ASX ANNOUNCEMENT

Australian kaolin producer and silica sand exploration company, Suvo Strategic Minerals Limited (‘Suvo or the Company’), is pleased to announce that refined clay samples from Trawalla contained up to 38.9% halloysite. Samples were submitted to James Hutton for bulk mineralogy by X-ray powder diffraction as part of the resource estimation at Trawalla. The samples analysed from Trawalla all contained halloysite with amounts ranging from 12.2% to 38.9%. Work is ongoing on other samples.

Commenting on the results, Suvo’s Executive Chairman, Robert Martin said “ The number of true halloysite-kaolin deposits are rare, those that are within granted mining tenure and close to a hydrous processing facility and yet to be developed, are at the moment non-existent, in this regard Trawalla stands alone. Trawalla offers Suvo the opportunity to be the first halloysite-kaolin producer in Australia utilising its currently operating production facility at Pittong. Suvo plans to use its current market position to not only complete test work with global leaders in the industry, but to also define additional market segments that can be addressed immediately with Trawalla clay.”

Technical Partnerships and Commercialisation Opportunities

On the 31 March 2021, Suvo announced an MOU and cooperation agreement with one of the world’s leading downstream kaolin and halloysite end-users, LIXIL, who is a Tier 1 multinational ceramic producer with annual turnover of A$ 20 billion to produce tailor-made premium quality refined kaolin products for the ceramic industry who will now also commence work on Trawalla’s halloysite-kaolin samples.

On August 5[th] , 2021, Suvo announced that it had signed an MOU and collaboration agreement with Rezel, the global catalysts and molecular sieve producer. Both parties agreed to develop further specialised, high-quality catalyst-grade premium kaolin products and technical solutions for the global catalysts industry. The Trawalla halloysite resource will help advance this technical partnership between Suvo and Rezel to develop a more functionalised halloysite-based catalysis product, molecular sieves and synthetic zeolites. Future research and development with Rezel will now also focus on halloysite nanotubes intercalated with catalytic metal nanoparticles and rare earth elements.

Together with Suvo’s technical and commercial partners, the company will now work to advance Suvo’s kaolin products based on its unique kaolin resources, and to help directly commercialise these products into global markets for their end user customers’ supply chains.

Trawalla halloysite-kaolin samples will also be sent to one of the world’s leading industrial mineral laboratories in the UK for further testing on its morphology, rheology, high-temperature firing properties for processing into “tailor-made” premium grade kaolin products based on the clay’s unique properties to identify its most suitable process and products.

Research and development work with BGRIMM, a leading mineral process technology and mineral product development research institute in China will continue to focus on batteries and super capacitors, developing Halloysite Nanotubes (HNTs) based modified and functionalised nanomaterials for carbon capture, hydrogen storage, water purification and coagulants.

ASX ANNOUNCEMENT

Simultaneously and together with Suvo’s existing customers, Suvo will carry out in-house research and development on medicine and cosmetic based applications as a special carrier and antiinflammatory agent based on the unique Trawalla halloysite-kaolin.

What is Halloysite

Halloysite is an aluminosilicate clay mineral in the kaolin group with the empirical formula Al2Si2O5(OH)4. Its main constituents are oxygen (55.78%), silicon (21.76%), aluminium (20.90%), and hydrogen (1.56%).

Halloysite naturally occurs as small cylinders known as Haylloysite Nanotubes (HNTs) and have a wall thickness of 10–15 atomic aluminosilicate sheets, an outer diameter of 50–60 nm, an inner diameter of 12–15 nm, and a length of 0.5–10 μm. Their outer surface is mostly composed of SiO2 and the inner surface of Al2O3, and hence those surfaces are oppositely charge.

Figure 1: HNT’s crystal morphology and atomic structure

==> picture [390 x 183] intentionally omitted <==

Suvo’s Trawalla kaolin is a naturally occuring hybrid blend clay of halloysite and kaolinite, containing halloysite with amounts from 12.2% to 38.9%. This unique blending offers Suvo the opportunity to produce premium quality kaolin products having both good plasticity, strength and casting properties, which is ideal material for ceramic manufacturing, a product that is not currently produced by the Pittong operations.

Unique naturally occurring nanotube structures leads halloysite into a wide range of nanotechnology applications, although the traditional use of halloysite-kaolin is in ceramic manufacturing, halloysite has also been used and has the potential for applications in nanocomposites with polymers, as vehicle for active agents, in medicine, agricultural applications, cosmetics, environmental remediation, as well as in nano templating, as supports for catalyst immobilisation and as a heterogeneous catalyst.

For medical applications, halloysite is not only used as a carrier for active agents and drug delivery, but is also used in wound-dressing, tissue engineering scaffolds as anti-inflammatory agents.

ASX ANNOUNCEMENT

Suvo, is currently one of the world’s leading producers of pharmaceutical-grade refined kaolin products from their Pittong operations. The halloysites from Suvo’s Trawalla kaolin resource will greatly assist the company’s in-house research and development on new pharmaceutical grade kaolin products and enlarge the company’s product portfolio for more medical applications.

Halloysite used in catalysis

Halloysite is an efficient adsorbent both for cations and anions. It has also been used as a petroleum cracking catalyst. Owing to its structure, halloysite can be used as filler in either natural or modified forms in nanocomposites. Halloysite nanotubes can be intercalated with catalytic metal nanoparticles made of silver, ruthenium, rhodium, platinum or cobalt, thereby serving as a catalyst support.

Research and development using halloysite with rare earth elements is also being actively carried out by the world’s leading fluid cracking catalyst producers, including Suvo’s customer and technical partner, Rezel Catalyst, who is co-owned by the second largest rare earth producer globally Shenghe Resources, who have in-depth knowledge on rare earth elements and experience in the supply of REE’s worldwide.

Carbon Capture

Physical adsorption of carbon dioxide on various mineral adsorbents is attracting attention in the field of energy and environment where Carbon Capture and Storage technology (CCS) is an option for CO2 emission reduction.

Halloysite has been assessed in terms of its potential use as a CO2 adsorbent as a natural occurring mineral with unique nanotube structure, large specific surface area, and special absorption and capture properties.

Owing to the layered structure of the halloysite, it has a large specific surface area, which can reach 117 m [2] /g giving halloysite the advantages of good absorbability. Both CH4 and CO2 sorption

suvo.com.au

9 September 2021 ASX ANNOUNCEMENT

properties of the measured halloysites were tested and were reported with good results which is very important for carbon capture technologies that require the use of significant amounts of sorbent.

Compared to synthetic nanomaterials such as activated carbon, zeolites, modified graphene or artificial nanotubes, the cost of mining halloysite-kaolin is much lower compared to the synthesis of nanomaterials.

The partnership between Suvo and BGRIMM, a leading mineral process technology and product development research institute in China will now also focus on development of HNT based nanomaterials for carbon capture and HNT CO2 and CH4 adsorbent to reduce carbon emission and for environment protection.

The two parties will also study HNT used in hydrogen storage , water purification and coagulants for municipal and industrial wastewater treatment, as well as developing a clay-based geosynthetic product to be used as a component in the rehabilitation of industrial or mining degraded areas.

Next steps

Further test work is underway to determine the Trawalla halloysite kaolin’s geological and mineralogical aspects. Morphology, rheology, calcination properties of the Trawalla halloysite kaolin mineral are planned to be tested and studied by one of the world’s leading industrial mineral laboratories in the UK. The aim of the research is not only to examine traditional ceramic manufacturing aspects of halloysite-kaolin but also develop a broad range of applications of HNT nanomaterials based on the unique properties of Trawalla halloysite kaolin.

Meanwhile, the research work with Suvo’s technical partner, BGRIMM, one of China’s leading mineral processing, technology and mineral product development research institutes will now be focusing on battery and super capacitors applications, developing HNT based modified and functionalised nanomaterials for carbon capture, hydrogen storage, water purification and coagulants.

Trawalla halloysite kaolin samples will undergo further testing and processing to be prepared into “tailor-made” premium grade kaolin products based on the clay’s properties, identify the most suitable process, and products together with end-users input and technical support.

Suvo plans to use its current market position as the only hydrous kaolin producer in Australia to not only complete test work with global leaders in the industry, but to also define and commercialise additional market segments that can be addressed from Trawalla.

9 September 2021 ASX ANNOUNCEMENT

The samples of refined clay were taken from drill samples as part of a resource estimation program being conducted at both Pittong and Trawalla. A total of 14 air core holes were drilled at Trawalla. Several of these holes have been processed at the Pittong laboratory in Victoria, which was initially established by ECC and Imerys, and the Nagrom Laboratory in Perth. Only T21005 has been processed by XRD to date but further work is ongoing to determine the full extent of the halloysite occurrence. Holes surrounding the discovery hole will be processed and sent for analysis.

The clay was refined by the Pittong method with the sample made down with water to 50% solids and blunged for 30 minutes. This allows the clay to be separated from the other constituents such as quartz.

The Pittong method uses 3kg samples to which 10% NaOH and 80% dispersant are added and the blunged sample is sieved at 0.25mm. The refined clay that settles after passing the sieve has the water poured off and the pH adjusted to 3.8-4.2 by adding acid. The clay is filter pressed, dried at low temperature, then analysed by XRF, sized by Micromeritics Sedigraph and a sample is sent for brightness analysis.

The refined clay samples all have halloysite with between 12.2% and 38.9%, the natural brightness of all of the samples ranged from 59.8 to 86.7, bleached brightness ranged from 64.3 to 91.3. These results highlight the potential of Trawalla refined clay to address high end ceramic markets. In addition, the impurities, Fe2O3 and TiO2, of the clay are low adding to its desirability.

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 redevelopment of, their 100% owned Pittong hydrous kaolin operation located 40km west of Ballarat in Victoria. Suvo’s exploration focus is on their 100% owned White Cloud Kaolin Project located adjacent to Gabbin in the Central Wheat Belt, and the 100% owned Nova Silica Sands Project located in the Gin Gin Scarp near Eneabba, both situated 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.

Current Reserves and Resources at Pittong are reported to PERC code and are in the process of being upgraded to JORC 2012 compliance.

The White Cloud Kaolin Project

The 100% owned White Cloud Project 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 413km[2] , 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 White Cloud 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%, <45m yield of 41.2% results in 29.9Mt of contained kaolin.

Nova Silica Sands Project

The 100% owned Nova 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 169km[2] .

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.

Scoping Study

The White Cloud Kaolin Project Scoping Study (the “Study” or the “Project”) referred to in this ASX announcement was first announced on 27 May 2021, is conceptual in nature and has been undertaken to assess the potential for the development of the Project. The Study is based on the Mineral Resources set out below. The Study is preliminary in nature and, although based entirely on Indicated Mineral Resources, the overall deposit includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied that would enable them to be categorised as Ore Reserves. Mineral Resources are not Ore Reserves and do not have demonstrated economic viability. The Study includes a preliminary economic analysis based on a number of possible production targets (“Production Target”) and assumptions on Modifying Factors and evaluation of other relevant factors estimated by a Competent Person to be at the level of a Scoping Study. The Study outcomes, Production Target and forecast financial information are based on information that is considered to be at a Scoping Study level. The information applied in the Study is insufficient to support the estimation of Ore Reserves. While each of the Modifying Factors was considered and applied to a level that is considered to be appropriate for a Scoping Study, there is no certainty of eventual conversion to Ore Reserves or that the Production Target will be realised. Further exploration and evaluation studies are required before the Company will be in a position to estimate any Ore Reserves or provide any assurance of an economic development case.

Some bulk samples of Trawalla material have been processed through the Pittong Process plant.
Geology		Deposit type, geological setting and style of mineralisation.	  	The Trawalla deposit was formed from the meteoric weathering of coarse-grained granite mainly composed of quartz and feldspar with minor amounts of other constituents. Trawalla is considered to be a weathering deposit. The intense weathering of this rock has dissolved and leached selected constituents in the rock and formed an in-situ deposit of white kaolin, halloysite and quartz. Kaolinite and halloysite are silicate clay minerals of interest. The feldspar in the granite has been altered to kaolinite and halloysite. Kaolinite and halloysite have the same formula - Al2Si2O5(OH)4, kaolinite is a platy silicate clay mineral, halloysite has a tubular crystal structure.
