Berkeley Energia - Quarterly Report December 2025
RNS Number : 8571Q Berkeley Energia Limited 29 January 2026 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.

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). Figure 2: IP Conchas 4,492,225 North Cross Section 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.

| Sampling techniques | Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. | A trial Electrical Resistivity Tomography (ERT) survey was conducted at the Conchas Project in July 2025 by Análisis y Gestión del Subsuelo (AGS), under the supervision and coordination of Berkeley Minera España (BME), followed by a comprehensive campaign executed in October 2025. The measurements were taken using a Syscal Pro 72 geophysical unit manufactured by IRIS Instruments (Orleans, France). This fully digital resistivity and induced polarisation system is designed for environmental, civil engineering, and mineral exploration applications. It features an internal 250 W transmitter with a maximum output of 800-1000 V and 2.5 A, ten simultaneous acquisition channels providing up to 1,000 readings per minute, and automatic switching for up to 72 electrodes. The equipment ensures high-quality data acquisition and depth penetration suitable for subsurface investigations. The six multi-electrode cable reels used in the measurements were either manufactured by IRIS Instruments itself or by Beijing Harvest Technology Co, a Chinese company certified by IRIS Instruments as an approved supplier. This ensures compatibility and quality standards for the geophysical equipment used during surveys. |
| Include reference to measures taken to ensure sample representation and the appropriate calibration of any measurement tools or systems used. | The measurement procedure involved placing 36-108 electrodes along nine profiles, ranging from 350 to 1,070 metres in individual length (5,820m in total), with a 10m spacing between electrodes. All electrodes were connected to the measurement equipment, and a specific sequential program was used to select which quadrupoles operated at each time and in what configuration. The final output is a terrain section displaying resistivity values in different colours, representing variations in this parameter. The measurement profiles were referenced at various points with Global Positioning System ("GPS") to precisely determine their location and to obtain the terrain topography, which will allow for reprocessing of the data considering the surface relief. | |
| Aspects of the determination of mineralisation that are Material to the Public Report. | The lithium (Li) and rubidium (Rb) mineralisation is associated with a fine-grained, sub-horizontal muscovite leucogranite, overlaying a regional granite. Intercalations of the regional granite within the leucogranite are also present. In various zones of the orebody, limits are not well defined, and the selected geophysical method can assist in delineating these boundaries. | |
| In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. | The ERT system was deployed along nine profiles, ranging from 350 to 1,070 metres in individual length with varying orientations across the Conchas I permit. • A maximum electric load of 400 V was applied for both sequences. • Two measurement sequences were used: o The dipole-dipole sequence, optimised for detecting horizontal resistivity changes, with 2,921 data points. This method provides high lateral resolution and is sensitive to horizontal variations in resistivity, making it ideal for identifying geological boundaries and mineralised zones distributed horizontally. o The Schlumberger reciprocal sequence, used for detecting vertical resistivity changes, with 2,195 data points. This method is more sensitive to vertical variations and is commonly used for investigating stratified structures. • Both sequences utilised a pulse duration of 500ms and a measurement stack of 2-4, meaning each reading was averaged from 2 to 4 repeated measurements to ensure data reliability. • The measurements were taken using a Syscal Pro 72 geophysical unit manufactured by Iris Instruments. This fully digital resistivity and induced polarisation system is designed for environmental, civil engineering, and mineral exploration applications. It features an internal 250 W transmitter with a maximum output of 800-1000 V and 2.5 A, ten simultaneous acquisition channels providing up to 1,000 readings per minute, and automatic switching for up to 72 electrodes. GPS points were recorded with a Garmin eTrex 32x device at the start and end of each profile, as well as at the end of each cable segment along the profile. This ensures precise geolocation for the entire geophysical survey line using a robust, colour-display handheld GPS capable of tracking both GPS and GLONASS satellites. | |
| Drilling techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). | No drilling was completed. |
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed. | No drilling was completed. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. | The distribution of the electrodes and the sub-horizontaldisposition of the mineralisation result in the generated section being perpendicular to the contacts. | |
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. | No drilling was completed. | |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. | No drilling was completed. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. | The trial survey is considered qualitative in nature. No direct relationship is expected between resistivity values or ERT anomalies and mineralisation grade. | |
| The total length and percentage of the relevant intersections logged | No drilling was completed. | |
| Sub- sampling techniques and sample preparation | If core, whether cut or sawn and whether quarter, half or all core taken. | No drilling was completed. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. | No drilling was completed. | |
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. | The forward modelling and the detection of two types of rocks with different resistivity in the surveyed area demonstrate the suitability and effectiveness of the ERT method for the study. This approach validates the identification of lithological contrasts and supports further interpretation of subsurface geological structures. | |
| Quality control procedures adopted for all sub- sampling stages to maximise representation of samples. | AGS had an onsite representative during the survey assessing the data quality. The measurement equipment is inspected and calibrated by the manufacturer according to its technical specifications, ensuring measurement reliability, accuracy, and traceability for all data collected during the geophysical survey. After placing all measurement electrodes for each profile, the equipment checks each electrode for proper connection and acceptable resistivity reading. Once all electrode resistivity values fall within the instrument's tolerance limits, measurements can begin. For each profile, about 5,000 to 8,000 resistivity readings are collected, with each reading performed in stacks of 2-4 repetitions. If successive readings deviate beyond tolerance, the instrument repeats the measurement up to four times, averages the result, and-if within tolerance-moves to the next reading. This process ensures accurate, reliable data for geophysical analysis. | |
| Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. | The 10m distance between electrodes and the 350 to 1,070m length of the survey lines ensure a penetration depth of over 150m into the ground. | |
| Whether sample sizes are appropriate to the grain size of the material being sampled. | This spacing and length allow for effective subsurface electrical resistivity measurements to study geological features at significant depths. | |
| Quality of assay data and laboratory tests | The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. | No assaying is conducted. The ERT technique is appropriate for the purpose used. |
| For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. | An industry standard ERT survey was carried out by EGS along 350 to 1,070m lines. The main system parameters included: • A maximum electric load of 400 V was applied for both sequences. • Two measurement sequences were used: o The dipole-dipole sequence, optimised for detecting horizontal resistivity changes, with 2,921 data points. This method provides high lateral resolution and is sensitive to horizontal variations in resistivity, making it ideal for identifying geological boundaries and mineralised zones distributed horizontally. o The Schlumberger reciprocal sequence, used for detecting vertical resistivity changes, with 2,195 data points. This method is more sensitive to vertical variations and is commonly used for investigating stratified structures. • Both sequences utilised a pulse duration of 500ms and a measurement stack of 2-4, meaning each reading was averaged from 2 to 4 repeated measurements to ensure data reliability. • The measurements were taken using a Syscal Pro 72 geophysical unit manufactured by Iris Instruments.

GPS points were recorded with a Garmin eTrex 32x device at the start and end of each profile, as well as at the end of each cable segment along the profile. This ensures precise geolocation for the entire geophysical survey line using a robust, colour-display handheld GPS capable of tracking both GPS and GLONASS satellites. | |
| Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. | AGS has an onsite representative during the survey assessing the data quality. After placing all measurement electrodes for each profile, the equipment checks each electrode for proper connection and acceptable resistivity reading. Once all electrode resistivity values fall within the instrument's tolerance limits, measurements can begin. For each profile, about 5,000 to 8,000 resistivity readings are collected, with each reading performed in stacks of 2-4 repetitions. If successive readings deviate beyond tolerance, the instrument repeats the measurement up to four times, averages the result, and-if within tolerance-moves to the next reading. This process ensures accurate, reliable data for geophysical analysis. | |
| Verification of sampling and assaying | The verification of significant intersections by either independent or alternative company personnel. | The anomalies identified during the study carried out by AGS have been confirmed by their technicians. The detected anomalies appear to correspond well with the two main types of rocks present in the study area when compared with surface mapping and drillholes near the profiles. |
| The use of twinned holes. | No drilling was completed. | |
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. | The measurement sequences are generated in advance on a computer using ELECTRE Pro software and uploaded to the field instrument with PROSYS. The instrument stores all measurement data in its memory, which are then downloaded to a computer via USB with PROSYS. This software is used for initial data analysis and filtering, creating *.bin files. These files are exported as *.INV files to RES2dINV, which allows further analysis and filtering. The final interpreted profiles, with colour-coded resistivity variations, are saved as *.DAT files. | |
| Discuss any adjustment to assay data. | Data may be levelled and is treated as qualitative. | |
| Location of data points | Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. | GPS points were recorded with a Garmin eTrex 32x device at the start and end of each profile, as well as at the end of each cable segment along the profile. This ensures precise geolocation for the entire geophysical survey line using a robust, colour-display handheld GPS capable of tracking both GPS and GLONASS satellites. The Garmin eTrex 32x offers typical location accuracy within ±3.65m under good conditions. |
| Specification of the grid system used. | The project currently uses the UTM Datum ETRS89 Zone 29 North grid system. | |
| Quality and adequacy of topographic control. | Topographic control is based on a digital terrain model with sub metric accuracy sourced from the Spanish Geographical Institute (Instituto Geográfico Nacional). | |
| Data spacing and distribution | Data spacing for reporting of Exploration Results. | A total of 72 electrodes were spaced every 10m along each of nine 350 to 1,070m survey lines. |
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. | In ERT surveys, the spacing between electrodes critically affects the spatial resolution and depth of investigation. A 10m electrode spacing, as used in this study, provides a suitable balance to demonstrate continuity of lithology and resolve significant resistivity contrasts at depths beyond 150m. This spacing is adequate to detect and delineate subsurface features where mineralisation is oriented perpendicular to the survey lines, ensuring reliable geophysical imaging of the area. | |
| Whether sample compositing has been applied. | No composites reported. | |
| Orientation of data in relation to geological structure | Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. | Lithologies that are oriented perpendicular to the survey lines will be more prominent and apparent in the ERT results, making it easier to identify distinct resistivity contrasts and geological boundaries at the scale of interest during the geophysical survey. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. | No relevant bias is expected. | |
| Sample security | The measures taken to ensure sample security. | During the survey conducted by AGS, the data was kept under their custody. Berkeley received the interpreted data from AGS after the survey was completed. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. | Berkeley evaluated the data and determined that its quality is adequate for further analysis. The Company notes that there appears to be sufficient contrast between different lithologies and that the results correlate well with the existing data. |
