WYX boosts bauxite position in WA
Special Report: Western Yilgarn has expanded its bauxite footprint within WA's Darling Range bauxite mineral field with the acquisition of the Cardea 3 project.
Western Yilgarn expands WA bauxite portfolio with Cardea 3 acquisition
Historical drilling has returned high-grade alumina exceeding that mined at the nearby Worsley Alumina Operations
Cardea 3 is near major highway and multi-user railway
It follows closely on the WA Department of Energy, Mines, Industry Regulation and Safety awarding exploration licences E70/6702 and E70/6703 – the Cardea 1 and 2 project areas – in late May.
Western Yilgarn (ASX:WYX) paid the vendor a $5000 cash deposit on executing the terms sheet and will make a further cash payment of $20,000 and issue $25,000 worth of shares at an issue price equal to the 20-day volume weighted average price once the exploration licence application is granted.
Cardea 3 has seen some historical exploration with 422 vacuum drill holes completed to date. Of these, 139 have been analysed for available alumina and reactive silica.
Results from this work indicate that high-grade bauxite is present with available alumina – the portion of Ai2O3 that can be extracted under Bayer process conditions – exceeding 34.5% and reactive silica content of 3.14%.
This compares very favourably with the average mining grades of 28.7% available alumina and 1.9% reactive silica at South32's (ASX:S32) nearby Worsley Alumina Operations.
Surface bauxite mineralisation has also been defined over a 3km by 1km area with a laterite profile typical of Darling Range bauxite deposits.
'We are extremely pleased with the acquisition of the Cardea 3 project, which provides significant scalability and strong potential to further increase both bauxite tonnage and grade through continued exploration—particularly in the western portion of the exploration licence area,' non-executive director Pedro Kastellorizos said.
'The project's proximity to a multi-user railway, within trucking distance, is a key logistical advantage, especially in the current market environment of record alumina and bauxite prices.'

Cardea 3 project
Cardea 3 sits within the Darling Scarp Bauxite Province – a key bauxite region centred on Pinjarra, Waroona and Worsley, which are major aluminium production hubs about 80km to 150km south of Perth.
It is about 17.5km east of the company's Julimar West bauxite project and can be accessed from Perth via the Great Northern Highway and is well supported by the Perth Kalgoorlie Railway line to the south of the project area.
Results from the vacuum drilling have indicated that the highest grade zones – exceeding 40% Ai2O3 - are concentrated in the central and southern portions of the exploration licence area.
WYX added that data to date indicated that alumina and reactive silica for this deposit may be comparable to nearby bauxite mining operations such as the Worsley Alumina Operations.
Surface and drilling geochemistry, along with the interpreted geophysics has highlighted multiple targets proximal to the west and south of the current tenure areas.
Regional mapping and interpretation of the Western Australia Geological Survey has delineated laterite and pisolitic gravels in which the bauxite occurs.
These areas will be systematically targeted once the company starts first pass exploration.

Rio stays the course on lithium as it looks to rejuvenate iron ore business
Outgoing Rio Tinto boss Jakob Stausholm says Rio remains committed to its lithium strategy Mining giant just opened newest iron ore operation in WA's Pilbara CEO denies being nudged by board as he says company leaders are aligned on ESG and operational improvements The head of the world's second biggest miner Rio Tinto (ASX:RIO) says its board remains aligned on a counter-cyclical push into lithium as CEO Jakob Stausholm denied speculation that friction with the company's board was behind his decision to resign this year. Stausholm's near five year tenure at Rio followed the destruction of the Juukan Gorge rock cave in the Pilbara under his predecessor JS Jacques, an act that led to Jacques' resignation and steered the $150bn miner on a course to prioritise its ESG commitments. In that time, its new investments have focused in two areas, replacement mines to address declining iron ore quality at its flagship Pilbara operations and M&A to become one of the world's largest lithium producers. The latter has come under the microscope amid Stausholm's surprise exit, with lithium prices crashing to four year lows after Rio's entry as a producer via its $10 billion takeover of Argentine brine producer Allkem. Speaking at the opening of Rio's first of five major replacement iron ore mines due in the next five years – the 25Mtpa Western Range with Chinese steel giant Baowu near Paraburdoo – Stausholm said Rio's board remained aligned on its lithium strategy. "The lithium strategy we are absolutely aligned about in the whole board. This is a next pillar," he said. "Think about it like some visionary people 50-60 years ago said Rio Tinto should go into iron ore. "We need to think about the future to the next decade and the next decade. And we are lucky that we have built now a portfolio of outstanding brine resources in Argentina, in Chile. " It's going to complement our – what I would call signature – business here of iron ore for the future." Grade control Under Stausholm, Rio has cleared a number of social licence hurdles in its WA heartland culminating in an agreement this week with the PKKP group, the very Traditional Owner group devastated by the 2020 demolition of Juukan Gorge. It will be a key stakeholder for the US$1.8bn Brockman Syncline 1, the next replacement mine approved for the ~40Mtpa Brockman hub, one of a number of developments that will cost Rio in the order of US$13bn to deliver in the coming years. Western Range is a milestone in that it marks the first new operation delivered by Rio's iron ore division since Juukan Gorge (its Gudai-Darri mine was under construction at the time), and the first to a mine plan co-designed with the TO group, the Yinhawangka People. But Rio's iron ore division has been, quite literally, degrading. 2023 and 2024 marked long time highs for iron ore production at 331.8Mt and 328.6Mt, making Rio the largest exporter of hematite iron ore in the world. But costs have been escalating at a faster rate – on reported numbers at least – than its peers BHP and Fortescue. While BHP and FMG reported C1 cash costs of US$17.50/t and US$19.17/wmt in the first half of FY2025, Rio's unit cash costs came in at US$23/t in CY24. Its 2025 numbers will likely be higher at a guided range of US$23-24.50/t. And while 62% Fe Singapore iron ore futures are sitting at US$95.55/t, Rio's realisation to the benchmark price has been slipping. It notified customers that during the September quarter the spec grade for its Pilbara Blend product will drop. Fastmarkets this week introduced a 61% Fe Index to reflect the lower quality product Pilbara miners are now shipping. It will likely take until the end of this decade, when Rio delivers the higher grade Rhodes Ridge mine, for its grade to recover. Speaking at the Western Range opening, Stausholm denied any rift with new chair Dominic Barton, nor that the miner's focus on ESG under his leadership had clouded its dedication to operating performance. "We are absolutely aligned. It's very important to say we in the management team and the whole board (are) absolutely aligned around the values of Rio Tinto about pursuing the four objectives, about our strategy and the strategic choices and about the assessment of our performance," Stausholm said. "So there is no disalignment. "We are absolutely aligned. It's very important to say we in the management team and the whole board (are) absolutely aligned around the values of Rio Tinto about pursuing the four objectives, about our strategy and the strategic choices and about the assessment of our performance," Stausholm said. "So there is no disalignment. "If you look at my statements at the full year results, I said exactly the same thing because we have under the four objectives, made a lot of progress on rebuilding trust in the company, working towards impeccable ESG credentials, improving how we execute projects. " This project is an example. This project is on time, on schedule. "We still have the potential to do in the best operator, our safe production system is really working. So I said that at the full year, and my chairman repeated that a couple of weeks ago." Steel on top The official opening of Western Range marked a second major development in the relationship between Rio and China's top steel producer Baowu in the Pilbara after the development of Eastern Range in the early 2000s. It followed Rio's landmark first deal with China's Sinosteel at the nearby Channar JV almost 40 years ago. Australia now ships over 900Mt of iron ore a year, the vast bulk of it (around 80%) to China, the world's largest steel producer. But as new, high quality ore sources are developed overseas – notably the high grade 120Mtpa Simandou project in Guinea in which both Rio and Baowu are invested – question marks are hovering over the centrality of the long-established "conveyor belt" between the Pilbara and Beijing to the steel supply chain. FMG chairman Andrew Forrest notably sounded the alarm in recent months over the emergence of new competitors to WA who could eat its golden goose. He is lobbying hard for the establishment of a domestic green iron industry. But Rio remains confident in the role Australian iron ore will play in the future, even in a decarbonising world where green steel technologies – not suited to low and mid-grade ores produced in the Pilbara – could dominate. "It is for us as companies to make sure that the Pilbara ore remains relevant," Stausholm said. "And how do we do that? We do that in partnerships like you see today with Baowu, working on how can we decarbonise the supply chain. " If you find the right solutions and we will, then Pilbara will be the source for many, many decades to come." Stausholm's departure comes as BHP is also rumoured to be looking for a new CEO to replace Mike Henry, and has a number of internal Rio candidates reputedly jostling for position, among them chief commercial officer Bold Baatar and local favourite Simon Trott, who helped open Western Range on Friday and runs the major's iron ore division out of its Perth office.

Superannuation wealth tax ‘a threat' to funding of new unicorns as Escalante moves to mop up VGW
The Federal Government's proposed wealth tax on superannuation has been described as a threat to the emergence of unicorns such as Laurence Escalante's WA-based gaming group Virtual Gaming Worlds. With many investors funding plays such as VGW from their self-managed super funds, the earnings hit on super balances over $3 million is seen potentially depriving start-ups of a key source of development capital. Mr Escalante used millions of dollars raised from hundreds of small and high-net worth backers to build VGW into one of Australia's fastest-growing and most profitable private companies. On Monday, the former financial planner announced a $960m bid to take full ownership of VGW by buying out the 30 per cent of the public, unlisted company he does not own at $5.05 a share from some 700 minority shareholders. One of his early supporters, an investor who is sitting on tens of millions of dollars of profit on VGW shares bought for less than 10 cents apiece, said the Government was 'off the mark' with its proposed move on wealthy superannuants. He and other big minority investors in VGW are mainly invested in the group via their self-managed super funds. 'This Government wants to tax quite heavily the people in the super funds, and that's where these small companies get started,' said the investor, who asked not to be identified. 'There won't be as much money available for start-ups.' Mr Escalante's proposed buyout, launched through his Lance East family office, comes as VGW confronts a major threat to its lucrative operating model from a US regulatory crackdown that is reining in its runaway profits. The group has raked in billions of dollars by using loopholes in US laws banning internet gambling to deliver online 'social' casinos and poker machine games such as Chumba Casino, LuckyLand slots and Global Poker. Under its sweepstakes model, customers buy virtual gold coins that allow them to play VGW's games but have no outside value. However, buyers of most gold coin packages also get bonus 'sweeps coins', which as well as being used to play the games are redeemable for cash in most of the US and Canada. US States are now moving against the group, claiming the games are illegal because they are generating cash winnings for players. Since December, VGW has quit Nevada and Delaware, and flagged its withdrawal from New York, in the face of the pushback. The regulatory crackdown is already hurting earnings, with VGW warning of a 15 per cent hit to its second-half profit. Mr Escalante's opulent lifestyle — he has translated his wealth into a private jet, super cars, luxury boats and swanky properties — and showy and sometimes angry social media posts had already raised doubts about whether he could win over the big institutional shareholders needed to support a stock market listing in the US or Australia. But it is the threat to what has been an enormously successful operating model that has most likely finished off lingering hopes of a float for investors who have been limited to selling stock via an illiquid over-the-counter trading platform. 'It's the model ... the likelihood of regulatory action, which are we starting to see,' a prominent Perth businessman said. While Mr Escalante's 'behaviour and lifestyle doesn't help', despite global stock markets being awash with such 'characters', a listing would have more chance with a 'safer and less vulnerable business model', the businessman said. There is no doubt that Mr Escalante, who founded VGW as a 28-year-old in 2010, has delivered in spades for his investors. The company paid its first dividend — a modest $2.8 million — in early 2019 off the back of a $19.8m profit and $179m of revenue for the December half-year in 2018. COVID-19 lit a fire under the business as uptake of its games in the US soared during lockdowns. Over the past four years, VGW has returned more than $1.3b to its shareholders, with Mr Escalante pocketing the lion's share due to his majority ownership. He will receive a further $200m from the $286m of interim and special dividends set to be paid for the 2025 financial year. VGW's two independent directors have determined that the offer price, which will be reduced by the dividends, recognises the company's value 'after taking into account its medium and longer-term potential and the ongoing risks relating to VGW's business and operating environment'. Mr Escalante's offer was endorsed after an earlier pitch of $3.50 of $4 a share was rejected as too low. However, it still may not be enough to get the buyout across the line, with some long-standing shareholders still reckoning VGW is worth more and disputing the inclusion of the proposed dividends in the offer price. 'A few of the shareholders who have got pretty good holdings feel as if it's an unreasonable offer, they feel as if it should be more,' the VGW shareholder said. The buyout documents are expected to be sent to shareholders by early July, with a vote to be called in August. Mr Escalante was not available for comment this week. Disclosing the buyout offer on Monday, he said it represented 'an efficient opportunity to allow those shareholders looking to monetise their investment for cash to do so'.

Barry FitzGerald: Katanning ticks all the boxes for an Ausgold re-rate
'Garimpeiro' columnist Barry FitzGerald has covered the resources industry for 35 years. Now he's sharing the benefits of his experience with Stockhead readers. After its dramatic rise in the opening months of the year to record levels, the Aussie gold price has settled into a bit of a groove around the $5,200/oz level. Nothing wrong with that. It's a fantastic price and delivers fat margins to even our highest cost gold mines. And it is not to suggest that gold can't take off again and set new highs or fall significantly for that matter. The observation is that for the last six weeks or so the Aussie price has been as steady as it could be in these turbulent times. It means that share prices of ASX-listed gold producers and developers have also gone into a sideways trading pattern. Need to differentiate So more than has been the case in recent times when gold took off to record levels, the producers and developers now need to differentiate themselves from the pack with strong newsflow of the re-rating inducing type. It means that if the gold price continues to trade sideways, the stock involved has a reason to go higher. Alternatively, if the gold price heads south, the damage to the stock could be more limited than it would have been otherwise. Taking all that on board, Garimpeiro had a look at his calendar during the week to find which of the gold producers/developers have re-rating event(s) on the horizon. Ausgold stands out Ausgold (ASX:AUC) stood out for the pending release this month of a definitive feasibility study (DFS) into the development of its Katanning gold project, a three-hour drive from Perth in WA's southwest Yilgarn region. Katanning is one of the biggest undeveloped gold deposits in the country at 3.04 million ounces and has previously been scoped as having the potential to produce 136,000 ounces annually from open-cut ore sources for more than 10 years. All-in sustaining costs were put at $A1,549 and preproduction capital costs weighed in at just under $300m. But those are 2023 figures and things will have changed, including the reserve component of the resource thanks to infill drilling work. Gold prices have increased dramatically since those 2023 figures but so have construction costs. Having said that, the expectation is that the DFS will confirm Katanning as a very robust project with a super quick capex payback capability. Take that and the scale of the project – production in the early years will be higher still because initial higher grade ores - and Ausgold's $240 million market cap at 67c share looks to be on the mean side of things. The company has the lowest resource ounce valuation metric of its peer group for no apparent reason, except perhaps the project has been in the works since 2010 under Ausgold ownership. So the story of the resource growth since, and the pending release of the DFS leading into a development decision by year end, has been overlooked to a large degree by the market on a fatigue basis alone. Katanning momentum Momentum for Katanning is now the order of the day under John Dorward, Ausgold's executive chairman who arrived on the scene in May last year. A can-do sort of guy, Dorward was the former president and CEO of TSX-listed Roxgold, a West African gold group acquired by fellow Canadian Fortuna Silver Mines in an all-scrip deal worth $US884 million in 2021. Two weeks in the job at Ausgold and Dorward put Katanning on the development pathway by pulling in $38 million in equity, including $1m from his own pocket. That is being spent getting to the DFS stage and on a three-pronged strategy of establishing a bigger mining reserve component in the mineral resource estimate, extending the scale of the resource and making regional gold discoveries. Morgans' 94c target Morgans' veteran analyst Chris Brown has a 12-month price target on the stock of 94c. 'Our expectation is that delivery of a DFS broadly confirming or improving on the preliminary feasibility study, and employing a higher gold price, should prove positive for the share price,' Brown said. He also flagged that a final investment decision on a project development – expected by the end of the year - should also prove positive depending on the terms of the project's financing package. ''Our valuation will likely lift with the delivery of the DFS, and again when the final investment decision is taken,'' Brown said.
