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.

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.

|
| | | · Staff were trained to use
|

|
| | |rather than manipulate sample
|
| | |through slimes screen by hand to
|
| | |remove the potential for screen
|
| | |damage.
|
| | | · A calibration schedule was
|
| | |introduced for scales used in the
|
| | |sample preparation stage.
|
| | | · The introduction of LIMS
|
| | |software allowed the capture of
|
| | |sample preparation data digitally
|
| | |at inception and synchronisation
|
| | |in real-time to the master Kwale
|

|
| | |
|
| | |The sample preparation flow sheet
|
| | |follows conventional mineral
sands|
| | |processes but departed from
|
| | |standard mineral sand practices
in|
| | |one respect; the samples were
|
| | |generally not oven dried prior to
|
| | |de-sliming to prevent clay
|
| | |minerals being baked onto the HM
|
| | |grains (because the HM fractions
|
| | |were to be used in further
|
| | |mineralogical test work).
|
| | |Instead, a separate sample was
|
| | |split and dried to determine
|
| | |moisture content, which was
|
| | |accounted for mathematically.
|
| | |
|
| | |Pre-soaking of the sample TSPP

more|
| | |efficient de-sliming process and
|
| | |avoided potentially under

|
| | |
|
| | |QA/QC procedures involved the
|
| | |following:

|
| | | · Prepared laboratory duplicate
|
| | |split samples were processed at

| | |every 20th sample.
|
| | | · Prepared laboratory repeat
|

|
