- Best undiscovered project: Carlow Castle an unconventional Gold-Cobalt-Copper mineral Project
To me, Carlow Castle is a strange project that has been around for a long time. It even had a small resource but the general public would never have heard of it. It was as if it was unloved and was one of the projects that would be stranded. It was all about lithium for a while and then suddenly cobalt reared its head up. I came across the project only when I became a shareholder of the company many moons ago. The company started pumping out announcements and I thought hey, I am a shareholder of a cobalt company. After doing some research on the project, I came to feel that this Carlow Castle project was the thing, it had real potential to be something great. Then the conglomerate gold rush came and it was all on for the punters… 🙂 I still felt that Carlow was the prize. At that time, I was a firm believer in the resurgence of base-metals and Ni especially. I also became a copper fan for some reason. Anyway, Carlow to me was all about this part of the equation and I was happy that I was in on the action. Like my normal thing, I just let the market do its thing and I was very comfortable with the team at Artemis, after all, they have vested interest to make the share price go up too. That part happened and then everyone was happy… however, I have yet to see Carlow become the mainstay of the company till now… well, I hope that’s what it will mean. On the 31st January 2018, Artemis Resources Limited (ASX: ARV) announced the following, 4.5 Mt of Cobalt/Copper/Gold JORC Resources at Carlow Castle – Karratha, Western Australia Highlights: Significant increases in Carlow Castle JORC 2012 Resources. JORC 2012 compliant Indicated and Inferred resources at 0.05Co cut – off grade, have increased to 2.3 Mt @ 1.3 g/t Au, 0.11 Co, 0.5 Cu & 1.6 g/t Ag within a global resource of 4.5 Mt @ 0.9g/t Au, 0.07 Co, 0.4 Cu & 1.3 g/t Ag. Deposits remain open and further drilling is planned in Q1 to expand resources. Open Pit optimisation studies and scheduling have commenced. Carlow Castle is only 30km north – east of Artemis’s Radio Hill treatment plant. On the 29th August 2018, ARV announced what I think is a significant addition to the deposit. The interception length and the grades observed in my opinion shows that the company may be showing signs that they have a better handle on the mineralisation. The image below is a part of the announcement. It is on the Artemis website. I am not saying that this is going to be a world class mine. However, I am now happy that more work is being done and have become more than intrigued by the potential of this project. The length of interception announced has got to get people excited, if not, they need to get their heads examined. It is nice to see that amount of drilling and the results are looking to be building a nice picture. I hope that the management will continue to take the punt and drill this bugger out. I can see that there appear to be zones happening. A more gold-rich zone and a more cobalt-rich zone ( or a less gold-rich zone). This announcement follows another on the 6th August which also shared some great intercepts which I believe shows the consistency that is needed to make this project viable from a technical point of view. The commercial viability part will need more work. The crew in Artemis have done an excellent job in doing the drilling the correct but painful manner. There have been many projects that have been drilled out in a hurry to please the equity markets. I guess it is a easy thing to do when you have loads of cash to drill holes. It is easy to be good when you have the money to test ideas and concepts :-). One of the things I would have a concern would be it’s the mineral assemblages… Too much copper/cobalt and you have a headache… The amount of this and that is not always a good thing in mining 🙂 However, I guess having a good problem to wonder about is better than not having to wonder about a bad problem. According to a release on the 19th June 2018, Artemis mentioned the following, 67.30 Gold Recovery (calculated head grade 13.8 g/t Au) 55.50 Cobalt Recovery (calculated head grade 0.84) 87.40 Copper recovery (calculated head grade 2.16 Cu) Those numbers are not the best, but it will do for now. As I mentioned the downside of this project, in my humble opinion is the metallurgical factors. The recovery rate of 67.30 is not fantastic, but I think with the time that they have, I would hope that they will try and work that out. The good thing about the team at Artemis is that I can see grey hairs mixed amount no hairs… Means that they have been around and have done much thinking… 🙂 One of the things I like about Carlow Castle is that it has an excellent chance to be an open pitable mine, and the future resource upgrade should make it very viable. There are probably many technical people out there that will argue, but I will preferably be on the side of most likely than most unlikely at this stage. If they can make the resource bigger and get a really good handle on the structure and metallurgy, this will be a great little project. I agree that there is still a long way to go. There may still be many issues that may be counter-intuitive to making Carlow attractive, so time and spending those millions in the company’s bank account will be important. Logistically, this is a great place. Carlow is a stone’s throw from Karratha and the infrastructure will a non-issue. As mentioned, the geology is complicated, and this is good because this could mean that there will be more goodies hidden (the ever optimist in me is always looking at the bright side 🙂 ). As I mentioned earlier, traditional EM (Electro-Magnetic) , IP (Induced Polarisation) nor magnetic geophysical surveys have not picked up Carlow. It appears that only SAM (Sub Audio Magnetic) was effective. For those interested in understanding more, please feel free to contact the buys at Artemis. I am sure they will give a better explanation than me. Structurally, the last announcement made mention that the mineralised body seem to be turning south. This is another encouraging new information and could lead to more upgrades. The next phase of drilling will be very interesting. However, I would say that we all need to be patient as it will take more than a couple of drill holes to define where the mineralised body is heading. As easy as it turning south it could also face more change in direction. As I keep mentioning, the complexity of the deposit is a good thing as long as the drilling keeps following any new ideas. You probably will never see it in the same category as Bou Azzer , but it will likely find its level of significance. Like many of these cobalt hopefuls out there, there is a big difference in a project that can work or a project that cannot work. Blackstone Resources (ASX: BSX) went to Canada to drill a high-grade Cobalt project and was riding high with its share price reaching a high of AUD$0.66. Another drilling program later and they are now at AUD$0.11. Logistically, they were also in a challenging area. If they had a positive result from their drilling, they would have had to figure out how to manage the processing part. Most investors out there would not think about this. I must admit that I sometimes feel like that as well. Why bother about those silly things like whether a mine is ever going to be built in that place, even though it could be in that godforsaken place… 🙂 In the heat of buying shares, one can easily overlook some silly but essential factors :-). Carlow on the other case is flat, and the only hill is that from an ant. I visited the place in October 2017 with great thanks to Artemis Resources. A smooth drive on bitumen road north and then a turn south on a dirt road and you are on site. Not precisely remote by anyone’s definition. As you can see in the photos above, the area is a fantastic place to work. All you have to worry about is the extreme heat in summer and the flies between the seasonal change between the cold and hot seasons. With all the right points that we have mentioned, there is one issue that is worth mentioning. There is an increasing amount of regulatory obligations that a company has to go through these days. I understand the head banging issues and the whole waiting for approvals…etc. However, I see that as just part of the cost of business. As a sagacious man once told me (he has little hair left, whats left is white and is of an age that is north of 50) a convenient thought. In Africa, you deal with the ownership and corruption and guns, in Asia, you deal with the ownership and the corruption, in PNG, you deal with land ownership and corruption (personal experience), in Australia, you deal with the Mines Department and the Environmental madness… So I think it is an even distribution of issues. I remember a very prominent person in West Perth saying that he spent continuous days in a North African (could have been Eritrea) minister office waiting for a signature….. But I believe they sold that project after doing work for many millions and they did well. From a former company director and exploration student, Carlow is an excellent project to grow. I do feel that there is a great chance of Carlow making the grades. Looking at the projects in the small company space (although the market cap of ARV is not tiny), there are very few “base-metal” projects (I don’t like the Battery mineral terminology) out there that gives me the feeling of growth and blue sky. Most would look at the resource number and say its small. The more detailed investigation will most likely make it even smaller with many questions, but I think there is still a lot of meat that will make Carlow Castle the dark horse in the Cobalt scene. Remember that as much as the associated minerals can become an issue, if resolved, this can be a massive positive. If all the credits make a play, this deposit, whether it is a Cobalt, Gold or Copper project, will become very cost effective and make a lot of money for ARV. I have purposely made little reference to Carlow Castle as a cobalt project because I think this jury is still out having lunch. When I was last having conversations with associates, who have many opinions, we all agreed that this could have as much chance of being a gold deposit as it is to be a cobalt project and a minor extent a Copper deposit. In conclusion, I do feel that this is one of the better projects to watch. Very complicated but there is enough smoke already to show that this is a project worthy of keeping and nurturing. In my opinion, this will add value to the company and will have more chance of making a mine than not. Just in case people are wondering, I am not a shareholder of this company at the time of writing…….

- Cellulose Fibres from Organic Waste - Nanollose (ASX: NC6)
Nanollose (ASX: NC6) is an ASX listed company that is trying to make Cellulose fibres from organic waste. Like me, you ask, what is cellulose fibres? In a simple chinaman explanation, cellulose fibres are fibres made of esters of cellulose which can be obtained from the bark, wood or leaves of plants, or plant-based material. These fibres are compound of hemicellulose and lignin, and different percentages of these components are responsible for different mechanical properties observed (source: Wikipedia). The main applications of cellulose fibres are in the textile industry, a chemical filter, and fibre-reinforcement composite, due to their similar properties to engineered fibres, being another option for biocomposites and polymer composites (source: Wikipedia). Manufactured cellulose fibres come from plants that are processed into a pulp and then extruded in the same ways that synthetic fibres like polyester or nylon are made. Rayon or viscose is one of the most common “manufactured” cellulose fibres, and it can be made from wood pulp (source: Wikipedia). A couple of weeks ago, I heard about Nanollose from a passing conversation. It intrigued me for a few days as this is something very different from my comfort zone so I started to look into the company. I have had a lot of interest in Hemp in the past and have done a couple of Insights on that topic so as I researched, the similarities started to appear. Hemp – A very Green Construction Product. Cannabinoids: Now I know what the fuss is all about…… The creation of natural fibre from the use of organic waste will fit into one of the “clean products” that the world is seeking. It is probably got a few hurdles to get over before full commercialisation, but it will be a good conversation with management for those people that are keen to find out more. I am sure you will be able to get all the contact details from www.nanollose.com . I spoke to Alfie Germano, the managing director, and he gave me a quick introduction to the industry. For me, it is a unique concept and one that I think could prove to be very lucrative. In December 2018, the company announced that they had created their first garment from their Rayon. The first garment was created from the conversion of organic waste. You can see the process in Figure 2. Simple in nature, but I am sure that is not entirely the case. However, this process would help with the environment. I know how bad the cotton industry is for the environment, so I welcome anything that can reduce that industry. I am already all for Hemp as an alternative to cotton. While researching this company, I also learnt about Rayon and the market. It is something that I would not have thought about even though I am wearing clothing all day. According to Wikipedia, Rayon is a manufactured fibre made from regenerated cellulose fibre . The many types and grades of rayon can imitate the feel and texture of natural fibres such as silk , wool , cotton , and linen . The types that resemble silk are often called artificial silk . Since rayon is manufactured from naturally occurring polymers , it is not considered to be synthetic [1] . Technically, the term synthetic fibre is reserved for fully synthetic fibres. In manufacturing terms, rayon is classified as “a fibre formed by regenerating natural materials into a usable form”. [2] Specific types of rayon include viscose , modal and lyocell , each of which differs in the manufacturing process and properties of the finished product. Rayon is made from purified cellulose , harvested primarily from wood pulp , which is chemically converted into a soluble compound. It is then dissolved and forced through a spinneret to produce filaments which are chemically solidified, resulting in fibres of nearly pure cellulose. Unless the chemicals are handled carefully, workers can be seriously harmed by the carbon disulfide used to manufacture most rayon. I find this topic very fascinating, and I guess Nanollose allows me to get involved in what is considered clean for our environment and has a large market. Rayon is a high growth market valued at US$16.3B in 2019 and growing at over 10%, according to Nanollose. Figure 3 below gives a summary of the composition fo the market. Nanollose has a facility in Indonesia where they are looking to source the waste of a coconut food product manufacturer. So systems are in place to move their plans forward in 2019. Corporately the share price for Nanollose has not been performing well but I think there is room for improvement. The investing market is always looking for something different I think with time and the right marketing, this could be a worthy product. I could go on for a while on this, but I think it is best to have a look for yourself and check it out. I can see several barriers for the company to reach its target. Acceptance, by the market, the endurance of the fibres for the garment industry, proving that the material has no adverse health considerations and the ability to sustain the competitive barrage from traditional fibres. All these thoughts may be overcome with time and endurance to stay in the game. I am thrilled to have found this topic, and it is worthwhile to do more research.

- Aurumin Limited (ASX:AUN) - The Beginnings of a Gold Producer.
Rooster Talk Episode 54 is with Brad Valiukas, Managing Director of Aurumin Limited (ASX: AUN) The time has come for Aurumin Limited (ASX:AUN) to step up and deliver on its aspiration to become a mid-tier gold miner. We know where the ounces are, we are going to try and deliver a result. - Brad Valiukas. In this episode, we get an update from Brad on the path forward for Aurumin after completing the acquisition. We spoke about how management was going to plan the work that will be happening over the next 12 to 18 months. Mt Dimer, Mt Palmer and Johnson Range are still core projects for the company. However, with this acquisition, the Sandstone project is a step up. In saying that, Brad assures us that there is a lot of work still to be done with the existing projects. There is no question that the acquisition is a big value add to the company. However, markets do have a mind of their own when it comes to valuation. Personally, if you look at what is in the project with the Two Mile Tonalite, if management can make this work, it will be a game changer. This is a good groundwork for investors and I strongly encourage those investors who have done their own research to seek out Brad. Talk to him and ask him what his thoughts are and his reasons for acquiring Sandstone. Chapters: 00:00 Start 00:25 Introduction 00:53 Brad discusses Sandstone acquisition. 01:08 How will the new Sandstone project fit into Aurumin. 02:12 How is the Mt Dimer project going? 04:49 How does Aurumin plan the exploration? 07:40 Does exploration change depending on results? 09:35 The Two Mile Tonalite - The Prize. 11:16 The Pegasus Story - The Hidden Jewel of Sandstone. 12:24 The news ahead for Aurumin. 15:04 The Ultrafine Sampling Success. 16:17 Reasons to look at Aurumin. 17:23 Conclusion PODCAST This is a good time to download the first Ebook (FREE) from Samso as it is all about VMS (Volcanogenic Massive Sulfides).

- Revolver Resources Limited - An Elephant Copper Deposit Discovered in Queensland, Australia
Coffee with Samso Episode 142 is all about Revolver Resources Limited (ASX: RRR) discovering what is looking like a giant Copper Deposit in Queensland. In this episode of Coffee with Samso, we explore a company that is developing a great copper deposit. Revolver has two assets in north western Queensland, Australia. Little is known about these assets. The company had worked on these projects for 7 years in a private capacity and were listed in 2021. The company is well funded, cashed up and is in the process of unlocking the value of Dianne and Osprey. These two projects headline the company with both showing enormous potential. Pat Williams, Managing Director of the company speaks to us about the dedication of the company to produce value for shareholders by systematically going through the process of exploration while keeping a tight reign on costs. The recent discovery of the Green Hill corridor speaks volumes of the potential of Dianne. Green Hill prospect is not looking to emulate a size of three football fields, and the results are indicating that the size could grow further. Operation on site commenced in the first half of Oct 2021-2022 and continues in the wet tropics. The work completed includes surface mapping, regional surface sampling, an extensive IP program and a 17 hole DD program. Diane is open in 3 remaining directions. Osprey is poised to be a Tier 1 project. The company has conducted 3 IP programs and continues building the geophysical signatures. The project is already showing indicators of a halo typical of an IOCG (Iron Oxide Copper Gold) system. The talented and experienced Board of Management are hands on actively exploring its tenements and pursuing further acquisitions as well as creating additional Shareholder value. Let's listen to these chapters: 00:00 Start 00:20 Introduction 01:10 The Dog with two Tales. 01:30 Pat Williams Introduction. 04:50 Transition from private company to public listed. 07:03 The Dianne Copper Project. 14:56 The prospectivity of projects like Diane. 16:50 Is the Dianne project an underexplored system? 24:11 The Green Hill prospect. 26:43 The other project - Osprey. 34:12 The value of WMC projects. 36:17 The pedigree of Osprey. 40:48 What could hamper your project and how are you countering these issues? 45:21 What are the news flow that investors can expect? 49:14 Why RRR? 50:21 Conclusion PODCAST About Patrick Williams Qualifications: BAppSc (Mining Geology), MSc (Mineral Economics), MAus/MM Pat Williams has worked in the global resources business for more than 30 years where he has held senior roles with several international mining operations from the front line through to the boardroom.

- Good Geology Never Disappoints - Los Cerros Limited (ASX: LCL) Colombian Style
With every company and thought leader I listen to, I am learning more and more about what makes a good mineral province. It is amazing what you learn when you start listening to the stories of people in different industries sharing their knowledge and experiences. Definitely one of the big perks of growing older - we gain experience and insights. We are like wine, the older it is, the more interesting the depth of flavours. In geology, especially mineral geology, I have learned that finding great deposits is all about understanding the regional geology. Once you have understood the provincial aspects, the local geology specifications become clearer. What this means is, investors who want to know the likelihood of discovery, the likelihood of mineral exploration success and hence the probability of investment success should just stop and look at the bigger picture first. I know there are other non-geological aspects that are equally or more important, but one has to recognise that science and facts do not allow the truth to be stretched. The Colombian Story I first came across the Colombian story almost 5 years ago when I came to know about Andes Resources Limited. Andes was unlisted at that time and has now resurfaced with a new name as Los Cerros Limited (ASX: LCL). Prior to this, I have never looked at Colombia as a resource jurisdiction. I suspect this is due mainly to the lack of visibility in the ASX. I was privileged enough to have Jason Stirbinskis on Coffee with Samso - Los Cerros Limited (ASX: LCL) - A High-Grade Gold Porphyry Story in Colombia to talk about the project. While researching for our conversation on Coffee with Samso, I learnt about the prospectivity of this little part of the South American continent. I dare say that I am not the only one who does not know much about the prospectivity of Colombia. What is so Interesting about Colombian Geology ? As we have discussed in a previous Samso Insight - New England Fold Belt - Critical Resources Limited (ASX: CRR) - the importance of understanding the potential of a project/deposit is underlined by the understanding of the tectonic history/controls. What I mean is, do the potential geological controls allow the story to be achievable? Does the stated resource potential have any chance of being attained? The Andes can be divided into the Northern Central and Southern. The Colombian story is in the Northern Andes and it consists of three cordilleras ( Western, Central and Eastern), which are themselves internally complex as well (Figure 1A and 1 B). Figure 1: A: Tectonic scheme of northern South America and the Caribbean (Gómez et al., 2015a, 2015b). [1]. B: Lithotectonic map of the Northern Andes showing the location of the Miocene Buriticá, Quinchía, Marmato, and La Colosa gold deposits (modified from Cediel et al., 2003). [5] This region is complicated in the sense that there are subducting plates and then there is lateral movement of plates as well. As you read, I will try and explain in layman´s terms what it means when I say that the mineralisation can be directly related to the level of magmatism. To put it simply, it appears that certain types of subduction activities do not create volcanic activities and hence, a lack of mineralisation (Figure 1B). Tectonic Activity According to [1], the tectonic framework of Colombia (Figure 1A) is influenced by the interaction between the Caribbean and Nazca oceanic plates, and the South American continental plate, with ocean ridges, oceanic trenches, subduction zones, accretionary prisms,formation belts, transform faults, and several other structural elements, as defined by [2] and [3] based on the findings of numerous researchers (Figure 1A, 3A and 3B). To say this is an oyster of structural complexity would be an understatement. The more I read about the geology, the more it starts to make sense to me. What is obvious is that we are looking at a serious subduction zone - the Northern Andes is a series of plate consumption and plate creation. What this means for the average investor is that the structural component of the cooking mechanism means the mineralisation process is in place. Like all scientific explanations, there are a lot of variables that create outliers, so I will try to stay as basic as I can. Geology and Magmatism It is obvious then, that the rocks (Figure 2) in this area is the product of the subduction zones and the collision of the three plates and the segmentation of plates. Looking at the geological map, you can make a safe assumption that the majority of magmatism is concentrated with the three structural corridors of Western, Central and Eastern Cordillera. Figure 2: Geological map of Colombia. After Gómez et al. (2019).[1] What is interesting is that [4] talked about how the level of volcanism is restricted to the central region, between the eastern portion of the Western Cordillera and the Central Cordillerra. You can see the the results of that paper in Figure 3B below. Figure 3: A: Main geological structures of Colombia. After Gómez et al. (2019). [1] B Seismicity and volcanism of NW South America. Black arrows indicate plate velocity relative to stable South America [Trenkampet al., 2002], red triangles indicate volcanoes. Coloured circles indicate earthquakes recorded during 1993–2009. Earthquake data are downloaded from National Earthquake Information Center website (NEIC, ttp://earthquake.usgs.gov/regional/neic/). [4] It is not surprising then that Epithermal and Porphyry style deposits dominate this province. Tectonic settings like this discussion is the prime candidate for creating a recipe for large high grade deposits that are being discovered in the last decades. That line of red triangles in Figure 3A is also consistent with the known giant deposits that are in Colombia. There is a glimpse of that in Figure 1B where the massive Buritica Gold Deposit headlines that northern trend and the recent discovery of the Alpala (Cascabel) discovery by SolGold sits at the bottom end of that trend in Ecuador (See Figure 4A and 4B). Figure 4: A The summary of the Buritica Gold Mine [6]. B The overview of the Alpala deposit by SolGold. [7] Magmatic Belts and Ore Deposits [5] talks about six magmatic belts with ages from Triassic to Neogene. I won´t bore you with what they mean but it is sufficient to say that they are very young and are forming geologically even as you read these words. In fact, this is not far from the truth as magmatic activities are brewing literally today. As I mentioned earlier, the main type deposits are Porphyry Cu- (Au-Mo) and Epithermal Au-Ag deposits. In the above section, I have listed two known giant deposits. There are still relatively few discoveries and that may be solely due to the geopolitical issues in the past. Figure 5 below is a good depiction of the type of ore deposits in Colombia based on the ages and the structural constraints and the volcanic activity shown in Figure 3B. Figure 5: Gold metallogenic belts and major Mesozoic and Cenozoic intrusive rocks of Colombia (modified from [8], and [9]) [5] There is this consistent reference to that region where we see the most volcanic activity. Conclusion Whenever I do my research when preparing for a Samso Insights, there are always lots to learn. In January 2020, I published Copper Porphyry Districts - Chile & Associates which was a pretty long blog. It was a 12 minute read, and in terms of attention span, it really tested readers. But that Insight was a real eye opener for me. As I mentioned, the Colombian mineralisation story was only something on my radar screen after I did the Coffee with Samso with Los Cerros Limited. I must say that I did not know that there was such a a thing as a high grade porphyry gold deposit. What is interesting is that even today, investors in the Australian Stock Exchange (ASX) are not fully well-versed in the potential of Porphyries and Epithermal deposits as being a giant target. There aren´t too many stories in the market place now that are in the same league as the Los Cerros of the market. Just look at Cadia-Ridgeway (NSW, Australia), Ok Tedi (Papua New Guinea), Bougainville Copper (Bougainville), Batu Hijau (Indonesia), Grasberg (West Papua, Indonesia), Tujuh Bukit (Indonesia), Bingham Canyon Mine (USA), Escondida (Chile)...etc these are mines that go for generations. When I look at what Los Cerros have and the results they are releasing lately, I can´t help but think that the limiting factor for the company is funding. The Quinchia deposit is a well-known Colombian deposit and when you look closer, there are satellite deposits as well. I came across [10] and wanted to share this (Figure 6) as it shows that the Los Cerros project is not some unknown topic. The whole Colombian story is a revelation for me. At this time with the geopolitical situation and the onset of rising interest rates, having a large high-grade gold deposit will be a good story. Figure 6: Location maps of the study areas.

- Drilling for Success - Lake Austin Gold Project
Standing looking at the drilling and mineralisation trends of the Lake Austin Gold Project, I was trying to remember what is so familiar about this place. I kept looking for something familiar, and I can see the words, Lena Shear, but I kept thinking I know this place. I was intrigued by this Lake Austin Gold Project. The fundamentals have indeed perked my curiosity. I started talking to management to learn the story. I told them that I know the Tuckabianna project and I had walked all around the project in another career path. This Lake Austin Gold Project seems to remind me of something south-east of Cue or south-east of Mount Magnet. The Lake Austin Gold Project are all within a 30km radius from the township of Cue. The mining town of Cue is about 650km north-northeast from Perth, Western Australia (Figure 2). As many would know, Cue is no stranger to mining. This Murchison region is one of the most endowed goldfields in Western Australia with gold mines producing in multiple of millions of ounces. The mining centre of Mount Magnet, Cue and Meekatharra has been active for decades, especially in the 1990s. I was informed by “experts” that the gold nuggets you find in the Murchison are cleaner and purer, but I don’t know how much is myth or truth. In 2008, when I was making my first trip as Exploration Manager for Silverlake Resources Limited (ASX: SLR), I met a prospector who had these nuggets shown in Figure1. He told me the story about how Murchison gold is the best, and I guess it must be true. Don’t all prospectors know everything……… Musgrave Minerals Limited (ASX: MGV) I came to know about Musgrave Minerals when I attended a presentation in Perth organised by Cannings Purple several weeks ago. Hence when I participated at the RIU Conference in Sydney in May 2019, I was keen to catch up and get an update on the projects. After the initial presentation in Perth, I felt that this Lake Austin Gold Project had a lot of promise. These big intercepts were worthy of being a discovery. I don’t doubt that there is a big story here, but I was just conscious of the grades. They were not too shallow, also, which was my main concern. When I talked to Musgrave in more detail, I realised that although my initial concerns were valid, what I was learning is that we could be dealing with a much bigger system. The real light bulb moment for me is just a few days ago. I realised why this place was so familiar. This Break of Day project was the old Moyagee project from my days at Silverlake Resources. When I realised this and knowing the discovery to date, I was suddenly very optimistic about the project. So much so that I started doing some Samso style research. This also explained how Silverlake Resources became a significant shareholder. Close to Infrastructure In terms of logistics, the project is well within many operating mills (Figure 3). Hence, one can pretty much say that they would look at toll treatment when they get to a mining scenario. There are a lot of choices, and if they find more ore, I am sure the other mills will all be chasing them for business. However, drilling may later show the economics to build their mill closer to the action. According to the presentation given at the RIU conference in Sydney, the district has over 20M ounces of historical gold production. The primary gold system at Cue is over 28km in length/strike. The upsell of the Lake Austin Gold Project is the possibility that it could be a Great Fingall look-alike (Figure 4). I think they are probably not too far from that theory and creating a legacy of their own. One cannot have this amount of good results and not go down the road of production or at least produce an excellent resource scenario. Break of Day and Lena Gold Projects These are the Moyagee projects from Silverlake Resources, and it is good to see that the thinking from back then has been followed up. In my time there, we were going to drill that area, but circumstances prevented that from happening. The resource was already there, and I guess the drilling that Musgrave completed proved that the system was in place and there were more legs to the story. The new drilling proved that the mineralisation did indeed go more in-depth, but I don’t think this is going to make the custard. There is not enough width, and the grades are not spectacular (Figure 5). The numbers show some promise but I think there is just not enough work done and with the discovery of the Lake Austin Gold Project, I can’t see management diverting money to this project. As I mentioned, what this do show is that the system is mineralised and I think the potential of a separate “district” is very high. I do believe that the potential shown in Figure 4 is not a pipe dream. I remember when I was at Silverlake, I liked the Lena Shear system. I felt that it is consistent and the system had the potential to be part of a bigger, more endowed metallic system. I did think that the management at that time was more interested in Daisy Milano and rightly so as the mishap at the Lakewood mill nearly took them underwater six months form raising 30M from the IPO. I am glad that the recent drilling from Musgrave have shown that I was correct and the discovery of Lake Austin Gold Project in potentially the same system is even more exciting. This system may be sparked by the Break of Day/ Lena Shear System. Lake Austin Gold Project The Lake Austin Gold Project has all the hallmarks of a great future mining project. The recent drilling results have been pretty spectacular. The presentation slide (Figure 6) showing all the recent intercepts is fantastic and has some good length to the intercepts. They are very encouraging, and one would have good reasons to think that this could be early signs for duplicating the Great Fingall deposit. This potential that management is hoping for may not be all myth after all. Asking me would be biased as I am always an optimist and an exploration geologist. We still think there is a pot of gold at the end of every rainbow… eventually 🙂 Looking at the other announced results in Figure 7, it does give one a clearer understanding of the potential. The mineralisation of 242m @ 1g/t is fantastic, as there is a high grade of 45m @3.3g/t. As I have mentioned in previous articles, intercepts of 242m, 84m and 94m are lengths of drill intercepts that make mines. The grades may not be high enough to excite, but you have to understand the mix of high grade and lower grade components of the deposit. The challenge for the company will now be to drill this out and hope that they come up with a decent resource and reflecting a suitable grade. There does look like a consistent link to the trend heading in a northeastern orientation. I can’t help but think that the Lake Austin Gold Project is the confirmation from Break of Day and Lena. Subsequently, I feel that the Mainland project could be the confirmation from Lake Austin. All they need to do now is drill and drill and drill. When you look at the diagrams within Figure 6 and Figure 7, one can see the potential of a mineralised belt happening, This structural splay coming off that central north-south shear zone could be what the Musgrave needs to make their “Great Fingall” theory come alive. The Gravity data show observable targets and good correlation to the orientation of mineralisation and a structural corridor. Conclusion Musgrave Minerals has got themselves a project that continues to uncover more ounces. This project reminds me of the discovery that started from small intercept to one of the most well-known salt lakes. Lake Lefroy in the Kambalda area has one of the most metalliferous endowed salt lake systems. Figure 8 shows the discovery around Lake Lefroy over 40 years of activity. The development of Invincible was the latest, but that also took several years due mainly to not recognising the importance of early exploration results. The discovery of Invincible in 2012/2014 is active in my mind as that was a 1.3M ounce discovery in an area that you would have thought had been thoroughly drilled out. To me, Musgrave could be onto something that could make them a producer or a takeover target . Thick intercepts and decent grades are the right combinations of a good story that would attract corporate activities with the gold price continued rise up the charts. What could make this come a cropper would be running out of money. Musgrave has strong shareholders, Westgold is a major shareholder and they would be the first to benefit if Musgrave defines a workable resource as the nearest toll treating avenue is their Tuckabianna Mill. Apart from a lack of funding, I don’t think there is anything else that could make this a lemon. Even a chinaman geologist like me could make myself a hero from here…maybe… 🙂 Disclaimer The information or opinions provided herein do not constitute investment advice, an offer or solicitation to subscribe for, purchase or sell the investment product(s) mentioned herein.

- Indigenous Women In Mining - Challenges and The Future.
Coffee with Samso Episode 95 with Florence Drummond, CEO & Co-Founder of IWIMRA (Indigenous Women in Mining and Resources Australia). IWIMRA is an organisation that aims to create a stronger connection amongst Indigenous women in Australia’s Mining and Resource sector. With the whole ESG factor developing, I have been looking to seek the Social aspect of the ESG. My thoughts are that the key component of making ESG work is to create a greater awareness of First Nation requirements. I saw Florence Drummond on LinkedIn with her cause and I wanted to get her onto Coffee With Samso to share with us her work. The mineral resource sector is a high value component of Australia's GDP, so it would make perfect sense to encourage the First Nation population to participate in the continued growth of the industry. Mining projects are in remote areas, and as Florence shares, it makes sense to encourage the indigenous population to join and create wealth in the community by encouraging employment. Florence comes across as an energised ambassador of this cause and I was thankful for her to participate in the Samso ESG series of Conversations. Tune in to find out more about Florence Drummond and IWIMRA.

- St George Mining Limited (ASX: SGQ) - Discovering a Major Prize within a New Lithium Province.
Coffee with Samso Episode 160 is with John Prineas, Executive Chair of St George Mining Limited (ASX: SGQ). In this episode with St George Mining Limited , we have John Prineas telling us all about the lithium discovery within their Mt Alexander project. I recently had a few conversations about lithium and I feel that the investing market has not realised that the lithium exploration timeline has just started. The lithium euphoria has only been happening for the last two years. The discovery has been all the easy pickings and more commentary is now in the public domain about the discovery of pegmatites that are basically under cover. Like all the previous commodity boom, the strong demand vs. supply equation will carry the rest of the lithium sector further. My view of the sector is that the demand for lithium will definitely outstrip what the work can provide, literally. The mining of lithium will never catch up with the need for the metal. There is no doubt about this statement. St George Mining is now on the verge of joining the ranks of all the potential players out there with one pointed advantage. It is just 10km and along strike (within the potential mineralisation trend) of the Mt Ida Lithium project which is owned by Red Dirt Metals Limited (ASX: RDT). In this episode, viewers should take note of the potential of the current drilling program. There have been rock chip results showing mineralisation but the drilling results will be the conclusive point. The width mapped on the surface and the rock chip assays should give some indication of the potential. It does not take a genius to realise that there will be pegmatite drilled and there will be number. Where the results will take the project is the unknown. I would start asking the company some serious questions and keep an eye on announcements from the company. Watch this conversation and make a decision to do some serious DYOR. Chapters 00:00 Start 00:20 Introduction 01:27 About St George Mining. 01:58 Discovery having similar geology with Mt Ida. 03:32 How encouraging is the width of pegmatites? 05:13 The drilling program. 05:47 Lithium Exploration is still Young. 07:17 How much of the tenement has been looked at? 08:12 Is it advantageous to be close to Mt Ida? 09:26 Discovering the use of lithium. 11:10 How is your experience with the lithium trend? 13:07 St George Mining’s nickel projects. 15:20 Sharing the funding between two projects. 16:45 What are your thoughts on the market? 18:00 Do you see WA being the dominant player in the lithium space? 21:05 News flow. 22:01 Why St George Mining? 22:41 Conclusion PODCAST Listen to previous Coffee with Samso conversations on Lithium. About John Prineas B.Ec LL.B F Fin Executive Chair John is a founding shareholder and director of the Company.

John has a diverse range of high level experience in finance, mining and corporate governance. About St George Mining Limited (ASX:SGQ) St George Mining Limited is a mining exploration company focused on creating shareholder value through the discovery of world class deposits. At its flagship Mt Alexander Project in Western Australia, St George boasts Australia’s latest nickel-copper sulphide discovery. High-grade nickel-copper-sulphide-PGE mineralisation occurs from just 30m below surface and over a 4.5km strike of the Cathedrals Belt. The discovery continues to grow with ongoing definition drilling delivering further significant intersections of high grade mineralisation including: MAD71 (Stricklands Prospect): 17.45m @ 3.01%Ni, 1.31%Cu, 0.13%Co and 1.68g/t total PGEs from 37.45m including the massive sulphide zones of: 5.3m @ 4.39%Ni, 1.45%Cu, 0.21%Co and 2.09g/t total PGEs from 39.3m; 2.02m @ 5.05%Ni, 2.01%Cu, 0.21%Co and 3.31g/t total PGEs from 50.6m; and 0.5m @ 3.68%Ni, 3.9%Cu, 0.17%Co and 2.68g/t total PGEs from 54.4m. MAD56 (Cathedrals Prospect): 7.5m @ 3.90%Ni, 1.74%Cu, 0.12%Co and 3.32g/t total PGEs from 57.8m including 3.15m @ 6.36%Ni, 2.92%Cu, 0.20%Co and 5.03g/t total PGEs from 61.81m MAD60 (Investigators Prospect): 5.3m @ 4.95%Ni, 2.75%Cu, 0.16%Co and 4.55g/t total PGEs from 157.9m including 3m @ 6.40%Ni, 3.55%Cu, 0.21%Co and 5.25g/t total PGEs from 159.38m This major discovery comes at a time when the electric vehicle (EV) revolution and trend to alternative energy storage systems is gaining momentum. Demand for nickel sulphide – a critical battery metal – is forecast to surge with an upswing in the nickel price already underway. Preliminary metallurgical tests of the massive sulphides at Mt Alexander produced concentrate with 18% nickel and 32% copper with high values for cobalt and PGEs. The excellent exploration results at Mt Alexander build confidence in the resource potential at the Project and support Mt Alexander emerging as a major new nickel sulphide camp in Western Australia. Our other projects – the Paterson and Broadview Projects - are located in exploration hotspots in Western Australia and provide additional value for the Company. Drill core from MAD177 (photo below) which returned assays of: 10.5m @ 4.82% Ni, 1.67% Cu, 0.15% Co and 2.87 g/t total PGEs from 182.5m, including 4m @ 7.53% Ni, 2.47% Cu, 0.23% Co and 3.92 g/t total PGEs from 186m.

I must admit that the Riley's hematite project in Tasmania was never on my radar screen. I wish I had paid more attention to it, as the iron ore price is at an all-time high and what I am seeing is, the economic fundamentals of this sector are looking good for the coming years. There are news that there will be a pull back next year, but I am sticking my neck out here in saying that I do not really see that happening. The world economy has had a twelve-month hibernation and as we are gradually coming out of this pandemic, I see economic growth moving rather well. Today, Andrew Radonjic shares with us: The latest update on Riley Sustained Iron ore Price When the first shipment will be What the revenue from the mining operation will mean for Venture Minerals Share to Grow: Your Bonus This is a good time to download the first Ebook (FREE) from Samso as it is all about VMS (Volcanogenic Massive Sulfides).

PODCAST About Andrew Radonjic Mr. Radonjic is a geologist and mineral economist with over 25 years of experience in mining and exploration, with a specific focus on gold and nickel in the Eastern Goldfields of Western Australia. Mr. Radonjic began his career at the Agnew Nickel Mine before spending over 15 years in the Paddington, Mount Pleasant and Lady Bountiful Extended operations north of Kalgoorlie. He has fulfilled a variety of senior roles which gave rise to three gold discoveries, totalling in excess of 3 million ounces in resources and the development of over 1 million ounces. About Venture Minerals Limited Venture Minerals Limited is currently exploring in Western Australia for Copper-Lead-Zinc at the Thor Prospect, Nickel-Cobalt at the Pingaring Project (adjacent and along strike to the Quicksilver Nickel-Cobalt discovery), Nickel-Copper (new target) at the Odin Prospect and Nickel-Copper-Cobalt at the Caesar Project. Recently the maiden drilling program at Thor intersected massive sulfides confirming the Copper-Lead-Zinc target is a 20 a kilometre VMS style system. Thor is now a top priority target for Venture moving forward. The Company's initial focus was on realising the full economic potential of the Mount Lindsay Tin-Tungsten Deposit in North-West Tasmania. The Company has already defined one of the world's largest undeveloped tin deposits and has completed a Feasibility Study on Mount Lindsay. The emergence of tin as the metal most impacted by new technology through its use in Electric Vehicles has refocused Venture’s approach to developing this asset and an underground scoping study is currently underway.

- Discovery Time: Galileo drilling at their Fraser Range Nickel Project - Rooster Talk Episode 21
Galileo Mining is a resources company listed on the Australian Securities Exchange (ASX) under the code GAL and is exploring for base metals in south-east Western Australia. The company has a 100% ownership of its Norseman Project and has Joint Ventures with the Creasy Group over highly prospective tenements in the Fraser Range. The Norseman Project is located adjacent to the regional town of Norseman in an infrastructure-rich area of Western Australia. A bitumen highway runs parallel to the project area and is less than 10km from the Company’s current JORC cobalt-nickel resources. The Norseman Project includes numerous areas with potential for further cobalt discoveries as well as additional nickel and copper prospects. The Fraser Range Project covers two zones of the extensive Fraser Range geological belt. The Fraser Range is known for the world-class Nova nickel-copper-cobalt mine discovered by Sirius Resources in 2012. Galileo’s northern Fraser Range tenement is 80km from the operating Nova mine while the southern tenements are just 30km from the mine. Galileo is targeting Nova style nickel-copper-cobalt mineralisation in the Fraser Range and has a deep level of experience in the region. The company was originally privately owned by renowned prospector Mr Mark Creasy, and Galileo Managing Director Mr Brad Underwood spent eight years as General Manager of the Creasy Group’s exploration at the Fraser Range and at Norseman. Galileo Mining listed on the ASX in May 2018, raising $15 million in IPO funding. Mr Creasy continues to be the largest shareholder, controlling approximately 31 percent of the company. ASX-listed miner Independence Group (ASX: IGO) and Mineral Resources’ founder Chris Ellison are included within the Company’s top five largest shareholders. Galileo Key Milestones: 2003 – Registered as a private company wholly-owned by Mark Creasy 2004 – Acquired the Norseman project 2006 – Initial drilling conducted at Norseman 2017 – Maiden JORC Resource completed at Norseman 2018 – Acquired interest in the Fraser Range project 2018 – Launched on the ASX as a public company Since our first Coffee with Samso in May, Galileo has been very active in preparing for this moment of drilling targets. We speak of the "Truth Machine" being what all projects need or fear. In this case, I do believe that this will bring exciting times for shareholders. Brad Underwood has been preparing these projects with desktop surveys, geochemistry and geophysics. The obvious next step is to drill the targets identified. Brad tells us that there will be coming news for the next 6 months. Brad tells us about how the geophysics is clean, meaning that the country rocks are not compromising the results. Since preparing for the first Coffee with Samso with Brad , I have come to appreciate how unique this area is compared to your normal nickel project. When Brad talked about the unique metal composition, more copper, I think there are more discoveries left in the Fraser Range. I hope you find it an interesting object lesson in nickel exploration and its investment potential. PODCAST About Brad Underwood Brad Underwood is the Chairman and Managing Director of Galileo Mining. Mr Underwood is a geologist with over 18 years’ experience in exploration, prospecting and mining. He has been involved in copper, gold, nickel and cobalt discoveries and the development of numerous prospects over a variety of commodities.

- The Story of Halloysite - is it all just Hype or Something More.....
The mineral resources investing community in the Australian Stock Exchange (ASX) probably first heard of Halloysite when Andromeda Metals Limited (ASX: ADN) made news of their deposit in South Australia. I for one, certainly only heard of the term when I looked at Andromeda. Did you know that up until 2005, the main use of halloysite was as an alternative raw material to kaolinite for ceramics? Today, there is an exponential increase in research aimed at halloysite Nanotubes (HNTs). The use of halloysite is almost synonymous to crying out: "Oil that is, Black gold, Texas Tea" - [For those that remember] As we move into 2022, there is only one other company, Suvo Strategic Minerals Limited (ASX: SUV), promoting the same story. It is a unique mineral and there is still a lot of misinformation and misunderstanding about the commodity and its potential uses. To add to the list of "issues" there is also a lot of mistrust of the potential use of the mineral. Halloysite Halloysite was named by Berthier in recognition of Belgium geologist J.J. d’Omalius d’Halloy who, in the early 19th century, collected samples of waxy, white clay at Angleur, Liége, which Berthier (1826) later analysed and described [3]. Halloysite is a 1:1 dioctahedral clay mineral that has been studied widely for applications in nanotechnology and as a mineral exploration guide for recognising regolith-hosted heavy rare earth element (HREE) deposits. [1] Figure 1: (a) Straight, regular halloysite microtubles from Camel Lake. (b) Halloysite crystal morphology and atomic structure. (Photo 414524) [2] According to [2], Halloysite is a relatively common mineral that often crystallises together with kaolinite; the two polymorphs of kaolin are not easily separated. Deposits suitable for commercial development are, however, comparatively rare and occur either as relatively pure masses of halloysite (e.g. Dragon Mine, Utah; Camel Lake) or as large, lower-grade sources from which halloysite can be readily separated (e.g. Matauri Bay deposits, New Zealand). Figure 2: Geological setting of halloysite deposits formed by acid groundwater at the Camel Lake site, near Maralinga, South Australia.[2] As a geologist, I will say upfront, I know very little about halloysite and trying to explain the geological process is impossible for me. Doing research and trying to understand and then trying to summarise it is not an easy task. So there is going to be a lot of paraphrasing happening here. Who is mining Halloysite? As far as I know, there are very few people mining halloysite. According to my research, or what I have found, there are two "world-class" locations - Dragon Mine in Tinitc, Utah (USA) and the Matauri Bay deposit in Northland, New Zealand. 1) Matauri Bay halloysite deposit, Northland, New Zealand. According to [4], halloysite clay deposits have been mined and processed in the Keriker-Matauri bay area of Northland since the late 1940s. Since the mid 1970s, this has been the dominant continuous supplier of halloysite worldwide, averaging around 20,000 tonnes per annum (tpa). Figure 3: The very pure halloysite clay dug at Northland’s Matauri Bay is exceptionally white and bright. It is exported for use in high-quality materials such as porcelain, bone china and technical ceramics. [7] The operation was acquired in 2000 by Imerys from former owners New Zealand China Clays Ltd. Imerys Tableware NZ Ltd currently mines raw clay from open pit mines developed in the Matauri Bay and nearby Mahimahi rhyolite domes (Fig. 4). The raw clay contains around 50% halloysite, 50% silica minerals (quartz, cristobalite, tridymite, amorphous silica), and minor feldspar. Figure 4: Geological map of the Kerikeri – Matauri Bay region of North Island New Zealand (derived from Web Map (GNS Science, 2013) [5]) showing rhyolite domes and halloysite deposits, with sketch west-east section through the Matauri Bay halloysite deposit (after Brathwaite et al. (2012)) 2) Dragon Mine [8] Dragon mine is located in the Tintic District of north central Utah, some 60 miles southwest of Salt Lake City. The geology and details of alteration and mineralization at the Dragon mine are well described by several authors and the references can be found in [8]. The host rocks are Upper Cambrian Ajax Dolomite and Opex Formation with underlying Middle Cole Canyon Dolomite and Tintic Quartzite (Fig. 5). There are two main clay bodies at the Dragon mine – West and East as shown in Fig. 5. Dragon was originally an iron ore mine and subsequent mining of halloysite was mainly from underground during 1947– 1976 with 1.35 million tons mined by Filtrol. Figure 5: Geological section, approximately west–east, through the Dragon mine, Tintic mining district, Utah, showing the distribution of halloysite ore zones – redrawn from Kildale & Thomas (1957) and Morris (1985). Historical Article highlighting Resources at Dragon mine. Halloysite was extracted using a square-set method (5.2 × 6.0 × 7.8 ft) and hand-drills, and it was transported to the surface via a shaft and then loaded onto a lorry, which delivered raw clay to the Filtrol plant in Salt Lake City for processing into a fluid cracking catalyst (FCC) for the petroleum industry. Other players Wilson and Keeling 2016 [8] has Table 1 below which shows some of the halloysite sites around the world. Their work is pretty good in giving an idea of what is around. However, there have been several new players since Suvo Minerals identified halloysite on their Pittong Operations as well. Table 1: Some halloysite and mixed halloysite-clay deposits.[8] There is a report in 2021 of a pegmatite in Brazil which has tubular halloysite and HREE (Heavy Rare Earth Elements), so discoveries are being made. As halloysite is chemically and physically different from normal kaolin-kaolinite, the identification of halloysite will happen more commonly. However, as you see how the categorisation/grading of these "clays" become clearer, the economic implication will cause many halloysite deposits uneconomical and hence, not important. Grading Kaolin - Halloysite The way industrial clays are considered to have technical and economic qualities is solved by the process of categorisation. In the market, we hear of the term "white brightness" to classify the quality of halloysites. In an article by Harvey and Keeling 2001 [7], there are four categories. Category 1: clays of high quality requiring major capital investment to supply large tonnage, international markets. Produced in Georgia (USA), Conrnwall (UK) and the Amazon Basin in Brazil. Category 2: unique specialty clays for which advanced technologies are required to produce small tonnages for niche markets. Clay deposits in this category are typically of high purity and are found in somewhat uncommon geological settings. Minerals such as Hectorite and Bentonite are common types within this category. Category 3: moderate quality clays requiring relatively low technologies, to supply predominantly local markets. Category 4: clays of low quality requiring little or no processing. Harvey and Keeling 2001 concluded by noting that Categories 1 and 2 clay projects are of a higher quality which require extended development times (from green-field to investment decisions) and significant pre-development capital investment. On the other hand, the development of Categories 3 and 4 clays requires shorter times and lower levels of capital investment. According to the article, Category 2 is where halloysite sits. Interestingly, the article mentions the Maauri and the Poochera deposits as type areas. Figure 6: Location of Australian and New Zealand clay deposits. [7] There are no known hectorite in either Australia or New Zealand, although the geological setting of the North Island of New Zealand is in many ways similar to that of Nevada. Both Nevada and the central North Island of New Zealand have extensive areas of hydrothermally altered acid to basic volcanic rocks. Interestingly, my previous understanding of Australian clay deposits (Figure 6) was that they were all uneconomic. According to this paper [7], I was not far off the mark. The majority of the Australian clay deposits sits in Category 3 and 4, which are the lower value. These deposits are largely deemed uneconomical due to their logistics and location to market. The Significance of Halloysite While doing research on this Insight, what is very clear to me is that there is a lot of momentum in this sector. Recently I did a Coffee with Samso with James Marsh, the managing Director of Andromeda Metals - Andromeda Metals Limited (ASX:ADN) - The Real Story. - where we talked about the misunderstanding of the strategy of the company. In that Coffee with Samso, our discussion centred on the downstream part of the story which is the unique part of the whole halloysite story. It is, in fact, the emerging part of the Kaolin-Kaolinite-Halloysite sector. Figure 7: The number of scientific papers written with each year up to 2015 according to the appearance of (a) halloysite (diamonds) or (b) halloysite nanotubes (HNTs) in the Article Title, Abstract or Keywords (both sourced from Scopus© database) and (c) numbers of patents filed per year with halloysite in Article Title or Abstract (source Espacenet) [10] The chart in Figure 7 is a great way of showing the influx of research in the halloysite sector. I remember James Marsh telling me about the thousands of papers that have been written about this subject and the myriad of potential downstream products. When I first had a conversation with Andromeda way back in 2019, I had no idea about the downstream process. I actually thought that it was more of a dream than a potential reality. In the last Coffee with Samso with James, it was great that we put some layman's reality into the whole process. I feel this is an important for the halloysite message because there is a lot of confusion in the market. The confusion is born out of a lack of understanding of the downstream process and the myriad of potential products. What Does All This Mean? Players such as Andromeda and Suvo Strategic Minerals are in a space that is evolving. The emerging new "Industrial Revolution" that I spoke of in the latest Samso Insight - Expectations for the Mineral Resource Industry in 2022 - Green Energy and No Emission. - is going to drive more need for the humble Kaolin. At the moment, in my opinion, the jury is still out in terms of the products from halloysite. I agree that there are many products which are at a pilot stage, like Andromeda, but the success or lack of is unknown. Science shows that through a step process of test and pilot plants, this normally ends well but there is no ´sure thing´ concept here. One of the most updated places to get information on the downstream products would have to be the Andromeda Metals website. They have been the most active in promoting their vertical integration business model. Table 2: Some present and future uses and applications for halloysite. [8]. The way Andromeda has separated their products is interesting. I think if we take the categorization observed in the paper by [7], I would fit them as follows: Kaolin (Category 3 and 4), Halloysite Kaolin (Category 2 and 3) High Purity Alumina (Category 1 and 2) Suvo Strategic Minerals is continuing to develop their Pittong operations and recently announced some upgrade in their Kaolin grades - Further High Grade Halloysite at Trawalla, Grades Up to 32.4% - which will be good for the company. However, I actually think that if you can get simple kaolin to the market, that is a great achievement by itself. The Kaolin space is so active now that I think having an operation like Pittong is some of the advantage that Suvo has over their competitors. Like all mineral projects, an operation that is up and running is a lot better than just talking about it.
