TIDMBSE AIM and Media Release 30 October 2023 Base Resources Limited Kwale East - Exploration update Base Resources Limited (ASX & AIM: BSE) (Base Resources or the Company) advises that, following conclusion of a limited phase 2 air core drilling program (Phase 2) at its Kwale East exploration project (Kwale East) in Kwale County, Kenya, exploration activities at Kwale East have been discontinued. Explorations activities undertaken Kwale East is located within ProspectingLicence2018/0119 and is the eastern expression of a large, mineralised Plio-Pleistocene dune system also covering the Kwale Central, South and North Dunes and the Bumamani deposit - refer to Figure 1. Kwale East was considered a near-term mine life extension opportunity due to its close proximity to Kwale Operations' infrastructure. An initial phase 1 scout auger drilling program (Phase 1) completed over 2022 and 2023 identified three targets - Magaoni, Masindini and Zigira - for follow -up aircore drilling as part of Phase 2. Refer to Figure 2 for the location of these target areas and the Phase 1 drill holes, and the Company's announcement of 3 July 2023, titled "Kwale East exploration drilling update" (the July Announcement), for further details in relation to Phase 1. As was noted in the July Announcement, land access was a particular challenge in the more prospective areas of Magaoni and Zigira during Phase 1, with access to approximately 35% of those target areas unable to be obtained. With community engagement trending positively and optimism over the Company's ability to secure the necessary landholder consents, the Phase 2 program was commenced. The priorities for Phase 2 were to: · drill the remaining 35% of Magaoni and Zigira; · complete infill drilling to achieve 100m north by 50m east spacing for all three targets for resource estimate purposes; and · twin Phase 1 drill holes with average HM grades of greater than 1% to enable better sample quality and allow drilling through to basement, as well as confirm mineralisation. Despite securing some additional landholder consents, the Company was ultimately unable to secure full access to the more prospective areas in Magaoni and Zigira, largely limiting the program undertaken for Phase 2 to twinning some of the Phase 1 holes. In total for Phase2, 65 holes for 1,054.5m were completed in the Magaoni and Zigira target area, resulting in 703 samples - refer to Figure 2 for the location of these holes. While the Phase 2 assay results confirmed the existence of the mineralisation identified from the Phase 1 auger program, the Company has decided to discontinue exploration activities at Kwale East. This decision followed an evaluation of the likely mineralisation for the three targets using the results from both Phase1 and Phase2 drill programs and applying optimistic assumptions on the continuity of mineralisation in the Magaoni and Zigira target areas that were not able to be drilled. Even on these optimistic assumptions, the evaluation concluded that there is unlikely to be sufficient volume or heavy mineral grade to support an economically viable mining development. For further details about the evaluation undertaken, refer to the Company's announcement titled "Kwale Operations to complete mining at end of 2024", also released today. For further details about the results from Phase 2 drilling, refer to the Appendices below, comprising a table of assay results for all drill holes having an average grade equal to or greater than 1% HM (refer to Appendix 1) and the information provided for the purposes of Sections 1 and 2 of Table 1 of the JORC Code (refer to Appendix 2). For completeness, Appendix 1 also discloses further assay results from Phase 1 received subsequent to the cut-off for the July Announcement and having an average grade equal to or greater than 1% HM, and Appendix 2 also contains information provided for the purposes of Sections 1 and 2 of Table 1 of the JORC Code in respect for those assay results. A glossary of key terms used in this announcement is contained below. Competent Person's Statement The information in this announcement that relates to Kwale East exploration results is based on, and fairly represents, information and supporting documentation prepared by Mr. Edwin Owino. Mr. Owino is a member of the Australian Institute of Geoscientists. Mr.Owino is employed by Base Resources' wholly-owned subsidiary, Base Titanium. Mr. Owino holds equity securities in Base Resources and is entitled to participate in Base Resources' long-term incentive plan and receive equity securities under that plan. Details about that plan are included in Base Resources' 2023 Annual Report. Mr. Owino has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the JORC Code and as a Qualified Person for the purposes of the AIM Rules for Companies. Mr. Owino has reviewed this announcement and consents to the inclusion in this announcement of the Kwale East exploration results and the supporting information in the form and context in which the relevant information appears. Figure 1: Kwale East Project location [A picture containing text, map, screenshot, diagram Description automatically generated] Figure 2: Kwale East Project drilling location [A map of the united states Description automatically generated] Appendix 1 Kwale East drill hole table All drill holes have dip of -90 degrees and azimuth of 0 degrees (i.e vertical). Local coordinates given to allow cross reference to cross sections, which are named after Local_Y. The table is sorted by a rounded Local_Y and then by Local_X. The reported intervals are combined ore zones averaged from the surface with a minimum 3m thickness that equals or exceed 1% HM. The reason for averaging from the surface is that the hydraulic mining method, which would likely be employed if any of this material were to be mined, results in the blending of the various ore zones. +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |Hole_ID|Type |Arc60_X|Arc60_Y |Local_X|Local_Y|DTM_Z|From|To |Interval|Avg|Avg |Avg | | | | | | | | | | | | | | | | | | | | | | | | | |HM |Slime|OS | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |MH348 |Auger|550,036|9,516,037|2,951 |10,650 |70 |0 |3 |3 |1.4|37.9 |0.9 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |MH347 |Auger|550,096|9,516,252|2,850 |10,850 |78 |0 |9 |9 |1.2|28.5 |0.7 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |MH349 |Auger|550,017|9,516,461|2,650 |10,950 |80 |0 |7.5 |7.5 |1.1|33.6 |0.8 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |MH350 |Auger|549,942|9,516,529|2,550 |10,950 |81 |0 |7.5 |7.5 |1.0|30.0 |1.0 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD052 |RCAC |551,503|9,515,640|4,300 |11,349 |52 |0 |7.5 |7.5 |1.0|18.7 |1.1 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD053 |RCAC |551,464|9,515,673|4,249 |11,347 |56 |0 |6 |6 |1.6|23.9 |1.9 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD054 |RCAC |551,430|9,515,708|4,201 |11,350 |56 |0 |4.5 |4.5 |1.7|38.4 |1.9 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD059 |RCAC |551,409|9,515,731|4,170 |11,353 |52 |0 |4.5 |4.5 |1.6|30.7 |1.8 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD046 |RCAC |551,502|9,515,710|4,252 |11,400 |57 |0 |7.5 |7.5 |1.3|24.6 |1.9 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD055 |RCAC |551,463|9,515,745|4,200 |11,399 |57 |0 |6 |6 |2.1|31.4 |2.6 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD058 |RCAC |551,435|9,515,774|4,160 |11,402 |52 |0 |3 |3 |1.6|18.6 |1.7 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD044 |RCAC |551,571|9,515,714|4,301 |11,449 |53 |0 |9 |9 |1.0|19.1 |1.0 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD045 |RCAC |551,534|9,515,749|4,250 |11,450 |58 |0 |6 |6 |1.7|21.4 |1.2 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD056 |RCAC |551,498|9,515,782|4,201 |11,450 |59 |0 |7.5 |7.5 |2.4|28.0 |2.7 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD057 |RCAC |551,460|9,515,816|4,150 |11,450 |53 |0 |4.5 |4.5 |1.8|29.4 |2.1 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD039 |RCAC |551,639|9,515,788|4,301 |11,550 |54 |0 |10.5|10.5 |1.5|22.3 |1.3 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD038 |RCAC |551,607|9,515,822|4,254 |11,553 |58 |0 |7.5 |7.5 |1.8|19.0 |0.9 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD037 |RCAC |551,564|9,515,856|4,200 |11,549 |62 |0 |9 |9 |1.7|24.9 |0.8 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+ |CD060 |RCAC |551,536|9,515,893|4,154 |11,558 |58 |0 |4.5 |4.5 |1.6|28.5 |1.8 | +-------+-----+-------+---------+-------+-------+-----+----+----+--------+---+-- ---+----+

Mining Lease No. 23 is adjacent to the PL. The SML boundary has been varied on multiple occasions, most recently to include the Bumamani Project deposits. The Kenyan Mining Act 2016 includes a provision for existing mineral rights to transition to mining licences upon their expiry on a priority basis. Landowner access permission is required to both complete the exploration program and then progress conversion of the PL to a mining licence. The Mining Act 2016 provides greater flexibility on securing land rights, specifically allowing for a mineral right to be issued on private land. The Mining Act 2016 additionally, provides for fair and adequate compensation to be paid to lawful landowners, occupiers and users.

Geology Deposit type, The Kwale East deposits geological are primarily hosted in setting and reddish dunal sands (Ore style of Zone 1) which is underlain mineralisation. by a transitional and occasionally lateritic zone (Ore Zone 4). To the east and around the 50 -60mRL, these deposits are hosted in shallow paleo -beach sands (Ore Zone 20) originating from a Pleistocene marine transgression event.

No metal equivalent values were used. Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. Relationship between These The deposit sequences are mineralisation widths and relationships sub-horizontal, and the intercept lengths are particularly vertically inclined holes important in the are a fair representation reporting of of true thickness. Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g., `down hole length, true width not known').
