Quarterly Report December 2025

NEWS RELEASE | 29 January 2026

Quarterly Report December 2025

Highlights:

· Conchas Project

During the quarter, Berkeley Energia Limited (Berkeley or Company) continued to advance its ongoing exploration initiative targeting critical minerals in Spain at its Conchas project (Conchas or the project).

· Conchas hosts shallow, thick zones of lithium (Li) and rubidium (Rb) mineralisation, with accessory tin (Sn), caesium (Cs), beryllium (Be), niobium (Nb) and tantalum (Ta) within a muscovitic leucogranite unit

· SLR Consulting Ltd undertook metallurgical testing on representative samples from three diamond core holes during the quarter

· The preliminary metallurgical test work program, designed to assess the potential recovery of Li, Rb, and the other elements of economic interest, comprised head sample characterisation, mineralogical analysis, gravity, flotation and magnetic test work

· Flotation test work results demonstrated that very good recoveries of Li (78% overall recovery) and Rb (63% overall recovery) can be achieved at acceptable grades for -150µm grind size material

· Magnetic separation testing on -300µm +150µm material showed 77% of the Li and 58% of the Rb (stage recoveries) reporting to the magnetic product. This result may present an opportunity for magnetic separation processing of the coarser fraction followed by flotation of the finer material

· Next steps include 3D modelling of the drilling data to refine the geological interpretation of the Li and Rb mineralisation as a precursor to resource estimation, and a second phase of metallurgical test work to optimise the flotation and magnetic separation processes

· Rb is a critical raw material for advanced technology and industrial applications used in key sectors including defence and military, aerospace, communications, medical and renewable energy. The U.S. and Japan have both classified Rb as a Critical Mineral due to its strategic importance and growing demand in high-tech applications.

· International Arbitration against Spain

In May 2024, Berkeley advised that its wholly owned subsidiary, Berkeley Exploration Limited (BEL), had filed a Request for Arbitration (Request) for its investments in Spain through its Spanish subsidiary, Berkeley Minera España SA (BME), initiating arbitration proceedings against the Kingdom of Spain (Spain) before the International Centre for Settlement of Investment Disputes (ICSID).

BEL alleges that Spain's actions against BME and the Salamanca project (Salamanca Project) have violated multiple provisions of the Energy Charter Treaty (ECT), and that BEL is seeking preliminary compensation in the order of US$1 billion for these violations.

The timetable and arbitration rules have been established by the Tribunal, with the Company's Statement of Claim due to be filed in the coming weeks.

Notwithstanding the investment dispute, BEL remains committed to the Salamanca Project and continues to be open to a constructive dialogue with Spain. BEL is ready and open to collaborate with the relevant Spanish authorities to find an amicable resolution to the permitting situation and remains hopeful discussions can take place in the near term.

· Spanish Nuclear Power Industry:

· Almaraz Nuclear Power Plant Closure

o  Iberdrola, ENDESA and Naturgy, the owners of the Almaraz nuclear power plant in Extremadura, submitted a formal request in October 2025 to the Ministry for Ecological Transition and Demographic Challenge (MITECO) to extend the operational life of the Extremadura facility beyond 2027 to June 2030.

The formal request is the first necessary step for the continuity of the facility's operation beyond the planned closure dates to be studied.

o  Subsequent to the request, MITECO asked the Spanish Nuclear Safety Council (NSC) to issue a preceptive report regarding the modification of the operating license of the Almaraz nuclear power plant.

o  The Plenary Session of the NSC has agreed to issue a Supplementary Technical Instruction to the operator of the Almaraz nuclear power plant as part of the process related to the application for a modification of the plant's operating licence, which was submitted in November. The purpose of this instruction is to require the operator of Almaraz to submit additional documentation to carry out the necessary assessments and issue the corresponding mandatory report. The requested information must be submitted to the regulator as soon as possible and no later than February 2026.

· Nuclear debate continues in Spain

o  With Spain preparing to close its first nuclear power plant in 2027 (Almaraz), debate over the country's energy future after the 2025 blackout that plunged much of Spain and Portugal into darkness and exposed vulnerabilities in the Iberian grid has intensified.

o  Nuclear power plants generated ~20% of Spain's total net electricity production in 2024 and became its second largest source of electricity production, according to the country's nuclear industry forum ForoNuclear. The blackout that struck the Iberian Peninsula in 2025 highlights nuclear's role in providing inertia and stability to the electricity system, it said.

· Balance Sheet

The Company is in a strong financial position with A$68 million in cash reserves and no debt.

Critical Minerals Exploration Initiative

During the quarter, the Company continued to advance its exploration initiative targeting Li, Rb, Sn, Ta, Nb, tungsten (W), and other battery and critical metals, within its existing tenements in western Spain. Further analysis of the mineral and metal endowment across the entire mineral rich province and other prospective regions in Spain is also being undertaken, with a view to identifying additional targets and opportunities.

Conchas Project

The Investigation Permit (IP) Conchas is located in the very western part of the Salamanca province, close to the Portuguese border (Figure 1). The tenement covers an area of ~31km2 in the western part of the Ciudad Rodrigo Basin and is largely covered by Cenozoic aged sediments. Only the north-western part of the tenement is uncovered and dominated by the Guarda Batholith intrusion. The tenement hosts a number of sites where small-scale historical Sn and W mining was undertaken.

Figure 1: IP Conchas Location Plans and Geology / Drill Hole Location Plan

Berkeley conducted a small drill program comprising five broad spaced reverse circulation (RC) holes for a total of 282m in 2022 to test a Sn-Li soil sampling anomaly. Anomalous results for Li, Sn, Rb, Cs, Nb and Ta obtained from multi-element analysis of drill samples were reported in 2023, demonstrating Conchas' potential for several critical and strategic raw materials included in the European Commission's Critical Raw Materials Act (CRMA). The drill results included 25m @ 0.56% Li2O & 0.22% Rb2O from surface (CCR0002).

A follow-up RC and diamond core drilling program was completed in 2024. The drilling program comprised 33 RC holes for 1,857m drilled on a 100m by 100m grid, with depths ranging from 16m to a maximum of 169m. In addition, three diamond core holes for 230m were drilled to collect samples for metallurgical test work purposes.

All drill holes intersected muscovitic leucogranite hosted mineralisation with select intercepts including 61m @ 0.50% Li2O & 0.21% Rb2O from surface (CCR0012), 56m @ 0.48% Li2O & 0.21% Rb2O from surface (CCR0025), 27m @ 0.44% Li2O & 0.21% Rb2O from surface and 14m @ 0.95% Li2O & 0.39% Rb2O from 40m (CCR0006) and 18m @ 0.55% Li2O & 0.23% Rb2O from surface (CCR0017).

The multi-element mineralisation is largely associated with a sub-horizontal muscovitic leucogranite unit that locally outcrops at surface. The muscovitic leucogranite has a mapped extent of ~2km (in a NE-SW orientation) by ~1.2km (on average in a NW-SE orientation) (Figure 1) and varies in thickness from 7m to over 170m in the drill holes (Figure 2).

Preliminary Metallurgical Test Work Program Results

The Company engaged SLR to undertake metallurgical testing on representative samples obtained from three diamond core holes drilled in the 2024 program at the Conchas Project.

The preliminary metallurgical test work program was designed to assess the potential recovery of Li, Rb and the other elements of economic interest, and comprised:

· Head Sample Characterisation;

· Scanning Electron Microscope (SEM) Mineralogical Analysis;

· Gravity Test Work;

· Flotation Test Work; and

· Magnetic Test Work.

Head Sample Characterisation - Head Assay

A representative sub-sample was submitted to SLR's in-house analytical laboratory for head assay to determine the levels of target elements present in the composite sample. A sub-sample was also submitted to ALS Global for ICP multi-element analysis. The results of the SLR in-house assay and selected elements of the ALS analysis are given below in Table 1.

Table 1 - Summary of Head Assay Results

Head Sample Characterisation - Particle Size Distribution

A representative sub-sample of the -2mm feed material was subjected to particle size analysis by screen. The sample was wet screened at 53µm, the fractions dried and the +53µm fraction screened to generate mass data by fractions. The results, which determined a D80 particle size of 1,453µm, are summarised below in Figure 3.

Figure 3 - Graph of -2mm Feed Particle Size Distribution

Head Sample Characterisation - Class Size Analysis

A 2kg sample was ground to nominally generate a D80 size of 300µm and sized to generate five fractions for size-by-size analysis and sub-samples for mineralogical investigation. Representative sub-samples of the fractions were pulverised and submitted to SLR in-house laboratory for Li, Rb, Ta, Nb, Be, Sn, Iron (Fe) and Ce assay. Cs assays were subcontracted to ALS Global analytical services. The results are summarised below in Table 2.

Table 2 - Results of Class Size Analysis

The results generally show that elemental distributions followed the relative trends observed in the fraction mass distributions, with greater distributions present in the -300 +150µm fractions and the least in the -11µm fines fraction. Li distributions ranged from 33.4% in the -300 +150µm fraction to 5.0% in the -11µm fraction and Rb ranged from 34.2% to 5.2% in the respective fractions.

SEM Mineralogy Analysis

The target mineral phases identified include cassiterite, Nb-Ta oxides, polylithionite and muscovite. Muscovite was the most abundant target phase, maintaining relatively consistent concentrations across all size fractions (Figure 4).

The Li minerals were clustered in the polylithionite group which covers a range of minerals between zinnwaldite and lepidolite depending on the Fe and fluorine (F) contents. Cassiterite and Nb-Ta oxides were both present in trace quantities. The gangue material was primarily composed of plagioclase and quartz, present in nearly equal proportions. Plagioclase content increases in the finer size fractions, whereas quartz becomes less abundant. K-feldspar appears as a minor phase, while other phases, including phosphates, kaolinite, accessory minerals, tourmaline, sulphides, and topaz occur only in trace amounts.

Figure 4 - Mineral Phase Abundance

Gravity Test Work

The four fractions generated for the class size analysis were subjected to gravity release analysis (GRA) by treating each of the fractions separately on the Mozley super panner, generating six products for assay. The products were dried, weighed and representative sub-samples prepared and submitted for Li, Rb, Ta, Nb, Be, Sn and Fe assay.

Cumulative Li recoveries into the combined concentrates and middling product ranged from 28.0% at a grade of 0.16% Li (-53 +11µm) to 65.8% at a grade of 0.24% Li (0.52% Li2O) in the -150 +53µm fraction. Cumulative Rb recoveries into the combined concentrates and middling product ranged from 22.2% at a grade of 2,358ppm Rb (+300µm) to 66.1% at a grade of 2,049ppm Rb (2,242ppm Rb2O) in the -150 +53µm fraction.

The results showed optimum liberation size for the Conchas composite was in the -150 +53µm fraction.

Flotation Test Work

A short programme of flotation testing was performed on the Conchas composite to evaluate potential grades and recoveries at two grind sizes.

Two rougher tests were conducted at the 300µm (FT1-300) and 150µm (FT2-150) primary grind sizes to identify the better flotation performance, and one cleaner test was then conducted at the better performing grind size to evaluate the effect of kinetic cleaning on grades and recoveries.

The results of the rougher tests confirmed that the finer 150µm grind was the better performing test and was therefore used for cleaner flotation testing (FCT1-150). Cleaner flotation achieved 87.2% Li stage recovery, representing 77.5% overall recovery at a grade of 1.04% Li (2.23% Li2O), 70.9% Rb stage recovery representing 62.7% overall recovery at a grade of 0.79% Rb (0.87% Rb2O), and 78.5% Cs recovery at a grade of 661ppm Cs (Figure 5).

Flotation testing of the Conchas material demonstrated that very good recoveries of target minerals could be achieved at acceptable grades.

Figure 5 - Summary of Flotation Test Work Results for Li, Rb and Cs

Magnetic Test Work

Representative sub-samples of the 300µm and 150µm primary grinds were subjected to magnetic separation testing to evaluate potential grades and recoveries at the two grind sizes.

The 300µm sub-sample was screened at 150µm and the two fractions treated separately. The +150µm fraction was treated on an Eriez Log 1.4-disc separator, the -150µm treated on a Bunting Wet High Intensity Magnetic Separator (WHIMS) 500 jaw magnetic separator and the results combined to generate the overall performances. The 150µm sub-sample was treated on the Bunting WHIMS 500 jaw magnetic separator.

The initial magnetic test intensity was 4,000 Gauss with testing conducted in 1,000 Gauss increments up to 15,000 Gauss.

Magnetic separation testing on the <300µm +150µm material showed 76.6% of the Li and 57.7% of the Rb reporting to the magnetic product grading 2.34% Li2O and 0.73% Rb. This result may present an opportunity for magnetic separation processing of a coarser +150µm fraction followed by flotation of the finer -150µm material.

Magnetic separation on the <300µm +150µm material also showed 43.5% of the Ta and 50.9% of the Nb reported to the combined 4,000, 6,000 and 9,000 Gauss magnetic concentrates grading 1,161ppm Ta and 1,551ppm Nb.

Summary

Metallurgical testing of the Conchas mineralisation tested demonstrated very good recoveries at acceptable grades using flotation and magnetic separation methods.

The recommended next steps, from a metallurgical test work perspective, include more detailed flotation testing to optimise the rougher and cleaner flotation reagent schemes, optimisation of the magnetic separation on the coarse fractions, and mineral content variability testing to understand how variability affects the beneficiation methods.

Geological Modelling

3D modelling of the drilling data is being undertaken to refine the geological interpretation and assess volumes, average grades, and grade distributions for the Li and Rb mineralisation at different cut-offs, as a precursor to resource estimation.

An updated geological model based on all available data, including surface mapping, soil geochemistry and drilling, is also being developed.

Geophysical Survey - Electrical Resistivity Tomography (ERT)

ERT is a geophysical method used to determine the electrical resistivity distribution of the subsurface. By measuring resistivity variations, it is possible to generate a detailed resistivity profile of the underground environment. This technique is widely used in geotechnical engineering, environmental and geological investigations due to its effectiveness in mapping subsurface materials. The results of the ERT are not considered material.

A trial geophysical survey to determine the applicability of ERT to differentiate and map the key geological units at Conchas was undertaken during the prior quarter. The primary objective of the trial survey was to determine the effectiveness of ERT in mapping the host muscovitic leucogranite and underlying regional granite, and in turn provide an indication of the geometries, thicknesses, variations, intercalations etc. of the two granite units.

The trial survey was conducted by Spanish geophysical consultants, Análisis y Gestión del Subsuelo (AGS), and involved measurements along two profiles, each ~700m long, with electrodes spaced 10m apart, allowing data collection down to 150m depth.

The two ERT profiles obtained shows that the technique clearly distinguished, in the subsurface, two materials with a sufficient resistivity contrast to confirm the existence of two distinct lithological units. The ERT results were subsequently compared with proximal drill hole data, demonstrating good correlation with the mineralised muscovite leucogranite (LGM) and the underlying barren regional granite (GMG).

Following the promising results obtained from the ERT trail survey, a comprehensive survey was undertaken by AGS during the December quarter. The survey comprised nine profiles totalling 5,820 linear metres, ranging from 350m to 1,070m in length, with uniform 10m electrode spacing and maximum investigation depth reaching 153.5m (Figure 6). This systematic approach generated ~35,900 individual measurement points across the Conchas IP.

Figure 6 - Location of additional ERT Profiles

The new ERT data has consistently imaged the LGM unit at shallow depths across all profiles, with an irregular thickness distribution.

Review of the nine new ERT profiles has resulted in the interpreted scale and geometry of the host LGM unit being modified (Figure 7). ERT profiles located in the central part of the deposit (Profiles 2 & 7, Figures 8 & 10) appear to confirm the presence of the host LGM and underlying regional GMG, while profiles outside that central zone (Profile 4, Figure 9) extend and/or confirm possible LGM occurrences beyond the previously known limits (Figure 7).

The LGM attains a maximum thickness of ~100m within a prominent NNE-SSW band in the middle of the project area and pinches to 5-10m towards the tenement boundaries. Additionally, some profiles, particularly evident in the western half of Profile 7 (Figure 10), show multiple LGM units, suggestive of multiple magmatic pulses rather than a single phase.

Figure 8 - ERT Profile 2

Figure 9 - ERT Profile 4

Figure 10 - ERT Profile 7

Comparison of the ERT profiles with drillhole data confirms reliable geophysical-lithological correlation. The survey dataset has now been incorporated into 3D modelling (Figure 11), significantly refining the mineralised zone boundaries and contact geometry. This integrated geophysical framework substantially de-risks drill targeting within the LGM. In addition, the potential presence of additional LGM units at depth opens up new target zones that will be factored into the planning for follow-up drill campaigns.

Conchas Portugal

Given the interpreted continuity of the host muscovite leucogranite at Conchas into Portugal, the Company has submitted an application for the granting of prospecting and exploration rights for copper (Cu), lead (Pb), zinc (Zn), silver (Ag), gold (Au), antimony (Sb), Sn, W, Ta, Li, and other minerals, within an area referred to herein as "Conchas Portugal" to the Directorate General for Energy and Geology of the Ministry of Environment and Energy of Portugal.

The Conchas Portugal application, which covers an area of 219 km², is located in the District of Guarda and includes the municipalities of Sabugal and Almeida (Figure 12).

Figure 12: Conchas Portugal IP Application Location Plans

Oliva and La Majada Projects

These projects comprise three tenements within two project areas in Spain which are considered prospective for W, Sb, cobalt (Co) and other metals.

The Company has designed exploration programs for both projects, communicated with the relevant authorities, and conducted the required studies e.g. a birdlife study at the La Majada Project, to progress the pending grant of the IPs for two of the tenements.

An updated Exploration Program for the La Majada Project, together with the birdlife study and rehabilitation plan, was submitted to the relevant authorities during the year. The Exploration Program was updated to align it to new legislation recently introduced for the Castilla La Mancha Region.

The submitted documentation is currently being reviewed by the relevant authorities. Once the review is completed, the IP applications for two of the tenements (La Majada and Ampliación de los Bélicos) will be subjected to a public consultation period.

Salamanca Project Summary

The Salamanca Project is being developed in a historic uranium mining area in Western Spain about three hours west of Madrid.

The Company has received more than 120 European Union and National level approvals and favourable reports required for the initial development of the project to date.

The project has the potential to generate measurable social and environmental benefits in the form of jobs and skills training in a depressed rural community. It can also make a significant contribution to the security of supply of Europe's zero carbon energy needs.

The Project hosts a Mineral Resource of 89.3Mlb uranium, with more than two thirds in the Measured and Indicated categories. In 2016, Berkeley published the results of a robust Definitive Feasibility Study (DFS) for Salamanca confirming that the Project could be one of the world's lowest cost producers, capable of generating strong after-tax cash flows.

Salamanca Project Update

The Company continues with its commitment to health, safety and the environment as a priority.

An external audit of the Environmental and Sustainable Mining Management System was completed during the quarter to assess the System's compliance with the requirements of ISO Standards 14001:2015 "Environmental Management" and UNE 22480/70:2019 "Sustainable Mining Management". The audit, carried out by AENOR, concluded that the Environmental and Sustainable Mining Management System remains in full compliance with the relevant ISO Standards with no "Non-Compliance" items identified.

During the quarter, internal audit of the Health and Safety Management System was also carried out by recognised consultant QUIRON to assess the System's compliance with the requirements of ISO Standard 45001:2018 "Occupational Health and Safety Management Systems". The audit concluded that the Company's Occupational Health and Safety Management Systems remain in compliance with the relevant ISO Standards.

International Arbitration Dispute

In May 2024, the Company's wholly owned subsidiary, BEL, filed the Request for its investments in Spain through its Spanish subsidiary, BME, initiating arbitration proceedings against the Spain before ICSID.

As part of its Request, BEL alleges that Spain's actions against BME and the Salamanca Project have violated multiple provisions of the ECT, and that BEL is seeking preliminary compensation in the order of US$1 billion (US$1,000,000,000) for these violations.

In November 2022, BEL submitted a written notification of an investment dispute to the Prime Minister of Spain and the MITECO informing them of the nature of the dispute and the ECT breaches, and that it proposed to seek prompt negotiations for an amicable solution pursuant to article 26.1 of the ECT. The Spanish government has not engaged in any discussions related to the dispute to date, and BEL filed its Request in order to enforce its rights at the Salamanca Project through international arbitration.

The timetable and arbitration rules have been established by the Tribunal, with the Company's Statement of Claim due to be filed in the coming weeks.

Notwithstanding the investment dispute, BEL remains committed to the Salamanca Project and continues to be open to a constructive dialogue with Spain. BEL is ready and open to collaborate with the relevant Spanish authorities to find an amicable resolution to the permitting situation and remains hopeful discussions can take place in the near term.

Background to Dispute

In April 2021, the Spanish Government approved an amendment to the draft climate change and energy transition bill relating to the investigation and exploitation of radioactive minerals (e.g. uranium). The Government reviewed and approved the amendment to Article 10 under which: (i) new applications for exploration, investigation and direct exploitation concessions for radioactive materials, and their extensions, would not be accepted following the entry into force of this law; and (ii) existing concessions, and open proceedings and applications related to these, would continue as per normal based on the previous legislation. The new law was published in the Official Spanish State Gazette and came into effect in May 2021.

The Company's wholly owned subsidiary, BME, currently holds legal, valid and consolidated rights for the investigation and exploitation of its mining projects, including the 30-year mining licence (renewable for two further periods of 30 years) for the Salamanca Project, however any new proceedings opened by the Company are now not allowed under the aforementioned new law.

In November 2021, BME received formal notification from MITECO that it had rejected the construction of the plant as a radioactive facility (NSC II) at the Company's Salamanca Project following an unfavourable report for the grant of NSC II issued by the Board of the NSC in July 2021.

BEL strongly refutes the NSC's assessment and, in its opinion, the NSC adopted an arbitrary decision with the technical issues used as justification to issue the unfavourable report lacking in both technical and legal support.

BME submitted documentation, including an 'Improvement Report' to supplement its initial NSC II application, along with the corresponding arguments that address all the issues raised by the NSC, and a request for its reassessment by the NSC, to MITECO in July 2021.

Further documentation was submitted to MITECO in August 2021, in which BME, with strongly supported arguments, dismantled all of the technical issues used by the NSC as justification to issue the unfavourable report. BME again restated that the project is compliant with all requirements for NSC II to be awarded and requested its NSC II Application be reassessed by the NSC.

In addition, BME requested from MITECO access to the files associated with the Authorisation for Construction and Authorisation for Dismantling and Closure for the radioactive facilities at La Haba (Badajoz) and Saelices El Chico (Salamanca), which are owned by ENUSA Industrias Avandas S.A., in order to verify and contrast the conditions approved by the competent administrative and regulatory bodies for other similar uranium projects in Spain.

Based on a detailed comparison of the different licensing files undertaken by BME following receipt of these files, it is clear that BME, in its NSC II submission, has been required to provide information that does not correspond to: (i) the regulatory framework, (ii) the scope of the current procedural stage (i.e., at the NSC II stage), and/or (iii) the criteria applied in other licensing processes for similar radioactive facilities). Accordingly, BEL considers that the NSC has acted in a discriminatory and arbitrary manner when assessing the NSC II application for the Salamanca Project.

In BEL's strong opinion, MITECO has rejected BME's NSC II Application without following the legally established procedure, as the Improvement Report has not been taken into account and sent to the NSC for its assessment, as requested on multiple occasions by BME.

In this regard, BEL believes that MITECO have infringed regulations on administrative procedures in Spain but also under protection afforded to BEL under the ECT, which would imply that the decision on the rejection of BME's NSC II Application is not legal.

In April 2023, BME submitted a contentious-administrative appeal before the Spanish National Court in an attempt to overturn the MITECO decision denying NSC II.

Further, the BME received formal notifications in December 2023 which upheld appeals submitted by a non-governmental organisation, Plataforma Stop Uranio, and the city council of Villavieja de Yeltes (the appellants) to revoke the first instance judgements related to the Authorisation of Exceptional Land Use (AEUL) and the Urbanism License (UL), which annuled both the AEUL and UL.

The AEUL and the UL were granted to BME in July 2017 and August 2020 by the Regional Commission of Environment and Urbanism, and the Municipality of Retortillo respectively.

The appellants subsequently filed administrative appeals against the AEUL and the UL at the first instance courts in Salamanca. The administrative appeals against the AEUL and UL were dismissed in September 2022 and January 2023 respectively.

One of the appellants subsequently lodged appeals before the High Court of Justice of Castilla y León (TSJ), with the TSJ delivering judgements in December 2023 to revoke the first instance judgements and declare the AEUL and the UL null.

BME strongly disagrees with the fundamentals of the TSJ's judgement and having previously submitted cassation appeals against the TSJ judgements before the Spanish Supreme Court, BME has withdrawn the appeals to preserve BEL's rights under international arbitration.
