The Company's Kwale Mineral Sands Operations in Kenya is located approximately 
50 kilometres south of Mombasa and 10 kilometres inland from the Kenyan coast. 
The Company's wholly owned subsidiary, Base Titanium, is the 100% owner and 
operator of Kwale Operations and has a net attributable interest of 100% in the 
2023 Kwale Mineral Resources and Ore Reserves estimates. Base Titanium also 
holds Prospecting Licence 2018/0119 and Special Mining Lease 23, which contain 
the Kwale South Dune, the Kwale North Dune and Bumamani deposits. 
 
Mineral Resources 
 
The 2023 Kwale Mineral Resources, as at 30 June 2023, are estimated to be 184Mt 
at an average HM grade of 1.5% for 2.8Mt of contained HM, at a 1% HM cut-off 
grade. 
 
The 2023 Kwale Mineral Resources estimate represents a decrease of approximately 
21Mt (or 10%) in material tonnes containing 0.7Mt of HM compared to the 2022 
Kwale Mineral Resources estimate.  This was due to mining depletion and 
sterilisation of the Kwale South Dune Mineral Resources and mining depletion of 
the Kwale North Dune Mineral Resources. 
 
The Kwale South Dune Mineral Resources are estimated to be 8.9Mt at an average 
HM grade of 2.2% for 0.19Mt of contained HM as at 30 June 2023, a decrease of 
18.8Mt containing 0.61Mt of HM compared to the 2022 Kwale South Dune Mineral 
Resources estimate. 
 
The 2023 Kwale North Dune Mineral Resources are estimated to be 169Mt at an 
average HM grade of 1.5% for 2.51Mt of contained HM as at 30 June 2023, a 
decrease of 2.4Mt containing 0.05Mt of HM compared to the 2022 Kwale North Dune 
Mineral Resources estimate. 
 
The 2023 Bumamani Mineral Resources are estimated to be 5.9Mt at an average HM 
grade of 1.9% for 0.12Mt of contained HM.  The Bumamani Mineral Resources at 30 
June 2023 are unchanged from the 2022 estimate.

Ore Reserves 
 
Included within the Kwale Mineral Resources are the Kwale Ore Reserves, 
estimated to be 21.3Mt at an average HMgrade of 2.2% for 0.48Mt of contained HM 
as at 30 June 2023. 
 
Compared to the 2022 Kwale Ore Reserves estimate, there was a decrease of 56% in 
contained HM tonnes. 
 
The Kwale South Dune Ore Reserves decreased by 16.9Mt containing 0.57Mt of HM 
due to mining depletion and sterilisation of unmined material due to a 
combination of an elevated basement floor in some areas compared to that 
predicted in the underlying model, induration at the base of the mineralised 
profile that could not be readily mined and infrastructure buffers. 
 
The Kwale North Dune Ore Reserves decreased by 1.8Mt containing 0.04Mt of HM due 
to mining depletion.  There was no sterilisation of unmined material as the 
design pit floor is yet to be reached.

Ranobe Deposit 
 
The Company's Toliara Project is based on the Ranobe deposit, located 
approximately 45 kilometres north of the town of Toliara and 15km inland from 
the coast in south-west Madagascar.  The Ranobe deposit sits within Permis 
d'Exploitation 37242, which is a mining lease under Malagasy law.  The Company's 
wholly owned subsidiary, Base Toliara SARL, is the 100% owner and operator of 
the Toliara Project and has a net attributable interest of 100% in the 2023 
Ranobe Mineral Resources and Ore Reserves estimates.  The Company is currently 
progressing the project towards development. 
 
Mineral Resources 
 
The 2023 Ranobe Mineral Resources was unchanged from the 2022 estimate of 
2,580Mt at an average HM grade of 4.3% for 111Mt of contained HM, based on a 
1.5% HM cut-off grade.

Ore Reserves 
 
Included within the Ranobe Mineral Resources are the Ranobe Ore Reserves, 
estimated to be 904Mt at an average HM grade of 6.1% for 55Mt of contained HM as 
at 30 June 2023, which are unchanged from the 2022 estimate.  No monazite or 
garnet is incorporated in the Ranobe Ore Reserves estimate because the existing

Mineral Resources and Ore Reserves Governance 
 
A summary of the governance, internal controls and estimation process applicable 
to Base Resources' Mineral Resources and Ore Reserves estimates is as follows: 
 
Mineral Resources 
 
  · Review and validation of drilling and sampling methodology and data spacing, 
geological logging, data collection and storage, sampling and analytical quality 
control. 
  · Geological interpretation - review of known and interpreted structure, 
lithology and weathering controls. 
  · Estimation methodology - relevant to mineralisation style and proposed 
mining methodology. 
  · Comparison of estimation results with previous mineral resources models, and 
with results using alternate modelling methodologies. 
  · Visual validation of block model against raw composite data. 
  · Use of external Competent Persons to assist in preparation of Mineral 
Resources estimate updates. 
 
Ore Reserves 
 
  · Review of potential mining methodology to suit deposit and mineralisation 
characteristics. 
  · Review of potential Modifying Factors, including cost assumptions and 
commodity prices to be utilised in mining evaluation. 
  · Ore Reserves estimate updates initiated following material changes in the 
relevant Modifying Factor assumptions. 
  · Optimisation using appropriate software packages for open pit evaluation. 
  · Design based on optimisation results. 
  · Use of external Competent Persons to assist in preparation of Ore Reserves 
estimates.

Forward looking statements 
 
Certain statements in or in connection with this statement contain or comprise 
forward looking statements.  Such statements may include, but are not limited 
to, statements with regard to future production and grades, capital cost, 
capacity, sales projections and financial performance and may be (but are not 
necessarily) identified by the use of phrases such as "will", "expect", 
"anticipate", "believe" and "envisage".  By their nature, forward looking 
statements involve risk and uncertainty because they relate to events and depend 
on circumstances that will occur in the future and may be outside Base 
Resources' control.  Accordingly, results could differ materially from those set 
out in the forward-looking statements as a result of, among other factors, 
changes in economic and market conditions, success of business and operating 
initiatives, changes in the regulatory environment and other government actions, 
fluctuations in product prices and exchange rates and business and operational 
risk management.  Subject to any continuing obligations under applicable law or 
relevant stock exchange listing rules, Base Resources undertakes no obligation 
to update publicly or release any revisions to these forward-looking statements 
to reflect events or circumstances after today's date or to reflect the 
occurrence of unanticipated events. 
 
Glossary 
 
[] 
Assemblage     The relative proportion of heavy mineral components, 
               principally ilmenite, rutile, zircon and, where applicable, 
               leucoxene, monazite and garnet.

Competent      The JORC Code requires that a Competent Person be a Member or 
Person         Fellow of The Australasian Institute of Mining and Metallurgy, 
               of the Australian Institute of Geoscientists, or of a 
               `Recognised Professional Organisation'.  A Competent Person 
               must have a minimum of five years' experience working with the 
               style of mineralisation or type of deposit under consideration 
               and relevant to the activity which that person is undertaking. 
Cut-off grade  The lowest grade of mineralised material that is thought to be 
               economically mineable and available.  Typically used by Base 
               Resources to define which material is reported in a Mineral 
               Resources estimate. 
GARN           Garnet, a valuable heavy mineral. 
Grade          A physical or chemical measurement of the characteristics of 
               the material of interest.  In this context, the grade is always 
               a percentage and the characteristics are heavy mineral, 
               oversize, slime and the various product minerals (ilmenite, 
               rutile etc). 
Heavy mineral  In mineral sands, minerals with a specific gravity greater than 
or HM          2.85 t/m[3]. 
ILM            Ilmenite, a valuable heavy mineral. 
Indicated      An Indicated Mineral Resource is that part of a Mineral 
               Resource for which quantity, grade (or quality), densities, 
               shape and physical characteristics are estimated with 
               sufficient confidence to allow the application of Modifying 
               Factors in sufficient detail to support mine planning and 
               evaluation of the economic viability of the deposit. 
Inferred       An Inferred Mineral Resource is that part of a Mineral Resource 
               for which quantity and grade (or quality) are estimated on the 
               basis of limited geological evidence and sampling.  Geological 
               evidence is sufficient to imply but not verify geological and 
               grade (or quality) continuity.  It is based on exploration, 
               sampling and testing information gathered through appropriate 
               techniques from locations such as outcrops, trenches, pits, 
               workings and drill holes. 
JORC Code      The Australasian Code for Reporting of Exploration Results, 
               Mineral Resources and Ore Reserves 2012 Edition, as published 
               by the Joint Ore Reserves Committee of The Australasian 
               Institute of Mining and Metallurgy, Australian Institute of 
               Geoscientists and Minerals Council of Australia. 
LEUC           Leucoxene, a valuable heavy mineral. 
Measured       A Measured Mineral Resource is that part of a Mineral Resource 
               for which quantity, grade (or quality), densities, shape, and 
               physical characteristics are estimated with confidence 
               sufficient to allow the application of Modifying Factors to 
               support detailed mine planning and final evaluation of the 
               economic viability of the deposit. 
Mineral        Mineral Resources are a concentration or occurrence of solid 
Resources      material of economic interest in or on the Earth's crust in 
               such form, grade (or quality), and quantity that there are 
               reasonable prospects for eventual economic extraction.  The 
               location, quantity, grade (or quality), continuity and other 
               geological characteristics of a Mineral Resource are known, 
               estimated or interpreted from specific geological evidence and 
               knowledge, including sampling.  Mineral Resources are sub 
               -divided, in order of increasing geological confidence, into 
               Inferred, Indicated and Measured categories. 
Modifying      Modifying Factors are considerations used to convert Mineral 
Factors        Resources to Ore Reserves.  These include, but are not 
               restricted to, mining, processing, metallurgical, 
               infrastructure, economic, marketing, legal, environmental, 
               social and governmental factors. 
MON            Monazite, a valuable heavy mineral that contains rare earth 
               elements. 
Ore Reserves   Ore Reserves are the economically mineable part of a Measured 
               and/or Indicated Mineral Resource.  It includes diluting 
               materials and allowances for losses, which may occur when the 
               material is mined or extracted and is defined by studies at Pre 
               -Feasibility or Feasibility level as appropriate that include 
               application of Modifying Factors. Such studies demonstrate 
               that, at the time of reporting, extraction could reasonably be 
               justified. 
OS             Oversize material, for Kwale and Ranobe it is defined as 
               material >1mm in size 
Probable       A Probable Ore Reserve is the economically mineable part of an 
               Indicated, and in some circumstances, a Measured Mineral 
               Resource.  The confidence in the Modifying Factors applying to 
               a Probable Ore Reserve is lower than that applying to a Proved 
               Ore Reserve. 
Proved         A Proved Ore Reserve is the economically mineable part of a 
               Measured Mineral Resource.  A Proved Ore Reserve implies a high 
               degree of confidence in the Modifying Factors. 
RUT            Rutile, a valuable heavy mineral. 
SL             Slimes, fine material (defined as <45µm at Kwale and <63µm at 
               Ranobe) that is a waste product from the processing of mineral 
               sands. 
Sterilisation  Material that is depleted from Mineral Resources or Ore 
               Reserves, but which was not mined.  This material still remains 
               in ground following mining activity and, in the Competent 
               Person's opinion, it has no reasonable prospects for eventual 
               economic extraction. 
ZIR            Zircon, a valuable heavy mineral.S.
