Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 2 of 20 OVERVIEW Litchfield Minerals Limited (ASX: LMS) (“Litchfield” or “the Company”) is pleased to provide its Quarterly Activities Report for the period ended 30 September 2026. During the September 2026 quarter, Litchfield advanced field validation of its Harts Range targets following the grant of EL34245,4 completed an initial three-line IP survey at Silver Valley, released the final assays from the Phase 3 Oonagalabi drilling program and prepared to return to drilling at the Oonagalabi Main Zone. Operations Overview The September quarter moved several of the Company’s exploration opportunities from regional interpretation to targeted field investigation, guided by the mineral systems framework developed through BHP Xplor. Following the grant of EL34245, the Company commenced field reconnaissance across the historical Sybil VTEM conductor areas and the Illogwa Creek structural corridor. Copper-bearing minerals were visually identified at surface at Sybil, and sulphide-bearing mafic rocks were identified near a priority EM conductor at Illogwa Creek, providing a clear set of priorities for follow-up ground electromagnetic (EM) surveying. At Silver Valley, an initial three-line IP survey identified modest western chargeability responses but did not delineate a discrete high-priority drill target. The Company paused the survey after three lines to integrate the results with field mapping and reassess the positioning of the remaining lines towards the western side of the system.5 At Oonagalabi, the Company secured a drill rig throughTopdrill andmobilised a dozer to preparedrill pads ahead of an October drilling program designed to build on the broad copper-zinc mineralisation intersected at the Main Zone during Phase 3.6 Harts RangeProject, Northern Territory EL34245 Granted, Unlocking the Sybil Copper Target Exploration Licence EL34245 (Harts Range 1), covering approximately 384km², was granted on 30 July 2026.7 The licence allows Litchfield to advance the Sybil copper target, an undrilled target identified through historical exploration by Mithril Resources in the Lizzie Creek area and reassessed as part of the Company’s belt-scale review of Harts Range. Sybil is located approximately 33.6km south-east of the Oonagalabi Project (Figure 1). 4 LMS ASX Announcement, LMS ASX Announcement, New Harts Range Licence Unlocks Priority Sybil Copper Target, dated 20 August 2026. 5 LMS ASX Announcement, Silver Valley IP Survey Identifies Western Anomalies, 10 August 2026 6 LMS ASX Announcement, LMS Secures Rig to Start October Drilling at Oonagalabi, 24 September 2026 7 LMS ASX Announcement, New Harts Range Licence Unlocks Priority Sybil Copper Target, 20 August 2026 Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 3 of 20 Historical exploration identified an airborne electromagnetic (VTEM) response at Sybil and reported surface rock chip results of up to 0.9% Cu and0.1% Zn,with no previous drilling identified in the historical information reviewed. Litchfield’s compilation of historical and regional datasets places the target within a broader gravity response and a favourable geological and structural setting, with multiple independent datasets supporting follow-up. Sybil occurs within the Riddock Amphibolite, the same broad geological unit that hosts the third-party Basil copper-cobalt deposit, located approximately 24.6km east of Sybil. Figure 1. Sybil tenement setting within the Company’s Harts Range tenure, showing Sybil relative to the Oonagalabi Project and the third-party Basil, Baldrick and Blackadder deposits and prospects. Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 4 of 20 Field Reconnaissance Identifies Surface Copper at Sybil Following the licence grant, September fieldwork examined the historical VTEM conductor areas and rock chip locations at Sybil.8 Mitre Geophysics modelled seven preliminary conductor plates from historical VTEM data, including P5 (approximately 1,200m × 1,200m), P2 (800m × 300m) and P1 (600m × 300m). These dimensions describe modelled along-strike length and down-dip extent, not the size of mineralisation. The strongest field observations were recorded in the P4 area, where garnet-bearing amphibolite contains fine disseminated sulphides visually identified as chalcopyrite and pyrite (sample SYB-04). The preliminary P4 conductor plate is modelled at approximately 400m long and 200m wide, dipping at 20 degrees. Northwest of P4, malachite staining was identified along a faulted contact between felsic gneiss and altered amphibolite (Figure 2), 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. Figure 2. Sybil field photograph showing green copper carbonate staining. Disseminated sulphides were recorded during field inspection; their identity and abundance cannot be determined from this photograph. Mineral identifications are provisional and no grade is implied. 8 LMS ASX Announcement, Surface Copper Strengthens Exploration Targets, 30 September 2026 Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 5 of 20 Other Sybil traverses recorded no notable visible mineralisation at F1, P3 or historical VTEM anomaly 42, minor to trace sulphides at P1 and P5, and iron-stained garnet-bearing amphibolite at anomaly 41 (Figure 3). Two historicalrock chip locations were revisitedand the reportedmineralisation was not reproduced. Figure 3. Sybil rock chip locations from the September 2026 sample register plotted over the preliminary modelled EM conductor plates on a regional gravity background, shown as a zoomed-out view of the Sybil conductor plate area (left) and a zoomed-in view of the P4 priority area (right). Coloured polygons are the conductor plates modelled by Mitre Geophysics from historical VTEM data; 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. The Sybil exploration results referred to above are historical in nature and are subject to the disclosures in the Company’s announcement of 20 August 2026, including the JORC Code (2012) Table 1 provided in Appendix A of that announcement. The information is limited to that available from historical records, has not been verified to the current JORC Code and should not be relied upon for Mineral Resource estimation or economic evaluation. Basil is located on third-party tenure, and Litchfield has no ownership interest in the deposit. The geological association between Sybil and Basil does not demonstrate that similar mineralisation is present at Sybil. Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 6 of 20 Illogwa Creek Brings Together a Priority Conductor and Deep Structural Target Reconnaissance near historical airborne EM anomaly 26 at Illogwa Creek, also within EL34245, identified sulphide-bearing mafic rocks within altered felsic gneiss along the Illogwa Creek Shear Zone (Figure 4).2 Pyrite, chalcopyrite and possible pyrrhotite were observed, and a mafic intrusion was traced for approximately 200m. This mapped extent describes the geological zone and does not establish continuous mineralisation. Figure 4. Illogwa field exposures examined during reconnaissance around the priority EM target, where mafic rocks and alteration were mappedand sampled. Thesephotographs illustrate outcropcontext;mineral identifications relyon field inspection and remain provisional pending laboratory confirmation. Left: sample ILG-06; right: sample ILG-02. Interpretation developed by Litchfield through the BHP Xplor Program suggests the Illogwa Creek Shear Zone may extend into the deep crust and potentially connect with mantle-derived magmatic pathways, making the corridor an attractive setting to test the Company’s orthomagmatic copper-nickel exploration model (Figure 5). The depth extent and mantle connection remain interpretations to be tested, a magmatic origin for the observed sulphides has not been established, and a hydrothermal contribution or later overprinting remains possible.

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. Next Phase: Ground EM and Assays Nineteen rock chip samples (12 from Sybil and seven from Illogwa Creek) were dispatched to Bureau Veritas on 21 September 2026, together with a standard and a blank (Figure 6). At the time of the 30 September announcement, assays were expected in approximately three to four weeks. No subsequent assay results have been incorporated into this report.

Hand held GPS locations taken. As reported on 30 September, Litchfield was organising follow-up ground EM surveys over Illogwa anomaly 26 and priority Sybil conductors. The proposed surveys are designed to refine conductor geometry and test whether surface observations are related to sources at depth. Results are intended to be integrated with laboratory assays and geological mapping to inform future targeting. Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 9 of 20 Oonagalabi Project – Northern Territory Rig Secured for October Drilling Program During the quarter, Litchfield secured a Topdrill rig for the Oonagalabi Main Zone program, then scheduled to commence on 8 October 2026.³ A dozer was mobilised to prepare drill pads. The September plan comprised 11 candidate holes (OGRCP001–OGRCP011) with planned depths of 120– 200m and a total candidate program of 1,820m (Figure 7). This figure was not a committed drilling total. At that time, the Company anticipated completing eight to ten holes within Topdrill’s available drilling window, subject to geological priority, pad readiness, drilling productivity and ground conditions. Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 10 of 20 Figure 7.

Coordinates are GDA94 / MGA Zone 53. Inset shows the map extent within the full image. Traces connect planned collars and end-of-hole positions in plan projection and are not surveyed trajectories. Formation outlines do not define mineralisation limits. Hole IDs are numbered southwest to northeast along the Main Zone and do not indicate drilling order or individual hole priority. The program was designed around three principal objectives: • test extensions to known mineralisation; • improve the definition of mineralised geometry and structural controls; and Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 11 of 20 • investigate new areas within the Main Zone. The program builds on previously reported broad copper-zinc mineralisation in the Main Zone, including combined downhole intercepts of 68.26m @ 0.62% Cu, 1.44% Zn and 4.3g/t Ag from 10m in OGDD002, as well as 120m @ 0.35% Cu, 0.92% Zn and 4.1g/t Ag from 52m in OGRC029.9 Results are expected to inform the Main Zone geological model and subsequent drill targeting. Subsequent to quarter-end, the Company announced the commencement of drilling at Oonagalabi on 12 October 2026. The commencement announcement outlined a program of approximately seven to eleven holes, with the final number subject to drilling progress, ground conditions and the available campaign window. Final Phase 3 Assays Received Final assay results from the Phase 3 drilling campaign were returned in late June 2026 and reported during the quarter. The best intercept from diamond hole OGDD003, which targeted the Oonagalabi Magnetic Finger, was 5.3m @ 0.64% Cu, 0.67% Zn and 2.2g/t Ag from 49.5m. All widths are downhole; true widths are not known. Magnetotelluric and Gravity Survey During the quarter, the Company undertook the combined magnetotelluric (MT) and gravity survey program across its western Harts Range tenements near Oonagalabi, contracted to Planetary Geophysics and supported by up to AUD$100,000 in Northern Territory Geological Survey co-funding under Round 19 of the Geophysics and Drilling Collaborations program. The survey is designed to investigate a conductivity anomaly interpreted at approximately 2.5km depth and improve the Company’s regional targeting framework (Figure 8). No survey results are reported in this quarterly. 9 LMS ASX Announcement, Oonagalabi Drilling Strengthens Geological and Targeting Models, dated 3 June 2026.

Finalised MT survey lines (MT 1 and MT 2) over modelled conductivity, 2,500m slice (relative,polarity inverted so warm tones indicate stronger conductors). GDA94 MGA Zone 53 (EPSG:28353). Silver Valley Project, Northern Territory Initial IP Survey Completed An initial IP survey was completed at Silver Valley (EL32241) between 8 and 17 July 2026, with three lines totalling 5.1 line-km acquired by Australian Geophysical Services and independently processed by Mitre Geophysics.4 The survey did not define a discrete, high-priority drill target within the area surveyed, and the chargeability responses recorded were weak in absolute terms (Figures 9 and 10). However, the northern line identified a chargeability response immediately west of the known Silver Valley workings, with modelling suggesting potential depth extent towards the west, and elevated chargeability was also present towards the western ends of the two southern lines. Deeper low-resistivity zones on the southern lines may represent geological structure, although they may also be inversion artefacts. Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 13 of 20 Figure 9. Three-dimensional perspective view (looking north) of the 2D inverted chargeability sections for lines 21100N, 20700N and 20500N. Elevated chargeability is concentrated towards the western ends of all three lines, immediately west of the Silver Valley 2 workings. Red dots are known mineral occurrences and pink dots are mapped old workings. Figure 10. Three-dimensional perspective view (looking north) of the 2D inverted resistivity sections. Deeper low-resistivity zones on the southern lines 20700N and 20500N sit beneath and to the west of the elevated chargeability and may be mapping the interpreted western structural corridor. Red dots are known mineral occurrences and pink dots are mapped old workings. The relatively modest IP response is consistent with the style of mineralisation observed at surface. Galena, which hosts much of the lead and associated silver, typically produces a weaker chargeability response than other sulphides such as pyrite. When integrated with concurrent field mapping, the results suggest the original survey design may not have fully tested the most prospective structural zones. The Company therefore concluded the mobilisation after three of the five planned lines, rather than continue spending against a survey footprint that may not be optimally positioned. New High-Grade Rock Chip Results Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 14 of 20 Five new rock chip samples collected from dumps adjacent to historical shafts and workings at Silver Valley returned the following results, announced on 10 August 2026:⁴ • SV2_06: 470g/t Ag, 0.08g/t Au, 19.2% Cu and 23.2% Pb; and • SV2_08: 342g/t Ag, 0.06g/t Au, 16.1% Cu and 36.8% Pb. These results complement previously reported high-grade rock chip results from elsewhere at Silver Valley, including 378g/t Ag, 0.91g/t Au, 5.04% Cu and 44.9% Pb (SV2-04).10 Rock chip samples are selective and are not representative of grade or continuity. Next Phase: Targeted Mapping and Revised IP As outlined in the August announcement, the Company intends to undertake targeted mapping and structural investigation west of the original IP footprint and integrate those observations with chargeability and resistivity models to optimise the remaining survey lines. Field resources were proposed to be redeployed following the Harts Range MT and gravity work. No additional IP results are reported for the quarter. Harts Range Corridor – BHP Xplor Program The BHP Xplor-backed research reported on 18 June 2026 reframed the Harts Range from a collection of copper and nickel deposits and prospects into a belt-scale copper-nickel mineral system with the potential to host significant discoveries. As reported on 30 September 2026, 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 (Figure 11). Such a structure could have helped channel mafic magma into the crust, making the corridor an attractive setting to investigate for orthomagmatic copper-nickel systems. The depth extent and mantle connection remain interpretations to be tested. 10 LMS ASX Announcement, Diamond and RC Drill Program Completed at Oonagalabi & Silver Valley Delivers High-Grade Silver-Lead-Copper Results, dated 23 April 2026.

On 18 September 2026, the Company released its Investor Presentation ahead of the BHP Xplor Showcase Investor Day. The MT and gravity survey program undertaken during the quarter was designed to investigate a conductivity anomaly interpreted at approximately 2.5km depth across the Company's western Harts Range tenements. LucyCreek Project No material exploration activities were undertaken at the Lucy Creek Project during the June 2026 quarter. Litchfield Minerals Limited · www.litchfieldminerals.com.au Page 16 of 20 Exploration Summary During the September 2026 quarter, Litchfield progressed field validation of exploration targets across its expanded Harts Range position. The grant of EL34245 allowed the Company to undertake field reconnaissance at Sybil and Illogwa Creek, where copper-bearing minerals were visually identified at Sybil and sulphide-bearing mafic rocks were identified at Illogwa Creek. These observations informed the priorities for planned follow-up ground EM surveys. At Silver Valley, the Company paused the initial IP survey after three lines to integrate the results with field mapping and reconsider the positioning of the remaining survey lines. The Company entered the December quarter with planned ground EM follow-up at Sybil and Illogwa Creek, laboratory results awaited from September sampling, a revised IP strategy at Silver Valley and an October drilling program at the Oonagalabi Main Zone. Drilling at Oonagalabi subsequently commenced, as announced on 12 October 2026.
