2021 Mineral Resources and Ore Reserves Statement
Key Points
- Kwale South Dune Ore Reserves estimate updated to incorporate existing estimated Mineral Resources located within the proposed expanded Kwale Special Mining Lease 23, increasing ore by 19Mt and contained heavy mineral by 0.6Mt and taking Kwale mine life to December 2023 following such expansion.
- Kwale South Dune Mineral Resources and Ore Reserves estimates reduced by mining depletion during the year to 30 June 2021.
- The combined effect is that:
- estimated South Dune Mineral Resources have reduced by 22Mt containing 0.7Mt of in situ heavy mineral; and
- estimated South Dune Ore Reserves remain the same at 40Mt of ore but contained heavy mineral has reduced by 0.1Mt.
- Kwale North Dune Mineral Resources estimate update announced on 19 February 2021 increased the estimate to 194Mt at an average heavy mineral grade of 1.5%, containing 2.9Mt of heavy mineral.
- Maiden Kwale Bumamani Mineral Resources estimate also announced on 19 February 2021 of 5.9Mt at an average heavy mineral grade of 1.9%, containing 0.115Mt of heavy mineral.

KWALE DEPOSITS
The Company’s 100% owned 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, holds Prospecting Licence 2018/0119 (PL119) which contains the Kwale South Dune, and the Kwale North Dune and Bumamani deposits. A portion of the Kwale South Dune deposit resides within Base Titanium’s Special Mining Lease 23 (SML 23) with the remainder sitting within PL119 but outside SML 23. The Company is in the process of completing the necessary steps to effect the expansion of SML 23 to cover the estimated Kwale South Dune Mineral Resources that are presently outside that mining tenure, but within PL119.
A pre-feasibility study is also currently underway to assess the potential to mine higher grade sub-sets of the North Dune deposit and the Bumamani deposit.
Base Resources is the operator of Kwale Operations and has a net attributable interest of 100% in the 2021 Kwale Mineral Resources and Ore Reserves estimates.
Mineral Resources
The 2021 Kwale Mineral Resources, as at 30 June 2021, are estimated to be 254 million tonnes (Mt) at an average heavy mineral (HM) grade of 1.9% for 4.7Mt of contained HM, at a 1% HM cut-off grade.

Table subject to rounding differences.
The 2021 Kwale Mineral Resources estimate represents an increase of approximately 3% in material tonnes but a decrease of 4% in contained HM tonnes when compared with the 2020 Kwale Mineral Resources estimate. This is due to an increase in the Kwale North Dune Mineral Resources estimate and the addition of the maiden Bumamani Mineral Resources estimate, offset by Kwale South Dune mining depletion.
The Kwale South Dune Mineral Resources are estimated to be 54Mt at an average HM grade of 3.2% for 1.7Mt of contained HM as at 30 June 2021, a decrease of 22Mt containing 0.7Mt of HM due to mining depletion, inclusive of sterilisation of sub-economic low-grade material, when compared with the 2020 Kwale South Dune Mineral Resources estimate.
The 2021 Kwale North Dune Mineral Resources estimate was updated on 19 February 2021 and are estimated to be 194Mt at an average HM grade of 1.5% for 2.9Mt of contained HM, at a 1% HM cut-off grade, an increase in material tonnage of 13% and contained HM of 12%, when compared to the 2020 Kwale North Dune Mineral Resources estimate.
The maiden 2021 Bumamani Mineral Resources estimate was released on 19 February 2021 and is estimated to be 5.9Mt at an average HM grade of 1.9% for 0.115Mt of contained HM, at a 1% HM cut-off grade.
Ore Reserves
Contained within the Kwale South Dune Mineral Resources are the Kwale South Dune Ore Reserves, estimated as at 30 June 2021 to be 40Mt at an average HM grade of 3.3% for 1.3Mt of contained HM.

Table subject to rounding differences.
While ore tonnage did not change, the 2021 Kwale South Dune Ore Reserves estimate represents an overall decrease of 2% in contained HM tonnes from the previously reported 2020 Kwale South Dune Ore Reserves estimate due to:
- depletion due to mining of 19Mt of ore and 0.7Mt of contained HM, inclusive of unmined material caused by an elevated basement floor in some areas compared to that predicted in the underlying model; and
- an additional 19Mt of ore and 0.6Mt of contained HM being included as a result of incorporation of additional Kwale South Dune Mineral Resources located within the proposed expanded SML 23.
The additional Kwale South Mineral Resources were incorporated given the Company’s greater certainty that, in the near term, mining tenure arrangements with the Kenyan Ministry of Petroleum and Mining for the proposed extended SML23 will be finalised, and the necessary environmental licencing (an EIA Licence) will be issued.
No Ore Reserves estimate has been completed for the Kwale North Dune and Bumamani deposits.
RANOBE DEPOSIT
The Company’s 100% owned 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 is currently progressing the project towards development.
Base Resources is the operator of the Toliara Project and has a net attributable interest of 100% in the 2021 Ranobe Mineral Resources and Ore Reserves estimates.
Mineral Resources
The 2021 Ranobe Mineral Resources are estimated to be 1,293Mt at an average HM grade of 5.1% for 66Mt of contained HM, based on a 1.5% HM cut-off grade. The Ranobe Mineral Resources at 30 June 2021 are unchanged from the 2020 estimate.

Glossary
| Assemblage | The relative proportion of valuable heavy mineral components of ilmenite, rutile, zircon and, where applicable, leucoxene. | |
| Base Resources or Company | Base Resources Limited. | |
| Base Titanium | Base Titanium Limited. | |
| Competent Person | The JORC Code requires that a Competent Person be a Member or 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 Resource estimate. | |
| 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 2.85 t/m3. | |
| 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. | |
| Modifying Factors | Modifying Factors are considerations used to convert Mineral Resources to Ore Reserves. These include, but are not restricted to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors. | |
| Mineral Resources | Mineral Resources are a concentration or occurrence of solid 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. | |
| Ore Reserves | Ore Reserves are those portions of Mineral Resources that, after the application of all Modifying Factors, result in an estimated tonnage and grade which, in the opinion of the Competent Person making the estimates, are economically mineable. | |
| OS | Oversize material. | |
| 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, being a waste product from the processing of mineral sands. | |
| Sterilisation | Material or Ore that is depleted from Mineral Resources or Ore Reserves, but which was not mined. This material still remains in ground but mining has passed by and, in the competent person’s opinion, it has no reasonable prospects for eventual economic extraction. | |
| ZIR | Zircon, a valuable heavy mineral. | |
