspectral survey and undertaking field mapping/sampling at Noa to ground-truth “reduced intrusion-related gold system” (RIRGS) targets; and at Margeries, collecting bulk samples for W/Sb metallurgical sighter test work, reviewing archived core for re-analysis/metallurgical sampling, and reprocessing historic geophysics/hyperspectral data alongside field mapping to generate drill targets
· Singapore Court Dismissed Poland’s Set-Aside Application
o The Singapore International Commercial Court of the Republic of Singapore (Singapore Court) rejected, in its entirety, the Republic of Poland’s (Poland) application to set aside the Energy Charter Treaty (ECT) award, thereby upholding GreenX’s previously announced right to compensation under the ECT
o As previously advised, in October 2024, GreenX was awarded approximately £252 million (A$519 million / PLN 1.2 billion) in compensation and interest in the Australia-Poland Bilateral Investment Treaty (BIT) award after the Tribunal unanimously held that Poland breached its obligations under the BIT and ECT
o At the time, approximately £183 million (A$378 million / PLN 900 million) was awarded pursuant to the ECT (with payments under one award offset against the other)
o In 2025, Poland lodged a request to set-aside the ECT award in the Singapore Court (having also lodged a request to set-aside the BIT award in the courts of England and Wales in late 2024). The hearing for the ECT set-aside was held in the Singapore Court in July 2025
o Subsequent to the end of the period, the Singapore Court issued a judgment whereby it has rejected, in its entirety, Poland’s application to set aside the ECT award
o The Company has also been awarded A$1.6 million by the Singapore Court that is to be paid by Poland to reimburse the Group for legal costs associated with defending Poland’s failed ECT set-aside motion
o Additional interest of approximately £17 million (A$34 million / PLN 83 million) has already accrued from when the Award was made in October 2024 to end of December 2025 and will continue to compound annually until full and final payment by Poland
o The Company is currently preparing enforcement activities following the Singapore Courts rejection of Poland’s ECT set-aside motion
o In February 2026, Poland appealed the Singapore Courts ECT set-aside rejection. It is expected that this appeal will be dealt with expeditiously by the Singapore appeal court with Poland then having no further rights of appeal through the Singapore courts
· Corporate
o Subsequent to the period, the Company announced that it had completed a placement to raise gross proceeds of approximately A$13.6 million which will be be used for exploration and development activities at the Company’s Tannenberg Copper Project in Germany (Tannenberg) and at Eleonore North, and general working capital, including costs in relation to the Company’s ongoing arbitration proceedings against Poland
Operations
Tannenberg Copper Project (Germany)
Tannenberg is a large scale, relatively shallow and potential high-grade copper brownfields exploration project that is strategically located in the heartland of German industry.
Copper is currently recognised as a strategic raw material by the European Union.
Prior to closure in the 1950’s, the Richelsdorf mines produced 416,500 tonnes of copper and 33.7 million ounces of silver from Kupferschiefer type deposits. These historic mines consisted of shallow underground workings originally accessed from surface outcrops.
Kupferschiefer style deposits are a well-known and prolific subtype of sediment-hosted copper deposit that are the second most prevalent source of copper production and reserves in the world and have been historically mined in Germany and are still mined in Poland.
Germany has been a significant mining jurisdiction in the past and continues its mining tradition, including the K+S potash mines which operate 4 km away from the license area and are located in the State of Hesse.

Figure 3: Tannenberg is located in the industrial centre of Europe within the Basal Zechstein trend
(brown shading)
Tannenberg Copper Project Acquisition
During the period, the company announced that completion occurred following exercise of its option to acquire 90% of Group 11, the company which holds the Tannenberg exploration licences.
Since signing the Agreement in 2024, the licence area has expanded seven-fold to cover approximately 1,900 km², comprising the Tannenberg 1 and Tannenberg 2 exploration licences (announced on 28 April 2025). The acquisition of the completed by the Company applies to the entire expanded Project area.
Modern Assays Validate Historical Copper Grades
During the period, the Company announced assay results from its historical core logging and sampling program at Tannenberg. These results further validated historical exploration data from the 1980s and confirmed that mineralisation widths are thicker than those used in the 1940 Historical Estimate (refer to announcement dated 20 October 2025).
The Richelsdorf Mining District has been subject to significant historical drilling, with a 95-hole drilling program completed in the mid-1930s by the National Socialist Government. GreenX discovered the drill database from this program in various German archives (refer to announcement dated 11 September 2025). Subsequent exploration from the 1970s onwards included copper and oil exploration, with archived core available for modern analysis. Historical analysis of the archived cores in the program, typically focused on a narrow 5m-wide interval across the Kupferschiefer shale.
Historical exploration was constrained by the prevailing geological model, which assumed copper mineralisation was syngenetic and restricted to the thin Kupferschiefer shale. This limitation meant sampling focused on a narrow interval, typically only 5m around the Kupferscheifer horizon, rather than the up to 90m intervals that characterise economic Kupferschiefer deposits in Poland today.
The modern understanding of Kupferschiefer copper systems, as demonstrated by KGHM Polska Miedz (KGHM) operations in Poland, supports GreenX’s epigenetic model. KGHM produces over 589,000 tonnes of copper per annum (Source: KGHM Annual Report 2024) from deposits similar to those at Tannenberg, with mineralisation often occurring up to 30m above and 60m below the Kupferschiefer shale horizon. KGHM’s operations are located on the same basement architecture as the Tannenberg Project.
2025 Core Sampling Results
The results announced in this report are historical core assay results where over 90% of historical core was available over the target sample interval that form part of the program. The results have confirmed that mineralisation is present in widths which are thicker than just the narrow Kupferschiefer shale. In this program, mineralisation widths range from 1.0 to 3.7 meters. These results show that the mineralisation is thicker than only the Kupferschiefer strata included in the 1940 Historical Estimate. Not only do these results confirm that the analyses performed by St Joe in the 1980s were accurate, but also that the concept of syngenetic mineralisation restricted to the narrow Kupferschiefer is geologically incorrect. The results are consistent with the expectation that considerably more mineralisation exists at the Tannenberg project than reflected in the 1940 Historical Estimate, which was restricted to reporting mineralisation in the Kupfershiefer shale only (refer to announcement dated 20 October 2025).

Most holes for the six sets of assay results reported are located in the Ronshausen area, where the 1940 Historical Estimate was subsequently validated by the 1980’s Historical Estimate produced by St Joe (refer to announcement dated 20 October 2025). One of the assay results is from hole Ro 45 located near Nentershausen to the north of the area covered by the 1940 Historical Estimate, in the vicinity of the Reichenberg mine.

Figure 4: The locations of the historical estimates and the reported assay results from the initial batch of six holes where greater than 90% of the historical core over the target interval was available from the archived core.
Historical Estimate
During the period, the Company announced that it had identified a historical estimate of 728,000 contained tonnes of copper (1,605 Mlbs) at an average grade of 2.6% copper at Tannenberg from 1940 (1940 historical estimate). The 1940 historical estimate was produced by the German company Mansfeldsche Kupferschieferbergbau AG (Mansfeld AG) and is based on the 95-drill hole exploration campaign carried out during the late 1930s (refer to further discussion below).
In addition, a later historical estimate from 1984 was produced by St Joe Exploration GmbH (St Joe), which covers a small part of the same area as the 1940 historical estimate (St Joe’s historical estimate).
The St Joe’s historical estimate is based on limited drilling between 1980 and 1984 (refer to announcements dated 2 August 2024 and 28 April 2025). St Joe’s historical estimate provides further validation for the 1940s historical estimate.
Cautionary statement: The historical estimates in this announcement are not reported in accordance with the JORC Code. A competent person has not done sufficient work to classify the historical estimate as a mineral resource ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the historical estimate will be able to be reported as a mineral resource ore reserve in accordance with the JORC Code.
1940 Mansfeld Historical Estimate
The 1940 historical estimate was calculated by Mansfeld AG according to the relevant German standards applicable during that time. The 1940 historical estimate is based on 18 holes from the 95-hole database generated during the 1935 to 1938 drilling campaign. The original archive document established 728,000 tonnes of contained copper at an average grade of 2.6% copper between the Wolfsberg and Schnepfenbusch mines in the North and the Ronshausen area in the South (Figure 3). The historical estimate covers mineralisation from a depth of 100m in the North to 400m in the Southern end area near Ronshausen.
The 1940 historical estimate covers only the narrow width Kupferschiefer shale mineralisation, which is notable due to the mistaken belief at the time that copper was only present in the distinctive Kupferschiefer shale. Later exploration campaigns have found mineralisation over much wider thicknesses (see 1984 St Joe’s historical estimate section below). This is consistent with GreenX’s exploration hypothesis that historical exploration was mainly based on an outdated deposit model that focused on the 20-60 cm-thick Kupferschiefer shale horizon. The modern understanding of the Kupferschiefer deposit model now shows that up to 95% of mineable copper can be hosted in the footwall sandstone and hanging wall limestone, as evidenced at KGHM Polska Miedź S.A’s Polish mining operations.

It is also noteworthy that the 1940 historical estimate did not include by-product silver mineralisation. The majority of the mineralisation (463,000 tonnes of contained copper) was found to be present in the Ronshausen region, with gradually decreasing amounts to the North, where the historical mining is to be found (refer Table 2 below).

Cautionary statement: The historical estimates in this announcement are not reported in accordance with the JORC Code. A competent person has not done sufficient work to classify the historical estimate as a mineral resource ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the historical estimate will be able to be reported as a mineral resource ore reserve in accordance with the JORC Code.
The 1940 historical estimate data provides a good level of transparency with regard to the input data and the calculation methods used. The estimation resulting from the drill hole data was cross-checked by Mansfeld AG against the production grades at the Wolfsberg and Schnepfenbusch mines, which were operating in the area at the time of 1940 historical estimate.
The comparison was favourable, and hence the assays from the exploration holes were used. GreenX has reviewed original records covering 17 of the 18 holes (~95%) used for the historical estimation and found no discrepancies.
Mansfeld AG made specific adjustments as part of the 1940 historical estimate to account for sterilisation. A total of 250,000 tonnes of contained copper was omitted to account for areas where surface features might prevent mining. Mansfeld AG also estimated that a further 23,793 tonnes of contained copper had already been extracted by mining at Wolfsberg and Schnepfenbusch (at a production grade of 2.2% Copper). This amount was then subtracted from the historical estimate, as presented in the original source document (refer Table 2 above).
1984 St Joe’s Historical Estimate
Part of the Ronshausen zone of the 1940 historical estimate was drilled by St Joe Exploration during the 1980’s, resulting in recognition of the St Joe’s historical estimate more than 40 years later. Of the many holes drilled by St Joe, a total of 14 holes were used in the estimate of 169,000 of contained copper and 6.5 million ounces of contained silver. The St Joe’s work estimated grades of 2.1 % copper and 25 g/t silver at typical depths between 290 and 370m (Figure 4).
St Joe benefited from both technological advancements and enhanced geological understanding in the 40 years following the work by Mansfeld AG. Consequently, St Joe assayed wider intersections and found that the mineralisation was up to 3.45m width. The historical estimate was calculated using thicknesses of between 1.5 to 2m, considerably thicker than the narrow Kupferschiefer assayed and estimated by Mansfeld AG in 1940.

Figure 6: Map showing the drill holes and locations of the Ronshausen zone of the 1940 historical estimate and the relative location of the 1984 St Joe’s historical estimate
Given the increased mineralisation thickness covered by St Joe and the fact that the drilling covered only 28% of the Ronshausen zone, the St Joe’s historical estimate further validates the 1940 historical estimate. The identification of much thicker mineralisation and contained silver also points to considerable exploration upside over all five mineralisation zones covered by the 1940 historical estimate.
Cautionary statement: The historical estimates in this announcement are not reported in accordance with the JORC Code. A competent person has not done sufficient work to classify the historical estimate as a mineral resource or ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the historical estimate will be able to be reported as a mineral resource or ore reserve in accordance with the JORC Code.
Ongoing Exploration Work Programs at Tannenberg
With the acquisition of Tannenberg now complete, GreenX continues to advance a coordinated suite of exploration activities at the Project, which includes:
· Logging, assaying, and hyperspectral scanning of historical core (ongoing);
· Reprocessing and analysis of historical geophysical data (ongoing);
· Collation of historical geological, mine development, and production data (ongoing); and
· Planning for future drilling to verify the historical datasets and expand on the historical estimate in order to establish a mineral resource estimate in accordance with the JORC Code.
Eleonore North Gold and Antimony Project
GreenX has previously announced that high grade antimony mineralisation had been identified at its Eleonore North project in Greenland (Eleonore North or ELN), based on historical results recently released by the Geological Survey of Denmark and Greenland (GEUS). The historical results indicate the potential for a high-grade antimony-gold mineral system at ELN. Antimony prices have been on a rapid uptrend since China announced antimony export controls from 15 September 2024, with antimony prices in the US now having increased to over US$60,000/t from US$18,300/t.
Noa Prospect – potentially large-scale bulk tonnage gold/antimony
The Noa Prospect is located within the ELN Project on exploration licence MEL 2023-39 and has the potential to host a RIRGS, analogous to large bulk-tonnage deposit types found in Canada including Donlin Creek, Fort Knox and Dublin Gulch.
· Gold and antimony mineralisation documented at the high-priority Noa Prospect within Eleonore North
· Geophysical “bullseye” anomaly 6 km wide co-incident with elevated gold and antimony mineralisation from historical geochemical sampling
· Anomalous gold mineralisation associated with quartz veining exposed at surface over a length of up to 15 km
· Historical individual specimens grading up to 23% antimony (Sb), and other samples up to 4g/t gold (Au)
· Previously reported historical data confirmed the presence of gold and high-grade antimony in outcropping veins at ELN, including:
o 14 m long chip sample grading 7.2% Sb and 0.53g/t Au
o 40 m chip line with a length weighed average of 0.78g/t Au
· Antimony mineralisation has been identified along a ~4km trend in veins and structures, that broadly aligns with previously identified gold veining at surface within a 15 km trend
Eleonore North hosts antimony and gold-bearing veins in an area sitting above a geophysical anomaly at Noa interpreted to be a pluton (Figure 5). A passive seismic survey in 2023 showed evidence for multiple blind intrusions rising to just beneath the surface, and processing of results in 3D identified 1-2 km wide elongated plutons, which are priority targets.

Figure 7: Historical results show evidence for high-grade antimony and gold mineralisation above the interpreted pluton at Noa.
Margeries Prospects – high grade tungsten and antimony Historical Estimate
The Margeries Prospects are also located within the ELN Project on the exploration licence MEL 2018-19 where high grade tungsten and antimony mineralisation has been identified as historical estimates:
· 83 kt of mineralised rock with a mean grade of 4.6% Sb at North Margeries
· 58.1 kt of mineralised rock grading 3.2% W at South Margeries
· 32 kt of mineralised rock grading 1% W at North Margeries
Over 2,000 m of historical drilling has been completed, with core still available in Greenland, together with scoping-level metallurgical test work on tungsten. GreenX will revisit and re-analyse the historical drilling and metallurgical data with an aim to report in accordance with the JORC Code.
Cautionary statement: The Historical Estimate referred to above are not reported in accordance with the JORC Code. A competent person has not done sufficient work to classify the Historical Estimate as a mineral resource or ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the Historical Estimate will be able to be reported as a mineral resource or ore reserve in accordance with the JORC Code.

Figure 8: Location map for the Margeries Prospects within MEL 2018-19.
Next steps for Eleonore North (2026 program planning)
Over the coming months, GreenX will finalise the ELN exploration program for 2026 to further define and prioritise potential drill targets, including:
Noa Prospect:
· Process the historical hyperspectral survey
· Field mapping and sampling to ground-truth RIRGS targets and identify drill targets
Margeries Prospects:
· Collect bulk sample material for both tungsten and antimony metallurgical sighter test work
· Inspect the archive core with a view to obtaining samples for re-analysis and metallurgical sighter test work
· Reprocessing of historic geophysics/hyperspectral data and field mapping to identify drill targets
ARCTIC RIFT COPPER PROJECT (ARC) AND JOINT VENTURE
Given the prospectivity and focus on Tannenberg in Germany and at Eleonore North, and following a review of its portfolio of projects and the most efficient and effective use of the Company’s resources, GreenX has agreed to wind up the ARC joint venture and as a result it has fully impaired the exploration and evaluation asset. The Company is currently in the process of relinquishing the ARC exploration licence held in Greenland and winding up the joint venture entity which is now expected to be completed in the second half of 2026.
Singapore Court Dismisses Poland’s Set-Aside Application
Subsequent to the period, the Company announced that the Singapore Court rejected, in its entirety, Poland‘s application to set aside the ECT award, thereby upholding GreenX’s previously announced right to compensation under the ECT.
In January 2025, Poland lodged a request to set-aside the ECT award in the Singapore Court challenging jurisdictional aspects of the ECT award and alleged procedural unfairness in the Tribunal’s decision on damages.
GreenX advised that the Singapore Court has now issued a judgment whereby it has rejected, in its entirety, Poland’s application to set aside the ECT award.
The Company has also been awarded A$1.6 million by the Singapore Court that is to be paid by Poland to reimburse the company for legal costs associated with defending Poland’s failed ECT set-aside motion.
A redacted judgment has been released by the Singapore Court. The Company intends to bring the judgment to the attention of the English courts as part of the BIT set-aside proceedings. In February 2026, Poland applied to the Court of Appeal of the Republic of Singapore to appeal the Singapore Courts rejection of its ECT set-aside motion. It is expected that this appeal will be dealt with expeditiously by the Singapore appeal court with Poland then having no further rights of appeal. The threshold to succeed on a set aside motion in either the Singapore or English courts is very high, with the courts rejecting set-aside applications in the vast majority of cases.
The Company is currently preparing enforcement activities following the Singapore Courts rejection of Poland’s initial ECT set-aside motion.
The Company will continue to defend its awards and update the market in line with its continuous disclosure requirements.
Corporate
Subsequent to the period, the Company announced that it had successfully completed a bookbuild and secured firm commitments for a placement to raise gross proceeds of approximately A$13.6 million.
The net proceeds from the placement will be used for exploration and development activities at Tannenberg and Eleonore North, and general working capital, including costs in relation to the Company’s ongoing arbitration and set-aside proceedings against Poland.
Directors
The names and details of the Company’s Directors in office at any time during the half-year and until the date of this report are:
Directors:
Mr Ian Middlemas Chairman
Mr Benjamin Stoikovich Director and CEO
Mr Garry Hemming Non-Executive Director
Mr Mark Pearce Non-Executive Director
Unless otherwise shown, all Directors were in office from the beginning of the half-year until the date of this report.
Results of Operations
The net loss of the Consolidated Entity for the half-year ended 31 December 2025 was $8,212,005 (31 December 2024: $2,092,947). Significant items contributing to the current half-year loss and the substantial differences from the previous half-year include to the following:
(i) Arbitration related expenses of $1,017,518 (31 December 2024: $723,787) relating to the ongoing claim against Poland including set-aside defence costs (which are currently unfunded). This has been offset by the arbitration funding income of nil (31 December 2024: $251,593);
(ii) Exploration and evaluation expenses of $824,077 (31 December 2024: $338,762), which is attributable to the Group’s accounting policy of expensing exploration and evaluation expenditure incurred by the Group subsequent to the acquisition of rights to explore and up to the commencement of a bankable feasibility study for each separate area of interest;
(iii) Non-cash share-based payment expense of $587,011 (December 2024: $81,000) due to incentive securities issued to key management personnel and other key employees and consultants of the Group as part of the long-term incentive plan to reward key management personnel and other key employees and consultants for the long-term performance of the Group;
(iv) Business development expenses of $272,773 (31 December 2024: $314,855) which includes expenses relating to the Group’s review of new business and project opportunities; including business development costs for the Tannenberg transaction in the prior period, plus also investor relations activities during the six months to 31 December 2025 including public relations, digital marketing, and business development consultant costs;
(v) Exploration and evaluation asset impairment of $4,415,000 (31 December 2024: nil), relating to the impairment of the exploration and evaluation asset previously recognised in relation to the ARC project as a result of the Company agreeing to wind up the ARC joint venture and relinquish the exploration licence in Greenland; and
(vi) Interest income of $76,189 (31 December 2024: $141,391) earned on cash and cash equivalents held by the Group.
Financial Position
At 31 December 2025 the Company had net assets of $6,819,371 (30 June 2025: $14,322,747) a decrease of approximately 53% compared with 30 June 2025. This is largely attributable to expenditure on the arbitration related expenses and decrease of the exploration and evaluation asset following the impairment of ARC. Subsequent to the end of the period, the Company completed a placement to raise gross proceeds of approximately $13.6 million. Following the completion of the placement, the Company had cash reserves of approximately $14.6 million.

GreenX Metals #GRX – Quarterly Activities Report December 2025
30th January 2026 / Leave a comment
GreenX Metals Limited (ASX:GRX, LSE:GRX, GPW:GRX, Germany-FSE:A3C9JR) (GreenX or the Company) is pleased to present its Quarterly Activities Report for the period during and subsequent to 31 December 2025.
HIGHLIGHTS
· CORPORATE
o Subsequent to the quarter, the Company announced that it had successfully completed a bookbuild and secured firm commitments for a placement to raise gross proceeds of approximately A$13.6 million.
· GERMANY – TANNENBERG COPPER PROJECT
· HISTORICAL ESTIMATE:
o During the quarter, the Company announced an historical estimate of 728,000 tonnes contained copper (1,605 Mlbs) at an average grade of 2.6% copper on part of the Tannenberg licence area
§ Estimate based on a 1935-1938 National Socialist Government drilling campaign across four zones: Ronshausen, Hönebach, Wolfsberg and Schnepfenbusch
§ Drilling targeted the thin Kupferschiefer horizon only
§ Focused only on copper and did not include by-product metals
o Independent company St Joe Exploration GmbH conducted limited drilling between 1980 and 1984, further validating the 1940 historical estimate
§ Drilling focused on only 28% of the Ronshausen zone but included by-product silver
§ Drilling identified up to 3.45m thick mineralisation straddling the Kupferschiefer and the limestone hanging wall and sandstone footwall above and below the Kupferschiefer
§ 1984 historical estimate shows consistent grades of 2.1% copper plus 25 g/t silver with 169,000 tonnes of contained copper and 6.5 million ounces of silver
o Exploration upside potential under modern interpretation: St Joe Exploration confirmed thicker widths of copper and silver mineralisation at Ronshausen, and more may exist up to 30m above and 60m below the Kupferschiefer in the limestone hanging wall and sandstone footwall
o Cautionary statement: The historical estimates in this announcement are not reported in accordance with the JORC Code (2012) (JORC Code). A competent person has not done sufficient work to classify the historical estimate as a mineral resource or ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the historical estimate will be able to be reported as a mineral resource or ore reserve in accordance with the JORC Code
· MODERN ASSAYS VALIDATE HISTORICAL COPPER GRADES:
o High-grade copper intercepts confirmed: Modern assays from six (of 47) archived drill cores confirm historical grades with intercepts of 1.0-3.7m at 0.7-2.7% copper and 10-55 g/t silver
§ Ro 23: 1.5m at 2.7% copper and 55 g/t silver
§ Ro 45: 2.4m at 1.4% copper and 18 g/t silver
§ Ro 25: 1.0m at 2.0% copper and 41 g/t silver
§ Ro 17: 1.3m at 1.2% copper and 24 g/t silver
§ Ro 15: 3.7m at 1.2% copper and 17 g/t silver
§ Ro 38: 1.8m at 0.7% copper and 15 g/t silver
o Mineralisation thicker than 1940 historical estimate: New intercepts demonstrate widths of 1.0-3.7m, significantly exceeding the maximum thickness used in the 1940 Historical Estimate (refer to announcement dated 20 October 2025)
o First Modern Assays for over 40 years: Results from re-sampling of 1980s drill core from holes located up to 12km apart show comparable or higher grades and thicker intercepts than original analysis, validating historical work and demonstrating resource upside and scale potential
o Confirms GreenX epigenetic model: Results confirm that mineralisation extends beyond the narrow Kupferschiefer shale horizon into the footwall and hanging wall, consistent with KGHM’s Polish operations (589,000tpa copper production) located on the same basement architecture
o Quality assured program: All samples meet strict QAQC standards, including >90% core recovery, with analysis by ISO/IEC 17025 accredited laboratory
o Significant program ahead: Initial assay results from six of 47 archived cores now reported, with the historical core re-sampling program continuing over the next quarter.

Figure 1: Map of reported assay results where greater than 90% of the historical core over the target interval was available from the archived core
· TANNENBERG COPPER PROJECT 2026 WORK PROGRAMME:
o In 2026, GreenX intends to progress an integrated programme to support JORC conversion, including completion of historical core logging/assaying and hyperspectral scanning, continued reprocessing/interpretation of historical geophysics and datasets, and advancing plans for twin drilling to verify historical estimates and underpin a Mineral Resource

§ 83kt of mineralised rock with a mean grade of 4.6% Sb at North Margeries
§ 58kt of mineralised rock grading at 3.2% W at South Margeries o
§ 32kt of mineralised rock grading at 1% W at North Margeries
o Potential to identify large scale deposits in new underexplored province with gold mineralisation associated with quartz veining at surface over a length of up to 15 km
o Field activities initially focusing on the shallow gold and high-grade tungsten and antimony potential are currently being finalised for 2026
o Cautionary statement: The Historical Estimates in this announcement are not reported in accordance with the JORC Code. A competent person has not done sufficient work to classify the Historical Estimate as a mineral resource or ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the Historical Estimate will be able to be reported as a mineral resource or ore reserve in accordance with the JORC Code

GreenX Metals #GRX – Targeting Gold, Tungsten & Antimony at Eleonore North Project in Greenland
24th November 2025 / Leave a comment
GreenX Metals Limited (ASX:GRX, LSE:GRX, GPW:GRX, Germany-FSE:A3C9JR) (GreenX or Company) is pleased to announce that following an extensive analysis of new and existing exploration data for the Eleonore North Project (ELN or Eleonore North) in Greenland since July 2024, GreenX now intends to issue the deferred consideration for the Eleonore North Project, being A$1 million in value of GreenX shares (escrowed for 12 months), and thereby GreenX retaining a 100% interest in the Project.
HIGHLIGHTS
- Outcropping gold and high-grade antimony mineralisation now confirmed at the Noa Prospect within the Eleonore North Project in East Greenland
- High-grade tungsten and antimony mineralisation also identified in Historical Estimate at the Margeries Prospects within the Eleonore North Project:
- 83kt of mineralised rock with a mean grade of 4.6% Sb at North Margeries
- 58kt of mineralised rock grading at 3.2% W at South Margeries
- 32kt of mineralised rock grading at 1% W at North Margeries
- Potential to identify large scale deposits in new underexplored province with gold mineralisation associated with quartz veining at surface over a length of up to 15 km
- Field activities initially focusing on the shallow gold and high-grade tungsten and antimony potential are currently being finalised for 2026
- GreenX will issue the deferred consideration (A$1 million in value of GreenX shares, escrowed for 12 months) in due course for the Eleonore North Project to retain a 100% interest in the Project
- Cautionary statement: The Historical Estimates in this announcement are not reported in accordance with the JORC Code (2012) (JORC Code). A competent person has not done sufficient work to classify the Historical Estimate as a mineral resource or ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the Historical Estimate will be able to be reported as a mineral resource or ore reserve in accordance with the JORC Code.
GreenX’s Chief Executive Officer, Mr Ben Stoikovich, commented: “We have been able to identify a number of potentially high value gold, tungsten and antimony targets at Eleonore North, which warrant further exploration. Tungsten and antimony are listed as critical minerals for the European Union and the U.S., and with gold at record prices, we are providing shareholders with exposure to a large and underexplored region for highly sought after minerals.
Over the coming months we will finalise the Eleonore North Project exploration programme for 2026, to further define and prioritise potential drill targets.”

Figure 1: Overview of gold and critical metal prospects within Eleonore North.
NOA PROSPECT- POTENTIALLY LARGE-SCALE BULK TONNAGE GOLD/ANTIMONY
The Noa Prospect is located within the ELN Project on exploration licence MEL 2023-39 and has the potential to host a “reduced intrusion-related gold system” (RIRGS), analogous to large bulk-tonnage deposit types found in Canada including Donlin Creek, Fort Knox and Dublin Gulch.
- Gold and antimony mineralisation documented at the high-priority Noa Prospect within Eleonore North2
- Geophysical “bullseye” anomaly 6 km wide co-incident with elevated gold and antimony mineralisation from historical geochemical sampling
- Anomalous gold mineralisation associated with quartz veining exposed at surface over a length of up to 15 km1
- Historical individual specimens grading up to 23% antimony (Sb), and other samples up to 4g/t gold (Au)1
- Previously reported historical data confirmed the presence of gold and high-grade antimony in outcropping veins at ELN including:
- 14 m long chip sample grading 7.2% Sb and 0.53g/t Au2
- 40 m chip line with a length weighed average of 0.78g/t Au2
- Antimony mineralisation has been identified along a ~4km trend in veins and structures, that broadly aligns with previously identified gold veining at surface within a 15 km trend1.
Eleonore North hosts antimony- and gold-bearing veins in an area sitting above a geophysical anomaly at Noa interpreted to be a pluton (Figure 2). A passive seismic survey in 2023 showed evidence for multiple blind intrusions rising to just beneath the surface3. Geological features such as the metal association and mineralisation style provide additional evidence for a RIRGS being active at the Noa prospect.

Figure 2: Historical results show evidence for high-grade antimony and gold mineralisation above the interpreted pluton at Noa.
Previous exploration was focused on orogenic gold mineralisation meaning that RIRGS targets have been overlooked. GreenX believes that the antimony-gold mineralisation above the pluton at Noa could be analogous to Perpetua Resources’ Stibnite Gold Project in Idaho, USA. There, RIRGS and orogenic gold mineralisation styles overprint each other.
During the 2023 field season, a passive seismic survey was undertaken above the pluton at Noa within ELN. Processing the results in 3D identified multiple blind plutons within the survey area. These 1 to 2 km-wide elongated plutons make ideal hosts for RIRGS mineralisation and are priority targets.
MARGERIES PROSPECTS – HIGH GRADE TUNGSTEN & ANTIMONY HISTORICAL ESTIMATE
The Margeries Prospects also are located within the ELN Project on exploration licence MEL 2018-19, where high-grade tungsten mineralisation and antimony mineralisation has been identified as follows, as historical estimates:
- 83kt of mineralised rock with a mean grade of 4.6% Sb at North Margeries
- 58.1kt of mineralised rock grading at 3.2% W at South Margeries
- 32kt of mineralised rock grading at 1% W at North Margeries
- Cautionary statement: The Historical Estimates in this announcement are not reported in accordance with the JORC Code. A competent person has not done sufficient work to classify the Historical Estimate as a mineral resource or ore reserve in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the Historical Estimate will be able to be reported as a mineral resource or ore reserve in accordance with the JORC Code.
- Over 2,000m of historical drilling completed with core still available in Greenland, as well as sighter metallurgical test work on the tungsten, both of which will be revisited and re-analysed by the Company’s geologists to aim to conform with JORC requirements
- Both tungsten and antimony are on the USA and EU critical raw materials list, both experiencing dramatic price increases over the last year due to Chinese restriction of exports with both commodities critical to defence and the energy transition
- The mineralisation is hosted within a >10 km strike length underexplored sulphide bearing hydrothermal vein system and east to west fault systems

Both the North and South Margeries targets host Historical Estimates including tungsten (W). North Margeries additionally includes an antimony (Sb) Historical Estimate. North and South Margeries are both within 10 km of fjords allowing ready shipping access. The region is mountainous with locally ice-covered plateaus and deep U-shaped valleys.
Previous Tungsten-Antimony Exploration
The first commercial exploration in the area was carried out by Nordisk Mineselskab A/S (Nordisk) who began their initial investigations in the western part of Ymer Island in the 1950s. Nordisk was dissolved in 1991 and the permit covering the North and South Margeries prospects was taken over by NunaOil A/S (NunaOil) in 1992. NunaOil later became (NunaMinerals). NunaMinerals held the licence until 2016 when the company went into liquidation.
Based on the historical data that the Company has now reviewed, exploration work by Nordisk began on Ymer Island in the 1950s after galena-bearing veins had been identified in the Noa area (Harpøth, 1986). Pan samples collected in streams of western Ymer Island in the 1970s led to the discovery of North Margeries and South Margeries.
These targets were drilled in 1981 and 1983 by Nordisk with a total of 35 holes for 2,240m. Shallower holes were drilled in 1981 using a diamond drill rig, while in 1983 deeper, percussion holes were drilled. In 1992, NunaOil took 137 stream samples. Between 2008 and 2014, NunaMinerals flew heliborne magnetics and electromagnetics surveys over Noa and Margeries valleys. The Company will revisit and re-analyse the historic drilling data with an aim to report it in accordance with the JORC Code.
Historic Metallurgical Test Work
Scoping level metallurgical test work by SGS Mineral Services UK in 2012 on a bulk sample from South Margeries has been obtained by the Company.
GreenX’s technical team will continue to review and verify the historical metallurgical test work, whilst assessing the opportunity to take samples from historic core for modern day mineralogical analysis and to obtain additional bulk samples for both tungsten and antimony metallurgical sighter test work, with an aim to be reported in accordance with the JORC Code.
Historical Estimate
In 1984, a Historical Estimate was prepared by Nordisk for North and South Margeries using the data collected during the drilling programs of 1981 and 1983.
At South Margeries, the mean value of the Historical Estimate is 58.1kt of mineralised rock grading at 3.2% W. At North Margeries, the Historical Estimate is 83kt of antimony-mineralised rock with a mean grade of 4.6% Sb and 32kt of tungsten-mineralised rock grading at 1% W.
The Historical Estimates were calculated by Nordisk using the original data collected by the same company.
No modern resource estimation compliant with current industry reporting codes such as JORC has been undertaken in the project area.
Cautionary statement: The Historical Estimates in this announcement are not reported in accordance with the JORC Code. A competent person has not done sufficient work to classify the Historical Estimate as a mineral resources or ore reserves in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the Historical Estimate will be able to be reported as a mineral resources or ore reserves in accordance with the JORC Code.

Critical Raw Materials
Both tungsten and antimony are on the USA and EU critical raw materials lists, with both recently experiencing dramatic supply constraints due to China announcing restriction of exports between late 2023 and February 2025, with both commodities being critical to defence, the energy transition and other industries.
ANTIMONY: Global strategic interest in antimony has significantly increased over the last 18 months due to several factors:
- China controls ~50% of global antimony mining, most downstream processing and 32% of global resources according to the Lowy Institute.
- China’s previously announced export ban on antimony has caused market disruption.
- Antimony is a crucial material in the defence supply chain, used in various military applications including ammunition, flame retardants, and smart weaponry.
- Antimony is essential in renewable energy technologies including more-energy-efficient solar panel glass containing and in preventing thermal runaway in batteries.
The antimony price has now climbed to US$60,000/t from historical prices of ~US$5,000 – 10,000/t. The strategic importance of antimony is such that during 2025 the US government has facilitated development of an investment in US antimony assets. In September 2025, the DLA awarded U.S. Antimony Corp an exclusive, sole-source contract for up to US$245 million to supply antimony metal ingots for the national defence stockpile.
In January 2025, the US government issued final permitting for Perpetua Resources’ Stibnite gold/ antimony project in Idaho. The Pentagon has committed nearly US$60 million to the project through the Defence Production Act. In October 2025 JPMorgan Chase (JP Morgan) announced that it will invest $75 million of its own funds for a ~3% stake in Perpetua from its recently announced $1.5 trillion investment fund for U.S. national security, a move underscoring the Perpetua’s key role in producing a metal which is used to make bullets and other weaponry.
TUNGSTEN: Global strategic interest in tungsten significantly increased in February 2025 when China announced sweeping export controls targeting tungsten and four other metals used across defence, clean energy and other industries. China’s export controls were announced minutes after an additional 10% tariff on Chinese goods imposed by U.S. President Donald Trump came into effect.
About 90% of global tungsten comes from Russia, China and North Korea, with China alone accounting for about 80 per cent of the world’s tungsten output. The US has not had domestic tungsten production since 2015.
Geology
The Project is centred around the >10 km thick, unmetamorphosed Late Precambrian Eleonore Bay Group (EBG) sedimentary package. Replacement type tungsten-antimony-gold mineralisation is hosted within wide sulphide-bearing hydrothermal veins and east to west fault systems (>10 km in length) which cuts sandstones, siltstones and shales of the Quartzitic Series of the EBG at Noa. The multicoloured series of the EBG (limestone, dolomite and dolomitic shale) hosts separate, high grade lenses of scheelite (tungsten) and stibnite (antimony) mineralisation at South Margeries and North Margeries, respectively.
The tungsten and antimony mineralisation in the Margeries Prospects occurs in silicified lensoid breccia zones in the central portions of graben like fault structures associated with E-W faults. The very high grades of tungsten and antimony and their restriction to discrete strata within the EBG is inferred to result from chemical traps offered by the availability of calcium within limestones and dolomites (scheelite mineralisation) and similarly the high concentrations of sulphur within the dolomite-shales (stibnite mineralisation). The vertical expression of the hydrothermally zoned mineralised system is upwards of 1,500 metres.
Exploration Potential
In 2008, NunaMinerals commissioned SkyTEM to conduct a helicopter-borne combined time domain electromagnetic (EM) and magnetic geophysical survey, comprising of 2,250 line kilometres. This resulted in the delineation of several significant geophysical targets within the area, many of which may correspond to known geochemical sediment anomalies. Hyperspectral surveying by NunaMinerals could potentially identify a unique spectral signature occurring with the structures hosting further mineralisation. This could be an important dataset for delineating the strike continuity of existing targets and the potential identification of additional mineralisation within the region (although no forecast is made of whether that may occur).
GreenX has acquired the historical hyperspectral data from the Danish and Greenlandic Geological Survey (GEUS) in Copenhagen and will appoint a geophysics contractor to process the data.
Drill core from the Historical Estimate at the Margeries Prospects exists in government archives and is available for inspection and sampling.
NEXT STEPS FOR THE ELEONORE NORTH PROJECT
Noa Prospect:
- Process the historical hyperspectral survey;
- Field mapping and sampling to ground-truth RIRGS targets and identify drill targets.
Margeries Prospects:
- Collect bulk sample material for both tungsten and antimony metallurgical sighter test work;
- Inspect the archive core with a view to obtaining samples for re-analysis and metallurgical sighter test work.
- Reprocessing of historic geophysics / hyperspectral data and field mapping to identify drill targets.
ELN COMMERCIAL TERMS
As announced on 15 July 2024 regarding the revised commercial terms for GreenX to acquire the Eleonore North Project, a final payment of A$1,000,000 in cash or GreenX shares was required for GreenX to retain the ELN Project after 31 December 2025.
GreenX now intends to retain its interest in ELN and accordingly will issue A$1,000,000 in value of GreenX shares (subject to 12 months escrow and based on the 5 trading day VWAP to 1 January 2026) in due course, but no later than 31 January 2026.
ARCTIC RIFT COPPER PROJECT (ARC) AND JOINT VENTURE
Given the prospectivity and focus on the Tannenberg Copper Project in Germany and at Eleonore North, and following a review of its portfolio of projects and the most efficient and effective use of the Company’s resources, GreenX has decided to withdraw from the ARC Joint Venture, which in accordance with the terms of the Earn-in and Joint Venture Agreement (JVA) between GreenX Metals Limited, its wholly owned subsidiary Mineral Investments Pty Ltd, and Greenfields Exploration Limited (GEX) dated 6 October 2021, will become effective in 90 days. As a result of the withdrawal from the JVA, the Company will recognise an impairment expense of A$7.77 million relating to the impairment of the exploration and evaluation asset previously recognised in relation to the ARC project.
