SUVO TURNS NICKEL SLAG INTO HIGH
STRENGTH, LOW CARBON CEMENT
HIGHLIGHTS
Laboratory trials conducted in collaboration with Makassar State University
(UNM), in Indonesia, have successfully produced a high strength, low carbon
cement using a zero-carbon nickel slag.
The three samples tested showed exceptional results, with the highest
strength reaching 37.5Megapascals (MPa) after only 7 days.
The worldwide production of cement, the single largest industrial polluter,
equates to ~4.0 billion tonnes and results in ~3.2 billion tonnes of CO 2 per
year, representing ~8% of global greenhouse gas emissions and a significant
market opportunity for Suvo.
Nickel slag is the by-product generated from nickel production and is
commonly stockpiled or otherwise committed to landfill. More importantly,
nickel slag comes with a zero-carbon footprint.
The nickel slag used in this test program was provided by PT Huadi NickelAlloy Indonesia (PT HNI), a nickel pig iron (NPI) operation located in South
Sulawesi, Indonesia. PT HNI produces and stockpiles significant quantities of
nickel slag as part of its operations.
Suvo recently entered into a Co-operation Agreement with PT HNI for the
purpose of the parties considering whether to enter into a potential
commercial arrangement, including with respect to a partnership and or the
ongoing offtake of the nickel slag from PT HNI (ASX Announcement 10
September 2024). These negotiations are on-going.
Using standard apparatus, the testing of slump, initial and final setting time
and dry shrinkage will be performed in the second laboratory trial by UNM.

Suvo Strategic Minerals Limited (ASX: SUV) (“Suvo” or “the Company”) is pleased to
provide results from its recently completed laboratory trials completed by Professor
Subaer at Makassar State University (UNM), in Indonesia, targeting a reduction in the
carbon footprint of cement production, the world’s single largest industrial emitter
of greenhouse gas emissions.
The trials, using nickel slag, comprised of three samples which returned an average
strength test of 29.9Megapascals (MPa) after only 7 days, with the highest strength
reaching 37.5MPa.
Nickel slag, the by-product generated from nickel production, is commonly
stockpiled or otherwise committed to landfill. More importantly, nickel slag as a byproduct comes with a zero-carbon footprint as the carbon has been accounted for
and attributed to the nickel producer.
The nickel slag used by UNM was provided by PT Huadi Nickel-Alloy Indonesia (PT
HNI), a nickel pig iron (NPI) operation in Indonesia. PT HNI, being one of the
Country’s largest nickel producers, stockpiles significant quantities of nickel slag as
part of its operations.
In September 2024, Suvo entered into a Co-operation Agreement with PT HNI for
the purpose of the parties considering whether to enter into a potential commercial
arrangement, including with respect to a partnership and or the ongoing offtake of
the nickel slag from PT HNI (ASX Announcement 10 September 2024). These test
results are a positive step forward towards advancing negotiations with PT HNI and
the commercialisation of a low-carbon cement by the Company.
UNM will now commence a second laboratory trial using standard apparatus, testing
slump, initial and final setting time and dry shrinkage of the low carbon cement.
The results of both trials will be provided to PT HNI.
Executive Chairman Aaron Banks commented:
“We are excited to have commenced this workstream in Indonesia testing the by-
product of one of the Country’s largest miners, with our ultimate goal being to
manufacture an environmentally friendly and low carbon alternative to Portland
cement.
Achieving up to 37.5Mpa after only 7 days is an outstanding first round trial result
for the Company and could provide an entry into a large industry.
If the cement industry were a country, it would only be behind China and the United
States of America in CO2 emissions. The world use of cement is equivalent to
building New York City every 40 days.
The nickel slag used in this round of testing comes with a zero-carbon footprint
and the opportunity to play a part in reducing emissions in the cement industry is
analogous to the role of electric vehicles in replacing internal combustion engines
in the global passenger car fleet.
We will now commence the next round of testing with UNM and will provide the
results of both trials to PT Huadi which will allow us to advance negotiations with
respect to a potential partnership and or the ongoing offtake of the nickel slag and
commercialisation of a low carbon cement by the Company.”

Company Profile
Suvo Strategic Minerals Limited is an Australian hydrous kaolin producer listed on the Australian Securities Exchange
(ASX:SUV). Suvo is focused on expanding sales of hydrous kaolin produced at its 100% owned Pittong operation
located 40km west of Ballarat in Victoria. Suvo is also progressing commercialisation of the ‘Murdoch Technology’,
namely Intellectual Property for a geopolymer concrete batching plant a low carbon geopolymer concrete formulation
known as ‘Colliecrete’, which it licenses under a worldwide and exclusive Intellectual Property License Agreement.
Pittong Operations
The 100% owned Pittong Operations, located in Victoria 40km west of Ballarat, is the sole wet kaolin mine and
processing plant in Australia and has been in operation since 1972. Pittong comprises the Pittong, Trawalla and Lal
Lal deposits located on approved Mining Licences MIN5408, MIN5365 and MIN5409 respectively. The Pittong
processing plant has a name-plate capacity of 60,000 tonnes per annum.
At Pittong mining contractors deliver crude kaolin ore to stockpiles from the two currently operating mines, Pittong
and Lal Lal. The plant takes its feedstock from the ROM and it is processed into four separate product forms for end
users. These product forms are 10% moisture lump, high solids slurry, 1% moisture powder and 1% moisture
pulverised powder. The solids slurry is used in paper and board manufacturing. The other products are used in paper,
coatings, paint and specialist industries including rubber and pharmaceutical applications.
Geopolymer Concrete IP and Commercialisation
Suvo licenses the ‘Murdoch Technology’ from Murdoch University under a worldwide and exclusive Intellectual
Property License Agreement. The Murdoch Technology is namely Intellectual Property for a geopolymer concrete
batching plant a low carbon geopolymer concrete formulation known as ‘Colliecrete’.
Geopolymer concrete is a low carbon concrete that is made by reacting aluminate and silicate bearing materials with
a caustic activator, such as metakaolin, flyash, ground blast furnace slag and other waste derived materials.
Geopolymer concrete is a suitable replacement for concrete made using the traditional binder known as Ordinary
Portland Cement (OPC). The manufacture of OPC is a highly emitting process representing 8% of global CO 2 emissions
which is equivalent to the entire global car fleet.
Utilising the licensed IP, in a laboratory setting, Suvo has successfully produced three new geopolymer concrete
formulations using caustic activators, metakaolin and flyash. The laboratory trials ran tests comprising five samples
in each test returning an average compressive strength of 27 megapascal (MPa) up to 52MPa. The trials indicated the
geopolymer concrete formulations using metakaolin and flyash showed a potential greenhouse gas emission
reduction of up to ~70% compared to concrete made using OPC.
Suvo has entered into a binding Joint Development Agreement (JDA) with PERMAcast and is now in the process of
incorporating a joint venture entity (SPV Entity) to develop and commercialise low-carbon geopolymer concrete (GPC)
products. Under the binding JDA, Suvo and PERMAcast will prepare and test various formulations, assess their
suitability for different applications, and determine the best route for commercialisation through the jointly-owned
special purpose vehicle.
