Announcement PDF ASX ANNOUNCEMENT Watheroo IP Survey Further Defines Cu-Ni-PGE Drill Targets Highlights: Dalaroo Metals Ltd (ASX: DAL) (“Dalaroo” or the “Company”) is pleased to announce the completion and interpretation of a ground Dipole-Dipole Induced Polarisation (DDIP) survey at the Watheroo Cu-Ni-PGE prospect, forming part of the Company’s 100%-owned Watheroo Project in the mid-north Wheatbelt of Western Australia (Figure 1). The survey, undertaken by Fender Geophysics, was designed to investigate the subsurface beneath the recently expanded Cu-Ni-PGE soil geochemical footprint and to identify potential zones of disseminated sulphide mineralisation associated with the interpreted buried mafic-ultramafic intrusive system. The results have successfully defined a series of coincident chargeability, resistivity and magnetic features that correlate with the Company’s existing geological and geochemical datasets, providing several priority targets for a planned deep RC drilling program.

Reported background values reach 12.0 mV/V. • Deep-Seated Structural Controls: Steeply dipping, high-contrast resistivity boundaries persist across all three IP lines and coincide with a broad Cu-Ni-S-PGE geochemical halo and elevated chargeability. • Coincident Exploration Responses: Modelled chargeability and resistivity features coincide with a magnetic break and areas of elevated Cu-Ni-PGE and sulphur soil geochemistry, supporting a potential buried mafic-ultramafic intrusion. • Integrated 3D Model: Three-dimensional modelling defines the spatial relationship between the chargeability, resistivity and sensitivity responses, which remain open to the south and at depth. Model sensitivity decreases with depth, requiring greater caution when interpreting deeper features. • Priority Drill Targets: Integrated geophysical, geological and geochemical datasets have defined priority targets for potential RC drilling. 2 dalaroometals.com.au | ASX: DAL Dalaroo Metals CEO – John Morgan commented: “The Watheroo IP survey has materially strengthened our exploration model and, importantly, moved the project towards drill testing. “We now have a compelling convergence of geological, geochemical and geophysical evidence across a very large intrusive system. The combination of olivine gabbro and serpentinite, a 7-kilometre by 3-kilometre magnetic footprint, anomalous Cu-Ni-PGE and sulphur geochemistry and now a strong, steeply dipping IP response provides multiple independent vectors towards a potential magmatic sulphide system. The scale and consistency of the responses across all three survey lines are highly encouraging, with the strongest modelled chargeability response reaching approximately 18 mV/V in the 2D inversion of Line 6641700N. Our next step is to test the priority targets at depth through drilling. Watheroo represents an exciting greenfields opportunity in Western Australia, and the emerging geological characteristics provide an increasingly compelling comparison with the style of magmatic systems that have delivered significant Ni-Cu-PGE discoveries elsewhere in the Julimar region.” Figure 1: UAV magnetics acquired at 50 m flight altitude, overlain by Cu soil geochemistry and IP survey lines, showing the spatial relationship between magnetic anomalies, surface Cu anomalism, and IP survey coverage. IP Survey Defines Large Subsurface Chargeability Response The DDIP survey comprised approximately 6,300 m across three east–west profiles, comprising 83 stations at nominal 100 m station spacing, using a 100 m dipole length and lines approximately 300 m apart. The data were processed and inverted in two and three dimensions by Fender Geophysics using RES2DINV and RES3DINV version 2026.1. 3 dalaroometals.com.au | ASX: DAL The 2D inversion of Line 6641700N identified a steeply dipping chargeability response reaching approximately 18 mV/V. Observed survey data contain chargeability values of up to 19.4 mV/V. The 10 mV/V surface is an interpretive contour used to illustrate the geometry of the modelled response and is not a threshold separating anomalous chargeability from background, which Fender reported as reaching 12.0 mV/V. The integrated 3D inversion provides a broader representation of the spatial relationship between the chargeability, resistivity and model sensitivity responses across the three lines. No specific sensitivity threshold was applied. Sensitivity decreases with depth, and deeper modelled features should therefore be interpreted with greater caution. The final 2D resistivity RMS misfits were 26.78% for Line 6641700N, 8.72% for Line 6642000N and 8.52% for Line 6642300N. The corresponding IP RMS misfits were 2.14 mV/V, 1.99 mV/V and 1.22 mV/V respectively. The higher resistivity misfit on Line 6641700N introduces additional uncertainty into the detailed geometry of the resistivity response on that line. The survey contractor has reported that data quality was reasonably good throughout the survey, but that conductive soils in several places reduced signal amplitudes at depth, resulting in noisier data and diminished repeatability of the decay curves (mean primary voltage at n = 10 of 2.3 mV). Low signal levels in those areas may influence the inversion and overstate the modelled amplitude of the chargeability response, and the quoted chargeability values should be considered in that context. The scale and geometry of the response provide a substantial new drill target beneath the existing surface geochemical footprint. Importantly, a prominent low-resistivity (conductive) unit identified within the inversion model is not closed off by the current survey coverage to the south or at depth, indicating that the geophysical system may extend beyond the current survey coverage. Figure 2: Three-dimensional IP inversion model showing the spatial extent of the chargeability anomaly within the survey area. 4 dalaroometals.com.au | ASX: DAL Figure 3: 3D inversion model highlighting a strong chargeability anomaly that is not closed off by the current survey coverage to the south or at depth, providing priority targets for follow-up drilling. Chargeability Response Coincides with Magnetic Break The 3D inversion identifies a pronounced high-resistivity zone on the western side of the survey area, with medium-to-high chargeability concentrated along the boundary between the high- and lower-resistivity domains. This boundary corresponds closely with a distinct break in the airborne magnetic response (Figure 1). The Company considers this spatial relationship significant, as it provides a potential geological contact between contrasting rock units and supports the interpretation that the high-resistivity zone may represent a buried mafic-ultramafic intrusive body. Application of a tilt-derivative filter to the reduced-to-pole magnetic data further sharpens the magnetic break and assists in defining the interpreted intrusive contact. The concentration of elevated chargeability along this boundary is considered particularly prospective because magmaticNi-Cu-PGE sulphideaccumulationscanoccur atorproximal to contacts and structural margins within mafic-ultramafic intrusive systems. The coincidence of the chargeability response with the interpreted intrusive contact and independent geochemical and magnetic anomalies provides a compelling basis for drill testing. Induced polarisation responses are not diagnostic of sulphide mineralisation and may also be caused by graphite, clay-rich lithologies, weathering products or saline groundwater. The anomalies therefore require drill testing to determine their geological source. 5 dalaroometals.com.au | ASX: DAL Figure 4: Two-dimensional inversion of IP Line 3 1700N showing a chargeability response extending for approximately 1 km using the 10 mV/V interpretive contour. The modelled response reaches approximately 18 mV/V. Fender reported background chargeability values of up to 12.0 mV/V. Significance of Deep-Seated Resistivity Boundaries A significant feature of the IP survey is the presence of sharp, steeply dipping, high-contrast resistivity boundaries consistently identified across all three survey lines (Figures 5 to 8). Their continuity and depth extent suggest a coherent bedrock feature, potentially representing a major lithological contact, intrusive margin or structurally controlled alteration zone. Importantly, these boundaries broadly follow a linear geochemical halo characterised by elevated Cu-Ni-S- PGE values at surface. The spatial association between the deep resistivity architecture, elevated chargeability and this multi-element geochemical trend defines a coherent exploration target requiring drill testing. The coincidence of these features raises the possibility that the resistivity boundaries define potential structural or lithological controls on sulphide-bearing geology, potentially associated with the margins or internal architecture of a buried mafic intrusive body. The broad Cu-Ni-S-PGE anomalism may represent the surface expression of a sulphide-bearing geological system, although drilling is required to determine the source and significance of the geophysical and geochemical responses. While resistivity contrasts alone are not diagnostic of mineralisation, the coincidence and continuity of the resistivity, IP chargeability and Cu-Ni-S-PGE geochemical responses across the three survey lines materially enhance the exploration potential of the target and warrant priority consideration for follow-up drilling. 6 dalaroometals.com.au | ASX: DAL Figure 5: 3D inversion resistivity model highlighting two distinct, sharp and steeply dipping deep-seated resistivity contacts (white dashed lines), which define priority targets for follow-up drill testing.

Stage 1 soil sampling defined a coherent Cu-Ni response extending approximately 2 km south of the historical sampling area, with peak values of 284 ppm Cu and 176 ppm Ni, together with values of up to 10 ppb Pt, 10 ppb Pd and 10 ppb Au. The multi-element geochemistry is spatially associated with the broader 7 km × 3 km magnetic feature interpreted to represent the Watheroo intrusive system. The new IP results strengthen this geological model, with the principal chargeability responses occurring in the vicinity of the interpreted magnetic break and zones where Cu, Ni, Co and S soil geochemistry are elevated. The combined response of: • high chargeability; • contrasting resistivity domains; • a pronounced magnetic break; • elevated Cu-Ni-PGE geochemistry; • elevated sulphur; • mapped olivine gabbro and serpentinite. 8 dalaroometals.com.au | ASX: DAL Watheroo's Julimar-Style Exploration Model Strengthened Watheroo remains a compelling greenfields magmatic Cu-Ni-PGE exploration opportunity within the Western Australian Wheatbelt. Recent geological mapping identified extensive olivine gabbro and scattered serpentinite, confirming the presence of primitive mafic-ultramafic rocks consistent with a prospective magmatic plumbing system. The interpreted Watheroo chonolith is characterised by a large magnetic footprint approximately 7 km long by 3 km wide, with surface Cu-Ni-PGE geochemistry distributed across parts of the system. This geological setting provides an exploration model broadly analogous to the magmatic intrusive systems being explored elsewhere within the Julimar Province, where mafic-ultramafic intrusions, structural architecture, sulphur-rich country rocks and magmatic sulphide accumulation combine to form Ni-Cu-PGE sulphide systems. At Watheroo, field observations of trace to minor disseminated sulphides within mapped mafic-ultramafic rocks, combined with the coincident geochemical, magnetic and IP responses, support continued testing of the Company's Julimar-style magmatic Ni-Cu-PGE exploration model. Drill Program to Test Priority IP Targets The integration of the new 3D IP inversion with airborne magnetics, soil geochemistry and geological mapping has enabled Dalaroo to refine the priority areas for drill testing. The Company is planning a deep RC drilling program with holes of approximately 300 metres depth to test the principal chargeability responses and their relationship to the interpreted mafic-ultramafic intrusion. Priority drill targets will focus on the strongest chargeability responses, particularly where they coincide with: 1. the interpreted magnetic and resistivity boundary; 2. elevated Cu-Ni-PGE and sulphur geochemistry; 3. interpreted intrusive contacts; and 4. extensions of the chargeability response at depth and along strike. The planned drilling is designed to provide the first systematic test of the deeper architecture beneath the extensive Watheroo surface geochemical and geophysical footprint. Project Overview and Regional Setting The Watheroo Chonolith prospect is a high-priority exploration target situated within Dalaroo’s 100%-owned Watheroo Project, located in the mid-north wheatbelt of Western Australia (Figure 9). The project is strategically positioned along the western margin of the Archaean Yilgarn Craton, bounded by the regional-scale Darling Fault system. This highly disrupted structural corridor is recognised as a major crustal-scale plumbing network capable of channelling deep-seated, mantle-derived magmas into the upper crust. Regionally, the Watheroo Project sits within the broader western margin of the Yilgarn Craton that hosts Chalice Mining Limited's (ASX: CHN) Julimar Ni-Cu-PGE deposit further to the south. Historically overlooked due to extensive agricultural cover, this western craton margin is now established as an emerging province for large- scale magmatic sulphide systems. Dalaroo's tenure over this fertile structural zone provides the Company with 9 dalaroometals.com.au | ASX: DAL an early-mover position from which to deploy modern geophysics and targeted geochemistry across previously untested undercover targets. Figure 9: Watheroo project location map. The comparison with Julimar–Gonneville is regional and conceptual only. Watheroo remains an early-stage exploration project, and no assurance can be given that it will host mineralisation of a similar style, scale, grade or continuity. Management Commentary Dalaroo Metals Exploration Manager – Trystan Hughes commented: “The IP results provide an important new layer of information beneath the extensive surface geochemical response at Watheroo. The strongest chargeability is spatially associated with a distinct, high-contrast resistivity boundary that coincides with a major magnetic break, highlighting a potentially significant lithological or structural contact within the buried mafic-ultramafic intrusive system. 10 dalaroometals.com.au | ASX: DAL Importantly, sharp, steeply dipping resistivity boundaries persist across all three IP lines, demonstrating continuity of the underlying bedrock architecture at depth. These features broadly follow a linear geochemical halo characterised by elevated Cu-Ni-Co-S-PGE values, while the presence of olivine gabbro and serpentinite at surface provides additional geological support for a mafic-ultramafic system. The coincidence of elevated chargeability with this geochemical and geological footprint defines a potential sulphide-bearing target associated with the Watheroo magmatic system that requires drill testing. The 3D inversion indicates that the conductive and chargeable system remains open to the south and at depth, providing significant scope to extend the target beyond the current IP coverage. The priority is now to test the strongest coincident IP, magnetic and geochemical responses with deep RC drilling and determine whether the geophysical anomalies represent sulphide-bearing portions of the Watheroo magmatic system.” Next Steps To systematically advance the Watheroo prospect and refine priority areas for further evaluation, Dalaroo has planned a phased exploration program: • Expanded Geochemistry: Complete the remaining approximately 360 planned soil samples, supported by regional stream-sediment sampling, targeted rock-chip sampling and ongoing geological mapping. This work will further define the lateral extent and internal geochemical zonation of the broader target. • Maiden Drill Planning: Use the integrated datasets to finalise proposed drill targets and orientations. The planned program would test priority positions within the modelled chargeability responses and along interpreted resistivity boundaries. • Downhole EM Surveys: If drilling proceeds, consider downhole electromagnetic surveying to identify potential off-hole conductors beyond theimmediate drill holes and generate additional targets for follow- up exploration.

These examples should not be taken as limiting the broad meaning of sampling Include reference to measures taken to ensure sample representativity 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. The current Stage 1 program comprised 106 soil samples collected predominantly on a nominal 200 m × 100 m grid. A limited number of isolated samples were collected at nominal 100 m station spacing along lines approximately 400 m apart where required to connect the current sampling with historical sampling lines. Planned follow-up infill sampling will use a nominal 100 m × 50 m grid across selected priority areas. No results from the planned infill sampling are reported in this announcement. Current Stage 1 samples were collected using a hand auger from approximately 10–50 cm depth, targeting material below the organic surface horizon. The ground induced polarisation survey reported in this announcement was acquired by Fender Geophysics using a dipole-dipole induced polarisation (DDIP) array. The survey was conducted between 7 and 16 August 2026. Three east–west survey lines (bearing 090°) totalling approximately 6,300 m were read, comprising 83 stations at nominal 100 m station spacing with lines approximately 300 m apart. Individual line lengths were 2,200 m (1700N), 1,800 m (2000N) and 2,300 m (2300N); Lines 1700N and 2300N were extended eastwards by 400 m and 500 m respectively during the survey to better define anomalies at the eastern end of the originally planned lines. The three lines are identified as 6641700N, 6642000N and 6642300N (MGA Zone 50 northings), and are referred to in this announcement as Lines 3, 2 and 1 respectively. Acquisition parameters were: dipole-dipole array with 100 m dipole spacing; n-separations to a maximum of n=16, signal dependent; time- domain acquisition on a 2 second cycle (0.125 Hz); transmitter Instrumentation GDD Tx 4 (5 kVA), with output current in the range 0.7 A to 7.0 A; receiver Instrumentation GDD Rx-32 16-channel; and chargeability measured over the time window 590–1,540 ms. A minimum of three readings was taken at each station to verify repeatability, with 13 dalaroometals.com.au | ASX: DAL Sub-section JORC Code Explanation Disclosure between 2 and 9-fold stacking per reading and visual inspection of individual decay stacks. Chargeability and resistivity are modelled physical properties of the bedrock. They are not a measurement of metal content and do not of themselves demonstrate the presence of mineralisation.
