A YEAR OF TRANSITION
2022 Report and Accounts

HORIZONTE MINERALS PLC 
IS DEVELOPING TWO TIER ONE 
NICKEL PROJECTS IN BRAZIL
Who we are
Horizonte Minerals is a leading nickel company that 
is developing the Araguaia ferronickel project and the 
Vermelho nickel-cobalt project, both high-grade, low­
er quartile of the cost curve, and long mine life projects. 
As a critical component in both stainless steel and electric 
vehicle battery technology, nickel is a key enabler of the 
clean energy transition. Listed on the AiM and TSX Stock 
Exchanges, we have been operating in Brazil for over a 
decade and have a long-term commitment to generate 
sustainable value for the societies and environments 
where we operate. 
What we do
We are constructing Line 1 of the Araguaia Project, 
a 14,500 tonne per annum nickel mine with first 
production due in 1Q 2024 with an initial mine life of 
28 years. The infrastructure of the site is designed to 
accommodate the Line 2 expansion, which will double 
production to 29,000 tonnes per annum. Our second 
Project, Vermelho, is undergoing a Feasibility Study. 
The Project is comprised of a 38-year mine life with 
average annual production expected to be 24,000 tonnes 
of nickel and 1,250 tonnes of cobalt.

Low cost
Both Araguaia and Vermelho 
are expected to be in the lower 
quartile of the cost curve for C1 
costs, recently demonstrated by 
the signing of a ten-year power 
contract for Araguaia, locking in a 
price 30% lower than that used in 
the feasibility study. 
Scalable
Over 3Mt of contained nickel re­
sources and the potential for over 
60,000t per annum production, 
would position Horizonte as a signif­
icant global nickel producer. 
We are building a low-cost, scalable, nickel operation, 
focused on producing a low-carbon product, ethically, 
safely and responsibly
Pará
Brazil
Nickel operation
Nickel is fundamental in the 
production of stainless steel and 
in battery chemistry as part of the 
green energy transition and the 
drive towards the decarbonisation 
and electrification of the global 
economy.
Low carbon 
product
Leveraging the abundant re­
newable energy sources found 
in Brazil, Horizonte is able to 
ensure that the production from 
Araguaia emits lower levels of 
carbon than alternate produc­
ers reliant on hydrocarbons & 
non-renewable power sources. 
Ethically, safely 
and responsibly
Horizonte has a long-standing 
commitment to contribute to the 
sustainable development of the 
communities associated with our 
operations, to conduct ourselves 
ethically in all our business ac­
tivities and with a focus on the 
responsible management of ESG 
aspects of our projects.
Project location
 
Horizonte draws on the country’s 
significant geological resources pro­
viding potential for future growth. 
We benefit from Brazil’s skilled work­
force and well developed infrastruc­
ture, we are proud to be playing an 
important part in developing Brazil’s 
strategically important nickel indus­
try. Following the construction of 
Araguaia, we are securing valuable 
employment for around 450 people in 
the operational phase and expect to 
generate in excess of US$700 million 
of direct socio-economic value over 
the life of mine.

CHAIR'S
STATEMENT 
William Fisher
Interim Non-Executive Chair
I am pleased to present my first Annual 
Report statement as interim Chair of 
Horizonte. Having been a long serving 
member of the Board, I am very familiar 
with the Company, and to that end, I would 
like to reiterate that we find ourselves 
in a truly exciting period of progression. 
The transition from a developer into 
construction is the next phase for the 
business but our objectives, commitments 
and vision have remained the same: 
positioning Horizonte to be a significant 
global 
producer, 
committed 
to 
the 
ethical, safe and responsible production 
of a low-carbon nickel product. We have 
built an extremely capable management 
team and I have every confidence 
that we will deliver on our mission.
Following the completion of our US$633 
million funding package at the end of 
2021, the transformation of Araguaia 
and the rate at which construction has 
advanced is notable and a testament to 
the hard work and commitment of our 
workforce and partners. More than 2,000 
people are now employed on the Project, 
demonstrating 
the 
transformational 
potential for jobs and growth that the 
Project is providing to the local area. 
Given the challenging nature of the market 
across the board in 2022, we believe that 
the standout quality of the asset has been 
the biggest reason for the success of the 
construction fundraise.  Araguaia’s long 
mine life of 28 years (with potential for 
expansion), low-cost, low-carbon nickel 
product is what underpins the business. 
The build-out of the electrification market 
and the move away from carbon as a 
fuel source have also contributed to the 
nickel market’s strong performance over 
the last 12 months. Read more about our 
markets on pages 12-13. 

During the year we also made strong 
progress at our second project, Vermelho, 
a large high-grade, long mine life, scalable 
resource, designed to be a low-cost 
producer of nickel and cobalt for the 
battery industry. Having successfully 
completed a Pre-Feasibility study in 2019, 
this year we initiated a Feasibility study, 
an important step forward in unlocking 
Vermelho’s significant value. Read more 
about Vermelho on pages 22-23.

transitioned from developer 
to construction

Board development
Horizonte’s 
successful 
move 
to 
construction, 
inevitably, 
necessitated 
a 
reinvigoration 
of 
our 
governance 
structures and leadership at Board 
level. It is on this basis that, in 2022, a 
number of changes to the Board were 
effected. I’d like to formally welcome Dr 
Gillian Davidson and Mr Vincent Benoit, 
who joined the Board in March 2022. 
Gillian’s sustainability experience in the 
extractives and natural resources sectors 
is a fantastic asset to Horizonte as we 
transition into a producer, as is her role as 
founding member and chair of the Global 
Battery Alliance, an initiative created to 
drive a sustainable battery value chain. 
Vincent also brings a wealth of knowledge 
in the mining sector with 30 years’ 
experience in corporate finance, business 
development and M&A. Vincent has been 
a partner at La Mancha since 2012, where 
his work on developing greenfield sites 
with Endeavour Mining saw its market 
capitalisation quadruple and positioned 
La Mancha as a leading private investor in 
the gold mining sector. We’re very pleased 
to have their expertise on board, and 
you will likely see new additions to the 
Board in 2023 as we transition towards 
becoming a producing nickel company.
David Hall, my predecessor as Chair, 
Allan Walker and Sepanta Dorri stepped 
down from the Board and I would like to 
thank them sincerely for their important 
contributions to Horizonte’s success in 
recent years. 
The Board remains committed to good 
corporate 
governance, 
the 
Quoted 
Company Alliance’s Corporate Governance 
Code (QCA Code) and to aligning the skills 
and experience of the Directors and 
management with the needs of Horizonte 
as 
it 
advances 
toward 
production. 
Read 
more 
about 
our 
Governance 
on pages 42-49. 
Sustainability
As a Company, we are committed to 
positioning Horizonte as a long-term 
partner for our stakeholders. We have 
always worked hard to ensure that we 
engage effectively with all of our local 
stakeholders around our projects, from 
local individuals and families to municipal 
authorities. 2022 was no exception, with 
the highlight of this engagement being 
our community development agreement 
with Serviço Nacional de Aprendizagem 
Industrial (SENAI), which we signed in July. 
SENAI is Brazil’s leading national industrial 
training provider and our partnership 
is a key component of Araguaia's Local 
Content Initiative to train and develop 
local community members in core skills 
required during Araguaia's construction 
and 
operational 
phases. 
Horizonte 
has funded classrooms and upskilling 
courses in critical skills like welding and 
electromechanical insulation, and so far 
this year over 420 people have enrolled in 
two cohorts, including a high proportion 
of women, which bodes well for a diverse 
and educated future workforce.
As a demonstration of our commitment 
to responsible mining, at the end of the 
year we completed the construction of our 
biodiversity centre, where as part of our 
significant biodiversity programme, we 
will see close to eighty thousand seedlings 
of native species grown on-site each 
year, helping to replant and rehabilitate 
large areas of degraded land following 
prior agricultural practices surrounding 
Araguaia, including biodiversity corridors 
to link key areas of biodiversity habitat 
around the project area. You can read more 
about our sustainability programmes in 
our 3rd annual Sustainability Report found 
on our website as well as an update on 
activities during the year on pages 26-31.
Positioning Horizonte for the future
Our strategy now is to focus on the con­
struction of Araguaia, defining the ex­
pansion potential of Araguaia as well as 
advancing Vermelho towards a construc­
tion decision, thereby delivering value to 
shareholders. As we move through this 
critical phase in our Company’s develop­
ment, on behalf of the Board, I would like 
to take this opportunity to thank all of our 
workforce partners and stakeholders for 
their ongoing contribution towards deliv­
ering on our vision of becoming a signifi­
cant global nickel producer.

REVIEW
Nickel has an essential role to play in delivering the low carbon, renewable energy that the world 
requires to help combat climate change. The International Energy Agency’s roadmap to achieve 
net zero emissions by 2050 identifies the contributions of various renewable technologies to 
electrical capacity. Nickel’s properties in stainless steel and battery technology are helping to 
reduce greenhouse gas emissions - enabling clean energy solutions to be a central part of our 
effort to tackle global warming.
The transition to a net-zero economy 
will be metal-intensive
Nickel’s role in the clean energy transition 
  
Nickel, a naturally occurring, lustrous, 
silvery-white metallic element has out­
standing physical and chemical proper­
ties, which make it essential in hundreds 
of thousands of products. Its biggest use 
is in alloying - particularly with chromium 
and other metals to produce stainless and 
heat-resisting steels, with two-thirds of 
global nickel production used for its man­
ufacture. Here nickel provides toughness, 
strength and enhanced corrosion resist­
ance, significantly increasing the end 
product’s life.
As the world transitions towards a green 
economy, nickel’s role has begun to 
evolve, as its critical role in sustainable 
energy systems and new battery tech­
nology has emerged. The move to energy 
storage systems has largely been driven 
by significant growth in renewable en­
ergy resources, primarily wind and solar. 
In the US, wind and solar made up more 
than half of all new generating capacity 
in the past three years. Asia and Europe 
are also investing billions in renewables. 
However, the challenge is that the wind 
doesn’t blow and the sun doesn’t shine on 
demand. This is why batteries are being 
deployed to capture the energy and re­
lease it when required, helping stabilise 
our complex and widespread electricity 
infrastructure.
Nickel’s role in the clean energy transition, 
includes:
	
~ 325m EVs expected to be in operation 
globally by 2040. A 60Kwh NMC 
battery needs 39kg of nickel
	
~ Carbon Capture & storage - 200t 
of nickel required to capture and store 
1.5mt CO2 / per annum 
	
~ Nickel improves the strength & 
durability of wind turbines. Each 
turbine requires 2,000 kg of nickel 
	
~ Hydro-electric plants need durable 
nickel-rich stainless-steel turbines. 
Global hydro-electric capacity is 
expected to grow 70% by 2040
	
~ Nickel alloys play an important role 
in ensuring the integrity, durability 
& long-term performance of nuclear 
power stations. 
Growing demand in 2022 
  
2022 global nickel demand was 3 million 
tonnes. To put this in context, in 2000 
demand had not surpassed 1.1 million 
tonnes. This demand growth is set to 
continue if the world hopes to achieve the 
targets set out by the Paris agreement on 
climate change. Governments around the 
world have been enacting policy change 
in order to hit these targets, the United 
States of America for instance passed 
the US Inflation Reduction Act in August 
this year, promising US$369 billion for 
climate and clean energy policies, at the 
same time setting out an ambitious tar­
get to extract and process key battery 
minerals locally, with an aim of reducing 
carbon emissions by roughly 40% by 2030. 
Affirmative actions such as this will help 
drive the change towards a green econo­
my and to becoming net zero.
Turning to supply, despite a complicated 
geopolitical situation coupled with the en­
ergy crisis and rising inflation, the nickel 
deficit that emerged in 2021 swung to a 
surplus in 2022 on the back of strong Indo­
nesian supply. The surplus observed was 
driven by low-grade Nickel Pig Iron (NPI), 
while the current Class 1 nickel tightness 
is likely to hold given the potential sup­
ply disruptions and bottlenecks that ma­
jor existing producers are facing and the 
challenges in bringing online the new mine 
supply from outside of Indonesia.
Looking forwards, while Indonesia will 
be the primary source of increased nickel 
supply globally, the country still heavily 
relies on powering their processing plants 
through coal-fired electricity resulting 
in high carbon emissions. This will be a 
key point of difference compared to the 
renewable sources Horizonte will use. This 
is increasingly important as end users and 
consumers focus on transparency and the 
sourcing of the metals that are used in 
their products.   
Accelerating battery demand will 
fundamentally alter the market  
  
Stainless steel continues to be nickel’s 
main driver of demand, representing 
around two thirds of global nickel demand. 
With a balanced demand profile between 
investment and consumption, and rea­
sonable leverage to growing wealth, 
stainless steel offers annuity demand 
growth linked to global GDP. Longer term, 
BMO Commodities research believe that 
demand for nickel in the use of batteries is 
set to match or exceed that from stainless 
steel over the coming years positioning 
Horizonte well to capitalise on the poten­
tial supply demand imbalance. 
Nickel’s volatile year
  
Nickel has continued to attract a lot of 
attention over the course of 2022, in par­
ticular following an unprecedented short 
squeeze in the first quarter of the year, 
resulting in a 250% surge in prices for the 
metal on the London Metal Exchange 
(LME) in the space of twenty-four hours.
Prior to the event, nickel prices were on the 
rise as demand in most nickel consuming 
sectors continued to recover from wide­
spread COVID-19 disruptions two years 
earlier, whilst strong underlying demand 
trends driven by the global energy transi­
tion continued to propel nickel prices higher. 
Following the event, the nickel market 
entered a state of paralysis, with limited 
material being traded given concerns over 
further price volatility and distrust of the 
LME. As we moved through the year, elec­
tric vehicle (EV) demand began to pick up 
as inventories were worked through and 
restocking began, with nickel ending the 
year at US$29,901 per tonne, 43% higher 
than at the start of the year.

Why we 
measure
An indicator of safety in the 
workplace and the effectiveness 
of our management controls 
to protect our workforce. We 
aim to provide a safe working 
environment for all our people
An indicator of environmental 
and social impact and the 
effectiveness of management 
controls to protect the area 
in which we operate, key to 
our long-term success. We 
operate in an environmentally 
conscientious manner and 
minimise the impact of our 
activities, targeting zero 
environmental incidents.
An indicator of the socio-economic 
benefit to our host communities and 
our effectiveness to enhance our local 
economic participation in Pará state. 
We remain committed to delivering 
shared value to our local communities, 
partially achieved through creating 
employment opportunities for local 
community members. We refer to 
local employment as people from 
Pará state, not Brazil as a whole 
given the vast majority of our people 
are Brazilian
Vital for the continued 
growth of Horizonte and our 
ability to deliver Araguaia 
on time
An indicator of fiscal control 
and management’s ability 
to preserve value. Provides 
the capex budget for the

Performance
We continue our 
demonstrable track 
record of zero LTIFR

transitions into an operator, the Company 
would expect for the downward trend 
to reverse, as we train more people from 
Pará state

EXECUTIVE’S 
REVIEW
Jeremy Martin
CEO
A ground breaking year 
for Horizonte
It is a pleasure to reflect on the achieve­
ments of 2022 which was a ground break­
ing year for Horizonte and has laid the 
foundations for the years ahead, position­
ing the Company to be a significant global 
producer, committed to the ethical, safe 
and responsible production of a low carbon 
nickel product.  
Araguaia Nickel Project 
Our focus for 2022 at Araguaia was to 
secure the funding, build our team, award 
key equipment and construction contracts 
required for construction and the move to 
operations, commencing our 24-month 
journey to becoming a nickel producing 
Company. We’re delighted to have fin­
ished the year having advanced construc­
tion by 34% and importantly, remain on 
track to produce first metal in Q1 2024.
The 2022 reporting period began by clos­
ing out the Araguaia construction funding 
package, in which a total of US$633 mil­
lion was raised comprising a combination 
of senior debt and equity with support 
from a number of high-quality, long-term 
financial institutions and leading mining 
sector investors. By the end of the year 
and following a multi-year effort to de-
risk Araguaia, we were able to success­
fully access the low-cost debt and draw 
down on the first tranche of funds. 
The rigorous due diligence process, and 
the extensive list of obligations that Hori­
zonte was required to meet to access this 
funding, should provide all our stakehold­
ers with confidence in the robustness 
of Araguaia and the quality of the team 
working on the project.
The first debt drawn-down milestone 
demonstrates that we had made signif­
icant progress on construction and were 
able to satisfy the Senior Lenders that we 
had, among others;
i.	
shown that Araguaia is funded through 
to completion and first cash flows 
following the subsequent ~US$80m 
equity raise; 
ii.	
made significant progress with 
construction, and in line with the 
project schedule;
iii.	 awarded all of the key material 
contracts, including equipment 
supply, Engineering Procurement and 
Construction Management (EPCM), 
port access and power supply; 
iv.	 have a long-term offtake in place for 
100% of Araguaia’s production from 
line 1 with a high-quality counterparty 
in Glencore; and lastly, 
v.	
have built out an experienced team to 
deliver the Project.
18
HORIZONTE MINERALS 2022 ANNUAL REPORT
To highlight, the most critical of these 
contracts, is the low-cost power contract. 
Electrical energy makes up approximately 
a third of our operating costs, so having a 
power contract with renewable sourcing, 
at the extremely competitive pricing 
that we were able to lock in, means that 
Araguaia will be operating in the lowest 
quartile of the cost curve for at least the 
ten-year duration of the initial contract life. 
Furthermore, this contract demonstrates 
our ability to become one of the lowest 
CO2 nickel producers, a major competitive 
advantage when compared to nickel peers. 
Turning to the physical progress that we 
saw on the ground at Araguaia, 2022 
was a hugely transformative year in the 
process of developing the greenfield site 
into a producing asset. The foundations 
of the furnace and rotary kiln are now 
well-advanced and earthworks are close 
to completion. To facilitate reliable power 
to site, a 125 kilometre, 230kV powerline 
is being constructed and pre-assembly of 
the towers and construction of the main 
substations at site made good progress. 
 
Vermelho
Horizonte has a second Tier 1 asset in Ver­
melho. 100% owned, it is an excellent op­
portunity to develop a low-cost supply of 
nickel and cobalt to meet the fast-grow­
ing demand due to global efforts to tran­
sition to net zero emissions. 
In October 2022 we awarded the prin­
cipal engineering contract to undertake 
the Feasibility Study (FS) at Vermelho to 
Wood plc, a major milestone in advancing 
the project through to a funding decision. 
Wood is a global engineering and techni­
cal services provider with extensive ex­
perience specifically in the nickel sector, 
and undertook the original Vermelho FS 
for its previous owner, Vale, from 2003 to 
2006, resulting in a positive construction 
decision. We anticipate results from the 
Feasibility Study in 1H 2024.
We were also pleased to announce the 
filing of the Social and Environmental 
Impact Assessment (EIA) for Vermelho in 
late 2022, an essential part of the per­
mitting process of the project. Approval 
of the EIA and subsequent granting of 
a preliminary licence is expected during 
2024, the first stage in a three-stage 
environmental licencing process to devel­
op a mine in Brazil. This filing followed an 
18-month period where Horizonte, in con­
junction with Rambol Group (“Rambol”) (a 
leading global environmental and social 
consultancy firm) together with Integra­
tio (a leading Brazilian social consultancy 
firm), undertook the collection and analy­
sis of the baseline social and environmen­
tal data specified by the Pará State Secre­
tariat for Environment and Sustainability 
(SEMAS), to reflect the current physical, 
biological and social settings at Vermelho. 
Health and Safety first
Alongside the difficult macro inflation­
ary environment, there have been some 
challenges specific to the construction 
phase. Brazil itself experienced a sudden 
step-up in industrial activity in 2022 fol­
lowing COVID-19 disruption, meaning that 
construction contractors were scarce, as 
was the labour force. Securing and main­
taining our high-quality team at Araguaia 
has therefore been an added challenge, but 
one which we have managed to overcome. 
We now have over 2,000 people working at 
site, with this number expected to increase 
to 3,100 by the end of Q2 2023. Notwith­
standing this sharp increase in employ­
ment and activity on site, we are extremely 
proud to have lost zero hours to injury this 
year, giving us a lost-time injury frequen­
cy rate (“LTIFR”) rate of 0.00, for the fifth 
consecutive year. There is of course no 
place for complacency and the health and 
safety of our people remains central to 
everything we do. Further information re­
lating to our health and safety can be found 
on pages 28-29 of this report and also in 
our 3rd annual Sustainability Report found 
on our website.
Building out our Team
As mentioned above, 2022 saw the Hori­
zonte owners team continue to grow as 
well. At the beginning of the year, we had 
a team of around 25 people. By year-end 
this had grown close to 150 people span­
ning across various disciplines from envi­
ronmental and social-focused activities 
to commissioning and Business readiness 
professionals. Creating a strong working 
culture is key for 2023 as we look to en­
gage our people over the long term to instil 
a culture that encourages commitment to 
results, empowerment, flexibility, collab­
oration, transparency and participation. 
New Chair
I’d like to welcome Mr William (Bill) Fisher 
to the role of Interim Chair of the Board. 
Bill has served alongside me on the Board 
for the past eight years, so he is very fa­
miliar with the business. We have always 
had a view that we want to maintain 
continuity throughout the construction 
stages, and as we move into ramp-up, Bill 
brings this required balance. 
2023 Objectives
Looking ahead to the coming 12 months, 
we are cognisant of the work that lies 
ahead. Our primary focus will be on de­
livering Araguaia on-time, on-budget 
and safely. We are targeting cold com­
missioning towards the end of 2023 with 
hot commissioning and subsequent first 
nickel in 1Q 2024. Alongside this work, 
we are planning to conduct a feasibility 
study on the second line at Araguaia, a 
relatively low capex project that will dou­
ble production from 14,500 tonnes per 
annum to 29,000 tonnes per annum. Ver­
melho workflows will be centred around 
the Feasibility study and EIA permitting 
process, both expected to be finalized in 
2024.  Although these objectives are, in 
practice, considerable undertakings, we 
are reassured by the progress already 
made across the Group, and are confident 
in the ability of our teams on the ground 
to deliver.  
Thank you
To conclude, I would like to thank all our 
stakeholders for your continued support 
which is never taken for granted. I would 
also like to take this opportunity to direct­
ly thank the Horizonte team, led on the 
ground in Brazil by Mike Drake, our Head 
of Projects and Leo Vianna, our Project 
Director. The whole team has achieved 
many significant milestones this year. We 
have entered 2023 with confidence and 
look forward to delivering and communi­
cating our progress as we continue to un­
lock value from across our portfolio.

Key operational developments in the year
 
2022 was a transformational year for 
Araguaia having broken ground in May 
when 
construction 
began. 
Over 
the 
following months, earthworks transformed 
the site, preparing the groundwork ahead 
of the plant foundations being laid mid-year. 
Construction work is now into the electro 
mechanical installation phase where steel 
work is being erected. By 31 December 
2022, project construction had advanced 
34%, importantly remaining on schedule for 
first nickel by 1Q 2024. 
As of 31 December, around US$400m of 
a total US$537m had been committed, 
representing close to three quarters of the 
total budget.  
About the project
 
Araguaia is a 100% owned project compris­
ing of an open pit nickel laterite operation 
that will mine a 27.3 Mt mineral Reserve, 
part of a larger 119 Mt mineral resource. 
Annually, line 1 is designed to produce 
52,000 tonnes of ferronickel (FeNi) con­
taining 14,500 tonnes of nickel over a 28-
year mine life. The metallurgical process 
comprises of a Rotary Kiln and Electric 
Furnace (RKEF), a proven technology with 
over 60 years of commercial experience 
in more than 30 operations worldwide, 
three of which are located in Brazil, oper­
ated by Anglo American and Vale. 
After a construction period expected 
to last 24 months and an initial ramp-
up period of 12 months, the plant will 
reach full capacity of approximately 
900,000 tonnes of dry ore feed per year. 
The FeNi product will be transported by 
road to the port of Vila do Conde for sale 
to overseas customers. 
The Value Engineering Study and sub­
sequent Execution Preparation Phase 
work has optimised the RKEF flow sheet 
and worked to establish integrated 
process islands with tier one suppliers 
linked to the Export Credit Agency (ECA) 
project financing. 
A key part of the Stage 1 project design 
was that the RKEF plant and associated 
infrastructure 
was 
designed 
to 
accommodate the addition of a second 
RKEF process line (Line 2 expansion), 
which is intended to double Araguaia’s 
production capacity from 14,500 tonnes 
nickel per annum up to 29,000 tonnes 
per annum nickel. The Project Mineral 
Resource inventory has the grade and 
scale to support the planned increase 
in plant throughput from 900 kt/pa 
(Stage 1) to the Stage 2 rate of 1.8 Mt/pa 
supporting the twin line RKEF flow sheet. 
The Stage 2 expansion assumes operating 
at a Stage 1 production rate of 900 kt/pa 
for three years, then expand the plant to 
1.8 Mt/pa via the addition of a second line.

About the project
 
Vermelho is a 100% owned project locat­
ed in the Carajás mining district, an area 
that features well-developed infrastruc­
ture and abundant hydroelectric power. 
Comprising of a planned 38-year mining 
operation through an open pit nickel lat­
erite mine, Vermelho has a Probable Min­
eral Reserve of 141.3 million tonne (at a 
cut-off of 0.7% Ni) and is forecast to pro­
duce 924,000 tonnes of nickel contained 
in nickel sulphate and 36,000 tonnes of 
cobalt contained in cobalt sulphate over 
the life of mine. 
The Vermelho project pre-feasibility study 
utilised a hydro-metallurgical process 
comprised of a beneficiation plant where 
ore is upgraded prior to being fed to a 
High-Pressure Acid Leach (HPAL) plant. 
The plant will be constructed in two phases, 
with an initial capacity of 1 Mt per annum 
(Mt/a) autoclave feed (Stage 1). After three 
years of production, a second process train 
(Stage 2 Expansion) will be constructed, 
which will effectively double the autoclave 
feed rate to 2 Mt/a. The Stage 1 plant and 
project infrastructure will be constructed 
over a 31-month period. The MHP product 
will be transported by road to the port of 
Vila do Conde (the same facility planned for 
Araguaia) for sale to overseas customers. 
At full production capacity, the Project is 
expected to produce an average of 24,000 
tonnes of nickel and 1,250 tonnes of 
cobalt per year.
Key operational developments 
in the year
 
A Feasibility Study (FS) was initiated in 
2022 with results due to be published in 
1H 2024. In parallel with the FS, Horizonte 
submitted the Social Environmental Impact 
Assessment (“EIA”) with the Pará State 
Environmental Agency (“SEMAS”), which 
forms an essential part of the permitting 
process, and the Company is targeting the 
approval of the EIA and subsequent grant­
ing of a preliminary licence in during 2024. 
Over the coming 
months, 
Horizonte 
will continue to work 
closely with local stake­
holders as Vermelho is 
expected to contribute signif­
icant employment opportunities 
for the region and deliver significant 
socio-economic value.

KPI’s are not GAAP measurements and are 
not intended to be a substitute for these 
measures. The KPI’s used by the Group may 
not be the same as those used by other com­
panies and so should not be used as such. 
Administrative expenses as a percentage of 
total assets have decreased, as a result of 
financing secured during the year to finance 
the Araguaia project construction and in­
creased activity in advancing the Araguaia 
project which was capitalised to the Mine 
Development asset.
Exploration costs capitalised predominant­
ly relate to expenditure on the Araguaia 
project construction. This amount excludes 
capitalised borrowing costs as a result of 
the Royalty financing arrangement, con­
vertible loan notes and loan facilities. It also 
excludes the capitalised environmental re­
habilitation provision. 
During the current year US$175 million was 
secured to advance the Araguaia project 
construction. US$95 million (US$65 million 
convertible loan notes, US$25 million cost 
overrun facility and US$5 million first 
utilisation on senior debt facility) was part 
of the US$633 million funding package 
concluded in December 2021 to finance 
the construction of the Araguaia project. 
Gross proceeds of US$80million was 
secured through an equity fundraise as the 
forecast capital cost for the construction 
of the Araguaia Project increased due 
global inflationary pressures, engineering 
improvements to de-risk the project and to 
accelerate engineering studies and basic 
engineering for the development of line 2 
at Araguaia, as well as further invest in the 
decarbonisation strategy for the Project.
Simon Retter
Chief Financial Officer
Loss for the year
The loss for the year is US$5.3 million com­
pared to a loss of US$13.4 million in 2021. 
This was primarily due to increased head­
count and activity in securing the financing 
for the construction of the Araguaia Project, 
gain on change in fair value of convertible 
loan note embedded derivative, overall net 
foreign exchange gain due to the weakening 
of the Pound Sterling to the US Dollar and an 
increase in net finance cost. 
The Group has continued to keep a tight 
control on its administrative costs, but they 
are expected to rise as the Group increases 
its headcount and progresses with the con­
struction at Araguaia as well as the contin­
ued advancement of Vermelho. As a result of 
this the administrative expenses increased 
during the year from US$7.8 million to 
US$12.5 million.
The convertible loan notes issued during the 
year were classified as a hybrid financial in­
strument, whereby a debt host liability com­
ponent and an embedded derivative liability 
component was determined at initial rec­
ognition. The movement in the embedded 
derivative fair value from initial recognition 
to the year-end date was a gain of US$6.8 
million. For further details on the valuation 
refer to note 22. 
The value of the Mine Development asset 
and intangible assets has increased signifi­
cantly during year due to the additions aris­
ing from the Araguaia Project construction 
and the capitalisation of interest. During 
the year US$13.2 million of borrowing costs 
was capitalised to the Mine Development 
asset for the Araguaia Project compared to 
US$7.1 million in 2021. The net finance costs 
of US$6.4 million is primarily the borrowings 
costs as a result of the Vermelho royalty 
agreement. These borrowing costs are not 
capitalised as the project has not yet com­
menced development.
Furthermore, total comprehensive loss at­
tributable to equity holders of US$10.9 mil­
lion included loss on currency translation dif­
ferences of US$6.7 million. This was due to 
the weakening of Pound Sterling against the 
USD as at 31 December 2022, as compared 
to 31 December 2021. The BRL strength­
ened against the USD and GBP as at 31 De­
cember 2022 when compared to 31 Decem­
ber 2021.
Intangible Assets & PPE
Intangible Assets & PPE, which comprise 
both the Araguaia and Vermelho projects, 
have increased to US$ 276.8 million as at 31 
December 2022 as compared to US$67.4 
million at 31 December 2021. The Group in­
curred US$184million in capital expenditure 
relating to the Araguaia Project construction; 
as well as borrowing costs capitalisation of 
US$13million. 
There was also a foreign exchange revalua­
tion gain of US$7 million due the strength­
ening of the BRL. The exploration assets of 
the business are recorded in the functional 
currency of Brazil, the country in which they 
are located.
Trade and other receivables
Included in trade and other receivables are 
prepaid transactions costs of US$42 million 
(2021: US$12.6million) relating to the senior 
debt finance facility. The transaction costs 
will be offset against the debt when it is 
drawn down.
Cash and cash equivalents
The group held cash and cash equiva­
lents of US$154 million compared to 
US$210.5 million in the prior year. The de­
crease was a result of funds spent in the 
Araguaia Project construction. 
Royalty Liability
The Group has secured two royalty financing 
arrangements of US$25million each for each 
of its projects -Araguaia and Vermelho.
The Araguaia royalty finance secured in 2019 
has been recognised as a liability and valued 
using the amortised cost basis at  US$48.8 
million at 31 December 2022 (US$44.5 mil­
lion at 31 December 2021). This funding is 
not repayable until the project enters into 
production and following that the royal­
ty payments are made at a royalty rate of 
2.95%. The royalty is due on revenue less 
some associated costs on a quarterly basis 
and has been revalued based on the expec­
tation of the future royalty payments under 
the agreement using the effective interest 
method. Included in the agreement are cer­
tain embedded derivatives which can under 
certain circumstances result in the Company 
having the ability to buy back certain levels 
of the royalty, the buy-back price is driven by 
the holder obtaining certain milestones on 
its return on investment. The result of these 
options is a derivative asset being recognised 
on the balance sheet at a fair value of  US$5 
million (2021: US$4.95 million). 
The Vermelho royalty finance secured in 
2022 has been recognised as a liability and 
valued using the amortised cost basis at 
US$41 million at 31 December 2022. This 
funding is not repayable until the project 
enters into production and following that 
the royalty payments are made at a royalty 
rate of 2.1%. The royalty rate will increase to 
2.25% if substantial construction of the Ver­
melho Project has not commenced within 
5 years of the closing date, 30 March 2022. 
The royalty is due on revenue on a quarterly 
basis and has been revalued based on the 
expectation of the future royalty payments 
under the agreement using the effective 
interest method. Included in the agreement 
are certain embedded derivatives which 
can under certain circumstances result in 
the Company having the ability to buy back 
certain levels of the royalty, the buy-back 
price is driven by the holder obtaining certain 
milestones on its return on investment. The 
result of these  options  is a  derivative asset 
being recognised on the balance sheet at a 
fair value of  US$9.5 million. For more details 
on the royalty financing arrangements, refer 
to note 21 of the financial statements.
Convertible loan note liability
The Company issued convertible loan notes 
to the value of US$65 million at an interest 
rate of 11.75% with interest accruing quarter­
ly in arrears. The convertible loan notes were 
issued at a discount of 5.75%. The maturity 
date of the instruments is 15 October 2032.
At any time until the Maturity Date, the 
Noteholder may, at its option, convert the 
notes, partially or wholly, into a number 
of ordinary shares up to the total amount 
outstanding under the Convertible Note 
divided by the Conversion Price. The con­
version price is £1.268/US$1.71.
The convertible loan is a hybrid financial in­
strument, whereby a debt host liability 
component and an embedded derivative 
liability component was determined at 
initial recognition. For convertible notes 
with embedded derivative liabilities, the 
fair value of the embedded derivative li­
ability is determined first and the resid­
ual amount is assigned to the debt host 
liability. Thereafter the debt host liability 
is valued using the amortised cost basis. 
At 31 December 2022 the total carrying 
value for the convertible loan notes was 
US$59 million. For more details on the 
convertible loan notes refer to note 22 of 
the financial statements.
Senior debt facility
On 7 December 2022, the Group satis­
fied all conditions precedent for the first 
utilisation under the senior debt facility of 
US$346.2 million. The first utilisation was for 
US$5million.
The total senior debt facility is US$346.2mil­
lion (Commercial Facility US$200million and 
ECA Facility US$146.2million). The final ma­
turity date on the Commercial Facility is 15 
July 2030. The final maturity date on the ECA 
Facility is 15 July 2032.
Both the Commercial and ECA facilities 
are valued using the amortised cost basis. 
At 31 December 2022 the total carrying 
value for the senior debt facility is US$4.3 
million. For more details on the senior 
debt facility refer to note 24 of the finan­
cial statements.
Cost overrun facility
On 30 November 2022, the Group satisfied 
all conditions precedent in relation to the cost 
overrun facility (COF) and had received all COF 
funds from Orion. Access to the COF funds 
is restricted and will only be available in the 
case of a cost overrun against the Araguaia 
Project construction schedule and budget.
The COF is US$25million with an interest 
rate of 13% and a maturity date of 15 Octo­
ber 2032. Interest will be calculated quarterly 
and be payable in arrears.
The COF is valued using the amortised cost 
basis. At 31 December 2022 the carrying val­
ue of the COF was US$23.8 million. For more 
details on the COF refer to note 23 of the fi­
nancial statements.

The Group is not yet producing minerals and 
so has no income other than bank interest. 
Consequently, the Group is not expected 
to report profits until it is able to profitably 
develop or dispose of its exploration and 
development projects. Horizonte Minerals 
Plc changed its presentation currency from 
Pounds Sterling to US Dollars effective 1 
January 2022. The presentation currency 
has been revised as the financing package 
concluded by the Group to construct the Ara­
guaia project is denominated in US Dollars 
and future revenues will also be in US Dollars. 
The board therefore believes that US Dollar 
financial reporting provides more relevant 
presentation of the Group’s financial posi­
tion, funding and treasury functions, financial 
performance and its cash flows. The principal 
financial key performance indicators (‘KPIs’) 
monitored by the Board concern levels and 
usage of cash. The main financial KPIs for the 
Group allow it to monitor costs and plan fu­
ture exploration and development activities 
and are as follows:

SUSTAINABILITY 
GOVERNANCE
As an experienced non-executive direc­
tor and sustainability practitioner, the 
feedback I receive from stakeholders that, 
‘companies with good governance are 
more likely to have enhanced environ­
mental and social practices relative to 
their peers’, resonates with me.
The last year marked a number of im­
portant achievements for Horizonte, not 
just in the development of our Araguaia 
project, but also in the further evolution 
of our governance framework and asso­
ciated systems.
I am delighted to be the Chair of Horizon­
te’s inaugural Sustainability Committee, 
established in April 2022. Our vision to be a 
globally significant, sustainable nickel produc­
er, means that sustainability plays a critical 
part in our overall business strategy.  The 
mandate of the Sustainability Committee 
has wide-reaching objectives that reflect 
our strategy:
	
~ maintaining healthy and safe work 
places, environmentally sound and 
responsible resource development, 
good community relations and the 
protection of human rights;
	
~ promoting the appropriate culture, 
behaviours and actions in relation to 
these matters; and
	
~ communicating the Board’s commit­
ment to these matters to the Group’s 
employees, contractors and other 
stakeholders.
The Sustainability Committee will meet 
three times a year, including a visit to our 
operations in Brazil, to provide oversight, 
but also to support and promote leader­
ship in sustainability throughout the Hori­
zonte. In fact, during our October 2022 visit 
to Brazil I was impressed by the excellent 
programs designed to increase the number 
of local people in our workforce.  On a visit 
to our ‘Transforming Horizons’ partnership 
with SENAI, I met a lady with her infant 
grand-daughter, who was studying to be­
come a worker at our mine, whilst her own 
daughter was studying university night 
classes. I was thrilled to hear that the pro­
gram was recognised in the ESG Category 
of the Ser Humano Awards in Brazil.  
Within the workplace we are supported 
by local, Pará State and Brazilian compa­
nies and I have been delighted to see the 
increasing participation by these teams in 
our safety programs.  Our programs have 
a strong behaviour-based safety focus and 
leading indicators to support this.  Con­
tracting partners who initially struggled 
to participate are now significantly better 
performing, with the resulting benefits to 
workplace safety and health. Look at our 
highlights overleaf to see these results. 
The discussions we have had on advanc­
ing our enterprise risk management (ERM) 
and materiality processes also brought 
me great satisfaction.  Risk management 
is the foundation of how we demonstrate 
respect and caring for our stakeholders, 
and most importantly, those who may be 
impacted – positively and negatively – by 
our activities. This year we invited, for the 
first time, a number of external stake­
holders to participate in our materiality 
assessment process, which is industry 
leading practice (see the following page). 
In 2023 we will also formalise our ERM 
continuous improvements with Manage­
ment reports to the Board on ERM action 
plan implementation. 
Dr Gillian Davidson
Chair of the Board Sustainability 
Committee
Companies with good governance 
are more likely to have enhanced 
environmental and social 
practices relative to their peers
Reflecting our commitment to the success­
ful achievement of the growth principle of 
our strategy - with production at Araguaia 
fast approaching and successful funding of 
a feasibility study for Vermelho underway 
– we completed a systematic review of our 
corporate policies. We subsequently en­
dorsed a Horizonte Policy on Security and a 
Policy on Inclusion and Diversity, as well as 
supporting Management’s development of 
a Supplier Code of Conduct, to complement 
our existing Policies. Additional comple­
mentary corporate policies are expected to 
be released in 2023. I will share more de­
tails of these objectives in our 2022 Hori­
zonte Sustainability Report.
As a result of conversations at the World 
Economic Forum (WEF) in 1999, the then 
Secretary-General of the United Nations 
(UN) and Nobel Peace prize laureate, Kofi 
Annan issued a call for a ‘Global compact 
of shared values and principles’ on human 
rights, labour standards, environmental 
practices and anti-corruption. This was 
the genesis of what later became the UN 
Global Compact (UNGC), a movement of 
over 21,000 companies and 162 countries! 
As a former member of the WEF team, I 
have seen first-hand, around the world, 
the significant positive impacts that mining 
companies can bring to host communities 
when aligned to these values, principles 
and the Sustainable Development Goals. 
Horizonte’s efforts in 2022 to commence 
target setting and reporting aligned with 
the UNGC, for a company which had not 
yet even commenced construction, was 
leading practice.
Accompanying the Sustainability Report 
and our reporting on our progress in im­
plementation of the UNGC targets that 
we set for ourselves, will be a significantly 
expanded set of disclosures of our sus­
tainability performance to standards, sup­
porting our transition from developer to 
producer and a demonstration of our com­
mitment to honesty (integrity) and courage 
in our actions. 
Beyond our own work in sustainability gov­
ernance, the Horizonte Board of Directors 
is supported by the work of an independ­
ent, environmental and social consultancy. 
This group conduct quarterly assurance 
reviews of our Araguaia operations to 
monitor conformance to the international 
standards that have been adopted by Hori­
zonte. The outcome of these reviews are 
presented to the Sustainability Committee 
and inform the processes of governance 
that we undertake on behalf of sharehold­
ers and stakeholders.

Chair of the Board Sustainability
Committee
Materiality
Each year we analyse the most impor­
tant sustainability issues for our busi­
ness and stakeholders to inform our 
strategy and focus areas for the up­
coming year. In 2022/3 we enhanced 
this process to reflect the evolution of 
our business. In this more comprehen­
sive process we:
	
~ Identified topics from industry 
and peer bench-marking, 
enterprise risk management 
processes, industry standards, 
ESG rating services and grievance 
mechanisms;
	
~ Undertook a detailed analysis 
of our peer group and their 
published material topics 
assessment;
	
~ Invited a variety of internal and 
external stakeholder to complete 
a materiality survey to indicate to 
us which sustainability topics are 
of most importance;
	
~ Conducted an assessment 
process to identify priorities - 
using weighting to ‘draw out’ 
issues that also intersect with 
our enterprise risk management, 
peer-based norms and industry 
trends; and
	
~ Completed a validation process 
with executive and sustainability 
specialised Board members.

The Board and its Committees are mindful 
of the potential impact of decisions on 
relevant stakeholders whilst also having 
regard to a number of broader factors, 
including the need to foster the Compa­
ny’s business relationships with suppliers, 
customers and others. Particular con­
sideration is given to the impact of the 
Company’s projects on the community 
and environment, responsible business 
practices and the likely consequences of 
principal Board decisions in the long term. 
The Company, its Board of Directors and 
Company management are fully commit­
ted to effectively engaging with all key 
stakeholders.
All members of the Board of Directors 
understand the duties as directors un­
der Section 172 of the Companies Act 
2006. We are committed to fostering 
strong relationships with our stake­
holders through purposeful engage­
ment, and value creation, with fair and 
thoughtful consideration of stakehold­
er perspectives within our strategic 
decisions. We recognise that we can 
only achieve long-term success by con­
sidering how our projects affect stake­
holders such as communities and the 
environment, supported by a strong 
ethics culture.  
Responsibility for stakeholder engage­
ment is embedded across the business, 
from the Board to the Executive Com­
mittee and site leadership teams, to 
our community liaison teams and our 
contractors. Everyone who interacts 
with Horizonte’s employees, inves­
tors, lending banks, national or local 
government, suppliers and host com­
munities is responsible for ensuring 
that we not only understand the con­
text and impacts of our operations, but 
also the benefits that can arise from 
our activities.
Our stakeholders
 
We identify our relevant stakeholders 
on the right by considering their influ­
ence on the success of our business 
model and strategy. Here we explain the 
importance of engagement, how we do 
it, significant topics raised, Horizonte’s 
responses and the actions the Compa­
ny has undertaken. In our ‘Managing 
Our Risks and Opportunities’ section 
on pages 34-41, we evaluate the risks 
associated with these relationships and 
the strategies we use to mitigate them.

Importance of 
engaging
At Horizonte, we believe that our 
employees are the cornerstone of 
our business and that a partnership 
approach is vital to achieving busi­
ness objectives. We provide compet­
itive remuneration and invest in pro­
fessional and personal development 
while providing an engaging, safe 
and healthy working environment.
Trust, understanding and cooperation 
with the communities that surround 
our projects are critical to maintaining 
our social licence to operate. Com­
munity engagement informs better 
decision making and aligns interests 
to ensure the long-term success 
of our projects.
Our shareholders are Horizonte’s owners 
and their continued support is critical to 
the business. As we seek to develop a 
sustainable mining company for the long-
term, they provide the capital to develop 
and build our operations responsibly and 
sustainably and consequently, we need 
to ensure we continue to deliver a com­
pelling investor proposition.  
Building stable, long-term relationships 
based on mutually beneficial terms with 
our suppliers and contractors ensures we 
are not only able to deliver our projects on 
time and on budget, but is also critical in 
maintaining our reputation. It is integral 
to business success that we work in col­
laboration with the whole value chain, as 
we strive for compliance with our ethical, 
environmental and safety standards.  
Horizonte complies with laws and 
regulations applicable to it and we are 
focused on ensuring Brazil shares in 
the benefits of our Projects through 
the creation of long-term value 
creation. The ongoing support from all 
government bodies and civil society 
is critical to this development and 
we value the importance of working 
collaboratively and productively with 
all relevant entities.

MANAGING 
OUR RISKS AND 
OPPORTUNITIES
A key accountability and authority of 
the Horizonte Board of Directors is de­
fining the boundaries of risk tolerance 
and appetite within the business, to 
drive alignment to the company values, 
ethics and business conduct standards. 
The Horizonte risk management system 
operationalises the processes of Board 
input and oversight into the manage­
ment of risk, as well as the mechanisms 
by which the Executive Management 
determine materiality.
The risk management system, aligned 
to ISO  31000, is designed to achieve 
the following:
	
~ Board visibility on material risks.
	
~ Personnel understand their 
accountabilities and authorities in 
relation to risk, including:
•	 Any Horizonte team member 
may stop an activity that they 
consider presents a threat of loss 
of life, loss of human rights and/or 
loss of protected environmental, 
cultural or social values.
•	 Only the CEO has the authority to 
approve activity with a residual 
(after controls) ‘catastrophic’ 
level of risk.










	
~ Executive Management are 
accountable to identify, assess 
and manage strategic risks, 
including cumulative, emerging and 
evolving risks, as well as those of a 
tactical nature.
To deliver these objectives, the risk 
management system comprises:
	
~ Enterprise Risk Management – the 
process by which the Board and 
Management identify and manage 
Horizonte’s strategic risk universe.
	
~ Materiality assessment - the 
process through which the Board, 
Management, specialists and key 
external stakeholders identify and 
manage material sustainability 
risks and associated governance 
related disclosures.
	
~ A risk matrix to ensure consistency in 
risk assessment across the company.
	
~ Project pipeline risk identification, 
assessment and management 
processes including due diligence, 
impact assessments and 
related analysis.
	
~ Business unit (Araguaia, Vermelho) 
level risk identification, assessment 
and management processes 
including the documentation of 
risk registers.
In undertaking the Horizonte enterprise 
risk management process to identify and 
assess the prevailing risk universe, the 
company reviews industry trends, peer 
group benchmarks, market analysis and 
business unit risk registers. 
RISK  FACTORS
In accordance with disclosure and trans­
parency laws, the company is required to 
provide a description of the material ad­
verse risks and uncertainties that it faces. 
These risks are similar to those faced by 
many companies in the mining industry 
and specifically companies in the opera­
tional development phase. 
A description of such risks and uncertain­
ties, as well as mitigating factors and con­
trols applied by Horizonte, are documented 
in the following table. 
This table is not prioritised list, nor is it ex­
haustive. It is rather the Board’s view of 
principal risks at this point in time. There 
are additional risks which are not yet 
considered material or which are not yet 
known to the Board or fully understood 
but which may assume greater importance 
in the future. 
Nature of risk
Management 
and Mitigation
The value of the Company's assets, potential earnings or viability 
of projects may be affected by fluctuations in commodity prices, 
such as the US$ denominated nickel and cobalt prices. Commodity 
prices can significantly fluctuate and are exposed to numerous 
factors beyond the control of the Company such as world demand 
for base metals, forward selling by producers, and production cost 
levels in major metal producing regions. Other factors that can 
affect commodity prices include expectations regarding inflation, 
the financial impact of movements in interest rates, global, regional 
and local economic trends, and domestic and international fiscal, 
monetary and regulatory policy settings.

Nature of risk
Management 
and Mitigation
It is not uncommon for new mining developments to experience 
unexpected problems, increased costs and delays during 
construction, commissioning and production start-up, or indeed 
for such projects to fail. Any adverse event affecting Horizonte’s 
projects, either during their development or following the 
commencement of production, would have a material adverse 
effect on the Company’s business, results of operations, financial 
condition and the price of its Ordinary Shares.
	
~ Project execution planning and monitoring 
by Management with the support of 
specialist Technical Committees and 
independent third parties
	
~ US$400m of key contracts awarded as

Nature of risk
Management 
and Mitigation
Horizonte is committed to building and operating our projects in a 
safe and responsible manner. At both a local and a global level, the 
mining industry’s stakeholders have high expectations relating to 
social and environmental performance. These expectations go be­
yond the responsible management of negative impacts, to include 
continuous engagement and meaningful contribution to stake­
holder economic development. Failure to adequately address these 
expectations increases the risk of opposition to mining projects 
and operations. Negative sentiment towards mining or specifically 
towards Horizonte Minerals plc could have an impact on our repu­
tation and acceptability in the regions where we have a presence. 
Legal or administrative proceedings, civil unrest, protests, direct 
action or campaigns against us could materially and adversely af­
fect our business, financial condition or project development.

Nature of risk
Management 
and Mitigation
The mining industry frequently engages specialist EPCM contrac­
tors to deliver major project construction. Horizonte is working 
with EPC teams for the construction of its Araguaia project. The 
outsourced nature of these activities means that the perfor­
mance of such contractors and suppliers can impact project 
deliverables. Performance issues by contractors or misalignment 
in goals may manifest as delays to the construction programme 
schedule, unanticipated costs being incurred, and/or in plant and 
equipment performance in commissioning or operations.

Horizonte’s current and future operations require approvals and 
permits from various federal, state and local governmental au­
thorities, and such operations are and will continue to be gov­
erned by laws and regulations governing prospecting, develop­
ment, mining, production, taxes, labour standards, health, waste 
disposal, toxic substances, land use, environmental protection, 
mine safety and other matters. There can be no assurance that 
the group will obtain required permits on reasonable terms or on 
a timely basis, nor that delays will not occur in connection with 
obtaining, maintaining or renewing any approvals or permits nec­
essary for the business.

Liquidity, access to capital and debt covenants
Nature of risk
Management 
and Mitigation
Pre-revenue mining companies are typically reliant on external 
funding to provide the required liquidity to operate and to un­
dertake project development activities.  The inability to obtain 
external funding of a sufficient quantum that allows project 
development to be completed and production to generate positive 
operating cash flows, presents the risk that the developer would 
not be able to continue to operate.  External funding when se­
cured is contingent upon conformance to highly detailed, prescrip­
tive and sometimes onerous conditions. The ability to conform to 
these conditions may be affected by inputs outside of the bor­
rower’s control, which could lead to breach of debt covenants and 
related impacts.

Nature of risk
Management

The development and success of a mine developer depends on 
the ability to recruit and retain high quality and experienced staff, 
reflecting the various skills and competencies needed for the 
phases of evolution of the business. The loss of service of key 
personnel or the inability to attract additional qualified person­
nel at key points in the business growth, could have an adverse 
effect on financial conditions and business delivery. Horizonte 
has traditionally operated with a small number of key individuals, 
in particular its senior Management, reflecting the pre-revenue 
nature of the business. Talent management processes, such as 
succession planning, attractive incentive plans comprising both 
short and long term elements, and contractual agreements aim to 
secure and retain the services of these and other key personnel, 
however, the retention of their services cannot be guaranteed.

It is an inherent risk in the mining industry, that incidents due to 
unsafe acts or conditions, or the failure of equipment or infra­
structure could lead to injuries or fatalities. Safety and health 
incidents could result in harm to employees, contractors and local 
communities. Within Horizonte’s workplaces people will work 
with materials that are potentially explosive, or hazardous, they 
may work with electricity, heavy equipment and machinery and at 
heights, as well as being exposed to other occupational exposures. 
Ensuring the safety and wellbeing of people in the workplace is 
both an ethical obligation and regulatory requirement, and failure 
to do so can impact lives, maintain licence to operate, ability to 
attract and retain talent and can affect the company reputation 
and share price.

Accuracy of resource estimates
Nature of risk
Management 
and Mitigation
There are numerous uncertainties inherent in estimating mineral 
reserves and resources, including many factors beyond Horizon­
te’s control. The accuracy of these estimates is a function of the 
quantity and quality of available data, orebody characteristics and 
assumptions and judgments used in engineering and geological 
interpretation, which could prove to be unreliable, thereby af­
fecting estimate accuracy, and ability to mine or process profit­
ably or at all.
Fluctuations in metal prices, results of drilling, metallurgical test­
ing, changes in operating costs, production, and the evaluation of 
mine plans subsequent to the date of any estimate could require 
a revision of the estimates. The volume and grade of material 
mined and processed, and recovery rates, might not be the same 
as currently anticipated. Any material reductions in estimates of 
the Company’s reserves and resources, or of its ability to extract 
these, could have a material adverse effect on its results of oper­
ations and financial conditions.

Climate and Decarbonisation
Nature of risk
Management

Nickel has a critical role to play in the transition to a low car­
bon economy, as a primary component of materials used in the 
construction of solar, wind and hydro power generation, as well 
as being a key component of electric batteries and stainless steel. 
Mining operations themselves are reliant on energy and other 
natural resources and typically result in the production of green­
house gases. Physical risks, such as extreme weather events 
and transition risks, such as changes in legislation resulting from 
global community expectation, may also impact the industry and 
markets.

As a modern mining company, Horizonte has and will deploy tech­
nologically advanced, automated systems and processes. This is 
possible as a result of the use of advanced information systems, 
data platforms, technologies and global systems, each of which 
may be exposed to risk of failure or sabotage or which may be 
used as an avenue for illicitly obtaining intellectual property or oth­
er commercially sensitive information. Such failures or sabotage 
could lead to disruption to critical business systems, loss or theft 
of confidential information, competitive advantage, or intellectual 
property, financial and/or reputational harm.

and Mitigation
Horizonte has operated in Brazil for over a 
decade where there has been a stable operating 
regime for mining; however, it remains subject 
to risks similar to those prevailing in many 
developing nations, including economic and 
social instability, changing regulatory or tax 
regime or disputes with the authorities in 
relation to the same. These risks may cause 
disruption to the Company or cause an 
increase in costs in order to mitigate their 
impact; for example a potential increases 
in taxes could have an adverse effect on the 
Group’s financial results.
	
~ Maintain a positive working relationship with all levels of 
Government through dialogue
	
~ Continue to collaborate with other members of the mining 
community through IBRAM, the Brazilian mining chamber, to 
lobby against any potential legislative changes that may have a

NOTE FROM 
THE CHAIR
Our governance structure 
supports our business model 
to ensure we create long-term 
value for all our stakeholders
The Board believes in the value of good 
corporate 
governance 
in 
improving 
performance and mitigating risk and 
acknowledges its duty to take into account 
all 
stakeholders 
during 
its 
decision-
making process. The Board is committed 
to ensuring the sustainability of its 
development strategy and to delivering 
on its commitments to shareholders, 
clients, employees, partners and other 
stakeholders with sustainability in mind.
We 
believe 
that 
transparency 
and 
fair dealing, particularly in relation to 
environmental and community issues, are 
essential in achieving the medium to long-
term success of the Company. As part of 
securing the senior debt funding package, 
Horizonte undertakes quarterly reviews 
across a wide variety of topics using an 
independent third party. These include, 
but not limited to, Project execution, 
expenditure and ESG related topics.
Horizonte’s primary listing is on the AIM 
Market of the London Stock Exchange 
(AIM). The Company abides by the AIM 
Rule 26 regulation in respect to reporting 
and has therefore chosen to adhere to 
the Quoted Company Alliance’s (QCA) 
Corporate Governance Code for Small and 
Mid-Size Quoted Companies. 
In Brazil the Company has been a member 
of the Brazilian Association of Mineral 
Exploration Companies (ABPM) since 2013 
and in 2020 it became a member of the 
Brazilian Mining Institute (IBRAM). 
Creating a culture of good governance is 
led from the top, by Horizonte’s Board, 
and is cultivated in every part of the 
organisation. Evolving the Company’s 
corporate governance is a key part of the 
Company’s transition. We have therefore 
committed to a corporate governance 
review and will be reporting on subsequent 
changes in 2023 and beyond.

The Board considers that there is an 
appropriate 
balance 
between 
the 
Executives and Non-executives (both 
independent and non-independent) and 
that no individual or small group dominates 
the Board’s decision making.  
The Board has reserved the following 
matters for sole approval by the Board:
	
~ Review and approval of the Company’s 
strategic plan
	
~ Review and approval of the annual 
operating plan and financial budget, 
including any changes during the year
	
~ Review and approval of the Annual 
Report, financial statements, MD&A 
and quarterly financial statements. 
These documents are also reviewed and 
approved by the Audit & Risk Committee
	
~ Establishment of expenditure limits and 
approval of exceptions
	
~ Hiring, review and compensation of CEO 
and CFO (following recommendation 
from the Remuneration Committee)
	
~ Director recruitment
	
~ Appointment of Chair
	
~ Appointment of Committee Chair and 
Committee members
The Company has a policy on share 
dealing and confidentiality of inside 
information 
for 
persons 
discharging 
managerial responsibilities and persons 
closely associated with them, which 
contains provisions appropriate for a 
company whose shares are admitted 
to trading on AIM (particularly relating 
to 
dealing 
during 
close 
periods 
in 
accordance with Rule 21 of the AIM Rules 
and MAR) and the Company takes all 
reasonable steps to ensure compliance 
by the persons governed by such policy. 

The Board continues to monitor its 
governance framework on an ongoing basis. 
Board
The Board of Horizonte is responsible 
for setting the vision and strategy for 
the Company to deliver value to all 
stakeholders by effectively putting in 
place its business model. 
Chair
The primary responsibility of the Chair is to 
lead the Board effectively and to oversee 
the adoption, delivery and communication 
of the Company’s corporate governance 
model. The chair has adequate separation 
from the day-to-day business to be able 
to make independent decisions. Save 
in exceptional (and well justified and 
explained) 
circumstances, 
the 
Chair 
should not also fulfil the role of Chief 
Executive Officer. 
CEO
The Company’s CEO is charged with the 
delivery of the business model within 
the strategy set by the Board. The CEO 
works with the Chair and NEDs in an open 
and transparent way and keeps the chair 
and NEDs up-to-date with operational 
performance, risks and other issues to 
ensure that the business remains aligned 
with the strategy. 
Non-Executive Directors
The Company’s NEDs participate in all 
board level decisions and play a particular 
role in the determination and articulation 
of strategy. The Company’s NEDs provide 
oversight and scrutiny of the performance 
of the executive directors, whilst both 
constructively challenging and inspiring 
them, thereby ensuring the business 
develops, communicates and executes 
the agreed strategy and operates within 
the risk management framework. 
Remuneration Committee
The remuneration committee comprises 
William Fisher (Chair), Owen Bavinton 
and Vincent Benoit and is responsible 
for 
reviewing 
the 
performance 
of 
the 
Executive 
Director 
and 
senior 
management, 
and 
for 
setting 
the 
framework and broad policy for the scale 
and structure of their remuneration, 
taking into account all factors which it 
shall deem necessary. The remuneration 
committee 
also 
recommends 
the 
allocation of share options for the Board 
to approve and is responsible for setting 
up any performance criteria in relation 
to the exercise of options granted under 
any share options schemes adopted 
by the Group. 
Audit Committee
The audit committee, comprising Vincent 
Benoit (Chair), William Fisher and Gillian 
Davidson, has primary responsibility for 
monitoring the quality of internal controls, 
ensuring that the financial performance 
of the Group is properly measured and 
reported on and for reviewing reports 
from the Group’s auditors relating to the 
Group’s accounting and internal controls. 
Nomination Committee
In December 2021, the company estab­
lished a formal nomination committee 
comprising Jeremy Martin (Chair), Owen 
Bavinton and William Fisher. The com­
mittee is responsible for finding and as­
sessing appropriate candidates for the 
Board in line with the company’s evolving 
required skillset of mine building and pro­
duction. The committee will also develop 
a formal succession plan. 
Sustainability & ESG
In April 2022, the Company established a 
formal Sustainability and ESG Committee 
initially comprising Dr Gillian Davidson 
(Chair) and Dr Owen Bavinton. The 
committee is responsible for assisting 
the Board in maintaining healthy and safe 
workplaces, environmentally sound and 
responsible resource development, good 
community relations and the protection of 
human rights; promoting the appropriate 
culture, behaviours and actions in relation 
to these matters; and communicating the 
Board’s commitment to these matters to 
the Group’s employees, contractors and 
other stakeholders

BOARD 
REPORTS
Board Composition
The Board comprises a group of experienced 
Directors with a diverse skillset relevant 
to the development of a mining company. 
Each Director has a wealth of experience 
and depth of knowledge in the mining 
industry 
and 
complementary 
fields 
including law, business development and 
capital markets. This diversity of skills and 
experience across multiple jurisdictions 
and 
professional 
disciplines 
provides 
the Company with effective leadership 
and direction. Each Director keeps their 
skillset up to date through a combination 
of continual professional development and 
attendance at seminars and conferences 
relevant 
for 
the 
industry 
Horizonte 
operates in. All Directors retire on rotation 
at regular intervals in accordance with the 
Company’s Articles of Association.
We understand the importance of an in­
dependent board and this independence 
is constantly reviewed. Dr Owen Bavinton, 
Dr Gillian Davidson and Mr William Fisher 
are each considered an independent di­
rector since they are each independent 
of management and free from any ma­
terial relationship with the Company. The 
basis for this determination is that, de­
spite their tenures on the board, since 
17 January 2012 and 7 June 2011 respec­
tively, Dr Owen Bavinton and Mr William 
Fisher have not worked for the Company, 
received remuneration from the Company 
or had material contracts with or materi­
al interests in the Company which could 
interfere with their ability to act with a 
view to the best interests of the Company. 
Dr Gillian Davidson was appointed to the 
Board on 24 March 2022 and has no direct 
or indirect material relationship with the 
Company. The Board continually assesses 
the independence of its directors, the com­
position and effectiveness of the Board as 
a whole and is actively considering supple­
menting the Board with additional inde­
pendent non-executive directors in 2023 
as the Company transitions to become a 
producing nickel company.
Each of Messrs Vincent Benoit and 
Jeremy Martin are considered to be non-
independent directors as a result of their 
respective relationship with the Company.
The Board maintains the exercise of inde­
pendent supervision over management by 
encouraging open and candid discussion 
from its independent directors. In addition, 
although Mr Vincent Benoit is not consid­
ered to be independent, the Board does 
not view this relationship as impairing the 
ability of the Board to act independently of 
management.

Board changes
As part of the ongoing succession planning 
for the Board, and as mentioned in the 
Chair’s letter, David Hall stepped down as 
Chair of the Board during 2022. Sepanta 
Dorri and Allan Walker both stepped down 
from the Board at the 2022 AGM. Dr Gillian 
Davidson and Vincent Benoit both joined 
the Board in March 2022.
Board diversity
We continue to recognise and embrace the 
benefits of having a diverse Board; particu­
larly the value that different perspectives 
and experience bring to the quality of Board 
debate and decision-making. We hold fast 
to the importance of making Board ap­
pointments on the basis of merit; but we 
also take seriously considerations such as 
background and experience, age, gender, 
and shareholder perspectives in our re­
views of the composition of the Board. We 
believe that setting targets for the number 
of people from a particular background or 
gender is not an effective approach and 
therefore we have no specific quotas or 
targets. Nevertheless, currently the Board 
believes that continuity of Board members 
and familiarity with the Araguaia Project 
are critical to the Company at its stage in 
its development. The Board intends to 
consider whether it should adopt specific 
policies and practices regarding the rep­
resentation of women on the Board and in 
executive positions, including the setting of 
targets for such representation at such a 
time as the Corporation moves beyond its 
development stage into production.
Board Changes and Nominations
The Company’s Nomination Committee has 
assumed responsibility for the recommen­
dation for appointment and assessment of 
directors. While there are no specific crite­
ria for Board membership, the Company 
attempts to attract and maintain directors 
with business knowledge and a particular 
knowledge of mining, mineral exploration 
and development or other areas (such 
as accounting or finance) which provide 
knowledge which would assist in providing 
guidance to the officers of the Company. 
As such, nominations tend to be the re­
sult of recruitment efforts and discussions 
amongst the Nomination Committee and 
the Chief Executive Officer prior to the con­
sideration of the Board as a whole.

The audit committee meets quarterly dur­
ing the year to consider the Audit planning 
report and Audit completion report pre­
sented by the auditors regarding the year 
end audit process. The year end audit find­
ings were focused on the key areas identi­
fied during the planning process, the main 
items being: 
	
~ Internal controls and man­
agement override 
	
~ Carrying value and impairment 
of intangible exploration and 
evaluation assets 
	
~ Carrying value of investment in sub­
sidiaries and intercompany loans
	
~ Convertible loan note accounting 
and valuation
	
~ Accounting treatment of FEC hedges
	
~ Senior debt facility accounting treat­
ment and valuation
	
~ Accounting for the royalty 
finance agreement 
	
~ Assessment recognition of contin­
gent consolidation 
	
~ Going concern 
The audit committee were in agreement 
with all the findings and recommendations. 
The remuneration committee met twice 
during the year to consider the remuner­
ation levels of the board and key officers 
of the company, to consider and approve 
the basis of the long-term incentive plan 
and to consider and award options to key 
members of the team.
Evaluating Board Performance
In accordance with best practice and the 
Code, the Board undertakes an annual 
formal evaluation of its performance and 
effectiveness, and that of each Director 
and Committee. This evaluation is con­
ducted by way of a questionnaire from 
the Chair, co-ordinated by the Company 
Secretary and concluded by Chair inter­
views where necessary. In addition, the 
Non-Executive Directors met, informally, 
without the Chair present and evaluat­
ed his performance. The Board currently 
considers that the use of external con­
sultants to facilitate the Board evalua­
tion process is unlikely to be of signifi­
cant benefit to the process, although the 
option of doing so is kept under review. 
The Chair has stated that he values this 
annual evaluation opportunity and con­
siders it to be key to his role in creating an 
effective Board. 
He has reported that the Board was satis­
fied that the Board was effective and well 
run, there were therefore no recommen­
dations and none in the prior year. 
The remuneration is determined in ac­
cordance with the Articles of Association. 
When determining executive director 
remuneration policy and practices, the 
Company’s remuneration committee ad­
dresses the following: 
	
~ Clarity – remuneration arrange­
ments are transparent and promote 
effective engagement with share­
holders and the workforce
	
~ Simplicity – remuneration structures 
avoid complexity and their rationale 
and operation are easy to understand 
	
~ Risk – remuneration arrangements 
ensure reputational and other 
risks from excessive rewards, and 
behavioural risks that can arise from 
target-based incentive plans, are 
identified and mitigated
	
~ Proportionality – the link between 
individual awards, the delivery of 
strategy and the long-term per­
formance of the Group should be 
clear. Outcomes do not reward poor 
performance
	
~ Alignment to culture – incentive 
schemes drive behaviours con­
sistent with company purpose, 
values and strategy. 
Support to Directors
The Board has the full support of the Com­
pany secretary.
The Board receives regular and timely infor­
mation of the Company’s operational and 
financial performance in order to perform 
this function. Relevant, detailed informa­
tion is circulated to all Directors ahead of 
Board and Committee meetings. The Com­
pany Secretary is responsible for keeping 
the Board up to date on its responsibilities 
in compliance with relevant regulations.
The Board and Culture
The Board believes that the promotion 
of a corporate culture based on sound 
ethical values and behaviours is essen­
tial to maximising shareholder value.

Horizonte’s company culture is consistent 
with its objectives, strategy and business 
model. The Board regularly meets and 
monitors the business and its stakehold­
ers to ensure the values and strategy are 
aligned with the company’s internal culture. 
The Directors act with integrity, lead by ex­
ample, and promote the desired culture.

We believe that transparency and ethical 
behaviour are central to any successful 
company and undertake all development 
with respect to the environment and 
neighbouring communities.
Shareholder Engagement
The Board attaches great importance to 
providing shareholders with clear and 
transparent information on the Company’s 
activities, strategy and financial position. 
Communication with all shareholders 
is predominately led by the CEO, CFO 
and Head of Investor Relations, but 
the Chair and non-executive directors 
provide additional points of contact 
for shareholders, particularly at the 
Company’s AGM. We value the views 
and feedback of our shareholders and 
these are often discussed as a collective 
during board meetings, no significant 
actions or feedback were reported during 
the year. Further information on our 
shareholder engagement can be found in 
the stakeholder engagement section on 
pages 32-33. 
Material information in relation to the 
Company is made publicly available via 
the London Stock Exchange’s Regulatory 
News Service (RNS) and via the System for 
Electronic Document Analysis and retrieval 
(SEDAR) in Canada. 
Details of our shareholder engagement 
during the year can be found in the follow­

AUDIT AND RISK 
COMMITTEE 
REPORT
REMUNERATION 
COMMITTEE 
REPORT
The Audit and Risk Committee currently 
comprises Vincent Benoit (Chair), Gillian 
Davidson and William Fisher. The Audit 
and Risk Committee met five times during 
the year. 
The Auditors have unrestricted access to 
the Chair of the Audit and Risk Committee. 
Audit and Risk Committee meetings are 
usually attended by the Auditor and, by 
invitation, senior management. 
The main responsibilities of the Audit and 
Risk Committee include: 
	
~ Monitoring the integrity of the 
Group’s financial statements, 
including review of the financial 
statements of the Company including 
its annual and half-yearly reports 
and any formal announcements 
relating to its financial performance; 
	
~ Reviewing the effectiveness of the 
Group’s financial reporting, internal 
control policies and procedures for 
the identification, assessment and 
reporting of risk; 
	
~ Monitoring the effectiveness of the 
internal control environment; 
	
~ Making recommendations to the 
Board on the appointment of the 
Auditors; 
	
~ Making a recommendation to the 
Board on Auditors’ fees; 
	
~ Agreeing the scope of the Auditors’ 
annual audit programme and 
reviewing the output; 
	
~ Ensuring the independence of the 
Auditors is maintained; 
	
~ Assessing the effectiveness of the 
audit process; and 
	
~ Developing and implementing policy 
on the engagement of the Auditors 
to supply non-audit services. 

The Audit and Risk Committee has consid­
ered the Group’s internal control and risk 
management policies and systems, their 
effectiveness and the requirements for 
an internal audit function in the context 
of the Group’s overall risk management 
system. 
The Committee is satisfied that the Group 
does not currently require an internal au­
dit function; however, it will continue to 
periodically review the situation. An es­
sential part of the integrity of the financial 
statements lies around the key assump­
tions and estimates or judgments to be 
made. The Committee reviewed and was 
satisfied that the judgements exercised 
by management contained within the 
Report and Financial Statements are rea­
sonable. 
Details of fees payable to the Auditors are 
set out in Note 7.

Long Term Incentive Plan (“LTIP”)
In 2019 the Company put in place a Long-Term Incentive Plan (‘LTIP’) for the purpose of incentivising, motivating and rewarding cer­
tain employees in respect of their contributions to the Company’s mid and long-term commercial objectives designed to create value 
for shareholders. The performance conditions are based upon major project milestones delivered across the Company’s two projects; 
Araguaia and Vermelho.
The agreements for members include four performance conditions. The amount of any bonus payment shall be determined by the 
performance conditions set out in the applicable bonus agreement for each individual participant.
The performance conditions are:
1.	Completion of a comprehensive bankable feasibility study for each Project (‘Feasibility Study’);
2.	Securing full project finance to construct either Project (‘Securing Project Finance’);
3.	The first commercial production of each Project (‘First Commercial Production’); and
4.	The sale of any interest in either Project or a specified percentage of the share capital of the Company (‘Sale’).
Both the CEO and the CFO are eligible for certain bonuses upon reaching certain operational milestones which are deemed to be 
aligned with shareholder value enhancing points in the development pathway of both the Araguaia and Vermelho projects. They are 
eligible for a fee of 0.475% of gross funds raised with certain Non-Executive Directors receiving Bonuses of £200,000 upon securing 
Project Financing. 
In 2021 the company secured a project finance package to fully fund the Araguaia project through construction therefore triggering 
one of the key performance conditions of the LTIP. The bonuses paid in 2021 to the CEO & CFO represent those due upon the settle­
ment of the equity portion of the project finance which was closed in 2021. The LTIP bonuses paid in cash during the year to the CEO 
and CFO represent those due upon the settlement of the convertible loan notes, cost overrun facility and the Vermelho Royalty which 
was closed in 2022. The non-executive directors that stepped down as directors during the year received the balance of their LTIP 
bonus.  All awards due for the senior debt portion of the project finance package including 50% of any awards due to certain Non-Ex­
ecutive Directors have been deferred until the second draw down of the senior debt facility at which time the award will be paid in 
full to those eligible. The award has been deferred in order to align with value creation for the shareholders. The CEO and CFO will be 
eligible for a fee of 0.475% of the senior debt facility of US$346.2million.

HORIZONTE MINERALS 2022 ANNUAL REPORT
HORIZONTE MINERALS 2022 ANNUAL REPORT
DIRECTORS’ 
REPORT
The Directors present their Annual 
Report on the affairs of Horizonte 
Minerals Plc, together with the audited 
Financial Statements for the year ended 
31 December 2022. 
Principal activities 
The principal activity of the Group and 
Company is the identification, acquisition, 
exploration and development of mineral 
projects. The main area of activity 
comprises the development of the 
Araguaia and Vermelho nickel projects, 
located in Pará State in north-eastern 
Brazil. 
Financial results and dividends
The Group results for the year are set 
out on page 64. The Group is currently 
involved in exploration, evaluation and 
development activities and not actively 
mining. As a result, the Group is not 
revenue generative. 
During the year the Group made good 
progress on the construction of the 
Araguaia Nickel Project which remains 
on-budget and on-schedule to commence 
production in Q1-2024. The Group has 
also advanced the permitting process 
for the Vermelho Nickel Cobalt Project 
in parallel with ongoing work on the 
Feasibility Study which is expected to be 
published in H1-2024.
In October 2022 the Group conducted a 
further fundraising (the Fundraise) and 
raised gross proceeds of ~ US$80 million. 
Although the development of Araguaia 
was running to schedule and a number of 
key milestones achieved, in light of global 
inflationary pressures and engineering 
improvements to de-risk the project the 
total capital cost for Araguaia is forecast to 
be US$537 million versus US$477million. 
The Fundraise is anticipated to allow the 
Group to complete the construction of 
the Project. In addition, the Fundraise will 
allow the Group to accelerate engineering 
studies and basic engineering for the 
development of line 2 at Araguaia, as well 
as further invest in its decarbonisation 
strategy for the Project.
On 7 December 2022, the Group satisfied 
all conditions precedent for the first 
utilisation under the senior debt facility 
of US$346.2 million. The first utilisation 
was for US$5million. In addition the Group 
also satisfied all conditions precedent in 
relation to the cost overrun facility (COF) 
and received all COF funds from Orion.
The Directors do not recommend payment 
of a dividend (2020: £Nil).
Sustainability
Details of the Company’s approach and 
activities in relation to sustainability can 
be found on pages 26-31 of the Strategic 
Report included within this Annual Report 
and in a standalone Sustainability Report 
available on the Company’s website 
www.horizonteminerals.com. 
While there is no requirement to publish 
information under SECR in 2022, this 
will be reviewed and it is the intention 
of the Company to comply with the 
reporting disclosures next year in line 
with best practice.  
Share Capital
Changes in the share capital of the Com­
pany are set out in note 15 of the Finan­
cial Statements.
Directors’ statement as to 
disclosure of information to auditor
The Directors who held office at the date of 
approval of this Directors’ Report confirm 
that, so far as they are individually aware, 
there is no relevant audit information of 
which the Company’s auditor is unaware 
and the Directors have taken all the steps 
that they ought to have taken to make 
themselves aware of any relevant audit 
information and to establish that the 
auditor is aware of the information.
Matters covered in the 
Business Review 
The business review and review of KPIs 
are included in the Operations Review and 
Strategic Report. 
Financial risk management 
The Company is exposed through its 
operations to the following financial risks: 
	
~ Commodity price risk
	
~ Foreign currency risk
	
~ Credit risk 
	
~ Interest rate risk 
	
~ Liquidity risk 
The group undertakes certain policies 
and procedures to mitigate these risks as 
much as is practicable, including hedging 
foreign exchange movements, only using 
credit worthy financial institutions and 
using short term deposits to manage 
interest rate and liquidity risks. As the 
Group moves towards being a producing 
entity it will continually review these 
risk mitigation policies to cover off 
any potential exposure to commodity 
prices 
and 
increase 
exposure 
to 
foreign exchange risks. 
In common with all other businesses, the 
Group is exposed to financial risks that 
arise from its operations, these along 
with managements’ policies surrounding 
financial risk management are explained 
in note 3 to the financial statements.
Events after the reporting date 
The events after the reporting date are set 
out in note 38 to the Financial Statements. 
Future developments 
In 2023 the Group will be working towards 
constructing and bringing the Araguaia 
project 
into 
commercial 
production. 
Having published a Pre-Feasibility Study 
on the Vermelho project during 2019, the 
Group is focused on further advancing the 
VNCP project towards a Feasibility Study 
and eventual construction decision.  
Directors and Officers Insurance 
The Group provided Directors and 
Officers insurance for both the current 
and prior periods. 
Annual General Meeting 
The Notice of the Annual General Meeting 
of the Company and the Management 
Information 
Circular

HORIZONTE MINERALS 2022 ANNUAL REPORT
STATEMENT 
OF DIRECTORS’ 
RESPONSIBILITIES	
The directors are responsible for prepar­
ing the annual report and the financial 
statements in accordance with applicable 
law and regulations. 
Company law requires the directors to 
prepare financial statements for each fi­
nancial year.  Under that law the directors 
have elected to prepare the group and 
company financial statements in accord­
ance with UK adopted international ac­
counting standards.  Under company law 
the directors must not approve the finan­
cial statements unless they are satisfied 
that they give a true and fair view of the 
state of affairs of the group and company 
and of the profit or loss of the group and 
company for that period.  
In preparing these financial statements, 
the directors are required to:
	
~ select suitable accounting policies 
and then apply them consistently;
	
~ make judgements and accounting 
estimates that are reasonable and 
prudent;
	
~ state whether they have been 
prepared in accordance with UK 
adopted international accounting 
standards subject to any material 
departures disclosed and explained 
in the financial statements;
	
~ prepare the financial statements on 
the going concern basis unless it is 
inappropriate to presume that the 
group and the company will continue 
in business.
The directors are responsible for keep­
ing adequate accounting records that are 
sufficient to show and explain the compa­
ny’s transactions and disclose with rea­
sonable accuracy at any time the finan­
cial position of the company and enable 
them to ensure that the financial state­
ments comply with the requirements of 
the Companies Act 2006.  They are also 
responsible for safeguarding the assets 
of the company and hence for taking rea­
sonable steps for the prevention and de­
tection of fraud and other irregularities.
Website publication
The directors are responsible for ensuring 
the annual report and the financial state­
ments are made available on a website. 
Financial statements are published on the 
company’s website in accordance with 
legislation in the United Kingdom gov­
erning the preparation and dissemination 
of financial statements, which may vary 
from legislation in other jurisdictions.  The 
maintenance and integrity of the compa­
ny’s website is the responsibility of the di­
rectors.  The directors’ responsibility also 
extends to the ongoing integrity of the fi­
nancial statements contained therein.
Opinion on the financial statements
In our opinion:
	
~ the financial statements give a true and fair view of the state of the Group’s and of the Parent Company’s affairs as at 31 
December 2022 and of the Group’s loss for the year then ended;
	
~ the Group financial statements have been properly prepared in accordance with UK adopted international 
accounting standards;
	
~ the Parent Company financial statements have been properly prepared in accordance with UK adopted international accounting 
standards and as applied in accordance with the provisions of the Companies Act 2006; and
	
~ the financial statements have been prepared in accordance with the requirements of the Companies Act 2006.
We have audited the financial statements of Horizonte Minerals PLC (the ‘Parent Company’) and its subsidiaries (the ‘Group’) for the 
year ended 31 December 2022 which comprise of the Consolidated Statement of Comprehensive Income, the Consolidated Statement 
of Financial Position, the Company Statement of Financial Position, the Consolidated Statement of Changes in Equity, the Company 
Statement of Changes in Equity, the Consolidated Statement of Cash Flows, the Company Statement of Cash Flowsand 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 UK adopted International 
Accounting Standards and, as regards to the Parent Company financial statements, as applied in accordance with the provisions of the 
Companies Act 2006.
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 re­
port. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. 
Independence
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 entities, and we have fulfilled our 
other ethical responsibilities in accordance with these requirements.

Material uncertainty related to going concern
We draw attention to note 2.2 to the financial statements which indicates that the Group is reliant upon further  drawdowns under 
the Senior Debt Facility to construct the Ararguaia Project. These drawdowns  are conditional on the satisfaction of certain conditions 
precedent and there is no guarantee that these conditions will be met. As stated in note 2.2 these events or conditions, along with the 
other matters set out in note 2.2 indicate that a material uncertainty exists that may cast significant doubt on the Group and Parent 
Company’s ability to continue as a going concern. Our opinion is not modified in respect of this matter.
We have determined going concern to be a key audit matter as a result of the judgements and estimates made by the Directors 
and significance of this area.
Our evaluation of the Directors’ assessment of the Group and the Parent Company’s ability to continue to adopt the going concern 
basis of accounting and our response to this key audit matter is set out below:
	
~ We obtained the Directors’ Group cash flow forecast to 31 December 2024. We assessed the reasonableness of underlying 
assumptions, including forecast levels of expenditure used in preparing these forecasts. To assess the reasonableness and 
timings of the cash inflows and outflows, we used our knowledge of the business and  compared the Directors’ forecasts to 
budgets used to raise equity in the 2022 financial year.
	
~ We agreed the total remaining cost associated with bringing the Araguaia Project to the point of generating cashflows and the 
resources available to the company to the most recent cost to complete certificate dated 8 February 2023 that was prepared to 
facilitate the most recent draw down from the senior debt facility. 
	
~ We reviewed the conditions that are required to be complied with to draw down the Senior Debt Facility, discussed these with 
the Directors, and considered factors that could cause non compliance. This included considering the risks associated with 
forecast costs increasing above the available funds, which would prevent further draw downs on the Senior Debt Facility.
	
~ We considered the impact on the Group and Parent Company’s cash flow forecast should the Senior Debt Facility not be 
available due to conditions not being complied with. 
	
~ We assessed the appropriateness of the going concern disclosures included in the financial statements against the 
requirements of the relevant accounting standards.

In auditing the financial statements, we have concluded that the Directors’ use of the going concern basis of accounting in the 
preparation of the financial statements is appropriate. 
Our responsibilities and the responsibilities of the Directors with respect to going concern are described in the relevant sections 
of this report.

Carrying value of exploration and evaluation assets and mine development property is no

in the period for either, the Araguaia mine which is currently  under construction, or the 
Vermelho project, for which a feasibility study has been initiated. 
Valuation of royalty funding arrangement is no longer considered to be a key audit 
matter given the increase in the Group’s materiality reduces the risk of there being a 
material misstatement.
Materiality
Group financial statements as a whole
$7.8million (2021:$4.6 million) based on 1.5% of total assets.

1	
 These are areas which have been subject to a full scope audit by the group engagement team
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.
Our Group audit scope focused on the Group’s significant components, being Araguaia Níquel Metais Ltda, which was subject to a 
full scope audit together with the Parent Company. The Parent Company was audited and the Group audit team and Araguaia Níquel 
Metais Ltda was audited by a BDO network member firm in Brazil.
In addition, Trias Brasil Mineracao Ltda, Horizonte Nickel (IOM) Ltd, Champol (IOM) Ltd, Nickel Production Services BV and Battery 
Material Services BV were the insignificant components, which were subject to specified audit procedures on the significant risk areas 
and analytical procedures performed by the Group audit team.
The remaining components of the Group were considered insignificant and these components were principally subject to analytical 
review procedures which were performed by the Group audit team.
Our involvement with component auditors
For the work performed by component auditors, we determined the level of involvement needed in order to be able to conclude 
whether sufficient appropriate audit evidence has been obtained as a basis for our opinion on the Group financial statements as a 
whole. Our involvement with component auditors included the following:
	
~ Detailed Group reporting instructions were sent to the component auditors, which included the significant areas to be covered 
by the audits (including areas that were considered to be key audit matters), and set out the component materiality and other 
information to be reported to the Group audit team.
	
~ The Group audit team was actively involved in the direction of the audits performed by the component auditor for Group 
reporting purposes, along with the consideration of findings and determination of conclusions drawn.
	
~ The Group audit team reviewed the component auditor’s work papers and engaged with the component auditors during their 
fieldwork and completion phases.
	
~ For the principal operating component in Brazil, the Group audit team also performed audit procedures in respect of the 
significant risk areas.
	
~ The Group audit team has held a number of virtual meetings with the component auditors throughout the engagement. Virtual 
meetings spanned pre-planning, planning, execution and finalisation of the audit engagement. 
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 related to going concern of our report, we have determined the matter below to be 
the key audit matter to be communicated in our report.

Key audit matter 
How the scope of our audit addressed the key audit matter
Valuation of convertible 
loan notes
See notes 4.6 and 22 to the 
financial statements.
In the 2022 financial year, the 
Group issued a convertible 
loan note. The convertible 
loan is a hybrid financial 
instrument with a debt host 
liability component and an 
embedded derivative liability 
component related to the 
conversion option. 
The embedded derivatives 
was valued by independent 
valuation experts using a 
Monte Carlo simulation 
method at both inception 
and at the year end.  This 
method of determining 
fair value is reliant upon 
significant estimations over 
the Company’s future share 
price volatility and GBP:USD 
exchange rate volatility at the 
conversion date.
The host loan is accounted for 
using the amortised cost basis. 
Due to conditions attached to 
when the note holders will be 
repaid, estimation is required 
in determining repayments 
dates and amounts  that 
impact the effective interest 
rate that the host loan is 
unwound over. 
Accordingly, the valuation 
of the convertible loan note 
is  considered to be a key 
audit matter.
Our procedures in relation to the valuation of the convertible loan 
notes debt host and embedded derivatives are set our below.
We assessed the accounting treatment of the convertible loan 
note as a hybrid financial instrument was in accordance with 
accounting standards. We ensured that at inception the fair value 
of the embedded derivative liability was determined first and 
the residual amount was assigned to the debt host liability and 
that associated transaction costs which were deducted, were 
proportionately allocated. 
In respect of the fair value of the embedded derivative at incep­
tion and year end:
	
~ We reviewed the embedded derivative valuation 
methodology adopted to check that the features of the 
embedded derivative had been appropriately modelled.
	
~ We confirmed with BDO valuation experts that 
the modelling was appropriate and in line with our 
understanding of the embedded derivative features. 
	
~ We assessed the reasonableness of the key assumptions 
used in the valuation, including share price and foreign 
exchange rate volatility by reference to independent 
sources of data.
	
~ We assessed the competence and independence of the 
valuation expert used by management. 
In respect of the host loan which is accounted for using the 
amortised cost basis: 
	
~ We tested managements calculation of the effective 
interest rate used to unwind the host loan. This included 
agreeing repayment dates used in the effective interest 
rate calculation were modelled in accordance with the 
terms of the agreement and the timing and quantity of the 
repayments were in agreement with managements most 
recent budgets.
	
~ We also checked the arithmetical accuracy of the 
amortised loan model.
Key observations:
Based on our work, we concur with managements valuation 
methodology and the key estimates used in valuing the host loan 
and embedded derivative.

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:
Group financial statements
Parent company financial statements
2022
2021*
2022*
2021*
Materiality
$7.8 million
$4.6 million 
$5.9 million
$4.1 million
Basis for determining 
materiality
1.5% of total assets
1.5% of total assets
1.5% of total assets
90% of Group 
Materiality
Rationale for the benchmark 
applied
We consider total assets to be the most significant determinant of the 
Group’s financial performance for users of the financial statements, given 
the Group’s mine development focus as a result of the commencement 
of the Araguaia mine construction. There was a significant increase in 
total assets following the commencement of the mine construction 
in May 2022 and additional cash received from the 2021 prospectus 
debt package.
90% of Group 
Materiality
Performance materiality
$5.9million
$ 3.5 million
$4.4 million
$ 3.1 million
Basis for determining 
performance materiality
75% of materiality based on consideration of factors including the level of historical errors and 
nature of activities.

*The presentational currency of the Group and Parent financial statements changed from GBP in 2021 to USD in 2022.
Component materiality
We set materiality for each component of the Group based on a percentage of between 37% and 68% (2021: 4% to 14%) of Group 
materiality dependent on the size and our assessment of the risk of material misstatement of that component.  Component 
materiality ranged from $2,900,000 to $5,300,000 (2021: $196,000 to $623,000). In the audit of each component, we further 
applied performance materiality levels of 75% 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 $0.2million 
(2021:$0.1m).  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 2022 
Report and Accounts 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 Act 2006 reporting
Based on the responsibilities described below and our work performed during the course of the audit, we are required by the 
Companies Act 2006 and ISAs (UK) to report on certain opinions and matters as described below.  
Strategic report and 
Directors’ report 
In our opinion, based on the work undertaken in the course of the audit:
	
~ the information given in the Strategic report and the Directors’ report for the financial year for 
which the financial statements are prepared is consistent with the financial statements; and
	
~ the Strategic report and the Directors’ report have been prepared in accordance with applicable 
legal requirements.
In the light of the knowledge and understanding of the Group and Parent Company and its environment 
obtained in the course of the audit, we have not identified material misstatements in the strategic report 
or the Directors’ report.
Matters on which we 
are required to report by 
exception
We have nothing to report in respect of the following matters in relation to which the Companies Act 
2006 requires us to report to you if, in our opinion:
	
~ adequate accounting records have not been kept by the Parent Company, or returns adequate for 
our audit have not been received from branches not visited by us; or
	
~ the Parent Company financial statements are not in agreement with the accounting records and 
returns; or
	
~ certain disclosures of Directors’ remuneration specified by law are not made; or
	
~ we have not received all the information and explanations we require for our audit.

Responsibilities of Directors
As explained more fully in the Statement of Directors’ Responsibilities, 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 Group’s and the Parent 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 Group or the Parent 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:
	
~ We obtained an understanding of the Company and Group’s activities and considered the laws and regulations of the UK and 
Brazil to be of significance in the context of the Group and component audit. In doing so, we made inquiries of management 
and the Audit Committee, considered the Company and Group’s control environment as it pertains to compliance with laws 
and regulations and considered the activities of the Group. We determined the most significant laws and regulations to be 
Companies Act 2006, elements of the reporting framework, tax legislation and the Brazilian environmental regulations.
	
~ We communicated relevant identified laws and regulations and potential fraud risks to all engagement team members and 
component auditors, and remained alert to any indications of fraud or non-compliance with laws and regulations throughout 
the audit.
	
~ We made inquiries of management and the Board and reviewed Board and Committee minutes to identify any instances of 
irregularities or non-compliance.
	
~ We assessed the suspectibility of the financial statements to material misstatement, including fraud. Our risk 
assessment included: 
•	 Understanding the journals passed throughout the period to ensure that sufficient and appropriate audit procedures are 
designed to gain assurance over journal testing.
•	 Gain an understanding of the tender and procurement process to assess the controls in place.
•	 Review the terms of the financial instruments in place, including the valuation of the convertible loan notes and royalty 
funding arrangements, the contingent consideration,  and the carrying value of exploration and evaluation assets and 
mine development property to gain an understanding of the accounts that are subject to greater management estimate.
Based on our risk assessment, we consider the areas most susceptible to fraud to be the journal testing which derives from the 
valuations of the financial instruments that are subject to managements estimate and the tender and procurement process.
	
~ We agreed the financial statement disclosures to underlying supporting documentation and performed detailed testing on 
accounts balances which were considered to be at a greater risk of susceptibility to fraud.
	
~ In addressing risk of management override of control we performed:	
•	 testing of general ledger journal entries to the financial statements, including verification of journals which we consider 
exhibit higher fraud risk characteristics based on our understanding of the Group. This included testing journals direct to 
cash and expenses, which are outside of the normal purchase to pay cycle. 
•	 procedures over the controls in the tender and procurement process which due to the significant level of additions were 
considered to be at a greater risk of susceptibility to fraud.
•	 procedures on accounts subject to greater management estimate including the valuation of the convertible loan notes 
and royalty funding arrangements, the contingent consideration,  and the carrying value of exploration and evaluation 
assets and mine development property.
We communicated relevant identified laws and regulations and potential fraud risks to all engagement team members and component 
auditors, and remained alert to any indications of fraud or non-compliance with laws and regulations throughout the audit 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. For component engagement teams, we also reviewed the result of their work performed in 
this regard. 
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: 
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 Parent Company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 
2006.  Our audit work has been undertaken so that we might state to the Parent 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 Parent Company and the Parent Company’s members as a body, for our audit work, for this 
report, or for the opinions we have formed.

NOTES TO THE 
FINANCIAL 
STATEMENTS	
1 General information
The principal activity of Horizonte Minerals Plc (‘the Company’) and its subsidiaries (together ‘the Group’) is the exploration and devel­
opment of base metals. The Company’s shares are listed on the AIM market of the London Stock Exchange and on the Toronto Stock 
Exchange. The Company is incorporated and domiciled in England and Wales. The address of its registered office is Rex House, 4-12 
Regent Street, London, SW1Y 4RG.
2 Summary of significant accounting policies
The principal accounting policies applied in the preparation of these Financial Statements are set out below. These policies have been 
consistently applied to all the years presented.
2.1 Basis of preparation
These Financial Statements have been prepared in accordance with UK adopted international accounting standards. Financial State­
ments have been prepared under the historical cost convention except for the following items (refer to individual accounting policies for 
details):
	
~ Contingent consideration
	
~ Financial instruments – fair value through profit and loss
	
~ Cash settled share-based payment liabilities
	
~ Cash flow hedges at fair value through other comprehensive income (OCI)
The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires 
management to exercise its judgement in the process of applying the Group’s Accounting Policies. The areas involving a higher degree of 
judgement or complexity, or areas where assumptions and estimates are significant to the Financial Statements, are disclosed in Note 4. 
As permitted by section 408 of the Companies Act 2006, the statement of comprehensive income of the Parent Company is not present­
ed as part of these Financial Statements.
2.2 Going concern
The Group’s business activities together with the factors likely to affect its future development, performance and position are set out 
in the Chairman’s Statement on pages 6 and 7; in addition, note 3 to the Financial Statements includes the Group’s objectives, policies 
and processes for managing its capital; its financial risk management objectives; details of its financial instruments and its exposure 
to credit and liquidity risk.
The Financial Statements have been prepared on a going concern basis. Although the Group’s assets are not generating revenues and 
an operating loss has been reported, the Directors consider that the Group has sufficient funds to undertake its operating activities 
for a period of at least the next 12 months including any additional expenditure required in relation to its current exploration and de­
velopment projects. The Group has cash reserves and access to liquidity which are considered sufficient by the Directors to fund the 
Group’s committed expenditure both operationally and on its exploration project for the foreseeable future.
The Group concluded a comprehensive funding package of US$633 million in December 2021. The net proceeds of the fundraisings 
will be used towards the construction of the Araguaia project as well as for general working capital purposes. In addition, the compa­
ny has also concluded a US$25million royalty on the Vermelho Project, the net proceeds from the sale of this royalty will be used to 
advance a feasibility study and permitting work streams on the Vermelho project. The equity fundraise (US$197million of the US$633 
million) was finalized and funds received in December 2021 with a further equity fund raise completed in November 2022 for a gross 
US$80 million. The debt elements of the funding package include Convertible Loan Notes (US$65 million), a cost overrun facility 
(US$25 million) and a senior debt facility (US$346.2 million).

HORIZONTE MINERALS 2022 ANNUAL REPORT
HORIZONTE MINERALS 2022 ANNUAL REPORT
Funds from the convertible loan notes and the royalty were received in March 2022. The cost overrun facility funds were received in 
November 2022 and the first drawdown under the senior debt facility was completed in December 2022 following the satisfaction 
of certain conditions precedent customary to a financing of this nature. Subsequent drawdowns under the senior debt facility are 
expected to follow during the remainder of the construction period, again following the satisfaction of certain conditions precedent 
customary to a financing of this nature including but not limited to satisfaction of a cost to complete exercise prior to each draw down 
on the facility, satisfaction of minimum order values from certain suppliers, maintaining the good standing of operational licences and 
permitting, and financial models detailing the Group’s budget forecasting compliance with covenants and ratios. 
The funds held at the year-end along with those to be raised post year end following the satisfaction of any condition’s precedent 
for further drawdowns of the senior debt facility (including access to any of the funds secured as part of the cost overrun facility), 
are considered sufficient by the Directors to execute the construction of the Araguaia Project and fund its general working capital 
requirements for the foreseeable future. However, there exists a risk that the senior debt facility is not able to be drawn due to un­
foreseen circumstances or noncompliance with any conditions precedent which may or may not be within the control of the Group. 
At the time of the second drawdown of the senior debt facility (completed after the year end) the total remaining cost associated with 
bringing the Araguaia Project to the point of generating cashflows were estimated to be  US$356 million which includes a contingency 
of US$19 million. This will be funded through the undrawn senior debt facility of US$341.2 million. In addition, the Group has a cost 
overrun facility available of US$25million. If expected or actual costs were to increase as a result of delays or increases in capital or 
pre-production operating costs by more than US$48 million (14% increase) of the total budget the project would fail the cost to com­
plete test, a condition precedent of the senior debt facility. Additionally, despite being approximately 45% complete a number of risks 
still exist around escalation costs linked to several of the major construction packages (these include labour and materials) potentially 
exceeding the contingency. This could result in future drawdowns on the senior debt facility not being permitted and require the Group 
to pursue alternative sources of funding to meet its commitments. 
As the project moves into operational ramp-up phase there are a number of risk areas around commissioning the furnace and rotary 
kiln. If any of these ramp-up risks exceed the pre-production funding allocated to the unit areas there will be a requirement for addi­
tional funding.
As some of these events are outside of the Group’s control, a material uncertainty exists which may cast significant doubt about the 
Group’s continued ability to operate as a going concern and its ability 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 were unable to continue as a going concern.
2.3 Changes in accounting policy and disclosures

b) New and amended standards, and interpretations issued but not yet effective for the financial year beginning 1 January 2022 and 
not early adopted
At the date of authorisation of these Consolidated Financial Statements, the following new standards, amendments and interpretations 
to existing standards have been published but are not yet effective and have not been adopted early by the Group.
Standard 
Detail 
Effective date 
IAS 1 
Amendment – regarding the classification of liabilities 
1 January 2024
IAS 8

Management anticipates that all the pronouncements will be adopted in the Group’s accounting policies for the first period beginning 
after the effective date of the pronouncement. The adoption of the new and amended standards are not expected to have a material 
impact on the Group's consolidated financial statements, except for the IAS1 amendment regarding the classification of liabilities. The 
amendment will impact the classification of the convertible loan notes from non-current to current as the conversion option can be 
exercised at any time.
2.4 Basis of consolidation and business acquisitions
Horizonte Minerals Plc was incorporated on 16 January 2006. On 23 March 2006 Horizonte Minerals Plc acquired the entire issued share 
capital of Horizonte Exploration Limited (HEL) by way of a share for share exchange. The transaction was treated as a group reconstruction 
and was accounted for using the merger accounting method as the entities were under common control before and after the acquisition.

Subsidiaries are entities controlled by the Group. Control is achieved when the Group is exposed, or has rights, to variable returns from 
its involvement with the investee and has the ability to affect those returns through its power over the investee. 
The Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including:
	
~ The contractual arrangement with the other vote holders of the investee.
	
~ Rights arising from other contractual arrangements.
	
~ The Group’s voting rights and potential voting rights.
Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control of the 
subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidat­
ed financial statements from the date the Group gains control until the date the Group ceases to control the subsidiary.
Other than for the acquisition of HEL as noted above, the Group uses the acquisition method of accounting to account for business 
combinations. The consideration transferred for the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities in­
curred and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting 
from a contingent consideration arrangement. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business 
combination are measured initially at their fair values at the acquisition date. Acquisition-related costs are expensed as incurred unless 
they result from the issuance of shares, in which case they are offset against the premium on those shares within equity.
If an acquisition is achieved in stages, the acquisition date carrying value of the acquirer’s previously held equity interest in the acquiree 
is remeasured to fair value at the acquisition date through profit or loss.
Any contingent consideration to be transferred by the Group is recognised at fair value at the acquisition date. Subsequent changes to 
the fair value of the contingent consideration that is deemed to be an asset or a liability is recognised in accordance with IFRS9 either 
in profit or loss or as a change in other comprehensive income. The unwinding of the discount on contingent consideration liabilities is 
recognised as a finance charge within profit or loss. Contingent consideration that is classified as equity is not remeasured, and its sub­
sequent settlement is accounted for within equity.
The excess of the consideration transferred and the acquisition date fair value of any previous equity interest in the acquiree over the 
fair value of the Group’s share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net 
assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognised directly in profit or loss.
Inter-company transactions, balances and unrealised gains on transactions between Group companies are eliminated. Accounting poli­
cies of subsidiaries have been changed where necessary to ensure consistency with policies adopted by the Group.
Investments in subsidiaries are accounted for at cost less impairment.

2.4 (b) Subsidiaries and Acquisitions
The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Company (its 
subsidiaries) made up to 31 December each year. Control is recognised where an investor is expected, or has rights, to variable returns 
from its investment with the investee, and has the ability to affect these returns through its power over the investee. Based on the 
circumstances of the acquisition an assessment will be made as to whether the acquisition represents an acquisition of an asset or the 
acquisition of asset. In the event of a business acquisition, the assets, liabilities and contingent liabilities of a subsidiary are measured 
at their fair value at the date of acquisition.  Any excess of the cost of the acquisition over the fair values of the identifiable net assets 
acquired is recognised as a “fair value” adjustment.  
If the cost of the acquisition is less than the fair value of net assets of the subsidiary acquired, the difference is recognised directly in 
profit or loss. In the event of an asset acquisition assets and liabilities are assigned a carrying amount based on relative fair value.
The results of subsidiaries acquired or disposed of during the year are included in the statement of comprehensive income from the 
effective date of acquisition or up to the effective date of disposal, as appropriate.
Where necessary, adjustments are made to the financial statements of subsidiaries to bring the accounting policies into line with those 
used by the Group.
2.5 Intangible Assets
(a) Goodwill
Goodwill represents the excess of the cost of an acquisition over the fair value of the Group’s share of the net identifiable assets, lia­
bilities and contingent liabilities of the acquired subsidiary at the date of acquisition. Goodwill arising on the acquisition of subsidiaries 
is included in ‘intangible assets’. Goodwill is tested annually for impairment and carried at cost less accumulated impairment losses. 
Impairment losses on goodwill are not reversed. Gains and losses on the disposal of an entity include the carrying amount of goodwill 
relating to the entity sold.
Goodwill is allocated to cash generating units for the purpose of impairment testing. The allocation is made to those cash-generating 
units or groups of cash-generating units that are expected to benefit from the business combination in which the goodwill arose, iden­
tified according to operating segment.
(b) Exploration and evaluation assets
The Group capitalises expenditure in relation to exploration and evaluation of mineral assets when the legal rights are obtained and are 
initially valued and subsequently carried at cost less any subsequent impairment. Expenditure included in the initial measurement of 
exploration and evaluation assets and which are classified as intangible assets relate to the acquisition of rights to explore, topograph­
ical, geological, geochemical and geophysical studies, exploratory drilling, trenching, sampling and activities to evaluate the technical 
feasibility and commercial viability of extracting a mineral resource. 
Exploration and evaluation assets arising on business combinations are included at their acquisition-date fair value in accordance with 
IFRS 3 (revised) ‘Business combinations’. Other exploration and evaluation assets and all subsequent expenditure on assets acquired as 
part of a business combination are recorded and held at cost.
Exploration and evaluation assets are assessed for impairment when facts and circumstances suggest that the carrying amount of an 
asset may exceed its recoverable amount. The assessment is carried out on a project by project basis as each project is considered as a 
cash generating unit. 
Impairment reviews for deferred exploration and evaluation expenditure are carried out on a project by project basis, with each 
project representing a potential single cash generating unit. In accordance with the requirements of IFRS 6, an impairment review is 
undertaken when indicators of impairment arise such as: 
i.	
unexpected geological occurrences that render the resource uneconomic;
ii.	
title to the asset is compromised;
iii.	 variations in mineral prices that render the project uneconomic;
iv.	 substantive expenditure on further exploration and evaluation of mineral resources is neither budgeted nor planned; and
v.	
the period for which the Group has the right to explore has expired and is not expected to be renewed.
See note 2.7 for impairment review process if impairment indicators are identified.
Whenever the exploration for and evaluation of mineral resources does not lead to the discovery of commercially viable quantities of 
mineral resources or the Group has decided to discontinue such activities of that unit, the associated expenditures are written off to 
profit or loss. Whenever a commercial discovery is the direct result of the exploration and evaluation assets, upon the decision to pro­
ceed with development of the asset and initial funding arrangements are in place the costs shall be transferred to a Mine Development 
asset within property, plant and equipment.    
(c)  Acquisitions of Mineral Exploration Licences
Acquisitions of Mineral Exploration Licences through acquisition of non-operational corporate structures that do not represent a busi­
ness, and therefore do not meet the definition of a business combination, are accounted for as the acquisition of an asset and recog­
nised at the fair value of the consideration. Related future consideration if contingent is recognised when the probability that it will 
be paid changes.
2.6 Property, plant and equipment
Mine development property
Following determination of the technical feasibility and commercial viability of a mineral resource, the relevant expenditure is trans­
ferred from exploration and evaluation assets to mine development property. 
Further development costs are capitalised to mine development properties, if and only if, it is probable that future economic benefits 
associated with the item will flow to the entity and the cost can be measured reliably. Cost is defined as the purchase price and directly 
attributable costs. Once the asset is considered to be capable of operating in a manner intended by management, commercial produc­
tion is declared, and the relevant costs are depreciated. Evaluated mineral property is carried at cost less accumulated depreciation and 
accumulated impairment losses.
Short lived Property, plant and equipment
All other property, plant and equipment is stated at historic cost less accumulated depreciation. Historic cost includes expenditure that 
is directly attributable to the acquisition of the items.
Subsequent costs are included in the asset’s carrying amount or recognised as a separate asset, as appropriate, only when it is probable 
that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. Major 
repairs and maintenance are capitalised, all other repairs and maintenance costs are charged to profit or loss during the financial period 
in which they are incurred.

HORIZONTE MINERALS 2022 ANNUAL REPORT
Depreciation and amortisation
Mine development property is not depreciated prior to commercial production but is reviewed for impairment annually (see “Impairment 
of non-financial assets” section below). Upon commencement of commercial production, mine development property is transferred to 
a mining property and is depreciated on a units-of-production basis. Only proven and probable reserves are used in the tonnes mined 
units of production depreciation calculation.
Depreciation is charged on a straight-line basis  for all other property, plant and equipment, so as to write off the cost of assets, over their 
estimated useful lives, using the straight-line method, on the following bases:
Office equipment
  25%
Vehicles and other field equipment
  25% – 33%
Land is not depreciated. The asset’s residual values and useful lives are reviewed, and adjusted if appropriate, at the end of each report­
ing period.  
An asset’s carrying amount is written down immediately to its recoverable amount if the assets carrying amount is greater than its 
estimated recoverable amount.
Capitalisation of borrowing costs
Borrowing costs are expensed except where they relate to the financing of construction or development of qualifying assets. Borrowing 
costs directly related to financing of qualifying assets in the course of construction are capitalised to the carrying value of the Araguaia 
mine development property. Where funds have been borrowed specifically to the finance the Project, the amount capitalised represents 
the actual borrowing costs incurred net of all interest income earned on the temporary re-investment of these borrowings prior to utili­
sation. Borrowing costs capitalised include:
	
~ Interest charge on the royalty finance
	
~ Adjustments to the carrying value of the royalty finance
	
~ Unwinding of discount and adjustment to carrying value on contingent consideration payable for Araguaia
	
~ Interest charge on the convertible loan note liability
	
~ Interest charge on the senior debt facility
	
~ Interest charge on the cost overrun facility
The capitalisation of adjustments to the carrying values as a result of changes in estimates is an accounting policy choice under IFRS 
and management have selected to capitalise. To the extent that the Group borrows funds generally and uses them for the purpose of 
obtaining a qualifying asset, the Group determines the amount of borrowing costs eligible for capitalisation by applying a capitalisation 
rate to the expenditures on that asset. The capitalisation rate is the weighted average of the borrowing costs applicable to all borrowings 
of the entity that are outstanding during the period.
All other borrowing costs are recognized as part of interest expense in the year which they are incurred.
2.7 Impairment of non-financial assets
Assets that have an indefinite useful life, such as goodwill are not subject to amortisation and are tested annually for impairment. 
At each balance sheet date, the Group reviews the carrying amounts of its property, plant and equipment and intangible assets to 
determine whether there is any indication that those assets have suffered impairment. Prior to carrying out impairment reviews, the 
significant cash generating units are assessed to determine whether they should be reviewed under the requirements of IFRS 6 – Ex­
ploration for and Evaluation of Mineral Resources or IAS 36 – Impairment of Assets. Such determination is by reference to the stage of 
development of the project and the level of reliability and surety of information used in calculating value in use or fair value less costs to 
sell. Impairment reviews performed under IFRS 6 are carried out on a project by project basis, with each project representing a potential 
single cash generating unit. An impairment review is undertaken when indicators of impairment arise; typically when one of the follow­
ing circumstances applies:
i.	
sufficient data exists that render the resource uneconomic and unlikely to be developed
ii.	
title to the asset is compromised
iii.	 budgeted or planned expenditure is not expected in the foreseeable future
iv.	 insufficient discovery of commercially viable resources leading to the discontinuation of activities
Impairment reviews performed under IAS 36 are carried out when there is an indication that the carrying value may be impaired. Such 
key indicators (though not exhaustive) to the industry include:
i.	
a significant deterioration in the spot price of nickel
ii.	
a significant increase in production costs
iii.	 a significant revision to, and reduction in, the life of mine plan
If any indication of impairment exists, the recoverable amount of the asset is estimated, being the higher of fair value less costs to sell 
and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount 
rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of 
future cash flows have not been adjusted.
If the recoverable amount of an asset (or cash generating unit) is estimated to be less than its carrying amount, the carrying amount of the 
asset (or cash generating unit) is reduced to its recoverable amount. Such impairment losses are recognised in profit or loss for the year.
Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash generating unit) is increased to the revised 
estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have 
been determined had no impairment loss been recognised for the asset (or cash generating unit) in prior years. A reversal of an impair­
ment loss is recognised in profit or loss for the year.
2.8 Foreign currency translation
(a) Functional and presentation currency
Items included in the Financial Statements of the Group’s entities are measured using the currency of the primary economic environment 
in which the entity operates (the ‘functional currency’). The functional currency of the UK and Isle of Man entities is Pounds Sterling and 
the functional currency of the Brazilian entities is Brazilian Real. The functional currency of the project financing subsidiaries incorporat­
ed in the Netherlands is USD, however debt costs capitalised to the mine development asset are recorded in Brazilian Real. 
Horizonte Minerals Plc changed its presentation currency from Pounds Sterling to US Dollars effective 1 January 2022. 
The presentation currency has been revised as the financing package concluded by the Group to construct the Araguaia project 
is denominated in US Dollars and future revenues will also be in US Dollars. The board therefore believes that US Dollar financial 
reporting provides more relevant presentation of the group’s financial position, funding and treasury functions, financial perfor­
mance and its cash flows.
A change in presentation currency represents a change in an accounting policy in terms of IAS 8 Accounting Policies, Changes in Ac­
counting Estimates and Errors requiring the restatement of comparative information. In accordance with IAS 21 The Effects of Changes 
in Foreign Exchange Rates, the following methodology was followed in restating historical financial information from Pounds Sterling 
to US Dollar:
	
~ Assets and liabilities were translated at the relevant closing exchange rate at the end of the reporting period. Items of income and 
expenditure and cash flows were translated at average rates of exchange for the period;
	
~ The foreign currency translation reserve was reset to nil as at 1 January 2006, the date on which the group adopted IFRS. Share 
capital and premium and other reserves, as appropriate, were translated at the historic rates prevailing at the dates of underlying 
transactions; and
	
~ The effects of translating the group’s financial results and financial position into US Dollar were recognised in the foreign currency 
translation reserve.
The exchange rates used were as follows:
GBP/USD
31 December 2021
31 December 2020
Closing rate
1.3477
1.3649
Average rate
1.3757
1.2837
USD/BRL
Closing rate
5.5710
5.1967
Average rate
5.3810
5.0869
(b) Transactions and balances
Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the trans­
actions or valuation where such items are re-measured. Foreign exchange gains and losses resulting from the settlement of such trans­
actions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are 
recognised in profit or loss.
(c) Group companies
The results and financial position of all the Group’s entities (none of which has the currency of a hyperinflationary economy) that have a 
functional currency different from the presentation currency are translated into the presentation currency as follows:
1.	assets and liabilities for each statement of financial position presented are translated at the closing rate at the date of that state­
ment of financial position;
2.	each component of profit or loss is translated at average exchange rates during the accounting period (unless this average is not 
a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and 
expenses are translated at the dates of the transactions); and
3.	all resulting exchange differences are recognised in other comprehensive income. 
On consolidation, exchange differences arising from the translation of the net investment in foreign entities, and of monetary items 
receivable from foreign subsidiaries for which settlement is neither planned nor likely to occur in the foreseeable future are taken to 
other comprehensive income. When a foreign operation is sold, such exchange differences are recognised in profit or loss as part of the 
gain or loss on sale.
Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity 
and retranslated at the end of each reporting period.

The major exchange rates used for the revaluation of the statement of financial position at 31 December 2022 were Pounds Sterling 
£1:US$1.2039 (31 December 2022: £1:US$1.3477), Brazilian Real (R$):US$0.192 (31 December 2021: R$:US$0.180).
Foreign currency translation reserve includes movements that relate to the retranslation of the subsidiaries whose functional currencies 
are not United States Dollar.
During the year ended 31 December 2022, the Brazilian Real strengthened by 7% since 31 December 2021. Currency translation dif­
ferences for the year of US$6.7 million loss (2021:US$258,976 gain) included in the consolidated statement of comprehensive income 
arose on the translation of property plant and equipment, intangible assets and cash and cash equivalents denominated in Brazilian Real.
The foreign exchange gain for the year of US$8.5 million included in the statement of comprehensive income relates to the translation 
differences of foreign currency cash and cash equivalents balances, liability financing arrangements and intercompany balances denom­
inated in currencies other than the functional currency of the entity. 
2.9 Financial instruments
Financial instruments are measured as set out below.  Financial instruments carried on the statement of financial position include 
cash and cash equivalents, trade and other receivables, trade and other payables and loans to group companies.
Financial instruments are initially recognised at fair value when the group becomes a party to their contractual arrangements. Trans­
action costs directly attributable to the instrument’s acquisition or issue are included in the initial measurement of financial assets 
and financial liabilities, except for financial instruments classified as at fair value through profit or loss (FVTPL). The subsequent 
measurement of financial instruments is dealt with below.
Financial assets
The Group classifies its financial assets into one of the categories discussed below, depending on the purpose for which the asset was 
acquired. Other than financial assets in a qualifying hedging relationship, the Group’s accounting policy for each category is as follows:
Fair value through profit or loss
This category comprises in-the-money derivatives. They are carried in the statement of financial position at fair value with changes in 
fair value recognised in the statement of comprehensive income in the operating profit or loss line. All directly attributable transaction 
costs are recognised in profit or loss as incurred. 
The buy-back options in the Group’s royalty financing arrangements are embedded derivative financial assets measured at fair value 
through profit or loss.
Amortised cost 
Financial assets that arise principally from assets where the objective is to hold these assets in order to collect contractual cash flows 
and the contractual cash flows are solely payments of principal and interest. They are initially recognised at fair value plus transaction 
costs that are directly attributable to their acquisition or issue, and are subsequently carried at amortised cost using the effective inter­
est rate method, less provision for impairment.
Any gain or loss arising on derecognition is recognised directly in profit or loss and presented in other gains or losses, together with for­
eign exchange gains or losses. Impairment losses are presented as separate line item in the statement of profit or loss. A gain or loss on 
a debt investment that is subsequently measured at FVTPL is recognised in profit or loss and presented net within other gains or losses 
in the period in which it arises. On derecognition of a financial asset, the difference between the proceeds received or receivable and the 
carrying amount of the asset is included in profit or loss.
Financial assets at amortised cost consist of trade receivables and other receivables (excluding taxes), cash and cash equivalents, and 
related party intercompany loans 
Impairment provisions for receivables and loans to related parties and subsidiaries are recognised based on a forward looking expected 
credit loss model. The methodology used to determine the amount of the provision is based on whether there has been a significant 
increase in credit risk since initial recognition of the financial asset. For those where the credit risk has not increased significantly since 
initial recognition of the financial asset, twelve month expected credit losses along with gross interest income are recognised. For those 
for which credit risk has increased significantly, lifetime expected credit losses along with the gross interest income are recognised. For 
those that are determined to be credit impaired, lifetime expected credit losses along with interest income on a net basis are recognised.
Cash and cash equivalents
Cash and cash equivalents are carried in the statement of financial position at cost. For the purpose of the cash flow statement, cash and 
cash equivalents comprise cash on hand, deposits held at call with banks, other short term highly liquid investments with a maturity of 
three months or less at the date of purchase.
Fair value through other comprehensive income
The Group does not have any assets held at fair value through other comprehensive income.
Financial liabilities
The Group classifies its financial liabilities into one of two categories, depending on the purpose for which the liability was acquired.
Fair value through profit or loss
This category comprises out-of-the-money derivatives where the time value does not offset the negative intrinsic value. They are car­
ried in the consolidated statement of financial position at fair value with changes in fair value recognised in the consolidated statement 
of comprehensive income. All directly attributable transaction costs are recognised in profit or loss as incurred. The Group’s embedded 
derivative in its convertible loan notes is measured at fair value through profit or loss.
Other financial liabilities
Financial liabilities are subsequently measured at amortised cost using the effective interest method, except for financial liabilities des­
ignated at fair value through profit or loss, that are carried subsequently at fair value with gains and losses recognised in the profit and 
loss statement. 
The effective interest method is a method of calculating the amortised cost of a financial liability and of allocating interest expense over 
the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected 
life of the financial liability, or, where appropriate, a shorter period. 
The Group’s financial liabilities initially measured at fair value and subsequently recognised at amortised cost include accounts payables 
and accrued liabilities, Group’s Royalty liability, Convertible loan notes liability, Senior debt facility as well as the cost overrun facility.  
Hedge accounting
The Group has elected to adopt the hedge accounting requirements of IFRS 9 Financial Instruments, in respect of its foreign exchange 
hedging strategy. The Group enters into hedge relationships where the critical terms of the hedging instrument and the hedged item 
match, therefore, for the prospective assessment of effectiveness a qualitative assessment is performed. Hedge effectiveness is deter­
mined at the origination of the hedging relationship. Quantitative effectiveness tests are performed at each period end to determine the 
continuing effectiveness of the relationship. In instances where changes occur to the hedged item which result in the critical terms no 
longer matching, the hypothetical derivative method is used to assess effectiveness.
Foreign exchange risk arises when the Group enters into transactions denominated in a currency other than their functional currency. 
Where the risk to the Group is considered to be significant, the Group will enter into a matching non-deliverable forward foreign ex­
change contracts with a reputable bank. 
The hedged forecast transactions denominated in foreign currency are expected to occur between 14 May 2022 and 31 March 2025. 
Gains and losses recognised in the hedging reserve in equity on non-deliverable forward foreign exchange contracts are recognised in 
the consolidated statement of comprehensive income in the period during which the hedged forecast transaction affects the consolidat­
ed statement of comprehensive income,   unless the gain or loss is included in the initial carrying value of non-current assets through a 
basis adjustment (immediate transfer from cash flow hedging reserve to cost of asset) in which case recognition is over the lifetime of 
the asset as it is depreciated. The ineffective portion of the cash flow hedge is recognised immediately in the profit or loss.
2.10 Taxation

The tax credit or expense for the period comprises current and deferred tax. Tax is recognised in the Income Statement, except to the 
extent that it relates to items recognised in other comprehensive income or directly in equity. In this case, the tax is also recognised in 
other comprehensive income or directly in equity, respectively.
The charge for current tax is calculated on the basis of the tax laws enacted or substantively enacted by the end of the reporting period 
in the countries where the company and its subsidiaries operate and generate taxable income. Management periodically evaluates 
positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes 
provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.
Deferred tax is accounted for using the liability method in respect of temporary differences arising from differences between the carrying 
amount of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit. 
However, deferred tax liabilities are not recognised if they arise from the initial recognition of goodwill; deferred tax is not accounted 
for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the 
transaction affects neither accounting nor taxable profit or loss.
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. Deferred 
tax assets are recognised on tax losses carried forward to the extent that the realisation of the related tax benefit through future 
taxable profits is probable.

HORIZONTE MINERALS 2022 ANNUAL REPORT
HORIZONTE MINERALS 2022 ANNUAL REPORT
Deferred tax liabilities are recognised for taxable temporary differences arising on investments in subsidiaries and associates, and inter­
ests in joint ventures, except where the Company is able to control the reversal of the temporary difference and it is probable that the 
temporary difference will not reverse in the foreseeable future.
Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax lia­
bilities and when the deferred tax assets and liabilities relate to taxes levied by the same taxation authority on either the same taxable 
entity or different taxable entities where there is an intention to settle the balances on a net basis.
Deferred tax is calculated at the tax rates (and laws) that have been enacted or substantively enacted by the Statement of Financial 
Position date and are expected to apply to the period when the asset is realised or the liability is settled.
Deferred tax assets and liabilities are not discounted.
2.11 Share capital
Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new ordinary shares or options are shown 
in equity as a deduction, net of tax, from the proceeds.
2.12 Trade payables
Trade payables are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppli­
ers. Accounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as 
non-current liabilities.
Trade payables are initially recognised at fair value and subsequently measured at amortised cost using the effective interest method.
2.13 Leases
All leases are accounted for by recognising a right-of-use assets due to a lease liability except for:
	
~ Lease of low value assets; and
	
~ Leases with duration of 12 months or less
The Group has such short duration leases and lease payments are charged to the income statement with the exception of Araguaia’s 
(Group’s wholly owned subsidiary) leases for the Belo Horizonte office and vehicles lease.
Lease liabilities are measured at the present value of the contractual payments due to the lessor over the lease term, with the discount 
rate determined by reference to the rate inherent in the lease unless (as is typically the case) this is not readily determinable, in which 
case the group’s incremental borrowing rate on commencement of the lease is used. Variable lease payments are only included in the 
measurement of the lease liability if they depend on an index or rate. In such cases, the initial measurement of the lease liability assumes 
the variable element will remain unchanged throughout the lease term. Other variable lease payments are expensed in the period to 
which they relate.
On initial recognition, the carrying value of the lease liability also includes:
	
~ amounts expected to be payable under any residual value guarantee;
	
~ the exercise price of any purchase option granted in favour of the group if it is reasonable certain to assess that option;
	
~ any penalties payable for terminating the lease, if the term of the lease has been estimated on the basis of termination option 
being exercised.
Right of use assets are initially measured at the amount of the lease liability, reduced for any lease incentives received, and increased for:
	
~ lease payments made at or before commencement of the lease;
	
~ initial direct costs incurred; and
	
~ the amount of any provision recognised where the group is contractually required to dismantle, remove or restore the leased asset 
Subsequent to initial measurement lease liabilities increase as a result of interest charged at a constant rate on the balance outstanding 
and are reduced for lease payments made. Right-of-use assets are amortised on a straight-line basis over the remaining term of the 
lease or over the remaining economic life of the asset if, rarely, this is judged to be shorter than the lease term.
2.14 Share-based payments and incentives
The Group operates equity-settled, share-based compensation plans, under which the entity receives services from employees as con­
sideration for equity instruments (options) of the Group. The fair value of employee services received in exchange for the grant of share 
options are recognised as an expense. The total expense to be apportioned over the vesting period is determined by reference to the fair 
value of the options granted:
	
~ including any market performance conditions; 
	
~ excluding the impact of any service and non-market performance vesting conditions; and 
	
~ including the impact of any non-vesting conditions.
Non-market performance and service conditions are included in assumptions about the number of options that are expected to vest. 
The total expense is recognised over the vesting period, which is the period over which all of the specified vesting conditions are to be 
satisfied. At the end of each reporting period the Group revises its estimate of the number of options that are expected to vest.
It recognises the impact of the revision of original estimates, if any, in profit or loss, with a corresponding adjustment to equity.
When options are exercised, the Company issues new shares. The proceeds received net of any directly attributable transaction costs 
are credited to share capital (nominal value) and share premium.
The fair value of goods or services received in exchange for shares is recognised as an expense.
2.15 Segment reporting
Operating segments are reported in a manner consistent with the internal reporting provided to the Chief Executive Officer, the Compa­
ny’s chief operating decision-maker (“CODM”).
2.16 Finance income
Interest income is recognised using the effective interest method, taking into account the principal amounts outstanding and the interest 
rates applicable.
2.17 Provisions and Contingent Liabilities
Provisions are recognised when the Group has a present legal or constructive obligation as a result of past events; it is probable that an 
outflow of resources will be required to settle the obligation; and the amount can be reliably estimated.
Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate 
that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision 
due to passage of time is recognised as finance cost.
Contingent liabilities are potential obligations that arise from past events and whose existence will only be confirmed by the occurrence 
of one or more uncertain future events that, however, are beyond the control of the Group. Furthermore, present obligations may consti­
tute contingent liabilities if it is not probable that an outflow of resources will be required to settle the obligation, or a sufficiently reliable 
estimate of the amount of the obligation cannot be made.
The company has contingent consideration arising in respect of mineral asset acquisitions. Details are disclosed in note 4.2. 
Restoration, Rehabilitation and Environmental Provisions 
Management uses its judgement and experience to provide for and amortise the estimated mine closure and site rehabilitation over the 
life of the mine. Provisions are discounted at a discounted at a pre-tax rate reflecting current market assessments of the time value of 
money and risks specific to the liability and cost base inflated at an appropriate rate. The ultimate closure and site rehabilitation costs are 
uncertain and cost estimates can vary in response to many factors including changes to relevant legal requirements or the emergence of 
new restoration techniques. The expected timing and extent of expenditure can also change, for example in response to changes in ore 
reserves or processing levels. As a result, there could be significant adjustments to the provisions established which could affect future 
financial results.

3.1 Financial risk factors
The main financial risks to which the Group’s activities are exposed are liquidity and fluctuations on foreign currency. The Group’s overall 
risk management programme focusses on the unpredictability of financial markets and seeks to minimise potential adverse effects on 
the Group’s financial performance. 
Risk management is carried out by the Board of Directors under policies approved at the quarterly Board meetings. The Board frequently 
discusses principles for overall risk management including policies for specific areas such as foreign exchange. 
(a) Liquidity risks
In keeping with similar sized mineral exploration groups, the Group’s continued future operations depend on the ability to raise suffi­
cient working capital through the issue of equity share capital or various forms of debt funding. Liquidity risk arises from the Group’s 
management of working capital and the finance charges and principal repayments on its debt instruments. At present the settlement of 
some of the Group’s liabilities are contingent upon reaching production. There is however a risk that the Group will encounter difficulty 
in meeting its financial obligations as they fall due. The Group’s policy is to ensure that it will always have sufficient cash to allow it to 
meet its liabilities when they become due. To achieve this aim, it seeks to maintain cash balances (or agreed facilities) to meet expected 
requirements for a period of at least 6 months. All cash, with the exception of that required for immediate working capital requirements, 
is held on short-term deposit. 
The Board receives rolling 12-month cash flow projections on a monthly basis as well as information regarding cash balances and (as 
noted above) the value of the Group’s deposits. At the end of the financial year, these projections indicated that the Group expect­
ed to have sufficient liquid resources to meet its obligations under all reasonably expected circumstances. The liquidity risk of each 
group entity is managed centrally by the group treasury function. Each operation has a facility with group treasury, the amount of the 
facility being based on budgets. The budgets are set locally and agreed by the board in advance, enabling the Group’s cash require­
ments to be anticipated.

(b) Foreign currency risks
The Group operates internationally and is exposed to foreign exchange risk arising from various currency exposures, primarily with re­
spect to the Brazilian Real, US Dollar and the Pound Sterling. 
Foreign exchange risk arises from future commercial transactions, recognised assets and liabilities and net investments in foreign 
operations that are denominated in a foreign currency. The Group holds a proportion of its cash in US Dollars and Brazilian Reals to 
hedge its exposure to foreign currency fluctuations and recognises the profits and losses resulting from currency fluctuations as and 
when they arise. 
The Group is predominantly exposed to currency risk on its BRL denominated capital expenditure for the development of the Araguaia 
Ferronickel Project. With the funding base being primarily US Dollars, the Group and its senior lenders agreed to implement a foreign 
exchange hedging strategy that ensures that at least 70% of its BRL denominated capital expenditure is hedged by entering into a series 
of non-deliverable forward transactions.
At 31 December 2022, if the Brazilian Real had weakened/strengthened by 5% against US Dollar with all other variables held constant, 
post tax loss for the year would have been approximately US$16 million (2021: US$3million) lower/higher mainly as a result of foreign 
exchange losses/gains on translation of Brazilian Real assets, liabilities and expenditure. If the USD:GBP rate had increased by 5% the 
effect would be US$16 million (2021: US$13 million). 
As of 31 December 2022 the Group’s net exposure to foreign exchange risk was as follows:

(c) Interest rate risk
The Group is exposed to interest rate risk on the variable rate on the senior debt facility. As at 31 December 2022 more than 80% of 
the Group’s external borrowings are fixed rate borrowings. The Group’s borrowings at variable rate were denominated in US Dollar. The 
Group’s interest rate risk also arises from its cash held on short-term deposit for which the Directors use a mixture of fixed and variable 
rate deposits. The Group currently does not hedge it exposure interest rate fluctuations. The cost of managing the interest rate fluctua­
tions exceeds any potential benefits. The Directors monitor this risk on an ongoing basis and will review this as the Group moves towards 
production. Fluctuations in interest rates are not expected to have a significant impact on profit or loss or equity.

(d) Commodity price risk
The Group is exposed to the price fluctuation of its products from the Araguaia and Vermelho projects, being FerroNickel and Nickel 
Cobalt respectively. The Group has royalties over both its project which is denominated as a fixed percentage of the product over a 
certain number of tonnes produced. Given the Group is current in the development phase and is not yet producing any revenue, the 
costs of managing exposure to commodity price risk exceed any potential benefits. The Directors monitor this risk on an ongoing basis 
and will review this as the group moves towards production. The Group’s exposure to commodity prices amounted to the carrying 
value of the Araguaia royalty liability of US$48,783,266 (2021: US$44,496,504) and the Vermelho royalty liability of US$40,961,987 
(2021: US$0). A 15% adjustment to the long-term commodity prices would result in a royalty liability valuation variance of between 
US$6.1million and US$7.5million. In addition the commodity price exposure also impacts the royalty buy-back options valuation, re­
sulting in an adjustment to fair value of US$5,007,496 (2021: US$4,950,000) and US$9,481,891 on the  Araguaia and Vermelho 
derivative assets respectively. A 15% adjustment to the long-term commodity prices would results in valuation variance of between 
US$2.7million and US$3.7million.
(e) Credit risk
Credit risk arises from cash and cash equivalents and outstanding receivables including intercompany loan receivable balances. The 
Group maintains cash and short-term deposits with a variety of credit worthy financial institutions and considers the credit ratings of 
these institutions before investing in order to mitigate against the associated credit risk. 
The Group’s exposure to credit risk amounted to US$154,027,967 (2022: US$210,492,280) and represents the Group cash positions. 
The Company’s exposure to credit risk amounted to US$393,587,841 (2021: US$292,681,304). Of this amount US$368,980,168 (2021: 
US$94,085,540) is due from subsidiary companies and US$24,607,673 represents cash holdings (2021: US$198,595,764). See note 34 
for adjustments for provisions for expected credit losses for the intercompany receivables from subsidiary companies.
3.2 Capital risk management
The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern, in order to provide 
returns for shareholders and to enable the Group to continue its exploration and evaluation activities. The Group monitors its level of 
cash resources available against future planned exploration and evaluation activities and may issue new shares in order to raise further 
funds from time to time. 
As indicated above, the Group holds cash reserves on deposit at several banks and in different currencies until they are required and in 
order to match where possible with the corresponding liabilities in that currency.
3.3 Fair value estimation
Financial instruments not measured at fair value
Financial instruments not measured at fair value includes cash and cash equivalents, trade and other receivables, trade and other paya­
bles, contingent and deferred consideration, royalty financing arrangements, convertible loan notes and loans and borrowings.
Due to their short-term nature, the carrying value of cash and cash equivalents, trade and other receivables, and trade and other paya­
bles approximates their fair value.

In 2019 the Group entered into a royalty funding arrangement with Orion Mine Finance securing a gross upfront payment of $25,000,000 
before fees in exchange for a royalty over the first 426k tonnes of nickel produced from the Araguaia Ferronickel project. The agreement 
includes several prepayment options embedded within the agreement enabling the Group to reduce the royalty rate, these options are 
carried at fair value.  In 2022 the Group entered into a second royalty funding arrangement with Orion Mine Finance securing a gross 
upfront payment of $25,000,000 before fees in exchange for a royalty over the tonnes of nickel cobalt produced over the life of mine 
from the Vermelho Nickel Cobalt project. The agreement also includes several prepayment options embedded within the agreement 
enabling the Group to reduce the royalty rate, these options are carried at fair value. Details of the agreements are included in note 21.  
The future expected nickel and cobalt prices and volatility of the nickel and cobalt prices are key estimates that are critical in the fair value 
of the Buy Back Options associated with the Royalty financing. 
In 2022 the Group issued $65m convertible loan notes which was secured to finance the construction of the Araguaia project. The con­
vertible loan is a hybrid financial instrument, whereby a debt host liability component and an embedded derivative liability component 
was determined at initial recognition. The conversion option did not satisfy the fixed for fixed equity criterion (fixed number of shares and 
fixed amount of functional currency cash) as the currency of the convertible loan notes is US Dollar and the functional currency of Hori­
zonte Minerals Plc and its share price is GBP. For convertible notes with embedded derivative liabilities, the fair value of the embedded 
derivative liability is determined first and the residual amount is assigned to the debt host liability. Details of the convertible loan notes 
are included in note 22.   
The future expected market share price of the Company and the volatility of the share price are the key estimates that are critical in the 
determination of the fair value of the embedded derivative and subsequently the debt host liability of the Convertible Loan Notes.
Fair value measurements recognised in the statement of financial position subsequent to initial fair value recognition can be classified 
into Levels 1 to 3 based on the degree to which fair value is observable. 
Level 1 – Fair value measurements are those derived from quoted prices in active markets for identical assets and liabilities.
Level 2 – Fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable 
for the asset or liability, either directly, or indirectly. 
Level 3 – Fair value measurements are those derived from valuation techniques that include inputs for the asset or liability that are not 
based on observable market data. 
Information relating to the basis of determination of the level 3 fair value for the buyback options and the convertible loan note embed­
ded derivative and consideration of sensitivity to changes in estimates is disclosed in note 21b) and note 22 respectively. Information 
relating to the level 2 designated hedge instrument is disclosed in note 14.
There were no transfers between any levels of the fair value hierarchy in the current or prior years. 
4 Critical accounting estimates and judgements

The preparation of the Financial Statements in conformity with UK adopted international accounting standards requires management 
to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and 
liabilities at the end of the reporting period and the reported amount of expenses during the year. Actual results may vary from the 
estimates used to produce these Financial Statements. 

Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations 
of future events that are believed to be reasonable under the circumstances. 
Significant items subject to such estimates and judgements include, but are not limited to:
Estimates
Company – Application of the expected credit loss model prescribed by IFRS 9
IFRS 9 requires the Parent company to make assumptions when implementing the forward-looking expected credit loss model. This 
model is required to be used to assess the intercompany loan receivables from the company’s Brazilian subsidiaries for impairment.
Arriving at the expected credit loss allowance involved considering different scenarios for the recovery of the intercompany loan receiv­
ables, the possible credit losses that could arise and the probabilities for these scenarios. The following was considered; the exploration 
project risk for Vermelho as well as the potential economics as derived from the PFS, positive NPV of the Araguaia projects as demon­
strated by the Feasibility Study, ability to raise the finance to develop the projects, ability to sell the projects, market and technical risks 
relating to the project, participation of the subsidiaries in the Araguaia projects. See note 34 for a discussion on the adjustment passed 
concerning the impairment loss.
Valuation of derivative financial instruments 
Valuing derivatives inherently relies on a series of estimates and assumptions to derive what is deemed to be a fair value estimate for 
a financial instrument. The royalty financing arrangement entered into by the Group includes a Buyback option, an embedded deriva­
tives which was valued using a Monte Carlo simulation method. This methodology of determining fair value is reliant upon estimations 
including the probability of certain scenarios occurring, the estimated production rate and timeline of production from the Araguaia and 
Vermelho projects, future nickel prices as well as discount factors. The most important estimates in determining the valuation of the 
Buyback option are the future nickel and cobalt prices and their price volatility. The sensitivity of the valuation to these estimates are 
considered in note 21b). 
The conversion option on convertible loan notes issued by the Group is an embedded derivatives which was valued using a Monte Carlo 
simulation method. This methodology of determining fair value is reliant upon estimations including the Company’s future share price 
volatility and GBP:USD exchange rate volatility on the conversion price. The sensitivity of the valuation to these estimates are considered 
in note 22).

Judgements
4.1 Impairment of exploration and evaluation costs and mine development property
Exploration and evaluation costs which relate solely to Vermelho have a carrying value at 31 December 2022 of US$12,834,249 
(2021: US$8,018,343). Each exploration project is subject to an annual review by either a consultant or senior company geologist to 
determine if the exploration results returned to date warrant further exploration expenditure and have the potential to result in an 
economic discovery. This review takes into consideration long-term metal prices, anticipated resource volumes and grades, permitting 
and infrastructure. In the event that a project does not represent an economic exploration target and results indicate there is no ad­
ditional upside, a decision will be made to discontinue exploration. The judgement exercised by management relates to whether there 
is perceived to be an indicator of impairment and that management have concluded that there is not, due to the recovery in the Nickel 
prices, favourable economics of the Pre-Feasibility Study as well as the fundamentals of the nickel market and expected supply gap in 
the mid-term. 
Mine development property which relates solely to Araguaia has a carrying value at 31 December 2022 of US$263,965,415 (2021: 
US$59,417,577) and is subject to an annual review by the management together with a consultant or a senior company geologist for 
impairment. The review takes into consideration long-term metal prices, anticipated resource volumes and grades, permitting, infra­
structure and project financing available to continue with the project construction. In the event that the project prospects are unfavour­
able or additional funding needs to be secured to complete the project construction a decision may be made to impair the project. The 
judgement exercised by management relates to whether there is perceived to be an indicator of impairment and that management have 
concluded that there is not, due to the recovery in the Nickel prices, favourable economics of the Feasibility Study, the fundamentals of 
the nickel market and expected supply gap in the mid-term and the financing secured for the project construction.
4.2 Contingent and deferred consideration
Contingent consideration has a carrying value of US$6,895,737 (2021: US$6,734,134) and deferred consideration has a carrying value 
of US$5,758,431 (2021: US$5,443,861) at 31 December 2022. There are two contingent consideration arrangements in place as at 
31 December 2022: 
	
~ Payable to Glencore in respect of the Araguaia acquisition - $5m 
	
~ Payable to Vale in respect of the Vale acquisition - $6m 

The deferred contingent consideration arrangement in place as at 31 December 2022 is payable to Companhia Brasileira de Alumino 
(CBA) in respect of plant equipment.
In prior years Management judged that the projects had advanced to a stage that it was probable that the consideration would be paid 
and so should be recognised in full. This remains the position. In addition, a key estimate in determining the estimated value of the 
contingent and deferred consideration for Glencore Vale and CBA  is the timing of the assumed date of first commercial production. 
Please refer to Note 20 for an analysis of the contingent and deferred consideration. 
4.3 Current and deferred taxation
The Group is subject to income taxes in numerous jurisdictions. Judgment is required in determining the worldwide provision for 
such taxes. The Group recognises liabilities for anticipated tax issues based on estimates of whether additional taxes will be due. 
Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will affect 
the current and deferred income tax assets and liabilities in the period in which such determination is made. 
Deferred tax liabilities are recognised in respect of fair value adjustments to the carrying value of intangible assets as a result of the 
acquisition of such assets. Deferred tax assets are recognised on tax losses carried forward to the extent that the realisation of the 
related tax benefit through future taxable profits is probable.  In determining whether a deferred tax asset should be recognised man­
agement must make an assessment of the probability that the tax losses will be utilized and a deferred tax asset is only recognised 
if it is considered probable that the tax losses will be utilized, this will only be once the operations have achieved nameplate capacity 
consistently over an extended period of time. 
Other estimates include but are not limited to future cash flows associated with assets, useful lives for depreciation and fair value of 
financial instruments.  
4.4 Accounting for the Araguaia royalty finance arrangement
The Group has a $25m royalty funding arrangement which was secured in order to advance the Araguaia project towards construc­
tion. The royalty pays a fixed percentage of revenue to the holder for production from the first 426k tonnes of nickel produced from 
the Araguaia project. The treatment of this financing arrangement as a financial liability, calculated using the effective interest rate 
methodology is a key judgement that was made by the Company in the prior year and which was taken following obtaining independ­
ent expert advice. The carrying value of the financing liability is driven by the expected future cashflows payable to the holder on the 
basis of the production profile of the mine property. It is also sensitive to assumptions regarding the royalty rate, which can vary 
based upon the start date for construction of the project and future nickel prices. The contract includes certain embedded derivatives, 
including the Buy Back Option which has been separated and carried at fair value through profit and loss. 
The future price of nickel and date of commencement of commercial production are key estimates that are critical in the determina­
tion of the carrying value of the royalty liability. 
The future expected nickel price and, volatility of the nickel prices are key estimates that are critical in the determination of the fair 
value of the Buy Back Option associated with the Royalty financing. 
Further information relating to the accounting for this liability, the embedded derivative and the sensitivity of the carrying value to 
these estimates is provided in note 21a) and 21b).
4.5 Accounting for the Vermelho royalty finance arrangement
The Group has a $25m royalty funding arrangement which was secured in order to advance a feasibility study and permitting work 
streams on the Vermelho project. The royalty pays a fixed percentage of revenue to the holder for production on the nickel and cobalt 
tonnes produced from the Vermelho project over the life of mine. The treatment of this financing arrangement as a financial liability, 
calculated using the effective interest rate methodology is a key judgement that was made by the Company in prior years on the Ara­
guaia Royalty and which was taken following obtaining independent expert advice. The carrying value of the financing liability is driven 
by the expected future cashflows payable to the holder on the basis of the production profile of the mine property. It is also sensitive to 
assumptions regarding the royalty rate, which can vary based upon the start date for construction of the project and future nickel and 
cobalt prices. The contract includes certain embedded derivatives, including the Buy Back Option which has been separated and carried 
at fair value through profit and loss.
The future prices of nickel and cobalt and the date of commencement of commercial production are key estimates that are critical in the 
determination of the carrying value of the royalty liability.
The future expected nickel and cobalt prices and volatility of such prices are key estimates that are critical in the determination of the fair 
value of the Buy Back Option associated with the Royalty financing.
Further information relating to the accounting for this liability, the embedded derivative and the sensitivity of the carrying value to these 
estimates is provided in note 21a) and 21b).
4.6 Accounting for the Convertible Loan Notes
The Group issued $65m convertible loan notes which was secured to finance the construction of the Araguaia project. The convertible 
loan is a hybrid financial instrument, whereby a debt host liability component and an embedded derivative liability component was de­
termined at initial recognition. The conversion option did not satisfy the fixed for fixed equity criterion (fixed number of shares and fixed 
amount of functional currency cash) as the currency of the convertible loan notes is US Dollar and the functional currency of Horizonte 
Minerals Plc and its share price is GBP.
For convertible notes with embedded derivative liabilities, the fair value of the embedded derivative liability is determined first and the 
residual amount is assigned to the debt host liability. 
The future expected market share price of the Company and the volatility of the share price are the key estimates that are critical in the 
determination of the fair value of the embedded derivative and subsequently the debt host liability of the Convertible Loan Notes. 
Further information relating to the accounting for this liability, the embedded derivative and the sensitivity of the carrying value to these 
estimates is provided in note 22 .
4.7 Determination of commencement of capitalisation of borrowing costs 
The date at which the Group commenced capitalisation of borrowing costs was determined to be the point at which the Araguaia Project 
moved forwards with undertaking an exercise of value engineering to get the project construction ready. This was deemed by manage­
ment to be at the start of 2020.
5 Segmental reporting
The Group operates principally in the UK and Brazil, with operations managed on a project-by-project basis within each geographical 
area. Activities in the UK are mainly administrative in nature whilst the activities in Brazil relate to exploration and evaluation work. 
The separate subsidiary responsible for the project finance for the Araguaia Project is domiciled in the Netherlands. The operations of 
this entity are reported separately and so it is recognised as a new segment. The reports used by the chief operating decision-maker 
are based on these geographical segments.

The foreign currency exchange gain for the year of US$8,482,457 (US$862,739 loss) arose from the translation of bank accounts 
and financing arrangements denominated in currencies other than the functional currency of the Groups' subsidiaries or parent 
company. This arose due to the Brazilian Real strengthening against the US Dollar and the Pound Sterling weakening against the 
US Dollar during the year.

(a) Exploration and evaluation assets
The exploration licences and exploration and evaluation costs relate to the Vermelho project. No indicators of impairment were identified 
during the year for the Vermelho project. 
Vermelho
In January 2018, the acquisition of the Vermelho project was completed, which resulted in a deferred consideration of $1,850,000 being 
recognised and accordingly the amount was capitalised to the exploration licences held within intangible assets shown above. 
On 17 October 2020 the Group published the results of a Pre-Feasibility Study on the Vermelho Nickel Cobalt Project, which confirms 
Vermelho as a large, high-grade resource, with a long mine life and low-cost source of nickel sulphate for the battery industry. 
The economic and technical results from the study support further development of the project towards a full Feasibility Study and 
included the following:
	
~ A 38-year mine life estimated to generate total cash flows after taxation of US$7.3billion;
	
~ An estimated Base Case post-tax Net Present Value1 (‘NPV’) of US$1.7 billion and Internal Rate of Return (‘IRR’) of 26%;  
	
~ At full production capacity the Project is expected to produce an average of 25,000 tonnes of nickel and 1,250 tonnes of cobalt 
per annum utilising the High-Pressure Acid Leach process;
	
~ The base case PFS economics assume a flat nickel price of US$16,400 per tonne (‘/t’) for the 38-year mine life;
	
~ C1 (Brook Hunt) cash cost of US$8,020/t Ni (US$3.64/lb Ni), defines Vermelho as a low-cost producer; and
	
~ Initial Capital Cost estimate is US$652 million (AACE class 4). 
Nothing has materially deteriorated with the economics of the PFS between the publication date and the date of this report and the 
Directors undertook an assessment of impairment through evaluating the results of the PFS along with recent market information relat­
ing to capital markets and nickel prices and judged that there are no impairment indicators with regards to the Vermelho Project. Nickel 
prices remain higher than they were at the time of the publication of the PFS and overall sentiment towards battery metals and supply 
materials have grown more positive over the current year. 
(b) Goodwill
Goodwill arose on the acquisition of Lontra Empreendimentos e Participações Ltda in 2010. The Directors have determined the recov­
erable amount of goodwill based on the same assumptions used for the assessment of the Lontra exploration project detailed above. 
As a result of this assessment, the Directors have concluded that no impairment charge is necessary against the carrying value of goodwill.

HORIZONTE MINERALS 2022 ANNUAL REPORT
HORIZONTE MINERALS 2022 ANNUAL REPORT
In December 2018, a Canadian NI 43-101 compliant Feasibility Study (FS) was published by the Company regarding the enlarged Ara­
guaia Project which included the Vale dos Sonhos deposit acquired from Glencore. The financial results and conclusions of the FS clearly 
indicate the economic viability of the Araguaia Project with an NPV of $401M using a nickel price of $14,000/t Ni. Nothing material had 
changed with the economics of the FS between the publication date and the date of this report and the Directors undertook an assess­
ment of impairment through evaluating the results of the FS along with recent market information relating to capital markets and nickel 
prices and judged that there are no impairment indicators with regards to the Araguaia Project. 
Impairment assessments for exploration and evaluation assets are carried out either on a project-by-project basis or by geographical area. 
The adjacent Araguaia/Lontra/Vila Oito and Floresta exploration sites (the Araguaia Project), together with the Vale dos Sonhos deposit 
acquired from Xstrata Brasil Mineração Ltda comprise a resource of a sufficient size and scale to allow the Company to create a signifi­
cant single nickel project. For this reason, at the current stage of development, these two projects are viewed and assessed for impair­
ment by management as a single cash generating unit. 
The mineral concession for the Vale dos Sonhos deposit was acquired from Xstrata Brasil Mineração Ltda, a subsidiary of Glencore Can­
ada Corporation, in November 2015. 
The NPV has been determined by reference to the FS undertaken on the Araguaia Project. The key inputs and assumptions in deriving the 
value in use were, the discount rate of 8%, which is based upon an estimate of the risk adjusted cost of capital for the jurisdiction, capital 
costs of $443 million, operating costs of $8,194/t Nickel, a Nickel price of US$14,000/t and a life of mine of 28 years. 
During the year further progress was made in the land acquisition process for the Araguaia project. US$1.7million of the land and ‘right 
of way’ purchases is included in trade and other payables as at 31 December 2022.
US$105million of the additions for the mine development property are prepayments to suppliers which have been paid in advance of 
delivery of mining equipment that is pre-fabricated offsite.

In January 2022 the Group’s Board approved the budget for the development of the Araguaia Ferronickel Project (Project). With the 
funding base being primarily US Dollars, the Project budget includes a significant portion of spend in local currency, the Brazilian Real 
(BRL). The Group and its senior lenders agreed to implement a foreign exchange hedging strategy that ensures that at least 70% of its 
BRL denominated capital expenditure to be incurred between 14 May 2022 and 31 March 2024 is hedged to reduce the exposure of 
future BRL foreign exchange risk.
The Group has therefore entered into a series of monthly non-deliverable forward transactions (“NDFs”) which will lock in a series of 
future USD: BRL rates based on the Group’s projected spend profile at the time of entering into those transactions. NDFs by definition 
are non-deliverable and so the Group would either pay or receive an amount of BRL to ensure that it ultimately achieves the hedged rate.
The effects of the cash flow non-deliverable forward contract hedging relationship are as follows:

17 Share-based payments
The Directors have discretion to grant options to the Group employees to subscribe for Ordinary shares up to a maximum of 10% of 
the Company’s issued share capital. One third of options are exercisable at each six months anniversary from the date of grant, such 
that all options are exercisable 18 months after the date of grant, other than the options issued on 12 July 2022. Options issued on 12 
July 2022 will vest in three tranches on the 12-month, 18-month and 28-month anniversaries after the date of grant (refer below for 
further information). All share options lapse on the tenth anniversary of the date of grant or the holder ceasing to be an employee of 
the Group. Should holders cease employment then the options remain valid for a period of 3 months after cessation of employment, 
following which they will lapse. Neither the Company not the Group has any legal or constructive obligation to settle or repurchase the 
options in cash.
Two employees exercised their share options on 11 April 2022 and 6 July 2022 respectively.
On 31 May 2022 the Group completed a share consolidation on the basis of 1 new share for every 20 existing shares. The number of 
share options and the exercise prices have been revised following the share consolidation.
The Group awarded new share options on 12 July 2022 (the “Award Date”) over 9,736,250 ordinary shares of £0.20 each in the capital of 
the Company to executives (PDMRs) and key personnel in the UK and Brazil. Each share option is exercisable in return for one ordinary 
share in the Company and will vest in three tranches on the 12-month, 18-month and 28-month anniversaries of the Award Date at a 
ratio of 25%, 25% and 50%, with exercise prices of £1.68, £1.72 and £1.76 for each one third of the Awards.

The options outstanding at 31 December 2022 had a weighted average remaining contractual life of 7.48 years (2021: 4.47 years). 
The fair value of the share options issued during the current financial year was determined using the Black-Scholes valuation model.
The expected volatility is based on historical volatility for one year prior to the date of grant. The risk-free rate of return is based on zero 
yield government bonds for a term consistent with the option life.

Other reserve 
The other reserve arose on consolidation as a result of merger accounting for the acquisition of the entire issued share capital of Hori­
zonte Exploration Limited during 2006 and represents the difference between the value of the share capital and premium issued for the 
acquisition and that of the acquired share capital and premium of Horizonte Exploration Limited. 
Merger Reserve 
During the year ended 31 December 2010 the Company acquired 100% of Teck Cominco Brasil S.A and Lontra Empreendimentos e Par­
ticipações Ltda. These acquisitions were effected by the issue of shares in Horizonte Minerals plc. These shares qualified for merger relief 
under section 612 of the Companies Act 2006. In accordance with section 612 of the Companies Act 2006 the premium on the shares 
issued was recognised in a separate reserve within equity called merger reserve. 
Currency translation differences relate to the translation of Group entities that have a functional currency different from the presenta­
tion currency (refer note 2.8). Movements in the translation reserve are linked to the changes in the value of the Brazilian Real against 
the US Dollar: the intangible assets of the Group are located in Brazil, and their functional currency is the Brazilian Real, which decreased 
in value against US Dollar during the year.

20. Contingent and deferred consideration
20.1 Contingent Consideration payable to Xstrata Brasil Mineração Ltda
On 28 September 2015 the Company announced that it had reached agreement to indirectly acquire through wholly owned subsidiar­
ies in Brazil the advanced high-grade Glencore Araguaia nickel project (GAP) in north central Brazil. GAP is located in the vicinity of the 
Company’s Araguaia Project. 
Pursuant to a conditional asset purchase agreement (Asset Purchase Agreement) between, amongst others, the Company and Xstrata 
Brasil Exploraçâo Mineral Ltda (Xstrata), a wholly-owned subsidiary of Glencore Canada Corporation (Glencore), the Company has agreed 
to pay a total consideration of US$8 million to Xstrata, which holds the title to GAP. The consideration is to be paid according the follow­
ing schedule; 
	
~ US$2,000,000 in ordinary shares in the capital of the Company which was settled by way of issuing new shares in 
the Company as follows: US$660,000 was paid in shares to a subsidiary of Glencore during 2015 and the transfer of the 
Serra do Tapa and Pau Preto deposit areas (together: SdT) during 2016 initiated the final completion of the transaction 
with a further US$1,340,000 shares in the Company issued. 
	
~ US$1,000,000 after the date of issuance of a joint Feasibility Study for the combined Araguaia & GAP project areas, to be 
satisfied in HZM Shares (at the 5 day volume weighted average price taken on the tenth business day after the date of such 
issuance) or cash, at the election of the Company. Of this $330,000 is due upon the inclusion of Vale dos Sonhos in a Feasibility 
Study and $670,000 for Serra do Tapa, during 2018 a Feasibility Study including Vale dos Sonhos was published and the consid­
eration settled by way of issuing 13,855,487 new Shares in the Company occurred during 2019. Serra do Tapa is not included in 
the current project plans, therefore management have concluded it’s not currently probable that the consideration for Serra do 
Tapa will be paid. This consideration is therefore not included in contingent consideration; and 
	
~ The remaining US$5,000,000 consideration will be paid in cash, as at the date of first commercial production from any of the 
resource areas within the Enlarged Project area. Following transfer of the concession for the VdS deposit area to a subsidiary of 
the Company, this has been included in contingent consideration payable.

HORIZONTE MINERALS 2022 ANNUAL REPORT
HORIZONTE MINERALS 2022 ANNUAL REPORT
The contingent consideration payable to Xstrata Brasil Mineração Ltda for the acquisition of the Araguaia project has a carrying value of 
US$2,470,215 at 31 December 2022 (31 December 2021: US$2,308,612). It comprises US$5,000,000 consideration in cash as at the 
date of first commercial production of ferronickel product (excluding the commissioning period) from any of the resource areas covered 
in the purchase agreement, i.e. Vale dos Sonhos (VDS) and Serra do Tapa (SDT). The key assumptions underlying the treatment of the 
contingent consideration of US$5,000,000 is a discount factor of 7.0% along with the estimated date of first commercial production from 
the VDS and SDT permits. 
During 2020 the Araguaia project entered the development phase and as a result borrowing costs including unwinding of discount on 
contingent consideration for qualifying assets are capitalised to the mine development asset. 
20.2 Contingent consideration payable to Vale Metais Basicos S.A.
	
~ On 19 December 2017 the Company announced that it had reached an agreement with Vale S.A (“Vale”) to indirectly acquire 
through wholly owned subsidiaries in Brazil, 100% of the advanced Vermelho nickel-cobalt project in Brazil (“Vermelho”).  
	
~ The terms of the Acquisition required Horizonte to pay an initial cash payment of US$150,000 with a further US$1,850,000 in 
cash payable on the second anniversary of the signing of the asset purchase agreement. This was paid by the Group in Decem­
ber 2019 and is no longer included in deferred consideration. 
	
~ A final payment of US$6,000,000 in cash is payable by Horizonte within 30 days of first commercial sale of product from Ver­
melho. Management have assessed that with the publication of the Pre-Feasibility Study during 2019 for the Vermelho project, 
there is a reasonable probability that the project will advance through to production and therefore recognised the contingent 
consideration within liabilities for the first time in 2019. 
The contingent consideration payable to Vale Metais Basicos S.A. for the acquisition of the Vermelho project has a carrying value of 
US$4,425,522 at 31 December 2022 (31 December 2021: US$4,425,522). It comprises US$6,000,000 consideration in cash as at the 
date of first commercial production from the Vermelho project and was recognised for the first time in December 2019, following the 
publication of a PFS on the project. The key assumptions underlying the treatment of the contingent consideration of US$6,000,000 is 
a discount factor of 7.0% along with the estimated date of first commercial production. The estimated first date of commercial produc­
tion was revised during the year from June 2026 to June 2027. This revision was considered necessary given the expected timelines 
for the feasibility study completion and thereafter commence with the Vermelho Project development which includes finance raising.
The finance costs in respect of this contingent consideration are expensed as the Vermelho project has not entered the construction phase.
20.3 Deferred consideration payable to Companhia Brasileiro de Aluminio
On 8 December 2021 the Group’s subsidiary Araguaia Niquel Metais Ltda (ANM) entered into an asset purchase agreement to purchase 
certain new and unused ferronickel processing equipment (the “Processing Equipment”) from Companhia Brasileira de Alumínio (“CBA”).
The Processing Equipment comprises the key components of a conventional rotary kiln electric furnace plant (“RKEF”), excluding the 
furnace, and is expected to provide meaningful synergies in relation to the development of the Araguaia ferronickel project. 
An upfront cost of US$600,000 is payable in cash on signing with a total consideration of up to US$7,000,000, with the balance payable 
upon the achievement of future milestones related to the development and operation of Araguaia. As part of the transaction CBA will 
continue to perform care and maintenance activities going forward until it is removed from the existing site. 
The total consideration of up to US$7 million payable by ANM will be paid according to the following schedule:
	
~ US$600,000 was paid on execution of the Agreement; 
	
~ US$950,000 is payable upon the removal of 80% of the Processing Equipment from CBA’s Niquelândia operations;
	
~ US$950,000 is payable upon reaching 50% completion of Araguaia plant construction;
	
~ US$1,150,000 is payable upon production at Araguaia reaching 90% of nameplate capacity for a period of 60 days, on 
average, and with up to 50% of such amount payable in Horizonte shares, at Horizonte’s election; and
	
~ US$3,350,000 is payable by Horizonte in three equal annual instalments with the first instalment due within 45 days of 
the first sale of ferronickel to a third party. Horizonte may choose to pay the outstanding balance of this amount at any 
time of its choosing with up to 50% of the total able to be paid in Horizonte’s shares, at Horizonte’s election.
In addition, the contract provides that each component of the Purchase Price shall be deemed immediately due and payable to the 
Seller at the long stop date of  December 31, 2027. The deferred consideration payable to CBA has a carrying value of US$5,758,431 at 
31 December 2022 (31 December 2021: US$5,443,861). The key assumptions underlying the treatment of the deferred consideration 
of US$7,000,000 is a discount factor of 7.0% along with the estimated date of completion of the project milestones as outlined above. 
The critical assumptions underlying the treatment of the contingent and deferred considerations are set out in note 4.2.

The change in estimate during 2021 relates revisions to the estimated payment date of the Xstrata Brasil Mineração Ltda contingent 
consideration  as a result of the start date of commercial production at the VDS and SDT areas being delayed. 
21 a) Royalty financing liability 
21 a.1) Araguaia royalty financing liability 
On 29 August 2019 the Group entered into a royalty funding arrangement with Orion Mine Finance (“OMF”) securing a gross upfront 
payment of US$25,000,000 before fees in exchange for a royalty, the rate being in a range from 2.25% to 3.00% and determined by the 
date of funding and commencement of major construction. The rate has been confirmed to be 2.95%. The royalty is paid over the first 
426k tonnes of nickel produced from the Araguaia Ferronickel project. The royalty is linked to production and therefore does not become 
payable until the project is constructed and commences commercial production. The agreement contains certain embedded derivatives 
which as per IFRS9 have been separately valued and included in the fair value of the financial instrument in note 21 b). 
The Royalty liability has initially been recognised using the amortised cost basis with an effective interest rate of 14.5%. When circum­
stances arise that lead to payments due under the agreement being revised, the group adjusts the carrying amount of the financial 
liability to reflect the revised estimated cash flows. This is achieved by recalculating the present value of estimated cash flows using the 
original effective interest rate of 14.5%. Any adjustment to the carrying value is recognised in the income statement. 
The carrying value of the royalty reflects assumptions on expected long term nickel price, update headline royalty rate as well as the tim­
ing of payments related to expected date of commencement of production and hence payment to be made under the royalty agreement.
The long-term nickel price used in the royalty valuation as at 31 December 2022 is US$18,721/t Ni (2021:US$ 16,945/t Ni). 
Management have sensitised the carrying value of the royalty liability for a US$1,000/t Ni increase/decrease in future nickel price the 
carrying value would change by US$2,682,547 (2021:US$2,711,505).

21 a.2) Vermelho royalty financing liability 
On 23 November 2021 the Group entered into a royalty funding arrangement with Orion Mine Finance (“OMF”) securing a gross upfront 
payment of US$25,000,000 before fees in exchange for a royalty, at a rate of 2.1%. The royalty rate will increase to 2.25% if substantial 
construction of the Vermelho Project has not commenced within 5 years of the closing date, 30 March 2022.  The royalty will be paid over 
the life of mine of Vermelho. The Royalty agreement has certain provisions to revise the headline royalty rate should there be change in 
the mine schedule and production profile prior to construction or if the resource covered in the Vermelho Feasibility Study is depleted. 
The royalty is linked to production and therefore does not become payable until the project is constructed and commences commercial 
production. The agreement contains certain embedded derivatives which as per IFRS9 have been separately valued and included in the 
fair value of the financial instrument in note 21 b). The royalty funds were received on 30 March 2022.
The Royalty liability has initially been recognised using the amortised cost basis with an effective interest rate of 17.66%. When cir­
cumstances arise that lead to payments due under the agreement being revised, the group adjusts the carrying amount of the financial 
liability to reflect the revised estimated cash flows. This is achieved by recalculating the present value of estimated cash flows using the 
original effective interest rate of 17.66%. Any adjustment to the carrying value is recognised in the income statement. 
The carrying value of the royalty reflects assumptions on expected long term nickel and cobalt prices, headline royalty rate as well as the 
timing of payments related to expected date of commencement of production and hence payment to be made under the royalty agreement. 
The assumption influencing the initial valuation of the carrying value of the Vermelho royalty is the long-term nickel price of US$17,756 
t/Ni (as at the initial recognition date 30 March 2022), the long-term cobalt price of US$53,355t/Co (as at the initial recognition date 30 
March 2022), and the royalty rate of 2.1%. The assumptions influencing the valuation at the period end date is the long-term nickel price 
of US$18,721 t/Ni, the long-term cobalt price of US$56,950 t/Co. The royalty rate has remained at 2.1%.
Management have sensitised the carrying value of the royalty liability by a change in the royalty rate to 2.25% and it would be 
US$2,925,856 higher and for a US$1,000/t increase/decrease in future nickel price and future cobalt price the carrying value would 
change by US$1,981,761.

21 b) Derivative financial asset
21 b.1) Araguaia derivative financial asset
The aforementioned agreement includes several options embedded within the agreement as follows:
	
~ If there is a change of control of the Group and the start of major construction works (as defined by the expenditure of in excess 
of $30m above the expenditure envisaged by the royalty funding) is delayed beyond a certain pre agreed timeframe the follow­
ing options exist:
•	 Call Option – which grants Horizonte the option to buy back between 50 – 100% of the royalty at a valuation that meets 
certain minimum economic returns for OMF;
•	 Make Whole Option – which grants Horizonte the option to make payment as if the project had started commercial produc­
tion and the royalty payment were due; and
•	 Put Option – should Horizonte not elect for either of the above options, this put option grants OMF the right to sell between 
50 – 100% of the Royalty back to Horizonte at a valuation that meets certain minimum economic returns for OMF.
	
~ Buy Back Option - At any time from the date of commercial production, provided that neither the Call Option, Make Whole 
Option or the Put Option have been actioned, Horizonte has the right to buy back up to 50% of the Royalty at a valuation that 
meets certain minimum economic returns for OMF. 
The directors have undertaken a review of the fair value of all of the embedded derivatives and are of the opinion that the Call Option, 
Make Whole Option and Put Option currently have immaterial values as the probability of both a change of control and project delay are 
currently considered to be remote. There is considered to be a higher probability that the Group could in the future exercise the Buy Back 
Option and therefore has undertaken a fair value exercise on this option.
The initial recognition of the Buy Back Option has been recognised as an asset on the balance sheet with any changes to the fair value 
of the derivative recognised in the income statement. It been fair valued using a Monte Carlo simulation which runs a high number of 
scenarios in order to derive an estimated valuation. 
The assumptions for the valuation of the Buy Back Option are the future nickel price of US$18,721/t Ni (2021:US$16,941/t Ni), the start 
date of commercial production in March 2024 (2021: May 2023), the prevailing royalty rate of 2.95% (2021: 2.95%), the inflation rate of 
2.22% (2021: 1.76%), and volatility of nickel prices of 39.7% (2021: 22.1%).
Sensitivity analysis 
The valuation of the Buyback option is most sensitive to future nickel price estimates and nickel price volatility.
A 15% adjustment to the estimated future nickel price would result in a variance between US$2.7million and US$3million in the valuation.
21 b.2) Vermelho derivative financial assets
Horizonte has the right to buy back 50% of the royalty on the first four anniversaries of closing (or on any direct or indirect change of 
control in respect of Vermelho up until the fourth anniversary of closing).
After the 4th anniversary, Horizonte has the right to buy back 50% of the royalty on any direct or indirect change of control in respect of 
Vermelho at a valuation that meets certain minimum economic returns for OMF.
The initial recognition of the Buy Back Option has been recognised as an asset on the balance sheet with any changes to the fair value of 
the derivative recognised in the income statement. It has been fair valued using a Monte Carlo simulation which runs a high number of 
scenarios in order to derive an estimated valuation. 
The assumptions for the valuation of the Buy Back Option are the future nickel price (US$18,721/t Ni), the future cobalt price (US$56,950/t 
Co), the production profile from 2027 to 2065, the expected royalty rate (2.1%), the inflation rate (2.22%), volatility of nickel prices (22.1%) 
and volatility of cobalt prices (28.0%). 
Sensitivity analysis 
The valuation of the Buyback option is sensitive to estimates for nickel and cobalt prices and their respective volatilities.
A 15% adjustment to the estimated future nickel and cobalt prices would result in a variance of US$3.7 million in the valuation.

22 Convertible loan notes
On 29 March 2022 the Company issued convertible loan notes to the value of US$65 million at an interest rate of 11.75% with interest 
accruing quarterly in arrears. The convertible loan notes were issued at a discount of 5.75%. The maturity date of the instruments is 
15 October 2032.
The convertible loan notes are unsecured and the noteholders will be repaid as follows:
	
~ Interest shall be capitalised until the Araguaia Project Completion date, estimated to be 31 December 2025 (subject to various 
technical operating tests being passed)
	
~ After Project Completion Date, interest shall be paid quarterly only if there is available cash (after the company meets its senior 
debt and other senior obligations)
	
~ After Project Completion Date, principal repayments (including accrued capitalized interest) shall be paid quarterly subject to 
available cash for distribution. In addition, a cash sweep of 85% of excess cash will apply on each interest payment date
	
~ Any amount outstanding on the CLN on the maturity date 15 October 2032, Horizonte is obliged to settle in full on 
the maturity date.
At any time until the Maturity Date, the Noteholder may, at its option, convert the notes, partially or wholly, into a number of ordinary 
shares up to the total amount outstanding under the Convertible Note divided by the Conversion Price. The Conversion Price is 125% of 
the Subscription Price of 0.07 pence (after share consolidation 1.40 pence converted to US$ at a rate of 1.3493). The Conversion Price 
is therefore US$1.89. After the equity fundraise that was completed on 8 November 2022 (refer to note 14) the conversion price was 
revised to £1.268 /US$1.71.

HORIZONTE MINERALS 2022 ANNUAL REPORT
The convertible loan is a hybrid financial instrument, whereby a debt host liability component and an embedded derivative liability 
component was determined at initial recognition. The conversion option did not satisfy the fixed for fixed equity criterion (fixed number 
of shares and fixed amount of functional currency cash) as the currency of the convertible loan notes is US Dollar and the functional 
currency of Horizonte Minerals Plc and its share price is GBP.
For convertible notes with embedded derivative liabilities, the fair value of the embedded derivative liability is determined first and the 
residual amount is assigned to the debt host liability.
The initial recognition of the embedded derivative conversion feature has been recognised as a liability on the balance sheet with any 
changes to the fair value of the derivative recognised in the income statement. It has been fair valued using a Monte Carlo simulation 
which runs a high number of scenarios in order to derive an estimated valuation. The Monte Carlo simulation was performed at the 
transaction date 29 March 2022 and at the year-end date 31 December 2022.
The assumptions for the valuation of the conversion feature (per the Monte Carlo simulation) at initial recognition are the Horizonte 
Minerals Plc future share price volatility (60.3%), GBP: USD exchange rate volatility (11.1%) on the conversion price. At the year end date 
the share price volatility assumption was 42.9% and the GBP: USD exchange rate volatility assumption 10%.
At 29 March 2022 the fair value of the conversion feature was calculated (per the Monte Carlo simulation) as US$36,458,088. The pro­
ceeds received was US$ 61,262,500 and thus the residual allocated to the debt host liability was US$24,804,412.
The debt host liability will be accounted for using the amortised cost basis with an effective interest rate of 34%. The effective interest 
rate is recalculated after adjusting for the transaction costs and the discount of 5.75%. The Group will recognise the unwinding of the 
discount at the effective interest rate, until the maturity date, the carrying amount at the maturity date will equal the cash payment 
required to be made.
The directly attributable transaction costs amounted to US$2,347,041 which was allocated proportionately to the embedded derivative 
(US$1,396,754) and the convertible loan notes liability (US$ 950,287). The embedded derivative transaction costs were recognised in 
profit and loss, whereas the convertible loan liability transaction costs were deducted from the financial liability carrying amount.
After the fifth anniversary of the closing date, Horizonte shall have a one-time right to redeem the Convertible Notes, in whole, at 105% 
of the par value plus accrued and unpaid interest in cash if:
1.	The thirty-business day VWAP of Horizonte shares exceeds 200% of the Conversion Price and the average daily liquidity of the Com­
pany’s shares (across all relevant exchanges) exceeds US$2.5 million per trading day over the prior 30 trading days; or
2.	There is a change of control.
Management have assessed the likelihood of the above events occurring is highly improbable and thus the value of the redemption right 
is immaterial and was thus not considered in the valuation of the instrument.
Sensitivity analysis – Conversion feature derivative 
The valuation of the conversion feature derivative is sensitive to the Company’s equity price and share price volatility. A 15% adjustment 
on the Company’s equity price results in a variance of between US$7.6million and US$8.3million in the valuation. A 30% adjustment on 
the equity volatility results in a variance of US4.9million.

23 Cost overrun facility
On 30 November 2022, the Group satisfied all conditions precedent in relation to the cost overrun facility (COF) and had received all COF 
funds from Orion. The COF benefits from the same security package as the senior debt facility but will be subordinated to the senior 
debt facility. Access to the COF funds is restricted and will only be available in the case of a cost overrun against the Araguaia Project 
construction schedule and budget, subject to certain conditions including:
1.	90% of the funding from the Equity Fundraise and Convertible loan notes have been invested in the construction 
of the Araguaia Project
2.	A gearing ratio of 70:30 being met
The COF is US$25million with an interest rate of 13% and a maturity date of 15 October 2032. Interest will be calculated quarterly and be 
payable in arrears at the end of each interest period – March 31, June 30, September 30 and December 31. The first interest period was 
30 November to 31 December 2022. The initial principal repayment date is 31 March 2025. 3.23% of the outstanding principal amount 
will be paid at each quarter end date starting from 31 March 2025.
The COF will be accounted for using the amortised cost basis with an effective interest rate of 15%. The effective interest rate is recalcu­
lated after adjusting for the transaction costs. The Group will recognise the unwinding of the discount at the effective interest rate, until 
the maturity date, the carrying amount at the maturity date will equal the cash payment required to be made.

24 Senior debt facility
On 15 March 2022 the Group entered into legally binding documentation including a comprehensive intercreditor agreement and 
loan agreements with two export credit agencies in relation to its senior secured project finance debt facility of  US$346.2 mil­
lion. The senior debt facility was executed between Araguaia Niquel Metais LTDA, and a syndicate of international financial institu­
tions, being BNP Paribas, BNP Paribas Fortis, ING Capital LLC, ING Bank N.V., Natixis, New York Branch, Société Générale and SEK 
(Swedish Export Credit Corporation). 
The senior debt facility includes the following:
	
~ Commercial senior facility of US$200,000,000 provided by the Senior Lenders;
	
~ ECA facility of US$74,562,000 guaranteed by EKF (Denmark’s Export Credit Agency);
	
~ ECA facility of US$71,638,000 guaranteed by Finnvera plc (Finland’s Export Credit Agency);

On 7 December 2022, the Group satisfied all conditions precedent for the first utilisation under the senior debt facility of US$346.2 mil­
lion. The first utilisation was for US$5million.
The interest rate on the ECA facility is calculated according to this formula : Margin + Term SOFR (Secured Overnight Financing Rate) + 
Baseline Credit Adjustment Spread (CAS). The ECA Facility margin is 1.8%. The Term SOFR was the first interest period was 4.21714% and 
the Baseline CAS 0.11448%. The ECA facility interest rate was therefore 6.13162% at 31 December 2022.
The interest rate on the Commercial facility is calculated according to this formula : Margin + Term SOFR (Secured Overnight Financing 
Rate) + Baseline Credit Adjustment Spread (CAS). The Commercial Facility margin is 4.75%. The Term SOFR was the first interest period 
was 4.21714% and the Baseline CAS 0.11448%. The ECA facility interest rate was therefore 9.08162% at 31 December 2022.
Interest will be calculated quarterly and be payable in arrears at the end of each interest period – March 31, June 30, September 30 and 
December 31. The first interest period was 7 to 31 December 2022. The initial principal repayment date is 31 March 2025. The outstand­
ing principal amount will be paid according to the repayment schedule at each quarter end date starting from 31 March 2025. 
The final maturity date on the Commercial Facility is 15 July 2030. The final maturity date on the ECA Facility is 15 July 2032.

The ECA and Commercial Facilities will be accounted for using the amortised cost basis with effective interest rates of 12.25% and 11.57% 
respectively. The effective interest rate is recalculated after adjusting for the transaction costs. The Group will recognise the unwinding 
of the discount at the effective interest rate, until the maturity date, the carrying amount at the maturity date will equal the cash pay­
ment required to be made. 
The Senior Debt Facility is secured via a comprehensive security package which includes:
	
~ Pledge of shares in the Araguaia Níquel Metais Ltda. (the  “Borrower”);
	
~ Pledge of shares of the guarantors (other than Horizonte Minerals plc);
	
~ First ranking security over all of the Araguaia Project’s assets (including its mineral rights);
	
~ Assignment of insurance policies;

25 Environmental rehabilitation provision
Environmental rehabilitation provision relates to the estimated cost of returning the Araguaia Project mining property to its original 
state at the end of the life of mine in accordance with the Brazilian legislation. The cost is recognised as part of the Mine Development 
Asset and will be depreciated over the life of the mine. The main uncertainty relates to estimating the cost that will be incurred at the 
end of the life of mine. The costs have been estimated based on a mine closure report prepared by a third party expert taking into con­
sideration the environmental disturbance to date. The cost was inflation adjusted over the life of mine using inflation projections from 
reputable Brazilian financial institution and then discounted to its present value at 8%.

Impairment provisions for receivables and loans to related parties are recognised based on using the general approach to determine if 
there has been a significant increase in credit risk since initial recognition and whether the receivables and loans are credit impaired in 
accordance with IFRS9. 
The loan to the subsidiary companies, are classified as repayable on demand. IFRS 9 requires consideration of the expected credit risk 
associated with the loans. 
As part of the assessment of expected credit losses of the intercompany loan receivable, the Directors have assessed the cash flows 
associated with a number of different recovery scenarios. This included consideration of the:
	
~ Exploration and development project risk, 
	
~ positive NPV of the Araguaia project as demonstrated by the Feasibility Study
	
~ positive NPV of the Vermelho Nickel Cobalt Project demonstrated by the Pre-Feasibility Study
	
~ ability to raise the finance to develop the projects
	
~ ability to sell the projects
	
~ market and technical risks relating to the projects
	
~ participation of the subsidiaries in the Araguaia project

The directors have concluded that certain amounts may not be fully recovered giving rise to the expected credit loss adjustment. 
After taking into consideration all of the above factors the rate of expected credit loss varies from 30% (2021:30%) for the receivables 
from HM Brazil and 15% (2021:15%) for the Vermelho Project. The loss on default on receivables related to the Araguaia Project is min­
imal, which is consistent with the view taken in the prior year. The expected credit loss assessment for HM Brazil considers Araguaia’s 
construction progress and improving prospects for Vermelho. The credit loss allowance was assessed at the date of 31 December 
2022. The expected credit loss for Champol (IOM) Ltd was adjusted to US$1,270,496 (2021: US$1,134,309) and an expected credit loss 
allowance was recognised for Battery Material Services B.V. of US$127,191. The expected credit loss allowance for HM Brazil (IOM) Ltd 
remained unchanged. The change in the allowance is due to the USD currency translation.

36 Contingent Liabilities
Other Contingencies
The Group believes that there are no substantive financial claims and legal proceedings against it as at 31 December 2022. As a result, 
no provision and no disclosure has been made in these financial statements for the year ended 31 December 2022.
37 Parent Company Guarantee
Horizonte Minerals plc has, together with other group companies, provided a parent guarantee on the following funding arrangements:
1.	To Orion Mine Finance related to the $25 Million Royalty Financing arrangements granted by Nickel Production Services B.V. in 
respect of the project owned by Araguaia Níquel Metais Ltda.
2.	To Orion Mine Finance related to the $25 Million Royalty Financing arrangements granted by Battery Materials Services B.V. in 
respect of the project owned by Trias Brasil Mineração Ltda 
3.	To Orion Mine Finance related to the $25 Million cost overrun facility (COF) granted to Araguaia Níquel Metais Ltda (Borrower)  
4.	To the Senior Lenders (BNP Paribas, BNP Paribas Fortis, ING Capital LLC, ING Bank N.V., Natixis, New York Branch, Société 
Générale and SEK(Swedish Export Credit Corporation)) related to the $346.2 Million senior debt facility granted to Araguaia 
Níquel Metais Ltda (Borrower)
The royalty payments are conditional upon entering into commercial production and therefore cannot become due until this is achieved. 
Interest on the loan facilities (COF and Senior Debt) will be calculated quarterly and be payable in arrears at the end of each interest period 
– March 31, June 30, September 30 and December 31. The end of the first interest period for both facilities was due 31 December 2022. 
The initial principal repayment date is 31 March 2025. The outstanding principal amounts will be paid according to the repayment sched­
ules at each quarter end date starting from 31 March 2025. 
Horizonte Mineral Plc's obligation to pay under the guarantee only arises if the grantors of the royalties, the borrower in the loan facil­
ities or any of the other provider of a parent guarantee fails to make any payment under the agreements. The Company also entered 
into a comprehensive intercreditor agreement, which establishes how the Senior Lenders and Orion (as the COF Lender and Royalty 
Holder) will consult with each other before exercising rights and remedies available to them under their respective security and finance 
documents. The Company considers the probability of such scenarios to be minimal at the current stage of the business’ development 
and therefore any fair value assessment of such potential financial liability has been deemed to be immaterial.
38 Events after the reporting date
Non-adjusting events after the reporting date
On 27 February 2023, the Group announced that it had drawn down US$50million from it senior secured project finance debt facility 
of US$346.2million.
