OPERATIONAL ACTIVITIES
CARAÍBAS AND SIDRÔNIO PROJECT OVERVIEW (100% L1M)
The Group completed its acquisition of the option to acquire the Caraíbas and Sidrônio lithium projects in
the prolific Lithium Valley region of Minas Gerais, Brazil. Managing Director, Alex Biggs spent June in Brazil
visiting the project areas and the Lithium Valley region meeting with key stakeholders and developing a
team to complete on ground works. Subsequent to end of Financial Year work programs have begun
consisting of ground reconnaissance, geophysics and soil sampling in order to identify drill targets to be
drilled towards the end of the calendar year.
DUNDAS PROJECT OVERVIEW (100% L1M)
The Dundas project has been a key area of focus over the past 12-months with soil sampling and drilling
continuing to define lithium anomalism and areas of interest for further follow up. Multiple pegmatites have
been discovered under alluvial cover on tenement E63/2001 (ASX Announcement 13 July 2023 and ASX
Announcement 29 September 2023) with further areas of interest identified on tenement E63/2000
through auger drilling (ASX Announcement 13 May 2024). RC drilling on E63/2000 was as a result of strong
lithium anomalism up to 218ppm Li (ASX Announcement 13 July 2023) with results up to 994ppm Li (ASX
Announcement 13 May 2024). These results are considered positive and greater than background grades
for lithium and provide an opportunity to now vector in on a potential source of lithium mineralisation.
DALMAS AND HIVER PROJECT OVERVIEW (100% L1M)
The Dalmas and Hiver projects were acquired in September 2023 (ASX Announcement 29 September
2023). A first pass reconnaissance program was completed across both projects identifying multiple
pegmatite lithologies (ASX Announcement 03 November 2023) which are broadly coincident with 113
targets at Dalmas and 52 targets at Hiver that were identified through multispectral analysis (ASX
Announcement 30 August 2023).
MAILMAN HILL PROJECT OVERVIEW (100% L1M)
An inaugural auger sampling campaign was completed in June 2024 (ASX Announcement 11 June 2024)
to test 9km of highly prospective lithology within the Keith-Kilkenny Tectonic Zone immediately southeast
of Cavalier Resources’ (ASX:CVR) Crawford Gold Project which is located directly to the north-west of the
Mailman Hill tenement. The project hosts a JORC compliant Resource of 3.75Mt @ 1.0g/t Au for 118koz
(1.15Mt @ 1.0g/t Au Indicated, 2.60Mt @1.0g/t Inferred). The Project has a maiden ore Reserve of 1.00Mt
@0.9g/t Au for 29koz and is progressing to the permitting stage (see ASX announcement 14 March 2024,
Cavalier Resources (ASX: CVR)). The Group is investigating the potential of an extension to the Crawford
Gold Project south-east onto its Mailman Hill tenement and will be receiving assays in Q3 CY2024.
MT JEWELL PROJECT OVERVIEW (100% L1M)
The Group has continued to evaluate the potential of the Mt Jewell project during the year.
MT BARTLE PROJECT OVERVIEW (100% L1M)
The Group has continued to evaluate the potential of the Mt Bartle project during the year. The tenements
are still pending grant.

ACQUISITION OF CARAÍBAS AND SIDRÔNIO LITHIUM PROJECTS IN BRAZIL
The Group completed the acquisition of Bengal Mining Pty Ltd in June 2024 which holds, via its wholly
owned subsidiary Tigre Mineracao Ltda (Tigre) option agreements over two lithium projects, Caraíbas and
Sidrônio in Brazil’s prolific Lithium Valley district in the state of Minas Gerais.
THE EASTERN BRAZILIAN PEGMATITE PROVINCE - LITHIUM VALLEY
The Esperança project is located in the Lithium Valley region of Minas Gerais, Brazil. The region hosts Latin
Resources’ (ASX: LRS) Colina lithium project hosting 70.9Mt @ 1.25% Li20 (Measured + Indicated 67.3Mt @
1.27% Li20, Inferred 3.6Mt @ 1.10% Li20). Also in the region is Signa Lithium’s (NASDAQ: SGML) Grota do
Cirilo project hosting 108.9Mt @ 1.41% Li20 (Measured and Indicated 94.3Mt @ 1.40% Li20, Inferred14.6Mt
@ 1.37% Li20). The region has emerged as one of the world’s premier lithium districts over the past few
years and presents significant exploration potential.
The Group will benefit from access to a seasoned ground team, providing invaluable fieldwork expertise
and insights, enhancing the Group's strategic approach to exploration. Relationships the Group already
has in the region will help facilitate project growth and advancement. Due to location the Project will benefit
from current works being carried out at the Group’s Caraíbas and Sidrônio lithium projects which began in
July 2024 (ASX Announcement 24 July 2024).
Minas Gerais is Brazil’s third largest economy with over 300 mines operating in the state with tier-1
operators including Vale, BHP and Rio Tinto. The state boasts a strong mining labour pool and presents a
cost competitive jurisdiction for exploration and project development with mature infrastructure, hydro
power and road access.
CARAÍBAS AND SIDRÔNIO PROJECTS
The Projects are located in the Eastern Brazilian Pegmatite Province that encompasses approximately
150,000 km2, stretching from Bahia state to Rio de Janeiro state. The Caraíbas Project consists of five (5)
separate tenements covering 1,733 Ha and the project area contains a series of albite and muscovite rich
pegmatites identified by Bengal’s initial reconnaissance works. Aeromagnetic data shows the tenements
are located along regional structures and shear zones which are analogous to the trends present at Latin
Resources’ (ASX: LRS) Colina deposit. The Caraíbas Project is located approximately 20km to the south in
the same Salinas geological formation.
The Sidrônio Project consists of two (2) tenements covering 1,638 Ha, strategically located adjacent and
along strike to the south from the Caraíbas Project. Aeromagnetic data shows the tenements are located
along similar interpreted structural trends that may potentially be conduits for mineralisation.
5
Figure 1: Caraíbas and Sidrônio project location, geology and tenements
Both Projects cover prospective Salinas Formation geology which is thought to provide adequate
rheological conditions suitable for the emplacement of late hydrothermal fluids. In similar geological
settings, proximal to S-type granites, the Salinas Formation is known to host fertile lithium mineral bearing
pegmatites.
Records from the ‘Project Evaluation of the Potential of Lithium in Brazil’ - Servico Geologico do Brasil
(Geological Service of Brazil) indicate that historic prospecting or fossicking may have occurred with the
Caraíbas Project. At this location an inactive mine location is recorded as ‘LB-43 Lavra Luís Rocha – Caraíbas’
which is interpreted to be a small-scale prospecting excavation. The area was then targeted by Bengal
company geologists in late 2023 as part of a small reconnaissance program to identify lithium prospectivity
in the region. Three rock chip samples were taken from the site with peak assay results of 0.53% Li2O, 1,245
6
ppm tantalum, 1,175 ppm rubidium and 1,455 ppm caesium (Table 1). Geological descriptions of the rock
samples are shown in Table 2, and photographs of BLR237 and VLR1269 are shown in Figure 2 (a) and
Figure 2 (b) respectively. These results are considered encouraging and support the thesis that pegmatites
in the project areas might have favourable geochemistry and fractionation conditions. Elevated tantalum
levels are considered a good indicator of potential for adequate fractionation conditions and will form a
key part of the Group’s initial reconnaissance works and analysis. These results formed the basis of the
initial works program across the project areas which has begun subsequent to end of year and date of this
report. A full table of results for samples taken from the project areas are included in Appendix 2, Table 1
in ASX Announcement 22 April 2024.

REGIONAL GEOLOGY, PROSPECTIVITY AND TRENDS
The Eastern Brazilian Pegmatite Province is a globally recognised region for hard rock lithium prospectivity.
The Colina and Grota do Cirilo Project Lithium resources highlight the potential for the region to host Tier
1 lithium deposits. Like Caraíbas and Sidrônio, these deposits are located within the Salinas Formation
proximal to Post-Collisional Magmatism which are of the Type-S granitic geochemistry. S-Type granites
are known to be favourable and form part of the genetic model for the creation of lithium-caesium-tantalum
(LCT) deposits. The Salinas Formation commonly includes lithologies such as mica-quartz schists and
quartz-mica schists with localised intercalations of rocks, calcium-silicates, meta conglomerates and
micaceous quartzites. Reconnaissance work by Bengal has identified similar rock types at both the Caraibas
and Sidronio projects which are considered positive indicators when looking at the projects in a regional
context.

8
Multiple prospective geophysical trends have been identified through interpretation of publicly available
aeromagnetic data from the Servico Geologico do Brasil (Geological Service of Brazil) which correlates with
the parallel mineralised corridor that hosts Latin Resources’ (ASX: LRS) Colina deposit. These trends will
form the basis of further on-ground mapping, reconnaissance, and sampling across the tenements with a
view to defining drill targets.
PROGRAM OF WORKS AND USE OF FUNDS
The option agreements that the Group has acquired via Bengal allows for clear identification of drill targets
prior to full acquisition of the Project areas, either in full or in part. The Group has existing relationships with
contractors and personnel in the region which will significantly accelerate its work programs and has a
strong relationship with other operators in the region.
The following work programs will be completed across all projects. These work plans have begun
subsequent to end of year and the date of this report.

RECONNAISSANCE SITE VISIT CONFIRMS LITHIUM POTENTIAL
The Group completed a site trip to the Caraíbas and Sidrônio project areas in June 2024. Positive
indications from the site visit include the verification of previously identified outcropping pegmatites
containing lithium bearing minerals (Lepidolite) within artisanal workings at the Caraíbas project.
Numerous pegmatite showings were also observed across both the Caraíbas and Sidrônio project areas
indicating the presence of pervasive hydrothermal activity.

the artisanal workings (C) Example of the excavated feldspar-mica-tourmaline-lepidolite pegmatite boulders surrounding
the site. (D) Example of typical pegmatite outcrops within stream beds throughout the project areas
Pegmatite boulders at the location (Figure 4 (C) are scattered due to artisanal mining activities and are
generally of a feldspar-mica-tourmaline-lepidolite mineral assemblage. The presence of lepidolite,
tourmaline, accessory rubelite and tantalite are compelling indicators that the source geochemistry may
be approaching the correct composition.
The pegmatite outcrop continues along strike from the artisanal workings but is covered by thin 2-4m
residual saprolites from weathered Salinas Formation schists. Pegmatite mapping will be a priority for
forward works.
11
Various sites were then visited across the greater Caraíbas and Sidrônio projects. As a first pass exploration
strategy local geologists traverse stream beds which both provides access and strips saprolite from the
bedrock to expose the geology beneath. Numerous pegmatite occurrences have been identified using
this technique along ephemeral drainage systems (Figure 4 (D) which is especially encouraging given the
lack of overall exploration data for the region. A comprehensive outcrop geology mapping exercise to
properly locate, geochemically sample, and structurally map the pegmatites utilising the stream exposures
is now being considered in conjunction with a stream sediment sampling program to support future drill
target generation activities.
The scale and number of pegmatite occurrences within the Eastern Brazilian Pegmatite Province and
proximal to the Caraíbas and Sidrônio projects is impressive. The prospectivity evaluation of the projects
has been confirmed and is considered high, supporting the Group’s desire to implement aggressive
exploration strategies to vector toward lithium rich areas.

REVERSE CIRCULATION DRILLING ON TENEMENT E63/2001
The maiden drill program at the Dundas South Project was successful in locating a felsic pegmatitic
hydrothermal system within E63/2001. Drilling was as a result of the identification of a lithium in soil anomaly
in January 2023 (ASX Announcement 23 January 2023) and intersected multiple pegmatites under cover.
12
Figure 5: Geological cross section ‘A’ - interpreted pegmatite after intersections in holes DSAC0031DSAC0034, and DSRC0029 and DSRC0030
Figure 6: Drill location map showing RC drill areas and intersected pegmatite locations
13
Results for lithium-caesium-tantalum (LCT) were subdued overall. Some minor but non-material elevations
in caesium, tantalum and tin are present in drill hole DSRC0029. These will form the basis of further review
which may determine future exploration activities within tenement E63/2001. Evaluation of results is
underway to determine a relevant strategy for targeting potential LCT pegmatite bodies concealed under
salt lakes to the north-west of the completed drilling. This area falls within the prospective Mt Kirk mafic
geological unit that transects the tenement in a north-north-west orientation.
The geological thesis for exploration within E63/2001 was that concealed LCT pegmatites may generate a
sufficient geochemical signature through the transported cover above to cause a geochemical response in
the soil. Previous exploration works by the Group utilising soil geochemistry identified lithium-rubidium insoil anomalies, these broadly coincide with the location of the pegmatites uncovered during drilling.
Additionally, geophysical targets interpreted from aeromagnetic interpretations further warranted drill
testing and formed the basis for drill targeting.
Future exploration in this area will continue to search for pegmatites of a similar fractionated
state/mineralised phase to those present at Liontown Resources’ (ASX: LTR) Buldania/Anna lithium deposit
to the north. The discovery of the unmineralised pegmatite bodies under cover, at the scale they have been
intersected downhole, is considered a positive indicator for the prospectivity for the tenement. Other areas
with similar transported cover within the tenement may also host similar pegmatitic hydrothermal fluid
systems without surficial expression, but within a geochemical setting more aligned with the nucleation of
lithium bearing minerals.
INFILL SOIL SAMPLING AND DRILLING ON TENEMENT E63/2001
Follow up infill soil sampling on tenement E63/2000 and E63/1993 identified an 8km2 lithium in soil
anomaly up to 218ppm Li. Infill soil sampling was completed based on previous positive geochemical
results for the tenements in March 2023 (ASX Announcement 23 March 2023). A total of 1,265 samples
were collected and submitted for laboratory analysis.
A 96 hole, 3,820m Aircore drill campaign was completed in February 2024 with assays returning elevated
lithium values on composite samples with peak results of 994ppm lithium. This confirms and increases the
tenor of the previously identified anomalism.
14
Figure 7: Dundas South tenement E63/2000 and E63/1993 showing UFF+ lithium soil geochemistry results
and recent Aircore drill collar locations (white)
Two drillholes (DSAC0140 and DSAC0151) intersected albite-quartz-muscovite pegmatites. This supports
the thesis that pegmatite producing hydrothermal systems are present and may support lithium enrichment
if the genetic lithological conditions are correct. Due to the pegmatite intersection, drillhole DSAC0151
was sampled at 1m intervals. Potassium to rubidium ratios (K/Rb) are encouraging for this intersection as
they may indicate that pegmatites in this location have experienced fractionation.

Amended Exploration Update Dalmas & Hiver Lithium Projects
A Binding Letter of Intent was signed in August 2023 for acquisition of the Dalmas and Hiver lithium projects
in James Bay, Quebec. The final Binding Agreement was executed in September 2023 (ASX
Announcement 27 September 2023).
DALMAS PROJECT
The Dalmas Project is located in the James Bay region of Quebec approximately 150km to the east of
Patriot Battery Metals’ (ASX: PMT) Corvette lithium Project and 45km to the east of Winsome Resources’
(ASX: WR1) Adina lithium Project. The project area consists of felsic intrusive lithologies which are
juxtaposed against greenstone and metasedimentary units. This geological setting is considered favorable
to host pegmatite emplacement and potential for lithium-caesium-tantalum (LCT) mineralisation. The
project covers an area of 47km2.
16
Very limited exploration has occurred within the tenement boundaries with 13 sites with geological
observations being recorded. Of these, 9 have been described as ‘pegmatitic’. All reported pegmatite
outcrops will be investigated during early exploration activities with an emphasis on ground truthing the
reported pegmatitic lithologies. The remaining four outcrop locations with historical mapping will also be
investigated, as three of these have site interpretations that include a coarse-grained description.
HIVER PROJECT
The Hiver Project is also located in the James Bay region of Quebec and covers an area of 32km2 and is
located approximately 4km from the Trans-Taiga Road highway. The project is adjacent to Megado
Resources’ (ASX: MEG) Cyclone lithium Project and in the proximity of multiple lithium exploration
opportunities. The project demonstrates an interpreted folded and faulted extensions of greenstone
lithology (Aquilon Group) against granites of the Tramont Suite, thus it is thought to provide a geologically
favorable host environment for potential hard rock LCT pegmatite style mineralisation.
The project also has one historical outcrop mapping location, recorded by Québec's Ministry of Natural
Resources and Forests (MERN) which describes a ‘pegmatitic lithology’ in the north of the tenement. It is
the opinion of the Group that the greenstone extension holds the most prospectivity for hosting potential
lithium bearing pegmatites based on other projects in the surrounding area. Historic mapping of the area
is sparse in nature, with one outcrop being described as a pegmatitic intrusion.

MULTIPLE TARGETS IDENTIFIED AT DALMAS AND HIVER PROJECTS
The Group completed multispectral analysis across both the Dalmas and Hiver projects in August 2023.
Multiple areas were identified with a total of 165 discreet multispectral targets for follow up field
investigations. The identified target areas extend up to 2.7km in strike on the Dalmas Project and 2.1km on
the Hiver Project.
SATELLITE MULTISPECTRAL ANALYSIS
Multispectral analysis can be used as a mineral exploration tool by accessing data collected by
specialised satellites. These satellites have instrumentation capable of measuring the spectral
response of outcropping lithologies at the surface of the earth. The data collected can be used to aid
early regional scale exploration by focusing early exploration efforts on areas that are more likely to
have the right geological conditions to support the target exploration commodity.
Both ASTER and Sentinel-2 multispectral data covering the Dalmas and Hiver projects has been
utilised to generate the target areas presented herein. These satellites collect thermal infrared, visible
near-infrared, and shortwave infrared data which has been processed following industry leading
techniques8. These methods have been developed to target outcropping LCT pegmatites at other
project areas, the learnings are then applied elsewhere for image and target generation.
18
For the purpose of targeting at the Dalmas and Hiver Projects the spectral signature of the known
outcropping lithium pegmatites at Winsome Resources’ (ASX: WR1) Adina and Jamar projects were
measured. The spectral response signature over known outcropping LCT pegmatite areas was used
as an analogue to aid exploration by identifying similar targets within the Project areas. The Adina
and Jamar projects can reasonably be considered to have desirable outcropping lithologies that are
appropriate analogues for targeting at the Dalmas and Hiver projects.

FIRST GROUND RECONNAISSANCE AT DALMAS AND HIVER PROJECTS
First pass ground reconnaissance works were completed at Dalmas and Hiver projects in October /
November 2023. The reconnaissance field program focusing on the areas of interest previously
identified successfully identified multiple instances of pegmatite outcrop, as well as pegmatite
19
boulders at surface. Initial visual assessment by field geologists suggest the mineral assemblages
present are commonly quartz-feldspar-biotite.
The field team identified potential Beryllium bearing minerals in outcropping pegmatites, (Green
mineral shown in red circle in Figure 15) which is considered a positive exploration indicator. Peak
results from the Actlabs whole rock laboratory analysis include 33ppm lithium, 7.3ppm caesium and
3.6ppm tantalum. The next stages of the exploration strategy are currently being assessed, including
potential collection of high-resolution Light Detection and Ranging topographic data collec
