Suvo Strategic Minerals : Trial Produces Premium High Reactivity Metakaolin - Gabbin

ASX ANNOUNCEMENT

28 April 2022

SUVO TRIAL PRODUCES PREMIUM HIGH REACTIVITY METAKAOLIN FROM ITS GABBIN KAOLIN DEPOSIT

HIGHLIGHTS

•  Suvo achieves major milestone with production of High Reactivity Metakaolin from its Gabbin kaolin deposit in Western Australia

•  Bulk sample results show equivalent or better quality than other Metakaolin products currently sold

•  High Reactivity Metakaolin in high demand for use in fast emerging low-carbon, high performance cement and concrete

•  Samples being sent to offtake partners for verification

Suvo Strategic Minerals Limited (ASX: SUV) ("Suvo" or "the Company") is pleased to announce it has successfully produced a bulk sample of High Reactivity Metakaolin (HRM) from its 100 per cent owned Gabbin kaolin deposit, located 215km north-east of Perth, Western Australia.

High quality HRM is used in the cement industry as an additive, or pozzolan, for ultra-high performance, high-strength and lightweight applications.

As a partial replacement for the traditional "clinker" binding agent, HRM has the potential to drastically reduce carbon dioxide emissions in cement manufacturing.

The Gabbin sample was prepared by global cement technology specialist FLSmidth using its flash calciner, at its Bethlehem laboratory in the United States.

While the commonly defined indicator of acceptable performance for HRM is based on a 90 per cent total of silicon dioxide, aluminium oxide and iron oxide, the Gabbin HRM product was measured at 97.8 per cent, showing equivalent or better quality than other Metakaolin products currently sold. Additionally, the Gabbin product was found to contain low quantities of certain oxides responsible for discolouration, meaning it has the potential to be used for production of whiter concrete. This has potential applications for high-end architectural design.

FLSmidth also found the caustic reactivity of the Gabbin HRM to be significantly higher than the minimum required of a pozzolan to effectively react with free lime to produce additional cementitious material. While a measure of 25 is regarded as very good, the caustic reactivity measured by FLSmidth throughout the trial on Gabbin HRM averaged 37.6.

This reactivity leads to substantial benefits in strength improvement, resistance to chemical corrosion and prevention of alkali silica reaction and efflorescence.

Metakaolin has been used by the cement industry for over 50 years as a pozzolanic to drastically reduce porosity, increase compressive and flexural strength, and offer greater durability and control of concrete breakdown caused by alkali-silica and other aggressive substance reactions.

Studies such as Beyond Zero Emissions' Rethinking Cement (2017) have shown that increasing the percentage of metakaolin used in cement has the potential to reduce carbon intensity by up to 40 per cent.

Cement production is estimated to contribute 8 per cent of global CO2 emissions, about the same carbon footprint as the global car fleet.

Suvo recently signed an agreement with Curtin University to investigate the application of HRM as a sustainable solution in decarbonising cement.

Suvo Non-Executive Chairman Henk Ludik commented:

"The successful bulk sample production of High Reactivity Metakaolin from our Gabbin deposit is an excellent result, which allows us to commence meaningful discussions with potential partners aligned with greening the cement and concrete sectors.

"On the back of the Company's recent decision to calcine kaolin supplied from our Pittong operation in Victoria, we see this as a crucial step towards diversifying Suvo's product basket and meeting demand for commodities with application in industrial emission reduction initiatives."

The release of this announcement has been approved by the Board of Directors of Suvo Strategic Minerals Limited.

Company Profile

Suvo Strategic Minerals Limited is an Australian hydrous kaolin producer and exploration company listed on the Australian Securities Exchange (ASX:SUV). Suvo is focused on production at, and expansion of, their 100% owned Pittong hydrous kaolin operation located 40km west of Ballarat in Victoria. Suvo's exploration focus is on near-term kaolin and high purity silica assets with 100% owned Gabbin (kaolin), Eneabba and Muchea1 (silica sands) projects located in Western Australia.

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.

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 products for end users. These products 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. Around 20-25kt per annum is supplied to various end users.

3.74Mt Indicated and 1.97Mt Inferred Mineral Resource of kaolinized granite.

Gabbin Kaolin Project

The 100% owned Gabbin Kaolin Project (White Cloud) is located 215km northeast of Perth, Western Australia. The project area comprises four granted exploration licences (E70/5039, E70/5332, E70/5333, E70/5517) for 413km2, centred around the town and rail siding of Gabbin.

The generally flat area is primarily cleared farming land devoid of native bushland and is currently used for broad-acre cereal cropping. A mining access agreement is in place over the current resource area with the landowner and occupier.

The main rock types at Gabbin are primarily Archaean granite, gneiss, and migmatite. These rocks are overlain and obscured by Tertiary sand and Quaternary sheetwash. The weathering profile is very deep and contains thick kaolin horizons capped by mottled clays or laterite zones. The current JORC 2012 Mineral Resources are 72.5Mt of bright white kaolinised granite with an ISO Brightness of 80.5%.

Eneabba Silica Sands Project

The 100% owned Eneabba Silica Sands Project is located 300km north of Perth, Western Australia. The project comprises four granted exploration licences (E70/5001, E70/5322, E70/5323, E70/5324) for 169km2 . The project is located on the Eneabba Plain whose sandy cover is very flat to gently undulating. Outcrop is rare due to the accumulations of windblown and alluvial sand at surface. Below this is a thin hard silcrete or lateritic claypan which overlies deep white and yellow sands. Preliminary exploration has included 54 drillholes for 1,620 metres to depths of up to 30m. This program is anticipated to deliver an initial resource for the project and a process route.
