RARE EARTHS

A STRATEGIC SOURCE OF THE  
RARE EARTH ELEMENTS DRIVING 
DECARBONISATION 

Rainbow Rare Earths (“Rainbow” or the “Company” or the “Group”) aims to be  
a forerunner in the establishment of an independent and ethical supply chain  
of the rare earth elements that are driving the green energy transition. 

It is doing this successfully via the identification and development  
of secondary rare earth deposits that can be brought into production  
quicker and at a lower cost than traditional hard rock mining projects,  
with a focus on the rare earth elements used to make permanent  
magnets, namely neodymium and praseodymium (“NdPr”),  
dysprosium (“Dy”) and terbium (“Tb”). 

Rainbow is listed on the main market of the  
London Stock Exchange under the ticker RBW.

ABOUT RARE EARTHS ELEMENTS

RARE EARTH ELEMENTS ARE FUNDAMENTAL  
TO LIFE IN THE 21ST CENTURY  

A group of 17 elements in the periodic table, including the 15 in the Lanthanide series plus  
two additional elements. Rare earths are categorised into light elements and heavy elements, 
with the latter being less common.

Classifications

Nd, Pr, Tb, Dy are critical elements of the global energy transition

Wind Turbines

Smart Phones

Speakers

Computer Drives

Defence

Due to their unique electrical and magnetic properties, rare earth 
elements (“REEs”) allow for miniaturisation and much lighter, stronger, 
resilient, and efficient components. To date, they have transformed the 
consumer electronics market, enabling the high-tech products so integral 
to our lives and which still account for ca. 50% of the rare earth market. 

However, REEs have an even more important role to play as enablers  
of the transition to the green economy. REEs are vital components of  
the type of permanent magnets used within electric vehicles and wind 
turbines, with both of these markets forecast to continue rapid growth  
as global efforts play out to reach net zero. 

Currently China controls ca. 70% of rare earth mining, but over 90% of  
the downstream rare earth processing and manufacturing. This reliance 
on one country creates supply chain vulnerability which, combined with  
a forecast deficit of supply compared with rising demand, has driven 
countries around the world to officially recognise REEs as critical minerals. 

Adding to the criticality of REEs is their growing use in high tech  
and strategic defence applications, such as guided missiles,  
drones, electronic displays, sonar and jet fighter engines.

DEVELOPMENT COMPANIES IN THE  

WORLD WITH MULTIPLE NEAR-TERM 

PRODUCTION OPPORTUNITIES”

STRATEGIC REPORT

CHAIRMAN’S STATEMENT CONTINUED

Post Year-end, the Phalaborwa project 
recorded a major milestone with the recovery 
of the first mixed rare earth sulphate from the 
front-end pilot plant in Johannesburg.  
This material is considered to be a commercially 
saleable product that could be a standalone 
revenue stream for the project, with an 
estimated sales value of ca. 60% of the global 
price for separated rare earth oxides. The 
mixed rare earth sulphate will be used as the 
feed stock to produce separated rare earth 
oxides at the back end pilot plant at K-Tech's 
facility in Florida. 

Responsible supply 
Rainbow’s business model is driven by the 
shift to cleaner energy, in that we will produce 
the materials required to make permanent 
magnets needed for EVs and wind turbines - 
with this comes a responsibility to operate  
in a sustainable manner - read more about  
our approach to sustainability on page 22.  
We have the opportunity at Phalaborwa to 
clean up legacy environmental issues on site, 
the main one being acid water which has 
accumulated over the unlined gypsum stacks. 
The acid water will be neutralised and used as 
process water, with the remnant gypsum then 
deposited on new lined stacks according  
to International Finance Corporation (“IFC”) / 
Equator Principles. This gypsum is intended  
to be further on-sold as a clean and benign 
feed for the cement and other industries, 
leaving the site rehabilitated to its original  
state over time. 

Phalaborwa’s potential to be a near-term 
source of ethical magnet rare earth supply  
was recognised by Less Common Metals Ltd 
(“LCM”), with whom we have entered into a 
strategic supply agreement for Phalaborwa 
production. LCM is currently the only rare earth 
metal and alloy manufacturing facility in the 
UK and one of the only facilities in the EU.  
Its location is of strategic importance to 
Rainbow as the Group’s aim is to play  
an important part in the establishment  
of a Western supply chain for critical REEs 
outside of Chinese control. 

Dear Shareholder, 
The world is currently in the midst of a new 
industrial revolution – the transition to a 
sustainable green energy system. This shift is 
set to drive a huge increase in the requirements 
for the minerals needed to power clean energy 
technologies. Of these minerals, REEs are 
recognised as amongst those with the highest 
risk for supply shortages, as well as displaying 
considerable supply chain vulnerability due to 
China’s dominant position in the market. 

REEs are essential components of permanent 
magnets, which are found in a plethora of high 
tech products, including smartphones, camera 
lenses, plasma screens, hard drives and even 
artificial joints. However, it is their use in electric 
vehicles (“EVs”) and wind turbines that is 
driving major future market growth, with Argus 
Media Ltd estimating that supply of the 
magnet rare earths, NdPr, Dy and Tb, will need 
to grow by ca. 8% per annum by 2032 in order 
to match demand. Read more in Market 
Review on pages 14 to 15. 

Rainbow’s aim is to be a forerunner in the 
establishment of an independent, sustainable 
and ethical supply chain of REEs and I am 
delighted to note that we made excellent 
progress towards this aim in the year to 30 
June 2023 (“FY 2023” or the “Year”) via the 
advancement of the Phalaborwa project in 
South Africa and, post Year end, via the MOU 
entered into with Mosaic to jointly develop the 
Uberaba project in Brazil. 

Both projects target secondary sources of rare 
earths, being phosphogypsum stacks that are 
the residue of phosphoric acid production. 
These stacks sit at surface, thereby eliminating 
the traditional geological risk and cost of 
mining, and are therefore expected to have a 
significantly lower capital intensity and 
operating expenditure (“opex”) than traditional 
rare earth mining projects. Furthermore they 
can be considered “near-term” production 
opportunities – for example, the Phalaborwa 
project is expected to commence operations 
in 2026, which is just five years after Rainbow 
secured the project. 

The outstanding economics of the 
Phalaborwa project were confirmed via the 
publication of its Preliminary Economic 
Assessment (“PEA”) in October last year, which 
noted a base case NPV10 of US$627 million , 
an average EBITDA operating margin of 75% 
and a payback period of less than two years. 
This very high margin sets Phalaborwa apart 
from other development projects in our space 
as it can withstand significant pricing volatility.

CHAIRMAN’S STATEMENT CONTINUED

Portfolio development 
Post Year-end, the agreement with Mosaic 
represents a major opportunity for Rainbow  
to replicate Phalaborwa at a potentially larger 
scale. The Uberaba phosphogypsum material 
is similar to Rainbow’s Phalaborwa project in 
South Africa in that the original feedstock was 
based on a hardrock carbonatite phosphate 
deposit. Initial assay analysis from samples 
have indicated an average grade of 0.58%  
total rare earth oxides (“TREO”), which is  
more than 30% higher than the 0.44% TREO  
for Phalaborwa, and confirmed that the 
Uberaba basket contains all four of the most 
economically important rare earths, NdPr  
at ca. 25% of the basket and includes the  
two “heavy” permanent magnet rare earths,  
Dy and Tb. Read more in “Uberaba” on page 20. 

Further to the acquisition of the  
Phalaborwa project in December 2020  
and the subsequent development of 
processing technology to recover REEs  
from phosphogypsum as a by-product of 
phosphoric acid production, the Directors  
have re-focused the business on secondary 
sources of REEs where they consider higher 
returns are available. As such, the Directors  
no longer intend to invest significant capital  
at the Gakara asset in Burundi to convert the 
existing resource target to a reserve status. 
This  resulted in an impairment review being 
carried out for the Gakara assets in the year 
ended 30 June 2023 and led to the net assets 
being written down to nil as at 30 June 2023. 
Read more in the “Financial Review” on page 34. 

Corporate development 
Rainbow’s successful development in FY 2023 
was rewarded by continued strong backing  
for the Company in the market, with a placing 
to raise US$9.5 million in May 2023 achieved  
at a premium of 30% to the share price,  
and a placing post Year-end in September 
2023 to raise US$5.4 million achieved at a 
minor discount of 3% to the share price. 

Both fundraisings included cornerstone 
participation by TechMet Limited (“TechMet”),  
a private investment company developing 
world class projects across the critical metals 
for the global energy transition, and which 
counts the US International Development 
Finance Corporation (“DFC”) as a major backer. 

Pursuant to the nomination right held by 
TechMet, Darryll Castle (currently Director  
of Operations for TechMet) joined the Rainbow 
Board in June 2023. Through his extensive 
career Darryll has served as an executive 
director of a number of mining and production 
companies and has first-hand operations and 
projects experience globally. We welcome 
Darryll to the Board.  

Responsible production is a core component 
of our business model and Rainbow has made 
good progress this year with setting up the 
structural aspects that will ensure ESG is 
integrated into our operations. Post Year-end, 
the Board approved a new Sustainability Policy 
for the Group and we have committed to a  
number of United Nations Sustainable 
Development Goals (“SDGs”), which will 
provide a focal point for our sustainability 
strategy and plans. Read more in Sustainability 
on pages 22 to 27. 

We have been working with carbon and 
climate change advisors to further understand 
Phalaborwa’s potential environmental impacts 
and have provided our first annual disclosure 
in line with the recommendations of the Task 
Force on Climate-related Financial Disclosures 
(“TCFD”). 

Poised for success 
I believe Rainbow offers a compelling 
investment opportunity in our space.  
Further to the MOU with Mosaic in Brazil, 
Rainbow has become one of the only rare 
earth development companies in the world 
with multiple near-term production 
opportunities, as well as occupying a unique 
position in the pipeline given our ability to 
utilise innovative and proprietary technology  
to take the processing of our material all the 
way through to separated rare earth oxides. 
Read more in “Our Business Model” on page 9. 

This is an exciting time for the Group and  
I look forward to the imminent production  
of separated rare earth oxides in Q4 calendar 
year (“CY”) 2023, bearing in mind Rainbow will 
be one of the first companies to do this on US 
soil, which further validates our vision to be an 
integral part of an independent and Western 
supply chain of rare earths. 

I would like to thank the host countries in 
which we operate and all our staff who have 
worked so diligently in laying the platform for 
delivering one of the most exciting rare earth 
stories in the world.

Q&A WITH CEO

                                “THE LONG-TERM OUTLOOK  

                       FOR RARE EARTHS IS POSITIVE AS  
                            THERE IS A MANDATED SHIFT TO THE 
                     ELECTRIFICATION OF OUR TRANSPORT  
               SYSTEM, AS WELL AS THE EXPONENTIAL  
         ROLL-OUT OF OFFSHORE WIND CAPACITY   
  TO FACILITATE GLOBAL DECARBONISATION”

WHAT DO YOU CONSIDER TO BE THE 
KEY ACHIEVEMENTS OF FY 2023? 

“

FY 2023 has been a period of further rapid 
development for Rainbow and the progression 
of our aim to be a forerunner in the 
establishment of an independent and ethical 
supply chain of the rare earth elements driving 
the green energy transition. 

The publication of the Phalaborwa PEA in 
October last year demonstrated that this was 
one of the lowest cost rare earth projects in 
development today and, not only that, it could 
be brought into production at much quicker 
pace than traditional projects, as it involves the 
processing of gypsum stacks already sitting at 
surface, thereby eliminating the cost and risk 
of mining. 

Phalaborwa will use a unique processing 
flowsheet that was developed by and in 
conjunction with our partner K-Tech and which 
incorporates continuous ion exchange (“CIX”) 
and continuous ion chromatography (“CIC”). 
While this technology was proven at lab-scale, 
we wanted to demonstrate that it is 
commercially viable and this was achieved 
both during the Year and post Year-end via the 
successful operation of our pilot plant and the 
production of the mixed rare earth sulphate. 

This validates Rainbow’s business model  
and has allowed us to target other 
phosphogypsum resources globally.  
Post Year-end, we signed an MOU with  
Mosaic in Brazil with regards to the Uberaba 
phosphogypsum stack, which is expected  
to have comparable characteristics to 
Phalaborwa due to the similarities of the host 
rock. This deal has opened up the future for 
Rainbow to become a multi-asset producer of 
rare earth elements from secondary sources. 
Read more in “Uberaba” on page 20. 

Post Year-end, we also entered into a strategic 
supply agreement with LCM, the UK-based 
world leader in the manufacture and supply  
of complex alloy systems and metals. Securing 
a buyer of our separated rare earth oxides that 
shares our values and aspirations was of 
strategic importance to Rainbow, especially as 
the vast majority of rare earth processing and 
manufacturing companies are based in China.  

The intention is for the separated rare  
earth oxides produced by Phalaborwa to  
be manufactured by LCM into metal in order  
to create an alloy, which is then supplied to 
permanent magnet manufacturers in the EU 
and the USA, with the ultimate customer of 
the rare earth permanent magnets being 
clearly defined and in alignment with the 
positioning of both Rainbow and LCM  
in a Western supply chain.

Q&A  
 
 
 
 
 
STRATEGIC REPORT

Q&A WITH CEO CONTINUED

AND WHAT WERE THE KEY  
CHALLENGES? 

“

We continued to see turbulence in the  
global geopolitical landscape, which had 
ramifications for economies worldwide, 
particularly with the ongoing disruption to 
supply chains and the rising cost of various 
inputs and commodities. This compounded 
the issue of slower global economic activity 
and growth that was already an issue further 
to the impacts of the Covid-19 pandemic. 

We have found that this has played out with 
investors taking a “risk-off” approach, 
especially with regards to smaller companies in 
the resources sector. In spite of these external, 
macro-economic challenges, we continue to 
be greatly encouraged by the progress we 
have been able to make internally and 
fortunately we have a host of catalyst points 
over the next six months to two years, as we 
deliver on the various milestones that bring 
Phalaborwa closer to first production in 2026. 

Another challenge relates to volatility in the 
pricing of rare earths experienced during the 
Year, albeit Rainbow is not in production as  
of yet. Pricing performed strongly in the year 
ended 30 June 2022 (“FY 2022”) due to 
surging demand, especially following a rush  
to install offshore wind capacity in China to 
take advantage of government subsidies, 
combined with the continued adoption  
of EVs worldwide. Pricing was also positively 
impacted by supply disruptions due to the 
COVID-19 pandemic and the start of the 
conflict between Ukraine and Russia.  
However, in FY 2023 we saw a correction in 
pricing as China increased supply, set against 
a backdrop of softer economic conditions. 

At the time of this Report, pricing has 
recovered from the lows and expectations  
are for further improvements into 2024.  

We remain confident that the long-term 
outlook for rare earth demand and pricing  
is positive as there is a mandated shift to the 
electrification of our transport system, as well 
as the exponential roll-out of offshore wind 
capacity worldwide in order to meet global 
decarbonisation and net zero targets. Read 
more in “Market Review” on pages 14 to 15.

Post Year-end, we achieved a major  
milestone with the production of the first 
mixed rare earth sulphate from Phalaborwa 
phosphogypsum material at the pilot plant 
front-end pilot plant in Johannesburg.  
This was a significant de-risking event for  
the project and the Group, as it confirms 
Phalaborwa as a rare earth producer and can 
provide a standalone revenue stream for  
the project. 

This material will be used as feed for the  
back-end pilot plant and will be processed 
further to produce separated rare earth oxides 
in Q4 CY 2023. Read more in “Phalaborwa”  
on pages 16 to 19. 

CAN YOU GIVE AN UPDATE ON THE 
PHALABORWA PROJECT?  

“

Work at Phalaborwa has continued apace  
and we are underway with all the various 
workstreams required for the Definitive 
Feasibility Study (“DFS”), which we plan  
to complete by the end of H2 CY 2024  
subject to funding.  

A major component of this was the 
construction, commissioning and operation  
of the pilot plant to prove up our proprietary 
separation technology, both at scale and  
on a continuous basis, as well as to produce 
sufficient quantities of separated permanent 
magnet rare earth oxides for testing and 
marketing purposes.  

During the Year, the decision was made to split 
the pilot plant, so that the front-end, which will 
produce a high-value mixed rare earth 
sulphate, would remain in South Africa close  
to the Phalaborwa project, while the back-end, 
which will produce separated rare earth 
oxides, would be built and run at the premises 
of our partner, K-Tech. This would deliver cost 
and time efficiencies as a result of removing 
the logistics involved in transporting pilot-scale 
equipment from the USA, where it is designed, 
fabricated, and tested, to South Africa, where it 
would have to be reassembled and 
commissioned, as well as ensuring that key  
K-Tech personnel would be available on site to 
oversee and optimise the process in real-time.

investment from the various US initiatives that 
have been set up to fund US interests in the 
green transition. We have already seen this via 
the involvement of TechMet, which has a 12% 
stake in Rainbow, and, indirectly, their major 
shareholder the DFC. 

WHAT ARE THE KEY RISKS TO ITS 
DEVELOPMENT? 

“

As the process developed with and by  
K-Tech is a novel process, albeit using  
existing technologies and equipment, 
investors undoubtedly saw technology risk  
as a key hurdle to investment. This was why 
the successful production of a mixed rare 
earth sulphate from the front-end pilot plant  
in August 2023 was an important milestone; 
however, we expect to see the benefit of a  
“de-risked” investment case once the back-
end pilot plant produces the separated rare 
earth oxides – expected in Q4 2023. 

Management has always had a high level of 
confidence in the technology. For us, it is more 
about timing of the project development and 
what could impact that. Permitting in South 
Africa is a factor, which is why we are running 
the various workstreams required already, 
alongside or incorporated with the DFS 
requirements. The fact that the project will be 
cleaning up the legacy issue of acid water on 
site I think incentivises the permitting process 
to stay on track as it is to the benefit of the 
local environment and communities. 

In terms of financing, we believe that 
Phalaborwa will continue to be of interest  
to strategic investors, especially since it will 
produce all four of the critical rare earths for 
permanent magnets, including the heavies  
Dy and Tb, which are of even scarcer supply.  
In fact, McKinsey released a report in 2023 
noting that of all the critical minerals it 
surveyed, Dy could see the most

HOW DOES THE PHALABORWA 
PROJECT COMPARE TO OTHER 
RARE EARTH DEVELOPMENT 
PROJECTS GLOBALLY? 

Phalaborwa is a unique project with 
exceptional economics, as demonstrated  
by the PEA. One of the main aspects that 
attracted me to the project was its 
comparatively low cost base, which provides 
resilience against pricing volatility: 

•

•

•

firstly, as this is not a traditional mining 
project there are no costs associated  
with drilling, blasting, crushing, milling  
and flotation to produce a mixed rare 
earth concentrate; 
secondly, the phosphogypsum material 
has already been chemically “cracked” 
because it is the by-product of phosphoric 
acid production, meaning it has already 
been subjected to heat and sulphuric acid 
– the cracked material allows for a simpler 
hydrometallurgical process to produce 
separated and purified rare earth oxides; 
and 
thirdly, the CIX / CIC separation 
technology developed by K-Tech replaces 
traditional solvent extraction (“SX”) 
technology, which uses toxic and 
flammable solvents and diluents and 
requires many different stages, thereby 
delivering a process that is safer and more 
environmentally responsible, as well as 
reduced capital and operating costs due 
to a simplified flowsheet. 

The project also has exceptional sustainability-
related opportunities as it is founded on the 
principles of circularity. We will be taking  
a waste product (the existing phosphogypsum 
stacks), cleaning it and extracting value from  
it – both via the recovery of the REEs and then 
via the sale of the benign gypsum that is 
produced as the by-product of the process. 
Our operations will see the clean-up of the 
legacy environmental issues, namely the acid 
water on site, and will fully deplete the gypsum 
stacks over time, thereby allowing for a full-
circle environmental rehabilitation of the site. 

Finally, a key benefit of targeting a secondary 
source of rare earths in this manner is that the 
project can be brought into production in a 
much quicker manner than traditional mining 
projects. In fact, we are targeting for the 
project to begin production just five years  
after we commenced work on site.

WHAT ARE THE PRIORITIES  
FOR FY 2024? 

“

The production of the separated rare earth 
oxides in the back-end pilot plant will be the 
most important milestone in the project to date 
and it is even more exciting and symbolic that 
they will be produced in the US. This favourable 
position has led us to consider permanently 
basing our oxide separation process in the  
US and we will continue to evaluate this. 

We will maintain the pace of the project 
development to date with the continued 
progress with the environmental and social 
impact assessment (“ESIA”) and publication  
of the DFS by the end of FY 2024 and that will 
set the scene to commence project finance 
and on to construction. 

We will look to gain a better understanding  
of the mineralogy of the Uberaba stack, which 
will inform the future work programme around 
resource delineation and development of a 
flowsheet adapted to the Uberaba material. 

We will continue to work with OCP and UM6P 
to evaluate the optimal technique for the 
extraction of REEs from sedimentary-sourced 
phosphogypsum. While this is a longer-term 
project, it represents an exciting opportunity 
for Rainbow due to the scale of the opportunity 
if test work can achieve favourable results, as it 
will unlock the enormous potential of rare 
earths contained in sedimentary-sourced 
phosphogypsum material. Read more in “OCP” 
on page 21. 

Finally we will also be continuing to develop  
our sustainability approach and practices 
within the Group, bearing in mind these are  
an essential part of our future success, and are 
conducting a life cycle assessment (“LCA”) at 
Phalaborwa to understand the environmental 
impacts associated with the lifecycle of rare 
earths production. 

It’s an exciting period ahead. I would like  
to thank the Rainbow team, as well as our 
various partners and contractors, for working 
tirelessly to deliver the results we have to date.

EVOLVING REGULATORY 
LANDSCAPE 

REEs are considered integral to decarbonisation, as well as having 
many highly strategic uses in advanced technologies, including in 
defence applications.  

Currently China controls ca. 70% of rare earth mining, but ca. 90% 
of the downstream rare earth processing and manufacturing. 
This reliance on one country creates supply chain vulnerability, 
which is exacerbated by geopolitical tensions. 

As such, the world has woken up to REEs as “critical minerals”,  
i.e. minerals that are considered essential to economic or national 
security and which have a supply chain vulnerable to disruption. 
The race is on to access new sources of raw material supply from 
countries outside of China aligned with Western interests, as well 
as to develop downstream processing and manufacturing 
capabilities.

MARKET REVIEW

CLEAN ENERGY IS  
DRIVING A HUGE  
INCREASE IN DEMAND  
FOR REEs 

Demand drivers  
Currently, ca. one third of global REPM demand is driven by EV 
drivetrains and wind turbines applications. The remaining ca. two thirds 
is driven by consumer electronics, traditional automotive, HVAC, disk 
drives, speakers, robotics and a variety of consumer/industrial/defence 
applications. However, growth in the clean energy sector is expected  
to see its share of the REPM market rise to ca. 56% by 2028, according  
to Canaccord Genuity and Adamas Intelligence. 

REPM demand by end-user 2016 – 2028 
100

Due to their unique electrical and magnetic properties, rare earth elements 
have become integral to many of the high tech products that we rely on 
today, especially consumer electronics such as laptops, smart phones and 
flat screen TVs, as well as being used across diverse applications such as 
lasers, glass, magnetic materials and industrial processes. 

However, the shift to a clean energy system is set to drive a huge increase 
in the requirements for REEs and other critical minerals, meaning that the 
energy sector is emerging as a major force in mineral markets. 

The four REEs that are particularly important to the green energy 
transition are Nd Pr, Dy and Tb, due to their role in the rare earth 
permanent magnets (“REPMs”) critical for use in EVs and wind turbines. 

The competitive advantage of REPMs is their very high strength to 
weight ratio, meaning they can deliver a higher power output from a 
more compact magnet size than other magnets. The most powerful 
REPM on the market currently is the neodymium magnet, also known  
as an NdFeB magnet, which is renowned for having the best magnetic 
properties, as well as being easy to process into the special shapes 
required for innovative technologies. 

REPMs are also integral to the defence industry, where they are used for 
integrated electronic displays, sonar, laser and advanced guiding systems. 

REPMs are by far the most economically important use of rare earths, 
accounting for ca. 26% by volume in 2022, but ca. 74% by value;. 
however, they are forecast to account for +99% by value by 2040, 
according to Argus Media. 

    Relevance to Rainbow: The Phalaborwa project is well placed  
to capitalise on the demand for REPMs, as its rare earth basket  
contains all four of the most important rare earths (NdPr, Dy and Tb)  
in economic quantities.

Within the clean energy space, there are two major drivers of demand  
for REPMs, being EVs and wind turbines. 

The EV market is forecast to grow ca. 13% per annum from 2023 to 2033, 
with global sales of EVs expected to rise to ca. 49 million units in 2033.

The increasing use of REPM direct drive generators (efficiency  
benefits over traditional gearbox-based designs) used in wind turbines  
is expected to be another key demand driver, as wind generation is one 
of the fastest growing forms of energy. Nearly 400GW of capacity is 
expected to be installed from 2021 to 2031, which will require growth  
of ca. 20% per annum.

MARKET REVIEW CONTINUED

Supply Outlook 
Rare earth supply grew 19% from ca. 236Kt in 2021 to ca. 280Kt in 2022, 
driven by higher output from China and Myanmar. China updates its REE 
mining and smelting/separation quotas twice a year. The production 
quota increased by 25% to 210kt TREO in 2022 and a more moderate 
increase of 14% to 230kt TREO was set for 2023. This increase was 
deemed appropriate in order to support global demand growth and in 
light of uncertainty surrounding output from Myanmar, where production 
at certain assets was temporarily shut down during the year. 

Rare earth pricing 
Rare earth pricing performed very strongly in FY 2022, with 10-year 
highs hit in Q1 2022 due to surging demand, especially following a record 
year in the roll-out of global offshore wind capacity, according to the 
Global Wind Energy Council, with a quadrupling in additions from 2020 
as a result of a rush to install offshore wind in China to take advantage  
of government subsidies, combined with the continued adoption  
of EVs worldwide. 

Pricing was also positively impacted by supply disruptions, particularly 
due to the COVID-19 pandemic and the start of the conflict between 
Ukraine and Russia. 

It has been a different picture in FY 2023, with pricing of NdPr down  
ca. 50% due to the increased supply, set against weaker demand due  
to softer economic conditions in China and globally. At the time of this 
Report, pricing has recovered from the lows and expectations are for 
further improvements into 2024.  

While there could be continued pricing volatility in the short-term, 
industry commentators agree that the longer-term outlook for REE 
pricing is supportive given the forecast supply/demand deficit that  
will be driven by global decarbonisation.

       New projects

While there are a number of new REE projects outside of China in 
development today, there are multiple challenges in bringing new supply 
to market. Due to the nature of REE mineral deposits, they often involve 
complex mineralogy with associated radioactive elements. This can lead 
to processing challenges, as well as permitting difficulties, and is 
associated with higher capital requirements and ongoing operating costs. 

    Relevance to Rainbow: The Phalaborwa project will recover REEs  

from phosphogypsum stacks that sit at surface, thereby eliminating  
the mining cost and risk associated with traditional development 
projects, as well as the longer lead time required to bring a new  
project into production. 

While REE supply is forecast to continue to grow, it is not expected  
to be able to keep pace with the fast-growing demand for REPMs, which 
would need supply of the permanent magnet REEs to grow by nearly 9% 
per annum to satisfy the demand for the green energy transition.

PRODUCTION  
EXPECTED 2026

Overview 
The Phalaborwa project in South Africa 
represents an exciting, near-term production 
opportunity of all four of the magnet rare 
earths required for the green energy transition. 

The operation will involve the processing of 
phosphogypsum stacks, which are the by-
product of historic phosphoric acid production 
on the site, which ceased in 2014. This 
resource sits at surface, thereby eliminating 
the cost and risk of traditional mining projects. 

Rainbow will be using proprietary separation 
technology developed by, and in conjunction 
with, its partner K-Tech, which will allow for the 
material to be processed into separated rare 
earth oxides of 99.95% purity. Annual 
production is estimated to be ca. 1,850 tonnes 
of the magnet rare earths NdPr, Dy and Tb. 

Apart from delivering products that are vital to 
global efforts of decarbonisation, Phalaborwa 
has strong environmental credentials in terms 
of reducing legacy risks from the previous 
operations on site to an environmentally 
sensitive area. Furthermore, consideration of 
sustainability-related risks and opportunities 
are an integral part of the Phalaborwa 
development and operating plan. 

Rainbow currently owns 85% of the project, 
with an option to acquire the remaining 15% 
from Bosveld for US$7 million of equity in the 
Company - read more on page 34. 

Background to Phalaborwa 
Phosphogypsum 
The original source rock for the phosphoric 
acid operations was a hardrock carbonatite, 
which was mined to initially produce a 
phosphate slurry feed that was then 
processed into phosphoric acid. While the 
hardrock carbonatite did not contain rare 
earths in sufficient quantities to be mined for 
these elements alone, the processing it 
underwent served to concentrate the quantity 
of rare earths contained therein, resulting in 
higher concentrations of rare earths than were 
in the original hardrock. 

This processing also subjected the material  
to sulphuric acid and heat, which effectively 
led to “cracked” chemical phosphogypsum 
material at Phalaborwa. The benefit of this is 
that it has rendered the rare earths associated 
with the phosphogypsum amenable to direct 
acid leaching, which allows for a simpler 
hydrometallurgical process to produce 
separated and purified rare earth oxides.

OPERATIONS REVIEW CONTINUED

PHALABORWA 
CONTINUED

Phalaborwa’s comparatively low operating 
cost is due to the fact that its material has 
already been mined and deposited at surface, 
which eliminates the cost and risk associated 
with traditional rare earth development 
projects. It also gives the project exceptional 
resilience against pricing volatility, which was 
experienced in FY 2023. 

The PEA generates a strong EBITDA  
at all pricing scenarios, with our sensitivity 
analysis showing that at US$60/kg for Nd and 
Pr oxides, which is below the weakest prices 
seen in 2023, Phalaborwa would produce  
US$82 million per annum EBITDA – rising to  
an average of US$504 million per annum over 
the project life using long term forecast pricing 
from Argus Media published in April 2023. 

Update on operations 
Rainbow is well progressed on a number of 
workstreams required to deliver the project’s 
DFS, which is due by the end of H1 2024.  
METC Engineering has commenced work  
to fully define the engineering scope required 
for the project and will play a central role  
in coordinating the different operational 
aspects of the DFS. Paragon Tailings has  
been engaged to advise on the work  
around reclamation of the gypsum stacks  
in accordance with strict safety and 
environmental standards, and will be assisted 
by the US-based global gypsum experts 
Ardaman and Associates, Inc., a Tetra Tech 
company (“Ardaman”). Ardaman are 
conducting tests and the design work for the 
new stacks upon which the benign gypsum 
will be deposited. 

Full ESIA workstreams are underway with WSP 
Golder for the DFS and permitting process. 

Stellar economics 
The PEA was based on processing 2.2 million 
tonnes per annum of phosphogypsum over  
a 14-year project life to deliver 26,208 tonnes 
of separated rare earth magnet oxides at an 
average cost of US$33.86/kg. This delivers an 
exceptional 75% operating margin at the base 
case basket price of US$137.92 per kg for the 
rare earth oxides. 

The base case financial model set out  
in the PEA delivered: 
•

post-tax NPV10 of US$627.4 million, 
representing more than double the 
US$295.5 million total capital cost ; 
post-tax IRR of 40%; and 
post-tax payback of upfront capital costs 
after two years of operations.

OPERATIONS REVIEW CONTINUED

A key workstream that forms part of the 
project’s DFS is the operation of a pilot plant  
in order to optimise the flowsheet and 
demonstrate the efficacy of the separation 
technology developed by and with K-Tech. 

Phase one of the pilot plant comprises  
a front end situated at the facilities of Mintek  
in Johannesburg, South Africa. The front-end 
process incorporates the front-end gypsum 
washing, acid leach, fluoride removal via CIX, 
rare earth precipitation and a sulphuric acid 
agitated bake to produce a high-value mixed 
rare earth sulphate. This was successfully 
achieved in Q3 CY 2023, with the product 
being in line with management expectations  
in terms of purity, grade, reagent consumption 
and overall recoveries of ca. 65%. 

Phase two of the pilot plant comprises  
a back end situated at the facilities of K-Tech  
in Lakeland, Florida, USA. The back-end 
process will water leach the mixed rare earth 
sulphate into a pregnant leach solution, 
perform a cerium rejection step to minimise 
flows downstream (thereby further reducing 
operating costs and capital expenditure) into 
the CIX circuit for loading onto the cation resin 
before stripping and going into the final CIC 
step, which will produce the separated rare 
earth oxides using K-Tech’s patented  
CIX/CIC technology. 

Rainbow is currently exploring the option  
of permanently establishing its back-end rare 
earth oxide separation process in the USA and 
has identified a potential site for a commercial 
scale plant. 

Mineral Resource Estimate (“MRE”) 
During the Year, the Group published an 
updated JORC compliant MRE for the project, 
which upgraded a portion of the Inferred 
Resource to Measured and Indicated and 
confirmed a total Resource of 30.4 Mt at 0.44% 
TREO, with the high-value, permanent magnet 
elements Nd and Pr representing 29% of the 
TREO in the rare earths basket, as well as 
economic quantities of Dy and Tb. The full MRE 
can be accessed at 
https://www.rainbowrareearths.com/ 
project/phalaborwa/. 

The technical team is currently focused on 
evaluation and confirmation of the bulk density 
at depth of the gypsum stacks, also with input 
from Ardaman. It is probable, based on 
Ardaman’s experience and techniques used  
to evaluate the resource of similar 
phosphogypsum stacks, that the in-situ dry 
density for the stacks below the water table  
is higher than that for the upper dry material. 
This may result in an increase in the MRE. 

Sustainability-related opportunities 
Rainbow’s operations at Phalaborwa will serve 
to clean up a legacy environmental issue – 
namely the build-up of acid water associated 
with the historic gypsum stacks, which are 
currently unlined. 

Rainbow’s front-end plant process will 
neutralise the acid water and the plant’s  
by-product will be a cleaner “benign” gypsum 
which no longer contains any acid water 
residue. The neutralised water will be used  
in the closed-circuit plant process, thereby 
eliminating the need to draw on an external 
water source. 

The benign gypsum will be deposited  
on new stacks which are lined according to 
International Finance Corporation standards 
and Equator Principles. Post Year-end, 
Rainbow signed a letter of intent to enter  
into an offtake agreement with NEXUS,  
under which NEXUS will acquire the benign 
gypsum and on-sell it to both South Africa  
and neighbouring countries. 

This agreement will see the stacks at 
Phalaborwa eventually fully depleted, allowing 
for a complete environmental rehabilitation of 
the site, as well as having a positive socio-
economic effect on local industry. 

An important part of an independent 
and ethical rare earths supply chain 
Phalaborwa is a unique project in that it offers 
a near-term source of responsible production 
of the critical rare earths NdPr, Dy and Tb,  
all of which can be delivered as separated 
oxides, unlike most projects which produce  
a mixed rare earth product. 

These credentials are demonstrated by the 
backing for Rainbow and Phalaborwa by 
TechMet, the critical minerals champion which 
is itself partially funded by the US DFC, and the 
strategic supply agreement with UK-based  
LCM, which is looking to negotiate a binding 
offtake agreement for Phalaborwa’s  
separated rare earth oxides.

THE IMPORTANCE OF HEAVY RARE 
EARTH ELEMENTS (“HREES”) 

Heavy rare earth metals are defined by 
their higher atomic weights relative to light 
rare earths. They are less common, and 
some elements within the group are facing 
shortages as demand outpaces supply. 

The incorporation of Dy and Tb into REPMs 
delivers enhanced operating performance 
by enabling them to operate at higher 
temperatures (magnets with HREE can 
operate up to 240°C as compared to 60°C 
for those magnets without HREE), without 
losing their magnetic properties (high 
coercivity). This makes them essential to 
the REPMs used in EVs, wind turbines and 
military applications. 

Of all the critical minerals, McKinsey 
assesses that Dy and Tb are amongst  
the highest risk for supply shortages  
and it was telling that China actually 
decreased its production quota for  
HREEs in H1 2023, which is considered 
likely due to resource scarcity. 

While there are some processing projects 
in the development pipeline, there are 
currently no facilities producing separated 
HREE oxides outside of Asia. 

Relevance to Rainbow: The Phalaborwa 
project will produce all four of the critical 
REPM REEs, including Dy and Tb. If the 
Group decides to establish the plant back-
end process permanently in the USA, this 
could establish Rainbow as one of the first 
producers of separated rare earth oxides 
in the country.

UBERABA 
BRAZIL

THE OPPORTUNITY TO REPLICATE  
PHALABORWA AT A POTENTIALLY  
LARGER SCALE 

Uberaba 
The Uberaba project in Brazil is the subject  
of an MOU between Rainbow and its owner 
Mosaic, which was announced post Year-end. 

The project is similar to Phalaborwa in that it 
will entail the processing of a phosphogypsum 
stack that is the by-product of phosphoric acid 
production which was originally based on a 
hard rock carbonatite. 

Mosaic’s phosphoric acid operations are 
ongoing, meaning that new phosphogypsum 
is deposited on the stacks annually. 

Due to the similarities of the feedstock, the 
Uberaba stack was expected to have a similar 
grade and rare earth element make-up as 
those of Phalaborwa and this was confirmed 
by initial assay analysis, which indicated: 
an average grade of 0.58% TREO; 
•
the basket contains all four of the magnet 
•
rare earths NdPr, Dy and Tb, with NdPr 
representing ca. 25% of the basket. 

Rainbow and its partner Mosaic are very 
encouraged by these results and are therefore 
planning additional test work at SGS 
Laboratories in Toronto around the mineralogy 
to identify the rare earth phases and facilitate 
the development of a processing test 
programme. The costs for this initial work 
programme will be shared by both parties 50:50. 

Under the terms of the MOU, Rainbow and 
Mosaic will look to jointly develop a process 
flowsheet to extract the rare earth elements 
from the Uberaba stack. Due to the similarity  
of the Phalaborwa and Uberaba projects, 
Rainbow anticipates that the majority of the 
Phalaborwa front-end process flowsheet 
(jointly developed by Rainbow and K-Tech  
to deliver a mixed rare earth sulphate) will be 
applicable, as well as the Phalaborwa back-
end process flowsheet (the patented K-Tech  
IP which uses CIX and CIC to deliver separated 
rare earth oxides), which Rainbow has 
exclusive rights to in Brazil. 

Following the production of the process 
flowsheet, Rainbow and Mosaic will collaborate 
on the production of a PEA for this opportunity 
to extract rare earths. 

“This agreement with  

Mosaic represents a major opportunity  
to become a multi-asset producer  
of rare earth elements from  

secondary sources.”

A LONGER-TERM OPPORTUNITY  
TO UNLOCK THE POTENTIAL OF RARE  
EARTHS IN SEDIMENTARY-SOURCED  
PHOSPHOGYPSUM 

Rainbow, OCP and UM6P will continue  
to jointly run a test programme aimed at 
developing an economically viable process  
to extract rare earths from sedimentary-
sourced phosphogypsum. This collaborative 
effort will evaluate possible economic process 
routes to upgrade and extract rare earths from 
the relatively low grade feedstock. 

This test programme will require a longer 
timeframe than that required for the 
Phalaborwa project, as there are more steps  
to the process that must each be shown to  
be economically viable. 

“The combined skills of OCP  

and UM6P, as well as our technical  
team and partner K-Tech, offers 
unparalleled expertise in the recovery  

of rare earths from phosphogypsum.” 

GEORGE BENNETT 
CHIEF EXECUTIVE OFFICER

OCP 
In August 2022, Rainbow entered into  
a master agreement with OCP, the Moroccan 
world-leading producer of phosphate 
products, and UM6P, a Moroccan university 
with a strong focus on science, technology 
and innovation, to further investigate and 
develop the optimal technique for the 
extraction of rare earth elements from 
sedimentary-sourced phosphogypsum. 

As at Phalaborwa and Uberaba, the OCP 
phosphogypsum material is generated  
as a by-product from their phosphoric acid 
production operations; however, it differs in 
that the original source rock is a sedimentary 
phosphate rock. Sedimentary ores are typically 
lower grade in rare earths than hardrock 
carbonatites, but they make up the bulk  
of phosphoric acid production worldwide 
(estimated at ca. 90%). Therefore, these 
sedimentary ores represent a significant,  
and as yet untapped, potential global  
resource of rare earths. 

Test results of initial upgraded samples of the 
OCP phosphogypsum material, carried out by 
SGS Laboratories in Johannesburg, indicated 
the following:  
•
•

an average grade of 0.40% TREO; and 
the OCP basket contains all four of the 
magnet rare earths, NdPr, Dy and Tb, with 
NdPr representing ca. 14.3% of the basket.

DEVELOPING A RESPONSIBLE  
SUPPLY OF CRITICAL RARE EARTHS 

Our approach to sustainability 
By focusing on the production of critical rare earths from secondary sources, integrating environmental considerations into decision making,  
taking a responsible approach to business and concentrating on stakeholder value creation, Rainbow is a crucial contributor to a responsible, 
independent rare earths supply chain that we believe will drive the global green energy transition. 

A focus on responsible production is central to our business model. We seek to minimise to the greatest extent possible any potential,  
adverse impacts of our operations as well as to maximise the Group’s ability to positively affect the economy, environment and society. 

In FY 2023, we have concentrated on advancing our sustainability strategy. We believe in the importance of a systematic approach and are laying strong 
foundations from which to embed sustainability in project development as well as to manage, measure and report on our sustainability performance.  

Key achievements

SUSTAINABILITY CONTINUED

Sustainable Development Goals  
We recognise the role that business and industry can play in advancing 
the United Nations SDGs – the blueprint to achieve a better and more 
sustainable future for all. In FY 2023, we have analysed the 169 
underlying targets of the 17 goals to identify initial areas where we 
believe Rainbow can make a clear contribution. In global terms, clearly all 
the SDGs are important (and indeed interconnected), however, we think 
a focused approach at this stage of the Group’s development will enable 
us to take proactive steps to contribute to their achievement – both by 
optimising our positive impact as well as implementing the correct 
practices to minimise any negative impact. Therefore, we have chosen 8, 
9 and 12 as our current core goals and, as our business grows, we will 
continue to assess our performance against these, as well as look to  
add additional goals over time. 

With its innovative approach to producing critical 
rare earths in an environmentally responsible 
manner from secondary sources, Rainbow aims 
to create economic value, with a focus on local 
supply chain support and job creation, thereby 
supporting growth and development.

Rainbow leverages its technological expertise, 
and that of its partners, to effectively process 
rare earths, which are an essential building block 
for permanent magnets used in critical 
sustainable infrastructure and environmentally 
sound technologies, such as wind turbines and 
EV motors. 

The Group focuses on the production  
of rare earths from secondary sources, aiming  
to integrate a circular economy approach and 
avoid some of the carbon emissions and other 
environmental impacts often associated with 
rare earths mining business models.  
By processing material from waste, Rainbow 
looks to rehabilitate historical environmental 
degradation.

Sustainability governance and management 
Sustainability is an important agenda point at Rainbow’s Board meetings 
and the Company has a Sustainability Committee. This was previously 
the Board-level Safety, Health and Environment Committee, which has 
been amended post-Year end with updated terms of reference. 

The Sustainability Committee is responsible for overseeing on behalf  
of the Board, and making recommendations to the Board, on: 
•

the Group's initiatives, including policies, compliance systems, 
monitoring processes and strategies, to manage sustainability-
related business practices and performance;  
promoting the Group's long-term success and viability by seeking 
opportunities to strengthen the Group's licence to operate, 
recognising the role Rainbow has to play in taking a responsible 
approach to managing its environmental and social impacts as  
well as prioritising ethical business practices; and 
oversight of the implementation of the Group’s sustainability 
strategy, helping to ensure that Rainbow is a responsible, resilient 
and sustainable business. 

•

•

Rainbow’s Sustainability Policy guides the Groups’s approach and sets 
out clear commitments to operating in a safe, ethical, sustainable and 
responsible way. This is approved by the Board and is available on our 
website here: https://www.rainbowrareearths.com/about/corporate-
governance/company-policies/. 

The policy covers a range of topics such as governance and ethics, 
human rights, health and safety, employment, environmental impacts 
(including, but not limited to, those related to climate change, emissions, 
pollution, water stewardship, responsible waste management, 
biodiversity), communities and our supply chain.  

It is fundamental to our business model that sustainability 
considerations are integrated into all strategic decision making. 
Sustainability risks and opportunities are considered as part of the 
Group’s overall risk management processes and frameworks.

and responsible manner. By integrating sustainable development 
considerations into corporate strategy and decision-making 
processes, we believe we can operate in a manner which  
creates long-term shared value and benefits for our  
stakeholders and reflects our core values of: 

Governance, ethics and values 
Rainbow is committed to good governance, transparency, 
accountability, effective risk management and to conducting business 
in an ethical and responsible manner. This is guided by our policies, 
including the Group Code of Conduct, which is available on our

As part of our work to advance our approach to sustainability  
and ensure the Group has the appropriate internal frameworks to 
guide this approach, we have reviewed and further developed our 
policies in FY 2023. This involved updating existing policies and also 
implementing two key new policies – our Sustainability Policy and our 
Supplier Code of Conduct.  

Rainbow has an Anti-Bribery Policy that sets out the key principles of 
ethical and responsible conduct and standards of behaviour to which 
all employees and stakeholders are expected to adhere. We also have 
a clear Whistleblowing Procedure in place, with explicit detail on how 
we process and investigate concerns- read more on page 44. 

As our business continues to grow, we will focus on further maturing 
our procedures and developing our policies to encourage effective 
corporate governance. 

Human rights 
Rainbow is aware of its responsibility to respect and protect the 
internationally recognised human rights of our people, business 
partners and, where this is within our control, the human rights  
of those within our supply chain and communities.  

We are committed to the prevention, mitigation and, where 
appropriate, remediation of any adverse human rights impacts with 
which the Group is involved. Our approach is guided by the UN Guiding 
Principles on Business and Human Rights and the UN Declaration of 
Human Rights and is contained within our Code of Conduct (as well as 
within our Supplier Code of Conduct – see “Responsible supply chain” 
on page 25). 

Health and safety  
Our primary objective is to achieve a zero-harm working environment 
and we are committed to supporting employee health.  

We prioritise the safety of our workforce and will implement  
and maintain strong health and safety management systems  
at our operations. 

Our approach to safety prioritises a commitment to identifying and 
taking appropriate action to avoid or mitigate workplace incidents, 
injuries and illnesses. We will also provide appropriate training on 
health and safety management to our workforce and promote a 
culture of responsibility for keeping ourselves and each other safe 
from harm. 

Fair employment 
Rainbow is committed to responsible and fair employment practices, 
with due consideration to diversity, wherever we operate. We look  
to provide a working environment in which everyone is treated  
with respect and dignity.  

We aim to provide training and skills development opportunities, 
contributing to an effective and engaged workforce. 

Rainbow is an equal opportunity employer and does not tolerate 
discrimination against, or harassment of, any of our employees  
on any grounds (including race, ethnicity, national origin, age, religion, 
gender, sexuality) or retaliation. Any such instances of discrimination 
are treated as serious misconduct, in line with our Code of Conduct.

Responsible supply chain 
Rainbow is committed to developing a responsible rare earths supply 
chain and, as such, we have been working during the Year to build the 
correct internal frameworks to manage this. We have put in place  
a Supplier Code of Conduct to encourage the companies within our 
supply chains also to apply the same high standards that we expect  
at Rainbow. 

Our Supplier Code of Conduct includes some of the following  
key expectations of our suppliers: 
•

the provision of safe working conditions and responsible 
employment practices, including a minimum requirement to pay 
statutory wages and to follow applicable working time legislation; 
taking adequate measures for the prevention, mitigation and, 
where appropriate, remediation of any adverse human rights; and  
environmentally responsible operating practices. 

We are aware that effective stakeholder engagement  
will be fundamental to the long-term success of Phalaborwa  
and are focused on building mutual trust and respect with our  
local communities and integrating stakeholder considerations  
into project development decisions to create long-term value  
for all our stakeholders.  

As part of the ESIA process, we will be commencing stakeholder 
consultations in FY 2024. The Group has a Whistleblowing Policy 
which can be used by local communities to raise any concerns  
ahead of the development of a specific grievance mechanism  
for Phalaborwa which will be developed at this time.  

Following the development of our Supplier Code of Conduct, going 
forward when working with suppliers for the first time, Rainbow will 
supply them with the Code and ask them to confirm that they have 
read, understood and will comply with the commitments. We expect 
suppliers to implement or develop appropriate internal processes 
and/or corrective actions to achieve compliance with the Supplier 
Code of Conduct. 

In the event of failure to uphold commitments and in the case  
of a serious breach of practices, Rainbow may end a contractual 
relationship. 

As our business grows, responsible supply chain management  
will continue to be an area of significant focus and we will develop  
our policy and approach accordingly.

    Kicking off LCA for Phalaborwa  

By focusing on the production of rare earths from secondary sources, 
Rainbow aims to integrate a circular economy approach into business 
decisions, where possible, and avoid some of the carbon emissions and 
other environmental impacts usually associated with many elements  
of a traditional mining business model, which are not required when 
processing secondary source material as opposed to mining primary ore. 

•

Using our unique processing technology, our intention at Phalaborwa is 
to process material from historical waste in the form of phosphogypsum 
stacks in an efficient and responsible way, operating on a brownfield site 
therefore not impacting land use. We believe this will provide us with the 
opportunity to rehabilitate environmental degradation brought about by 
previous operations on site. Rainbow will work closely with previous 
owners of the property to accelerate the rehabilitation of unused areas  
in accordance with the closure plans and funding already in place. 

An important element of Rainbow’s opportunity to rehabilitate the site 
will be neutralising the acidic solution currently on top of the gypsum 
stacks for use in a closed circuit in the processing plant. In addition  
to this, Rainbow will then dispose clean, benign gypsum on stacks, 
which are built according to IFC Performance Standards and Equator 
Principles. Where possible, the Group will seek to identify uses  
for waste and by-products of its processing activities.  

Demonstrating our focus on the circular economy approach  
and the responsible use of natural resources, Rainbow has  
signed an offtake agreement with NEXUS to acquire the  
benign gypsum from Phalaborwa.  

Rainbow expects Phalaborwa to use a lower amount of energy  
and reagents (due to the material already having been “cracked”) 
when compared to traditional hard rock mining deposits. In order  
to better understand Phalaborwa’s environmental impact, we are 
conducting a LCA.  

The LCA will quantify and analyse the GHG emissions associated  
with the entire life cycle of rare earth elements production, including 
mining, processing, manufacturing, product use, and disposal.  
This will assist us in identifying opportunities for reduction to minimise 
the Group’s carbon footprint by optimising energy use, improving 
efficiency and exploring alternative materials and processes.

INTEGRATING ENVIRONMENTAL  
CONSIDERATIONS INTO STRATEGIC  
DECISION-MAKING 

Related SDGs

TCFD report 
Rainbow is focused on achieving responsible, near-term and efficient 
rare earths production from secondary sources. With demand for the 
rare earths required in permanent magnets largely driven by global 
decarbonisation efforts, Rainbow’s business model itself is linked  
to climate-related opportunities. As such, we acknowledge the 
importance of integrating climate-related risks and opportunities  
into our strategy and have initiated the first phase of carbon disclosure 
in our annual reporting, representing a significant step forward in our 
sustainability workstreams. 

We are committed to embedding environmental considerations  
into Phalaborwa’s development and are therefore intent on putting  
the right foundations in place from the outset from which to build our 
sustainability strategy. Developing climate change-related strategies 
and commitments is a key element of this approach. Rainbow’s 
climate-related reporting will mature as we move through project 
development and construction and into production. We intend  
to publish a standalone disclosure report in line with the 
recommendations of the TCFD in due course. 

In preparation for such a disclosure, we have published  
information on pages 28 to 33, which is presented according  
to the TCFD key themes and recommendations for the period  
1 July 2022 to 30 June 2023.

Phalaborwa ESIA work progressing 

We are committed to integrating environmental considerations  
into strategic decision-making at the highest level of the business  
(i.e. Board and Sustainability Committee level) in order to create  
a responsible and sustainable supply of critical rare earths. We aim  
to achieve continuous improvement in environmental practices  
and performance and to minimise, or where possible avoid, negative 
impacts from our operations on the natural environment, including 
those relating to climate change (see our TCFD Report for more 
information), water usage, waste management and biodiversity. 

The ESIA at Phalaborwa is being conducted by consultants WSP  
in accordance with IFC Performance Standards and work is 
progressing well, with many of the reports and specialist studies 
required for regulatory processes and to obtain environmental 
authorisations either at an advanced stage or in progress.  
This work will inform the implementation of a robust  
environmental management system for the project.  

As Phalaborwa progresses to development, our aim will be to 
implement sound environmental management practices around 
resource use, energy, water and waste management, air quality and 
carbon emissions and biodiversity. Given the site’s brownfield nature, 
we will look to maximise our potential for positive impacts through 
rehabilitation and remediation. 

Phalaborwa is founded on the principles of circularity via the  
extraction of value from ‘waste’ products. As part of this, the intention 
to sell the benign gypsum by-product produced at the project is 
expected to see the phosphogypsum stacks at Phalaborwa eventually 
fully depleted, which would allow for a complete environmental 
rehabilitation of the site. 

We have made significant progress in understanding Phalaborwa’s 
potential environmental impacts through the carbon accounting work 
we have commenced in FY 2023 which will feed into the LCA.

TCFD FRAMEWORK

The TCFD was created by the Financial Stability Board in 2015 to develop guidance for consistent climate-related financial risk disclosures  
for use by companies, banks, and investors in providing information to stakeholders. One of the Financial Stability Board’s key aims was to  
enable stakeholders to better understand the “concentrations of carbon-related assets in the financial sector and the financial system’s  
exposure to climate-related risks”1. 

Ultimately, increasing the amount of reliable information on exposure to climate-related risks and opportunities will strengthen the stability  
of the global financial system, contribute to a greater understanding of climate risks, and facilitate financing the transition to a more stable  
and sustainable economy. 

Accordingly, the TCFD developed a set of recommendations in 2017 to assist companies in identifying and disclosing the financial impacts  
of climate change risks and opportunities on their business in their mainstream reports, including their annual reports and financial filings.  
The latest TCFD guidance on implementing the recommendations was published in 2021, which includes supplemental guidance for  
insurance companies and asset owners. 

The TCFD recommendations are categorised according to four thematic areas that represent core elements of how organisations operate: 
Governance, Strategy, Risk Management and Metrics and Targets. These elements are outlined in Figure 1 below.

TCFD REPORT

The following table provides a summary of Rainbow’s first climate disclosures aligned with the TCFD recommendations associated with the four 
thematic areas: Governance, Strategy, Risk Management and Metrics and Targets.

GOVERNANCE

Recommendation 

Response 

a.  Describe the board’s 
oversight of climate-
related risks and 
opportunities 

Rainbow’s Board comprises the Chairman, one executive director, and five 
independent non-executive directors. The Board is responsible for regularly 
assessing and reviewing key business risks in the Group’s operations and met 
eight times in the last financial year.  

Compliance 

Partially compliant  

Notably, in the last year the Board has overseen and approved the development  
of the Group’s Sustainability Policy, which can be found on our website here: 
https://www.rainbowrareearths.com/about/corporate-governance/company-
policies/. The policy states our commitment to sound environmental 
management and minimising the impacts of our operations on the environment, 
including those relating to climate change, water usage, waste management  
and biodiversity. 

b.  Describe 

management’s role in 
assessing and 
managing climate-
related risks and 
opportunities 

The Board delegates sustainability-related responsibilities to management. 
Accordingly, the Directors and management regularly assess and discuss the 
principal risks facing the Group. In addition, senior management regularly discuss 
material developments (normally weekly) and consider the financial and reporting 
implications of any matters arising. 

Partially compliant 

A key element of risk within Rainbow’s operations is environmental management, 
which is overseen by the Board and Audit Committee, in liaison with the 
Sustainability Committee (formerly the Safety, Health, and Environment Committee).  

The Sustainability Committee has oversight of the Group’s compliance  
with applicable environmental laws and regulations. Rainbow is currently working 
with WSP to carry out an ESIA at Phalaborwa. The Sustainability Committee met 
once during the 2023 financial year to discuss the discuss the development  
of the Group’s ESG strategy, both over the short-and longer-term and  
regulatory developments.

STRATEGY

Recommendation 

Response 

a.  Describe the climate-
related risks and 
opportunities the 
organisation has 
identified over the 
short, medium, and 
long term. 

Rainbow’s strategy is to develop a responsible supply of rare earth minerals  
to meet the escalating demand for these critical minerals needed for global 
decarbonisation.  

Phalaborwa is still in the preliminary stages of development; however, in order  
to build strong foundations at the earliest stage, the following key workstreams 
have been initiated to assess and help inform a robust view of the physical and 
transitional climate-related risks and opportunities that may impact our  
operations and the environment. 

Compliance 

Partially compliant 

b.  Describe the impact 
of climate-related 
risks and 
opportunities on the 
organisation’s 
businesses, strategy, 
and financial 
planning. 

• We are in the process of quantifying and assessing expected operation 
emissions based on the PEA at Phalaborwa. This is the starting point  
from which Rainbow will measure the actual performance of the Group’s 
Greenhouse Gas (“GHG”) emitting activities once in production. 

• We are commencing work with external consultants to develop a LCA for 
Phalaborwa to assess the GHG emissions associated with producing and 
using rare earth metals. This will enable Rainbow to identify emission hotspots 
and opportunities for reduction, supporting the development of the Group’s 
decarbonisation strategy.  

• We have embarked on developing scenario analyses to evaluate future 

climate change-related risks and opportunities for the business over the 
short, medium and long term. 

Climate-related opportunities are some of the material drivers behind our 
business model and growth strategy. Rainbow is contributing to the green energy 
transition with the responsible production of rare earths, with a specific focus on 
neodymium (Nd), praseodymium (Pr), dysprosium (Dy), and terbium (Tb).  
These metals are fundamental in the production of permanent magnets used  
in wind turbines and EVs, with their demand projected to escalate with the 
transition to renewable energy - read more in Market Review on pages 14 to 15.  

The financial impacts of the climate risks and opportunities facing the business 
will be further explored and articulated following results from the LCA and 
scenario analysis testing (as described above). These measures will inform 
Rainbow’s business, strategy, and financial planning in relation to climate-related 
risks and opportunities.  

Rainbow is committed to integrating environmental considerations into  
strategic decision-making and sound environmental management, with  
a focus on environmental protection and the responsible use of natural  
resources. This includes a focus on energy efficiency and the investigation  
of the commercial viability of using renewable energy sources.

Recommendation 

Response 

c.  Describe the 

resilience of the 
organisation’s 
strategy, taking into 
consideration 
different climate-
related scenarios, 
including a 2°C or 
lower scenario.

Rainbow’s focus on processing separated rare earth oxides from historical waste 
gypsum contributes to the underlying strength and resilience of our business 
model, as many of the costly, energy-intensive steps, associated with traditional 
rare earths mining projects, are removed. Further, Rainbow has the opportunity  
to reduce its negative environmental impact by utilising reclaimed acid water  
from the phosphogypsum stacks in a closed circuit.  

Leveraging our proprietary technology, we continue to explore opportunities  
to deliver separated rare earth oxides from secondary phosphogypsum sources 
around the world, which will remove significant time, risk and cost from the overall 
project timeline. Rainbow announced a Memorandum of Understanding with 
Mosaic shortly after Year-end to jointly develop a process flowsheet to extract  
rare earth elements from the Uberaba stack in Brazil - read more on page 20. 

In addition, Rainbow intends to use climate change scenario analyses  
to fully investigate the resilience of the Group’s strategy to climate change  
risks and opportunities. The outcomes of these assessments will be published 
once available. 

The setting of a baseline carbon footprint in the future will assist us in managing 
the performance of meeting emission reduction targets and other related 
sustainability metrics.

RISK MANAGEMENT

Recommendation 

Response 

a.  Describe the 

organisation’s 
processes for 
identifying and 
assessing climate-
related risks; 

b.  Describe the 

organisation’s 
processes for 
managing climate-
related risks, and  

c.  Describe how 
processes for 
identifying, 
assessing, and 
managing climate-
related risks are 
integrated into the 
organisation’s overall 
risk management.

Rainbow is in the process of estimating and assessing expected emissions from 
planned operations at Phalaborwa based on projections in the PEA, as a first-pass 
carbon footprint assessment. Alongside the LCA and proposed scenario analysis 
workstreams, the first-pass carbon footprint will be critical in identifying and 
assessing climate-related risks and identifying carbon reduction opportunities. 
The emissions calculations will assist Rainbow in informing, understanding,  
and optimising project development and subsequent operations. 

The relatively small size of Rainbow’s management and finance team allows  
the team to retain tight control over the identification and management of risks, 
and related financial impacts, currently facing the business. The Board therefore 
does not currently consider it appropriate to have a separate internal audit 
function. Accordingly, the Board and the Audit Committee are responsible  
for ensuring that the risks inherent to operating the Group, across numerous 
jurisdictions, are identified, assessed, and managed. Rainbow’s Sustainability 
Committee is also responsible for liaising with the Audit Committee, as 
appropriate, on matters relevant to the Group’s management of sustainability-
related risks and opportunities. In addition to formal Audit Committee meetings, 
the Chief Financial Officer has regular interaction with the Chairman of the Audit 
Committee to discuss control and reporting matters in more detail. The Audit 
Committee and Chief Financial Officer are supported by senior management,  
who regularly discuss material developments (normally weekly) and consider 
financial and reporting implications of any matters arising. 

As the Group matures, Rainbow may consider formalising the processes  
for identifying, assessing, and managing climate-specific risks, which may  
be integrated into the organisation’s overall risk management. 

Using the outcomes of the ESIA, which is currently being undertaken  
for Phalaborwa, Rainbow will introduce a robust environmental and  
social management system to the project.

Recommendation 

Response 

Compliance 

Partially compliant 

The first-pass carbon footprint will assist in selecting appropriate metrics for 
monitoring our operation’s emissions. Importantly, the first-pass carbon footprint 
will be critical in identifying carbon reduction opportunities and will assist Rainbow 
in informing and optimising project development and subsequent operations. 

As a first step in our emissions accounting and disclosure, we have calculated 
Scope 1 and 2 emissions for office-related activities – demonstrating a step 
forward in transparency and setting the Group on the right path for future 
disclosure of more material operations emissions going forward. 

Rainbow’s carbon footprint for our head office emissions is shown below.  
This represents Rainbow’s actual emissions and first phase of annual carbon 
disclosure.

Scope 1                                                                                                                                       0.15 
Scope 2                                                                                                                                      5.85 
Scopes 1 & 2                                                                                                                              6.01 

The office activity-related carbon footprint does not serve as a baseline for 
benchmarking against operation-related emissions in future, as the Group’s 
material carbon emissions will be associated with its processing activities when 
production commences. Rainbow will establish a baseline emissions profile once 
the operations are in progress. 

As the Group matures, Rainbow will consider setting targets to manage climate-
related risks and opportunities. These targets will be informed by the culmination 
of ongoing climate-related scenario analyses and the setting of a baseline carbon 
footprint once the business is fully operating.

FINANCIAL REVIEW

RAINBOW’S STRATEGIC FOCUS  
IS TO IDENTIFY AND DEVELOP  
SECONDARY RARE EARTH  
DEPOSITS 

Rainbow’s strategic focus is to identify and develop secondary rare earth deposits that can be brought into production quicker and at a lower cost  
than traditional hard rock mining projects. As a developer, Rainbow capitalises the costs of exploration and evaluation for each identifiable project  
once the legal right to the project has been secured. During the Year, as a result of the successful PEA released for Phalaborwa and the growing 
pipeline of growth opportunities from the associated processing technology, the Directors decided against investing significant amounts in Burundi  
to develop a formal mineral resource. As a result an impairment review was carried out on the Gakara cash generating unit, which has been written 
down to a net asset value of nil. As a result, the Financial Statements now reflect the updated business strategy, with the exploration and evaluation 
assets on the balance sheet relating solely to Phalaborwa and the income statement dominated by the impairment charge against Gakara.

PROFIT AND LOSS 

BALANCE SHEET 

The loss for the Year reflects the impairment of the Gakara cash 
generating unit and the ongoing administrative costs for the Group. 

As noted above, due to the change in strategy an impairment review 
was carried out for the Gakara cash generating unit during the Year, 
which comprised both intangible and tangible fixed assets together  
with cash, mineral concentrate, royalty receivables and consumables 
held in stock. The liabilities associated with the Gakara project include  
a loan, decommissioning, site rehabilitation and environmental costs, tax 
liabilities and trade payables. Based on the assessment of both the legal 
and political position in Burundi, the Directors were unable to foresee a 
date when the operations at the project would be able to restart and 
accordingly have written the net assets of the Gakara cash generating 
unit to nil, with an impairment charge of US$9.6 million recognised. 

Within administration expenses, the costs associated with maintaining 
the Gakara project on care and maintenance totalled US$0.9 million (FY 
2022: US$1.3 million) including US$0.3 million of non-cash depreciation 
associated with the tangible fixed assets prior to the impairment (FY 
2022: U$0.4 million). The Group continues to focus on minimising costs 
associated with the asset. 

The Group’s other corporate costs totalled US$2.6 million (FY2022: 
US$2.3 million). This increase was driven primarily by an increase  
in business development costs as the Group started to develop its 
pipeline of growth opportunities including both Uberaba and OCP. 

Net finance income of US$0.2 million (FY 2022: costs of US$0.3 million) 
represents foreign exchange differences, primarily relating to movements 
between the Burundian Franc (“BIF”) and US dollars, the functional 
currency of the Group. Finance costs also include US$0.1 million (FY 2022: 
US$0.1 million) associated with the FinBank loan in Burundi. 

34 Rainbow Rare Earths Limited 

Annual Report & Financial Statements 2023

As set out above, the Gakara impairment has had a significant impact  
on the Group balance sheet, with US$9.8 million of non-current assets 
at 30 June 2022 relating to Gakara (US$8.6 million of exploration and 
evaluation costs and tangible fixed assets with a net book value of 
US$1.0 million) being written down to nil. The Gakara cash generating 
unit now includes US$0.7 million of mineral concentrate inventory, 
carried at cost, which is offset by the FinBank loan (US$0.4 million)  
and other net liabilities of US$0.3 million dominated by tax and 
government liabilities in Burundi which have not been settled whilst  
the suspension of activities persists. 

A total of US$2.9 million of exploration and evaluation assets were 
capitalised in the Year relating to Phalaborwa, leaving a closing 
capitalised cost of US$4.8 million. Expenditure accelerated following 
completion of the PEA in October 2022 as pilot test work commenced 
alongside other activities to develop a DFS. At the balance sheet date, 
the Group has no tangible fixed assets and no obligations for 
environmental closure at the Phalaborwa site. 

At 30 June 2023, the Group held US$8.1 million of cash and cash 
equivalents which is predominantly held with Barclays Bank in London, 
having raised US$9.5 million in May 2023 at a price of 10.377 pence  
per share. 

GOING CONCERN 

In July 2023, US$5 million was paid to Barak Fund SPC Limited on behalf 
of Bosveld Phosphates (Pty) Limited to secure a path to 100% ownership 
of Phalaborwa. As a result of the payment, the Group secured an 
immediate 85% interest in Phalaborwa and was granted an option to 
acquire the remaining 15% via the issue of US$7 million in shares. In 
September 2023, the Company replenished the funds spent on the 
Phalaborwa acquisition, raising US$5.5 million at a price of 15 pence per 
share, of which US$0.7 million is subject to shareholder approval at the 
forthcoming AGM. 

Based on a review of cash flow forecasts for the period to 31 December 
2024, at least US$3.4 million of additional funding will need to be raised 
before 31 December 2024, the timing of which is dependent primarily on 
the speed at which the Phalaborwa DFS is completed, which is within 
management’s control. Whilst this funding requirement does represent a 
material uncertainty which may cast significant doubt on the ability of the 
Company to continue as a going concern, the Board is confident that this 
funding will be secured based on its history of successful fundraising.

CORPORATE GOVERNANCE  
STATEMENT

As a guernsey-registered company, trading on the standard list  
of the main market of the London Stock Exchange, the UK Corporate 
Governance Code published by the Financial Reporting Council does not 
apply to the Company. However, the Directors recognise the importance 
of effective corporate governance and have implemented corporate 
governance practices having consideration to the recommendations 
and principles of the UK Corporate Governance Code as far as is 
appropriate bearing in mind the size and nature of the Company. 

The Board oversees the performance of the Group’s activities. It 
comprises experienced board members who have held senior positions 
in a number of public and private companies. The Board is responsible  
to shareholders for the proper management of the Group. The Non-
Executive Directors have particular responsibility to ensure that the 
strategies proposed by the Executive Director are carefully considered. 
The Board meets regularly and met eight times in FY 2023. Prior to such 
meetings taking place, an agenda and board papers are circulated to the 
Directors so that they are adequately prepared for the meetings. 

To enable the Board to discharge its duties, all Directors have  
full and timely access to all relevant information. 

There is no agreed formal procedure for the Board (or members thereof) 
to seek independent professional advice but, pursuant to their letters of 
appointment, the Non-Executive Directors may, where appropriate, take 
independent professional advice at the Group’s expense. 

In accordance with the Company’s articles of associations, the Directors 
submit themselves for re-election every three years at the Company’s 
annual general meeting (“AGM”). 

The composition of the Board will be reviewed regularly to ensure  
that the Board has the appropriate mix of expertise and experience.  
The articles provide that the number of Directors that may be appointed 
may not be fewer than two. Two Directors present at a board meeting 
constitutes a quorum. 

The Board ensures it is aware of the views of major and other 
shareholders through regular meetings in person (where appropriate), 
feedback via the Company’s investor relations manager or via the review 
of investor relations board reports, as well as through discussions with 
the Company’s brokers and market analysts. Where such information 
has been obtained by the CEO, this information is disseminated to the 
rest of the Board in a timely manner. 

Review of internal control and risk management systems 
The Board has reviewed the Group’s internal control and risk 
management systems. 

Rainbow has a relatively small team of management and financial staff 
and is therefore able to retain a tight control over its financial reporting 
activities. The Board does not consider it appropriate to have a separate 
internal audit function, however a number of internal controls and 
reviews have been put in place to provide the Board (and the audit 
committee) with assurance that the risks inherent to operating a natural 
resource company in more than one jurisdiction are managed 
appropriately.  

These controls include the following: 
•

Budgets and forecasts are prepared by finance staff in conjunction 
with operating teams and are reviewed and approved by senior 
management (and in the case of the budget, by the Board). 
Actual results are reported against budget and forecast, and 
variances examined. 
All banking transactions must be initiated and authorised by at least 
two staff members, one of whom is a senior manager (CEO or CFO). 
Since the retirement of the general manager in Burundi, all payments 
are approved by the CEO or CFO prior to payment being made locally. 
For international payments, all payments are approved in the online 
banking system by the CFO following sign-off by the CEO. 
Financial operations in Burundi are reviewed regularly by the CFO, 
both on visits to Burundi and online. During the FY 2023, reviews 
were primarily conducted in an online environment and in-country 
visits limited to discussions with the Burundi government. 
The Group uses a central financial reporting system (xero) which 
records all transactions, capturing third party documents (e.g. 
invoices) which are reviewed by head office on a monthly basis. 
Senior management regularly discuss material developments 
(normally weekly) and consider financial and reporting implications 
of any matters arising. 

•

•

•

•

•

In addition to formal audit committee meetings, the CFO has regular 
interaction with the audit committee chairman to discuss control and 
reporting matters in more detail.

STATEMENT CONTINUED

Board of Directors 
The Company had one Executive Director and six Non-Executive Directors at 30 June 2023. All major decisions relating to the Group are made  
by the Board as a whole. Operations are conducted by the subsidiaries of the Company. In Burundi, the Company is represented on the Board  
of Rainbow Mining Burundi SM by the CEO and CFO. 

The Board reviews key business risks regularly, including the financial risks facing the Group in the operation of its business.  
These matters include, but are not limited to, the following: 
determining the strategy for the Company; 
•
approving the annual budget; 
•
discussing and approving financing, including new debt and equity; 
•
setting the dividend policy; 
•
•
developing the appropriate ESG standards and practices; 
• mergers and acquisitions activity and significant transactions;

are considered to be independent (with the exception of Darryll Castle) in terms of character and judgment, notwithstanding the following: 
•
•

all the independent Non-Executives are shareholders in the Company see Board of Directors on pages 38 to 39 for further information). 
all the independent Non-Executives held share options during the Year (see note 22 for details). 

Darryll Castle is not independent because he is the Director of Operations for TechMet, a strategic shareholder with the right to nominate one Director 
to the Rainbow Board for so long as it holds at least 10% of the issued shares in the Company.

The table of board committee attendance is based on the board committee appointments at the time of the relevant meeting. The Board is regularly 
informed of developments outside of formal board meetings, through update calls and meetings, reports and one-to-one discussions with the CEO 
and other management. 

The deliberations of the various committees, referred to on page 44, do not reduce the individual and collective responsibilities of board members  
with regard to their fiduciary duties and responsibilities, and they must continue to exercise due care and judgment in accordance with their  
statutory obligations. 

These terms of reference are subject to the provisions of the articles and any other applicable law or regulatory provision in force in Guernsey,  
and the listings rules. 

In addition to the audit, remuneration, nomination and SHEC (now renamed the Sustainability Committee) committees which have formally delegated 
duties and responsibilities within written terms of reference, the Board may set up additional committees as appropriate.

STATEMENT CONTINUED

Diversity 
The Board of Rainbow understands that diversity and inclusion are important in providing a broad range of perspectives in the workplace,  
fostering innovation, encouraging collaboration and enabling businesses to deliver better results for their stakeholders. 

As the Company progresses on its development path, it will continue to consider the appropriate mix of skills, culture and qualities,  
as well as the diversity represented, that will allow Rainbow to deliver on its strategy.  

Rainbow is committed to developing a diverse workforce and to providing a work environment in which everyone is treated fairly and with respect. 

The Company does not currently have a formal Board diversity policy which is mainly a reflection of the small size of the Rainbow business to date. 
However, as part of its future development plans, in FY 2024 the Company aims to commence the planning work required to put a diversity and 
inclusion policy in place that will set out its commitment to ensuring an equitable, diverse and inclusive workplace. 

As part of this work, we will be looking at all elements of diversity and considering a broad definition of difference, including but not limited to: 
experience, skills, expertise, ethnicity, nationality, gender, cultural and socio-economic background, geographic location, age, education, religious 
beliefs, language, neurodiversity, disability, sexuality and family responsibilities.

Gender diversity 
The Company has not met the UK’s Financial Conduct Authority’s (“FCA”) diversity targets that at least 40% of the board members should be female 
and that at least one of the senior board positions should be held by a woman, and the reason for this mainly relates to the historically lower proportion 
of women in the resources and industrial industries. However, the Company is aware that much progress has been made in order to increase female 
representation in these sectors and will be looking to improve its gender diversity statistics as the Company continues with its corporate development 
path. This will be a focus for the Company’s Nomination Committee in FY 2024.

CORPORATE GOVERNANCE  
STATEMENT CONTINUED

Audit committee 
The Board has established an audit committee with formally delegated 
duties and responsibilities. The audit committee is chaired by Atul Bali 
and its members are Alexander Lowrie and Shawn McCormick.  
The members of the audit committee are considered to possess the 
appropriate skills and experience to monitor and ensure the integrity  
of the Group’s financial reporting, Internal Audit, internal financial control 
and risk management systems and to support Rainbow’s governance. 

The audit committee should meet not less than two times a year  
and is responsible for ensuring the financial performance of the Group  
is properly reported on and monitored, including reviews of the annual 
and interim accounts, results announcements, internal control systems 
and procedures and accounting policies. It is also responsible for keeping 
the categorisation, monitoring and overall effectiveness of the Group’s 
risk assessment and internal control processes under review. 

The audit committee met three times during the Year. During these 
meetings, the following matters were considered: 
•

the audit of the year ended 30 June 2022 was planned and the  
key areas of audit risk were discussed ahead of the relevant audit 
procedures being undertaken. The audit planning meeting for FY 
2023 occurred after the financial year end. 
the financial statements for the year ended 30 June 2022, and the 
interim financial statements for the six months ended 31 December 
2022, were reviewed. The audit committee met with the auditors at 
the conclusion of the FY 2022 audit to discuss their findings and, 
following due consideration, recommended to the Board that these 
financial statements be approved. 

•

The audit committee also considered the conduct of the external audit 
by BDO LLP, which was considered to be appropriate. The committee 
therefore resolved to propose BDO LLP for reappointment at the next 
AGM for a period of 12 months. It was noted that BDO LLP had been 
auditors of the Company since October 2016. 

The audit committee also considered the independence and objectivity 
of BDO LLP. The committee considered the composition of the BDO 
audit team, together with the duration of service of the partner and 
senior audit team members on the Group’s audit and concluded that 
BDO LLP was sufficiently independent to conduct the audit. The only 
non-audit service during the Year was the informal review of the interim 
financial statements for the six months to 31 December 2022. 

Nomination committee  
The nomination committee is chaired by Adonis Pouroulis and its 
members are Atul Bali and J. Peter Pham. The nomination committee is 
normally expected to meet only as required. The nomination committee 
is responsible for reviewing, within the agreed terms of reference, the 
structure, size, and composition of the Board, undertaking succession 
planning, leading the process for new Board appointments, and making 
recommendations to the Board on all new appointments and re-
appointments of existing Directors. The nomination committee did not 
meet during FY 2023. 

Remuneration committee 
The remuneration committee is chaired by Alexander Lowrie and its 
members are Adonis Pouroulis and Shawn McCormick. It is expected to 
meet at least once a year. The remuneration committee has responsibility 
for determining, within agreed terms of reference, the Group’s policy  
on the remuneration of senior executives and specific remuneration 
packages for Executive Directors and the Non-Executive Chairman. The 
remuneration of Non-Executive Directors is a matter for the Board. No 
Director may be involved in any discussions as to their own remuneration. 

Safety, health, and environment committee  
The SHEC is chaired by Shawn Mccormick and its members  
are George Bennett and Alexander Lowrie. 

The SHEC is responsible for developing and reviewing the Group’s 
framework, policies and guidelines on safety, health and environmental 
management, monitoring key indicators on accidents and incidents 
within the Group’s operations and considering developments in relevant 
safety, health and environmental practices and regulations. 

The SHEC met once during FY 2023 to discuss the development  
of the Group’s sustainability strategy, both over the short-and longer-
term, and an action plan and budget were subsequently approved in 
order to deliver on this strategy. Post year-end, the SHEC was renamed 
the Sustainability Committee - see page 23 for details.  

Share dealing policy 
The Company has a share dealing policy requiring all Directors  
and Senior Executives to obtain prior written clearance from either  
the Chairman or the Chief Executive Officer to deal in linked shares.  
The Chairman requires prior written clearance from the chairman of the 
audit committee. Close periods (as defined in the share dealing policy) 
are observed as required by market abuse regulations and other rules 
that apply to the Company by virtue of the market on which its shares 
are listed. During these periods, the Company's Directors, Senior 
Managers and inside employees are not permitted to deal in the 
Company’s securities. Additional close periods are enforced when  
the Company or its applicable employees are in possession  
of inside information. 

Anti-bribery policy 
As part of our work during the Year to strengthen our policies,  
we have updated the Group’s Anti-bribery Policy. The Policy includes 
clear guidance on expected behaviour and procedures (including 
whistleblowing), which apply to the Group, its officers and staff 
anywhere in the world. The Policy and procedures have been developed 
following an assessment of the risks applicable to the Group’s business 
and include clear definitions as well as a process for reporting suspicious 
conduct, financial limits on gifts and hospitality, procedures for financial 
record-keeping and for dealing with contracts with third parties, and a 
prohibition on charitable or political donations without Board approval. 
Guidance and expectations around conflicts of interest are included in 
the Group’s Code of Conduct. 

Pete Gardner, CFO, acts as the Group’s Anti-bribery Officer, overseeng 
the day-to-day operation of the Policy and procedures. He reports  
to the Board on any specific issues that might arise and the Board also 
regularly reviews the operation of the Policy and related procedures. 

All personnel are required to receive guidance and training in relation  
to the Group’s Policy and procedures.

PRINCIPAL RISKS AND  
UNCERTAINTIES

The Directors regularly assess and discuss the principal risks facing the Group, including those that would threaten its business model, 
future performance, solvency or liquidity. 

The key risks affecting the Group are set out below: 

Risk 

Comment 

Business impact 

Mitigation 

Project definition 
risk

At Phalaborwa, PEA published in October 
2022 confirmed a processing flowsheet 
capable of economically extracting the 
magnet rare earth metals from the gypsum 
stacks in a low capital and low operating cost 
environment. 

High

Pilot test work to confirm the efficacy  
of the processing flowsheet is underway with 
the production of a mixed rare earth sulphate 
in South Africa which will be used for pilot 
testing of the final separation process  
in the USA. As a result of the pilot test work, 
changes may be required to the proposed 
processing flowsheet which could have a 
detrimental impact on the economics  
of the project as set out in the PEA. 

A DFS will need to be completed  
to provide sufficient confidence for project 
development, which may not deliver results 
in line with the PEA. 

Permitting risk

New and updated permits and licences  
will be required to develop the Phalaborwa 
project including, but not limited to, a water 
use licence, waste management licence  
and air emissions licence.

High

Financing risk

The Group’s ability to continue to develop the 
Phalaborwa project and other new business 
opportunities will rely upon its continued 
ability to access financing, both  
at the corporate and project level. 

High

Annual Report & Financial Statements 2023

The Group’s technical team has designed 
and commissioned numerous commercial 
plants in Africa, including completion  
of feasibility studies for rare earth projects, 
and are therefore familiar with alternative 
technical options that may need to be 
deployed if the original strategies prove 
uneconomic. 

The results of the pilot test work programme 
to date, comprising the production of an 
initial batch of mixed rare earth sulphate, 
have been in line with the PEA. This includes 
both metal recoveries of ca. 65% and reagent 
consumption in the process. 

Rainbow is working with specialist consultants 
to compile the technical reports required for 
the permitting process and is aiming to make 
the relevant applications in parallel with work 
on the DFS. 

Whilst the timeframe for the issuance of 
permits is difficult to predict, the Phalaborwa 
project will clean up legacy environmental 
issues at the site, including treating the acid 
water currently associated with the unlined 
gypsum stacks and re-stacking the 
processed gypsum on new lined stacks 
designed in accordance with IFC 
Performance Standards and the Equator 
Principles. Accordingly, the Group is 
confident that the relevant permits will be 
issued to allow the project to proceed. 

The strong economic returns set out in the 
PEA for Phalaborwa are expected to ensure 
funding is available to deliver the DFS and, 
ultimately, the development of the 
Phalaborwa project. 

Management maintains strong relationships 
with key sources of finance. Rainbow has a 
history of securing funding required for the 
Group’s growth plans, including support from 
its cornerstone investors, and management 
expects to be able to secure additional 
funding as required.

PRINCIPAL RISKS AND  
UNCERTAINTIES CONTINUED

Risk 

Comment 

Business impact 

Mitigation 

Rare earth prices

Co-development risk

High

Medium

Rainbow is focused on the identification  
and development of secondary rare earth 
deposits that can be brought into production 
quicker and at a lower cost than traditional 
hard rock mining projects, with a focus on 
the permanent magnet rare earth elements 
neodymium and praseodymium, dysprosium 
and terbium. 

Whilst analysts are predicting strong growth 
in demand for rare earths, prices have been 
volatile in the past. If the underlying rare earth 
basket price of the Group’s development 
projects fall, this reduces potential revenue 
that will impact the long-term profitability  
of the projects and could impact the 
commercial viability of any development. 

The Group’s assets include projects that  
will be conducted in joint arrangements  
or with associates, which reduces the 
Group’s ability to control and manage  
risk and places reliance on partners not 
controlled by the Group. 

At Phalaborwa, Bosveld Phosphates (Pty) 
Limited has a 15% interest in the project and, 
as current owner of the site, their assistance 
is required to ensure the assets necessary  
for the project development are transferred 
at the necessary time into the joint venture 
vehicle and they remain liable for the historic 
environmental liabilities associated with the 
project site. 

The Group’s development pipeline,  
including the Uberaba property in Brazil and 
the opportunity with OCP in Morocco, are at a 
much earlier stage of development. The legal 
framework for the development of a 
commercial operation for these opportunities 
has not been fully defined and terms may 
not be agreed with the owners of these 
assets to allow a development to occur. 

Political risk in 
Burundi

On 12 April 2021, the Government of Burundi 
suspended the export of concentrate 
produced at Gakara. This was followed  
on 29 June 2021 with a suspension of all trial 
mining and exploration activity. All operations 
remain on care and maintenance. 

Low

The Phalaborwa PEA confirmed a low-cost 
operation due to the nature of the rare earth 
mineral resource contained in a chemical 
form in two gypsum stacks, which will not 
require many of the processes associated 
with a primary mineral ore body for the 
extraction of rare earths. The resulting 
operating margin will allow Phalaborwa  
to be resilient against rare earth pricing 
volatility as the project is expected to 
generate strong returns even in a lower  
rare earth price environment. 

The Group aims to negotiate offtake 
arrangements to ensure a commercial 
development is viable in the interests  
of all stakeholders. 

For Phalaborwa, Rainbow has the option  
to acquire the 15% minority interest from 
Bosveld by issuing US$7 million of equity  
in Rainbow Rare Earths Limited. This will 
enable the Group to fully control that project 
and creates a strong incentive for Bosveld 
Phosphates (Pty) Limited to ensure it takes 
the necessary steps to allow the project to  
be developed. 

For the earlier stage projects, Rainbow’s rare 
earths processing expertise and ownership, 
directly or under licence in the relevant 
territories, of the IP rights to develop an 
economic processing flow sheet similar  
to Phalaborwa is expected to ensure that 
suitable commercial terms can be agreed for 
the long term development of these assets.

Due to the re-focus of Rainbow’s business  
on the Phalaborwa asset and growth 
opportunities from the associated processing 
technology, the Directors do not envisage 
investing significant amounts in Burundi  
to develop a formal mineral resource and 
therefore the net assets of the Gakara cash 
generating unit have been impaired to nil in 
the 2023 Annual Report and Accounts.

DIRECTORS’ REPORT

The Directors present their Annual Report and the Financial 
Statements of the Group for the year ended 30 June 2023. 

General 
Rainbow Rare Earths Limited, the parent company of the Group,  
was established in Guernsey on 5 August 2011. On 30 January 2017,  
its shares were listed on the standard segment of the Main Market  
of the London Stock Exchange. 

Business review 
A review of the business during the Year is included in the Chairman’s 
Statement, the CEO’s Q&A, and in the Operating and Financial Reviews. 
The Group’s business and operations and the results thereof are 
reflected in the attached Financial Statements. 

Principal activity 
The Company’s principal activity is the development of rare earth 
minerals projects in South Africa and Brazil. 

Business model 
The basis on which the Company seeks to preserve and generate value 
is through the identification and development of secondary rare earth 
deposits that can be brought into production quicker and at a lower  
cost than traditional hard rock mining projects, with a focus on the 
permanent magnet rare earth elements neodymium and 
praseodymium, dysprosium and terbium. Once operational, the net  
cash generated from the Group’s projects will be used to service the 
Company’s financing, re-invested in further rare earth project 
development opportunities, or (where appropriate) repaid to investors  
in the form of dividends. 

In the short term, this strategy is focused on the Phalaborwa rare earths 
project in South Africa, where a measured and indicated mineral 
resource has been defined contained within gypsum stacks derived 
from historic phosphate hard rock mining. The PEA has confirmed that 
Phalaborwa represents an economically attractive potential source of 
rare earth oxides. 

The Uberaba project in Brazil represents a longer-term prospect; the 
Company is currently carrying out initial test work with its partner Mosaic 
to understand the mineralogy of the deposit better.  

Directors’ remuneration 

Business risks 
A review of the key risks to the Company is set out on pages 46 to 47.

DIRECTORS’ REPORT CONTINUED

Directors’ responsibility statement 
The Companies (Guernsey) Law, 2008 requires the Directors to prepare 
financial statements for each financial period, which give a true and fair 
view of the state of affairs of the Group for that period and of the profit  
or loss of the Group for that period. Under that law they have elected  
to prepare the financial statements in accordance with International 
Financial Reporting Standards as adopted by the EU and applicable law. 
In preparing those financial statements the Directors are required to: 
•
• make judgments and estimates that are reasonable and prudent; 
•

select suitable accounting policies and then apply them consistently; 

state whether applicable accounting standards have been followed, 
subject to any material departures disclosed and explained in the 
financial statements; and 
prepare the financial statements on the going concern basis unless 
it is inappropriate to presume that the Group will continue in business. 

•

The Directors are responsible for keeping proper accounting records 
which disclose with reasonable accuracy at any time the financial 
position of the Group and to enable them to ensure that the financial 
statements have been properly prepared in accordance with the 
Companies (Guernsey) Law, 2008. They are also responsible for 
safeguarding the assets of the Group and hence for taking reasonable 
steps for the prevention and detection of fraud and other irregularities. 
The Directors confirm that they have complied with the above 
requirements in preparing the financial statements. 

So far as each of the Directors are aware, there is no relevant audit 
information of which the Group’s auditor is unaware; having taken  
all the steps the Directors ought to have taken to make themselves 
aware of any relevant audit information and to establish that the  
Group’s auditor is aware of that information.

Website publication 
The Directors are responsible for ensuring that the Annual Report  
and the Financial Statements are made available on a website.  
Financial statements are published on the Company’s website 
(www.rainbowrareearths.com) in accordance with applicable legislation 
in Guernsey governing the preparation and dissemination of financial 
statements, which may vary from legislation in other jurisdictions.  
The maintenance and integrity of the Company’s website is the 
responsibility of the Directors. The Directors’ responsibility also extends 
to the ongoing integrity of the financial statements contained therein. 

Going concern 
The Directors have reviewed the Group’s cash flow forecasts for at  
least 12 months following the reporting date, together with appropriate 
sensitivities and mitigating actions. A full analysis of the Directors’ 
analysis of the going concern status of the Group Is set out in note 2  
to the Financial Statements. 

After considering available cash, loan facilities anticipated to remain 
available, forecast cash flows and anticipated fundraising activities  
the Directors consider that the Group will have adequate resources  
to continue its operational existence for the foreseeable future. However, 
the cash flow forecast includes additional fundraising which is not yet  
in place. The Directors believe that the need to raise further funds 
represents a material uncertainty that casts doubt on this assumption. 
Nevertheless, the Directors continue to adopt the going concern basis  
in preparing the consolidated financial statements. 

Auditor 
BDO LLP has expressed its willingness to continue in office as auditors 
and a resolution to re-appoint BDO LLP will be proposed at the 
forthcoming AGM.

INDEPENDENT AUDITOR’S REPORT 
TO THE MEMBERS OF RAINBOW RARE EARTHS LIMITED

Opinion on the financial statements 
In our opinion, the financial statements of Rainbow Rare Earths Limited (“the Group”): 
•    give a true and fair view of the state of the Group’s affairs as at 30 June 2023 and of its loss for the year then ended; 
•    have been properly prepared in accordance with IFRSs as adopted by the European Union; and 
•    have been properly prepared in accordance with the requirements of the Companies (Guernsey) Law, 2008. 

We have audited the financial statements of Rainbow Rare Earths Limited (“the Group”) for the year ended 30 June 2023 which comprise the Consolidated 
Statement of Comprehensive Income, Consolidated Statement of Financial Position, Consolidated Statement of Changes in Equity, Consolidated Cash Flow 
Statement and notes to the financial statements, including a summary of significant accounting policies. The financial reporting framework that has been 
applied in their preparation is applicable law and International Financial Reporting Standards (IFRSs) as adopted by the European Union. 

Basis for opinion 
We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards 
are further described in the Auditor’s responsibilities for the audit of the financial statements section of our report. We believe that the audit evidence we have 
obtained is sufficient and appropriate to provide a basis for our opinion. Our audit opinion is consistent with the additional report to the Audit Committee. 

Independence  
Following the recommendation of the Audit Committee, we were appointed by the Audit Committee on the 03 October 2016 to audit the financial statements  
for the year ending 30 June 2016 and subsequent financial periods. The period of total uninterrupted engagement including retenders and reappointments is 8 
years, covering the years ended 30 June 2016 to 30 June 2023. We remain independent of the Group and the Parent Company in accordance with the ethical 
requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard as applied to listed public interest entities, 
and we have fulfilled our other ethical responsibilities in accordance with these requirements. The non-audit services prohibited by that standard were not 
provided to the Group or the Parent Company. 

Material uncertainty relating to going concern 
As stated in note 2 the Group has forecasted that it will need to raise additional funding before 31 December 2024, the timing of which is dependent  
on the speed at which the Phalaborwa Definitive Feasibility Study is completed and the amount of funds required to progress the Uberaba opportunity.  
These conditions, along with the other matters set out in Note 2 indicate the existence of a material uncertainty which may cast significant doubt over  
the Group’s ability to continue as a going concern. These financial statements do not include any adjustments that may be necessary if the group was  
not a going concern. Our opinion is not modified in respect of this matter. 

We identified going concern as a key audit matter based on our assessment of the significance of the risk and the effect on our audit strategy.  

Our evaluation of the Directors’ assessment of the entity’s ability to continue to adopt the going concern basis of accounting and in response  
to the key audit matter is described below: 
•    Critically assessing the Director’s cash flow forecast and the underlying assumptions which have been approved by the Board. This included stress testing 
and applying sensitivities to the base cashflow forecast. Our testing included testing the integrity of the model, comparing forecast costs to historical 
actuals, evaluating the consistency of the forecast capital and exploration expenditure within the Group’s strategic plans, and considering the 
reasonableness of the sensitivities applied and outcome of the stress testing;  

•    Verifying cash balances used in the forecast close to the date of sign off of these financial statements, by tracing cash positions against bank statements; 
•    Agreeing the receipt of US$4.7m of the total US$5.4m of funds raised in the September 2023 private placement to bank statements; 
•    Agreeing future cash outflows in respect of loans to underlying agreements. This included assessing the timing of the interest and capital repayments  

on the Finbank loan was appropriately reflected in cashflows commencing from July 2023; 

•    Assessing the reasonableness of the cash outflows for the corporate overhead, which included some contingency and considering the completeness  

of the costs included in the forecast; 

•    Assessing the level of cash outflows assumed for the Gakara mine, which was assumed to remain on care and maintenance for the entire forecast period. 

This involved comparing forecast cash outflows to prior year actuals and considering the completeness of the costs included in the forecast; 

•    Considering the reasonableness of the assumptions in the model regarding the cost and timing of completing the Phalaborwa Definitive Feasibility Study 

(DFS) and pilot plant testing by 30 June 2024; 

•    Considering the ability of the group to secure additional funds in the future based on its history of successful fundraising; and 
•    Reviewing Board minutes and project reports for any indications of unexpected costs, claims or disputes. 

Our responsibilities and the responsibilities of the Directors with respect to going concern are described in the relevant sections of this report.

An overview of the scope of our audit 
Our Group audit was scoped by obtaining an understanding of the Group and its environment, including the Group’s system of internal control, and assessing 
the risks of material misstatement in the financial statements. We also addressed the risk of management override of internal controls, including assessing 
whether there was evidence of bias by the Directors that may have represented a risk of material misstatement. 

Whilst Rainbow Rare Earths Limited is a Company registered in Guernsey and listed on the Standard Segment of the London Stock Exchange in the UK,  
the Group’s principal operations are located in South Africa and Burundi. In approaching the audit, we considered how the Group is organised and managed.  
We assessed the business as being two projects comprising of the Gakara and the Phalaborwa Projects, and a corporate head office function. 

Our Group audit scope focused on the Group’s principle operating entities, Rainbow Rare Earths Limited, Rainbow Mining Burundi, Rainbow International 
Resources and Rainbow Rare Earths (Pty) Ltd. We identified these entities as significant components for the purposes of our financial statement audit, based on 
their relative share of total assets. The significant components accounted for 100% of total assets and were subject to full scope audits conducted by the group 
engagement team, with the exception of fixed assets verification and inventory counts in Rainbow Mining Burundi which were carried out by BDO member firm. 

The remaining component of the Group, being a dormant entity, was considered non-significant, and this component was principally subject to analytical  
review procedures with specific procedures for any significant balances impacting the Group financial statements. 

All audit work (full scope audit or analytical review procedures) was conducted by the group engagement team, with the exception of the fixed assets 
verification and inventory count as detailed above. 

Climate change 
Our work on the assessment of potential impacts on climate-related risks on the Group’s operations and financial statements included: 
•    Enquiries and challenge of management to understand the actions they have taken to identify climate-related risks and their potential impacts  

on the financial statements and adequately disclose climate-related risks within the annual report; 

•    Performing our own qualitative risk assessment taking into consideration the sector in which the Group operates and how climate change affects  

this particular sector; and 

•    Review of the minutes of Board and Audit Committee meeting and other papers related to climate change to assist us in performing our risk  

assessment as to how the impact of the Group’s commitment as set out in the Annual Report may affect the financial statements and our audit. 

We challenged the extent to which climate-related considerations, including the expected cash flows from the initiatives and commitments  
have been reflected, where appropriate, in management’s going concern assessment and viability assessment. 

We also assessed the consistency of managements disclosures included as Statutory Other Information’ on pages 28 - 33 with the financial statements and 
with our knowledge obtained from the audit.  

Based on our risk assessment procedures, we did not identify there to be any Key Audit Matters materially impacted by climate-related risks and related 
commitments.

Key audit matters 
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current period 
and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified, including those which had the greatest 
effect on the overall audit strategy, the allocation of resources in the audit, and directing the efforts of the engagement team. These matters were addressed in 
the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. 
In addition to the matter described in the “material uncertainty relating to going concern” section above, we have determined the matter below to be the key 
audit matter to be communicated in our report. 

     Key audit matter: Accuracy and completeness of the impairment of Burundi Assets (Exploration Assets,  

Property plant and Equipment, Inventory and the Royalty Receivable) 

    Refer to Note 3, 12, 14 & 15 

    In 2021 the Burundian Government put a suspension on trial mining operations and introduced an export ban. The exploration licence has not  

been withdrawn, and the Directors believe that the licence area has significant rare earth mineral potential. However, due to the ongoing suspension  
of mining operations and re-focus of Rainbow’s business on the Phalaborwa asset, the Directors do not envisage investing significant amounts in  
Burundi in the future to develop the resource.  

    Accordingly, the Directors have written the net assets of the Gakara cash generating unit to US$nil, resulting in a US$9,575k impairment  

charge being recorded in the year.  

    The assets associated with the Gakara project include both intangible and tangible fixed assets together with cash, mineral concentrate,  
royalty receivables and consumables held in stock. The liabilities associated with the Gakara project include a loan, decommissioning,  
site rehabilitation and environmental costs, tax liabilities and trade payables.  

    Given the judgements and estimates involved in assessing the accuracy of the impairment charge and recoverability of the unimpaired  

Burundi assets, this is a key audit matter. 

     How the scope of our audit addressed the key audit matter  

    To determine the accuracy of the impairment charge and recoverability of the unimpaired Burundi assets we have undertaken the following procedures: 

     Exploration and evaluation assets, carrying value of nil after a U$8.6m impairment charge.  
    •     We have considered management’s assessment of impairment indicators under IFRS 6 (Exploration and Evaluation of Mineral Resources)  
and have confirmed against Board approved budgets that no substantive expenditure is either budgeted or planned to further explore the  

    area which is an impairment trigger; and 

    •     We have tested the completeness and accuracy of the US$8.6m impairment of exploration assets by confirming no changes were made  

to the exploration assets balance between 2022 and 2023 before impairment 

     Property plant and equipment (PP&E) carrying value of nil after a US$0.7m impairment charge.  
    •     A BDO member firm under our direction and supervision physically verified the existence of a sample of PP&E; 
    •     We considered the requirements of IAS 36 (Impairment of assets) which details PP&E should be held at the higher of value in use and fair value  

less cost to sell, and: 

    -

    -

in considering value in use, we reviewed correspondence between management and the Burundi government which gives no indication of when  
the suspension will be lifted; and we corroborated management’s change of focus from Burundi to Phalaborwa by reviewing internal budgets.  
Based on these procedures we concurred with management that the value in use of PP&E is nil; and  
in considering fair value less cost to sell, we considered management’s ability to sell PP&E, which included consideration of the remote location  
of the mine, the suspension of all mining activities in Burundi, and management’s ability to export the PP&E which also requires government 
approval. Based on these procedures we concurred with management that fair value less cost to sell is nil.  

     Inventory Carrying value of US$0.7m after a US$0.1m impairment charge.  
    The impaired inventory of US$0.1m relates to spares and equipment held at a government warehouse awaiting import clearance.  

Neither management nor ourselves have been able to confirm the existence of this inventory and we concur that it is appropriate to impair it to nil.  

     The remaining inventory on hand is made up of 420 tonnes of rare earth minerals.  
    •     A BDO member firm attended an inventory count at the year-end and tested a sample of volumes and grades of the rare earth minerals; 
    •     We assessed the rare earth minerals were appropriately held at the lower of cost and net realisable value. This included challenging management  

over the timing of when the export ban will be lifted, as until this is lifted the inventory has no realisable value. In the event that the export ban is not  
lifted, and the inventory is not able to be sold, management would use this to asset to partially settle any remaining in country liabilities.  

     Royalty receivable carrying value of nil after a US$0.1m impairment charge.  
    •     We assessed Management’s assumptions to determine the recoverable amount of the receivable, including considering the time that has elapsed  

with no payments having been received.  

     Key observations: 
    Based on procedures performed, we consider that the impairment charges and recoverable values of the remaining Burundi assets to have been  
appropriate determined given the current facts and circumstances, and that the disclosures included within the financial statements that detail  
the significant judgements and estimates arising from the suspension from mining operations to be appropriate.

Our application of materiality 
We apply the concept of materiality both in planning and performing our audit, and in evaluating the effect of misstatements. We consider materiality to be the 
magnitude by which misstatements, including omissions, could influence the economic decisions of reasonable users that are taken on the basis of the financial 
statements.  

In order to reduce to an appropriately low level the probability that any misstatements exceed materiality, we use a lower materiality level, performance 
materiality, to determine the extent of testing needed. Importantly, misstatements below these levels will not necessarily be evaluated as immaterial  
as we also take account of the nature of identified misstatements, and the particular circumstances of their occurrence, when evaluating their effect  
on the financial statements as a whole.  

Based on our professional judgement, we determined materiality for the financial statements as a whole and performance materiality as follows: 

                                                                                                                                                                                              2023

    Basis for determining materiality                                                                                           1.5% of total assets                                                      4% of loss before tax 

Group financial statements 

     Rationale for the benchmark applied                                          Total Assets was determined as an appropriate basis as the principal focus of the Group 

remains the advancement and development of its projects.  

                                                                                                           As such, we consider the users of the financial statements will focus on the statement  

of financial position and total assets of the Group in order to understand the level of  
investment being made. 

                                                                                                           In the prior year, materiality was based on 4% of loss before tax. We considered loss before  
tax to be the most significant determinant of the Group’s financial performance given the 
increased focus on Phalaborwa which made up a lower proportion of the group’s total assets, 
and the costs incurred to keep Gakara on care and maintenance were being expensed in the 
period. Therefore, loss before tax was considered to be a more appropriate materiality base  
as this represents the costs incurred to fund the group in the pre-revenue phase of operation.  

     Performance materiality                                                                                                                                                                         147,000                                                                               112,000 

     Basis for determining performance materiality                    Performance materiality was set at 70% (2022: 70%) of the materiality level based on our 
assessment of a number of factors including the expected total value of known and likely 
misstatements (based on past experience), our knowledge of internal control and 
management’s attitude towards proposed adjustments.  

Component materiality 
We set materiality for each component of the Group based on Group materiality to ensure that the risk of errors exceeding component materiality  
was appropriately mitigated; this was capped due to aggregation risk in line with the ISAs (UK). Component materiality was US$105,000 for each  
component (2022: US$106,000). In the audit of each component, we further applied performance materiality levels of 70% (2022: 70%) of the  
component materiality to our testing to ensure that the risk of errors exceeding component materiality was appropriately mitigated. 

Reporting threshold  
We agreed with the Audit Committee that we would report to them all individual audit differences in excess of US$4,200 (2022: US$3,200).  
We also agreed to report differences below this threshold that, in our view, warranted reporting on qualitative grounds. 

Other information 
The Directors are responsible for the other information. The other information comprises the information included in the Annual Report, other than the financial 
statements and our auditor’s report thereon. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise 
explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, 
consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise 
appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this 
gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material 
misstatement of this other information, we are required to report that fact. 

We have nothing to report in this regard. 

Other Companies (Guernsey) Law, 2008 reporting 
We have nothing to report in respect of the following matters where the Companies (Guernsey) Law, 2008 requires us to report to you if, in our opinion: 
•    proper accounting records have not been kept by the Company; or 
•   
•    we have failed to obtain all the information and explanations which, to the best of our knowledge and belief,  

the financial statements are not in agreement with the accounting records; or  

are necessary for the purposes of our audit.

Responsibilities of Directors 
As explained more fully in the Directors’ responsibilities statement within the Directors Report, the Directors are responsible for the preparation of the financial 
statements and for being satisfied that they give a true and fair view, and for such internal control as the Directors determine is necessary to enable the 
preparation of financial statements that are free from material misstatement, whether due to fraud or error. 

In preparing the financial statements, the Directors are responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, 
matters related to going concern and using the going concern basis of accounting unless the Directors either intend to liquidate the Company or to cease 
operations, or have no realistic alternative but to do so.  

Auditor’s responsibilities for the audit of the financial statements 
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due  
to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that  
an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and  
are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis  
of these financial statements. 

Extent to which the audit was capable of detecting irregularities, including fraud 
Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, 
to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including 
fraud is detailed below: 

Non-compliance with laws and regulations 
Based on: 
•    Our understanding of the Group and the industry in which it operates; 
•    Discussion with management and those charged with governance and also consider legal counsel; and 
•    Obtaining and understanding of the Group’s policies and procedures regarding compliance with laws and regulations. 

We considered the significant laws and regulations to be the applicable accounting framework, Companies (Guernsey) Law 2008, Tax regulations  
and the Listing Rules of the Financial Conduct Authority. 

The Company is also subject to laws and regulations where the consequence of non-compliance could have a material effect on the amount or disclosures in 
the financial statements, for example through the imposition of fines or litigations. We identified such laws and regulations to be Task Force on Climate-Related 
Financial Disclosures (TCFD), local health and safety law, compliance with the rights for Phalaborwa as per the earn-in-agreement, the mining permits and 
export ban of Burundi and the Prevention of Corruption (Bailiwick of Guernsey) Law, 2003. 

Our procedures in respect of the above included: 
•    Review of minutes of meeting of those charged with governance for any instances of non-compliance with laws and regulations; 
•    Review of correspondence with tax authorities for any instances of non-compliance with laws and regulations; 
•    Review of financial statement disclosures and agreeing to supporting documentation; and  
•    Review of legal expenditure accounts to understand the nature of expenditure incurred.

Fraud 
We assessed the susceptibility of the financial statements to material misstatement, including fraud. Our risk assessment procedures included: 
•    Enquiry with management and those charged with governance regarding any known or suspected instances of fraud; 
•    Obtaining an understanding of the Company’s policies and procedures relating to: 
     -
     -
•    Review of minutes of meeting of those charged with governance for any known or suspected instances of fraud; 
•    Discussion amongst the engagement team as to how and where fraud might occur in the financial statements; and 
•    Performing planning analytical procedures to identify any unusual or unexpected relationships that may indicate risks of material  

Detecting and responding to the risks of fraud; and  
Internal controls established to mitigate risks related to fraud.  

misstatement due to fraud. 

Based on our risk assessment, we considered the areas most susceptible to fraud to be management override of controls and areas of judgement  
due to level of subjectivity involved with them. 

Our procedures in respect of the above included: 
•    Fraud enquiries were held with management and those charged with governance to identify whether any instances of fraud were noted in the period.  
•    Testing the financial statement disclosures to supporting documentation, performing testing on account balances which were considered to be a greater 

risk of susceptibility to fraud. These balances relate to our key audit matters as disclosed above.  

•    Making enquiries of management as to whether there was any correspondence with regulators and the Government, in so far as the correspondence 

related to the financial statements and reviewed this correspondence.  

•    Performing targeted journal entry testing based on identified characteristics the audit team considered could be indicative of fraud to address  

the presumed risk of management override of controls, including bribery. For example, we tested capitalisation to property plant and equipment  
or exploration assets with the opposite entry being processed against bank and cash accounts and not against liability accounts.  

•    Reviewing the Group’s year end unadjusted entries, consolidated entries and investigating any that appear unusual as to nature or amount  

by agreeing to supporting documentation; and 

•    Assessing significant estimates made by management for bias. 

We also communicated relevant identified laws and regulations and potential fraud risks to all engagement team members who were all deemed to have 
appropriate competence and capabilities and remained alert to any indications of fraud or non-compliance with laws and regulations throughout the audit.  

Our audit procedures were designed to respond to risks of material misstatement in the financial statements, recognising that the risk of not detecting a material 
misstatement due to fraud is higher than the risk of not detecting one resulting from error, as fraud may involve deliberate concealment by, for example, forgery, 
misrepresentations or through collusion. There are inherent limitations in the audit procedures performed and the further removed non-compliance with laws 
and regulations is from the events and transactions reflected in the financial statements, the less likely we are to become aware of it. 

A further description of our responsibilities is available on the Financial Reporting Council’s website at:  
https://www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.  

Use of our report 
This report is made solely to the Company’s members, as a body, in accordance with Section 262 of the Companies (Guernsey) Law, 2008. Our audit work  
has been undertaken so that we might state to the Company’s members those matters we are required to state to them in an auditor’s report and for no other 
purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company and the Company’s members  
as a body, for our audit work, for this report, or for the opinions we have formed.

FINANCIAL STATEMENTS

NOTES TO THE FINANCIAL STATEMENTS 
FOR THE YEAR ENDED 30 JUNE 2023

1. GENERAL INFORMATION 

Reporting entity 
Rainbow Rare Earths Limited (“the Company”) is a company domiciled in Guernsey and incorporated on 5 August 2011, with company  
registration number 53831, and is a company limited by shares. The Company’s registered office is Connaught House, St Julian’s Avenue,  
St Peter Port, Guernsey, GY1 1GZ. The consolidated financial statements of the Company for the years ended 30 June 2023 and 30 June 2022 
comprise the Company and its subsidiaries. 

2. ACCOUNTING POLICIES 

Basis of preparation 
The Financial Statements of the Company and its subsidiaries (“the Group”) are prepared in accordance with International Financial Reporting Standards 
(“IFRS”) (IFRS and IFRIC Interpretations) issued by the International Accounting Standards Board (“IASB”), as adopted by the European Union. 

The consolidated financial statements have been prepared on a historical cost basis, except for financial instruments measured at fair value through 
profit or loss. Given the development status of the Group’s assets, management do not consider sustainability and climate change as key risks requiring 
significant judgement for the Year. The Group has prepared sustainability disclosures on pages 22 to 33 in line with the requirements set out in the 
listing rules to the extent relevant for a Group without producing assets. 

Going Concern 
As at 30 June 2023, the Group had total cash of US$8.1 million. During Q3 CY 2023 the Group paid out a total of US$7.3 million including costs  
of US$5.7 million to secure an immediate 85% interest in the Phalaborwa project as set out in note 29. On 27 September 2023 the Company 
announced a private placement raising £4.5 million (approximately US$5.5 million) before costs estimated at US$0.1 million, of which £3.9 million had 
been received at 27 October 2023 as set out in note 29. Going forward the Group expects further cash income of £0.6 million from the equity fund raise 
that is subject to shareholder approval, which is expected to be received at the Company’s AGM on 20 November 2023, and has no commitments. 

The Board have reviewed a range of potential cash flow forecasts for the period to 31 December 2024, including reasonable possible downside 
scenarios. This has included the following assumptions: 

Corporate: 
The forecast includes US$3.2 million of ongoing general and administrative costs of the Group over the 18-month period from 1 July 2023  
to 31 December 2024 (the “Period”), based on the current administrative costs of the Group. This includes US$0.2 million in respect of pursuing  
new business opportunities, which will cover only the initial test work at the opportunities identified to date including the opportunity with OCP  
in Morocco and the opportunity with the Mosaic Company in Brazil. 

Management’s reasonably plausible downside scenario includes a 10% contingency for unexpected costs plus a further US$0.25 million per annum  
for business development costs. 

Phalaborwa: 
The forecast includes US$5.7 million of costs relating to the acquisition of the 85% ownership in Phalaborwa, including relevant transaction costs, 
which was announced on 28 June 2023 and paid in Q3 2023 as noted above. The forecast also includes all costs required for the completion of the 
Phalaborwa DFS, estimated at US$5.9 million, inclusive of a 10% contingency. This includes all costs associated with the ongoing pilot test work 
campaign underway in both South Africa and USA. 

The forecast also includes salary and consultant costs of US$0.6 million for the core project team tasked with advancing the project. No further 
contingency on the costs associated with the DFS was considered necessary for management’s reasonably plausible downside scenario as the base 
case forecast includes relevant contingencies. Management’s reasonably plausible downside scenario includes a 10% contingency on the costs of the 
core project team. 

Uberaba: 
As set out in note 29, a memorandum of understanding was signed on 17 July 2023 with Mosaic to jointly develop a process flowsheet and conduct  
a preliminary economic assessment related to the extraction of rare earth elements from Mosaic's phosphogypsum stack in the Uberaba area of 
Minas Gerais in Brazil. At the date of this Report, the Group has no commitments in respect of this project. A detailed budget for the anticipated work 
stream is not yet available and will need to be agreed with Mosaic, but it is noted that management’s reasonably plausible downside scenario would 
not be sufficient for a resource to be defined and a PEA to be developed and further funding may be required to allow for the Uberaba opportunity  
to be de-risked, the timing of which cannot be accurately predicted at this time. 

Gakara: 
The cash flow forecasts assume ongoing care and maintenance costs totalling US$0.6 million including amounts payable under the FinBank loan 
facility in Burundi. The Group has determined that no additional cash outflows will be incurred on Gakara until the export ban and mining suspension 
has been lifted. In the event that the Gakara project did return to operations, stock of rare earth concentrates with a current estimated gross sales 
value of US$1.0 million would be sold to provide the funds to re-commence operations. The re-start would be conditional on the Gakara project not 
requiring additional financial support from Rainbow Rare Earths Limited at then current rare earth prices.

FOR THE YEAR ENDED 30 JUNE 2023

2. ACCOUNTING POLICIES CONTINUED 

Going Concern continued 
Conclusion 
The base case forecast includes a total cash outflow over the Period of US$16.1 million. Management’s reasonably plausible downside scenario,  
which includes a 10% contingency for corporate costs, fixed costs at Phalaborwa and Gakara costs, together with a further allowance for  
business development opportunities, includes a total cash outflow of US$16.9 million. 

At 30 June the Group had US$8.1 million of available cash which together with US$5.4 million of net funds raised in September 2023 provides  
US$13.5 million of available resources, which confirms that the Group will need to raise additional funds before 31 December 2024, the timing of which 
is dependent primarily on the speed at which the Phalaborwa DFS is completed, which is within managements control. Management’s reasonably 
plausible downside scenario suggests that at least US$3.4 million will need to be raised, along with any funds required to progress the Uberaba 
opportunity in Brazil. 

The Board is confident that this funding will be secured, based on its history of successful fundraising. However, it also acknowledges that this funding 
is not, at the present time, in place. Accordingly, the Board acknowledges that the need for additional funding represents a material uncertainty which 
may cast significant doubt on the ability of the Group to continue as a going concern and, therefore, that it may be unable to realise its assets and 
discharge its liabilities in the normal course of business. The financial statements do not include any adjustments that would result if the Group was 
unable to continue as a going concern. 

New and amended standards and interpretations adopted by the Group 
No material changes to accounting policies arose as a result of new standards applied by the Group from 1 July 2022. 

New standards, interpretations, and amendments not yet effective 
Certain new accounting standards and interpretations have been published that are not mandatory for 30 June 2023 reporting periods and have  
not been early adopted by the Group. These standards include:  
•

IAS 1 – Presentation of Financial statements – The classification of liabilities as current or non-current basing the classification on contractual 
arrangements at the reporting date. These amendments are effective for periods beginning on or after 1 January 2024.  
IAS 1 and IFRS Practise Statement 2 – Disclosure of Accounting Policies – Amendments to “Presentation of Financial Statements” and an  
update to “Making Materiality Judgements” to help assist with providing useful accounting policy disclosures. The amendments are effective  
from 1 January 2023 but may be applied earlier. 
IAS 8 Amendments – Definition of Accounting Estimate - The amendments introduce a new definition for accounting estimates: clarifying  
that they are monetary amounts in the financial statements that are subject to measurement uncertainty. The amendments also clarify the 
relationship between accounting policies and accounting estimates by specifying that a company develops an accounting estimate to achieve 
the objective set out by an accounting policy. The amendments are effective for periods beginning on or after 1 January 2023, with earlier 
application permitted, and will apply prospectively to changes in accounting estimates and changes in accounting policies occurring on or  
after the beginning of the first annual reporting period in which the company applies the amendments. 
Amendments to IAS 12 Income Taxes - Deferred Tax Related to Assets and Liabilities Arising from a Single Transaction. These amendments  
are effective for periods beginning on or after 1 January 2023.  
Amendments to IAS 12 - International Tax Reform; Pillar Two Model Rules. These amendments are effective for periods beginning on or after  
1 January 2023.  
Amendments to IFRS 16 - Lease Liability in a Sale and Leaseback. The amendments are effective from 1 January 2024 but may be applied earlier.  
Amendments to IAS 1 - Non-current Liabilities with Covenants. The amendments are effective from 1 January 2024 but may be applied earlier.

These amendments are not expected to have a material impact on the Group. 

Basis of consolidation 
Where the Company has control over an investee, it is classified as a subsidiary. The Company controls an investee if all three of the following elements 
are present: power over the investee, exposure to variable returns from the investee, and the ability of the investor to use its power to affect those 
variable returns. Control is reassessed whenever facts and circumstances indicate that there may be a change in any of these elements of control. 

The consolidated financial statements present the results of the Company and its subsidiaries as if they formed a single entity. Intercompany 
transactions and balances between Group companies are therefore eliminated in full. 

The results of undertakings acquired or disposed of are consolidated from or to the date when control passes to or from the Group. The results  
of subsidiaries acquired or disposed of during the year are included in the Consolidated Statement of Comprehensive Income from the date that 
control commences until the date that control ceases. 

Where necessary, adjustments are made to the results of subsidiaries to bring the accounting policies they use into line with those used by the Group. 

Non-controlling interests in the net assets of consolidated subsidiaries are identified separately from the Group’s equity. Non-controlling interests 
consist of the non-controlling shareholder’s share of changes in equity. The non-controlling interests’ share of losses, where applicable, are attributed 
to the non-controlling interests irrespective of whether the non-controlling shareholders have a binding obligation and are able to make an additional 
investment to cover the losses. On acquisition of a non-controlling interest the relevant non-controlling interest share of equity is extinguished and the 
difference between the fair value of consideration paid and the relevant carrying value of the non-controlling interest is recorded in retained earnings.

2. ACCOUNTING POLICIES CONTINUED 

Foreign currency 
The consolidated financial statements are presented in US dollars, which is also the functional currency of the Company and all of its subsidiaries.  
The Group’s strategy is focused on developing an ethical supply chain for rare earth elements from secondary sources, with its principal project based 
in South Africa and a global pipeline of earlier stage opportunities being developed. All such opportunities will ultimately generate revenue in United 
States Dollars, which is the currency in which rare earth elements are traded internationally. All support services are charged between group 
companies in United States Dollars. The Group is funded by various financial liabilities which are principally denominated in United States Dollars  
and shareholder equity. 

Transactions in foreign currencies are translated to the functional currency of the Group entity at the rates of exchange prevailing on the dates  
of the transactions. At each reporting date, monetary assets and liabilities that are denominated in foreign currencies are retranslated to the functional 
currency at the rates prevailing on the reporting date. Exchange differences on all transactions are recognised in the consolidated statement of 
comprehensive income in the year in which they arise. 

Revenue recognition 
The Group plans to produce and sell separated rare earth oxides from the Phalaborwa project in South Africa and other secondary rare earth  
sources via a mixture of long term off-take contracts and spot sales to global customers. The Group’s Gakara project in Burundi produces a mixed  
rare earth mineral concentrate which was previously sold under a long-term offtake contract with ThyssenKrupp Metallurgical Products GmbH. 

Revenue is recognised on transfer of control of the relevant rare earth product, which can occur at the project site, at a port in transit to the customers 
premises or at the customers premises. 

Rare earth exploration and evaluation assets 
All exploration and evaluation costs incurred are accumulated in respect of each identifiable project area. Costs which are classified as intangible  
fixed assets are only carried forward to the extent that they are expected to be recovered through the successful development of the area or where 
activities in the area have not yet reached a stage which permits reasonable assessment as to whether the deposit is commercially viable and 
technically feasible for extraction. Costs associated with exploration and evaluation include costs related to trial mining and processing when such 
activity is focused on improving the understanding of the ore body. Such costs include the cost of mining, processing and sales costs for concentrate 
produced as a result of trial mining activities, excluding any costs associated with year-end inventory. 

Costs incurred prior to the legal right to a mineral project being obtained are written off immediately. Accumulated cost in relation to an abandoned 
area are written off in full to the statement of comprehensive income in the year in which the decision to abandon the area is made. 

Exploration and evaluation assets associated with an identifiable project area are transferred from intangible fixed assets to tangible fixed assets  
as “project development costs” when the commercial viability and technical feasibility of extracting the deposit has been established. This includes 
consideration of a variety of factors such as whether the requisite permits have been awarded, whether funding required for development is 
sufficiently certain of being secured, whether an appropriate project development plan is established and the results of exploration and evaluation 
data including internal and external assessments. 

Property, plant and equipment  
Property, plant and equipment consists of plant and machinery, project development costs, motor vehicles, computer equipment, and office furniture 
and fittings. 

Property, plant and equipment is initially recognised at cost and subsequently stated at cost less accumulated depreciation and any impairment.  
The cost of acquisition is the purchase price and any directly attributable costs of acquisition or construction required to bring the asset to the location 
and condition necessary for the asset to be capable of operating in the manner intended by management. 

The Group assesses the stage of a development project to determine when it has reached commercial production, at which point the relevant assets 
begin to be depreciated. The criteria used to assess the date at which commercial production is achieved, being the point at which the project is ready 
for its intended use and operating in the manner intended by management, include completion of a reasonable period of testing, the ability to sustain 
commercial levels of production, and engineering sign off on the plant performance. In the case of new project sites, commercial production is 
deemed to have been met when the site has received all necessary permits and approvals (including a certificate of environmental conformity)  
and is in operation. Prior to this period, any costs associated with the project site are capitalised.  

Depreciation 
Property, plant and equipment is depreciated on a straight-line basis over the estimated useful life of the asset. Residual values and useful lives  
are reviewed on an annual basis and changes are accounted for over the remaining lives. 

The applicable depreciation rates are as follows: 

Description                                                                                                                            Useful life 
Plant, machinery, and mine infrastructure                                                  5 years 
Vehicles                                                                                                                  5 years 
Computer equipment                                                                                        3 years 
Office furniture and fittings                                                                               7 years 

Depreciation incurred on equipment used in exploration is capitalised to exploration and evaluation costs.

Impairment of non-financial assets including exploration and evaluation assets 
Exploration and evaluation assets are reviewed regularly for indicators of impairment following the guidance in IFRS 6 “Exploration for and Evaluation 
of Mineral Resources” and tested for impairment where such indicators exist. In addition, these assets are tested for impairment prior to transfer to 
project development costs. In accordance with IFRS 6 the Group considers the following facts and circumstances in their assessment of whether the 
Group’s exploration and evaluation assets may be impaired: 
• whether the period for which the Group has the right to explore in a specific area has expired during the period or will expire in the near future,  

and is not expected to be renewed; 

• whether substantive expenditure on further exploration for and evaluation of mineral resources in a specific area is neither budgeted nor planned; 
• whether exploration for and evaluation of reserves in a specific area have not led to the discovery of commercially viable quantities of mineable 

material and the Group has decided to discontinue such activities in the specific area; and 

• whether sufficient data exists to indicate that although a development in a specific area is likely to proceed, the carrying amount of the exploration 

and evaluation assets is unlikely to be recovered in full from successful development or by sale. 

If any such facts or circumstances are noted, the Group performs an impairment test in accordance with the provisions of IAS 36. In such 
circumstances the aggregate carrying value of the exploration and evaluation asset, together with any associated property, plant and equipment held 
within the relevant cash generating unit, is compared against the expected recoverable amount of the cash generating unit. The recoverable amount 
is the higher of value in use and the fair value less costs to sell. 

Where the carrying amount of an asset or cash generating unit exceeds its recoverable amount, the asset or cash generating unit is considered 
impaired and is written down to its recoverable amount. Impairment losses are recognised in the Income Statement. Impairment losses recognised  
for a cash generation are recognised against goodwill (if any) and then to identifiable assets on a pro-rata basis. 

A previously recognised impairment loss is reversed if the recoverable amount increases as a result of a reversal of the conditions that originally 
resulted in the impairment. This reversal is recognised in the Income Statement and is limited to the carrying amount that would have been 
determined, net of depreciation, had no impairment loss been recognised in prior years. 

Leases 
At inception the Group assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control 
the use of an identified asset, for a period of time, in exchange for consideration. To assess whether a contract conveys the right to control the use of 
an identified asset, the Group assesses whether: 
•

the contract involves the use of an identified asset. This may be specified explicitly or implicitly and should be physically distinct or represent 
substantially all of the capacity of a physically distinct asset. If the supplier has a substantive substitution right, then the asset is not identified; 
the Group has the right to obtain substantially all of the economic benefits from use of the asset throughout the period of use; and 
the Group has the right to direct the use of the asset. The Group has the right when it has the decision-making rights that are most relevant to 
changing how and for what purposes the asset is used. In rare cases where the decision about how and for what purpose the assets is used is 
predetermined, the Group has the right to direct the use of the asset if either: 
-
-

the Group has the right to operate the asset; or 
the Group designed the asset in a way that predetermines how and for what purpose it will be used. 

•
•

At inception or on reassessment of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease 
component on the basis of their relative stand-alone prices. 

The right-of-use asset is initially measured at the present value of the remaining lease payments, discounted using the incremental borrowing rate. 

The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the end of the lease term.  
In addition, impairment indictors for the right-of-use asset is assessed annually and will be adjusted for certain remeasurements of the lease liability. 

The lease liability is initially measured at the present value of the remaining lease payments, discounted using the incremental borrowing rate.  
The liability is subsequently measured at amortised cost using the effective interest method. Lease payments are apportioned between the finance 
charges and reduction of the lease liability using the incremental borrowing rate implicit in the lease to achieve a constant rate of interest on the 
remaining balance of the liability.

2. ACCOUNTING POLICIES CONTINUED 

Environmental rehabilitation costs 
An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the development or 
ongoing production of a project. Such costs arising from the decommissioning of plant and other site preparation work, discounted to their net present 
values, are provided for in full as soon as the obligation to incur such costs arises and can be quantified. On recognition of a full provision, an addition is 
made to tangible or intangible fixed assets of the same amount. Upon commercial production this addition is then charged against profits over the life 
of the project. Closure provisions are updated annually for changes in cost estimates as well as for changes to the anticipated life of the project, with 
the resulting adjustments made to both the provision balance and the net book value of the associated non-current asset. 

Inventory 
Stockpiles of ore (including but not limited to Run of Mine (“RoM”) ore (where applicable), pre-shipment rare earth finished or partially processed 
product stockpiles, or rare earth products in transit but not yet sold) are valued at the lower of historic cost and net realisable value. Historic cost is 
based on an allocation of all relevant costs incurred in bringing the stockpiles to their present condition at the period end (including as appropriate 
mining or reclamation costs, processing costs and transportation costs). Realisable value is based on an estimate of selling price less applicable further 
costs to be incurred to the point of revenue recognition (including as appropriate further expected processing costs, shipment costs, royalties, and 
other fees to be incurred in the course of the sales process). Inventory stockpile costs do not include an allocation of support costs. 

Inventory spares (including tools, parts for equipment, and stocks of consumables) are also valued at the lower of historic cost and realisable value, 
where material. Spares are reviewed at each period end for obsolescence, with provisions applied to those stock lines where realisable value is 
considered to be lower than historic cost. 

Taxation 
Current tax is based on the estimated taxable profit for the period. Taxable profit differs from net profit as reported in the income statement because  
it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. 
In Burundi, when no taxable profit arises, current tax includes a minimum tax charge calculated as 1% of revenue. 

Deferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts of assets and liabilities for financial 
reporting purposes and the corresponding tax bases used in the computation of taxable profit. It is accounted for using the balance sheet liability 
method. Deferred tax liabilities are recognised for all taxable temporary differences and deferred tax assets are recognised to the extent that it is 
probable that taxable profits will be available against which deductible temporary differences can be utilised. The carrying amount of deferred tax 
assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to  
allow all or part of the asset to be recovered. 

Financial instruments 
Financial assets and financial liabilities are recognised on the statement of financial position when the Group becomes a party to the contractual 
provisions of the instrument.  

-

Financial assets 
Cash and cash equivalents comprise cash held by the Group and short-term bank deposits with a maturity of three months or less. 

Trade and other receivables, to the extent they represent financial assets, are measured at initial recognition at fair value and are subsequently 
measured at amortised cost using the effective interest method. A provision is established when there is objective evidence that the Group will 
not be able to collect all amounts due.  

In applying the general model, the Group monitors on a forward-looking basis the expected credit loss, defined as the difference between the 
contractual cash flows and the cash flows that are expected to be received, associated with its assets carried at amortised cost. The impairment 
methodology applied depends on whether there has been a significant increase in credit risk. For trade receivables only, the simplified approach 
permitted by IFRS 9 is applied, which requires expected lifetime losses to be recognised from initial recognition of the receivables. 

Losses are recognised in the income statement. When a subsequent event causes the amount of impairment loss to decrease, the decrease  
in impairment loss is reversed through the income statement.

2. ACCOUNTING POLICIES CONTINUED 

Financial instruments continued 
-

Financial liabilities 
Loans, borrowings and trade and other payables are initially measured at fair value and are subsequently measured at amortised cost using the 
effective interest rate method. They are classified as current liabilities unless the company has an unconditional right to defer settlement of the 
liability for at least 12 months after the statement of financial position date. 

A financial liability is removed from the balance sheet when it is extinguished, being when the obligation is discharged, cancelled, or expired.  
On extinguishment of a financial liability, any difference between the carrying amount of the liability and the consideration paid, including  
any non-cash assets transferred or liabilities assumed, is recognised in profit or loss. A modification or exchange of a financial liability is either 
accounted for as an extinguishment of the original financial liability or a renegotiation of the original financial liability. An extinguishment or 
substantial modification of a financial liability results in de-recognition of the original financial liability and any unamortised transaction costs 
associated with the original financial liability are immediately expensed to the profit and loss account. Where the change in the terms of the 
modified financial liability are not substantial, it is accounted for as a modification of the original liability, with the modified financial liability 
measured at amortised cost using the original effective interest rate. To determine whether the terms of the modified liability are substantially 
different from those of the original one, a qualitative assessment is performed. If it is not already clear from a qualitative assessment that a 
modification has resulted in a substantial change, then quantitative assessment is performed. This includes consideration whether the 
discounted present value of the cash flows under the new terms, including any fees paid net of any fees received and discounted using  
the original effective interest rate, is at least 10% different from the discounted present value of the remaining cash flows of the original  
financial liability. 

Share capital 
Ordinary shares are classified as equity and are recorded at the proceeds received, net of any direct issue costs. 
The nature of the Company’s reserves is set out in note 23. 

Share options 
Equity-settled share-based payments to employees and Directors are initially measured at the fair value of the equity instrument. The fair value  
of the equity-settled transactions with employees and Directors is recognised as an expense over the vesting period. The fair values of the equity 
instruments are determined at the date of grant, considering market-based vesting conditions.  

The fair values of share options are measured at fair value at the date of grant. Where the share options only contain service conditions or non-market 
conditions and the options are issued with a relevant strike price, a Black – Scholes model is used. Where the share options contain market conditions, 
a Monte Carlo simulation model is used and reflected in the fair value of the options granted. Where the share options contain no market conditions 
and do not include a strike price the fair value is assessed by reference to the share price on the date of issue. Details of the assumptions used are 
included in note 22 Share based payments. 

The expected life used in the models is adjusted, based on management’s best estimate of the effects of non-transferability, exercise restrictions  
and behavioural considerations.  

The cost of equity-settled transactions is recognised, together with a corresponding increase in equity, over the period in which the performance 
and/or service conditions are fulfilled, ending on the date on which the relevant employees (or other beneficiaries) become fully entitled to the award 
(“the vesting date”).  

The cumulative expense recognised for equity-settled transactions at each reporting date until the vesting date reflects the extent to which  
the vesting period has expired and the Company’s best estimate of the number of equity instruments that will ultimately vest.  

The income statement charge or credit for a period represents the movement in cumulative expense recognised as at the beginning  
and end of that period.  

No expense is recognised for awards that do not ultimately vest, except for awards where vesting is conditional upon a market condition, which are 
treated as vesting irrespective of whether the market condition is satisfied, provided that all other performance and/or service conditions are satisfied. 

Warrants 
Warrants issued are recognised at fair value at the date of grant. The fair value is measured using the Black-Scholes model. Where warrants  
are issued in respect of services provided, the fair value is expensed on a straight-line basis over the vesting period (if applicable). Where warrants  
are considered to represent a transaction cost attributable to a liability recorded at amortised cost the fair value is deducted from the liability and 
amortised subsequently through the effective interest rate. Where a fixed number of warrants are issued, and the exercise price is in the functional 
currency of the issuer, the warrant fair value is credited to equity. Where the number of warrants is fixed but the exercise price is in a currency other 
than the functional currency of the issuer the instrument fails the “fixed-for-fixed” criteria and is recognised as a financial liability at fair value through  
profit and loss.

3. ACCOUNTING JUDGMENTS AND ESTIMATIONS 

The preparation of financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect  
the application of policies and reported amounts of assets and liabilities, income and expenses. The estimates and associated assumptions are based 
on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis  
of making the judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ  
from these estimates. 

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period  
in which the estimate is revised if the revision affects both current and future periods. Key sources of judgment and estimation uncertainty are: 

Accounting treatment of exploration and evaluation costs 
Significant accounting judgement 
Judgment was required in determining how to treat costs incurred during the Year for the Group’s development projects in South Africa and Burundi. 
For the Phalaborwa asset management note that the project is based on a JORC compliant mineral resource estimate contained within gypsum 
stacks at the Phalaborwa site. The Group has an 85% economic interest in the project. Accordingly, all costs associated with defining the technical 
feasibility and commercial viability of the project are being capitalised under IFRS6.  

For the Gakara asset, management note that the project has been on care and maintenance throughout the Year. Accordingly, none of the costs 
incurred have been focused on improving the understanding of the ore body, and as such all costs have been recognised in the income statement  
in the Year. 

Impairment indicator assessment for exploration and evaluation assets and associated assets (notes 12, 13 and 14) 
Significant accounting judgement 
Judgment was required in determining whether indicators of impairment existed at 30 June 2023 for the Group’s exploration and evaluation assets. 
The Board assessed factors including the remaining licence term, the plans for future exploration and the results of activities to date, together with  
the strategic plans for the asset against the criteria set out in IFRS 6. 

Phalaborwa 
For the Phalaborwa asset, management note the PEA released in October 2022 confirmed a processing flow sheet capable of economically extracting 
the magnet rare earth metals from the gypsum stacks in a low capital and low operating cost environment with strong economic returns. Recent pilot 
test work has confirmed that the rare earth elements are capable of being extracted from the phosphogypsum and upgraded in line with the flow 
sheet set out in the PEA to produce a mixed rare earth sulphate. The mixed rare earth sulphate will be shipped to the USA where the back-end pilot 
plant for the separation of the magnet rare earths recently finished commissioning. Accordingly, management do not consider there to be any 
indicators of impairment for the Phalaborwa asset.  

Gakara 
The assets associated with the Gakara project include both intangible and tangible fixed assets together with cash, mineral concentrate,  
royalty receivables and consumables held in stock. The liabilities associated with the Gakara project include a loan, decommissioning,  
site rehabilitation and environmental costs, tax liabilities and trade payables. 

Despite the ongoing suspension, the Directors note that the Government of Burundi has not suggested that the licence will be withdrawn.  
The Directors also continue to believe that the licence area represents a significant area of rare earth mineral potential. However, the Directors  
do consider that an indicator of impairment exists at 30 June 2023 due to the re-focus of Rainbow’s business on the Phalaborwa asset and  
growth opportunities from the associated processing technology. As such, the Directors do not envisage investing significant amounts  
in Burundi to develop a formal mineral resource and therefore an impairment review is required under IFRS 16 paragraph 20. 

Based on the assessment of both the legal and political position in Burundi, the Directors were unable to foresee a date when the operations  
at the project would be able to restart, and accordingly have written the net assets of the Gakara cash generating unit to nil. In making this judgement, 
the Directors have made the key judgements and estimates detailed below. 

Carrying value of Gakara tangible and intangible assets (notes 12 and 13) 
Significant accounting judgement 
The impairment review of the intangible and tangible fixed assets associated with the Gakara project required an estimate of the value in use and fair 
value less costs to sell for the assets. In making this decision, the Directors were unable to assign any value for the potential sale of the project or the 
separate sale of the tangible fixed assets associated with the project given the nature of the situation, which is subject to political constraints not in 
accordance with Burundi law. Accordingly, the intangible and tangible fixed assets were fully impaired at 30 June 2023 in accordance with IAS36.  
A change in the situation in Burundi could allow the operations to restart in the future, or permit the sale of the project to a third party, which could 
allow the impairment to be fully or partially reversed.

3. ACCOUNTING JUDGMENTS AND ESTIMATIONS CONTINUED 

Valuation of available for sale mineral concentrate (note 14) 
Significant accounting estimate 
Operations at the Gakara project in Burundi are currently on care and maintenance at the request of the Government of Burundi. At 30 June 2023  
the operation has 421 tonnes of available for sale mineral concentrate with an estimated sale value of US$1.0 million carried at cost of US$717k on  
the Group balance sheet as set out in note 14. This concentrate cannot be sold due to an export ban imposed by the Government of Burundi. 
Management note that in the two years since the export ban was imposed the mineral concentrate has not degraded in any way and, due to the lack 
of a ready market for the concentrate in Burundi, the risk of loss through theft was very low. Management assess that it is probable that the current 
export ban will be lifted in due course, although the timing of future sales cannot be accurately predicted. In the event the export ban is lifted, the 
proceeds from the sale of mineral concentrate will either be used to restart operations or to settle existing liabilities. 

Recoverability of royalty receivable (note 15) 
Significant accounting estimate 
Rainbow Mining Burundi SM (“RMB”) has historically overpaid royalties arising from the sale of rare earth concentrate. Whilst the Government has 
accepted in writing that the overpaid royalties are recoverable, no repayment has been received to date. The Directors have made a judgement that 
the royalty receivable is unlikely to be recovered in the near term due to the political situation in Burundi. Given the significant uncertainty of the timing 
and quantum of any future recovery the asset has been fully impaired at 30 June 2023 with a further impairment charge of US$109k recognised in 
impairment of Gakara assets in the Year. Future recovery may differ from management’s best estimate. 

Decommissioning, site rehabilitation and environmental costs (note 20)  
Significant accounting estimate 
The Group’s mining and exploration activities are subject to various laws and regulations governing the protection of the environment. Estimation  
and experience are used in determining the expected timing, closure, and decommissioning methods, which can vary in response to changes in the 
relevant legal requirements or decommissioning technologies. No provision was recorded for the Group’s Phalaborwa project as on-site activities have 
not yet commenced and there is no legal obligation for restoration by the Group with historical environmental liabilities associated with the site 
contractually remaining with the previous owners. 

The discounted provision recognised for the Group’s Gakara project represents management’s best estimate of the rehabilitation costs that will be 
incurred, discounted from the period in which they are judged to be incurred. Actual costs incurred in future periods could differ materially from the 
estimates. Additionally, future changes to environmental laws and regulations, life of mine estimates and discount rates could affect the carrying 
amount of this provision. 

4. LOSS FROM OPERATING ACTIVITIES 

Operating loss includes: 

Employee remuneration (excluding share options)
Share-based payment charge
Audit of the Group financial statements 1
Depreciation
Impairment of Gakara assets 

1. Audit fees include US$179k for the current year and US$6k foreign exchange differences from the prior year.

Foreign exchange losses in the current period arise principally from GBP and ZAR bank accounts, which the Group holds to match future expected 
cash outflows, which depreciated in value against the US dollar during the year. The change in fair value of the warrant liability in the Year represents  
a gain and has therefore been disclosed in finance income.

Rainbow Rare Earths Limited and Rainbow International Resources Limited are subject to 0% income tax in Guernsey. Rainbow Rare Earths 
(Proprietary) Limited is subject to income tax rate in South Africa at 27%. Rainbow Burundi SPRL and Rainbow Mining Burundi SM are subject  
to corporation tax in Burundi at 30%. 

No deferred tax asset has been recognised in respect of the tax losses carried forward as the recoverability of this benefit is dependent on the future 
profitability of the individual entities within the Group, the timing of which is considered insufficiently certain. The total unrecognised potential deferred 
tax assets in respect of losses carried forward in Rainbow Rare Earths (Proprietary) Limited are US$43k (30 June 2022: US$17k).

11. LOSS PER SHARE 

The earnings per share calculations for 30 June 2023 reflect the changes to the number of ordinary shares during the Year.  

At the start of the Year, 524,405,810 shares were in issue. During the Year, a total of 74,452,846 new shares were allotted (see note 21 Share Capital) 
and on 30 June 2023, 598,858,656 shares were in issue. The weighted average of shares in issue in the Year was 536,805,149. 

The loss per share has been calculated using the weighted average number of ordinary shares in issue. The Group was loss making for all periods 
presented, therefore the dilutive effect of share options has not been accounted for in the calculation of diluted earnings per share, since this would 
decrease the loss per share for each reporting period. 

                                                                                                                                                                                                                            Basic and diluted

Only costs relating to the Phalaborwa Project were capitalised during the Year. The Burundi Project has been under care and maintenance throughout 
the Year and, accordingly, none of the costs meet the requirements under the Group’s accounting policy for capitalisation. 

On 12 April 2021, RMB received notification from the Ministry of Hydraulics, Energy and Mines of the Republic of Burundi of a temporary suspension  
on the export of concentrate produced from the trial mining and processing operations at the Gakara Project. On 29 June 2021, a further notification 
was received temporarily suspending all trial mining and processing operations pending negotiations on the terms of the Gakara mining convention 
signed in 2015. 

The Directors have confirmed from independent legal advisors that the mining convention in place between RMB and the Government of Burundi 
remains legally binding on both parties, and that the actions of the Government of Burundi have not been in accordance with that legally binding 
agreement. However, despite ongoing engagement with the Government of Burundi since the export ban was initially imposed, RMB has not  
received permission to re-start operations and is unable to reliably estimate when such a re-start may be possible. 

Since acquiring the Phalaborwa project in December 2020 and the subsequent development of processing technology to recover rare earth elements 
from phosphogypsum as a by-product of phosphoric acid production, the Directors have re-focused the business on secondary sources of rare earth 
elements where they consider higher returns are available. As such, as set out in note 3, the Directors no longer intend to invest significant amounts at 
Gakara to convert the existing resource target to a reserve capable of supporting long term commercial production, resulting in an impairment review 
being carried out for the Gakara exploration and evaluation assets in the year ended 30 June 2023. 

As set out in note 3, based on an assessment of both the legal and political position in Burundi, the Directors consider that the fair value of the Gakara 
exploration and evaluation assets calculated in accordance with IAS 36 is nil and an impairment loss has been recognised. 

FinBank SA hold security over the fixed and floating assets of RMB which include the impaired exploration and evaluation assets associated  
with the Gakara mining permit in Burundi.

As set out in notes 3 and 12, the Directors recognise that the ongoing suspension of all activities of RMB in Burundi and the subsequent decision not 
to commit investment for the conversion of the Gakara resource target to reserves requires an impairment review for the tangible fixed assets relating 
to the project in accordance with IAS36. Based on an assessment of both the legal and political position in Burundi, the Directors consider that the fair 
value of the property, plant and equipment associated with the Gakara project calculated in accordance with IAS 36 is nil and an impairment loss has 
been recognised. 

FinBank SA hold security over the fixed and floating assets of RMB which include the impaired property, plant, and equipment in Burundi.

Finished goods represents 421 tonnes (2022: 421 tonnes) of mixed rare earth concentrate available for export at the Gakara processing plant. 
Notwithstanding the current export ban in Burundi, the Directors note that the stock of concentrate held for sale has not deteriorated over the period 
of suspension and the estimated sale value remains higher than the original cost. Notwithstanding the uncertainty relating to the likely timing of the 
future sale of the concentrate, the Directors consider that the future increases in forecast rare earth prices will ensure that the present value of the 
realisable price for the concentrate will remain above the cost of production and accordingly no provision for impairment has been made at 30 June 
2023 (2022: US$Nil). The Directors recognise that the uncertainty relating to the future sale of the concentrate could impact the carrying value of the 
stock of concentrate, which comprises all of the inventory held at the balance sheet date. Notwithstanding the uncertainty relating to the likely timing 
of the future sale of the concentrate, the inventory is included within current assets on the basis that dialogue to lift the export ban is continuing and 
the sale is expected to occur within 12 months. 

As set out in notes 3, 12 and 13, the Directors recognise the ongoing suspension of all activities of RMB in Burundi and the re-focus of the Rainbow 
business to secondary sources of rare earths. Accordingly, the value of goods in transit held in the port of Bujumbura has been written down to an 
estimated net realisable value of nil during the year ended 30 June 2023 in line with the fixed assets associated with the Gakara project.

VAT recoverable relates to the input VAT recoverable in Burundi (US$137k, 2022: US$194k) and South Africa (US$126k, 2022: US$20k).  
During the year ended 30 June 2023 a revaluation of the Burundi Franc has resulted in the reduction in the US dollar value of the VAT recoverable  
in Burundi. During the year ended 30 June 2021 a tax audit was undertaken in Burundi over the local operating subsidiary, RMB, covering the period 
from 2017 to 2019. The audit concluded that reverse VAT totalling BIF302 million (US$106k) had not been correctly accounted for on several invoices 
received for services supplied to RMB from international suppliers. The reverse VAT is recoverable under Burundi legislation and, accordingly,  
both the asset and liability are recognised at 30 June 2023. 

During the Year an impairment of US$109k was recognised against the royalty receivable as set out in note 3. 

Expected credit losses were assessed at 30 June 2023 considering various potential scenarios, information regarding the counterparty credit risk,  
the historical payment profiles, and forward-looking factors. On the basis that the primary credit risk relates to the reverse VAT recoverable in Burundi, 
which is expected to be paid only on resolution of all matters relating to the suspension of activity in Burundi, no expected credit loss provision was 
considered necessary in the Year (2022: US$Nil).

Tax and social security payables include BIF737 million (US$260k) for taxes provided as a result of a tax audit undertaken in Burundi over the local 
operating subsidiary, RMB, covering the period from 2017 to 2019. Reverse VAT totalling BIF302 million and withholding tax totalling BIF148 million  
had not been correctly accounted for on a number of invoices received for services supplied to RMB from international suppliers. A further BIF20 
million of payroll taxes were found not to have been paid on salaries for casual staff. Penalties totalling BIF182 million on the unpaid taxes have  
also been provided for in accordance with Burundi legislation together with interest up to the balance sheet date totalling BIF85 million. 

The Directors consider the carrying value of trade and other payables approximate to their fair value.

FinBank Loan 
The FinBank loan facility in Burundi is expressed in BIF and carries an interest rate of 15%. Interest on the loan was paid throughout the Year.  
Updated repayment terms were agreed from February 2023, with BIF30 million per month paid until April 2027 (previously BIF50 million per month 
payable until March 2025) covering both principal and interest on a reducing balance basis. This is not a substantial modification of the loan as the 
impact on the net present value of the loan from the modification is less than 10%. During the Year the devaluation of the BIF from US$1:BIF2,062.63  
at 30 June 2022 to US$1:BIF2,840.54 at 30 June 2023 has reduced the US dollar value of the liability by US$133k. 

Under the terms of this loan, FinBank has security over the fixed and floating assets of RMB, the shares of RMB, and the cash held in RMB’s  
FinBank bank accounts. Interest on the loan amounted to US$78k (2022: US$98k).

During the year ended 30 June 2022, a new office lease was entered into in South Africa and the leases for two properties in Burundi initially 
recognised at 1 July 2020 were formally terminated.  

In the year ended 30 June 2023 notice of termination was given on the South African office lease and the applicable amendments to the Lease 
Liability and Right of Use Asset were recorded in the Year to reflect the new termination date. 

The remaining leasehold property in Burundi is subject to an annual agreement, with right of use assets and lease liabilities calculated by reference  
to the Group’s anticipated long-term intentions to renew the lease agreements. 

There are no other lease commitments.

During the Year, 250,000 options lapsed due to an employee leaving the Group. No employee share options were exercised in the Year. The market 
based vesting conditions attached to 1,236,000 nil priced options issued in 2021 were judged at 30 June 2023, with the calculated shareholder return 
for the Company (-23%) being below the median for the basket of investments specified (-22%). The Directors considered the strong post Year-end 
share price performance and waived the market based vesting conditions allowing the options to vest as set out in the table above. The modification 
did not result in an increase in the fair value of the share options due to the share price at the date of the modification being below the share price on 
the original date of grant.

Weighted average exercise price calculated for US$ based warrants on US$:GBP exchange rate ruling on 30 June 2020. 

On 21 February 2020, 2,000,000 warrants were issued to Pipestone Capital Inc (“Pipestone”), in which George Bennett, the Company’s CEO,  
has a beneficial interest. The warrants were issued in lieu of interest on a US$1 million bridging loan provided to the Company as set out in note 18.  
The warrants have a contractual life of four years at an exercise price of 4.55 pence per warrant. The Pipestone warrants are recognised as a  
financial liability at fair value through profit and loss with changes in value in the Year included under Finance Income as set out in note 6. 

As noted above, the Pipestone warrants are classified as a financial liability and are revalued at each period end using a Black-Scholes model,  
which is categorised as a level 3 fair value measurement in accordance with IFRS 13. The inputs into the model were:

Expected volatility was determined by reference to the annual volatility of the Company’s closing mid-market share price on the London Stock 
Exchange. 

The expected life used in the model has been on management’s best estimate for the effects of exercise restrictions and behaviour.

30. FINANCIAL RISK MANAGEMENT 

The Group’s financial liabilities at each period end consist of bank borrowings, leases, unsecured loans and trade and other payables (including 
accrued expenses). The warrants issued in lieu of interest for the Pipestone Loan, as set out in note 18, are measured at fair value through profit  
or loss. All other liabilities are measured at amortised cost. These are detailed in notes 17, 18 and 19. 

The Group has various financial assets, being trade and other receivables and cash, which arise directly from its operations. To the extent that these 
represent financial assets they are classified as assets held at amortised cost. These are detailed in notes 15 and 16. 

The fair values of the Group’s cash, trade and other receivables, borrowings, unsecured loans, leases, trade and other payables and financial liabilities  
at fair value through profit and loss are considered to approximate book value. 

The risks arising from the Group’s financial instruments are credit risk, liquidity risk and market risk (including interest risk and currency risk).  
The risk management policies employed by the Group to manage these risks are discussed below. 

Credit risk 
Credit risk refers to the risk that the Group’s financial assets will be impaired by the default of a third party. The Group is exposed to credit risk on its cash 
and cash equivalents as set out in note 16. Credit risk is managed by ensuring that surplus funds are held in the UK with well-established financial 
institutions of high-quality credit standing. At 30 June 2023, 99% of funds were held with a bank with a long-term A- credit rating (2022: 99%). 

Market risk 
Market risk arises from the Group’s use of interest bearing, tradable and foreign currency financial instruments. It is the risk that the fair value  
or future cash flows of a financial instrument will fluctuate because of changes in interest rates (interest rate risk), foreign exchange rates 
 (currency risk) or other market factors (other price risk). 

Currency risk 
Currency risk refers to the risk that fluctuations in foreign currencies cause losses to the Group. 

The Group is exposed to foreign exchange risk arising from various currency exposures primarily with respect to Sterling and the Burundian Franc. 
Management monitors the exchange rate fluctuations on a continuous basis and acts accordingly. The financial assets and liabilities that include 
significant foreign currency denominated balances are shown below. 

Foreign exchange risk is managed by matching the currency profile of cash holdings to expected future cash outflows.  
Minimal cash is held in Burundian Francs. The table below shows the currency profiles of cash and cash equivalents:

The largest monetary liability exposure and the least stable currency is the Burundi Franc. A 10% movement in the US$:BIF rate would have resulted  
in a gain or loss of approximately US$0.1m (2022: approximately US$0.1m) in the income statement in relation to the cash and cash equivalents  
and trade payables as at 30 June 2023.

30. FINANCIAL RISK MANAGEMENT CONTINUED 

Interest rate risk 
Interest rate risk refers to the risk that fluctuations in interest rates cause losses to the Group. 

The Group and Company have no exposure to interest rate risk except on cash and cash equivalents which carry variable interest rates.  
The Group has no material sensitivity to reasonable changes in variable interest rates. The group monitors the variable interest risk accordingly. 

The Group’s borrowings bear fixed rates of interest. 

Liquidity risk 
Liquidity risk refers to the risk that the Group has insufficient cash resources to meet working capital requirements. The Group manages its liquidity 
requirements by using both short and long-term cash flow projections. The following table sets out the contractual maturities (representing 
undiscounted contractual cash-flows) of financial liabilities:

Ultimate responsibility for liquidity risk management rests with the Directors, who have built an appropriate liquidity risk management framework for 
the management of the Group’s short, medium, and long-term funding and liquidity management requirements. The Group closely monitors and 
manages its liquidity risk. For further details on the Group’s liquidity position, please refer to the going concern paragraph in note 2 of these accounts. 

Capital management 
In managing the capital, the Group’s primary objective is to maintain a sufficient funding base, through debt and equity, to enable the Group to meet its 
working capital and strategic investment needs. This includes ensuring sufficient funds are available to service the Group’s borrowings as they fall due. 
No funds are held in restricted or designated accounts for future debt servicing requirements. In making decisions to adjust its capital structure to 
achieve these aims the Group consider not only its short-term position but also its long term operational and strategic objectives. 

The Group’s primary capital management measure is net debt (borrowings less cash) to total equity, measured as follows: 

Net debt/(net cash) to equity

Total borrowings (note 18)
Less: Cash and cash equivalents
Net (cash) / debt
Total equity
