NEWS RELEASE | 30 April 2025

 

Quarterly Report March 2025

 

Summary:

 ·    Exploration at Conchas Project
 During the quarter, Berkeley Energia Limited (Berkeley or Company) announced
 the results of a reverse circulation (RC) and diamond drilling program
 completed at the Conchas project (Conchas Project), as part of its ongoing
 exploration initiative targeting critical minerals in Spain.
 Highlights included:
 ·      Assay results demonstrated shallow, thick zones of lithium and
 rubidium mineralisation, hosted within a muscovitic leucogranite, intersected
 in all 33 RC holes.
 ·      Drill intercepts include:
 o  14m @ 0.95% Li(2)O & 0.39% Rb(2)O (from 40m)
 o  18m @ 0.55% Li(2)O & 0.23% Rb(2)O (from surface)
 o  61m @ 0.50% Li(2)O & 0.21% Rb(2)O (from surface)
 o  27m @ 0.44% Li(2)O & 0.21% Rb(2)O (from surface)
 o  56m @ 0.48% Li(2)O & 0.21% Rb(2)O (from surface)
 ·      Samples from an additional three diamond holes completed in the
 drill program have been sent for preliminary metallurgical test work with
 results anticipated in the June 2025 quarter.
 ·      Next steps include 3D modelling of the drilling data and
 completion of the preliminary metallurgical test work program.
 ·     Rubidium 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 rubidium 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).
 As part of its Request, 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 (US$1,000,000,000) for these violations.
 During the quarter, the Tribunal was formally constituted with the first
 tribunal session to be held in early May 2025, where the timetable and
 arbitration rules will be established.
 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:
 During and subsequent to the end of the quarter, there have been a number of
 important recent developments regarding the nuclear industry in Spain,
 including:
 ·      Proposal to Reverse Spain's Nuclear Phase-out Approved by
 Parliament
 o  A Plenary Session of the Spanish Congress has approved a non-law proposal
 calling for the government to implement a series of measures that would
 reverse the country's decision to phase out nuclear power. Under current
 plans, Spain's power reactors are all scheduled to shut between 2027 and 2035.
 The proposal, presented by the right-wing People's Party (PP), was passed in
 February 2025. This non-law proposal is not binding but urges the Spanish
 Government to consider its content.
 o  Subsequently, in early April, the PP registered a bill in the Congress to
 extend the useful life of Spanish nuclear power plants. The bill has been
 registered by the Spanish Congress and sent to the Government for their
 comments and response due late May 2025.
 ·      Demonstrations
 o  Approximately 7,000 people attended a demonstration against the planned
 closure of the Almaraz nuclear power plant in Extremadura as part of the
 country's nuclear phase out policy.

 The demonstration was called by the municipalities in the area of influence of
 the Almaraz nuclear power plant and the citizens' platform "Yes to Almaraz,
 Yes to the Future" to demand the continuation of the activity of the
 Extremadura plant in light of the closure planned by the central government.
 ·      Nuclear Power Plant Continuation
 o  One of Spain's nuclear operators, said it has received notification of the
 ministerial order extending the operating permit for the Trillo nuclear power
 plant until November 2034. The Ministry for Ecological Transition and the
 Demographic Challenge (MITECO) had considered the favourable report issued on
 by the Nuclear Safety Council (NSC) in its decision to grant the operating
 extension.
 ·      Nuclear Industry Manifesto
 o  Companies representing the Spanish nuclear industry have signed a
 manifesto calling for the long-term operation of the country's nuclear power
 plants. Under current plans, Spain's power reactors are all scheduled to shut
 by 2035.
 The manifesto - signed by 32 companies, including Empresarios Agrupados-GHESA
 (EAG), Framatome, GDES, GE Vernova, IDOM and Westinghouse - says: "We urge the
 initiation of a dialogue and renegotiation of the 2019 agreement on the phased
 shutdown of nuclear power plants. This agreement was made under an industrial,
 geopolitical, social and economic context that is vastly different from
 today's reality."
 The signatories call on the Spanish government and relevant authorities to
 revise the National Integrated Energy and Climate Plan to incorporate measures
 ensuring the continuity of nuclear energy. "This energy source must be
 recognised as reliable, efficient and competitive, with low carbon emissions,
 and should receive fair treatment to encourage investment," they say.
 ·     Balance Sheet
 The Company is in a strong financial position with A$78 million in cash
 reserves and no debt.

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

During the quarter, the Company continued with its commitment to health,
safety and the environment as a priority.

Berkeley has been awarded with the Carbon Neutrality Certificates for the
years 2020, 2021, and 2022, by MITECO. This represents an important step in
the Company's journey to combat climate change and continue contributing to
sustainability.

To achieve this goal, 329 trees have been planted within the reforestation
project in the public utility forest area of the Monte del Catálogo de
Utilidad Pública in the province of Ávila, No. 13 "El Pinar," located in the
municipality of Mijares.

These trees will absorb a total of 56 tons of CO(2), a quantity expected over
a 40-year period according to the reference values from the MITECO Registry.
The species planted include Scots pine, birch, rowan, yew, and holly.

Thus, Berkeley, in its commitment to fighting climate change, contributes to
the following Sustainable Development Goals:

Exploration

During the quarter, the Company continued with its exploration program
focusing on critical minerals in Spain. The exploration initiative is
targeting lithium, rubidium, tin, tantalum, niobium, tungsten, and other
battery and critical metals, within the Company's existing tenements in
western Spain that do not form part of Berkeley's main undertaking being the
development of the Salamanca Project.

Conchas Project

The Investigation Permit (IP) Conchas is located in the very western part of
the Salamanca province, close to the Portuguese border (Figure 2).  The
tenement covers an area of ~31km(2) 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 tin and tungsten mining was undertaken. In addition, several
mineral occurrences (tin, tungsten, titanium, lithium) have been identified
during historical mapping and stream sediment sampling programs.

Figure 2: IP Conchas Location Plans and Geology / Drill Hole Location Plan

Billiton PLC undertook exploration on the IP Conchas between 1981 and 1983,
with a focus on tin and tantalum (lithium, rubidium and other elements were
not taken into account). Billiton's work programs comprised regional and
detailed geological mapping, geochemistry, trenching and limited drilling.

Soil sampling programs completed by Berkeley in the northern and central
portions of the tenement during 2021 (200m by 200m) and 2022 (100m by 100m)
defined a tin-lithium anomaly covering approximately 1.1km by 0.7km which
correlated with a mapped aplo-pegmatitic leucogranite.

Based on the results of the soil sampling programs and information gleaned
from a review of the available historical data, a small initial drilling
program was implemented in 2022 to test the tin-lithium anomaly.

The drill program comprised five broad spaced RC holes for a total of 282m.
Anomalous results for lithium (Li), tin (Sn), rubidium (Rb), cesium (Cs),
niobium (Nb) and tantalum (Ta) obtained from multi-element analysis of drill
samples were reported in April 2023, demonstrating Conchas' exploration
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% Li(2)O and 0.22% Rb(2)O from surface (CCR0002).

The occurrence of these six elements is observed to be largely associated with
a sub-horizontal muscovitic leucogranite unit that locally outcrops at
surface. The muscovitic leucogranite has a mapped extent of approximately 2km
(in a NE-SW orientation) by 1.2km (on average in a NW-SE orientation) (Figure
2) and varies in thickness from 7m to over 170m in the drill holes (Figure 3).

A number of mineralogical studies have been undertaken to determine the
mineral species present and understand their characteristics and properties.
Results of these studies indicate the mineralised muscovitic leucogranite is
composed mainly of plagioclase (average content of 55%) and quartz (average
content of 25%), with potassium feldspar, muscovite mica, and Li-mica making
up remainder of the rock. The samples have an average Li-mica content of 3%.

2024 Drilling Program

A follow-up RC and diamond core drilling program focused on improving
confidence in the geology, continuity, and grade distribution of the zone of
multi-element mineralisation was completed in late 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,
confirming and improving upon the results obtained in the 2022 drilling
campaign. Select intercepts include:

 Hole No.  Down Hole Intercept                  From Depth

                                                (Down Hole)
 CCR006    27m @ 0.44% Li2O & 0.21% Rb2O        surface

           14m @ 0.95% Li2O & 0.39% Rb2O        40m
 CCR011    55m @ 0.31% Li2O & 0.18% Rb2O        surface
 CCR012     61m @ 0.50% Li2O & 0.21% Rb2O       surface
 CCR017    18m @ 0.55% Li2O & 0.23% Rb2O        surface
 CCR025    56m @ 0.48% Li2O & 0.21% Rb2O        surface
 CCR033    19m @ 0.35% Li2O & 0.21% Rb2O        surface

 

Based on geological logging of all drill holes and the assay results returned
from the RC holes, the following observations were made regarding geology,
continuity, and grade distribution:

 ·      the mineralised muscovite leucogranite is very homogeneous in
 terms of mineralogy
 ·      the distribution of Rb mineralisation is the most consistent
 among all anomalous elements within the zone of mineralisation
 ·      there is a strong positive correlation between Li and Rb grades,
 which may be associated with the varying presence of micas
 ·      there is a positive correlation between Nb and Ta grades, which
 appears to be associated with the presence of columbo-tantalite and/or
 cassiterite
 ·      the southern zone of mineralisation contains the highest grades
 overall, with individual assay values exceeding 2.5% Li(2)O. In this area, all
 holes penetrated the host muscovitic leucogranite and ended in the underlying
 regional granite (Figure 3)
 ·      In the northeast, the muscovite leucogranite is significantly
 thicker (>169m in CCR020) and all holes returned Rb(2)O grades exceeding
 1,000ppm (Figure 4) however, Li(2)O grades are lower than in the south and
 northwest areas
 ·      None of the northeastern most holes reached the underlying
 regional granite, suggesting a potential feeder zone
 ·      Drilling in the northwest recorded the highest grades of both
 Li(2)O and Rb(2)O, as well as the highest grades of other elements

 

Surface geological mapping was also conducted as part of the recent
exploration activities. Based on field observations, the surface area occupied
by the muscovitic leucogranite is greater than indicated by historical
mapping, which when combined with the drilling results, expands the scale of
the host unit.

Next Steps

Representative samples obtained from the three diamond core holes drilled in
the 2024 program have been sent to the Oviedo School of Mines' (Spain) and
Wardell Armstrong International's (England) laboratories for preliminary
metallurgical test work.

The metallurgical test work programs have been designed to assess the
potential recovery of Li, Rb and the other elements of economic interest, and
comprise crushing and grinding (bond index calculation), gravity (jigs,
shaking tables and multi gravity separator), high intensity wet and dry
magnetic separation on the concentrates, froth flotation, and characterisation
of the samples.

Various workstreams have advanced during the quarter, with results of the
metallurgical test work programs anticipated in the June 2025 quarter.

3D modelling of the drilling data is also 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.

Rubidium(1,2,3,4,5)

Rubidium is a critical raw material with growing significance in advanced
technology and industrial applications, including in the defence and military,
aerospace, communications, biomedical and renewable energy sectors.

Its unique properties make it indispensable for producing special crystals
used in night-vision equipment and fibre-optic telecommunications systems.
Other applications include precision timekeeping in atomic clocks, which are
vital for global positioning systems (GPS), telecommunications, and space
exploration.

Rubidium compounds play a key role in the production of specialty glasses,
cutting-edge electronics, radiation detection devices and medical imaging
technologies, ensuring their relevance across multiple high-growth sectors.

Specialty glasses, currently the largest market for rubidium, are utilised in
night vision equipment and fibre-optic telecommunications systems. Rubidium
carbonate is used as an additive to these types of glass, lowering electrical
conductivity and improving stability and durability.

Rubidium's photo-emissive properties lead to its application in motion-sensor
devices, night-vision devices, photoelectric cells, and photomultiplier tubes.
These applications highlight its importance in advanced electronic devices,
particularly in sectors requiring precision and reliability.

Its application in photocells, which convert light into electric currents, is
significant. These photocells are primarily used as sensors to regulate
lighting in buildings, showcasing rubidium's role in energy-efficient
technologies.

Rubidium-based atomic clocks are used in military communication systems,
navigation equipment, and precision-guided weapons. The increasing focus on
defence modernisation and the need for secure and reliable communication
systems are expected to drive the demand for rubidium in the military
sector.

Rubidium is also increasingly used as a key component in advanced batteries,
particularly in the development of high-energy-density batteries for electric
vehicles and renewable energy applications.

Global production of rubidium is limited, with no rubidium production recorded
globally outside of China in 2023.

Due to its strategic importance and growing demand in high-tech applications
used in key industry sectors, the United States of America and Japan have both
classified rubidium as a Critical Mineral, essential to their economic or
national security, and with a supply chain vulnerable to disruption.

Oliva and La Majada Projects

These projects comprise three tenements within two project areas in Spain
which are considered prospective for tungsten, cobalt, antimony, 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, have been submitted to the relevant
authorities during the quarter. The Exploration Program was updated to align
it to new legislation recently introduced for the Castilla La Mancha Region.

International Arbitration Dispute

In May 2024, the Company's wholly owned subsidiary, Berkeley Exploration
Limited (BEL), 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
International Centre for Settlement of Investment Disputes (ICSID).

As part of its Request, BEL alleges that Spain's actions against BME and the
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 (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 Request was submitted by BEL's arbitration lawyers based in Spain.
Subsequent to the quarter, BEL agreed an engagement letter with its lawyers to
provide ongoing arbitration services on a reduced and capped fee basis that
also includes a three percent success fee which is capped and is only payable
to the lawyers in the event of a successful award and if monetary damages are
received by BEL.

Previously, BEL received the Notice of Registration from ICSID with the
Registration of the Arbitration published on the ICSID website. During the
quarter, the Tribunal was formally constituted with the first tribunal session
to be held in early May 2025, where the timetable and arbitration rules will
be established.

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.
