CRITICAL MINERALS FOR A SUSTAINABLE FUTURE
The global push towards electrification and reduction in fossil fuels 
consumption  represents  the  most  significant  structural  change  in 
global energy markets since the Industrial Revolution. 
A  sustainable  world  will  require  a  new  suite  of  minerals  –  critical 
minerals for a sustainable future.

Astron 2023 Annual ReportRARE EARTHS
To  meet  global  emissions  targets  the  International  Energy  Agency  has  estimated 
that, by 2030, electric vehicles will need to represent more than 60% of new vehicles 
sold  globally  and  that  wind  electricity  generation  capacity  is  required  to  increase 
annually by 17%. 
In these circumstances, the global demand for rare earths is expected to increase three and a half fold by 2030 and experience 
a further doubling in the period from 2030 to 2040. 
Astron’s Donald Rare Earth and Mineral Sands Project, with its significant size and advanced regulatory approvals, represents a 
significant source of rare earth minerals – one of a handful of deposits that is able to be developed within a short time frame. 
5
MINERAL SANDS 
In addition to being a globally significant rare earths project, the Donald Project, with 
the largest zircon resources in the world, is also a major potential source of zircon 
and  titanium  minerals. This  diverse  mineral  characterisation  distinguishes  Donald 
from all other development-ready mineral sands and rare earth projects. 
Based on the Phase 1 Donald Project Definitive Feasibility Study, which was released on 26 April 2023, the project has 
a revenue split of 57% rare earths and 43% mineral sands over its greater than 40-year mine life. 
With over 35 years of market experience in mineral sands downstream processing, Astron is looking forward to 
leveraging its strong market connections and knowledge in the development of the Donald Project.

Donald Highlights
Astron’s  prime  focus  is  on  the  development  of  the  Donald  Rare  Earth  and  Mineral 
Sands Project (Donald Project) in regional Victoria.
Over  the  last  financial  year,  Astron  made  significant 
strides towards the development of this project, including 
reviewing the scope of the Project to maximise capital 
efficiency, the execution of an updated memorandum 
of  understanding  with  the  local  shire,  the  release  of 
the Phase 1 Donald Project Definitive Feasibility Study, 
and the updated Ore Reserves and pre-feasibility study, 
covering  Phase  2  of  the  project.  These  are  concrete 
milestones towards the construction of what will be a 
globally significant critical minerals operation.
Project Re-Scope 
A  review  of  the  Donald  Project’s  parameters  was 
undertaken  during  the  year.  The  purpose  was  to 
establish  the  least-risk  path  to  commercialisation  for 
Phase  1.  This  has  resulted  in  capital  efficiencies  for 
Phase 1 while maintaining flexibility to deliver additional 
value from subsequent phases. Importantly, the Phase 
1  Donald  Project  is  financially  viable  as  a  standalone 
project and is not dependent on subsequent phases to 
deliver attractive returns. Updated operations for mining 
phases are detailed on pages 23-25.
Memorandum of Understanding 
A  memorandum  of  understanding  was  signed  with 
Yarriambiack Shire Council to support the development 
of  the  project  and  deliver  related  benefits  to  the  local 
community. A large portion of the Phase 1 project area 
is located within Yarriambiack Shire.
Mineral Resource and Reserve  
Updates
Two new Ore Reserve estimates were released during 
the  year.  These  cover  the  mining  licence  MIN5532, 
which  is  the  site  of  the  Phase  1  project,  and  retention 
licence RL2002, which is the proposed site of the Phase 
2 project. The outcome has been an increase in Reserves 
for both areas and an increase in the Mineral Resources 
contained  within  MIN5532. The  Ore  Reserves  updates 
increased the total Donald Project Ore Reserve by 37% 
to 825Mt with an increase in heavy mineral Reserves of 
29% to 36.9Mt.
Phase 1 Definitive Feasibility Study
Astron  released  a  Definitive  Feasibility  Study  (DFS)  for 
the  Phase  1  Project  on  26  April  2023.  It  was  based  on 
a  complete  technical,  environmental,  logistical  and 
economic  evaluation  of  the  project  and  detailed  the 
extensive  work  carried  out  in  de-risking  operations 
on  the  MIN5532  mining  licence.  The  DFS  supports  a 
substantial return on investment with high confidence 
based  on  AACE  Class  2  capital  expenditure  estimates. 
All  main  regulatory  approvals  are  completed  or  well 
advanced in preparation for a Final Investment Decision 
(FID)  planned  for  1H  2024  and  first  production  in  1H 
2026.
Phase 2 Pre-Feasibility Study 
for 
The  Pre-feasibility  study  (PFS)  for  Phase  2  operations, 
to  be    established  on  retention  licence  RL2002,  was 
released  on  27  June  2023  and  shows  the  significant 
the  next  phase  of  project 
potential  upside 
development. Phase 2 operations involve a duplication 
of  Phase  1  mining  operations  with  the  addition  of  a 
mineral separation plant (MSP) which is sized to process 
the  heavy  mineral  concentrate  (HMC)  from  both  the 
Phase  1  and  the  Phase  2  Projects  and  produce  final 
zircon and titania products on-site. Together, the Phase 
1 and Phase 2 projects utilise about 43% of the Donald 
Project Mineral Resources over a combined mine life of 
58 years.
The  combined  Phase  1  and  Phase  2  Donald  Project  is 
forecast to generate an after tax NPV of $2.2 billion, at an 
IRR of 30.3%. Phase 2 construction is projected to start 
in  2029,  with  commissioning  leading  to  commercial 
operations towards the end of 2030. It is expected that 
the  equity  requirements  for  Phase  2  will  be  largely 
funded  through  internally  generated  cashflows  from 
Phase 1.

FROM THE CHAIRMAN
Dear Shareholder 
Astron  made  significant  progress  towards  the  commercial  development  of  the 
Donald Rare Earth and Mineral Sands Project during the year ended 30 June 2023. 
This has been made possible through the dedication and hard work of our people, 
the support of the community in which we work, and the continuing interest and 
support of our shareholders..
Donald’s development comes 
at  a  time  of  intense  public 
interest  in  critical  minerals. 
Rare  earth  elements,  as  well 
as being essential to the clean 
energy  transition,  are  crucial 
components in a wide range of 
high-tech  products  including 
and 
defence, 
electric  motor  applications. 
Zircon  and  titanium  minerals  are  vital  ingredients  in 
global  infrastructure,  urbanisation  and  construction. 
These  minerals  are  facing  supply-chain  challenges 
that  can  only  be  addressed  through  the  development 
of  new  projects.  The  Donald  Project,  with  a  granted 
mining  licence,  a  positively  assessed  Environmental 
Effects Statement and a world leading resource is in a 
unique position to meet these challenges.
aerospace 
The  development  philosophy  for  Phases  1  and  2  of 
the  Donald  Project  is  to  minimise  execution  risk  and 
ensure  the  timely  and  efficient  delivery  of  the  project 
through  the  application  of  well-proven,  conventional 
technologies, best practice environmental management 
and honest community engagement.
The most important achievement for the year was the 
completion of the Definitive Feasibility Study (DFS) for 
Phase  1  of  the  Donald  Project  which  confirmed  that 
the  project  was  both  technically  and  economically 
robust. Importantly, Phase 1 operations can stand alone 
economically  and  are  not  dependent  on  subsequent 
stages of development to provide attractive shareholder 
returns. The DFS provides the foundation for developing 
the project financing plan, progressing detailed product 
off-take  discussions,  advancing  construction  and 
operational planning, and finalising regulatory approvals 
in anticipation of a construction start in the second half 
of 2024 and first production in the first half of 2026.
The Pre-Feasibility Study (PFS) for Phase 2 of the Donald 
Project, also completed during the year, confirmed the 
project’s place as a Tier-1 rare earth and mineral sands 
project  of  long-term  global  significance.  Construction 
for Phase 2 of the project is planned to commence in 
2029  with  first  production  towards  the  end  of  2030. 
Furthermore,  the  utilisation  of  just  over  43%  of  the 
Donald  Project  Mineral  Resource  over  the  combined 
Phase  1  and  Phase  2  projects’  58-year  life  is  a  clear 
indication of the potential for further value creation by 
way of scale expansion as well as the production of a 
wide range of materials that are essential to life in the 
21st century.
Based  on  the  DFS,  with  a  capital  cost  of  $364  million 
(real,  2023  AUD),  Phase  1  operations  generate  an 
average  annual  revenue  of  $314  million  and  return  an 
average  annual  EBITDA  of  $148  million  over  its  41.5-
year life. The PFS for the combined Phase 1 and Phase 2 
operations indicated that, for an additional investment 
of $566 million, the project generates an average annual 
revenue of $678 million and returns an average annual 
EBITDA of $363 million over its 58-year life. The revenue 
to cash cost (RCC) ratio of 2.15 for the combined project 
is  anticipated  to  be  in  the  first  quartile  of  the  RCC 
curve for similar projects. It is a very strong indication 
of  Donald’s  robust  economics  as  well  as  its  ability  to 
withstand adverse commodity price movements.
Other important achievements through the year included 
the execution of a memorandum of understanding with 
the  Yarriambiack  Shire  Council,  the  appointment  of  a 
debt  funding  advisor,  the  commencement  of  detailed 
discussions  with  potential  product  off-take  partners 
and  the  preparation  of  a  work  plan  for  submission  to 
Victorian Government regulators.
The  memorandum  of  understanding  with 
the 
Yarriambiack Shire Council provides for Astron and the 
shire  to  work  cooperatively  to  maximise  the  mutually 
beneficial  community  and  economic  outcomes  from 
the project. 
12
Astron 2023 Annual Report 
The appointment of a debt advisor to assist with project 
financing  arrangements  was  a  significant  milestone; 
with  its  attractive  margins  and  long  life,  it  is  expected 
that the project will be able to secure debt funding on 
favourable terms. 
While Astron commenced the process of engagement 
with  potential  product  off-take  partners  in  the  early 
stages of project evaluation, the completion of the DFS 
has  facilitated  the  start  of  detailed  discussions  with  a 
number  of  parties  with  the  goal  of  securing  firm  off-
take agreements prior to the start of construction. 
In  order  to  commence  construction,  Astron  must 
also agree the terms of a work plan with the Victorian 
Government. The  work  plan  describes  the  nature  and 
scale  of  the  proposed  mining  activities,  identifies  and 
assesses all risks the works may pose to the environment 
and  to  the  public,  details  the  nature  of  community 
engagement, and includes a risk management plan for 
the purpose of eliminating or minimising identified risks 
and  monitoring  performance.  The  Company  is  very 
advanced towards finalisation of the work plan.
A major focus for the year, and subsequently, has been 
the building of the Astron team to progress the Donald 
Project  through  development,  construction  and  into 
operations. We are fortunate that, in having a world class 
project in an exciting sector of the minerals industry, we 
are able to attract people of the highest calibre.
The  Company’s  mineral  processing  operations 
in 
Yingkou,  China,  following  a  COVID-19  pandemic-
related  operational  hiatus  through  a  large  portion  of 
the  past  two  years,  has  upgraded  processing  facilities 
and is negotiating feedstock arrangements with several 
large international customers with a view to resuming 
full scale operations before the end of 2023. The Mining 
Licence  for  the  Niafarang  Mineral  Sands  project  in 
Senegal was renewed during the year and the Company 
is  pursuing  farm-out  opportunities  to  enable  the 
commencement of operations there without exposure 
to additional financial risk.
The  year  just  completed  has  required  considerable 
efforts  from  all  members  of  the  Astron  team.  We  are 
extremely grateful for their commitment and hard work.

Astron 2023 Annual Report 
FROM THE MANAGING DIRECTOR
The Donald Project is a long-life mining asset, comprising a world class reserve of rare 
earths, zircon and titanium minerals with the potential to generate significant value 
through low-risk conventional mining and heavy mineral processing operations. 
The  Phase  1  Donald  Project 
Definitive Feasibility Study (DFS), 
which  was  released  in  April 
2023,  confirmed  Donald  as  a 
Tier 1, globally significant critical 
minerals project. The DFS is the 
culmination  of  many  years  of 
metallurgical  testing,  detailed 
design 
engineering, 
community  engagement  and 
regulatory approvals.  
and 
Economically,  the  Phase  1  project  is  expected  to 
deliver  an  NPV8  of  $852  million  on  an  initial  capital 
investment  of  $364  million.  Average  annual  free  cash 
flow  is  estimated  at  $110  million  per  annum  for  the 
first  five  years,  and  $103  million  per  annum  over  the 
remainder of the 41.5-year mine life. For a project that 
generates impressive long-term value it has a relatively 
short payback period of under four years to be followed 
by  many  decades  of  mining  operations  to  drive 
sustainable, long-term investment returns. The Project’s 
return  profile  is  attractive  and,  based  on  conservative 
estimates, delivers a post-tax and inflation-adjusted real 
internal rate of return of 25.8%. 
Importantly,  the  Phase  1  project  demonstrates  a  small 
portion of the full potential of the Donald Project. Once 
operational,  Phase  1  cash-flows  are  anticipated  to 
be  applied  to  the  equity  requirements  of  the  Phase  2 
project – for which the indicative project economics (at 
PFS  level)  show  an  incremental  NPV  of  $1.4B,  and  an 
extension  of  the  Phase  1  plus  Phase  2  mine  life  from 
41.5  years  to  58  years  delivering  approximately  twice 
the Phase 1 rates of production. The Donald Project will 
allow Astron to be a part of the global critical minerals 
landscape for many decades.
Excitement  continues  to  build  around  applications 
of  rare  earths  as  they  are  recognised  as  the  building 
blocks for the global shift towards electric vehicles and 
renewable energy. A 3MW wind turbine uses close to 40 
kilograms of rare earths and, if the world is to achieve 
its emissions targets, rare earth demand must increase 
significantly.
The  zircon  component  of  Donald’s  reserves,  a  high 
proportion of which has premium quality characteristics, 
will  make  a  significant  contribution  to  the  ceramics 
markets where demand continues to grow due to the 
continuing global urbanisation trend. 
Existing  rare  earths  and  zircon  supplies  are  both 
expected  to  be  constrained  by  2026,  when  Donald  
Phase  1  is  planned  to  be  in  production.  Donald’s 
proposed  scale  and  development  timing  are  crucial 
not  only  to  supporting  the  energy  transition,  but  also 
to  meeting  the  supply  requirements  for  the  zircon 
industry, for which a large proportion of current supply 
is expected to deplete over the next 3 to 5 years. 
Personnel Appointments
With  the  significant  advances  made  to  the  Donald 
Project  through  the  year,  Astron  has  increased  its 
internal  capability  with  the  addition  of  several  highly 
skilled professionals. In October 2022, Greg Bell joined as 
Chief Financial Officer; Greg has experience in executive 
roles at international mineral sands companies and has 
been  integral  to  our  work  in  completing  the  recent 
feasibility studies and engaging in offtake and financing 
negotiations.  In  May  2023,  Jessica  Reid  joined  as  the 
General  Manager  of  Sustainability;  Jessica,  who  has 
extensive experience in navigating regulatory pathways, 
is  leading  our  efforts  on preparing  and  submitting the 
mining  work  plan.  The  Company  has  also  employed 
Karen Shelton as HR Manager and Samantha Flockhart 
as  Commercial  Manager  to  ensure  that  it  is  well-
prepared for the upcoming Project construction period.
Social Licence
Astron  is  particularly  proud  of  its  strong  standing  in 
the  local  community  which  it  has  cultivated  over 
many  years.  We  look  forward  to  continuing  to  work 
constructively  with  local  shire  councils  to  bring  long-
term economic benefits to the region.  
15
          
FROM THE MANAGING DIRECTOR
Next Steps – Donald Project
Looking  ahead  to  Financial  Year  2024,  there  are  four 
key  work  areas  being  addressed  in  taking  the  Donald 
Project to construction:
1.   Obtaining  final  approvals  for  the  Phase  1  project  - 
All  key  regulatory  approvals  for  Phase  1  have  been 
obtained  apart  from  the  Mining  Work  Plan.  It  is 
anticipated  that  this  will  be  submitted  in  2H  2023, 
and approved in 1H 2024.
2.   Obtaining  project  off-takes  for  the  Phase  1  project 
products  –  given  the  positive  market  dynamics 
and  strong  anticipated  product  quality,  Astron  has 
received significant interest in both its REEC and the 
HMC  product.  Term  sheet  execution  is  planned  for 
2H 2023. 
3.   Finalising project engineering and project contracts 
–  the  Astron  team  has  completed  the  DFS  to  an 
American  Association  of  Cost  Estimators  (AACE) 
level 2 estimate for both capital and operating costs. 
This  provides  the  basis  for  key  contract  tendering, 
which has commenced.
4.   Obtaining  project  financing  –  including  debt  and 
equity. Astron is aiming to fund the Phase 1 execution 
investment with a split of 60% debt and 40% equity. 
ICA Partners have been appointed as our debt advisor 
to  secure  appropriate  debt  financing  to  support 
construction. ICA Partners are a globally recognised 
resource  specialist  firm,  experienced 
in  critical 
mineral  projects’  financing.  Market  soundings  of 
potential financiers has been completed with strong 
interest from domestic and foreign institutions.

Astron 2023 Annual Report 
China
Gambia
As  outlined  in  previous  years,  in  2015  Astron  was 
awarded damages through an International Centre for 
Settlement of Investment Disputes (ISID) determination 
in  relation  to  the  Gambian  Government’s  seizure  of 
the Astron-Carnegie minerals sands project in Gambia. 
Recovery  of  the  initial  award  of  approximately  A$32 
million  continues  to  be  slow,  however  the  Company 
has  entered  into  a  litigation  funding  agreement  to 
expedite  the  recovery  of  this  award  at  no  further  cost 
to  the  Company.  During  the  year,  correspondence  in 
relation to the claim was sent to government officials in 
Gambia as well as to the International Monetary Fund.  
The  Company  will  continue  to  vigourously  pursue 
recovery of the outstanding amount.
I  wish  to  express  my  gratitude  to  members  of  our 
team and our contractors for their hard work over the 
previous year. I look forward, with great excitement, to 
the year ahead to bring to life a world-scale deposit. To 
my  Chairman,  George  Lloyd,  and  my  fellow  directors, 
I  extend  my  appreciation  for  your  dedication  to  the 
interests of the Company and its shareholders. 
Tiger Brown 
Managing Director
FY2023  was  a  challenging  year  for  Astron’s  Chinese 
operations. Continuing Covid-19 restrictions, including 
serious  lockdowns  experienced  across  major  cities  in 
the  first  half  of  the  financial  year,  and  the  on-going 
industry re-opening difficulties in the latter half of the 
financial  year  contributed  partly  to  the  lower  revenue 
for the year, which dropped from $19.0m in FY2022 to 
$14.5m in 2023. In addition, supply chain difficulties, and 
difficulties in sourcing concentrate product meant that 
a larger proportion of the revenue this year was derived 
from relatively low margin trading activities, rather than 
from processing plant operations. 
A  business  review  of  the  Chinese  operations,  which 
considered  among  other  things  the  difficulties  in 
securing  long-term  feedstock,  led  to  a  change  in 
operating  strategy  with  the  objective  of  opening  up 
the  plant  to  a  wider  range  of  concentrate  feedstocks 
(including in preparation for Donald HMC). This resulted 
in the installation of new separation spirals in the mineral 
separation plant and has made a positive contribution 
towards  securing  a  number  of  long-term  feedstock 
supply  arrangements.  The  new  process  flowsheet  is 
being commissioned and the plant is expected to reach 
stable production in the first half of 2024.

The  Company  continued  to  progress  the  Niafarang 
Project through the year, most notably with the renewal 
of  the  Company’s  mining  licence  to  March  2027.  The 
renewal of the mining licence has resulted in increasing 
local  community  support  for  the  project,  including  by 
the  local  governor  and  local  media  representatives. 
Astron  will  continue  to  explore  relevant  opportunities 
to  advance  the  project,  including  through  possible 
farm-out  arrangements,  Public  Private  Partnerships  or 
other mutually beneficial structures.

The Donald Project
The Donald Rare Earth & Mineral Sands Project (Donald Project) is a globally 
significant  rare  earth  and  mineral  sands  project  located  in  the  Wimmera 
region of Victoria, approximately 300km north-west of Melbourne. The project 
comprises  the  granted  mining  licence  MIN5532  (the  site  of  the  first  phase 
development of the project), retention licence RL2002 (which is the site of  the 
second phase of project development), and retention licence RL2003 covering 
a total project area of almost 43,000 hectares. 
LOCATION 
The area is mainly cleared land, used for cropping and grazing, and is located 
close to supporting infrastructure. The Project encompasses two deposits: Donald 
(RL2002, which contains MIN5532) and Jackson (RL2003). 
Development will follow a two-phase process. Phase 1 activities are located on MIN5532, and Phase 2 will occur on 
RL2002. The Jackson deposit, which is contained within RL2003, is available for subsequent development.
The Donald Project comprises a total Mineral Resource of 2.6 billion tonnes of ore at 4.6% HM content and includes 
the world’s largest zircon resource with over 22Mt of in-situ zircon content. The rare earth bearing monazite content 
alone, which equates to approximately 1.6Mt of total rare earth oxide (TREO) equivalents, ranks the Project as the 
third largest of its kind outside of China. Detailed delineation of the xenotime content of the total deposit is expected 
to increase the Project’s total rare earth element content.

Resource and Reserve updates
MIN5532 Reserve update
See pages 34-41 for detailed tables of current reserves 
and resources.
MIN5532 Drilling Program 
& Resource update
An  updated  Mineral  Resource  estimate  for  MIN5532 
was released in December 2022. It was based on a 245 
Reverse-Circulation Air Core (RCAC) drillhole program 
completed 
in  March  2022.  The  updated  Mineral 
Resource estimate for MIN5532 is 525 Mt at 4.0% total 
heavy minerals (HM) containing in-situ HM content of 
21Mt including approximately 3.4Mt of zircon, and over 
500kt of rare earth bearing monazite and xenotime.
The  2022  drill  program  covered  97%  of  MIN5532  to 
expand  the  estimated  valuable  heavy  minerals  (VHM) 
content within the known mineralisation of MIN5532, in 
areas not previously subject to VHM analysis. Analysis 
for xenotime and the 20 to 38 micron (μm) fine-grained 
mineralisation  fraction,  known  to  contain  rare  earth 
minerals  and  zircon,  was  also  targeted.  The  updated 
MIN5532  resource  defines  HM  grain  size  between 
20μm and 250μm as a resource. For the remainder of 
the Donald deposit, the HM in-size range remains 38μm 
to 90μm.
The  drilling  program  targeted  areas  outside  of  the 
previously defined ore body. In addition to the broader 
in-size particle range, this resulted in a 66% increase in 
the total Mineral Resource. 
Following  the  updated  Mineral  Resource  estimate  for 
MIN5532,  and  in  conjunction  with  work  associated 
with  the  DFS,  an  updated  Ore  Reserve  estimate  for 
MIN5532 was released on 31 March 2023. The total Ore 
Reserves of MIN5532 increased by 59.3% to 309Mt. Total 
in-situ  heavy  mineral  (HM)  reserves  increased  by  32% 
to  13.6Mt,  including  increases  in-situ  valuable  mineral 
reserves of zircon by 15% to 2.2Mt,  monazite by 25% to 
245kt and a maiden in-situ xenotime reserve of 90kt.
RL2002 Reserve update
A  Pre-Feasibility  Study  (PFS)  for  the  development  of 
the Donald Phase 2 project was carried out during the 
year.  The  Phase  2  development  is  located  on  RL2002 
with  operations  proposed  to  the  south  and  the  north 
of MIN5532. In conjunction with the release of Phase 2 
PFS results, an updated Ore Reserve estimate for RL2002 
was  released  in  June  2023.   The  updated  RL2002  Ore 
Reserve increased by 27% to 516Mt at 4.6% HM grade, 
including a 27% increase in zircon reserves to 4.4Mt and 
an increase of 29% in monazite reserves to 0.4Mt
Following the updated Ore Reserve estimates for both 
MIN5532  and  RL2002,  the  combined  Ore  Reserve 
estimate for the Donald Project now stands at 825Mt at 
4.5% HM grade with 36.9Mt of heavy minerals, including 
6.6Mt of zircon and 720kt of monazite and xenotime.

Mining Operations
Over  the  41.5  year  Phase  1  project 
life,  mining 
operations will produce, on average, 7.5Mtpa of ore for 
processing  to  produce,  on  average,  229ktpa  of  heavy 
mineral  concentrate  (HMC)  and  7.2ktpa  of  rare  earth 
concentrate (REEC).
The key features of Phase 1 operations, to be carried 
out on MIN5532, are:
•  Conventional truck and shovel open-pit mining
activities to be carried out by an independent
contractor;
•  Ore will be pumped to a Wet Concentrator
Plant (WCP) to Produce a mixed Heavy Mineral
Concentrate (HMC); and
•  The mixed HMC will be fed to the concentrate
upgrade plant (CUP) where it will be separated by
flotation into final products of a rare earth element
concentrate (REEC) and an HMC containing zircon
and titanium dioxide minerals.
Phase 1 Operations Diagram
24
Astron 2023 Annual ReportPhase  2  operations  will  be  carried  out  on  RL2002  to 
the  north  and  south  of  MIN5532.  Phase  2  has  been 
separated into two sub-phases:
Phase  1  has  an  average  strip  ratio  of  1.6:1,  which 
increases  to  2.2:1  for  the  total  Phase  1  and  Phase  2 
projects.
•  Phase 2a operations involve a duplication of
Phase 1 operations approximately doubling ore
throughput and production of HMC and REEC.
Technical processing risks have been mitigated 
through pilot plant scale testing of the HMC and REEC 
processing flow sheets including: 
•  Phase 2b involves the construction of a mineral
separation plant (MSP) to process HMC into final
downstream zircon and titania products. The MSP,
with a throughput of 15Mtpa, will be capable of
processing the HMC streams from both the Phase
1 and Phase 2a operations.

“Critical minerals are metallic or non-metallic 
materials that are essential to our modern 
technologies, economies and national security, and 
whose supply chains are vulnerable to disruption.”
Why is it important?
Critical  minerals,  including  rare  earth  elements,  are 
used  to  manufacture  key  technologies.  This  includes 
the technologies that will help us transition to net zero 
emissions, such as:
• electric vehicles (EVs)
• batteries
• permanent magnets
• wind turbines
• solar photovoltaics (PV)
• hydrogen electrolysers
• energy-efficient technologies like LEDs.
Critical  minerals,  and  the  technologies  they  enable, 
have  important  applications  across  a  range  of  sectors 
such as:
• defence
• space
• energy
• transport
• agri-tech
• medicine
• computing
• telecommunications.
Global  supply  chains  operate  most  efficiently  when 
they are diverse and transparent. Supply chains that are 
highly concentrated are fragile, volatile and unreliable. 
In  these  cases,  markets  cannot  adequately  price  and 
manage  risks,  meaning  businesses  cannot  compete 
on  a  level  playing  field.  As  a  result,  there  is  a  role  for 
governments  to  work  with  the  private  sector  to  build 
diverse, resilient and sustainable critical minerals supply 
chains.
Net zero 2050
Net  zero  is  cutting  greenhouse  gas  emissions  to  as 
close to zero as possible, with any remaining emissions 
to be re-absorbed from the atmosphere by oceans and 
forests. According to the United Nations, the transition  
to net-zero is one of the greatest challenges human-kind 
has  ever  faced.  It  requires  a  complete  transformation 
of  how  we  produce,  consume  and  move  around  and 
will involve the replacement of hydrocarbon fuels with 
electrical  energy  from  renewables,  such  as  wind  and 
solar. A new suite of materials is needed is propel this 
transition. 
Astron  recognises  the  Donald  Project’s  potential  to 
advance Australia’s commitment to the development of 
sustainable and inclusive mining practices and sourcing 
of critical minerals, as part of its role as a signatory of 
the Sustainable Critical Minerals Alliance.

MARKETING & PRODUCTS
Rare earths market
Donald’s  REEC,  which  contains  the  rare  earth  bearing 
minerals  monazite  and  xenotime,  will  be  sold  to 
customers for downstream processing. Total rare earth 
oxide (TREO) demand is forecast to increase from 2022 
to 2035 at a CAGR of 6.0%, driven by the expansion of 
the  permanent  magnet  sector,  in  line  with  increasing 
demand for electric vehicles, wind turbines and electric 
motor applications.
China  has  historically  dominated  rare  earth  supply, 
accounting for 70%1  of world mine production in 2022. 
Major rare earth element applications
Increasing  demand  for  rare  earths  has 
improved 
the  economics  of  prospective  mining  projects,  with 
numerous  projects  outside  of  China  aiming  to  reach 
production  by  2033.  Of  these,  14  rare  earth  projects 
(including  Donald)  have  completed  feasibility  studies 
and only three projects have commenced production. 
Supply  from  developing  projects  is  not  expected  to 
come  online  in  time  to  meet  forecast  demand,  with 
shortages for certain rare earth elements expected from 
as  early  as  next  year.  The  Donald  Project’s  advanced 
timetable allows it to come online at an opportune time 
to benefit from these favourable market dynamics.

Donald project REEC attributes
important  characteristic  of  the  Donald  REEC, 
An 
which  differentiates  the  project  from  many  of  the 
western  world  rare  earth  producers,  is  its  high  heavy 
rare  earth  element  content  which  is  contained  in  the 
mineral xenotime. Xenotime is a source of the valuable 
heavy  rare  earths  Dysprosium  and Terbium  which  are 
particularly important in the production of powerful, 
heat tolerant magnets with special applications in electric 
vehicles. The global heavy rare earth market is dominated 
by  Myanmar  and  south  China  producers.  Conversely, 
monazite contains the lighter rare earths neodymium and 
praseodymium which have broader applications and are 
less valuable. The Donald Deposit has a high xenotime to 
monazite ratio of greater than 0.3:1.

Astron 2023 Annual ReportMineral Sands Market
Zircon Attributes
Today,  there  are  3.5Mt  of  mineral  sands-based  heavy 
mineral concentrates products being supplied to China, 
however, there is at least 7Mt of HMC separation capacity 
within  China.  This  creates  a  favourable  dynamic  for 
Astron to supply Chinese MSPs with Donald HMC. The 
HMC market is highly correlated with its end products, 
which are mainly zircon and titanium dioxide minerals.
Metallurgical  test  work  undertaken  on  Donald  HMC 
indicates a high proportion of premium grade zircon can 
be commercially recovered. Furthermore, the test work 
shows  Donald  zircon  has  high  whiteness  levels  and 
low levels of impurities in comparison with competing 
zircon  products.  This  provides  a  distinct  competitive 
advantage for supply to the ceramics market.
HMC product
Titania Attributes 
Titanium feedstocks are primarily used in the production 
of TiO2 pigment, which has a wide range of applications 
including  paint,  plastics,  and  coatings.  To  meet  the 
requirements  of  the  pigment  production  process, 
relatively low grade TiO2 minerals can be processed into 
intermediate  products  with  higher  TiO2  content,  such 
as titanium slag. Test work indicates that Donald Project 
titania  is  a  desirable  feedstock  for  producing  titanium 
slag a for the Chloride TiO2 pigment process, known as 
chloride slag. As a 66% TiO2 product, with low calcium 
content, Donald titania has a particular application as a 
“sweetener” (or higher titanium dioxide content) feed to 
existing chloride slag feeds.
Titania Market
Astron’s  titanium  dioxide  product  can  be  regarded 
as  a  hybrid TiO2  product  (referred  to  as  titania)  which 
contains  a  spectrum  of  TiO2  minerals  ranging  from 
ilmenite  to  rutile.  With  an  average  TiO2  grade  of  66%, 
it  is  particularly  well-suited  to  producing  chloride  slag 
feedstock for the chloride pigment production process.  
The  chloride  slag  based  pigment  production  process 
is the fastest growing segment of the pigment market. 
Most  of  the  growth  is  expected  to  come  from  China, 
where  capacity  is  forecast  to  grow  at  10%pa  with  an 
estimated 913,000 tonnes of capacity installed by 2030. 
China  is  rapidly  adopting  chloride  pigment  process 
technologies to provide an onshore source of chloride 
pigment for high-end applications.
As  forecast  by  mineral  sands  and  pigment  specialists, 
TZ Minerals International (TZMI) Pty Ltd, global chloride 
slag  demand  will  increase  by  an  8.6%  CAGR  to  2030, 
influencing demand for high-quality ilmenite feedstock 
to slag production.
Extensive  metallurgical 
test  work  undertaken  by 
Astron,  with  the  support  of  Mineral  Technologies,  has 
determined  the  specifications  for  the  Donald  HMC 
product.  Following  removal  of  the  rare  earth  content, 
the  Project  will  target  a  95%  heavy  mineral  grade, 
resulting  in  a  higher  proportion  of  valuable  minerals 
and lower waste than is typically found in heavy mineral 
concentrates.  In  addition,  given  its  favourable  zircon 
assemblage,  the  Donald  HMC  is  expected  to  contain 
higher  zirconium  dioxide  (ZrO2)  concentration  than 
competitor HMCs, increasing its value to mineral sands 
processors.
The  Company  has  conducted  separation  testing  of 
Donald  HMC  into  final  products  at  laboratory  and 
pilot  plant  scales.  Zircon  recovery  was  85%,  with  71% 
recovered  as  premium  zircon  and  14%  as  secondary 
zircon.  Recovery  of  combined  titania  product  was 
86%. The test work demonstrates the ability to achieve 
commercial recoveries of final products from Donald’s 
HMC product.
Zircon market
Declining  zircon  supplies  globally  have  created 
economic  tailwinds  for  producers.  The  current  global 
zircon  consumption  is  approximately  1.2Mtpa.  This 
is  forecast  to  grow  to  1.6Mtpa  by  2030,  an  annual 
compound growth rate of 2.8%. Ceramics is the major 
end-use  for  zircon,  accounting  for  approximately 
half  of  zircon  global  demand.  Demand  is  driven  by 
urbanisation and consumption trends, notably in China, 
which accounts for approximately half of zircon global 
demand.
In  the  short  term,  economic  conditions  in  China  are  
reducing demand. However, in the medium term, supply 
forecasts  indicate  that  production  will  be  insufficient 
to  meet  current  levels  of  demand.  Historically,  zircon 
supply  has  been  concentrated  between  a  small 
number  of  key  players  accounting  for  about  60%  of 
global  supply.  However,  due  to  maturation  and/or 
grade decline, these suppliers only accounted for 45% 
of  global  zircon  production  in  2021.  The  increasing 
scarcity  is  projected  to  create  supply  shortages,  and 
the Donald Project represents a timely source that will 
benefit from increasing prices.

within  a  currently  expired,  but  subject  to  renewal, 
exploration 
licence  covering  a  highly  mineralised 
coastal  zone  of  almost  400km2  that  stretches  75 
kilometres north-south along the Casamance coast. 
The  planned  mining  approach  involves  conventional 
dry  mining  with  nearby  concentrating  and  the  sale  of 
concentrate  to  a  toll  processor  or  to  Astron’s  Chinese 
facilities in Yingkou. 
The Niafarang Mining Licence was renewed in February 
2023.  Continued  engagement  with  regulators  and 
community  groups  in  Senegal  provides  the  basis  for 
the  future  progression  of  the  Niafarang  mineral  sands 
project to a construction and production stage.

ESG & Community engagement
Stakeholder Engagement
Economic impact study
Astron  recognises  the  importance  of  its  social  licence 
to  operate  and  is  committed  to  working  with  the 
communities  in  which  its  activities  are  located  to 
maximise benefits to all stakeholders.
Australia
During  the  year,  Donald  Mineral  Sands  staff  have 
continued to engage with State and Federal members 
of  parliament,  local  community  groups  and  Shire 
Councils to provide project updates and discuss issues 
of concern including labour, housing and opportunities 
for local businesses.
Community Sponsorships
Astron completed another round of the DMS Community 
sponsorship  program  with  funding  provided  to  four 
community projects and events. The Company was able 
to  sponsor  the  Donald  Golf  and  Bowls  Club  senior  and 
junior golf tournaments, contributed to a new printer for 
the  monthly  Minyip  Lions  Club  community  newsletter, 
supported the Murtoa show and are sponsoring the live 
music and film presentation at Murtoa’s Big Weekend. 
In November 2022, Deloitte’s Access Economics team 
undertook a detailed economic impact analysis (EIA) of 
Phase 1 operations on MIN5532. The study focused on 
the impact of employment, economic flow-on benefits 
and improved social infrastructure to the local project 
area and the wider Victoria region. Economic impacts are 
long-lasting over the 40 year life of Phase 1 operations.
Key economic findings for the local project area 
include:
•  Increased economic activity by a present value of
$2.2 billion
•  Average annual economic boost in output of $205
million
•  Creation of 150 full time equivalent (FTE) direct jobs
(including contractors)

Test Pit rehab update
Over 1,000 tonnes of ore was extracted from a test pit during metallurgical work for the DFS. The disturbed land was 
rehabilitated in 2018 and has since been used for agriculture operations. Multiple successful harvests, including this 
year’s harvest of barley crop, continue to demonstrate the effectiveness of Astron’s rehab process in action.

Ore Reserves & Mineral Resources Statement
The following provides an overview of the JORC 2012 compliant Ore Reserves and 
Mineral Resources for the Donald Rare Earth and Mineral Sands Project. 
The Ore Reserves and Mineral Resources Statement is based on, and fairly presents, 
information  and  supporting  documentation  prepared  by  a  competent  person  and 
the Ore Reserves and Mineral Resources as a whole have been approved by a named 
competent person, as seen in the Competent Persons Statement on page 40.
Ore Reserves
Astron announced updated Ore Reserves totalling 309Mt at 4.4% HM for MIN5532 on 31 March 2023 (Table 1). The Ore Reserve 
estimate is based on the  MIN5532 Mineral Resource estimate, announced to the ASX on 1 December 2022 that used heavy 
liquid separation analysis to estimate tonnes, HM, slimes and oversize plus valuable heavy mineral data.. Measured and Indicated 
Mineral Resources were converted to Proved and Probable Ore Reserves respectively, subject to mine design, modifying factors 
and underlying economic evaluation.
Astron announced updated RL2002 Ore Reserves totalling 516Mt at 4.6% HM on 27 June 2023 (Table 1). The Ore Reserve 
estimate is based on the RL2002 Mineral Resource estimate, announced to the ASX on 7 April 2016. Measured and Indicated 
Mineral Resources were converted to Proved and Probable Ore Reserves respectively, subject to mine design, modifying factors 
and underlying economic evaluation.
Based on the announced updates to the Ore Reserves for MIN5532 and RL2002, total Ore Reserves of the Donald Deposit 
increased by 223Mt (37%). Total in-situ zircon reserves increased by 22.6% to 6.7Mt and in-situ monazite reserves increased by 
32.0% to 648.2kt.
The Ore Reserve Statement is reported in accordance with the guidelines of the Australasian Code for Reporting of 
Exploration Results, Mineral Resources and Ore Reserves, 2012 Edition and ASX Listing Rules (JORC Code (2012). The 
Statement includes a revised Ore Reserves estimate of the Donald project that complies with the requirements of the 
JORC Code (2012).

Notes to Tables 1 & 2:
1.
 The ore tonnes have been rounded to the nearest 1Mt and grades have been rounded to one decimal place except for xenotime which is rounded 
to two decimal places.
2. The Ore Reserve is based on Indicated and Measured Mineral Resource contained within mine designs above an economic cut-off.
3. A break-even cut-off has been applied defining any material with product values greater than processing cost as Ore.
4. Mining recovery and dilution have been applied to the figures above.
5.
 The updated RL2002 Ore Reserve does not include an announced figure on xenotime due to historical samples used in the Ore Reserve calcu-
lation not being analysed for xenotime. Further drilling work consisting of a maximum of 958 drillholes may be undertaken to further define the 
Ore Reserve and delineate the xenotime content. Metallurgical test work confirms the existence of xenotime to be relatively consistent across the 
mineral deposit, which represents upside to the announced combined rare earth mineral figures. Thus, the xenotime content of the entire Donald 
Deposit has not been stated.
6. The rutile grades are a combination of rutile and anatase minerals.
7.
The Ore Reserve estimates have been compiled in accordance with the guidelines defined in the 2012 JORC Code
The Ore Reserve estimate was prepared by AMC Consultants Pty Ltd, an experienced and prominent mining engineering   
with  appropriate  mineral  sands  experience  in  accordance  with  the  JORC  Code  (2012  Edition).  The  Ore  Reserve  is 
estimated using all available geological and relevant drill hole and assay data, including mineralogical sampling and 
test work on mineral recoveries and final product qualities.
The Company is not aware of any new information or data that materially affects the information included in the Ore 
Reserve  estimate  and  confirms  that  all  material  assumptions  and  technical  parameters  underpinning  the  estimate 
continue to apply and have not materially changed. 
35
Ore Reserves & Mineral Resources Statement
Mineral Resources
Mineral  Resources  only  used  heavy  liquid  separation  analysis  to  estimate  tonnes,  HM,  slimes  and  oversize  for  the 
Donald Project using a 1% HM cut-off grade. Resources were last estimated for MIN5532 on 1 December 2022 with 
RL2002 and RL2003 on 7 April 2016. These Mineral Resources represent resource estimates with and without valuable 
heavy  mineral  (VHM)  data  to  provide  a  guide  to  the  total  potential  tonnes  and  HM%  for  the  Donald  and  Jackson 
deposits. Resources without VHM data were not used in the Ore Reserve Estimation by AMC. The Mineral Resources 
for the Donald and Jackson deposits based on 1% HM cut-off grade is shown in Table 2.
Based  on  the  updated  Mineral  Resource  for  MIN5532  as  outlined  above,  total  Mineral  Resources  reported  above  a  
1% total HM cut-off increased by 69Mt (1.2%), highlighted by a 3.1% increase in inferred resources to 737Mt.

The  Mineral  Resources  for  the  Donald  deposit  based  on  1%  HM  cut-off  grade  and  valuable  heavy  mineral  data  are 
shown in Table 5. The generation of the Ore Reserve estimates outlined Table 1 for the proposed Phase 1 and 2 of the 
Donald Project is based on the Measured and Indicated resources outlines in Table 5 below.
Based  on  the  updated  Mineral  Resource  estimate  for  MIN5532  announced  on  1  December  2022,  total  Mineral 
Resources where VHM data is available reported above 1% total HM cut-off increased by 207Mt (8.5%) highlighted by 
increases in Measured resources of 131Mt and Indicated resources of 61Mt. Contained rare earth minerals increased by 
approximately 200kt as a result of an increase in monazite and the addition of a 135kt maiden resource.

6.
The cut-off grade is 1% HM.
 The figures are rounded to the nearest: 1Mt for tonnes, one decimal for HM, monazite, whole numbers for slimes, oversize, zircon, rutile + anatase, 
ilmenite and leucoxene and two decimals for xenotime.
Zircon, ilmenite, rutile+anatase, leucoxene, monazite and xenotime percentages are reported as a percentage of HM.
 Rutile + anatase, leucoxene and monazite resource has been estimated using fewer samples than the other valuable heavy minerals outside 
MIN5532.  The accuracy and confidence in their estimate is therefore lower. 
The Australian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, 2012 Edition, sets out 
minimum standards, recommendations and guidelines for public reporting in Australia of Exploration Results, Mineral 
Resources and Ore Reserves authored by the Joint Ore Reserves Committee of The Australian Institute of Mining and 
Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia.

Astron Corporation Limited 
Company Number: 1687414 
Directors' Report 
30 June 2023 
OPERATIONAL AND FINANCIAL REVIEW 
Business Highlights 
•  Significant  progress was made at the Donald  Rare Earth and Mineral Sands Project with  the completion  of the  Definitive 
Feasibility Study (DFS) for MIN5532 (the site of Phase 1 operations) in April 2023 and the Pre-Feasibility Study (PFS) for 
RL2022  (the  site  of  Phase  2  operations)  in  June  2023.  In  conjunction  with  the  completion  of  the  DFS  and  PFS,  updated 
Mineral Resource and Ore Reserve estimates were completed for MIN5532 along with an updated Ore Reserve estimate for 
RL2002. The Project also made substantial progress towards finalisation of the Victorian Work Plan (which is expected to be 
submitted to the regulatory authorities in October 2023) and critical off-site infrastructure including overhead powerline, road 
and water upgrades and accommodation village.   
•  China Government-based COVID-19 restrictions, along with the variability and scarcity of stable sources of raw materials, 
significantly hampered the utilisation of the Yingkou Mineral Separation Plant. The plant was shutdown in Mid-March whilst 
negotiations for raw materials supply continued. Following some upgrades to the plant completed during the shutdown, it is 
anticipated that the plant will be restarted in October 2023 following finalisation of raw material supply contracts. 
• 
The  Company’s  Mining  Licence  for  the  Niafarang  project  was  renewed  in  February  2023.  Continued  engagement  with 
regulators and community groups in Senegal as a basis for the future progression of the Niafarang mineral sands project to 
a construction and production stage. 
Financial results – key features 
The main features of the 2023 financial results are provided below. Segmental results are provided in Note 4 to these financial 
statements, which provide information on the financial performance for the main business entities and activities of the Group. 
Revenue 
Sales revenue decreased by 23.9% to $14,458,725 (2022: $18,999,516) primarily as a result of shut down of the plant in Mid-
March 2023 due to the variability and scarcity of stable sources of raw materials. Further, Chinese Government COVID-19 related 
lockdowns adversely impacted the operations during the third and fourth quarters of 2022. 
Expenses 
The  Company’s  general  and  administrative  expenses  decreased  from  2022 to  2023  from  $7,642,970  to  $6,076,128  reflecting 
decreased product research and development expenses in China, decreases in legal fees relating to the proposed demerger of 
the China operations and an increase in capitalisation of employee wages relating to the Donald Project. 
Net loss 
The  Company  recorded  a  consolidated  net  loss  before  tax  of  $6,039,121  (2022:  $7,018,342),  a  reduction  of  the  net  loss  of 
$979,221 or 14.0%. The decrease in gross margin experienced at the Yingkou operations during the year (as outlined above) was 
offset by an increase in research and development tax incentive income of $1,543,575, a decrease in general and administrative 
costs of $1,566,842 and reduction in non-cash share-based payments of $334,166. 
Operating cash flow 
Cash outflows from operations were $1,647,745 (2022: Operating cash inflows of $394,168) reflecting an increase in the loss 
before tax and lower non-cash impairment of capital works in progress offset by changes to working capital balances during the 
year, with trade and other receivables decreasing by $7,249,373 offset by a decrease in trade and other payables of $5,213,606. 
Net assets 
The Group’s net assets as at 30 June 2023 increased to $90,496,303 (2022: $85,503,285) as a result of capital raising activities 
during the year of $12,683,340 (net of costs) offset by the Company’s total comprehensive loss for the year of $8,115,006. 
OPERATIONS REVIEW 
Donald 
The Donald Project is a long-life mining asset, comprising a world class reserve of rare earths, zircon and titanium minerals with 
the potential to generate significant value through low-risk conventional mining and heavy mineral processing operations.   
The Phase 1 Donald Project Definitive Feasibility Study (DFS), which was released in April 2023, confirmed Donald as a Tier 1, 
globally significant critical minerals project. The DFS is the culmination of many years of metallurgical testing, detailed design and 
engineering, community engagement and regulatory approvals.

Astron Corporation Limited 
Company Number: 1687414 
Directors' Report 
30 June 2023 
Economically, the Phase 1 project is expected to deliver an NPV8 of $852 million on an initial capital investment of $364 million. 
Average annual free cash flow is estimated at $110 million per annum for the first five years, and $103 million per annum over the 
remainder of the 41.5-year mine life. For a project that generates impressive long-term value it has a relatively short payback 
period of under four years to be followed by many decades of mining operations to drive sustainable, long-term investment returns. 
The  Project’s  return  profile  is  attractive  and,  based  on  conservative  estimates,  delivers  a  post-tax  and  inflation-adjusted  real 
internal rate of return of 25.8%.   
Importantly, the Phase 1 project demonstrates a small portion of the full potential of the Donald Project. Once operational, Phase 
1 cash-flows are anticipated to be applied to the equity requirements of the Phase 2 project  – for which the indicative project 
economics (at PFS level) show an incremental NPV of $1.4B, and an extension of the Phase 1 plus Phase 2 mine life from 41.5 
years to 58 years at twice the Phase 1 rate of production. The Donald Project will allow Astron to be a part of the global critical 
minerals landscape for many decades. 
Excitement continues to build around applications of rare earths as they are recognised as the building blocks for the evolution in 
electric  vehicles  and  renewable  energy.  A  3MW  wind  turbine  uses  close  to  40  kilograms  of  rare  earths  and,  if  the  world  is  to 
achieve its emissions targets, rare earth demand must increase significantly. 
The zircon component of Donald’s reserves, a high proportion of which has premium quality characteristics, will make a significant 
contribution to the ceramics markets where demand continues to grow due to the continuing global urbanisation trend. 
Rare  earths  and  zircon  supplies  are  both  expected  to  be  constrained  by  2026,  when  Donald  Phase  1  is  expected  to  be  in 
production. Donald’s planned scale and development timing are both crucial not only for supporting energy transition, but also for 
meeting the supply requirements for the zircon industry, for which a large proportion of current supply is expected to deplete within 
the next 3 to 5 years.   
While  Astron  commenced  the  process  of  engagement  with  potential  product  off-take  partners  in  the  early  stages  of  project 
evaluation, the completion of the DFS has facilitated the start of detailed discussions with several parties to secure firm off-take 
agreements prior to the start of construction.   
Prior to the start of construction, Astron must also agree the terms of a work plan with the Victorian Government. The work plan 
describes  the  nature  and  scale  of  the  proposed  mining  activities,  identifies  and  assesses  all  risks  the  works  may  pose  to  the 
environment,  details  the  nature  of  community  engagement,  and  includes  a  risk  management  plan  to  eliminate  or  minimise 
identified risks and monitor performance. The Company is very advanced towards finalisation of the work plan. 
Astron raised close to $13 million in equity during the year. $5.9 million was raised from share offers with significant support from 
Astron directors and executives. The high related party ownership of those closest to the project indicates our conviction in the 
underlying value of the Project. We are also pleased to announce support from Mr Tan Ruiqing, Former Vice Chairman and one 
of the founders of Lomon Billions Group, who invested $7 million in a placement for Astron shares. We welcome the support from 
a sophisticated investor with deep experience in the titanium dioxide and zirconium chemical markets. 
Astron aims to fund the Phase 1 execution investment with a split of 60% debt and 40% equity. ICA Partners have been appointed 
as our debt advisor to secure appropriate debt financing to support construction. ICA Partners are a globally recognised resource 
specialist firm, experienced in critical mineral projects’ financing, notably Iluka’s $1.25 billion Eneabba Rare Earths refinery. Market 
soundings of potential financiers has been completed with strong interest from domestic and foreign institutions. It is expected 
that financiers will confirm their interest in the debt financing process during Q4 2023 and further assessment and negotiation to 
be completed during Q1 2024. 
The Pre-Feasibility Study (PFS) for Phase 2 of the Donald Project, also completed during the year, confirmed the project’s place 
as  a  Tier-1  rare  earth  and  mineral  sands  project  of  long-term  global  significance.    Construction  for  Phase  2  of  the  project  is 
planned to commence in 2029 with first production towards the end of 2030. Furthermore, the utilisation of just over 40% of the 
Donald Project Mineral Resource over the combined Phase 1 and Phase 2 projects’ 58-year life is a clear indication of the potential 
for further value creation by way of scale expansion as well as the production of a wide range of materials that are essential to life 
in the 21st century. 
During the year, the Company announced updates to the Mineral Resource and Ore Reserve for MIN5532 (the site of Phase 1 
operations)  and  the  Ore  Reserve  for  RL2002.  Completed  detailed  analysis  of  the  2022  drilling  program  has  increased  both 
Reserves  and  Resources  on  MIN5532.  Much  of  this  increase  is  explained  by  widening  the  in-size  range  and  drilling  samples 
extending the previously defined ore body. A significant increase in rare earth content was recorded as the xenotime content was 
added  to  Valuable  Heavy  Mineral  (VHM)  analysis.  Expanding  our  reserves  is  a  significant  development,  as  it  strengthens  the 
underlying value of the overall project. Following the updated Ore Reserve estimates announced for both MIN5532 and RL2002, 
total Donald Project Ore Reserves have increased by 37% to 825Mt since 30 June 2022.

Directors' Report 
30 June 2023 
China operations 
FY2023 was a challenging year for Astron’s Chinese operations. Continuing COVID-19 restrictions, including serious lockdowns 
experienced across major cities in the first half of the financial year, and the on-going industry re-opening difficulties in the latter 
half of the financial year contributed partly to the lower year on year revenue, which dropped from $19.0m in FY2022 to $14.5m 
in 2023. In addition, supply chain difficulties, and difficulties in sourcing concentrate product meant that a larger proportion of the 
revenue this year was derived from relatively low margin trading activities, rather than from processing plant operations.   
A business review of the Chinese operations, which considered among other things the difficulties in securing long-term feedstock, 
led to a change in operating strategy to open up the plant to a wider range of concentrate feedstocks (including in preparation for 
Donald HMC). This resulted in the installation of new separation spirals in the mineral separation plant and has made a positive 
contribution  towards  securing  a  number  of  long-term  feedstock  supply  arrangements.  The  new  process  flowsheet  is  being 
commissioned and the plant is expected to reach stable production in the first half of 2024. 
Senegal 
The Company continued to progress the Niafarang Project through the year, most notably with the renewal of the Company’s 
mining licence to March 2027. The renewal of the mining licence has resulted in increased local community support for the project, 
including from the local governor and local media representatives. Astron will continue to explore relevant opportunities to advance 
the project, including through possible farm-out arrangements, Public Private Partnerships or other mutually beneficial structures. 
BUSINESS RISKS 
Supply risk 
The Company is dependent on renewing its existing supply contracts for rutile and zircon middlings to be processed through its 
plants in China. The Company is currently in advanced discussions with additional feedstock suppliers. 
Funding risk 
The Donald Project is expected to require a significant capital investment. The Company may seek to raise funds through equity 
or debt financing or other means. The terms of such financing cannot be determined at this point and may result in delays in 
execution timelines for the project. 
Project execution risk 
Project timeframes, capital expenditure, equipment availability, ability to access key personnel or a combination of these and other 
factors have been captured as potential risks in the risk matrix. Where foreseeable delays which may cause either a delay in the 
completion of the Donald Project or an overrun in terms of capital expenditure or operational costs, it will be allocated for in the 
functional revisions and mitigated at that point. 
Geopolitical risk 
The Company intends to export its products from the Donald Project to various markets. There is a risk that geopolitical risks 
could adversely impact the proposed sales including intended sales to the Company’s subsidiary operations in China. 
Commercial and contract risk 
Potential future earnings, profitability and growth are likely to the Company’s ability to successfully implement its business plans. 
The Company’s ability to do so depends on a number of different factors, including matters which may be beyond the control of 
the Company. 
Commodity price risk 
The Company’s future revenues are expected to be derived mainly from mineral sands products, rare earth concentrate sales and 
royalties gained from potential joint ventures or other arrangements. Consequently, the Company’s potential future earnings will 
likely  be  closely  related  to  the  price  of  such  minerals  which  may  fluctuate  and  exchange  rate  risks  for  products  sold  when 
denominated in currencies other than the Australian dollar. 
Exchange rate risk 
The  revenue,  earnings,  assets  and  liabilities  of  the  Group  may  be  exposed  adversely  to  exchange  rate  fluctuations.  The 
Company’s revenue may be denominated in a foreign currency, and as a result, fluctuations in exchange rates could result in 
unanticipated and material fluctuations in the financial results of the Group.

Directors' Report 
30 June 2023 
REMUNERATION REPORT 
Policy for determining the nature and amount of Key Management Personnel (KMP) remuneration 
The remuneration policy of the Group has been designed to align director and executive objectives with shareholder and business 
objectives by providing a fixed remuneration component and offering potential long-term incentives based on key performance 
areas  affecting  the  Group's  financial  results.  The  board  of  Astron  Corporation  Limited  believes  the  remuneration  policy  to  be 
appropriate and effective in its ability to attract and retain the best executives and directors to run and manage the Group, as well 
as create goal congruence between directors, executives and shareholders. 
The Board's policy for determining the nature and amount or remuneration for the board members and senior executives of the 
Group is as follows: 
• 
The remuneration policy for executive directors and other KMP was developed by the Nomination & Remuneration committee 
and approved by the Board after seeking professional advice from an independent external consultant. 
•  All executives receive a market-related base salary (which is based on factors such as length of service and experience), 
other statutory benefits and potential performance incentives. 
• 
The Nomination & Remuneration committee reviews executive packages annually by reference to the Group’s performance, 
executive performance and comparable information from industry sectors. 
The  performance  of  executives  is  measured  against  criteria  agreed  with  each  executive  and  is  based  predominantly  on  the 
forecast growth of the Group’s profits and shareholders’ value. All bonuses and incentives are linked to the performance of the 
individual  and  are  discretionary.  The  objective  is  designed  to  attract  the  highest  calibre  of  executives  and  reward  them  for 
performance that results in long term growth in shareholder wealth. 
At the discretion of the Committee from time to time shares are issued to executives to reflect their achievements. The Board has 
approved the Employee Share Option Plan (ESOP) and, subsequent to shareholder approval, options were issued to directors 
and other employees and consultants. 
Where applicable executive directors and executives receive a superannuation guarantee contribution required by the government, 
which was 10.5% during the year ended 30 June 2023 increasing to 11.0% in the year ending 30 June 2024, and do not receive 
any other retirement benefits. 
Some individuals, however, have chosen to sacrifice part of their salary to increase payments towards superannuation. 
If shares are given to directors and/or executives, these shares are issued at the market price of those shares. 
The board policy is to remunerate non-executive directors at market rates for time, commitment and responsibilities. The Board 
determines payments to the non-executive directors and reviews their remuneration annually, based on market practice, duties 
and accountability. Independent external advice is sought when required. The maximum aggregate amount of fees that can be 
paid to non-executive directors is subject to approval by shareholders at the Annual General Meeting. Fees for non-executive 
directors  are not  linked  to  the  performance  of  the  Group.  However,  to  align  director's  interests  with  shareholder  interests,  the 
directors are encouraged to hold shares in the Group. 
Performance based remuneration 
As part of each executive director and executive’s remuneration package there is a discretionary short term incentive element. 
This program intends to align the interests of directors and executives with those of the business and shareholders. 
In determining whether or not each executive director and executive's bonus is due, the Nomination & Remuneration committee 
bases the assessment on audited figures and independent reports where appropriate. 
The Nomination & Remuneration committee reserves the right to award bonuses where performance expectation has prima facie 
not been met but it is considered in the interests of the Group to continue to reward that individual. 
Discretionary bonuses of Nil (2022: Nil) were paid during the year. 
The Company is formalising a short-term incentive program that will be based on key performance indicators (KPIs) set at the 
beginning of the performance period and assessed at the end of the performance period. KPIs for each employee will be set with 
overall Group business, operating and financial objectives in mind and will be a combination of Group and individual performance 
measures. The terms of the short-term inventive program are currently being defined for review and approval by the Nomination 
& Remuneration committee.

The figures provided in ‘Share-based payment expenses’ were not provided in cash to the KMP during the financial period. These amounts 
are calculated in accordance with accounting standards and represent the amortisation of accounting fair values of performance rights that 
have been granted to KMP in this or prior financial years. The fair value of share options has been valued as at their date of grant and in 
accordance with the requirements of HKFRS 2 Share-Based Payments. The fair value of options is measured using a generally accepted 
valuation model. The fair values are then amortised over the entire vesting period of the equity instruments. Total remuneration shown in 
‘Total’ therefore includes a portion of the fair value of unvested equity compensation during the year. The amount included as remuneration 
is  not  related  to  or  indicative  of  the  benefit  (if  any)  that  individuals  may  ultimately  realise  should  these  equity  instruments  vest  and  be 
exercised. 
Paid or payable to management company. 
During the year ended 30 June 2023, Mr Tim Chase entered into an agreement with the Company to pay out a portion of the annual leave 
liability owing to him from past service. A total amount of $61,154 (before taxes and superannuation) was paid under the agreement which 
was included in the Group’s provision for annual leave at 30 June 2022. 
4.  Mr Greg Bell was appointed as the Chief Financial Officer of the Group on 3 October 2022 and, as such, become a member of KMP from 
this date. Mr Bell received 600,000 share options as part of his agreement to hold the position, with various vesting conditions as outlined 
in  Note  27  of  the  financial  statements.  These  share  options  have  been  valued  in  accordance  with  HKFRS  2  and  will  be  amortised  in 
accordance with the vesting conditions. 
5. 
During year ended 30 June 2021, non-executive director Dr. Mark Elliott was granted 800,000 options subject to shareholder approval. As 
at 30 June 2021, the Company estimated the grant date fair value with reference to the fair value as at the reporting date (i.e. 30 June 2021) 
to  be  $299,943  for  the  purpose  of  recognising  the  services  received  from  Dr.  Mark  Elliott.  Upon  receiving  shareholder  approval  on  30 
November 2021, the options were approved by the Board and the fair value of options granted to Dr. Mark Elliott was revalued to $229,308. 
As such, an adjustment to share-based payment expense of $70,635 was recognised in the profit or loss for the year ended 30 June 2022. 
Use of remuneration consultants 
The  Board  has  previously  employed  external  consultants  to  review  and  provide  recommendations  regarding  the  amount  and 
elements of executive remuneration, including short-term and long-term incentive plan design. No remuneration consultants were 
employed during the year. 
Termination payment 
No termination payments were paid during the year to KMP.

which were valued at $346,349 (2022: $645,094). The value of share options issued to KMP will be amortised in accordance with 
their vesting conditions to comply with HKFRS 2 Share based payments. 
Voting and comments at the Company’s 2022 Annual General Meeting 
The Company received 96.9% of “yes” votes on its remuneration report for the 2022 financial year. 
The Company did not receive any specific feedback at the AGM on its remuneration report. 
Service contracts 
Service contracts (or letters of engagement) have been entered into, or are in the process of being entered into, by the Group 
with  all  KMP  and  executives,  describing  the  components  and  amounts  of  remuneration  applicable  on  their  initial  appointment 
including  terms,  other  than  non-executives  who  have  long  established  understanding  of  arrangements  with  the  Group.  These 
contracts do not fix the amount of remuneration increases from year to year. Remuneration levels are reviewed generally each 
year by the Nomination & Remuneration Committee to align with changes in job responsibilities and market salary expectations. 
Other key management personnel have ongoing contracts with a notice period of three months for key management personnel. 
There are no non-standard termination clauses in any of these contracts. 
The Nomination & Remuneration Committee considers the appropriate remuneration requirements. In August 2012, the Group 
engaged external consultants to review the Group’s salary and incentive benchmarks. No consultants were engaged to review 
Group remunerations during the year ended 30 June 2023. 
END OF REMUNERATION REPORT 
INDEMNIFYING OFFICERS OR AUDITOR 
Insurance premiums paid for directors 
During the year, the Group paid a premium in respect of a contract indemnifying directors, secretaries and executive officers of 
the  Company  and  its  controlled  entities  against  a  liability  incurred  as  director,  secretary  or  executive  officer.  The  contract  of 
insurance prohibits disclosure of the nature of the cover. 
The Company has not otherwise, during or since the end of the financial year, except to the extent permitted by law, indemnified 
or agreed to indemnify an officer or auditor of the Company or any of its controlled entities against a liability incurred as such an 
officer or auditor. 
NON-AUDIT SERVICES 
During the financial year, the following fees for non-audit services were paid or payable to the auditor BDO Limited or its related 
practices: 
Other Services 
Taxation services 
Other assurance services

The directors are satisfied that the provision of non-audit services during the year by the auditor (or by another person or firm on 
behalf of the auditor) is compatible with the general standard of independence for auditors imposed by the Corporations Act 2001. 
The directors are satisfied that the provision of non-audit services by the auditor, as set out above, did not compromise the auditor 
independence requirements of the Hong Kong Institute of Certified Public Accountants (HKICPA) for the following reasons: 
• 
• 
all non-audit services have been reviewed by the Board to ensure that they do not impact the integrity and objectivity of the 
auditor; and 
none of the non-audit services undermine the general principles relating to auditor independence as set out by the HKICPA.

Company Number: 1687414 
Notes to the Consolidated Financial Statements 
For the year ended 30 June 2023 
1.  General Information 
The consolidated financial statements of Astron Corporation Limited for the year ended 30 June 2023 were authorised for 
issue in accordance with a resolution of the directors on 29 September 2023 and relate to the consolidated entity consisting 
of Astron Corporation Limited (“the Company”) and its subsidiaries (collectively “the Group”).   
The financial statements are presented in Australian dollars ($). 
Astron Corporation Limited is a for-profit company limited by shares incorporated in Hong Kong whose shares are publicly 
traded through CHESS Depository Interests on the Australian Securities Exchange (ASX). 
2.  Basis of preparation and significant accounting policies 
Basis of preparation 
The  financial  statements  have  been  prepared  in  accordance  with  Hong  Kong  Financial  Reporting  Standards  and 
Interpretations (hereinafter collectively referred to as the (“HKFRS”) issued by the Hong Kong Institute of Certified Public 
Accountants  (“HKICPA”)  and  the  provisions  of  the  Hong  Kong  Companies  Ordinance  which  concern  the  preparation  of 
financial statements. 
The financial statements have also been prepared on a historical cost basis, except for certain financial instruments which 
are measured at fair value as explained in the accounting policies set out below. 
Going concern basis 
As at 30 June 2023, the Group had a deficit of current assets over current liabilities of $11,615,438 (2022: $14,488,034), 
incurred a net loss after tax for the year of $7,730,992 (2022: net loss of $9,038,451) and recorded net cash outflows from 
operating activities of $1,647,745 (2022: net cash inflows of $394,168). The deficit of current assets over current liabilities, 
continued operating losses and net cash outflows from operating activities, are conditions, along with the matters set out 
below,  that  may  cast  significant  doubt  on  the  Group’s  ability  to  continue  as  a  going  concern.  The  consolidated  financial 
statements have been prepared on a going concern basis, which assumes the continuity of normal business activity and the 
realisation of assets and settlement of liabilities in the normal course of business. The directors are of the view that based 
on cash flow forecasts covering 18 months from the end of the reporting period and consideration of the plans and measures 
stated below, the business remains a going concern. 
The directors are confident it will have sufficient funds to meet its ongoing needs for at least the next 12 months from the 
date of this report based on the following: 
• 
• 
The Group has agreed contracts for stable supply of appropriate raw materials for the Group’s mineral separation plant 
in China. Agreement for a stable supply of raw materials is imperative to the sustainability and profitability of the mineral 
separation plant as not only will it ensure consistent production volumes (and, by extension, sales volumes), it will also 
allow the Group to increase production efficiencies through reducing the volatility of plant settings and consequently 
increase profit margins. The Group has finalised negotiations with shipments to commence in the final quarter of 2023. 
The  directors  anticipate  that  the  Group  will  be  able  to  renew  certain  borrowings  and  raise  significant  new  funding, 
whether through capital raisings, private placement or otherwise, in the  coming 12 months to progress development 
activities relating to the Donald Project and continue to meet its primary milestones in relation to the Project. 
•  An undertaking by the majority shareholder to provide financial support where necessary to enable the Group to meet 
its obligations and commitments until the Company is adequately financed. 
• 
The undertaking by a director not to demand repayments due to her and her related entities of approximately $8.0 million 
until such time when any repayment will not affect the Group’s ability to repay other creditors in the normal course of 
business (refer note 31). 
Assuming the plans and measures in the forecast can be successfully implemented as scheduled, the directors are of the 
opinion  that  the  Group  will  have  sufficient  working  capital  over  the  forecast  period  to  finance  its  operations  and  fulfil  its 
financial  obligations  as  and  when  they  fall  due.  Accordingly,  the  directors  of  the  Group  consider  that  it  is  appropriate  to 
prepare the consolidated financial statements on a going concern basis notwithstanding that there is a material uncertainty 
relating to the above events or conditions that may cast significant doubt as to the Group’s ability to continue as a going 
concern and, therefore, that it may be unable to realise its assets and discharge its liabilities in the normal course of business. 
Should the Group fail to achieve the plans and measures as scheduled, it might not be able to continue as a going concern, 
and adjustments would have to be made to reduce the value of assets to their net realisable amounts, to reclassify non-
current assets and non-current liabilities as current assets and current liabilities respectively and to provide for any further 
liabilities  which  might  arise.  The  effect  of  these  adjustments  has  not  been  reflected  in  these  consolidated  financial 
statements.

Notes to the Consolidated Financial Statements 
For the year ended 30 June 2023 
Significant accounting policies 
The  following  significant  accounting  policies  have  been  adopted  in  the  preparation  and  presentation  of  the  financial 
statements. 
Basis of consolidation 
The  Group  financial  statements  consolidate  those  of  the  Company  and  all  of  its  subsidiaries  as  at  30  June  2023.  The 
Company controls a subsidiary if it is exposed, or has rights, to variable returns from its involvement with the subsidiary and 
has the ability to affect those returns through its power over the subsidiary. 
All transactions and balances between Group companies are eliminated on consolidation, including unrealised gains and 
losses  on  transactions  between  Group  companies.  Where  unrealised  losses  on  intra-group  asset  sales  are  reversed  on 
consolidation, the underlying asset is also tested for impairment from a Group perspective. Amounts reported in the financial 
statements of subsidiaries have been adjusted where necessary to ensure consistency with the accounting policies adopted 
by the Group. 
Profit or loss and other comprehensive income of subsidiaries acquired or disposed of during the year are recognised from 
the effective date of acquisition, or up to the effective date of disposal, as applicable. 
Foreign currency translation 
The functional and presentation currency of the Company and its Australian subsidiaries is Australian dollars ($). 
Foreign currency transactions are translated into the functional currency using the exchange rates ruling at the date of the 
transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated at the rate of exchange ruling 
at the end of the reporting period. Foreign exchange gains and losses resulting from settling foreign currency transactions, 
as well as from restating foreign currency denominated monetary assets and liabilities, are recognised in profit or loss except 
when they are deferred in other comprehensive income as qualifying cash flow hedges or where they relate to differences 
on foreign currency borrowings that provide a hedge against a net investment in a foreign entity. 
Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when 
fair value was determined. 
The functional currency of the overseas subsidiaries is primarily Chinese Renminbi (RMB). The assets and liabilities of these 
overseas  subsidiaries  are  translated  into  the  presentation  currency  of  the  Company  at  the  closing  rate  at the  end  of  the 
reporting period and income and expenses are translated at the weighted average exchange rates for the year. All resulting 
exchange differences are recognised in other comprehensive income as a separate component of equity (foreign currency 
translation  reserve).  On  disposal  of  a  foreign  entity,  the  cumulative  exchange  differences  recognised  in  foreign  currency 
translation reserves relating to that particular foreign operation are recognised in the profit or loss. 
Revenue recognition 
Revenue is recognised at the fair value of the consideration received or receivable. Amounts disclosed as revenue are net 
of returns, trade allowances and duties and taxes paid. The following specific recognition criteria must also be met before 
revenue is recognised: 
Sale of goods 
Revenue from contracts with customers is recognised when control of goods or services is transferred to the customers at 
an amount that reflects the consideration to which the Group expects to be entitled in exchange for those goods or services, 
excluding those amounts collected on behalf of third parties. Revenue excludes value added tax or other sales taxes and is 
after deduction of any trade discounts. 
Depending  on  the  terms  of  the  contract  and  the  laws  that  apply  to  the  contract,  control  of  the  goods  or  service  may  be 
transferred over time or at a point in time. Control of the goods or service is transferred over time if the Group’s performance: 
• 
• 
• 
provides all of the benefits received and consumed simultaneously by the customer; 
creates or enhances an asset that the customer controls as the Group performs; or 
does not create an asset with an alternative use to the Group and the Group has an enforceable right to payment for 
performance completed to date. 
If control of the goods or services transfers over time, revenue is recognised over the period of the contract by reference to 
the progress towards complete satisfaction of that performance obligation. Otherwise, revenue is recognised at a point in 
time when the customer obtains control of the goods or service.

Notes to the Consolidated Financial Statements 
For the year ended 30 June 2023 
When the contract contains a financing component which provides the customer a significant benefit of financing the transfer 
of goods or services to the customer for more than  one year, revenue is measured at the present value of the amounts 
receivable, discounted using the discount rate that would be reflected in a separate financing transaction between the Group 
and  the  customer  at  contract  inception.  Where  the  contract  contains  a  financing  component  which  provides  a  significant 
financing benefit to the Group, revenue recognised under that contract includes the interest expense accreted on the contract 
liability under the effective interest method. For contracts where the period between the payment and the transfer of the 
promised goods or services is one year or less, the transaction price is not adjusted for the effects of a significant financing 
component, using the practical expedient in HKFRS 15. 
Customers obtain control of the goods when the goods are delivered to and have been accepted. Revenue is thus recognised 
upon when the customers accepted the goods. There is generally only one performance obligation. 
Contract liabilities 
A  contract  liability  represents  the  Group’s  obligation  to  transfer  goods  to  a  customer  for  which  the  Group  has  received 
consideration (or an amount of consideration is due) from the customer. 
Interest income 
Interest  income  is  recognised  as  it  accrues  using  the  effective  interest  method.  The  effective  interest  method  uses  the 
effective interest rate which is the rate that exactly discounts the estimated future cash receipts over the expected life of the 
financial asset. 
Rental income 
Rental income is accounted for on a straight-line basis over the lease term. Contingent rentals are recognised as income in 
the periods when they are earned. 
Income tax 
The income tax expense for the year is the tax payable on the current year's taxable income based on the national income 
tax rate for each jurisdiction adjusted by changes in deferred tax assets and liabilities attributable to temporary differences 
between  the  tax  base  of  assets  and  liabilities  and  their  carrying  amounts  in  the  financial  statements,  and  to  unused  tax 
losses. 
Deferred  tax  assets  and  liabilities  are  recognised  for  all  temporary  differences,  between  carrying  amounts  of  assets  and 
liabilities for financial reporting purposes and their respective tax bases, at the tax rates expected to apply when the assets 
are recovered or liabilities settled, based on those tax rates which are enacted or substantively enacted for each jurisdiction. 
Exceptions are made for certain temporary differences arising on initial recognition of an asset or a liability if they arose in a 
transaction, other than a business combination, that at the time of the transaction did not affect either accounting profit or 
taxable profit. 
Deferred tax assets are only recognised for deductible temporary differences and unused tax losses if it is probable that 
future taxable amounts will be available to utilise those temporary differences and losses. 
Deferred tax assets and liabilities are not recognised for temporary differences between the carrying amount and tax bases 
of investments in subsidiaries, associates and interests in joint ventures where the parent entity is able to control the timing 
of the reversal of the temporary differences and it is probable that the differences will not reverse in the foreseeable future. 
The Group has implemented the tax consolidation legislation for the whole of the financial year. The stand-alone taxpayer 
within a group approach has been used to allocate current income tax expense and deferred tax balances to wholly owned 
subsidiaries that form part of the tax consolidated group where the head entity has assumed all the current tax liabilities and 
the  deferred  tax  assets  arising  from  unused  tax  losses  for  the  tax  consolidated  group  via  intercompany  receivables  and 
payables because a tax funding arrangement has been in place for the whole financial year. The amounts receivable/payable 
under tax funding arrangements are due upon notification by the head entity, which is issued soon after the end of each 
financial year. Interim funding notices may also be issued by the head entity to its wholly owned subsidiaries in order for the 
head  entity  to  be  able  to  pay  tax  instalments.  These  amounts  are  recognised  as  current  intercompany  receivables  or 
payables. 
To the extent that research and development costs are eligible activities under the “Research and development tax incentive” 
programme,  a  43.5%  refundable  tax  offset  is  available  for  companies  with  annual  turnover  of  less  than  $20  million. The 
Group recognises refundable tax offsets received in the financial year as an income tax benefit, in profit or loss.

Financial instruments 
Financial assets 
A financial asset (unless it is a trade receivable without a significant financing component) is initially measured at fair value 
plus, for an item not at fair value through profit or loss (FVTPL), transaction costs that are directly attributable to its acquisition 
or issue. A trade receivable without a significant financing component is initially measured at the transaction price. 
All regular way purchases and sales of financial assets are recognised on the trade date, that is, the date that the Group 
commits to purchase or sell the asset. Regular way purchases or sales are purchases or sales of financial assets that require 
delivery of assets within the period generally established by regulation or convention in the marketplace. 
Equity instruments 
On  initial  recognition  of  an  equity  investment  that  is  not  held  for  trading,  the  Group  could  irrevocably  elect  to  present 
subsequent changes in the investment’s fair value in other comprehensive income. This election is made on an investment-
by-investment  basis.  Equity  investments  at  fair  value  through  other  comprehensive  income  are  measured  at  fair  value. 
Dividend income is recognised in profit or loss unless the dividend income clearly represents a recovery of part of the cost 
of the investments. Other net gains and losses are recognised in other comprehensive income and are not reclassified to 
profit or loss. All other equity instruments are classified as FVTPL, whereby changes in fair value, dividends and interest 
income are recognised in profit or loss. 
Impairment loss on financial assets 
The Group recognises loss allowances for expected credit loss (ECL) on trade receivables, other receivables, and other 
financial assets measured at amortised cost. The ECLs are measured on either of the following bases: (1) 12 months ECLs: 
these are the ECLs that result from possible default events within the 12 months after the reporting date: and (2) lifetime 
ECLs:  these  are  ECLs  that  result  from  all  possible  default  events  over  the  expected  life  of  a  financial  instrument.  The 
maximum period considered when estimating ECLs is the maximum contractual period over which the Group is exposed to 
credit risk. 
ECLs  are  a  probability-weighted  estimate  of  credit  losses.  Credit  losses  are  measured  as  the  difference  between  all 
contractual cash flows that are due to the Group in accordance with the contract and all the cash flows that the Group expects 
to receive. The shortfall is then discounted at an approximation to the assets’ original effective interest rate. 
For  trade  receivables,  the  Group  applies  the  simplified  approach  and  has  calculated  ECLs  based  on  lifetime  ECLs.  The 
Group has established a provision matrix that is based on the Group’s historical credit loss experience, adjusted for forward-
looking factors specific to the debtors and the economic environment. 
For other debt financial assets, the ECLs are based on the 12-months ECLs. However, when there has been a significant 
increase in credit risk since origination, the allowance will be based on the lifetime ECLs. 
When determining whether the credit risk of a financial asset has increased significantly since initial recognition and when 
estimating ECL, the Group considers reasonable and supportable information that is relevant and available without undue 
cost or effort. This includes both quantitative and qualitative information analysis, based on the Group’s historical experience 
and informed credit assessment and including forward-looking information. 
The Group assumes that the credit risk on a financial asset has increased significantly if it is more than 30 days past due. 
The Group considers a financial asset to be credit-impaired when: (1) the borrower is unlikely to pay its credit obligations to 
the Group in full, without recourse by the Group to actions such as realising security (if any is held); or (2) the financial asset 
is more than 90 days past due. 
Interest income on credit-impaired financial assets is calculated based on the amortised cost (i.e. the gross carrying amount 
less loss allowance) of the financial asset. For non-credit impaired financial assets interest income is calculated based on 
the gross carrying amount. 
Financial liabilities 
The  Group  classifies  its  financial  liabilities,  depending  on  the  purpose  for  which  the  liabilities  were  incurred.  Financial 
liabilities at fair value through profit or loss are initially measured at fair value and financial liabilities at amortised costs are 
initially measured at fair value, net of directly attributable costs incurred.

Notes to the Consolidated Financial Statements 
For the year ended 30 June 2023 
Financial liabilities at amortised cost 
Financial liabilities at amortised cost including trade and other payables, borrowings and the debt element of convertible 
notes issued by the Group are subsequently measured at amortised cost, using the effective interest method. The related 
interest expense is recognised in profit or loss. 
Gains or losses are recognised in profit or loss when the liabilities are derecognised as well as through the amortisation 
process. 
Convertible notes 
Convertible  notes  issued  by  the  Group  that  contain  both  the  liability  and  conversion  option  components  are  classified 
separately into their respective items on initial recognition. Conversion option that will be settled by the exchange of a fixed 
amount of cash or another financial asset for a fixed number of the Company’s own equity instruments is classified as an 
equity instrument. 
On initial recognition, the fair value of the liability component is determined using the prevailing market interest rate of similar 
non-convertible debts. The difference between the proceeds of the issue of the convertible notes and the fair value assigned 
to the liability component, representing the conversion option for the holder to convert the notes into equity, is included in 
equity (convertible notes equity reserve). 
In subsequent periods, the liability component of the convertible notes is carried at amortised cost using the effective interest 
method.  The  equity  component,  represented  by  the  option  to  convert  the  liability  component  into  ordinary  shares  of  the 
Company, will remain in convertible notes equity reserve until the embedded option is exercised (in which case the balance 
stated in convertible notes equity reserve will be transferred to issued capital. Where the option remains unexercised at the 
expiry dates, the balance stated in convertible notes equity reserve will be released to the retained earnings. No gain or loss 
is recognised upon conversion or expiration of the option. 
Transaction  costs  that  relate  to  the  issue  of  the  convertible  notes  are  allocated  to  the  liability  and  equity  components  in 
proportion to the allocation of the proceeds. Transaction costs relating to the equity component are charged directly to equity. 
Transaction costs relating to the liability component are included in the carrying amount of the liability portion and amortised 
over the period of the convertible notes using the effective interest method. 
Effective interest method 
The effective interest method is a method of calculating the amortised cost of a financial asset or financial liability and of 
allocating interest income or interest expense over the relevant period. The effective interest rate is the rate that exactly 
discounts estimated future cash receipts or payments through the expected life of the financial asset or liability, or where 
appropriate, a shorter period. 
Equity instruments 
Equity instruments issued by the Company are recorded at the proceeds received, net of direct issue costs. 
The  Hong  Kong  Companies  Ordinance,  Cap.  622  (the  Ordinance),  came  into  operation  on  3  March  2014.  Under  the 
Ordinance, shares of the Company do not have a nominal value. Consideration received or receivable for the issue of shares 
on or after 3 March 2014 is credited to share capital. Commissions and expenses are allowed to be deducted from share 
capital under s. 148 and s. 149 of the Ordinance. 
Derecognition 
The Group derecognises a financial asset when the contractual rights to the future cash flows in relation to the financial asset 
expire or when the financial asset has been transferred and the transfer meets the criteria for derecognition in accordance 
with HKFRS 9. 
Financial  liabilities  are  derecognised  when  the  obligation  specified  in  the  relevant  contract  is  discharged,  cancelled  or 
expires. 
Cash and cash equivalents 
For the purposes of the Consolidated Statement of Cash Flows, cash and cash equivalents includes cash on hand and at 
banks,  deposits  held  at  call  with  financial  institutions,  other  short  term,  highly  liquid  investments  with  maturities  of  three 
months or less, that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes 
in value and bank overdrafts. 
For the purpose of the Consolidated Statement of Cash Flows, movements in term deposits with maturity over three months 
are shown as cash flows from investing activities.

Inventories 
Inventories are stated at the lower of cost and net realisable value. Cost comprises all direct materials, direct labour and an 
appropriate portion of variable and fixed overheads. Fixed overheads are allocated on the basis of normal operating capacity. 
Costs are assigned to inventories using the weighted average cost basis. Net realisable value is the estimated selling price 
in the ordinary course of business, less the estimated selling cost of completion and selling expenses. 
Property, plant and equipment 
Each class of property, plant and equipment is carried at cost less, where applicable, any accumulated depreciation and 
impairment losses. 
All  other  plant  and  equipment  is  stated  at  historical  cost,  including  costs  directly  attributable  to  bringing  the  asset  to  the 
location and condition necessary for it to be capable of operating in the manner intended by management, less depreciation 
and any impairments. 
Freehold land is not depreciated. Leasehold improvements are depreciated over the shorter of either the unexpired period 
of the lease or the estimated useful lives of the improvements. 
Depreciation on other assets is calculated on a straight-line basis over the estimated useful life of the asset as follows: 
Class of Asset 
Leasehold buildings 
Freehold land 
Plant and equipment 
50 years 
Indefinite 
3-20 Years 
The assets' residual value and useful lives are reviewed, and adjusted if appropriate, at the end of each reporting period. 
Gains and losses on disposals are calculated as the difference between the net disposal proceeds and the asset's carrying 
amount and are included in profit or loss in the year that the item is de-recognised. 
The cost of fixed assets constructed within the Group includes the cost of materials, direct labour, borrowing costs (if any) 
and an appropriate proportion of fixed and variable overheads. 
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. 
Additional costs incurred on impaired capital works in progress are expensed in profit or loss. 
Leases 
All leases (irrespective of whether they are operating leases or finance leases) are required to be capitalised in the statement 
of financial position as right-of-use assets and lease liabilities, but accounting policy choices exist for an entity to choose not 
to capitalise (i) leases which are short-term leases and/or (ii) leases for which the underlying asset is of low-value. The Group 
has elected not to recognise right-of-use assets and lease liabilities for which at the commencement date have a lease term 
of 12 months or less. The lease payments associated with those leases have been expensed on straight-line basis over the 
lease term. 
Right-of-use asset 
The right-of-use asset should be recognised at cost and would comprise: (i) the amount of the initial measurement of the 
lease liability; (ii) any lease payments made at or before the commencement date, less any lease incentives received; (iii) 
any initial direct costs incurred by the lessee and (iv) an estimate of costs to be incurred by the lessee in dismantling and 
moving  the  underlying  asset  to  the  condition  required  by  the  terms  and  conditions  of  the  lease,  unless  those  costs  are 
incurred to produce inventories. Except for right-of-use asset that meets the definition of an investment property or a class 
of property, plant and equipment to which the Group applies the revaluation model, the Group measures the right-of-use 
assets  applying  the  cost  model.  Under  the  cost  model,  the  Group  measures  the  right-of-use  assets  at  cost,  less  any 
accumulated depreciation and any impairment losses, and adjusted for any remeasurement of lease liability. Lease assets 
are depreciated on a straight-line basis over their expected useful lives on the same basis as owned assets, or where shorter, 
the term of the relevant lease. 
The following payments for the underlying right-of-use asset during the lease term that are not paid at the commencement 
date of the lease are considered to be lease payments: (i) fixed payments less any lease incentives receivable; (ii) variable   
lease payments that depend on an index or a rate, initially measured using the index or rate as the commencement date; 
(iii) amounts expected to be payable by the lessee under residual value guarantees; (iv) the exercise price of a purchase

option if the lessee is reasonably certain to exercise that option and (v) payments of penalties for terminating the lease, if 
the lease term reflects the lessee exercising an option to terminate the lease. 
Intangibles 
Research and development costs 
Research costs are expensed as incurred. Development costs incurred on an individual project is capitalised if the product 
or service is technically feasible, adequate resources are available to complete the project, it is probable that future economic 
benefits  will  be  generated  and  expenditure  attributable  to  the  project  can  be  measured  reliably.  Expenditure  capitalised 
comprises costs of services and direct labour. Other development costs are expensed when they are incurred. The carrying 
value of development costs is reviewed annually when the asset is not yet available for use, or when events or circumstances 
indicate that the carrying value may be impaired. 
Capitalised  development  costs  are  amortised  over  the  periods  the  Group  expects  to  benefit  from  selling  the  products 
developed. The amortisation expense is recognised in profit or loss. 
Exploration and Evaluation Expenditure 
Costs carried forward 
Costs arising from exploration and evaluation activities are carried forward provided that the rights to tenure of the area of 
interest  are  current  and  such  costs  are  expected  to  be  recouped  through  successful  development,  or  by  sale,  or  where 
exploration and evaluation activities have not, at reporting date, reached a stage to allow a reasonable assessment regarding 
the existence of economically recoverable reserves. Expenditure incurred is accumulated in respect of each identifiable area 
of interest. 
Water rights 
The Group has capitalised water rights. The water rights are amortised over the term of the right. The carrying value of water 
rights is reviewed annually or when events or circumstances indicate that the carrying value may be impaired. 
Costs abandoned area 
Costs carried forward in respect of an area of interest that is abandoned are written off in the year in which the decision to 
abandon is made. 
Regular review 
A regular review is undertaken of each area of interest to determine the appropriateness of continuing to carry forward costs 
in relation to that area of interest. 
Costs of site restoration 
Costs of site restoration are to be provided once an obligation presents. Site restoration costs include the dismantling and 
removal of mining plant, equipment and building structures, waste removal and rehabilitation of the site in accordance with 
clauses of the mining permits. Such costs will be determined using estimates of future costs, current legal requirements and 
technology on a discounted basis. 
Impairment of assets 
At the end of each reporting period, the Group assesses whether there is any indication that individual assets are impaired. 
Where impairment indicators exist, recoverable amount is determined and impairment losses are recognised in the profit or 
loss where the asset's carrying value exceeds its recoverable amount. Recoverable amount is the higher of an asset's fair 
value less costs to sell and value in use. For the purpose of assessing value in use, the estimated future cash flows are 
discounted to their present value using a pretax discount rate that reflects current market assessments of the time value of 
money and the risks specific to the asset. 
Where it is not possible to estimate recoverable amount for an individual asset, recoverable amount is determined for the 
cash generating unit to which the asset belongs. 
Borrowing costs 
Borrowing costs directly attributable to the acquisition, construction or production of assets that necessarily take a substantial 
period of time to prepare for their intended use or sale, are added to the cost of those assets, until such time as the assets 
are substantially ready for their intended use or sale. 
All other borrowing costs are recognised in profit or loss in the period in which they are incurred.

Notes to the Consolidated Financial Statements

Provisions 
Provisions for legal claims, service warranties and make good obligations are recognised when the Group has a present 
legal or constructive obligation as a result of a past event, it is probable that that an outflow of economic resources will be 
required to settle the obligation and the amount can be reliably estimated. Provisions are not recognised for future operating 
losses. 
Where the effect of the time value of money is material, provisions are determined by discounting the expected future cash 
flows at a pretax rate that reflects current market assessments of the time value of money and, where appropriate, the risks 
specific to the liability. 
Employee benefit provisions 
Wages and salaries, annual leave and sick leave 
Liabilities for wages and salaries, including non-monetary benefits, annual leave and accumulating sick leave expected to 
be settled within 12 months of the end of the reporting period are recognised in respect of employees' services rendered up 
to the end of the reporting period and measured at amounts expected to be paid when the liabilities are settled. Liabilities 
for  non-accumulating  sick  leave  are  recognised  when  leave  is  taken  and  measured  at  the  actual  rates  paid  or  payable. 
Liabilities for wages and salaries and annual leave are included as part of Other Payables. 
Bonus plan 
The Group recognises an expense and a liability for bonuses when the entity is contractually obliged to make such payments 
or where there is past practice that has created a constructive obligation. 
Retirement benefit obligations 
The  Group  contributes  to  employee  superannuation  funds  in  accordance  with  its  statutory  obligations.  Contributions  are 
recognised as expenses as they become payable. 
Share-based payments 
The  Group  may  provide  benefits  to  employees  (including  directors)  of  the  Group  in  the  form  of  share-based  payment 
transactions, whereby employees render services in exchange for shares (equity settled transactions). Such equity settled 
transactions are at the discretion of the Nomination & Remuneration Committee. 
The fair value of options or rights granted is recognised as an employee benefit expense with a corresponding increase in 
equity (share-based payment reserve). The fair value is measured at grant date and recognised over the period during which 
the employees become unconditionally entitled to the options. Fair value is determined using a Black-Scholes option pricing 
model. In determining fair value, no account is taken of any performance conditions other than those related to the share 
price of Astron Corporation Limited (market conditions). The cumulative expense recognised between grant date and vesting 
date is adjusted to reflect the directors’ best estimate of the number of options or rights that will ultimately vest because of 
internal conditions of the options or rights, such as the employees having to remain with the Group until vesting date, or such 
that employees are required to meet internal KPI. No expense is recognised for options or rights that do not ultimately vest 
because  internal  conditions  were  not  met.  An  expense  is  still  recognised  for  options  or  rights  that  do  not  ultimately  vest 
because a market condition was not met. 
Where the terms of options or rights are modified, the expense continues to be recognised from grant date to vesting date 
as if the terms had never been changed. In addition, at the date of the modification, a further expense is recognised for any 
increase in fair value of the transaction as a result of the change. 
Where options are cancelled, they are treated as if vesting occurred on cancellation and any unrecognised expenses are 
taken immediately to profit or loss. However, if new options are substituted for the cancelled options or rights and designated 
as  a  replacement  on  grant  date,  the  combined  impact  of the  cancellation  and  replacement  are  treated  as  if  they  were  a 
modification. 
When shareholders’ approval is required for the issuance of options or rights, the expenses are recognised based on the 
grant-date fair value according to the management estimation. This estimate is re-assessed upon obtaining formal approval 
from shareholders. 
Where  equity  instruments  are  granted  to  persons  other  than  employees,  the  consolidated  statement  of  comprehensive 
income is charged with the fair value of goods and services received. 
Dividends/Return of capital 
No dividends were paid or proposed for the years ended 30 June 2023 and 30 June 2022. There is no Dividend Reinvestment 
Plan in operation.

Segment reporting 
Segment revenues, expenses, assets and liabilities are those that are directly attributable to a segment and the relevant 
portion that can be allocated to the segment on a reasonable basis. Segment assets include all assets used by a segment 
and consist primarily of operating cash, receivables, inventories, property, plant and equipment and other intangible assets. 
Segment liabilities consist primarily of trade and other creditors, employee benefits and provisions. 
Earnings per share 
Basic earnings per share 
Basic earnings per share is calculated by dividing the profit attributable to owners of the Company by the weighted average 
number of ordinary shares outstanding during the financial year, adjusted for bonus elements in ordinary shares during the 
year. 
Diluted earnings per share 
Earnings used to calculate diluted earnings per share are calculated by adjusting the basic earnings by the after-tax effect 
of dividends and interest associated with dilutive potential ordinary shares. The weighted average number of shares used is 
adjusted  for  the  weighted  average  number  of  ordinary  shares  that  would  be  issued  on  the  conversion  of  all  the  dilutive 
potential ordinary shares into ordinary shares. 
Goods and Services Tax (GST)/Value Added Tax (VAT) 
Revenues, expenses are recognised net of GST/VAT except where GST/VAT incurred on a purchase of goods and services 
is not recoverable from the taxation authority, in which case the GST/VAT is recognised as part of the cost of acquisition of 
the asset or as part of the expense item. 
Receivables and payables are stated with the amount of GST/VAT included. The net amount of GST/VAT recoverable from, 
or payable to, the taxation authority is included as part of receivables or payables in the consolidated statement of financial 
position. 
Commitments and contingencies are disclosed net of the amount of GST/VAT recoverable from, or payable to, the taxation 
authority. 
Government grant 
Government grants are not recognised until there is reasonable assurance that the Group will comply with the conditions 
attaching  to  them  and  that  the  grants  will  be  received.  Grants  that  compensate  the  Group  for  expenses  incurred  are 
recognised as income or deducted in the related expenses, as appropriate, in profit or loss on a systematic basis in the same 
periods in which the expenses are incurred. 
Grants that compensate the Group for the cost of an asset are recognised as deferred income in the consolidated statement 
of financial position and transferred to profit or loss on a systematic and rational basis over the useful lives of the related 
assets. 
Government grants that are receivable as compensation for expenses or losses already incurred or for the purpose of giving 
immediate financial support to the Group with no future related costs are recognised in profit or loss in the period in which 
they become receivable and are recognised as other income, rather than reducing the related expense.

In  the  application  of  the  Group’s  accounting  policies,  the  directors  are  required  to  make  judgements,  estimates  and 
assumptions  about  the  carrying  amounts  of  assets  and  liabilities  that  are  not  readily  apparent  from  other  sources.  The 
estimates  and  associated  assumptions  are  based  on  historical  experience  and  other  factors  that  are  considered  to  be 
relevant. Actual results differ from these estimates. 
The  estimates  and  underlying  assumptions  are  reviewed  on  an  ongoing  basis.  Revisions  to  accounting  estimates  are 
recognised in the period in which the estimate is revised if the revision affects only that period or in the period of the revision 
and future periods if the revision affects both current and future periods. 
Impairment assessment of intangible assets and property, plant and equipment (PPE) 
The Group assesses impairment at the end of each reporting period by evaluating conditions specific to the Group that may 
lead to impairment of intangible assets and PPE. Where an impairment trigger exists, the recoverable amount of the asset 
is determined. Fair value less costs to dispose calculations are performed in assessing recoverable amounts incorporate a 
number of key estimates and judgements. 
The Group has used a combination of independent and director valuations to support the carrying value of intangible assets 
while the Group also uses bankable feasibility status reports where these are available. The Group’s main intangible assets 
are its exploration and evaluation assets related to the Donald project located in Victoria, Australia and its development costs 
incurred on the Niafarang project in Senegal. The valuations use various assumptions to determine future cash flows based 
around risks including capital, geographical, markets, foreign exchange and mineral price fluctuations. 
All other assets have been assessed for impairment based on either their value in use or fair value less costs to sell. The 
impairment assessments inherently involve significant judgements and estimates to be made. 
Capitalisation of exploration and evaluation assets 
The  Group  has  continued  to  capitalise  expenditure,  incurred  on  the  exploration  and  evaluation  of  the  Donald  project  in 
Victoria, Australia in accordance with HKFRS 6. This has occurred because the technical feasibility and economic viability 
of extracting the mineral resources have not been completed and hence are not demonstrable at this time. The Group has 
assessed that the balances capitalised will be recoverable through the project’s successful development.

Notes to the Consolidated Financial Statements 
For the year ended 30 June 2023 
Capitalisation of Development Assets 
The  Group  has  continued  to  capitalise  expenditure,  in  accordance  with  HKAS  38,  incurred  on  the  development  of  the 
Niafarang  Mineral  Sands  project  in  Senegal.  The  Group  has  assessed  that  the  balances  capitalised  will  be  recoverable 
through the project’s successful development. 
Provision for expected credit losses of receivables 
The  provision  for  impairment  of  receivables  assessment  requires  a  degree  of  estimation  and  judgement.  The  level  of 
provision is assessed by taking into account the recent sales experience, the aging of receivables, historical collection rates 
and specific knowledge of the individual debtors’ financial position. The Group has an outstanding receivable for the disposal 
of surplus land in China from 2015, further details of which are set out in note 11. The Group is confident the balance of $0.9 
million due at year end (2022: $1.1 million) will be settled within the next twelve months. 
Income tax 
The Group is subject to income taxes in the jurisdictions in which it operates. Significant judgment is required in determining 
the provision for income tax. There are transactions and calculations undertaken during the ordinary course of business for 
which the ultimate tax determination is uncertain. The Group recognises tax receivables and liabilities based on the Group’s 
current understanding of the tax law. Where the final tax outcome of these matters is different from the carrying amounts, 
such differences will impact the current and deferred tax provisions in the period in which such determination is made. 
Deferred tax assets 
Deferred tax assets have not been recognised for capital losses and revenue losses as the utilisation of these losses is not 
considered probable at this stage. 
Inventories 
Management estimates the net realisable values of inventories, taking into account the most reliable evidence available at 
each reporting date. The future realisation of these inventories may be affected by future technology or other market-driven 
changes that may reduce future selling prices. 
Going concern basis 
These consolidated financial statements have been prepared on a going concern basis, the validity of which depends upon 
the financing plan assessed as detailed in note 2 to these consolidated financial statements. However, because not all future 
events or conditions can be predicted, this assumption is not a guarantee as to the Group’s and Company’s ability to continue 
as a going concern. 
4.  Segment information 
Description of segments 
The Group has adopted HKAS 8 Operating Segments from whereby segment information is presented using a 'management 
approach', i.e. segment information is provided on the same basis as information used for internal reporting purposes by the 
Managing  Director/President  (chief  operating  decision  maker)  who  monitors  the  segment  performance  based  on  the  net 
profit before tax for the period. Operating segments have been determined on the basis of reports reviewed by the Managing 
Director/President who is considered to be the chief operating decision maker of the Group. The reportable segments are 
as follows: 
•  Donald Rare Earths & Mineral Sands (DMS): Development of the DMS mine 
•  China: Development and construction of mineral processing plant and mineral trading 
•  Senegal: Development of the Niafarang mine 
•  Other: Group treasury and head office activities

During the year ended 30 June 2014, the Group entered into an agreement to transfer 1,065,384m² of land held in Yingkou 
Province in China to a state-owned entity. As the under-development of this land resulted from a change of government 
development plans and restructure, this land transfer has been subsidised by the Chinese Government. Final contracts over 
the  land  sale  have  been  exchanged  and  the  disposal  was  brought  to  account  in  the  year  ended  30  June  2015.  The  net 
proceeds  receivable  amounted  to  $20,356,248.  The  land  contract  is  unconditional,  and  payment  is  binding  on  the  buyer 
being the Yingkou Government and its related entities, but the payments expected have been delayed. 
The receivable is currently outside the terms initially agreed. 
As at 30 June 2023, the total amount outstanding before ECL provision was $1,095,945 (2022: $1,141,839). There were no 
amounts received during the years ended 30 June 2022 and 2023. The directors continue to believe this remaining balance 
will be recovered in full as it is owed by a Chinese government entity but estimate it will now be settled in 2024 or 2025. The 
provision has accordingly been determined on that basis and as such a further provision for expected credit loss of $118,716 
(2022: $6,755) was recognised for the year ended 30 June 2023. As at 30 June 2023, the impairment provision for land sale 
receivable was $164,392 (2022: $50,812).

At the end of the reporting period, the Group’s trade debtors were predominantly receivable from Chinese trading partners. 
The Chinese debtors are regularly reviewed and, as is common practice in China, the terms may be extended to preserve 
client relationships. Where applicable, the Group has impaired significantly overdue receivables. 
It  is  the  Group’s  policy  that,  where  possible,  sales  are  made  in  exchange  for  notes  (guaranteed  by  a  Chinese  bank), 
minimising the Group’s exposure to an impairment issue. 
Impairment on trade debtors 
At year end, the Group reviewed its trade debtors and brought to account impairment where required. 
As at 30 June 2023, the impairment provision for trade debtors was $39,058 (2022: $40,693). 
Prepayments 
At year end, the Group had made advances for property, plant and equipment purchases. 
Included in prepayments is an amount of RMB1,800,000 carried forward from 2008, equivalent to $374,384 (2022: $390,062) 
which is the prepayment for construction. This amount has been fully impaired due to low possibility of collection.

Investments in Gambia 
Carnegie Minerals (Gambia) Limited is a 100% subsidiary of the Company. It was incorporated to commence mining activities 
in  Gambia.  The  investments  and  receivables  associated  with  the  Company  have  been  impaired  in  full.  The  original 
agreement prior to the seizure of the assets was that Astron  Pty Limited had an obligation to fund the development and 
operating costs of the mine by way of loans. 
As announced to the ASX on 23 July 2015, the Group has received a successful finding in its favour. The Group and the 
Gambian  government  made  submissions  on  damages  to  the  International  Centre  for  Settlement  of  Investment  Disputes 
(ICSID). ICSID has determined the award including damages in favour of Astron. 
The determination was for US$18,658,358 in damages for breach of the mining licence, interest of US$993,683, arbitration 
costs of US$445,860 (minus any sums refunded to Astron by ICSID on its final accounting) and £2,250,000 for legal costs. 
In total this is approximately A$31 million. 
On 2 December 2015, the Group notified the ASX that Gambia had submitted an application for annulment to ICSID, on the 
grounds  of  the  constitution  of  the  arbitral  tribunal,  and  arguments  about  admissibility  and  jurisdiction.  An  application  for 
annulment is the only form of action open to Gambia under the ICSID rules, as there is no form of appeal process. 
The ICSID panel of three arbitrators has confirmed that the Award should not be annulled in whole or in part in July 2020. 
The Group has been ordered to meet one half of the cost of the Committee being US$221,992 payable to Gambia and shall 
be offset against sums due under the Award. As of 30 June 2023, no assets arising from this matter were recognised.

For  the  year  ended  30  June  2023,  the  Group  incurred  $47,655  of  costs  in  relation  to  entering  into  a  litigation  funding 
agreement with an international law firm to attempt to expedite the recovery of this award. The litigation funder has agreed 
to incur up to US$2 million in recovery against the award with the parties to agree a budget for enforcement costs in for the

1.  The Group allocated the development costs in relation to the mineral separation plant (MSP) in China to capital works in progress. 
The MSP was commissioned in the year ended 30 June 2022, and the development expenditure was transferred from capital works 
in progress to buildings accordingly. 
2.  During the year ended 30 June 2022, the Group brought to account an impairment provision against the carrying value of construction 
in progress assets of $1,755,249. This was substantially an impairment of Chinese assets associated with a discontinued production 
line, being the Zircon Opacifier project, which can generate cash inflows independently of other assets. The Board determined that it 
will  no  longer  continue  the  production  line  due  to  the  complexity  and  costs  of  bringing  to  market  and  its  recoverable  amount  is 
considered to be zero. In December 2021, the Board agreed that it would not proceed with the investment in the Zircon Opacifier 
project and focus on the current operating separation and aggregation plant together with the trading and as such brought to account 
the impairment. 
3.  During the year ended 30 June 2023, following reconciliation of the fixed asset register to underlying source documents, depreciation 
previously classified as relating to buildings was discovered to be related to plant and equipment. As such, an amount of $247,219 
has been transferred between the two asset classifications at 30 June 2023.

This expenditure relates to the Group's investment in the Donald Rare Earth and Mineral Sands Project. As at 30 June 
2023, the Group has complied with the conditions of the granting of MIN5532, RL 2002, RL2003 and EL5186. As such, 
the directors believe that the tenements are in good standing with the Department of Energy, Environment and Climate 
Action (Earth Resources Regulator) in Victoria, who administers the Mineral Resources Development Act 1990. 
During the year, DMS completed the Definitive Feasibility Study for MIN5532, the Pre-Feasibility Study for RL2002 and 
associated Mineral Resource and Ore Reserve updates for the project. In conjunction with the completion of the above, 
further work has been completed on mine design and planning, engineering, process flow testing, transport and logistics 
planning and market engagement. 
The recoverability of the carrying amount of the exploration and evaluation assets is dependent upon the successful 
development and commercial exploitation or alternatively sale of the area of interest. 
(c)  Water rights 
In 2012, the Group acquired rights to the supply of water for the Donald project. The water rights are amortised over 
25 years (subject to the extension of this term) in line with entitlements. 
In July 2018, a “Deed of Variation” was signed between Grampians Wimmera Mallee Water Corporation (GWM Water) 
and Donald Mineral Sands Pty Ltd., a wholly owned subsidiary of the Company. The variation provides for an extension 
of the term of the original agreement of up to four years subject to terms and conditions. The amortisation period of the 
water rights have accordingly been extended by four years to a total period of 29 years to December 2040.

The mining license of the Senegal project was granted in June 2017 (and subsequently renewed in 2023), the registered 
mining license was received in October 2017 and the environmental approval was obtained in August 2017. As a result of 
these  developments,  the  directors  considered  the  Senegal  project  had  demonstrated  it  was  technically  feasible  and 
commercially viable. Accordingly, under HKFRS 6 and the Group’s accounting policies, this project and the costs capitalised 
to date should no longer be accounted for as an exploration and evaluation asset, but rather as an asset in its own right. The 
costs associated with the Senegal project have therefore been classified as “Development costs” since the year ended 30 
June 2018.

During  the  year  ended  30  June  2014,  management  entered  into  an  agreement  to  transfer  1,065,384m²  of  land  held  in 
Yingkou  province  China  to  a  state-owned  entity,  representing  approximately  83%  of  the  total  land  held  by  the  Group  in 
Yingkou  province.  As  the  under-development  of  this  land  resulted  from  a  change  of  government  development  plan  and 
restructure,  this  land  transfer  has  been  subsidised  by  the  Chinese  Government.  Final  contracts  over  the  land  sale  were

or prospective participants who meet that criteria on appointment (Eligible Participant) (or the Eligible Associate of such
person) of the Company or an associated body corporate of the Company as the Board may in its discretion determine.
The maximum aggregate number of the options issued under the ESOP shall not at any time exceed 5% of the Company's
total issued shares (being up to 7,327,232 (2022: 6,123,988) options based on the number of issued shares outstanding at
30 June 2023). The exercise price of an Option is to be determined by the Board at its sole discretion.
The exercise period commences on the Option Commencement Date and ends on the earlier of:
•
•
•
•
the expiration of such period nominated by the Board at its sole discretion at the time of the grant of the Option but being
not less than two years;
an associated body corporate ceases because of an Uncontrollable Event, the earlier of:
a.
b.
the expiry of the Option Period; or
six months (or such other period as the Board shall, in its absolute discretion, determine) from the date on which
the Eligible Participant ceased that employment or engagement;
an associated body corporate ceases because of a Controllable Event, the earlier of:
a.
b.
the expiry of the Option Period; or
six months (or such other period as the Board shall, in its absolute discretion, determine) from the date on which
the Eligible Participant ceased that employment or engagement;
the Eligible Participant ceasing to be employed or engaged by the Company or an associated body corporate of the
Company due to fraud, dishonesty or being in material breach of their obligations to the Company or an associated body
corporate.

Issues ATRAA and ATRAB were agreed via separate director resolutions on 23 February 2021 (based on the share price at this date
of $0.225) and 20 July 2021 (based on the share  price at this date of $0.48) respectively. However, these issues were subject  to
shareholder approval and thus the grant date is taken to be the date of shareholder approval being on 30 November 2021.
An offer for the issue of 200,000 options under the ESOP to a consultant was declined during the year ended 30 June 2022. As such,
the number of options on issue at 30 June 2022 has been adjusted to reflect the fact that these options were never issued and therefore
were not outstanding at 30 June 2022.
Vesting Conditions 
There are no vesting conditions for issues ATRAA, ATRAB and ATRAD. All options issued under these tranches are free to 
be exercised from the date of issue.

Expected volatility (determined based on a statistical analysis of historical daily share prices over the same period as the life of the

1.  During year ended 30 June 2021, non-executive director Dr. Mark Elliott was granted 800,000 options subject to shareholder approval. 
As  at  30  June  2021,  the  Company  estimated  the  grant  date  fair  value  with  reference  to  the  fair  value  as  at  the  reporting  date 
(i.e. 30 June  2021)  to  be  $299,943  for  the  purpose  of  recognising  the  services  received  from  Dr.  Mark  Elliott.  Upon  receiving 
shareholder approval on 30 November 2021, the options were approved by the Board and the fair value of options granted to Dr. Mark 
Elliott was revalued to $229,308. As such, an adjustment to share-based payment expense of $70,635 was recognised in the profit or 
loss for the year ended 30 June 2022. 
1.  An offer for the issue of 200,000 options under the ESOP to a consultant was declined during the year ended 30 June 2022. However, 
the  share-based  payment  expense  relating  to  these  options  was  recognised  during  the  year  ended  30  June  2022.  As  such,  an 
adjustment to share-based payments expense has been recognised during the year ended 30 June 2023 in order to reflect the fact 
that these options were never issued and therefore the Company has not incurred any expense in relation to these options. 
The fair value of the share options granted during the year ended 30 June 2023 was $285,522 (30 June 2022: $619,688) 
(note  6)  which  had  been  recognised  as  employee  share  option  expense  with  the  corresponding  balance  credited  to  the 
share-based payment reserve. 
A share-based payment of $913,104 was recognised in 2017 after certain milestones with respect to the Senegal project 
were achieved by a project consultant. This represents a 3% equity interest in the project, calculated by reference to the 
Senegal project’s fair value and to be satisfied by the issue of shares in a Senegalese subsidiary.   
Broker options 
Pursuant  to  the  completion  of  the  private  placement  announced  by  the  Company  on  17  October  2022,  600,000  options 
exercisable at $0.81 expiring on 18 October 2025 were issued to Blue Ocean Equities nominee company L39 Pty Ltd in 
accordance  with  the  lead  manager  agreement  executed  by  the  Company  on  15  September  2022.  These  options  vest

Notes to the Consolidated Financial Statements 
For the year ended 30 June 2023 
Capital reserves 
Since at least 1 July 2014, the Company had entered into an unwritten informal agreement with Firback Finance Ltd (Firback) 
under which the services of Mr. Alex Brown, the former President, Managing Director and major shareholder of the Company 
until his death on 30 November 2019, was supplied to the Company (the Firback Contract). Under the terms of the Firback 
Contract, an accumulated amount of $1,450,005 was outstanding and due to Firback. Firback has since been wound up and 
no longer exists. It was further noted that prior to being wound up, Firback had not made any demand for payment of the 
balance outstanding, nor given notice of assignment of the outstanding amount to the Company so the Company considered 
the Firback contract expired during the year ended 30 June 2021. The amount owing to Firback was accordingly transferred 
to  capital  reserve  during  the  year  ended  30  June  2021.  The  reserve  balance  at  30  June  2023  was  $1,450,005  (2022: 
$1,450,005).

General objectives, policies and processes 
In common with all other businesses, the Group is exposed to risks that arise from its use of financial instruments. This note

Further quantitative information in respect of these risks is presented throughout these financial statements.

Astron Corporation Limited 
Company Number: 1687414 
Notes to the Consolidated Financial Statements 
For the year ended 30 June 2023 
There have been no substantive changes in the Group’s exposure to financial instrument risks, its objectives, policies and 
processes for managing those risks or the methods used to measure them from previous periods unless otherwise stated in 
this note. The principal financial instruments from which financial instrument risk arises are cash at banks, term deposits 
greater than 90 days, trade and other receivables and payables and financial assets at fair value through profit or loss. 
The  Board  has  overall  responsibility  for  the  determination  of  the  Group’s  risk  management  objectives  and  policies.  The 
Groups' risk management policies and objectives are therefore designed to minimise the potential impacts of these risks on 
the results of the Group where such impacts may be material. The Group has significant experience in its principal markets 
which provides the directors with assurance as to the effectiveness of the processes put in place and the appropriateness 
of the objectives and policies it sets. The Group engages a number of external professionals to ensure compliance with best 
practice principles. 
The overall objective of the Board is to set polices that seek to reduce risk as far as possible without unduly affecting the 
Group’s competitiveness and flexibility. Further details regarding these policies are set out below: 
Credit risk 
Credit risk is the risk that the other party to a financial instrument will fail to discharge their obligation resulting in the Group 
incurring  a  financial  loss.  This  usually  occurs  when  debtors  or  counterparties  to  derivative  contracts  fail  to  settle  their 
obligations owing to the Group. 
In  respect  of  cash  investments,  most  of  cash,  cash  equivalents  and  term  deposits  greater  than  90  days  are  held  with 
institutions with an AA- to BBB credit rating. As set out in note 10, a small proportion of the Group’s cash was held with a 
local PRC bank which did not have any credit rating. 
In respect of trade receivables, there is concentration of credit risk as 75% (2022: 22%) of the Group’s trade debtors is from 
two (2022: seven) customers. The increase in concentration risk relates predominantly to the significant decrease in trade 
receivables  during  the  year  ended  30  June  2023.  Group  policy  is  that  sales  are  only  made  to  customers  that  are  credit 
worthy. Trade receivables are predominantly situated in China. 
Other receivables include $1,095,945 (2022: $1,141,839) being the gross land sale receivable from the Yingkou Provincial 
government. The directors are of the opinion that the credit risk on this receivable to be low for the reasons set out in note 11. 
Credit risk is managed on a Group basis and reviewed regularly by management and the Audit & Risk Committee. It arises 
from  exposures  to  customers  as  well  as  through  certain  derivative  financial  instruments  and  deposits  with  financial 
institutions. 
Refer to note 10 for concentration of credit risk for cash and cash equivalents. 
The maximum exposure of the Group to credit risk at the end of the reporting period is as follows: 
Cash & cash equivalents

The Group measures loss allowances for trade receivables at an amount equal to lifetime ECLs, which is calculated using a 
provision matrix. As the Group’s historical credit loss experience does not indicate significantly different loss patterns for 
different customer segments, the loss allowance based on past due status is not further distinguished between the Group’s 
different customer bases. 
The  following  table  presents  the  gross  carrying  amount  and  the  lifetime  expected  credit  loss  in  respect  of  individually

For the year ended 30 June 2023 
The  following  table  presents  the  gross  carrying  amount  under  collective  measurement  (after  individual  assessed  loss

Liquidity risk 
Liquidity risk is the risk that the Group may encounter difficulties raising funds to meet commitments associated with financial 
instruments, e.g. borrowing repayments. The Group manages liquidity risk by monitoring forecast cash flows. As at 30 June 
2023, the Group had cash of $7,204,674 (2022: $2,447,986).

Given that price movements are not considered material to the Group, the Group does not have a risk management policy 
for  price  risk.  However,  the  Group's  management  regularly  review  the  risks  associated  with  fluctuating  input  and  output 
prices. 
As at 30 June 2023, the maximum exposure of price risk to the Group was the financial assets at fair value through profit or 
loss for $8,319 (2022: $7,575). 100% of the Group’s holding is in the mining or energy sector.

security whereby most of the Group’s cash and cash equivalents and term deposits are held with institutions with an AA- to 
BBB credit rating while a proportion is held with an unrated bank in PRC.

The  Group  is  exposed  to  fluctuations  in  foreign  currencies  arising  from  the  sale  and  purchase  of  goods  and  services  in 
currencies  other  than  the  Group's  measurement  currency.  The  Group  manages  this  risk  through  the  offset  of  trade 
receivables and payables where the majority of trading is undertaken in either the USD or RMB. Current trading terms ensure 
that foreign currency risk is reduced by sales terms being cash on delivery where possible.
