CHAIRMANS’ LETTER
Dear Fellow Shareholders,
On behalf of the Board of Directors, it is my pleasure to present to you the 2024 Annual Report on what
has been a very busy 2024 for Litchfield Minerals Limited (Litchfield, or the Company), since listing on
the ASX.
Litchfield Minerals has rapidly initiated its efforts in delivering a carefully considered exploration program,
initially assessing the potential of the West Arunta tenement of Mount Doreen. As promised, the team hit
the ground running in March, shortly after listing.
The in-ground effort has included an initial reverse circulation and diamond drilling campaign based on
targets that were being developed during the IPO period, discovering the desired sulphide mineralisation
that now requires further assessment. The above-ground efforts have also been undertaken to
efficiently and effectively assess the Mount Doreen targets areas more broadly. As reported, the results
have confirmed large magnetic zones as well as complimentary significant gravity anomalies. The team
recently completed a Lithostructural review across Mount Doreen, a GAIP (Gradient Array Induced
Polarization) survey and have initiated a VTEM (Versatile Time Domain Electromagnetic) survey to
deepen our understanding of the geological context of our portion of the West Arunta province, with the
aim of providing insights to where our target mineralisation is optimal to be explored.
In addition to the above completed work, exploration efforts for uranium and thorium have focused on
ground-based scintillometer surveys, soil and rock chip sampling over radiometric target granites. The
forthcoming results of these analyses will guide our next steps in exploring Rare Earth Elements and
uranium potential.
The Board has continuously encouraged the team’s forward-thinking approach through the
implementation of these advanced geophysical techniques, to identify new high-priority targets. The
team's ability to integrate cutting-edge technology will ensure a deeper understanding of the geological
landscape and will be a basis for accelerating progress towards future discoveries.
Importantly to myself and the Board, the above field work has been completed with no lost time injuries,
no medical treatments and only one minor first aid case. Matthew Pustahya, our Managing Director, has
been keenly leading the way for a safe and harmonious workplace for our employees and all our
contractors. Matthew understands the need for small exploration camps to not only work safely, but also
the importance of working well together in order to achieve in-field efficiencies that our Company desires
for optimal programme delivery.
Acquiring additional leases to ensure the future exploration optionality for the Company. When
establishing the IPO, the company held the tenements of Mount Doreen and Lucy Creek, which totalled
approximately 1,180 km2
. Since listing, two additional leases have been applied for, a northern
extension to Lucy Creek (or Lucy Creek 2, ~800 km2
) and Yambah (~650 km2
). The extensive
exploration tenement across what will be 2,630 km2
of the Northern territory will provide the Company
with great optionality to determine the most productive effort to assess the mineral deposit viability during
successive exploration programmes. At Mount Doreen, our focus remains on exploring for base metals,
uranium, and rare earth mineralisation. The benefit of obtaining additional tenement will allow the
Company to expand exploration effort into the increasingly important manganese potential across the
1,600 km2
of the Lucy Creek tenements near the Northern territory / Queensland border. In addition, we
now have Yambah, which is only 70 km north of Alice Springs and came with already mapped mafic
units that indicated it is a promising site for various mineral styles.
As a new company, we conscientiously living by the Oscar Wilde phrase of, “you never get a second
4
chance to make a first impression”. We have demonstrated this through how our interactions must
continuously be meaningful across the breadth of our stakeholders, such as our local Northern Territory
communities, our regulators our hard-working contractors and, importantly, our shareholders. We are
determined to develop and maintain excellent relationships across all external stakeholders with the
efforts we are undertaking. This can be seen through the content and frequency of keeping people
updated with our ASX announcements. I will ensure that this importance of good communications does
not abate.
In summary, during the short history of our company, with the key support the shareholders, we have
already made significant strides in 2024, towards our goal of discovering and developing new mineral
deposits in the Northern Territory. I firmly believe that our team’s proactive and results-driven approach
underscores Litchfield's commitment to delivering value for shareholders.
Yours sincerely
Dr Peter Eaglen
Non-executive Chairman

REVIEW OF OPERATIONS
Litchfield Minerals holds a portfolio of exploration assets in the Northern Territory, highly prospective for
base metals, manganese, rare earths, and uranium. This portfolio includes two granted tenements—
Mount Doreen (EL31305) and Lucy Creek (EL33568)—as well as two exploration applications for
Yambah (EL33889) and Lucy Creek 2 (EL33888), covering a combined area of nearly 2,600 square
kilometres.
Figure 1. Litchfield Minerals Pty. Ltd. projects within the Northern Territory.
Mt Doreen Project (100% Owned, EL31305)
• Primary focus in FY2024 was completing geophysics and drilling of historic base metal prospects
(refer to Figures 2 and 3).
• A detailed aeromagnetic survey (100m and 50m line spacing) was completed over the northern
tenement block (300km2
, 4,222 line km). This data significantly increased resolution over
historical surveys (400m line-spacing) and is a critical dataset that will be used to complete a
detailed lithostructural interpretation early in FY25
• During FY24, Gradient Array Induced Polarization (GAIP) surveys were completed at Mt Irene
(0.8km x 1.5km) and Wolfram Hill (1.1km x 1.5km)
• Pole-Dipole Induced Polarization (PDIP) was completed at Mt Irene (1.1km single line) and
Wolfram Hill (4 lines, 3,750m)
6
• Induced Polarization surveys identified a +25mV/V chargeability anomaly at Mt Irene and multiple
+15mV/V chargeability anomalies at Wolfram Hill beneath historical workings
• Ground-based scintillometer data was collected over the Uranium and Thorium-enriched granites
east of Silver King to help define zones of radiometric anomalism (1,643 samples, 27.4 line km)
• RC and diamond drilling at Silver King, Mt Irene and Copper Flats (north Wolfram Hill) produced
a combined total of 1,769 meters drilled over 12 drill holes (results announced 14th
August 2024)
• Soil (104 samples) and rock chip sampling (25 samples) were completed over radiometric ‘hot’
granites northeast of Wolfram Hill and east of Silver King to assess REE mineralization potential.
An additional 28 rock chip samples were collected over the mineralized zones at Wolfram Hill
(awaiting results)

Key Exploration Targets:
• Silver King: A mineralised zone within quartz-muscovite schist, showing potential for polymetallic
mineralisation (copper, lead, zinc and silver).
• Mount Irene: Copper, zinc and silver occurrences within quartz-veined shears with high
chargeability anomalies identified through induced polarization geophysical surveys.
• Clark: Copper mineralisation in quartz-veined shear zones with historical workings showing
promising results.
• Wolfram Hill: Tungsten and copper mineralisation associated with pegmatite and quartz veins,
with historical production of wolframite.
Exploration Work Since IPO:
Aeromagnetic Survey
During March 2024, MagSpec Airborne Suveys completed a detailed aeromagnetic survey over the
northern block of the Mt Doreen EL31305 (Figure 4). A total of 4,222 line kilometres were completed
covering approximately 300km2
. The entire survey was flown at 100m line-spacing and additional 50m
lines were completed over the Mt Irene/Clark and Silver King prospects (Table 1). Data was stitched into
the Rio Tinto Exploration 1997 Annie Springs survey (covered southern block of EL31305) to produce a
series of magnetic images that cover all of EL31305. This new aeromagnetic survey has produced a
high-resolution dataset that will be critical for lithostructural geological interpretation of EL31305 that is
scheduled for completion in Q1 FY25.

survey (northern EL31305 block) with the 1997 Rio Tinto Annie Springs survey (southern EL31305 block).
Gradient Array Induced Polarization Surveys
Mt Irene
An 800m x 1,500m gradient array IP (GAIP) survey was completed at the Mt Irene prospect (Figure 5) to
extend the 2023 survey and to cover a strong (25mV/V) chargeability anomaly identified in the 2023
Pole-Dipole IP survey (Figure 6). GAIP chargeability data shows a continuation of the main west-
northwest trending Mt Irene structural trend and an east-northeast trending linear chargeability feature
was also identified. The Mt Irene workings, the northwest GAIP and western PDIP chargeability
anomalies were all targeted with RC drilling during May to June 2024.

Wolfram Hill / Copper Flats
Gradient Array Induced Polarization (1,100m x 1,500m) and four lines of Pole-Dipole IP were completed
at Wolfram Hill in April 2024 to cover the main historical workings and surrounding shallow alluvial cover
(Figure 7). The PDIP data identified a strong chargeability anomaly in the eastern parts of the sections,
however, it was interpreted that this response was most likely attributable to the barbed wire fence
surrounding the air strip (Figure 8). Two main GAIP chargeability anomalies were identified, one in the
southwest of the survey corresponds well with exposed historical workings and the other to the northeast
of the survey runs along the western side of the air strip. Litchfield Minerals currently does not have
access to drill beneath the historical Wolfram Hill workings due to on-going negotiations with the
Aboriginal Areas Protection Agency and so the northeastern chargeability anomaly (named Copper
Flats) was tested with two RC drillholes during the inaugural drilling campaign (LMRC005/006, see
drilling section below). Pole-Dipole IP produced +15mV/V chargeability anomalies coincident with
historical workings (Figure 9) and formed coincident anomalies with the Gradient Array IP data.

Drilling Campaign Summary
Litchfield's inaugural drilling campaign targeted three prospects within the Mt Doreen project (Silver King,
Mt Irene, Copper Flats, Figure 10) with twelve holes for a total 1,769m (1,006m RC, 763m DD, Table 2).

Silver King
At Silver King (Figure 11), six holes were drilled (1,061.37m) comprising four RC holes with diamond
tails, a single diamond hole and a single RC hole (296.6m RC / 764.7m DD). Holes were designed to
test the extension and geometry of base metal mineralisation beneath exposed historical workings.
Drillholes LMD001 and LMRD002 (Figures 12, 13) intersected a thick package of metamorphosed fine-
grained sedimentary rocks (Lander Rock Formation) intruded by a swarm of narrow, feldspar-quartz-
muscovite pegmatites. Mineralised intervals are characterized by base metal sulphide veins and minor,
narrow zones of semi-massive and massive sulphide (pyrite, sphalerite, galena, chalcopyrite, pyrrhotite).
Mineralisation is commonly accompanied by varying degrees of pervasive silica-sericite wallrock
alteration and associated disseminated sulphides.

Cu-Pb-Zn intersected in LMD001.
Figure 13. Schematic cross-section (7552275mN looking north) showing several narrow zones of base metal
mineralization intersected in LMRD002.
15
LMRD003 was drilled to the northeast to intersect both the targets identified by the Induced Polarisation
(IP) chargeability and magnetic models (Figures 11, 14). Drilling intersected an identical host sequence
to LMD001/LMRD002, comprising metasandstone and metasiltstones of the Lander Rock Formation,
punctuated by narrow, coarse-grained quartz-feldspar-muscovite pegmatites (<1m).
Base metal sulphide mineralisation was intersected almost continuously from surface to 64.3m (57m @
0.32% combined Cu-Pb-Zn), comprising zones of disseminated pyrite-chalcopyrite-sphalerite (0.5 – 5%
total sulphides, 24 – 35m), pyrrhotite-sphalerite-chalcopyrite veinlet crackle breccia (0.5 – 5% total
sulphides), with associated weak to moderate pervasive wallrock silicification all cut by 1%, late, brittle
chlorite ± pyrite veins (Table 2).
Figure 14. Schematic cross-section of LMRD003 (looking northwest), showing a broad interval of combined +0.1%
Cu-Pb-Zn with several narrow zones of elevated mineralisation.
LMRD004 was drilled through Lander Rock Formation to the south to test the coincident IP-magnetic
models (Figure 15) and intersected the strongest mineralisation from the five Silver King holes (Table 2).
The upper mineralised zones are associated with disseminated, veinlet and crackle breccia sphalerite-
pyrite-galena-chalcopyrite±pyrrhotite mineralisation, with weak- to moderate silica-sericite wallrock
alteration. Sulphide content varies throughout the interval but ranges from 1 – 15% sphalerite, 1 – 4%
pyrite and minor to trace galena, chalcopyrite, pyrrhotite over 1m intervals. The lower mineralised zone
is characterised by generally weak disseminated and veinlet sulphides (<2%), with weak to moderate
silica-sericite wallrock alteration, punctuated by two narrow zones of semi-massive and massive
sphalerite-galena-pyrrhotite-pyrite±chalcopyrite at 51m and 64m (Figure 16a). Mineralisation shows a
complex, multi-phase paragenesis with early massive pyrrhotite-sphalerite chalcopyrite cut by later
massive galena-sphalerite (Figure 16b).

and below the redox zone.

17
LMRC007 (181m) was drilled east away from the main Silver King prospect into the interpreted eastern
extension of the main IP chargeability anomaly and intercepted unmineralised Lander Rock Formation
throughout. LMRD008 (261.2m) was collared 470m north of Silver King and drilled to the south into a
peripheral, low-magnitude IP chargeability anomaly. The hole was partly funded by the Northern
Territory government. This hole also drilled unmineralised Lander Rock Formation throughout and
together with LMRC007 effectively sterilised the low chargeability anomalies surrounding the main target
of the Silver King prospect.
At Silver King, there is a broad correlation between observed sulphides in core and modelled
chargeability / magnetic susceptibility, indicating that these two geophysical techniques are suitable for
detecting and modelling Silver King-type mineralisation. The Pole-Dipole IP chargeability sections,
particularly 725300mE, shows a shallow-rooted, weakly concave geometry that shows a good correlation
with observed sulphides in drill core. Mineralization identified in LMRD004 indicates that Silver King-type
systems have the capacity to produce semi-massive and massive sulphides and similar mineralized
zones are likely to be identified within the upcoming airborne EM survey (VTEM) scheduled for
completion in Q1 FY25.
Copper Flats
Two, 150m RC holes (LMRC005, LMRC006, Figure 17) were completed at the Copper Flats prospect
on the northeastern chargeability anomalies (Table 2, Appendix 1 - 5). Drilling intersected
metamorphosed sediments of the Lander Rock Formation and multiple narrow pegmatites but did not
intersect any meaningful mineralized zones. This data potentially confirms the interpretation that the
northeastern GAIP chargeability anomaly is caused by the fence surrounding the air strip.
Figure 17. Aerial image of Wolfram Hill overlain by FY24 Gradient Array IP Chargeability image showing the
correlation between historical workings and chargeability and the proximity of the northeastern anomalies to the
western side of the air strip (LMRC005, 006).
18
Mount Irene
At Mt Irene, four RC holes were drilled (LMRC009 – LMRC012, 408m, Table 2) with, two drilled
underneath the historical Mt Irene copper prospect (LMRC009/010). LMRC011 was drilled to target the
northern Gradient Array IP chargeability anomaly and LMRC012 was drilled to test the westerly Pole-
Dipole IP chargeability anomaly.
LMRC009 and LMRC010 (Figures 18, 19) were both drilled to target the down-dip extension of
outcropping mineralisation at the Mt Irene prospect. Both holes intersected narrow (1 – 5m) quartz-
malachite / gossanous mineralisation in the interpreted down-dip position below small-scale historic
mining pits. Mineralisation is hosted within schistose Lander Rock Formation within a structurally-
controlled quartz vein lode. The presence of malachite and minor gossanous zones is indicative of
supergene leaching and copper mobility.
LMRC011 was drilled to test a gradient array IP chargeability anomaly approximately 450m along strike
to the northwest of the historic Mt Irene mining pits. Drilling intersected Lander Rock Formation
throughout with several unmineralized milky quartz veins and narrow pegmatites. The hole was
terminated before the target depth (220m) due to excessive water and limited sample return.
LMRC012 was drilled to target a strong chargeability anomaly (peak 25mV/V, almost double Silver King,
Figure 20) in the single pole-dipole line. Additional lines were planned, however, unseasonal heavy
rains forced the early completion of the program.
The drillhole intersected Lander Rock Formation throughout that is oxidized to end of hole, indicating a
very deep weathering profile, most likely relating to a well-developed NNE-trending structure.
Unfortunately, the hole was terminated early at 162m (250m planned depth) due to excessive water and
inadequate sample return. Trace limonite and rare disseminated chalcopyrite was observed below
100m, however, no +0.1% Cu-Pb-Zn assays were returned. Additional pole-dipole lines are required to
refine the geometry of this chargeability anomaly.

Prospective Mineralisation Models:
• Epigenetic Intrusion-Related Breccia and Vein Mineralisation: Potential for polymetallic
mineralisation.
• Iron-Oxide Copper-Gold (IOCG) Related Mineralisation.
• Carbonatite/ Rare Earths.
• Orogenic Gold Mineralisation.
• Syngenetic Base Metal and Precious Metal Mineralisation.
• Sandstone-Hosted Uranium Mineralisation.
Conclusion:
The Mount Doreen project is a well-advanced exploration asset with significant potential for discovering
economically viable mineral deposits. The historical data, combined with Litchfield’s recent exploration
efforts, provide a strong foundation for continued exploration. The project is strategically focused on
high-priority targets with the potential for multiple mineralisation styles, making it a key component of
Litchfield’s exploration portfolio.

Lucy Creek and Lucy Creek 2 Project Overview (100% Owned, EL33568 and ELA33888)
Figure 21. Lucy Creek Project tenement location map.
Exploration Model - Manganese
Lucy Creek area has the potential to host a manganese deposit similar to the Bootu Creek Manganese
Mine. Located approximately 110 km north of Tennant Creek in the Northern Territory, Bootu Creek is a
significant manganese deposit within the Tomkinson Province. Discovered and developed by OM
Holdings Ltd. through its subsidiary OM (Manganese) Ltd, the mine commenced operations in 2005 and
remained active until December 2021, when it was placed under care and maintenance. The geological
characteristics and mineralization processes observed at Bootu Creek provide a strong analogue for
what might be expected at Lucy Creek.
Key Geological Features (Bootu Creek Model):
• Deposit Type: The Bootu Creek deposit is a hydrothermally modified sedimentary deposit,
primarily hosted in Palaeoproterozoic rocks of the Tomkinson Province. The manganese
mineralization is stratabound, occurring at the contact between the Attack Creek Formation
(dolomite-siltstone) and the overlying Bootu Formation (sandstone).
• Associated Structure - The mineralized zones are associated with a folded structure, known as
the Bootu Syncline, which plays a crucial role in controlling the distribution of manganese.
22
• Mineralization: The manganese mineralisation at Bootu Creek is predominantly supergene
enriched within a deeply weathered profile. The main manganese minerals include Pyrolusite and
Cryptomelane in a silica-rich gangue within the supergene zone, overlying a zone of
Rhodochrosite and Braunite at depths greater than 90 meters.
• Resource Size: The Bootu Creek resource models have a combined strike length of 16 km, with
individual deposits ranging from 0.7 km to 2.9 km in length. The mineralization widths vary
between 3 meters and 15 meters.
Lucy Creek Exploration Focus:
• Manganese and Iron Deposits: The Lucy Creek area is known for its manganese occurrences,
particularly within the Tomahawk Formation, where manganese is associated with dolomitic
siltstones. There is potential for high-grade manganese-iron deposits, possibly associated with
REE and cobalt mineralisation.
• REE Mineralisation: The area may be prospective for REE mineralisation associated with
carbonate-hosted phosphate-bearing horizons within the Georgina Basin sequence.
• MVT Base Metal Mineralisation: Potential for Mississippi Valley Type (MVT) base metal
deposits, which are stratiform, sediment-hosted, primarily lead and zinc.
• Kimberlitic Diamond Mineralisation: The geological setting is considered prospective for
diamonds, with the Altjawarra Block beneath the Georgina Basin being a potential source of
kimberlitic diamond pipes.
Proposed Exploration Work 2025:
• Exploration Focus: Litchfield intends to explore the Lucy Creek area for high-grade manganese,
REE, base metals, and diamonds. The exploration program is expected to include geological
mapping, geochemical sampling and geophysical surveys to identify and define drill targets.
Key Opportunities:
• Strategic Potential: The Lucy Creek project offers a diverse range of exploration opportunities
with the potential for discovering commercially viable manganese, REE, base metal and diamond
deposits.
• Proximity to Known Deposits: The project is located within a region known for its mineral
endowment, providing a strong geological basis for continued exploration efforts.
Conclusion:
The Lucy Creek project represents an exciting early-stage exploration opportunity within the Georgina
Basin, a region known for its diverse mineralisation potential. With a strategic focus on manganese,
REE, base metals and diamonds, the project has the potential to contribute significantly to Litchfield’s
exploration portfolio. Continued exploration and successful tenure acquisition will be critical to unlocking
the project’s full potential.
23
Yambah Project (100% Owned, ELA33889)
• ELA33889 was applied for during FY24 to target base metal sulphides within under-explored
mafic/ultramafic intrusive rocks (Figure 22).
Figure 22. Yambah Project tenement location map.
Exploration Focus:
• Continued focus on detailed geological mapping and further rock chip sampling to better define
the extent and grade of copper mineralisation.
• VTEM Survey designed to test the tenement package for massive sulphides.
• Potential for drill testing to explore below the surface expression of the mineralisation, particularly
targeting the pyroxenite body and its surrounding structures.
Conclusion:
The Tom Brauns Prospect represents a significant exploration target within the Yambah Project, with
strong indicators of copper mineralisation. The presence of high-grade copper, alongside zinc and silver
anomalies, warrants further exploration efforts. Continued work at Tom Brauns, particularly at the Tom
Brauns II occurrence, could lead to the discovery of a commercially viable copper deposit, contributing to
the overall exploration success of the Yambah Project.
