About Silex Systems Limited

Forward Looking Statements

(ASX: SLX) (OTCQX: SILXY)

Silex Systems Limited ABN 69 003 372 067 (Silex) is a 
research and development company whose primary asset is 
the SILEX laser enrichment technology, originally developed 
at the Company’s technology facility in Sydney, Australia. 

The SILEX technology has been under development for 
uranium enrichment jointly with US-based exclusive licensee 
Global Laser Enrichment LLC (GLE) for a number of years. 
Success of the SILEX uranium enrichment technology 
development program and the proposed Paducah 
commercial project remain subject to a number of factors 
including the satisfactory completion of the engineering 
scale-up program and uranium market conditions and 
therefore remains subject to associated risks. 

Silex is also in the early stages of pursuing additional 
commercial applications of the SILEX technology, including 
the production of ‘Zero-Spin Silicon’ for the emerging 
technology of silicon-based quantum computing. The ‘Zero-
Spin Silicon’ project remains dependent on the outcomes of 
the project and the viability of silicon quantum computing and 
is therefore subject to various risks. The commercial future of 
the SILEX technology is therefore uncertain and any plans for 
commercial deployment are speculative. 

Additionally, Silex has an interest in a unique semiconductor 
technology known as ‘cREO®’ through its ownership 
of subsidiary Translucent Inc. The cREO® technology 
developed by Translucent has been acquired by IQE Plc 
based in the UK. IQE is progressing the cREO® technology 
towards commercial deployment for 5G mobile handset 
filter applications. The outcome of IQE’s commercialisation 
program is also uncertain and remains subject to various 
technology and market risks.

The commercial potential of these technologies is currently 
unknown. Accordingly, no guarantees as to the future 
performance of these technologies can be made. The 
nature of the statements in this Report regarding the future 
of the SILEX technology, the cREO® technology and any 
associated commercial prospects are forward-looking 
and are subject to a number of variables, including but not 
limited to, unknown risks, contingencies and assumptions 
which may be beyond the control of Silex, its directors and 
management. You should not place reliance on any forward-
looking statements as actual results could be materially 
different from those expressed or implied by such forward 
looking statements as a result of various risk factors. Further, 
the forward-looking statements contained in this Report 
involve subjective judgement and analysis and are subject to 
change due to management’s analysis of Silex’s business, 
changes in industry trends, government policies and any new 
or unforeseen circumstances. The Company’s management 
believes that there are reasonable grounds to make such 
statements as at the date of this Report. Silex does not 
intend, and is not obligated, to update the forward-looking 
statements except to the extent required by law or the ASX 
Listing Rules.

Risk Factors

Risk factors that could affect future results and commercial 
prospects of Silex include, but are not limited to: ongoing 
economic and social uncertainty, including in relation to 
the impacts of the COVID-19 pandemic; the results of 
the SILEX uranium enrichment engineering development 
program; the market demand for natural uranium and 
enriched uranium; the outcome of the project for the 
production of ‘Zero-Spin Silicon’ for the emerging 
technology of silicon-based quantum computing; the 
potential development of, or competition from alternative 
technologies; the potential for third party claims against 
the Company’s ownership of Intellectual Property; 
the potential impact of prevailing laws or government 
regulations or policies in the USA, Australia or elsewhere; 
results from IQE’s commercialisation program and the 
market demand for cREO® products; actions taken by 
the Company’s commercialisation partners that could 
adversely affect the technology development programs;

SILEX ANNUAL REPORT 2021Chair’s Report

Dear Fellow Shareholders,

On behalf of the Silex Board, it is my pleasure to present 
our 2021 Annual Report for Silex Systems Limited. The 
year ended 30 June 2021 has been a pivotal year for 
the Company with the acquisition of our SILEX uranium 
technology licensee, Global Laser Enrichment (GLE) 
in January 2021, and since that time refining GLE’s 
commercialisation strategy. The GLE acquisition was an 
important factor in Silex being able to secure a unique and 
important position in the global uranium and nuclear fuel 
industry through our purchase of a 51% interest in GLE, 
with global uranium and nuclear fuel supplier Cameco 
Corporation increasing its interest from 24% to 49%. On 
behalf of the Board, I would like to thank Cameco for 
their vision, commitment and support for GLE and their 
partnership with Silex.

The SILEX uranium enrichment commercialisation program 
is underpinned by the agreement between GLE and the 
US Department of Energy for the proposed Paducah, 
Kentucky uranium production project. This large, multi-
decade project could enable the SILEX technology 
becoming the ‘go to’ technology for the production 
of nuclear fuel for today’s conventional nuclear power 
reactors and for the next generation Small Modular 
Reactors currently under development.

Through the commercialisation of the SILEX technology, 
your company is building a strong position of commercial 
leverage in several globally relevant growth markets including 
in the uranium and nuclear fuel industry and the emerging 

quantum computing industry. We are also currently 
assessing potential applications in the field of medical 
radioisotopes. We have executed on a number of important 
strategic priorities that uniquely position the Company to 
seize opportunities across these key targets industries in the 
coming years. Our goal is to deliver long-term value to you, 
our shareholders, and to do this with an acute focus on risk 
management and prudent governance.

During the year, the Company has made significant progress 
in the silicon enrichment project being conducted at our 
Lucas Heights facility. Enriched silicon, in the form of Zero-
Spin Silicon (ZS-Si), is a key enabling material for silicon-
based quantum computing. We are currently about half way 
through the three-year project commenced in late 2019, 
in collaboration with world-leading quantum computing 
partners, Silicon Quantum Computing Pty Ltd (SQC) and 
UNSW Sydney. The aim of the project is to establish the 
technology and production capability to produce high purity 
ZS-Si using a variant of the SILEX laser isotope separation 
technology. The project is supported by $1.8 million of 
funding from SQC and a $3 million Federal Government 
funding grant from the Cooperative Research Centre Projects 
(CRC-P). We would also like to thank SQC and UNSW 
Sydney for their expertise, commitment and support of this 
potentially ground-breaking project. 

We continue to be encouraged by the disclosures by UK-
based IQE Plc with respect to the commercialisation of our 
cREO® technology purchased by IQE in 2018. IQE reports 
good progress with its proprietary IQepiMo™ 5G filter device 
technology built on the cREO® platform, which is currently

SILEX ANNUAL REPORT 2021project around the end of 2021, and moving into Stage 3 in 
2022, which will focus on the construction of a commercial 
pilot production facility. Additionally, we will continue our 
assessment of potential value accretive applications of the 
SILEX technology in the field of medical radioisotopes. We 
believe we are well positioned to capitalise on these exciting 
opportunities and build momentum in our commercialisation 
programs over the coming years.

The COVID-19 pandemic continues to create significant 
challenges around the world and particularly for our team 
in the Sydney area. Despite the uncertainties we face, we 
intend to continue with our operations to the fullest extent 
possible, with extreme caution and heightened concern 
for the safety and wellbeing of our team. Our team are 
outstanding and world class in many ways, and we thank 
them for their continued energy and expertise as they strive 
to bring Silex’s vision to fruition. 

My fellow Board members and I, and Silex Management 
thank you for your continued support. I look forward to 
updating you again at our Annual General Meeting in October.

undergoing testing with IQE’s partners and customers. Our 
agreement with IQE includes a minimum 3% royalty on 
revenues derived from use of the cREO® technology. The 
Company received the second minimum annual royalty 
payment from IQE due under this agreement in early 2021.

“Through the commercialisation 
of the SILEX technology, your 
company is building a strong 
position of commercial leverage 
in several globally relevant 
growth markets including in the 
uranium and nuclear fuel industry 
and the emerging quantum 
computing industry”

Corporate Governance 

I am pleased to continue to lead a diverse and high-
quality Board with significant experience in technology 
commercialisation, depth of knowledge in the nuclear 
industry and commitment to strong governance principles. 
The Silex Board currently comprises three non-executive 
directors from a range of professions and backgrounds 
together with our founder and CEO/Managing Director. 
The Board periodically reviews its performance and make-
up to ensure it is serving the needs of the Company, our 
shareholders and other stakeholders. Our governance 
processes are also reviewed annually with a keen focus on 
continual improvement and best practice. 

I will be standing for re-election at this year’s AGM, with the 
support of my fellow Directors, and I never take for granted 
your support as we strive to build further shareholder value. 

The Year Ahead

With the GLE acquisition complete, Silex and Cameco are 
focused on finalising the transition of GLE under the new 
joint venture ownership. We have made some key C-suite 
appointments, Mr Stephen Long as GLE’s Chief Executive 
Officer, and Mr James Dobchuk as GLE’s Chief Commercial 
Officer and President, and we will support them in delivering 
real value for GLE. We also look forward to progressing 
the ZS-Si project towards completion of Stage 2 of the

SILEX ANNUAL REPORT 2021CEO’s Report

Dear Fellow Shareholders, 

FY2021 was a seminal year for Silex with the Company 
achieving significant advances in the commercialisation of 
its SILEX laser enrichment technology. The most important 
event during the year was the successful completion of 
the acquisition of our interest in SILEX uranium enrichment 
technology licensee Global Laser Enrichment LLC (GLE) in 
January 2021. The completion resulted in Silex acquiring a 
51% interest in GLE, and Cameco Corporation increasing its 
interest from 24% to 49%. This acquisition is fundamental 
to the execution of our strategy, to take a leading role in the 
SILEX uranium enrichment technology commercialisation 
program through to GLE’s Paducah ‘Tier 1’ Uranium 
production project.

We also made significant progress during the year on 
commercialising our unique SILEX laser enrichment 
technology for silicon enrichment for silicon-based quantum 
computing with our Zero-Spin Silicon (ZS-Si) project. 

In summary, our key achievements for the year included:

•  Successful completion of the GLE acquisition;

•  Together with Cameco, resetting the technology 

commercialisation plan for GLE and advancing the 
technology development project;

•  Recruitment of a Chief Executive Officer and Chief 

Commercial Officer for GLE;

•  Advancing our ZS-Si project with the achievement of two 

key milestones; and

•  Building the SILEX technology teams in Australia and 

GLE’s team in the US.

SILEX Uranium Production Opportunity

During the past year, there has been increasing attention 
globally on nuclear power as it represents the only economic 
source of zero-emissions, stable base load electricity. The 
ambitious climate commitments being made by countries 
and companies around the world confirms that zero-carbon 
nuclear energy is on an upward trajectory. With significant 
growth forecasted in nuclear power generation around the 
world and the ever-increasing awareness of the adverse 
effects of climate change, we remain encouraged by the 
opportunities emerging for the SILEX technology and GLE in 
the global nuclear fuel industry. 

4

The SILEX technology is being developed in collaboration 
with GLE for the production of natural grade uranium through 
GLE’s flagship Paducah, Kentucky uranium project, with 
additional opportunities evolving for the production of Low 
Enriched Uranium (LEU) for conventional reactor fuel and 
High Assay LEU (HALEU) for the emerging advanced reactor 
and small modular reactor (SMR) technologies.

The Paducah uranium project involves the establishment of 
the proposed Paducah Laser Enrichment Facility (PLEF) to 
commercially deploy the SILEX technology in the US. The 
project is underpinned by the existing agreement between 
GLE and the US Department of Energy for the purchase of 
significant stockpiles of depleted uranium tails, sufficient for 
the production of around 5 million pounds of natural grade 
uranium per year for 30 years.

Preliminary analysis by Silex of the Paducah project 
indicates it could rank equivalent to a ‘Tier 1’ uranium 
resource based on estimates of the long-life and low cost 
of production. GLE and Silex are actively assessing other 
commercial opportunities, including additional capacity at 
the PLEF to produce LEU for conventional nuclear plants 
and HALEU for SMR’s. 

Our focus since completion of the GLE acquisition has been 
on the building of the GLE and Silex teams to complete the 
pilot commercial demonstration program and on securing a 
new executive team for GLE. We have recently announced 
two key leadership appointments for GLE: Stephen Long 
as Chief Executive Officer and James Dobchuk as Chief 
Commercial Officer and President. Both gentlemen are 
seasoned executives and bring a wealth of nuclear industry 
experience to GLE. They are very well placed to lead GLE 
through its commercialisation phase. 

SILEX Zero-Spin Silicon Opportunity

A variant of the SILEX technology has been proven capable of 
producing enriched silicon in the form of Zero-Spin Silicon (ZS-
Si), a key enabling material for the emerging silicon quantum 
computing industry. Our ZS-Si project being conducted 
with project partners Silicon Quantum Computing (SQC) 
and UNSW Sydney aims to scale-up to pilot commercial 
production by the end of CY2022. Successful completion of 
the project will provide Silex with the opportunity to produce 
and sell small commercial quantities of ZS-Si using the pilot 
facility with sufficiently high purity starting from CY2023, and 
to establish the manufacturing technology and capability to 
scale-up production as silicon-based quantum computing 
gains traction globally during the next decade. 

SILEX ANNUAL REPORT 2021Significant progress was achieved during the year in the 
execution of our ZS-Si commercialisation project with the 
completion of two important milestones. In January 2021, 
we announced the completion of a key milestone to validate 
commercial synthesis of feed material for the ZS-Si laser 
enrichment process. We also announced the completion of 
the construction of a scaled-up prototype processing facility 
in May 2021, the third milestone in the ZS-Si project since 
its commencement in December 2019. The facility is in the 
process of being deployed to demonstrate the scalability and 
efficiency of our laser isotope separation (LIS) technology for 
potential commercial production of high-purity ZS-Si. 

These milestones demonstrate significant progress in the 
second stage of the project involving design, construction 
and operation of scaled-up prototype equipment for ZS-
Si. The completion of the prototype processing facility 
represents the first time the technology has been scaled-up 
outside the original uranium enrichment project. Stage 2 of 
the project is due for completion by the end of CY2021.

Current methods for production of enriched silicon are limited 
and costly with only a few kilograms produced annually, 
mostly using gas centrifuge technology. Should the ZS-Si 
project be successful, it could potentially enable Australia 
to establish itself as a world-leader in ZS-Si production. If 
the market for ZS-Si evolves, this could create a new value-
added export market. Importantly, Silex will retain ownership 
of the ZS-Si production technology and related Intellectual 
Property developed through the project.

“The most important event during 
the year was the successful 
completion of the acquisition of 
our interest in SILEX uranium 
enrichment technology licensee 
Global Laser Enrichment LLC 
(GLE) in January 2021.”

SILEX ANNUAL REPORT 2021cREO® Advanced  
Semiconductor Opportunity

In 2018, IQE Plc (AIM: IQE) purchased the cREO® technology 
from Silex. IQE has been responsible for the cREO® 
commercialisation program for a number of years. IQE’s 
purchase of the technology includes a perpetual royalty of at 
least 3% on IQE’s revenues derived from use of the cREO® 
technology, with minimum annual royalties currently being 
paid to Silex annually.

During the year, IQE announced the successful development 
and key demonstration of a new high frequency (RF) filter 
product (called IQepiMo™) which is built on the cREO® 
technology platform. IQE have stated that this new product 
can help eliminate technical issues related to the demands 
that 5G technology places on electronic components, 
including RF filters, which are key to managing high 
frequency signals in 5G devices such as mobile handsets. 
IQE announced in February 2021 that data from customer 
and partner device trials indicated significant improvement 
in the performance of its 5G filter device, compared to 
conventional filter technology, when tested at the top end 
of the frequency range used in current 5G applications. 
Additional trials of the new RF filter product are continuing 
with IQE’s partners. 

Prioritising Health and Safety

Core to our operations and values, is the prioritisation of 
the health and safety of our team. Throughout FY2021, we 
continued to focus on the health, safety and wellbeing of our 
team members across all sites and we reported no lost time 
injuries or reportable incidents. Although full-time operations 
were maintained at the Company’s Lucas Heights facility for 
most of FY2021, consideration of the continuing impact of the 
COVID-19 pandemic and efforts to safely minimise disruptions 
to the Company’s activities is ongoing. Above all else, the 
health, safety and wellbeing of our people is paramount.

I take this opportunity to thank you, our shareholders for 
your ongoing support. I would also like to thank the Silex and 
GLE teams for their dedication and tireless efforts, and to our 
Board for their continued support of the Company’s strategy. 
I am very pleased with the progress we have made over 
the year in both our uranium and silicon projects, and look 
forward to providing a further update at the Annual General 
Meeting in October.

The SILEX Laser Uranium 
Enrichment Technology 

The SILEX technology was invented by 
Silex scientists Dr Michael Goldsworthy 
and Dr Horst Struve in the 1990’s at 

Lucas Heights, Sydney. In order to facilitate the potential 
commercial deployment of the technology in the United 
States, an Agreement for Cooperation between the 
governments of the United States and Australia was signed 
in May 2000. In June 2001, the technology was officially 
Classified by the United States and Australian governments, 
bringing the SILEX technology commercialisation project 
formally under the strict nuclear safeguards, security and 
regulatory protocols of each country.

From 2006 until 2020 the technology commercialisation 
project was managed by GLE as a subsidiary of GE-Hitachi 
Nuclear Energy (GEH) at its nuclear technology complex in 
Wilmington, North Carolina. In 2013, the project passed a 
major milestone with the successful demonstration of the 
technology at prototype scale in a Test Loop facility built by 
GLE – confirming the inherent efficiency of the laser-based 
SILEX technology. From 2014, GEH slowed the pace of 
development in response to the depressed nuclear fuel 
markets in the aftermath of Fukushima.

In December 2019, Silex announced the signing of a binding 
Purchase Agreement between Silex, Cameco Corporation 
(Cameco) and GEH for the purchase of GEH’s 76% interest 
in GLE. Following receipt of US Government approvals, 
this agreement closed in January 2021, resulting in Silex 
acquiring a 51% majority interest in GLE, and Cameco 
increasing its interest from 24% to 49%.

Underpinning GLE’s commercialisation of the SILEX 
technology, is the landmark 2016 agreement with the US 
Department of Energy for the purchase of over 200,000 
metric tons of depleted uranium hexafluoride (UF6), being 
tails material stockpiled from previous decades of enrichment 
operations at the DOE’s gaseous diffusion facility in Paducah, 
which was shut down in 2013. This material will be the 
feedstock for GLE’s Paducah Laser Enrichment Facility 
(PLEF) planned to be operational in the late 2020’s.

Uranium Enrichment

Naturally occurring uranium is dominated by two isotopes, 
U235 and U238. Nuclear energy is produced by the splitting (or 
‘fission’) of the U235 atoms. Natural uranium is made up of 
~0.7% of the ‘active’ U235 isotope with the balance (~99.3%) 
made up of the U238 isotope. Uranium enrichment is the 
process of concentrating or enriching the U235 isotope up to 
approximately 5% for use as fuel in a conventional nuclear 
power reactor. Enrichment is a technically difficult process 
and accounts for around 30% of the cost of nuclear fuel and 
approximately 5% of the total cost of the electricity generated 
by nuclear power.

The Separation of Isotopes by Laser EXcitation (SILEX) 
process is the only third-generation enrichment technology 
at an advanced stage of commercialisation today. It is able 
to effectively enrich uranium through highly selective laser 
excitation of the fluorinated form of uranium – the 235UF6 
isotopic molecule.

The two methods of uranium enrichment used to date are the 
now obsolete Gas Diffusion technique (first generation) and 
Gas Centrifuge (second generation). Silex’s third-generation 
laser-based process provides much higher enrichment 
process efficiency compared to these earlier methods, 
potentially offering significantly lower overall costs.

SILEX ANNUAL REPORT 2021Uranium production and enrichment are the two largest value drivers of the current nuclear fuel cycle, accounting for up to 70% 
of the value of a fuel bundle. 

Furthermore, as the tails feedstock for the PLEF plant is already in the form of UF6, the value of the second step for fuel 
production – conversion – is also captured by the Paducah project.

Key features of the SILEX Uranium Enrichment Technology

The SILEX technology is a unique laser-based process that has the potential to economically separate uranium isotopes (as well 
as commercially valuable isotopes of several other elements). It has a number of advantages over other uranium enrichment 
processes including:

• 

Inherently higher efficiency resulting in lower enrichment costs;

•  Smaller environmental footprint than centrifuge and diffusion plants;

•  Greater flexibility in producing advanced fuels for next generation SMR’s; and

•  Anticipated to have the lowest enrichment plant capital costs.

Nuclear Fuel Production

The SILEX technology, could potentially become a major contributor to nuclear fuel production for the world’s current and future 
nuclear reactor fleet, through the production of uranium in three different forms:

Unat

LEU

HALEU

Natural Grade Uranium (Unat)

Low Enriched Uranium (LEU)

High Assay LEU (HALEU)

via enrichment of DOE 
inventories of depleted tails 
in the Paducah commercial 
project to produce uranium at 
natural U235 assay (~0.7%)

for use as fuel in today’s 
conventional nuclear power 
reactors (includes U235 assays 
between 3% to 5%)

customised fuel for next 
generation SMR’s currently 
under development (includes 
U235 assays up to 19.9%)

The SILEX Uranium Enrichment 
Commercialisation Vehicle: Global Laser 
Enrichment LLC (GLE)

In January 2021, the acquisition of 
SILEX technology licensee GLE, was 
successfully completed, resulting 
in Silex acquiring a 51% interest in GLE, and Cameco 
Corporation, one of the world’s leading uranium and nuclear 
fuel suppliers, increasing its interest from 24% to 49%. 
Completion of the acquisition followed the receipt of US 
Government approval of the transaction. 

GLE’s exclusive worldwide license to commercialise 
the SILEX technology for uranium enrichment is in 
accordance with a Technology Commercialisation and 
License Agreement, amended in 2021. The technology 
commercialisation project is being conducted jointly at GLE’s 
Wilmington, North Carolina facility and at Silex’s Sydney 
facility with the current focus on completion of the full-scale 
demonstration of the SILEX uranium technology utilising a 
pilot plant, being built at GLE’s Test Loop facility.

Silex and Cameco have also negotiated terms for an option 
for Cameco to purchase from Silex at fair market value, an 
additional 26% interest in GLE, potentially increasing their 
interest to 75% (subject to US Government approvals).

This option can be exercised by Cameco from two years 
from completion of the transaction (i.e., from January 2023) 
up until 30 months after the technology is satisfactorily 
demonstrated at full commercial pilot scale (anticipated to be 
in the mid-2020’s).

Paducah Laser Enrichment Facility (PLEF) Project

The path to market for GLE and the SILEX uranium 
enrichment technology is focused on the Paducah Laser 
Enrichment Facility (PLEF) project which has the potential 
to produce around 5 million pounds of uranium annually for 
30 years. Preliminary analysis of the Paducah opportunity 
indicates the project may be equivalent to a ‘Tier 1’ uranium 
project based on the low cost of production and longevity of 
the project.

The PLEF uranium project is underpinned by an agreement 
between GLE and the US Department of Energy for the 
purchase of over 200,000 metric tons of depleted UF6 tails, 
which will be enriched using the SILEX uranium enrichment 
technology to produce natural grade uranium for sale into 
the global uranium market, and then potentially further 
enriched to produce nuclear fuel for zero-emissions electricity 
generation. The PLEF facility is planned to be operational in 
the late 2020’s, depending on market conditions, financing 
and licensing prerequisites.

The SILEX Technology License Agreement

The Technology Commercialisation and License Agreement 
between Silex and GLE is an exclusive worldwide license for 
exploitation of the SILEX technology for uranium enrichment. 
The License Agreement includes royalty revenues and 
milestone payments to Silex as follows (and is independent 
of Silex’s 51% equity interest in GLE and any commercial 
benefits flowing from that interest):

•  Perpetual royalty of a minimum of 7%: payable to 
Silex on GLE’s enrichment SWU1 revenues from use of 
the SILEX technology

•  US$20 million in Milestone Payments: payable to 

Silex triggered by commercial development milestones

1. SWU – Separative Work Unit is the unit of enrichment traded in the market

10

SILEX ANNUAL REPORT 2021A US$15 million milestone payment was also received by 
Silex in July 2013. This was triggered by the successful 
completion of the Test Loop Phase 1 Program Milestone: 
Technology Demonstration and Validation. This milestone 
involved the demonstration of efficient enrichment with the 
SILEX laser technology at the prototype level.

Nuclear power outlook and market update

At the UN’s 2015 Convention on Climate Change (COP21), 
held in Paris, there were pledges made by participating 
countries to limit global warming to well below 2 degrees 
and aiming for 1.5 degrees. The pledges are what is now 
commonly referred to as the Paris Agreement. Under the 
Paris Agreement, countries committed to bring forward 
national plans setting out how much they would reduce their 
emissions and agreed that every five years they would come 
back with an updated plan that would reflect their highest 
possible ambition at that time. There will again be a number 
of important decisions and details to be agreed between the 
participating countries at COP26, to be held in Glasgow in 
November 2021.

In response, there are many countries which have prioritised 
government policy initiatives relating to tackling climate 
change and ensuring energy security, stating that nuclear 
power should form a meaningful part of their energy mix in 
the future.

World Nuclear Reactor Population

443

Nuclear today plays a key role in the supply of carbon-free 
base load electricity and is anticipated to play an increasing 
role in the energy mix as countries around the world strive to 
meet ambitious net zero targets.

According to the World Nuclear Association, there are 
currently 443 operable nuclear reactors globally and 56 
reactors under construction. Today’s operating reactor fleet 
currently generate ~10% of the world’s electricity supply. 

The US is the world’s largest producer of nuclear power with 
93 operable reactors, currently accounting for more than 
30% of worldwide nuclear generation of electricity. Despite 
bold nuclear construction programs in China, India and the 
Middle East, the US is expected to remain the largest nuclear 
power generator for many years to come. There is also 
growing interest and significant investment being made into 
the development of emerging advanced reactor and small 
modular reactor technologies.

With significant growth forecasted in nuclear power generation 
around the world and the ever-increasing awareness of the 
adverse effects of climate change, we remain encouraged by 
the opportunities emerging for the SILEX technology and GLE 
in the global nuclear industry. We believe the SILEX technology 
- the only third-generation laser enrichment technology being 
commercialised in the world today, can help make nuclear 
power a more efficient and cost-effective solution for carbon-
free base load electricity generation.

ZS-Si Production for 
Quantum Computing 

In December 2019, Silex launched a new 
R&D project in conjunction with project 
partners Silicon Quantum Computing Pty 

Ltd (SQC) and UNSW Sydney (UNSW), to develop a process 
for the commercial production of high-purity ‘Zero-Spin 
Silicon’ (ZS-Si) using a variant of the SILEX laser isotope 
separation (LIS) technology.

ZS-Si is a unique form of isotopically enriched silicon required 
for the fabrication of next generation processor chips which 
will power silicon-based quantum computers. Silex’s LIS 
technology has the potential to efficiently produce ZS-Si to 
provide a secure supply of this material for project partner 
and initial customer SQC, in support of its world-leading 
efforts to commercialise silicon-based quantum computing 
technology in conjunction with UNSW.

The three-year ZS-Si project, which was awarded a $3 million 
Federal Government funding grant from the Cooperative 
Research Centre Projects (CRC-P) in February 2020, is due 
for completion at the end of CY2022. The first stage of the 
three-stage project was successfully completed in June 
2020, establishing ‘proof-of-concept’ for the silicon LIS. The 
second stage of the project involves the design, construction 
and operation of scaled-up prototype equipment with the 
objective of verifying the efficiency and scalability of the silicon 
LIS technology and the underlying economics of the process. 

The third stage will culminate with the planned production 
of initial commercial quantities of ZS-Si from a SILEX pilot 
production facility, leading to a full economic assessment of 
the ZS-Si business case.

Silex will retain ownership of the ZS-Si production technology 
and related Intellectual Property developed through the 
project. The first commercial quantities of ZS-Si produced 
from the pilot facility will be purchased by SQC under an 
Offtake Agreement executed in December 2019.

SILEX ANNUAL REPORT 2021Background to Silicon Quantum Computing

Quantum computers are expected to be thousands of 
times more powerful than the most advanced of today’s 
conventional computers, opening new frontiers and 
opportunities in many industries, including medicine, artificial 
intelligence, cybersecurity, global logistics and global 
financial systems. Many countries around the world are 
investing heavily in the development of quantum computing 
technology, with governments and key corporates (such as 
Intel, IBM, Google, Microsoft and others) vying for leadership 
in this emerging strategic industry.

The global quantum computing (QC) opportunity, which 
is anticipated to expand dramatically over the next two 
decades, has recently been forecast by CSIRO Futures to 
be worth around $50 billion in 2040, with an annual growth 
rate of 6%2. A significant proportion of this value will relate 
to hardware, of which silicon-based quantum computers are 
anticipated to play a leading role.

ZS-Si is a key enabling material for the silicon QC processor 
chip. Natural silicon (Si) consists of 3 isotopes: 92.2% 
Si-28, 3.1% Si-30 (each with zero electron spin state) and 
4.7% Si-29 (with a spin state of ½). The presence of Si-
29 in concentrations above 500 parts per million (ppm) 
(0.05%) prevents effective QC performance, so ZS-Si must 
be produced by elimination of the Si-29 isotope. The lower 
the concentration of Si-29, the better a silicon quantum 
processor will perform in terms of computational power, 
accuracy and reliability.

Current methods for production of enriched silicon are limited 
and costly with only a few kilograms produced annually, 
mostly using gas centrifuge technology. Should the ZS-Si 
project be successful, it could potentially enable Australia to 
establish itself as a world-leader in ZS-Si production. If the 
market for ZS-Si evolves, this could create a new value-added 
export market. As the ZS-Si project progresses, Silex will 
engage with other potential customers, possibly including 
some global computer chip manufacturers who are also 
developing silicon quantum computing technology.

SILEX ANNUAL REPORT 2021Other Potential Markets for 
the SILEX Technology

Initially, the Silex team investigated laser 
isotope separation techniques for several 
stable elements, including Chlorine, 

Molybdenum, Carbon, Oxygen and Silicon. Several of these 
stable isotopes already have existing commercial markets 
and production is achieved via traditional methods such 
as cryogenic distillation for carbon and oxygen, and gas 
centrifuge for the others listed above. 

There are emerging markets for isotopes in the medical 
radiopharmaceutical industry, such as Molybdenum and 
Ytterbium. Silex is currently assessing the application of 
the SILEX technology to the enrichment of these valuable 
medical radioisotopes.

The cREO®  
Semiconductor Technology 

Silex subsidiary Translucent Inc developed 
a novel set of semiconductor materials 
known as ‘crystalline Rare Earth Oxides’ 

(cREO®) for application to the manufacturing of advanced 
semiconductor devices (such as wireless and optical 
communications) which use high-performance compound 
semiconductor materials rather than silicon. cREO® is a 
potentially enabling platform technology that could create 
a step-change in the integration of various compound 
semiconductor devices with large scale silicon wafer-based 
production techniques.

The cREO® technology was purchased by UK-based IQE 
in accordance with the 2015 License and Assignment 
Agreement. Under this Agreement, Translucent is currently 
eligible for minimum annual royalties and ultimately, a 
perpetual royalty of at least 3% will be payable to Translucent 
on the sales revenues from any IQE products that utilise the 
cREO® technology. The second minimum royalty payment 
of US$400,000 for the year ended CY2020 was received in 
early 2021.

IQE is the global leader in the design and manufacture of 
advanced semiconductor wafer products used in many 
of today’s advanced semiconductor devices and is a key 
player in the emerging 5G wireless technologies market. IQE 
operates manufacturing facilities in the US, UK and Asia. The 
current focus for the cREO® technology is in the application 
to 5G mobile handset components.

IQE’s Solution – IQepiMo™ based on cREO®

IQE has developed a new high frequency 5G filter product 
(called IQepiMo™) which is built on the cREO® technology 
platform. Following a period of customer and partner device 
trials, IQE announced in February 2021 the achievement of 
a key demonstration milestone for IQepiMo™, disclosing that 
the trials showed significant improvement in the performance 
of its 5G filter device, compared to incumbent technology. 
Additional trials of the new RF filter product are continuing 
with IQE’s partners.

cREO® may also apply to other opportunities beyond 5G 
filters including Power Electronics and these opportunities 
may be explored by IQE at a later date.

4.  Review of operations 

The review contains the following sections:

a)  Operations
b)   Financial Results
c)  Financial Position
d)   Business Strategy and Future Prospects 

a)  Operations

Silex’s operations are currently focused on the development and commercialisation of the SILEX laser isotope separation 
technology for two commercial applications:

i)  Uranium production and enrichment for the production of fuel for the nuclear power industry; and
ii)  Silicon enrichment for the production of ‘Zero-Spin Silicon’ used in the emerging quantum computing industry.

In addition, Silex’s semiconductor material technology known as cREO® was purchased by UK-based IQE Plc in 2018. This 
technology is currently being commercialised by IQE for application in the 5G mobile communications industry under a license 
and royalty agreement signed in 2015. 

SILEX Uranium Enrichment

The development and commercialisation program for the SILEX uranium enrichment technology has been undertaken jointly 
since 2007 by Silex (at its Lucas Heights, Sydney facility) and by GLE (in Wilmington, North Carolina), under an agreement 
originally executed in 2006 (and as amended in 2021). GLE is the exclusive Licensee of the SILEX uranium enrichment 
technology. The GLE acquisition was completed on 31 January 2021 following conclusion of a US Government approval 
process and resulted in Silex acquiring a 51% interest in GLE and Cameco increasing its interest from 24% to 49%. The terms 
of the GLE restructure were in accordance with a binding Membership Interest Purchase Agreement (MIPA) between Silex, 
Cameco Corporation (Cameco) and GE-Hitachi Nuclear Energy (GEH) that was executed in December 2019 for the joint 
purchase of GEH’s 76% interest in GLE. 

The MIPA included a number of key financial terms and provisions including the Purchasers’ obligation to reimburse GEH for 
their respective share of funding for GLE’s Wilmington activities up until closing. Silex reimbursed GEH US$170,000 per month 
from 1 January 2020 through to 31 January 2021, representing 51% of GLE’s funding, with the balance (49%) being contributed 
by Cameco. Following closing of the MIPA, Silex and Cameco have been responsible for the ongoing funding of GLE (in the ratio 
of 51:49 respectively). 

Silex and Cameco have also negotiated terms for an option for Cameco to purchase from Silex at fair market value, an additional 
26% interest in GLE, potentially increasing their interest to 75% (subject to US Government approvals). This option can be 
exercised by Cameco from two years from completion of the transaction (i.e., from 31 January 2023) up until the date 30 
months after the technology is satisfactorily demonstrated at full commercial pilot scale (anticipated to be in the mid-2020’s).

The GLE acquisition also included a site lease between GLE and GEH enabling GLE to complete the SILEX technology 
commercialisation program at the Test Loop facility in Wilmington, North Carolina. This program will culminate with the full-scale 
demonstration of the SILEX uranium enrichment technology with a pilot plant facility, currently being built at the Wilmington site. 

In parallel with the GLE restructure activities, a focused operational effort has continued on the technology commercialisation 
program at both the Silex, Sydney and GLE, Wilmington project sites. Laser system development activities in Sydney include 
design upgrades and optimisation for the prototype commercial-scale laser system. Activities in Wilmington include the scaling 
up of enrichment process equipment and preparation of the Test Loop facility for future deployment of prototype production 
equipment required for pre-commercial uranium enrichment testing.

SILEX ANNUAL REPORT 2021Directors’ Report

Zero-Spin Silicon for Quantum Computing

In December 2019 Silex launched a new R&D project in conjunction with project partners SQC and UNSW, to develop 
a process for the commercial production of high-purity ZS-Si using a variant of the SILEX laser isotope separation (LIS) 
technology. ZS-Si is a unique form of isotopically enriched silicon required for the fabrication of next generation processor 
chips which will power silicon-based quantum computers. Silex’s LIS technology has the potential to efficiently produce ZS-Si 
to provide a secure supply of this material for initial customer SQC, in support of its world-leading efforts to commercialise 
silicon-based quantum computing technology in conjunction with UNSW.

The three-year ZS-Si project, which was awarded a $3 million Federal Government funding grant from the Cooperative 
Research Centres Projects (CRC-P) in February 2020, is due for completion at the end of CY2022. 

The first commercial quantities of ZS-Si may potentially be produced from the Silex pilot facility from CY2023, and will be 
purchased by SQC under an Offtake Agreement executed in December 2019. The Offtake Agreement includes SQC making 
three annual payments of $300,000 as an offset against future purchases of ZS-Si produced by Silex. The second $300,000 
payment was received in December 2020, with the final $300,000 payment due in December 2021. 

cREO® Technology

The cREO® technology was purchased by UK-based IQE Plc (AIM: IQE) in early 2018 in accordance with a 2015 License 
and Assignment Agreement. As a result, payment of US$5 million was received by Silex in September 2018 (in IQE stock). 
Minimum annual royalties have been payable by IQE since CY2019 with the CY2020 minimum royalty of US$400,000 being 
received in February 2021. Minimum annual royalties are anticipated to continue until the earlier of completion of IQE’s cREO® 
commercialisation program or CY2024. In addition, a perpetual revenue royalty of at least 3% will be payable to Silex on the sale 
of any IQE products that utilise the cREO® technology.

COVID-19 Implications

The developments and implications associated with the COVID-19 global pandemic continue to be constantly monitored. COVID 
has created significant uncertainty and challenges across the world and our priority remains to ensure we conduct our operations 
with extreme caution and concern for the safety and wellbeing of our team. Our operations have continued under our COVID 
management plan which is in line with Government requirements and recommendations. Our plan remains under constant review 
and is expected to be a core part of our operations for some time. Our current response includes the following actions:

•  Constant monitoring of safety and hygiene protocols

•  All meetings held virtually 

•  The restriction of all non-essential visitors and contractors to our facility

•  Supporting corporate staff to work from home

•  Suspension of all business travel until further notice

•  Supporting staff to obtain their vaccinations as soon as possible

The Company received $154,500 from the Federal Government’s JobKeeper program for the year ended 30 June 2021 
($66,000 was received for the year ended 30 June 2020). The Company also received $50,000 during the year ended 30 June 
2021 from the Federal Government’s Temporary Cash Boost for Employers ($50,000 received for the year ended 30 June 2020).

The net loss from ordinary activities was $6.9m compared to $7.8m in the prior year. The decrease in net loss from ordinary 
activities is mainly due to a $1.1m increase in Revenue from continuing operations. Following the completion of the acquisition 
of GLE on 31 January 2021, Silex recommenced being reimbursed by GLE for its costs on the uranium project. Recoverable 
project costs were $1.3m for the five months ended 30 June 2021. Silex’s obligation to reimburse GEH for our share of funding 
for GLE’s Wilmington activities ceased at closing. The Development expenditure up to 31 January 2021 was $1.6m compared to 
$4.5m in the prior year. The prior year included a holdback amount of US$1.125m paid to GEH for the reimbursement of costs 
held over from the previous Term Sheet (which became payable on the signing of the MIPA). 

From closing, Silex’s 51% share of GLE’s net loss from is recognised in Share of net loss of associates and joint ventures 
accounted for using the equity method and was $2.1m for the current period. 

Employee benefits expense and Research and development materials were also higher in the current year, with increases of 
$0.9m and $0.3m respectively to the prior period, as our headcount and project activities increased. 

Further commentary on the results from our operations and the factors contributing to the decreased net loss from ordinary 
activities (after tax) attributable to members is provided below. 

Silex Systems 

The loss generated by Silex Systems was $3.8m in the current and prior year. The increase in Recoverable project costs revenue 
of $1.3m was offset by an increase in expenses (mainly Employee benefits expense and Research and development materials). 

Translucent

The Translucent segment result was a $0.7m profit in the current year compared to a profit of $0.6m the prior year. The current 
year result included $0.7m Royalty revenue from the sale of intellectual property which related to the accrual of royalties in 
accordance with the sale of the cREO® technology to IQE Plc compared to $0.6m in the prior year.

Silex USA

The Silex USA segment result was a loss of $3.8m compared to a loss of $4.6m in the prior year. The prior year included a 
holdback amount of US$1.125m paid to GEH for the reimbursement of GLE costs held over from the previous Term Sheet.

and Financial assets at fair value through Other comprehensive income of $5.8m (shares in IQE). The reduction in net assets 
of $5.4m was mainly due to the net loss for the year and was partly offset by the disposal of 2.8 million IQE shares (at a gain 
compared to the 30 June 2020 value).

d)  Business Strategy and Future Prospects

Silex’s Strategy

Silex is a platform technology company, focused on the commercialisation of our innovative SILEX laser isotope separation 
technology across multiple markets. The execution of our strategy is through the following activities:

•  Taking a leading role in the SILEX uranium enrichment technology commercialisation program through our ownership of a 51% 

interest in exclusive Licensee GLE;

•  Building our path to market in the US through the Paducah uranium production opportunity, which is underpinned by GLE’s 

agreement with the US Department of Energy (DOE);

•  Developing the SILEX technology for the production of enriched silicon in the form of Zero-Spin Silicon – a key material 

required for quantum computer chip fabrication; and

•  Undertaking an assessment of additional potential applications of the SILEX technology in fields such as medical radioisotopes.

20

SILEX ANNUAL REPORT 2021Directors’ Report

SILEX Uranium Enrichment 

The SILEX technology is the only known third-generation laser-based uranium enrichment technology under commercial 
development today. Subject to the successful completion of the commercialisation project, market conditions and other factors, 
the SILEX technology could become a major contributor to nuclear fuel production for the world’s current and future nuclear 
reactor fleet, through the production of uranium in three different forms: 

•  Natural Grade Uranium (Unat): via re-enrichment of DOE inventories of depleted tails through the Paducah Laser Enrichment 

Facility (PLEF) project - producing uranium at natural U235 assay of ~0.7%; 

•  Low Enriched Uranium (LEU): for use as fuel in today’s conventional nuclear power reactors – which require fuel with U235 

assays of between 3% to 5%; and 

•  High Assay LEU (HALEU): a customised fuel for next generation Small Modular Reactors (SMRs) currently under 

development - several of which require fuel with U235 assays of between 5% and 19.9%.

Uranium production and enrichment are the two largest value drivers of the nuclear fuel cycle, accounting for up to 70% of 
the value of a fuel bundle at current market prices. Commercialisation of the SILEX uranium enrichment technology through 
Licensee GLE may enable the SILEX technology to become a unique, multi-purpose nuclear fuel production platform for existing 
and emerging nuclear power generation systems, including as a potential producer of HALEU. 

Status of Nuclear Fuel Markets

There is significant growth forecasted in nuclear power generation around the world. There are many countries which have 
prioritised government policy initiatives relating to tackling climate change and ensuring energy security, stating that nuclear power 
should form a meaningful part of their energy mix in the future. According to the World Nuclear Association, there are currently 
443 operating nuclear reactors globally and 56 reactors under construction. Today’s operating reactor fleet currently generate 
~10% of the world’s electricity supply. Nuclear today plays a key role in the supply of carbon-free base load electricity and is 
anticipated to play an increasing role in the energy mix as countries around the world strive to meet ambitious net zero targets. 

The US is the world’s largest producer of nuclear power with 93 operable reactors, currently accounting for more than 30% of 
worldwide nuclear generation of electricity. Despite bold nuclear construction programs in China, India and the Middle East, 
the US is expected to remain the largest nuclear power generator for many years to come. There is also growing interest and 
significant investment being made into the development of emerging advanced reactor and small modular reactor technologies.

The outlook in the markets for nuclear fuel continue to improve with increasing concerns regarding security of supply over the 
longer term. The uranium spot price is currently ~US$33/lb, having increased in recent years from a low of US$18/lb. The term 
price of enrichment has also improved significantly in recent years and increased more than 15% to ~US$60/SWU in the last 12 
months. The improvements in the prices of the various components of nuclear fuel reflect the recent filling of the demand gap 
that resulted from the forced and premature nuclear reactor shutdowns that have occurred since Fukushima in March 2011. With 
respect to uranium production, there has also been reductions to primary production in recent years, including disruptions in 
response to COVID-19 that continue to bear on the market.

With the ever-increasing awareness of the adverse effects of climate change, we remain encouraged by the opportunities 
emerging for the SILEX technology and GLE in the global nuclear industry. We believe the SILEX technology - the only third 
generation laser enrichment technology being commercialised in the world today, can help make nuclear power a more efficient 
and cost-effective solution for carbon-free base load electricity generation.

SILEX ANNUAL REPORT 2021Directors’ Report

The Paducah ‘Tier 1’ Uranium Production Project 

The Paducah commercial project opportunity is an ideal path to market for the SILEX technology and GLE. Underpinning this 
opportunity is the Sales Agreement between GLE and the US Department of Energy (DOE) which provides GLE access to large 
stockpiles of depleted uranium tails inventories owned by the DOE. 

The Paducah commercial project opportunity will involve GLE constructing the proposed ‘Paducah Laser Enrichment Facility’ 
(PLEF) utilising the SILEX technology to enrich the DOE tails inventories which have been stored in the form of depleted uranium 
hexafluoride (UF6 - containing U235 assays of between 0.25% to 0.4%) to produce natural grade uranium (assay of ~0.71%). 
Subject to completion of the technology commercialisation project, regulatory approvals, financing and prevailing market 
conditions, it is anticipated the PLEF will commence commercial operations from the late 2020’s.

Production of natural grade uranium at the PLEF would continue over three decades, with the output sold into the global uranium 
market at a production rate equivalent to a uranium mine producing an annual output of around 5 million pounds of uranium 
oxide, which would rank in the top ten of today’s uranium mines by production volume. Preliminary analysis by Silex of the PLEF 
project indicates it could rank as a ‘Tier 1’ uranium resource based on estimates of the long-life and low cost of production.

SILEX Technology License Agreement with GLE

The Technology Commercialisation and License Agreement between Silex and GLE is an exclusive worldwide license for 
exploitation of the SILEX technology for uranium enrichment. The License Agreement is independent of Silex’s 51% equity 
interest in GLE and any commercial benefits flowing from that equity interest. The License Agreement includes royalty revenues 
and milestone payments to Silex as follows:

•  Perpetual royalty of a minimum of 7% - on GLE’s enrichment SWU revenues from use of the SILEX technology

•  US$20 million in Milestone Payments - payable to Silex triggered by commercial development milestones

A US$15 million milestone payment was also received by Silex in July 2013. This was triggered by the successful completion of 
the Test Loop Phase 1 Program Milestone: Technology Demonstration and Validation. This milestone involved the demonstration 
of efficient enrichment with the SILEX laser technology at the prototype level.

In light of the current market conditions, the receipt of potential additional milestone payments and royalties remains uncertain.

The Company continues to take a cautious approach to the SILEX technology commercialisation program in line with current 
market conditions. Ultimately, the future of the technology and likelihood of success in the remaining commercialisation program 
is dependent on a recovery in the global markets for natural and enriched uranium. Commercialisation of the SILEX uranium 
enrichment technology therefore remains subject to these and other risks.

Zero-Spin Silicon for Quantum Computing

Silex’s LIS technology has the potential to efficiently produce ZS-Si to provide a secure supply of this material for initial customer 
and project partner SQC, in support of its world-leading efforts to commercialise silicon-based quantum computing technology 
in conjunction with UNSW.

Quantum computers are expected to be thousands of times more powerful than the most advanced of today’s conventional 
computers, opening new frontiers and opportunities in many industries, including medicine, artificial intelligence, cybersecurity 
and global financial systems. Many countries around the world are investing heavily in the development of quantum computing 
technology, with governments and key corporates (such as Intel, IBM, Google, Microsoft and others) vying for leadership in this 
emerging strategic industry. 

The first stage of the three-stage project was successfully completed in June 2020, establishing ‘proof-of-concept’ for the 
silicon LIS process identified by Silex. The second stage of the project is scheduled for completion at the end of CY2021. The 
second stage involves the design, construction and operation of a scaled-up prototype demonstration facility with the objective 
of verifying the efficiency and scalability of the silicon LIS technology and the underlying economic limit of the process (in terms 
of achievable isotopic purity). The design and construction of the facility was completed in May 2021 and the second stage 
operation and testing program remains on track to be completed by the end of CY2021.

The third stage, scheduled to be completed in CY2022, will culminate with the planned production of initial commercial quantities 
of ZS-Si from a SILEX pilot production facility, leading to a full techno-economic assessment of the ZS-Si business case. 

Following pilot production and the full economic assessment of the ZS-Si business case, the Company may proceed with the 
construction of a SILEX commercial ZS-Si production plant at Silex’s Lucas Heights facility. The ZS-Si project remains dependent 
on the outcomes of the project and the viability of silicon quantum computing and is therefore at risk.

cREO® Technology

The commercial prospects of the cREO® technology remain positive with IQE continuing to pursue the development of the 
technology for their unique high frequency (RF) filter product (called IQepiMo™) for 5G mobile handset applications. IQE is the 
global leader in the design and manufacture of advanced semiconductor wafer products used in many of today’s advanced 
semiconductor devices and is a key player in the emerging 5G wireless technologies market. 

In November 2020, IQE announced the successful development of their IQepiMo™ product which is built on the cREO® template 
technology. Following several months of customer and partner device trials, IQE announced in February 2021 the achievement 
of a key demonstration milestone for IQepiMo™ with significant improvement in the performance of its 5G filter device measured 
at the high-end frequency range, compared to incumbent technology. This represents encouraging progress towards managing 
high frequency signals in 5G devices such as mobile handsets. 

Minimum annual royalties have been payable by IQE since CY2019 with the CY2020 minimum royalty of US$400,000 being 
received in February 2021. In addition, a perpetual revenue royalty of at least 3% will be payable to Silex on the sale of any IQE 
products that utilise the cREO® technology.

The outcome of the cREO® commercialisation program being conducted by IQE remains subject to various technology and 
market risks.

6.  Significant changes in state of affairs

On 31 January 2021, closing of the Agreement between Silex, Cameco and GEH for the joint purchase of GEH’s 76% interest 
in GLE occurred. As a result, Silex acquired a 51% interest in GLE and Cameco increased its interest from 24% to 49%. Several 
other agreements and documents were executed and closed simultaneously, including a site lease to enable the continuance of 
GLE’s operations at its Test Loop facility in Wilmington, North Carolina. The Agreement provides for deferred annual purchase 
payments to GEH totalling US$20 million consisting of four annual payments of US$5 million (shared pro-rata by Silex and 
Cameco) triggered after the first year GLE generates US$50 million in revenues. Various contractual arrangements have also 
been made with GLE partner Cameco, including an option for Cameco to potentially acquire a further 26% equity in GLE from 
Silex at fair market value.

Silex’s 51% interest in GLE is accounted for as a joint venture which is further outlined in note 6 to these financial statements. 
Furthermore, as a result of closing of the Agreement, the contingent liability disclosed in the prior year financial report has 
been extinguished.

During the year, Silex disposed of 30% of its holding in IQE shares with net proceeds of $3.9m (US$3.0m) received. The disposal 
of the shares has been recognised in these financial statements.

7.  Matters subsequent to the end of the financial year

There continues to be significant uncertainty associated with the potential impacts of the COVID-19 pandemic. Although full-
time operations were maintained at the Company’s Lucas Heights facility during FY2021, the Company continues to review the 
evolving COVID-19 situation with a view to making additional changes to operations if needed and/or if advised by the NSW 
Government. Consideration of the prolonged impact of the pandemic and efforts to safely minimise disruption to the Company’s 
activities is ongoing.

The consolidated entity is not aware of any other matters or circumstances which are not otherwise dealt with in the financial 
statements that have significantly, or may significantly, affect the operations of the consolidated entity, the results of its 
operations or the state of the consolidated entity in subsequent years other than those referred to in this Directors’ Report.

10.  Remuneration Report 

On behalf of the People & Remuneration Committee and the Board, I am pleased to present to you the FY2021 Silex Systems 
Limited Remuneration Report, for which we seek your support at our Annual General Meeting (AGM) in October 2021. The 
details of the remuneration received by the Company’s Key Management Personnel (KMP) are prepared in accordance with 
accounting standards, legislative requirements and best practice corporate governance guidance.

The Company’s People & Remuneration Committee oversees remuneration strategy, policy and framework, and executive KMP 
remuneration. The Committee evaluates the Company’s strategy and objectives and makes remuneration recommendations to the 
Board which include focused performance measures for executive KMP. Our remuneration strategy has the following objectives:

•  attract, motivate and retain highly qualified and specialised personnel;

•  alignment of remuneration outcomes with the successful delivery of the Company’s strategy; 

•  align the interests of our directors and executive KMP with Silex’s shareholders and other stakeholders; and

•  ensure competitive, reasonable and transparent renumeration outcomes.

The Company executed on a number of important strategic priorities in FY2021, most notably, the acquisition of GLE following 
the receipt of US Government approvals. In response to the closing of the GLE acquisition, our successful early transition of GLE 
to new ownership and the pleasing progress to date with regard to our ZS-Si project, we took the opportunity during the year 
to review the Company’s executive incentive programs to align future rewards with the achievement of both our short-term and 
long-term strategic objectives. 

As a result, a multi-year incentive program was developed and we intend to continue to offer short-term and long-term 
incentives using a variety of equity-based awards rather than cash. The Committee and the Board believe the new multi-year 
incentive program is both modest and appropriate given the significance of the potential achievement of the targets on the long-
term value for shareholders, and we recommend it to shareholders for approval. 

It was also once again resolved that no increases be awarded with respect to base remuneration for FY2021 or FY2022 for our 
CEO/MD and CFO/Company Secretary, with the Committee recommending that remuneration be more heavily weighted to 
incentive opportunities. During the year, we introduced an annual fee associated with the additional governance responsibilities with 
regard to Chairing the GLE Governing Board. The additional fee is payable using both Silex equity (subject to shareholder approval 
at the 2021 AGM) and cash. All other Board and Committee fees remain unchanged since the last Remuneration Report.

Details of the remuneration outcomes for FY2021, reflecting the achievements during the year and the new multi-year 
remuneration arrangements for our executives are provided in this report. Equity-based incentives for our CEO/MD with respect 
to FY2021, which are detailed in this report, remain subject to shareholder approval and will be detailed in the Notice of Meeting 
for our 2021 AGM.

The Committee and the Board believe equity-based compensation is important to conserve cash reserves as much as possible 
and to motivate employees to align their interests with those of our shareholders to drive positive outcomes in the longer 
term. Our Employee Incentive Plan (EIP), that was reintroduced for employees in May 2019, is an important component of 
our remuneration structure to drive performance and to incentivise retention. We are pleased that staff have welcomed the 
opportunity to receive equity-based compensation. The EIP allows us to use a variety of equity awards, vesting criteria, eligibility 
and tailored key performance indicators as may be appropriate from time to time. 

We continuously monitor market developments and best practice recommendations with respect to compensation to ensure our 
decisions are appropriate in relation to the Company’s performance and to enable adjustment of our remuneration structure and 
practices as required.

We invite you to review the full Remuneration Report and we look forward to answering any questions you may have at our AGM 
in October 2021.

Craig Roy 
Chair, People & Remuneration Committee

People & Remuneration Committee structure

The People & Remuneration Committee is a committee of the Board comprised of a majority of independent non-executive 
directors. The Chair of the Committee is also an independent non-executive director. Its role is to make recommendations to 
the Board regarding the Company’s remuneration policies and practices, including those applicable to the Company’s KMP. 
Members of the People & Remuneration Committee as at the 30 June 2021 were as follows:

Committee members

Other individuals who regularly attended meetings

Dr M P Goldsworthy | CEO/MD

The role of the People & Remuneration Committee is to: 

•  Review and recommend to the Board appropriate remuneration policies and practices that are competitive and reasonable for 
the Company relative to its performance, and to make specific recommendations in relation to KMP compensation, as well as 
the general application to all employees;

•  Determine and recommend remuneration levels of the CEO/MD and CFO/Company Secretary for Board approval; 

•  Manage the incentive plans which apply to executive KMP, including key performance indicators and performance hurdles; and

•  Review and make recommendations to the Board regarding the remuneration of non-executive directors.

The role and responsibilities of the People & Remuneration Committee are set out in the People & Remuneration Committee 
Charter, which is available on the Company’s website at: https://www.silex.com.au/corporate/corporate-governance/. 

The Company did not engage remuneration consultants during FY2021. The Company accesses market data and industry 
remuneration surveys and reports on a regular basis. 

c)  Linking remuneration structure to Company performance

Remuneration strategy, policy and framework

In determining executive KMP remuneration, the Board’s policy is based on the principle of aligning remuneration outcomes 
with the successful delivery of strategy whilst ensuring our remuneration practices are designed to attract, motivate and retain 
highly qualified and specialised personnel. High regard for contemporary market practice, good governance and alignment to 
changing business circumstances is maintained at all times. The Company aims to reward executive KMP with a level and mix of 
remuneration commensurate with their position and responsibilities within the Company that is competitive within the market. 

Remuneration for executive KMP is reviewed annually and considers market data, insights into remuneration trends, the 
performance of the Company and the individual, and the broader economic and operating environment. 

Following the closing of the GLE acquisition and the pleasing progress to date with regard to our ZS-Si project, we conducted 
a review of the Company’s executive KMP incentive programs during the year to align future rewards with the achievement of 
our strategic objectives. A multi-year incentive program was developed, involving the issue of Short-term incentives (STIs) and 
Long-term incentives (LTIs) using a variety of equity-based awards and therefore aligned with the creation of shareholder value 
over the long-term. With regard to our CEO/MD, the Board resolved to introduce the new LTI structure for FY2021 (subject to 
shareholder approval).

The executive KMP remuneration framework will comprise two components:

•  Total fixed remuneration; and 

•  At-risk incentives.

SILEX ANNUAL REPORT 2021Directors’ Report

TFR is comprised of base salary and superannuation. TFR is reviewed annually, or on promotion. It is benchmarked against 
market data for comparable roles in companies in a similar industry and with similar market capitalisation. The Committee 
aims to position executives at or near the median, with flexibility to take into account capability, experience, and value to the 
organisation and performance of the individual. 

A multi-year equity-based incentive program has been developed, involving the issue of Short-term incentives (STIs) and Long-
term incentives (LTIs). Annual incentives have been set through to FY2024 for the CFO and FY2025 for the CEO, in order to drive 
performance and talent retention. STIs have a 12-month performance period and LTIs are assessed over a three-year period 
and are designed to promote long-term stability in share price appreciation. The CEO’s potential Extended LTI has performance 
criteria specifically tailored to outcomes relating to the scale-up of the unique SILEX uranium enrichment technology and 
will be assessed over a performance period ending 31 December 2025. Achievement of the Extended LTI will be subject to 
independent verification. 

Assessing performance and claw-back of remuneration

The People & Remuneration Committee is responsible for assessing performance against KPIs and determining the incentive 
awards to be paid to all senior management. To assist in this assessment, the Committee receives detailed reports on 
performance from Management which are based on independently verifiable data such as financial measures, market 
information and data from independently run surveys. At all times, the Board has the discretion to make a final determination. 

In the unlikely event of serious misconduct or a material misstatement in the Company’s financial statements the Board can 
cancel or defer performance-based remuneration and may also claw back performance-based remuneration paid in previous 
financial years.

d)  Voting at the Company’s 2020 Annual General Meeting

Silex Systems Limited received more than 99% of “yes” votes on its Remuneration Report for the 2020 financial year.

Exercise price

Subject to shareholder approval, the proposed LTI 
is intended to be a multi-year incentive equivalent to 
an annual grant of 150,000 options for the 5 years 
ending 30 June 2025. 

Issue of 750,000 options (i.e., 150,000 options 
attributable to each year from FY2021 to FY2025)

The equity-based LTI will have vesting periods 
that end from 30 June 2024 to 30 June 2028. The 
equity-based LTI grant is subject to shareholder 
approval at the AGM. In the event shareholder 
approval is received for the LTI grant, and the 
options are eligible to be exercised, any resulting 
allotment of Silex Systems Limited shares will be 
subject to a further escrow period of 2 years. 

Should shareholder approval be received for the above 
grant of options, the options’ exercise price will be 
$0.94. This exercise price was determined based 
on the volume weighted average price at which the 
Company’s shares were traded on the Australian Stock 
Exchange for the 10-trading days up to and including 
24 June 2021.

An equity-based LTI may be granted annually at 
the discretion of the Board. For FY2021, the LTI 
comprised a grant of options.

Issue of 200,000 options

The annual equity-based LTI has a 3-year vesting 
period. Any resulting allotment of Silex Systems 
Limited shares on completion of the underlying 
service-condition and option exercise, will be subject 
to a further escrow period of 2 years.

The options’ exercise price is determined based 
on the volume weighted average price at which 
the Company’s shares are traded on the Australian 
Stock Exchange for the 10-trading days preceding 
the grant date. For the March 2021 issue of options, 
the exercise price is $1.20.

SILEX ANNUAL REPORT 2021Directors’ Report

f)  Link between FY2021 remuneration and performance 

FY2021 performance and impact on remuneration

The Company’s performance during FY2021 was considered strong, with delivery on a number of strategic priorities, including 
closing of the GLE acquisition following the receipt of US Government approvals and significant milestones achieved for the 
Zero-Spin Silicon project. For further information on the Company’s performance during the year, refer to the Operating and 
Financial Review in Section 4 of this Directors’ Report. 

As a result of these positive achievements, the Board awarded the CEO/MD 77% of the FY2021 performance rights and the 
CFO/Company Secretary 83% of the FY2021 performance rights (subject to completion of the service-condition ending 31 
July 2021). The Board also resolved to implement multi-year equity-based incentives for the CEO/MD from FY2021 (subject to 
shareholder approval) and the CFO/Company Secretary from FY2022. The incentive design is intended to retain executive KMP 
and to provide longer term benefits if key service and performance conditions are met together with sustained appreciation in 
shareholder value.

Statutory performance indicators

We aim to align executive KMP remuneration to our strategic and business objectives and the creation of shareholder 
wealth. The below table shows measures of the Company’s financial performance over the last five years as required by the 
Corporations Act 2001. However, as a pre-revenue company, the below measures are generally not the measures used in 
determining the variable amounts of remuneration to be awarded to KMPs. As a consequence, there is only a partial correlation 
between the statutory key performance measures and the variable remuneration awarded.

SILEX ANNUAL REPORT 2021Directors’ Report

h)  Non-executive directors remuneration arrangements

Non-executive directors receive a directors’ fee and a fee for chairing or participating on Board committees. They do not receive 
performance-based pay or retirement allowances. The fees are exclusive of superannuation and are reviewed annually taking 
into account comparable roles and market data. The standard Board and Committee fees have not changed since the last 
Remuneration Report. 

Following the closing of the GLE acquisition in January 2021, a new Governing Board for the restructured GLE was established, 
which comprises two members each from Silex and Cameco. The Silex members are the Silex CEO/MD and the Silex 
Board Chair, who will also Chair the GLE Governing Board through to 31 December 2023. In view of the extra work load and 
responsibility associated with the role of Chair of the new Governing Board, an additional $40,000 per annum will be paid to the 
Chair from 1 January 2021. It is proposed that $20,000 of the fees be paid in cash, with the balance, $20,000 proposed to be 
paid by the issue of Silex shares (as announced to the ASX on 25 February 2021 in the Company's Operational Update). 

Subject to shareholder approval at the 2021 AGM, 84,507 shares, at a deemed price of $0.71, are to be issued in lieu of a 
cash payment of $60,000, being 50% of the Directors' fees payable for the 3-year term of the appointment as Chair of the 
GLE Governing Board. The deemed price of $0.71 is based on the 10-trading day volume weighted average price at which the 
Company's shares traded on the Australian Stock Exchange preceding 17 December 2020. 

Additional fees may be payable to non-executive directors should they undertake specific consulting projects for the Company in 
the areas of their expertise. No additional fees were paid for additional services and consulting rendered during FY2021.

The maximum annual aggregate directors’ fee pool limit is $750,000 and was approved by shareholders at the 2011 AGM. 

The current annual fee structure is outlined below:

k)  Terms and conditions of the equity-based payment arrangements

STI – Performance Rights

Commencing for FY2021, an annual STI in the form of Performance Rights is to be issued to executive KMP. The rights vest at the 
end of a 12-month performance period subject to the achievement of individually tailored KPIs. Each right that vests is converted 
into one ordinary share. The rights carry no dividend or voting rights. 

The fair value of the rights is determined based on the market price of the Company’s shares at the grant date or for those 
rights which are subject to a market condition, with reference to a Monte Carlo simulation taking into account the volatility of the 
Company’s shares and other factors.

LTI – Options

The number of options over ordinary shares in the Company provided as remuneration to executive KMP is shown below. The options carry no 
dividend or voting rights. The options are subject to a service-based condition which must be satisfied for the options to vest.

When exercisable, each option is convertible into one ordinary share of Silex Systems Limited. The exercise price of options is based on the 
volume weighted average price at which the Company's shares are traded on the Australian Stock Exchange for the 10-trading days before the 
options are granted or for the 10-trading days preceding a Board resolution to grant options. There were no vested options as at 30 June 2021 
and therefore no options exercised in FY2021 (or FY2020).

The potential grant of options to our CEO/MD for the FY2021 LTI is subject to shareholder approval at the 2021 AGM. If granted, details will be 
provided to the ASX and included in the Remuneration Report for the year ending 30 June 2022.

The Company has entered into Deeds to indemnify the directors of the Company against all liabilities to persons (other than the 
Company or related body corporate) which arise out of the performance of their normal duties as directors or executive officers 
unless the liability relates to conduct involving lack of good faith. The Company has agreed to indemnify the directors and 
executive officers against all costs and expenses incurred in defending an action that falls within the scope of the indemnity.

The Directors’ & Officers’ Liability Insurance provides cover against all costs and expenses involved in defending legal actions 
and any resulting payments arising from a liability to persons (other than the Company) incurred in their position as a director or

15. Non-audit services

The Company may decide to employ the auditor on assignments additional to their statutory audit duties where the auditor’s 
expertise and experience with the Company and/or the consolidated entity are important.

Details of the amounts paid or payable to the auditor (PricewaterhouseCoopers) for non-audit services provided during the year 
are set out below. 

The Board of Directors has considered the position and, in accordance with the advice received from the Audit Committee, 
is satisfied that the provision of the non-audit services 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 below, did not compromise the auditor independence requirements of the Corporations Act 2001 for the following reasons:

•  all non-audit services have been reviewed by the Audit Committee to ensure they do not impact the impartiality and objectivity 

of the auditor

•  none of the services undermine the general principles relating to auditor independence as set out in APES 110 Code of Ethics 

for Professional Accountants.

Note 1 Significant changes in the current accounting period

On 31 January 2021, closing of the Agreement between Silex, Cameco and GEH for the joint purchase of GEH’s 76% interest 
in GLE occurred. As a result, Silex acquired a 51% interest in GLE and Cameco increased its interest from 24% to 49%. 
Several other agreements and documents were executed and closed simultaneously, including a site lease to enable the 
continuation of GLE’s operations at its Test Loop facility in Wilmington, North Carolina. The Agreement provides for deferred 
annual purchase payments to GEH totalling US$20 million consisting of four annual payments of US$5 million (shared pro-rata 
by Silex and Cameco) triggered after the first year GLE generates US$50 million in revenues. Various contractual arrangements 
have also been made with GLE partner Cameco, including an option for Cameco to potentially acquire a further 26% equity in 
GLE from Silex at fair market value. Silex’s 51% interest in GLE is accounted for as a joint venture which is further outlined in 
note 6 to these financial statements.
