ASX ANNOUNCEMENT 30 September 2026
Surface Copper Strengthens Exploration
Targets
Copper-bearing minerals at surface sharpen the focus on large Sybil EM conductors and
the Illogwa Creek structural corridor
Litchfield Minerals Limited (ASX: LMS) (“Litchfield” or “the Company”) reports an important step
forward in its Harts Range Project, with September field reconnaissance identifying copper-bearing
minerals at Sybil and sulphide-bearing mafic rocks near a priority electromagnetic (EM) target at Illogwa
Creek. The observations strengthen the case for follow-up ground EM to test for copper-bearing
sulphide systems below surface.
The targets were identified through the Company’s review of historical airborne EM surveys and
exploration records. At Sybil, visually identified chalcopyrite and nearby copper carbonate staining
provide a clear focus around the large modelled P4 conductor.
At Illogwa, the combination of sulphide-bearing mafic rocks, an untested conductor and an interpreted
deep structural corridor provide a compelling target for the Company’s broader orthomagmatic copper-
nickel exploration model.
H I G H L I G H T S
▪ Copper-bearing minerals observed in the Sybil P4 target area, with visually identified
chalcopyrite and nearby malachite staining.
▪ P4 is modelled at approximately 400m long and 200m wide, providing a sizeable, modelled
conductor for ground EM follow-up.
▪ Sulphide-bearing mafic rocks near Illogwa anomaly 26, together with an interpreted deep
structural corridor, define a priority copper-nickel exploration target.
▪ Ground EM is being organised across priority targets. Nineteen rock chip samples, together
with a standard and a blank, have been sent to the laboratory, with assays expected in
approximately three to four weeks.
Visual mineral identifications are preliminary. They do not establish copper grade, mineralised continuity or economic
significance, and are subject to laboratory confirmation.
Cautionary statement: Visual estimates of mineral abundance should never be considered a proxy or substitute for
laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also
potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. The mineral
descriptions in this announcement are visual field observations only. Samples have been submitted to the laboratory, and
assay results are expected in approximately three to four weeks.

Managing Director Matt Pustahya said:
“Finding copper-bearing minerals at surface in these large, modelled EM conductors is an exciting step
forward for Litchfield. At Sybil, we have visually identified chalcopyrite in the P4 target area and
malachite nearby. Together, these observationsgive usa stronger geological basisto pursue the copper
potential below surface and sharpen our next phase of exploration.
Illogwa Creek is one of the areas we are most excited to advance. Our interpretation developed through
BHP Xplor points to a deep structural corridor that may have provided a pathway for mantle-derived
magmas. What makes this target compelling is the combination of that setting, sulphide-bearing mafic
rocks and a priority EM conductor. That is a strong reason to test our wider copper-nickel model.
We are eager to get ground EM across Illogwa and the priority Sybil targets. Our focus is to resolve the
conductors, integrate the pending assays and turn these opportunities into well-defined drill targets.
There is more work to do to establish what is driving the EM responses, and we now have a clear set of
priorities to pursue.”
Surface copper strengthens the case for testing large Sybil conductors
Sybil lies within EL34245, approximately 33.6 kilometres southeast of Oonagalabi. Following the licence
grant and the Company’s initial desktop review, fieldwork examined the geology around historical VTEM
conductor areas and rock chip locations (Figures 1, 2 and 5).
Mitre Geophysics conducted a preliminary assessment of the historical VTEM data, identifying seven
modelled conductor plates, several of substantial scale. Their approximate dimensions, expressed as
along-strike length by down-dip extent, are:
• P5: 1,200m × 1,200m
• P2: 800m × 300m
• P1: 600m × 300m
• P4: 400m × 200m
• F1: 300m × 100m
• P3: 100m × 50m
• P6: 25m × 25m
These preliminary modelled dimensions highlight the scale of the targets, with further exploration
required to determine their geological source.
The strongest field observations were recorded in the P4 area, where garnet-bearing amphibolite
contains fine disseminated sulphides visually identified as chalcopyrite and pyrite (Figure 1). Sample
SYB-04 was collected from quartz- and garnet-rich rock, with sulphides observed within and around
garnet porphyroblasts (Table 1b). The preliminary P4 conductor plate is modelled at approximately 400m
long and 200m wide, dipping at 20 degrees, providing a sizeable geophysical target for follow-up ground
EM. These are interpreted conductor dimensions; the presence and dimensions of any mineralised body
remain to be established.
Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 3 of 18
Northwest of P4, the field team identified malachite staining along a faulted contact between felsic
gneiss and altered amphibolite. The host outcrop was traced for approximately 50m, with the copper-
bearing zone locally 0.5–1m wide at surface. Continuous copper mineralisation over the mapped extent
and true width have not been established. Samples SYB-07 and SYB-08 were collected from the altered
unit and an adjacent vein, respectively (Table 1b and Figure 5; Appendix A).
Surface copper-bearing minerals and the large modelled P4 conductor make this area a priority for
ground EM. The survey will refine conductor geometryand helpassess whetherthe surface observations
relate to conductive sources at depth. The source, grade and extent of any subsurface mineralisation
remain unconfirmed.

inspection; their identity and abundance cannot be determined from this photograph. Mineral identifications are provisional and
no grade is implied.
Cautionary statement: Visual estimates of mineral abundance should never be considered a proxy or substitute for
laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also
potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. The mineral
descriptions in this announcement are visual field observations only. Samples have been submitted to the laboratory, and
assay results are expected in approximately three to four weeks.

small grey squares are the historical Mithril Resources VTEM anomaly positions. Mineral identifications are visual field
observations and hence are provisional and subject to laboratory confirmation; no assay results are reported.
Illogwa Creek brings together a priority conductor and a deep structural target
Reconnaissance near historical AEM anomaly 26 at Illogwa Creek identified sulphide-bearing mafic rocks
within altered felsic gneiss along the Illogwa Creek Shear Zone (Figure 3). Pyrite, chalcopyrite and
possible pyrrhotite were observed. The team traced a mafic intrusion for approximately 200m length,
and noted foliated and less-deformed rocks with local iron oxidation, silica alteration and moderate to
strong magnetism. Rock chip samples ILG-05 to ILG-08 cover the principal sulphide-bearing exposures
(Table 1b; Appendix A). This mapped extent describes the geological zone and does not establish
continuous mineralisation.
Research and interpretation undertaken by Litchfield (in conjunction with the BHP Xplor program)
suggest the Illogwa Creek Shear Zone may extend into the deep crust and potentially connect with
mantle-derived magmatic pathways. Such a structure could have helped channel mafic magma into the
crust,making thecorridoran attractive setting to investigate for orthomagmatic copper-nickel systems.
The depth extent and mantle connection remain interpretations to be tested.

Figure 3. Regional magnetotelluric section along seismic line 09GA-GA1 (after Vox Geophysics, 2026), showing the interpreted
down-dip continuation of the Illogwa Creek Shear Zone towards C1, a conductive zone in the lowermost crust. The shear zone label
and C1 callout are Litchfield annotations. Magnetotelluric models are non-unique, resolve crustal-scale features only, and do not
demonstrate the presence, grade or economic significance of mineralisation.
Orthomagmaticcopper-nickel systems form whenmantle-derivedmagma becomes sulphide-saturated,
and a separate sulphide liquid collects copper, nickel and other metals. Accumulation of these sulphides
can form mineralised deposits. Trace sulphides alone are common in mafic rocks; at Illogwa, the
exploration opportunity comes from their occurrence near an untested EM conductor within the
interpreted deep structural corridor (Figure 4). Together, these features provide a compelling basis for
ground EM and further testing of the model. A magmatic origin for the observed sulphides has not yet
been established.
Potassic and epidote alteration was reported at localities extending up to approximately 1km from the
surface expression of the conductor, with localised silica, sericite, chlorite and possible actinolite
alteration around the mafic rocks. The alteration also leaves open a hydrothermal contribution or later
overprinting. Follow-up ground EM and assessment of the samples will help test how the surface
sulphides, host rocks and alteration relate to the EM response.

Visual mineral observations
Table 1b (Appendix A) reports the visual mineral observations from the September 2026 surface rock chip
sampling at Sybil and Illogwa, in line with ASX Guidance Note 8 (with sample locations shown in Figure 5).
Observations are from outcrop and rock chips only; no drilling has been undertaken. Abundances are
visual field estimates of the proportion of each mineral in the sampled rock. Laboratory assay results for
the 19 rock chip samples sent for analysis are expected in approximately three to four weeks and will be
reported when received. Full sample descriptions and coordinates are listed in the sample and
observation register (Table 1a, Appendix A), and JORC Code (2012) Table 1 information is provided in
Appendix B.
Next steps
Litchfield is organising follow-up ground EM surveys over Illogwa anomaly 26 and the priority Sybil
targets. Nineteen rock chip samples, comprising 12 from Sybil and seven from Illogwa, have been sent
to the laboratory together with a standard and a blank, with results expected in approximately three to
four weeks. The Company will integrate assay results, surface mapping and refined conductor models
to select potential drill targets. At Illogwa, a key objective is to test whether the surface sulphides relate
to a larger conductive source below surface.
Future drilling will depend on target definition, terrain and access planning, and heritage, environmental
and regulatory requirements.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
Criteria JORC Code explanation Commentary
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.
• Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any
measurement tools or systems used.
• Aspects of the determination of
mineralisation that are Material to the
Public Report.
• 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.
September 2026 reconnaissance involved geological
traverses, inspection of historical EM target areas and
rock sampling. The register records 22 locations and 19
rock chip samples sent to a laboratory, submitted with
one standard (ILG-02Q) and one blank (SYB-03Q) (21
samples in total). SYB-01 is from a historical mica-
trench mullock heap; other records describe rock
exposures. Rock chip samples were collected as grab
samples from outcrop and subcrop, using a geological
hammer to take fresh rock across the exposed lithology
or mineralised zone. No subsampling or preparation
was undertaken in the field; each sample was bagged,
numbered and submitted to the laboratory as whole
rock. All sample preparation will be completed by the
laboratory in accordance with its standard procedures.
The sample size is considered appropriate for the
reconnaissance nature of the sampling. No field
duplicates were collected, as the sampling is selective
and not intended to be representative of grade. No
assay results are reported in this announcement.
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 results are reported in this announcement.

recovery and ensure representative nature
of the samples.
• 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.
Not applicable. No drill samples are reported.
Logging • Whether core and chip samples have

confirmation is not reported.
Subsampling
techniques and
sample preparation
• If core, whether cut or sawn and whether
quarter, half or all core taken.
• If non-core, whether riffled, tube
sampled, rotary split, etc and whether
sampled wet or dry.
• For all sample types, the nature, quality
and appropriateness of the sample
preparation technique.
• Quality control procedures adopted for all
sub-sampling stages to maximise
representivity of samples.
• 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.
• Whether sample sizes are appropriate to
the grain size of the material being
sampled.
The sample register identifies 19 rock chip samples

one blank (SYB-03Q) into the submission, in addition to
Bureau Veritas’ internal laboratory quality control. No
laboratory assays or quantitative portable XRF
readings are reported in this announcement. Visual
sulphide observations are not estimates of metal
grade. Historical airborne EM data (Mithril Resources
VTEM surveys, 2010 and 2011; Western Desert
Resources REPTEM survey, 2010) were acquired and
processed by previous explorers, with system
parameters as reported in open-file reports CR2010-
0516, CR2011-0836 and CR2011-0091. Litchfield has not
independently verified the acquisition or processing of
these data. Historical EM responses provide targeting
context only; no new ground EM survey result is
reported.
Verification of
sampling and
assaying
• The verification of significant
intersections by either independent or
alternative company personnel.
• The use of twinned holes.
• Documentation of primary data, data
entry procedures, data verification, data
storage (physical and electronic) protocols.
• Discuss any adjustment to assay data.
No independent analytical verification of the visual
mineral identifications is reported. Historical sample
locations recorded as 60847 and 60849 were revisited
without reproducing the reported mineralisation.
Their source records, positioning and sample context
require reconciliation. No assay adjustments have
been made because no new assay data are reported.
