Kwale East exploration drilling update
Key Points * Three areas of mineralisation have been identified for further targeted exploration – Magaoni, Masindeni and Zigira. This follows results from 1,019 holes drilled for a total of 11,536.5m as part of the Phase 1 scout auger drilling program at the Kwale East project, adjacent to Kwale Operations.
* Access for exploration remains constrained, including to the highly prospective areas of Magaoni and Zigira, with landowner consents yet to be obtained for ~35% of these areas.
* A Phase 2 air core drilling program, focusing on the three identified exploration targets, will commence shortly. As part of this program, the remaining ~35% of Magaoni and Zigira will be drilled as landholder consents are obtained and all Phase 1 auger holes with an average heavy mineral grade greater than 1% will be twinned to enable better sample quality and allow drilling through to basement.
* Notable drill hole intercepts from surface included: * KE464 - 7.5m at an average grade of 6.3% HM in Zigira.
* KE392 - 9m at an average grade of 4.3% HM in Zigira.
* MH183 - 13.5m at an average grade of 3.9% HM in Magaoni.
* KE693 – 13.5m at an average grade of 3.5% HM in Magaoni.
* MH181 – 15m at an average grade of 3.4% HM in Magaoni.
* Mineral assemblage analysis indicates elevated concentrations of rutile and zircon relative to the Kwale deposits currently being mined, with average ilmenite of 52%, rutile of 18% and zircon of 10% of the heavy mineral content.
Base Resources Limited (ASX & AIM: BSE) (Base Resources or the Company) is
pleased to release initial assay results from the first phase of scout auger
drilling at its Kwale East exploration project (Kwale East) in Kwale County,
Kenya (Phase 1).
Kwale East is located within Prospecting Licence 2018/0119 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.
Kwale East is located to the immediate east of the Company’s Kwale
Operations, with distances from Kwale Operations’ processing facilities
ranging from 2 to 6 km – refer to Figure 1. Kwale East’s close proximity
to Kwale Operations’ infrastructure makes it a near-term mine life extension
opportunity.
Details about exploration activities
Exploration at Kwale East started in 2015 when a regional mapping exercise and
desktop geological, geographical and geomorphological investigations of the
mineral potential of the late Pliocene sediments were carried out.
Historical geophysical surveys were reviewed but found to be insufficiently
resolved. Consequently, a new airborne survey was commissioned to cover the
southern coastal plain, from Mombasa to the Tanzanian border, as aeromagnetic
and radiometric surveys are known to be effective tools for exploration of
strand and dune deposits. Scout drilling targets were subsequently
identified from coincident geophysical anomalism and compelling
geomorphological features.
In 2018, a 400m north by 100m east scout air core drilling program was
completed in the northern part of Kwale East and 123 holes for 1,851.5m were
drilled, with no significant continuous mineralisation intersected. This
program did not extend over other portions of Kwale East, as landowner
consents for those areas were not forthcoming at that time.
Following a lengthy and concerted community engagement and sensitisation
program, further landowner consents began to be obtained and a scout auger
drilling program was commenced over other portions of Kwale East in October
2022. While landowner consents for large portions of Kwale East have been
obtained, access to all targeted drilling areas is yet to be obtained. Land
access is a particular challenge in Magaoni and Zigira, with access to
approximately 35% of the targeted areas yet to be obtained. Based on
drilling to date, the areas where access is yet to be obtained appear to cover
highly prospective areas – refer to Figure 2. Focused community engagement
seeking the remaining landowner consents is ongoing and remains positive.
The scout auger drilling was undertaken using the Company’s own auger rigs
and personnel and covered broad areas in order to establish mineralised trends
for follow-up drilling with an air core rig in the second phase of the
program. Drillhole spacing was fluid and dependant on land access.
However, where blanket access was obtained either a 100m north-south x 100m
east-west grid or a 100m north-south x 50m east-west grid was achieved,
depending on landowner expectations. As at 27 June 2023, a total of 1,019
auger drill holes for 11,536.5m generating 7,691 samples, at a 1.5m downhole
sample interval, have been analysed. A further 38 auger drill holes for 391m
have been completed, with assays results pending. Refer to Figure 2 for the
drill hole locations.
All assays were completed at the Kwale Operations laboratory.
Kwale East auger drilling activities
Results from Phase 1 drilling
Phase 1 assays confirmed the presence of HM within the different mineralised
geological domains, with a peak drill hole grade of 6.3% HM, as well as a high
value mineral assemblage.
Three targets – Magaoni, Masindeni and Zigira – were identified for
follow-up drilling in phase 2 – refer to Figure 2 for the location of these
targeted areas. The considerations for target identification were grade
tenor (assuming a 1% HM economic cut-off grade), as well as reasonable lateral
and downhole continuity in mineralisation.
Drill logging identified four primary geological domains. These are
described below, also refer to Figure 3 for a type section by geological
domain, Figure 4.1 for a plan view of the drill hole sections and Figures 4.2
to 4.21 for specific cross sections across each of the Magaoni, Masindeni and
Zigira target areas.
* Ore Zone 1 – Reddish-brown dunal sands, comprising approximately 60% of
the project volume, with thicknesses of up to 18m. This zone also has the
highest HM grades. Geologically referred to as the Margarini Formation, it
is ubiquitous in the highland areas of the south-east Kenya and northern
Tanzanian coast and is thought to have been deposited as coastal dunes under
conditions of intense aridification and erosion.
* Ore Zone 4 – Ore Zone 4 lies below Ore Zone 1 and has a distinct
geological contact believed to represent a palaeo-surface. Ore Zone 4 is
often dominated by clayey-sands and variable laterisation and HM concentration
is generally reduced. The occurrence of this layer is usually not correlated
with a change in the colour of sand and it may also occur at the contact with
the basement. Ore Zone 4 has been domained separately to Ore Zone 1, as the
quality of mineralisation is generally poorer than Ore Zone 1.
* Ore Zone 20 – Ore Zone 20 is a low-slime paleo-beach sand unit
representing the Pleistocene marine-cut platform between the 40-60m RL. This
marine transgression likely reworked the existing deposits, locally
concentrating them into high-grade deposits. The wave action also likely
winnowed out the lighter heavy minerals like Kyanite, Garnet and Tourmaline
and upgraded the ilmenite product by leaching out iron.
* Basement – The basement at Kwale East is a poorly-sorted, weathered, clay,
clay sand and sand. Further to the east, a coralline limestone basement is
typically encountered. Grainsize range from clay to pebbles. It is
variably coloured in hues of red, grey and cream and carries a background
concentration of HM. It shows a poor mineral assemblage with an increased
incidence of Garnet and Kyanite. There is localised induration at the upper
contact and intersection of white sand and clay is common.
The three Ore Zones have demonstrated economic potential following encouraging
initial HM assay results. Analysis also indicates high value mineral
assemblages, with average ilmenite of 52%, rutile of 18% and zircon of 10% of
the heavy mineral content. That said, the generally shallow thickness of Ore
Zone 20 may limit the tonnage potential and development where it is the
primary host material. There are also some high-slime areas in Magaoni and
Masindeni which may limit development potential due to slime tails disposal
constraints.
Notable auger drill hole intercepts from surface across all the Ore Zones from
each of the target areas are set out below.
Magaoni:
* MH183 13.5m at 3.9% HM
* KE693 13.5m at 3.5% HM
* MH181 15m at 3.4% HM
* KE804 18m at 2.5% HM
Zigira:
* KE464 7.5m at 6.3% HM
* KE568 7.5m at 4.5% HM
* KE392 9m at 4.3% HM
* KE461 10.5m at 2.5% HM
Masindeni:
* NE063 12m at 2.1% HM
* NE030 10.5m at 2.1% HM
* NE067 13.5m at 1.6% HM
For further details about the Phase 1 exploration results, refer to the
Appendices to this announcement, comprising a table of assay results for all
drill holes exceeding an average grade of 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). A glossary of key terms used in this
announcement is also contained below.
Phase 2 air core drilling and other planned activities
A phase 2 follow-up drill program is expected to commence in early July 2023
using an EVH 2100 air core rig (Phase 2) focusing on the three identified
target areas and involve:
* drilling the remaining ~35% of the Magaoni and Zigira target areas that were
not drilled in Phase 1 on a priority basis, as landowner consents are
obtained;
* infill drilling to achieve 100m north by 50m east spacing; and
* twinning all Phase 1 auger holes with average HM grades of greater than 1%
to enable better sample quality and allow drilling through to basement.
Issues with the Phase 1 auger method included coarser material being
under-represented in samples, holes collapsing in wet ground and the
possibility of sample contamination as the auger string is pulled from the
ground. The auger drilling samples are not considered appropriate for
resource estimation purposes, but have successfully delineated areas of
interest for Phase 2 air core drilling.
As mentioned above, focused community engagement to secure exploration access
to the remaining portions of the targeted areas is ongoing and remains
positive.
Other planned activities to assist with assessment and determination of any
Mineral Resources estimate are as follows:
* Extension of the LIDAR DTM survey at 2m spatial resolution to cover the
eastern part of Kwale East.
* Undertaking microscopic heavy mineral logging to identify gross
mineralogical changes and aid in creating robust geological boundaries.
* Collecting large samples from test pits for bulk metallurgical and
processing test work.

Table 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 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.

JORC Code - Section 1 Sampling Techniques and Data
Criteria Explanation Comment
Sampling techniques Nature and quality of sampling (e.g., cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under Mechanised auger drilling was used to obtain 1.5m samples from which approximately 4.0kg was collected via composite grab sampling of a homogenised sample to produce a sub-sample for HM analysis utilising heavy liquid separation, magnetic separation and XRF assay. All holes were sampled over consistent 1.5m intervals. Several programs of twin drilling of air core holes have been undertaken and, while some variability was observed, it was concluded that auger drilling is appropriate for reconnaissance drilling to identify mineralisation potential. Samples were analysed by mineral sands industry standard techniques of screening, desliming and heavy liquid separation using SPT (sodium polytungstate: SG = 2.85g/cm3). XRF analysis of HM magnetic fractions was used to define the VHM content.

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 (e.g., submarine nodules) may warrant disclosure of
detailed information.
Drilling techniques Drill type (e.g., core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g., core diameter, triple or standard tube, All holes were drilled using trailer mounted mechanised auger equipment, with the fleet comprising 3 rigs utilising dead stick auger method (0.5m sample runs) and 1 rig utilising continuous flight auger method. All holes were drilled vertically with the trailer levelled using site preparation and manual jack legs. Hole diameter was approximately 4” or 102 mm

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 Sample condition was logged at the rig as either good, moderate or poor, with good meaning not contaminated and appropriate sample size (recovery), moderate meaning not contaminated, but sample over or under sized, and poor meaning contaminated or grossly over/undersized. It is recognised that open hole auger drilling is subject to potential sample contamination by smearing as the sample is retrieved (both methods) and material falling downhole during running of the drill string (dead stick method). To counter downhole contamination the driller nominates material for rejection as potential contamination on each 0.5m drill run. No relationship is believed to exist between grade and sample recovery. No bias is also believed to occur due to loss of fine material.
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.
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 All samples were visually checked on site and a summary log completed by the rig geologist, with detailed logging occurring off-site at a later date to avoid speculation by community observers. Samples are logged for lithotype, grain size, colour, hardness, and moisture content. Logging was based on a representative grab sample that was panned for heavy mineral estimation and host material observations. Logging codes were developed into Base Titanium process documents to capture observations on lithology, colour, grainsize, induration and estimated mineralisation. Any relevant comments e.g., water table, hardness, gangue HM components and stratigraphic markers (e.g fossilised wood) were included to aid in the subsequent geological modelling.
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.
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. An approximate 25% split of the drilled sample interval is collected on site via manual cone and quarter composite grab sampling. This sample is taken to a dedicated sample preparation facility where it is air-dried when weather permits, otherwise oven dried during rains. After drying, the sample is rotary split to produce a ~200-400g sample for processing. The remaining drill sample material is combined and split down to ~2-3kgs for storage. Improvements to the sample preparation stage were made in recent years to ensure industry best practice and to deliver a high degree of confidence in the results. These included the following: * A formalised process flow was generated, posted in all sample preparation areas and used to train and monitor sample preparation staff.

field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. * TSPP was introduced to decrease attrition time and improve slimes recovery. A range of attrition times (with 5% TSPP) were trialled and plotted against slimes recovery figures to determine optimum attrition time (15 minutes).
* Staff were trained to use paint brushes and water spray 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 Laboratory database.
* Slimes screen number recorded to isolate batches should re-assay be required due to poor adherence to procedure or to identify screen damage.
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 dispersant solution ensured a more efficient de-sliming process and to avoid potentially under-reporting slimes content. QA/QC procedures involved the following: * Prepared laboratory duplicate samples are processed at every 20th sample.
* Prepared laboratory repeat samples are completed at every 7th sample.
The manual hard-copy sample preparation records are maintained in files in the event of cross-references due to identified scribing errors into LIMS software. The sample size is considered appropriate for the grain size of the material because the grade of HM is measured in per cent.
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, Samples were analysed by conventional mineral sands techniques of screening, desliming and heavy liquid separation using SPT (sodium polytungstate: SG = 2.85g/cm3). XRF analysis of HM magnetic fractions was used to define the VHM content. All drill samples were submitted to the Base Titanium laboratory at the Kwale mine site in Kenya.

* Various quality control samples were submitted routinely to assure assay quality. A total of 429 duplicate field samples, 160 preprepared laboratory duplicate samples and an unspecified number of internal laboratory standards, repeats and blanks have been assayed at Kwale Operations’ site laboratory.
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 Drill hole logging and site sample data is collected electronically in Maxwell LogChief software, installed on Panasonic Tough pads and which synchronise directly to the Maxwell DataShed exploration database hosted on the Base Titanium network server. Assay data is captured electronically via LIMS software and merged with logging and sample data in Datashed. No adjustment to assay data has been made.
procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data.
Location of data points Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource Proposed drill holes were sited on the ground using hand-held GPS and drill collars surveyed using the same instrumentation. DGPS RTK surveys will be employed for the follow-up resource drilling collars to enable JORC Code compliant resource estimates. The survey Geodetic datum utilised was UTM Arc 1960, used in East Africa Arc 1960 references the Clark 1880 (RGS) ellipsoid and the Greenwich prime meridian. All survey data used has undergone a transformation to the local mine grid from the standard UTM Zone 37S (Arc 1960). The local Grid is rotated 42.5 o , which aligns the average strike of the deposit with local North and is useful for both grade interpolation and mining reference during production. The drill collars were projected to a combined local LIDAR and SRTM digital terrain model
estimation. Specification of the grid system used. Quality and adequacy of topographic control.
Data spacing and distribution Data spacing for reporting of Exploration Results. Whether the data spacing, and distribution is sufficient to establish the degree of geological and grade continuity The drill data spacing for the drilling was nominally 100m X, 100m Y and 1.5m Z. Variations from this spacing resulted from access challenges. A sample interval of 1.5m was employed in the 2018 air core and 2023 auger drilling campaign by Base Titanium. This spacing and distribution is considered sufficient to establish the degree of geological and mineralisation continuity appropriate for reconnaissance exploration. No sample compositing has been applied for HM, slimes, oversize and XRF assays.
appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied.
Orientation of data in relation to geological structure Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the With the geological setting being a layered dunal/fluvial/maritime sequences, the orientation of the deposit mineralisation in general is sub-horizontal. All drill holes were orientated vertically to penetrate the sub-horizontal mineralisation orthogonally. Hole centres were spaced nominally at 50-200m. This cross-profiles the dune so that variation can be determined. Down hole intervals were nominated as 1.5m. This provides adequate sampling resolution to capture the distribution and variability of geology units and mineralisation encountered vertically down hole. The orientation of the drilling is considered appropriate for testing the horizontal and vertical extent of mineralisation without bias.
relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed
and reported if material.
Sample security The measures taken to ensure sample security. Sample residues from the preparatory stage were transferred to pallets and stored in a locked shed beside the warehouse at Kwale Operations. Residues from the Kwale Operations site laboratory were placed in labelled bags and stored in numbered boxes. Boxes were placed into a locked container beside the laboratory. Sample tables are housed on a secure, network-hosted SQL database. Full access rights are only granted to the Exploration Manager and senior IT personnel. Data is backed up every 12 hours and stored in perpetuity on a secure, site backup server.
Audits or reviews The results of any audits or reviews of sampling techniques and data. In-house reviews were undertaken by the Mr. Scott Carruthers and Mr. Ian Reudavey, both employees of the Base Resources group Competent Persons under the JORC Code.
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
Criteria Explanation Comment
Mineral tenement and land tenure status Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. The Kwale East exploration area is situated on a Prospecting Licence 100% owned by Base Titanium– PL/2018/0119 located in Kwale County, Kenya. Base Titanium is a wholly
owned subsidiary of Australian and AIM-listed resources company, Base Resources. The 40km 2 Prospecting Licence was re-granted on 26 of May 2021 for a second, three-year
term ending 25 May 2024. The PL is in good standing with the Kenya Ministry of Petroleum & Mining at the time of reporting, with all statutory reporting and payments up
to date. Local landowners have been generally supportive of exploration activities though blanket access is yet to be achieved. With the support of government and local
leaders, engagement continues with community members to secure drilling access to the remaining targeted areas. The existing Special Mining Lease No. 23 is adjacent to
the PL and covers the original Kwale Central and Kwale South deposits. 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. The
potential for this transition has been raised with the Government of Kenya in preparation for a possible application. Landowner access permission is required to both
complete the exploration program and then progress conversion of the PL to a mining licence within a timeframe that meets Kwale Operations’ operational requirements. 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.
Exploration done by other parties Acknowledgment and appraisal of exploration by other parties. No historical exploration by third parties was undertaken in the Kwale East area.
Geology Deposit type, geological setting and style of mineralisation. The Kwale East deposits are primarily hosted in reddish dunal sands (Ore Zone 1) which is underlain by the 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 originating from a Pleistocene marine transgression event. This zone is low in
slime and typically has a high valuable heavy mineralogy content. All three formations have a regional strike direction of about 40 degrees East of North and range in age
from mid-Pliocene to Pleistocene.
Drill hole Information A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: * easting and northing of the drill hole collar A tabulation of drilling data with significant intersections >1% HM is presented as Appendix 1, Table 1. All drill hole locations are shown in Figure 3, and those holes
* elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar not tabulated have not reported significant intersections. The exclusion of detailed collar information is justified on the basis that auger drilling represents a
* dip and azimuth of the hole reconnaissance exploration tool and that air core drilling will be utilised to twin and infill areas identified as prospective by the auger drilling program. A
* down hole length and interception depth comprehensive set of drilling cross sections is presented in Figure 4 that allows additional understanding of the exploration results. Drilling by year (max, min and
* hole length. average depths) are as follows. * 2018/2019
If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. * 123 air core drill holes (depth: max 33m, min 6m, avg 15m).
* Total 1,851.5m drilled
* 2023
* 1,019 auger drill holes (depth: max 22.5m, min 3m, avg 11.5m).
* Total 11,536.5m drilled
All drill holes are drilled vertically (-90 degrees). All collars have been projected to the DTM surface.
Data aggregation methods In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g., cutting of high grades) and cut-off grades are usually Material and should be stated. 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. Exploration results are reported as length weighted averages from surface. No grade cutting has been applied and a nominal cut-off grade of 1% HM has been utilised.
However, lower grade intervals may be included to provide geological continuity and in recognition of bulk mining techniques used for mineral sands. No metal equivalent
values were used.
Relationship between mineralisation widths and intercept lengths These relationships are particularly important in the reporting of 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’). The deposit sequences are sub-horizontal, and the vertically inclined holes are a fair representation of true thickness.
Diagrams Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. See body of the announcement - Figures 2 and 4.
Balanced reporting Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. Drill sections include all available HM assay results of composited Ore Zone 1, Ore Zone 4 and Ore Zone 20 for all drill holes and the drilling location plan shows the
average HM assay results for all drill holes.
Other substantive exploration data Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. Geological observations suggest that the Kwale East dunal material contains lower slimes than current being mined, and this will be beneficial to support co-disposal of
tails, while still having sufficient slimes to support hydraulic mining. Many of the auger holes did not reach the basement owing to drilling challenges and follow-up air
core drilling to this formation will likely increase the currently observed mineralisation thickness.
Further work The nature and scale of planned further work (e.g., tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. Twinning of mineralised auger holes and infilling mineralised areas with air core holes to ensure data confidence/ integrity for JORC Code compliant resource estimates.
This drilling will be completed at a 100m North by 50m East grid to achieve measured/indicated resource categorisations. LIDAR topographical survey to cover the eastern
Zigira prospect at a 2m spatial resolution. Test pits for bulk sample mineralogy test work. Logging of HM sink fractions to aid in geological domaining.
