Base Resources Limited 
Additional critical mineral product stream doubles Toliara Project's NPV 
 
Key Points 
 
 
  · Pre-feasibility study on the production of monazite has significantly 
enhanced the forecast financial returns from the Toliara Project. 
  · With an incremental NPV10 of US$1.0 billion (post-tax, real), the Monazite 
PFS has doubled the Toliara Project's overall NPV10 to US$2.0 billion (post-tax, 
real). 
  · Monazite is a rich source of rare earth elements critical to the world's 
green energy transition and represents 2.0% of the heavy mineral in the Toliara 
Project's Mineral Resources estimate. 
  · The Monazite PFS demonstrates that tails from the mineral sands processing 
planned under the Mineral Sands DFS2 can be easily upgraded to a monazite 
product, for modest additional capital expenditure. Capitalising on what is 
essentially a `waste' stream will make the Toliara Project one of the largest 
and most cost-competitive sources of rare earth oxides globally. 
  · Other key incremental outcomes from the Monazite PFS include: 
    · IRR of 79%. 
    · Capex of US$71 million and a capital payback period of 1 year. 
    · Average annual monazite production of 21.8kt, containing 2.8kt of NdPr. 
    · LOM free cash flow of US$4.7 billion, averaging US$130 million per annum. 
    · Average annual EBITDA of US$164 million. 
 
  · Key overall outcomes from incorporating the Monazite Project in the Toliara 
Project include: 
    · Average revenue to cash cost of sales ratio of 4.3 over the 38-year 
modelled mine life. 
    · Increase of LOM free cash flow by 80% to US$10.6 billion, averaging US$306 
million per annum. 
    · Average annual EBITDA of US$371 million. 
 
African mineral sands producer and developer, Base Resources Limited (ASX & AIM: 
BSE) (Base Resources) is pleased to release the outcomes of its pre-feasibility 
study on exploitation of the contained monazite at its Toliara Project in 
Madagascar through concentration of the existing waste stream from the project's 
mineral sands processing facilities to produce a valuable monazite product 
(Monazite PFS). 
 
On an incremental basis, the Monazite PFS has delivered exceptional outcomes and 
is a significant enhancement of the Toliara Project as outlined in the enhanced 
definitive feasibility study on the project's mineral sands (Mineral Sands 
DFS2).  For modest additional estimated capital expenditure of US$71million, the 
Monazite PFS outcomes include an incremental post-tax/pre-debt (real) NPV10 of 
US$1.0 billion, IRR of 79% and an average revenue to cost of sales ratio of 7.9, 
over an initial 38-year mine life.  When combined with the Mineral Sands DFS2, 
the Toliara Project has an overall post-tax/pre-debt (real) NPV10 of US$2.0 
billion. 
 
Managing Director of Base Resources, Tim Carstens, said: 
 
"Put simply, the outcomes from our Monazite PFS reinforce our belief that 
Toliara is the best undeveloped mineral sands project in the world. 
Unsurprisingly, adding another critical mineral stream through concentrating 
what would otherwise have been `waste' from the mineral sands processing has 
materially improved the forecast financial performance of the project, with a 
100% increase in NPV and free cash flow of almost US$10.6 billion over the 
initial modelled life of the project.  Utilising the waste stream as an 
essentially free source of monazite feed will make the Toliara Project one of 
the largest and most cost-competitive sources of rare earth oxides globally." 
 
"We have always believed in the Toliara Project's potential to be a catalyst for 
growth in Madagascar, creating transformational opportunities for our 
communities, economic stimulus for the Toliara region and being a flagship 
investment for the Government.  The addition of the monazite product stream 
enhances these opportunities for all stakeholders, with the project now forecast 
to generate over US$4.7 billion in direct government revenue and community 
development expenditure over the initial 38-year mine life." 
 
"With the recent conclusion of Presidential elections in Madagascar and reform 
of the mining regulatory regime well progressed, we believe that 2024 will see 
conditions supportive of the Toliara Project's progression.  We look forward to 
resuming discussions with the newly formed Government early in the new year.  We 
remain confident that acceptable fiscal terms can be secured that will support 
development of the Toliara Project, delivering clear and compelling benefits to 
our host communities, the nation of Madagascar and our shareholders."

Further information about the Monazite PFS and the PFS Materials 
 
The supporting slides attached to this release titled "Toliara Monazite Project 
Pre-Feasibility Study" form part of this release (together, this release and the 
supporting slides are the PFS Materials).  This release should be read together 
with these slides.  The information contained in the slides includes information 
in relation to the modifying factors in JORC Code Table 1, and the material 
assumptions (including in respect of the modifying factors) and underlying 
methodologies and inputs used for the Monazite PFS and from which the financial 
and production outcomes and other forward-looking statements set out in the PFS 
Materials were derived. 
 
Base Resources has concluded that it has a reasonable basis for providing the 
forward-looking statements set out in the PFS Materials.  This includes a 
reasonable basis to expect that Base Resources will, when required, be able to 
fund development of the Toliara Project, including the additional capital 
expenditure required to produce a monazite product, and obtain a legal right to 
exploit monazite2.  The Disclaimer & Important Notices on pages 2 and 3 of the 
supporting slides apply to all the PFS Materials, including this announcement. 
 
The PFS Materials also contain the outcomes from Mineral Sands DFS2 and select 
information from that study.  This information has been provided to 
contextualise the outcomes of the Monazite PFS and because the Monazite PFS was 
based on concentration of the monazite waste stream from the Mineral Sands 
DFS2.  For this reason, and to the extent material to the production and 
financial outcomes from the Monazite PFS, the assumptions and underlying 
methodologies and inputs used for the Mineral Sands DFS2 have also been included 
in the PFS Materials. 
 
For further information in relation to the Mineral Sands DFS2, refer to Base 
Resources' announcement on 27 September 2021 "DFS2 enhances scale and economics 
of the Toliara Project" available at 
https://baseresources.com.au/investors/announcements/.  Base Resources confirms 
that all the material assumptions underpinning the production information and 
forecast financial information disclosed in that announcement continue to apply 
and have not materially changed. 
 
[Note (2): The Toliara Project's existing mining tenure, Permis d'Exploitation 
37242, does not currently provide the right to exploit monazite.]
