Announcement PDF ASX Announcement 9 February 2026 Exploration Update – Resumption of Field Activities in Cameroon Highlights • Multiple work programs and studies underway to unlock the rutile and REE potential of the Central Rutile Project. • Deep hand-auger drilling continues at the Bounde and Nganda licences, targeting the historically mapped 70 × 15 km BRGM high-grade rutile corridor. • Systematic soil-sampling underway at the newly acquired Yaoundé West licences. • Primary pXRF completed on 608 soil samples collected across the Central Rutile Project, data currently being assessed to interpret initial Ti and REE anomalies across the zone. • Airborne radiometric dataset acquired over the Central Rutile Project, interpretation underway. • Integration of pXRF results with radiometrics to delineate priority monazite/REE targets. • Commissioning of Tusker’s Yaoundé heavy-mineral sands laboratory imminent, with steady state processing expected late Q1 / early Q2. • Desktop remote-sensing targeting work underway to delineate priority targets for Q2 drill testing at the Douala Basin HMS project. • Engage with this announcement at the Tusker Minerals Investor Hub. Tusker Minerals Ltd (ASX: TSK, “Tusker” or “the Company”) is pleased to announce the resumption of field activities across its Cameroon exploration portfolio, with multiple programs now underway targeting rutile and monazite-hosted rare earth element (REE) mineralisation. Deep hand-auger drilling is progressing at the Bounde and Nganda licences, while systematic soil sampling has commenced at the newly acquired Yaoundé West licences. Primary pXRF results of the recently completed soil campaign across the Central Rutile Project are currently being assessed in order to provide preliminary insight into the central license package. The full geochemical analysis is underway and will be integrated with the radiometrics to delineate anomalous titanium and monazite/REE targets for follow-up drill testing. Desktop studies have also commenced at the Douala Basin HMS Project, where targeted auger drilling is scheduled for Q2. Commissioning of Tusker’s new heavy mineral sands laboratory in Yaoundé is imminent and will provide significant in-country analytical capacity to support the Company’s expanding exploration programs. Hand-Auger Drilling Across High-Priority Targets The ongoing hand-auger drilling program at the Bounde and Nganda licences is progressing strongly, with all holes completed to date reaching planned depths of 12–16 metres. Drilling efficiency has been supported by Tusker’s heavy-duty, tungsten-carbide reinforced equipment and experienced in-house technical team. The program is systematically evaluating the historically defined 70 × 15 km BRGM-mapped high- grade residual rutile corridor, representing the first modern, methodical drill testing of this highly prospective mineralised trend.

Systematic Soil Sampling Campaign Underway at Yaoundé West A planned, systematic soil sampling campaign has commenced across the Yaoundé West licence package, aimed at establishing a robust geochemical dataset for the project area. Samples will be analysed using pXRF at Tusker’s Yaoundé laboratory, with the results used to identify anomalous titanium and REE target zones for focused follow-up hand-auger drilling.

Heavy Mineral Sands Laboratory Commissioning Commissioning of Tusker’s in-country mineral sands laboratory in Yaoundé is now imminent. Once fully operational, the facility will provide: • Rapid turnaround of sample preparation and mineral separation • Support for expanding soil and auger drilling programs • Greater operational efficiency and cost control The Company expects the laboratory to reach steady-state processing capacity in late Q1 to early Q2, supporting a substantial increase in exploration activity through 2026. pXRF Analysis of Soil Samples and Airborne Radiometric Data Acquired Primary pXRF analysis of the 608 soil samples previously collected across the Central Rutile Project has now been completed, and the dataset is currently being assessed. These results will form part of the initial interpretation of the exploration potential within the central package. The initial geochemical data will also be integrated with recently acquired airborne radiometric data to identify and define preliminary REE and monazite target zones. The full geochemical analysis of the soil samples are underway and will be used to delineate follow-up drill targets Desktop Remote-Sensing Targeting Underway at the Douala Basin HMS Project Desktop remote-sensing studies are underway at the Douala Basin HMS Project to refine priority targets ahead of planned Q2 drill testing. The work is focused on identifying prospective geomorphological and palaeo-shoreline features associated with heavy mineral sands accumulation, with results to guide upcoming field programs. Chief Executive Officer, Cliff Fitzhenry, commented: “The resumption of field activities in Cameroon marks the beginning of a very active and exciting exploration phase for Tusker, with multiple programs now advancing across our portfolio. The completion of the primary pXRF analysis across our Central Rutile Project soils, combined with newly acquired radiometric data, provides a powerful foundation for identifying and ranking priority targets prospective for both titanium as well as monazite-hosted rare earth mineralisation. With auger drilling commencing and multiple regional programs already underway, we are systematically building the geological understanding required to unlock the scale potential of our portfolio. The imminent commissioning of our Yaoundé laboratory further strengthens our operational capability, allowing faster turnaround of results and supporting a more efficient exploration pipeline. We look forward to delivering consistent exploration newsflow as these programs progress.” Figure 3: Map of Cameroon showing Tusker Mineral’s Central Rutile Project in green, and the Douala Basin Project in blue, encompassing +11,000km2 of highly prospective tenure. -ENDS- This announcement has been authorised by the Board of Tusker Minerals.
