Announcement PDF Ground Floor, 8 St Georges Terrace, Perth WA 6000 +61 8 9486 4036 tuskerminerals.com ABN: 91 663 592 318 ASX Announcement 30 September 2026 Mzimba Phase 1 Sampling Results Updated geological interpretation following regional soils and shallow pit testing Mzimba Exploration Highlights • A systematic Phase 1 exploration programme has been completed at Mzimba, progressing from historical data review and XRD mineralogical verification to regional soil sampling and shallow pit testing. • Historical TiO₂ anomalies were confirmed to contain rutile by XRD. • Follow-up work comprised 149 regional soil samples and 33 pit-channel samples, with magnetic and non-magnetic heavy-mineral fractions analysed by XRF. • The soils define titanium enrichment over a wider area than the original XRD points, including two broad surface rutile-equivalent responses of approximately 16×2km and 13×2km, with peak calculated rutile-equivalent values of 0.69-0.71% and 0.61-0.70%, respectively. • Magnetic titanium exceeds calculated rutile-equivalent in 112 of 149 soil samples. The working interpretation is now an ilmenite-dominant residual titanium system with localised rutile, rather than a high-grade natural rutile occurrence with minimal ilmenite. • Shallow pits (generally to 5-6m) did not demonstrate high-grade rutile grade persistence with depth. • The new data refines the Company’s understanding of the mineralisation style at Mzimba. The project warrants a targeting reassessment before any next-phase work is designed. Near-term capital and technical priority remains focused on Cameroon. • Engage with this announcement at the Tusker Minerals Investor Hub Chief Executive Officer, Cliff Fitzhenry, commented: "Phase 1 was designed to test whether the early XRD rutile confirmations represented a continuous, high-grade residual rutile system. The soils show titanium enrichment over a wider footprint than those first points, with rutile present but subordinate to magnetic titanium across most of the grid. Pit channels did not lift rutile grade with depth. That is a different geological picture from the one implied by the initial mineralogical work alone. We will use the new assemblage and spatial data to reassess the model and targeting before committing to a further programme at Mzimba. In the meantime our field and capital focus remains on Cameroon." Ground Floor, 8 St Georges Terrace, Perth WA 6000 +61 8 9486 4036 tuskerminerals.com ABN: 91 663 592 318 Updated Interpretation of Mzimba Results The Company’s initial XRD work confirmed the presence of rutile in selected anomalous soil samples. At that stage the extent, continuity and titanium-mineral assemblage across the Mzimba licences were not known. Subsequent regional soils, magnetic / non-magnetic fraction analysis and shallow pit testing were undertaken to test whether the initial rutile occurrences represented a broader, continuous rutile- dominant system. The follow-up programme confirmed that rutile is present at Mzimba, with several localised surface anomalies. Those anomalies sit inside a more extensive titanium response that is predominantly magnetic (ilmenite-equivalent). The current interpretation is a residual / eluvial heavy-mineral setting in weathered Irumide Belt gneiss, in which tropical weathering has concentrated titanium minerals in the near-surface profile. Within that setting, ilmenite is the dominant titanium phase at the scale of the wide-spaced 2km soil grid, with rutile occurring as localised surface lenses. Shallow pit testing of selected anomalies did not demonstrate the grade persistence required to move immediately to a drill programme. That conclusion is specific to the rutile-dominant discovery thesis tested in Phase 1. Titanium enrichment has nonetheless been mapped across a wider area than the initial XRD points. What the soil results show Regional soils were collected on an approximate 2km × 2km grid from residual regolith. Heavy-mineral concentrates were magnetically split and both fractions analysed by XRF at the Geological Survey Department, Zomba. Calculated rutile-equivalent is localised. Two of the more coherent surface responses are on the order of 16×2km and 13×2km, with peaks of 0.69-0.71% and 0.61-0.70% rutile-equivalent (Figure 1; Table 3). Mean soil rutile-equivalent is approximately 0.08%, with a large population of samples at or near detection. Calculated ilmenite-equivalent is more widespread and reaches materially higher values (soil mean approximately 0.55%, maximum 3.37%). Magnetic titanium exceeds rutile-equivalent in 112 of 149 samples. That contrast is the principal reason the geological model has been updated. What the pits show Thirty-three 1m channel samples were collected from hand-dug pits sited proximal to historical TiO₂ anomalies, generally to 5–6m depth. Calculated rutile-equivalent in pit channels peaks at 0.10% (PIT03, 0-1m - Table 2) and is commonly at or below 0.08% in the upper metres, falling further or remaining negligible with depth in several pits. Magnetic titanium is again the stronger signal in the majority of intervals assayed. The pits were a test of near-surface persistence and not used as a substitute for drilling. They do not support an immediate rutile-focused drill programme on the Phase 1 anomalies.

The rutile response is localised, whereas the ilmenite-equivalent response is more widespread and reaches materially higher values. Figure 2: Regional soil sampling results shown together with the earlier XRD-rutile occurrences. The initial rutile occurrences are confirmed and geologically consistent with the regional results, but do not define a continuous licence-scale rutile system. Ground Floor, 8 St Georges Terrace, Perth WA 6000 +61 8 9486 4036 tuskerminerals.com ABN: 91 663 592 318 Next Steps The Company will reassess the Mzimba geological model and targeting using the Phase 1 assemblage and spatial dataset before any next-phase work is designed. That reassessment will consider whether any further work is justified, and if so on what commodity and at what scale including whether rutile remains the primary target or whether titanium more broadly should be treated as the exploration thesis. No drilling is planned at Mzimba pending that reassessment, with near-term capital and technical resources directed to the Company’s Cameroon projects. A decision on the three Mzimba exploration licences (EL0784, EL0732 and EL0783) will follow that reassessment and the Company’s broader portfolio priorities. -ENDS- This announcement has been authorised by the Board of Tusker Minerals.

Ground Floor, 8 St Georges Terrace, Perth WA 6000 +61 8 9486 4036 tuskerminerals.com ABN: 91 663 592 318 Section 1 Sampling Techniques and Data Criteria Explanation Comment 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. Pit Channel sampling • Channel samples were collected from pits excavated proximal to 6 historical TiO2 anomalous soil samples • Pits were hand dug. • Samples were collected at consistent 1 m intervals • Industry-standard practice was used in the processing of samples for assay. Soil sampling • Soil samples were collected using a shovel. • Sampling targeted the residual regolith horizon to best represent geochemical signatures. • Organic topsoil was first removed, and samples were collected from 50–70 cm depth below this layer. Each sample weighed approximately 4-6 kg. • Sampling sites were carefully selected to avoid disturbed areas, including zones of active erosion and any man- made features. • Industry-standard practice was used in the processing of samples for assay • 145 soil samples and 35 pit samples were collected whilst 2 were discarded. 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 was conducted Drill sample recovery Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample 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. Soil sampling • Organic topsoil was first removed, and samples were collected from 50–70 cm depth below this layer. Each sample weighed approximately 4–6 kg. • GPS coordinates recorded at each site using handheld GPS (±5 m accuracy). Channel sampling • Sample information was recorded at the time of sampling • GPS coordinates recorded at each site using handheld GPS (±5 m accuracy). Ground Floor, 8 St Georges Terrace, Perth WA 6000 +61 8 9486 4036 tuskerminerals.com ABN: 91 663 592 318 Logging Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the relevant intersections logged. • Sample information was recorded at the time of sampling • GPS coordinates recorded at each site using handheld GPS (±5 m accuracy). Sub-sampling 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. Soil Sampling: • A sample weighing approximately 4-6 kg was collected from each site, targeting residual material • Organic material was removed prior to sampling to avoid contamination. • Samples were bagged and tagged on site with unique sample IDs. • Samples were split into a 1kg representative sample using a rifle splitter • The samples were dried for an accurate primary dry weight • Samples were panned for HM concentrate • HM concentrate was sent to GSD of Malawi in Zomba for oven drying, magnetic separation and XRF analysis Pit Channel sampling • Channel samples were collected from pits excavated proximal to 6 historical TiO2 anomalous soil samples • Pits were hand dug • Samples collected at consistent 1m intervals • Organic material was removed prior to sampling to avoid contamination. • Samples were bagged and tagged on site with unique sample IDs. • Samples were split into 1kg representative samples using a rifle splitter • The samples were dried for an accurate primary dry weight • Sample were panned for HM concentrate • HM concentrate was sent to GSD of Malawi in Zomba for oven drying, magnetic separation and XRF analysis Ground Floor, 8 St Georges Terrace, Perth WA 6000 +61 8 9486 4036 tuskerminerals.com ABN: 91 663 592 318 Quality of assay data and laboratory tests The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. • Sample analysis was performed by the GSD of Malawi. • HM conc were oven dried for 12hours • Magnetic separation was performed on HM conc and a magnetic and non- magnetic fraction was produced • Magnetic and non-magnetic fraction were analysed using XRF 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 third-party verification recorded. • No twinned boreholes were drilled. • No adjustments to data have been recorded.
