Yari Minerals (ASX:YAR)
A prime mover among ASX small caps stock was Yari Minerals after diversifying its Australian asset base to include the Rolleston South coal project in Queensland, an advanced play with a resource and near-term development potential.
The Bowen Basin project covers 272km2 and has a JORC inferred resource of 78.9Mt of high calorific value coal with substantial exploration upside and being in the vicinity of Glencore and Peabody mines, infrastructure, including sealed roads and railway, is top-notch.
Investors liked what they saw and shares were quickly off the line, charging 240% higher to 1.7c, a new 12-month high with more than 100m changing hands, before slowing to 0.8c at the close.
The company has agreed to acquire Resource Chain Pty Ltd, the 100% legal and beneficial owner of the Rolleston South project, and has executed a conditional binding share purchase agreement.
Consideration consists of upfront and deferred components, including a total of 119,560,669 Yari shares for a 19.9% stake in the company and an additional 86,045,322 performance rights with a vesting criterion on declaration of a JORC inferred coal resource greater than 100Mt.
Completion of the acquisition is subject to the company satisfactorily completing due diligence on the project and Resource Chain.
Previous exploration delineated six coal seams, which are yet to be fully developed, underpinning Rolleston South's exploration upside.
Historical laboratory analysis re-confirmed previous coal quality results indicating that it is suitable for a high grade, low ash and high energy coal.
The washed coal results are between 24.33 and 27.98Mj/kg and can support an export thermal product, with evidence that semi-soft metallurgical coal products with a swell of 2.5 to 4 could also be produced.
Yari's initial focus is to finalise key targets for an inaugural drilling campaign and produce a semi-soft metallurgical coal product.
'The acquisition of the Rolleston South Coal Project meets the stringent investment criteria set by Yari to identify and acquire a JORC compliant mineral resource in a Tier 1 jurisdiction, that is capable of rapid advance to resource growth and future development scenarios,' managing director Anthony Italiano said.
'On completion, Yari will commence a review of the resource model to incorporate additional data from coal seam gas wells whilst concurrently planning to commence a drilling program to complete this year to both grow the mineral resource outside the current resource envelope and complete infill drilling to increase the resource categorisation.'
Yari Minerals (ASX:YAR) also owns 100% of the Pilbara Projects, which comprise about 980km2 in five granted exploration licences in WA's Pilbara region.
These projects are highly prospective for lithium and are near two of the world's largest hard rock lithium deposits/mines (ASX:PLS – Pilgangoora and ASX:MIN – Wodgina) and other deposits and occurrences near Marble Bar (ASX:GL1 Archer project).
Medallion Metals (ASX:MM8)
Growth potential at the Ravensthorpe gold project of Medallion Metals in WA has been enhanced by strong results from RC drilling and shares reached 26c, a move of 10.64% on the previous close.
Two extensional holes down plunge of the Gem lode within the Kundip Mining Centre have extended the high-grade lode at Gem deposit by about 80m past the resource boundary.
Best results were:
6m at 4.6g/t gold, 1% copper and 9.1g/t silver (6.3g/t AuEq) from 343m including 2m at 11.2g/t Au, 2.4% Cu and 19.5g/t Ag (15.3g/t AuEq)from 345m;
3m at 6.8g/t Au, 0.6% Cu and 5.5g/t Ag (7.8g/t AuEq) from 346m; and
2m at 3.9g/t Au, 0.6% Cu and 2.9g/t Ag (4.9g/t AuEq) from 355m.
These intersections are ~60m beyond the limits of the current mine plan, 40-80m beyond the current inferred resource boundary and 40-100m down plunge from drilling that determines the resource estimate.
They confirm the potential to increase the resource of 5.6Mt at 4.3g/t Au and 0.6% Cu for contained gold of 770,000oz Au and copper of 36,000t.
Results also support the technical team's belief that the 6.7m semi-massive to massive sulphide intersections reported in diamond drilling on April 3, 2025, represent a newly identified and separate sulphide occurrence to the Gem main lode zone.
'These results are extremely positive and have important implications for the project as the business looks toward near-term development,' managing director Paul Bennett said.
'Project economics are significantly levered to mine life extensions and these results demonstrate that above cut-off grade mineralisation at mineable widths extends up to 60 metres down plunge from the current limits of the mine plan.
'This builds further confidence that mine life can be increased by extensions to the known lodes as well as through delineation of new lodes at depth with ongoing drilling.
'We maintain we are just scratching the surface of this significant mineralised system as continued investment delivers for our shareholders.'
The two holes are part of a broader 17,000m drill program designed to grow the high-grade sulphide underground resource at KMC in size and confidence.
About 15,000m of combined diamond and RC drilling has been completed under the program, which will inform a resource update underpinning a feasibility study assessing the technical and commercial viability of mining Ravensthorpe ore at a modified Cosmic Boy process plant.
In August 2024 MM8 entered an exclusivity agreement with IGO to negotiate the acquisition of the Forrestania Nickel Operation, which includes the Cosmic Boy plant and associated infrastructure.
MM8 will complete the enlarged drill program ahead of completing a Ravensthorpe resource update in June 2025 and an updated resource for Harbour View in July.
The updated resources will form the basis of a feasibility study that will inform the board's decision to progress with a development.
Aurum Resources (ASX:AUE)
After scoring $35.6m in a private placement to boost its diamond drilling fleet to 10 rigs in the quest to increase its 2.5Moz West African gold resources, Aurum Resources reached 44.5c, a lift of 23.62%.
The company has fielded firm commitments from the Lundin Family, Montage Gold and Zhaojin Mining for a private placement of 100 million ordinary shares at A$0.356 per share, equal to Aurum's five-day volume-weighted average price (VWAP) from April 28 to May 2, 2025.
It comprises cash investments of $23.89 million and $11.71 million by way of the issue of fully paid common shares in TSX-listed Montage Gold Corp, which will hold 9.9% of AUE.
Lundin Family and associates have invested $11.71m to hold 9.9% of AUE and Zhaojin Capital Ltd, a wholly owned subsidiary of Zhaojin Mining Industry Co Ltd, has invested $8.19 million cash to hold 8.5%.
The balance was issued to various professional investors and parties unrelated to the company.
Aurum will use the cash component to accelerate resource definition drilling at Boundiali project and exploration drilling at its newly acquired Napié project, both in north Côte d'Ivoire, including the purchase of an additional two diamond drill rigs.
It will also conduct a PFS and DFS for the Boundiali project, progress a mining exploitation licence application and approvals, and complete environmental and social impact study and ESIA approval.
Montage Gold is focused on becoming a premier African gold producer, with its flagship 90%-owned Koné project, south of Aurum's Boundiali project at the forefront.
Based on an updated feasibility study published in 2024, Koné has an estimated 16-year mine life and annual production of +300,000oz of gold over the first eight years and is expected to enter production in Q2-2027.
'We are very encouraged by the strong support from highly regarded strategic investors, which is a true endorsement of the quality of our two gold projects in Côte d'Ivoire and recognition of our practical, cost effective and efficient exploration approach and fast-tracking project development strategy,' Aurum's managing director Dr Caigen Wang said.
'I also extend our thanks to existing shareholders for their ongoing and long-term support.'
Ark Mines (ASX:AHK)
Shares lifted 14.71% to 19.5c after Ark Mines validated historical results with wet season sampling at Pluton gold project in north Queensland returning rock chip assays up at 25g/t gold and 34g/t silver.
The rock chip sampling, which returned average grades of 3.4g/t gold and 7.1g/t silver, also featured good pathfinder correlations, which is expected to lead to further exploration.
Adding further interest, the structural relationships with prospective lithologies show potential to extend the target area.
'What's not to love about 25 grams per tonne? Even the 3 grams per tonne sample average is very nice,' executive director Ben Emergy said.
'There's a lot of work still to be done at Pluton and we don't want it to distract from Sandy Mitchell and the great story Ark is developing there but Pluton has potential that we can't ignore and makes a good wet season field option.'
Ark Mines carried out initial rock chip sampling at Pluton during the wet season hiatus of the intensive field program at its flagship Sandy Mitchell rare earths project in northern Queensland.
Pluton is 7.6km east-northeast of the Mutchilba township on the Mareeba Dimbulah road and about 26.5km southwest of Mareebah.
OzAurum Resources (ASX:OZM)
Further high-grade gold results have been received from RC drilling at the Cross Fault discovery within OzAurum Resources' Mulgabbie North project northeast of Kalgoorlie.
The project hosts a resource of 260,000oz at 0.7g/t gold, with 64% in the higher confidence measured and indicated categories.
Recently discovered Cross Fault is 1.3km south of the existing resources and enhances the overall prospectivity of Mulgabbie North.
Results from eight RC holes include:
10m at 1.80g/t gold from 127m and 1m at 3.91g/t to the end of hole within 35m at 0.79g/t from 103m;
8m at 1.81g/t from 68m within 22m at 0.84g/t from 66m;
7m at 2.17g/t from 79m;
7m at 1.25g/t from 33m within 26m at 0.75g/t from 29m; and
4m at 2.70g/t from 18m;
These have seen shares increase up to 12.4% to a daily high of 10c.
OzAurum Resources (ASX:OZM) said the drilling continued to confirm the presence of high-grade gold mineralisation over a substantial 400-metre strike length, validating the potential of this new discovery.
'The extension of this high-grade mineralisation into fresh rock, beyond the areas tested by previous aircore drilling, significantly expands the potential scale of this discovery,' CEO and MD Andrew Pumphrey said.
'The intersection of wide sulphide zones further bolsters our belief in the potential for a substantial gold system.'

Record clean energy surge set to break Australia's coal reliance
The threat of blackouts hitting Australian homes and businesses once the next wave of coal-fired power stations retire has been downgraded significantly as official forecasts now expect enough new renewables, batteries and transmission lines will be available to keep the lights on. Over the past 12 months, more wind, solar and storage capacity was added to the eastern seaboard's electricity grid than in any year before, the Australian Energy Market Operator says in an update to be released on Thursday. It also forecasts that the year's record investment in 4.4 gigawatts of generation and storage will be surpassed by even bigger increases in the years ahead. AEMO anticipates between 5.2 gigawatts and 10 gigawatts to come online annually from now to the end of the decade, aided by government schemes underwriting the financing of billions of dollars of new projects. 'The 10-year investment pipeline to manage energy reliability is healthy,' AEMO chief Daniel Westerman said. Australia is experiencing one of the world's fastest energy transitions as polluting coal-fired generators, which still supply most of the grid's electricity, reach the end of their lives, while wind and solar farms and household rooftop solar panels are expanding their role in the grid every year. Loading But officials, including AEMO, have long been worried that the build-out of large-scale renewables and storage, and the thousands of kilometres of new power lines to link them to major cities, was still lacking the speed necessary to compensate for further coal closures without heightening risk of power shortages or price spikes. Critical projects have been running into problems including permitting delays, soaring construction costs, equipment shortages and significant pushback from rural and regional communities worried about impacts on farming practices, property values and the environment. Nervous about the lagging pace of the rollout, the NSW government last year cut a deal with Origin Energy to keep the giant Eraring coal-fired power plant operating until 2027, a timeline some in the industry think may need to be pushed out further still. The Victorian government, meanwhile, has agreements to ensure two of its biggest coal generators – EnergyAustralia's Yallourn and AGL's Loy Yang A – do not shut prematurely.

Bigger properties occupied by smaller households in major housing mismatch, Cotality finds
In a reminder of how broken housing affordability and access is, new analysis highlights a major mismatch between the size of Australian homes and the number of people living in them. While the vast bulk of Australian housing is built for larger families, property research firm Cotality has found more than 60 per cent of households are made up of just one or two people. It reveals a misalignment between "who lives in our homes and the kinds of homes we're building", Cotality's head of head of Australian research Eliza Owen said in the report. "Of the lone-person households in Australia, the data suggests around 40 per cent are aged 65 and over," Ms Owen said. "The highest share of households is two people, but the highest share of housing has three bedrooms. "While there's nothing wrong with more bedrooms than people in a dwelling, there could be some inefficiencies in the way housing is being allocated," Ms Owen said. "After all, a 'traditional' family of four may have more need for a three-bedroom dwelling than a household of two people." The report cited data from the 2021 Census, which showed there were more two-person family households in three-bedroom dwellings (about 1.3 million), than three or four-person family households (about 1.1 million). Ms Owen has suggested a way to fix the "efficiency question", which she knows is not politically appealing — send a price signal. "Governments could make it more expensive to have more housing than you need, and cheaper to live in smaller housing," she wrote in her research note. She said that logic often leads to calls for tax reform including abolishing stamp duty to cheaper to move between housing, replacing it with a broad-based land tax (which raises costs the more land you own). "These options are both politically difficult as it would involve moving from a tax that applies to a small amount of voters each year who purchase property to one that will tax two thirds of voters (property owners)," she noted. Independent housing researcher Cameron Kusher, speaking to The Business in July, argued high transaction costs, namely stamp duty, discourage moving to a "better sized property" and can lead to people purchasing larger homes than they need to begin with. "People just feel like if I can get a better and bigger home sooner, that's a better outcome," he said. "If we look at what is being built, it's usually very large houses, four or five bedrooms, taking up most of the land on these new housing sites," Mr Kusher said. "A lot of it comes down to how much a piece of a property, [and] how much the land and the house, costs. "I think a lot of people are building bigger homes, thinking 'I'll spend a little bit more up-front and my family will grow into this home'. "It might just be a couple grandkids, or they're planning to have a couple of kids." He noted the effects of rapidly increasing property prices, which can leave people priced out of re-entering the market, and the fact that larger properties can be more likely to appreciate in value at a faster pace. Cotality's Ms Owen said other policy options to encourage people to move into appropriately sized homes could include reforming pension asset tests to include the value of the family home. "Strides are already being taken on the supply side to establish well-located apartments in our larger cities, that can accommodate smaller households. "But shifting demand through tax reform could help the take-up of these new homes." The government has accepted it is not on track to meet the target to build 1.2 million homes in five years, but Treasurer Jim Chalmers has stood by the ambition, despite Treasury advice it would not be met. In another recent note, Ms Owen questioned the focus of state and federal governments on speeding up building approvals to boost housing supply, warning that the construction industry simply cannot keep pace. "With completion times already above average and construction costs elevated, it seems an odd time to be incentivising more dwelling approvals and commencements," she said. Cameron Kusher argued past experience could be a guide on how to approach today's housing problems and ease the construction crunch. "Maybe we need to go back to how things were 30 or 40 years ago, where you have smaller homes and you make them easy to renovate," he told The Business. "Over time, people can actually add bedrooms, bathrooms, car parks, verandahs and all these sorts of things to add value to the home.
