Resources Top 5: Core's Finniss could reemerge as one of the world's most cost competitive lithium mines
Core Lithium lays out low-cost path back to production for Finniss project in NT
Highfield sells the farm (supplies) to China
Nimy starts gallium drilling at Block 3 in WA
These are your standout small cap resources stocks for Wednesday, May 14, 2025.
Core Lithium (ASX:CXO)
Core's Finniss operation was the earliest casualty of the epic collapse in lithium prices across 2023, shutting up shop in early 2024 as the small scale NT lithium mine ran into heavy lossmaking territory.
That prompted a major rethink, return to exploration and change of management.
The fruits of that labour have now been floated for the market to see, with a new study suggesting a restarted mine would be among the most cost competitive spodumene operations globally.
Finniss, then focused around the Grants open pit, was running at a unit cost of $1953/t in its last quarter of full operations (December 2023).
The new study, focused on a 20-year underground mine at the BP33 deposit, would run at just $690-785/t FOB on an SC6 (6% Li2O concentrate) basis, with mining costs down 40% and processing costs 33% lower.
Concentrate production would also rise 7% to 205,000tpa SC6, with recoveries of 78% and pre-production capex chopped 29% from $282m to $175-200m.
Morgan Stanley has been appointed as Core's corporate advisor to lead its funding strategy "with a focus on minimising dilution for shareholders", suggesting debt funding will be a key pillar of the junior's strategy.
Any FID, of course, depends on market conditions and funding. Spodumene is currently priced around multi-year lows of US$700/t, according to Fastmarkets. Core's study assumes a long-term lithium price of US$1300/t to come to its free cash flow number of $1.2bn.
Nevertheless, Core CEO Paul Brown said the restart plan focused on Finniss' strengths after a 'rigorous, bottom-up review of every aspect of the operation.'
"The Study brings together our operating experience to deliver a plan that is more robust, more efficient and built for the long term," he said.
"At BP33, we are developing a large-scale underground mine. Grants will shift to underground mining, cutting costs and doubling its mine life. Carlton will use Grants' surface infrastructure, supporting a 20 year mine life.
"Blackbeard offers further potential to extend mine life and expand operations. Our plant upgrades will improve recovery and reduce contaminants, whilst keeping capital costs low.
"These improvements include enhanced screening, with more affordable crushing and the addition of a gravity circuit. This resets Finniss as a more resilient operation to price volatility, and will be a reliable source of high-quality, coarse-grained spodumene concentrate.
"The Study outlines a lower-cost, longer-life, and scalable operating plan that generates free cash flow of $1.2 billion, representing a six-fold return on pre-production capital."
Core shares have tumbled 94% from their 2022 highs of $1.67, but hit a near four month high of 9.6c after the release of the restart study.
A major catalyst to upscale the project could come from Blackbeard, which has an exploration target of 7-10Mt at 1.5-1.7% Li2O, well above the reserve of 10.73Mt at 1.29% Li2O in terms of grade.
Argonaut's Hayden Bairstow has a 17c price target and spec buy rating on Core, saying the study came in stronger than expected.
"Unit costs were 25% lower than we had expected, and an impressive 40% lower than the previous study," he told clients in a note.
"The exploration target for Blackbeard highlights the potential to add a second material ore source, which could push the mine life beyond 20 years, sustaining production at the ~205ktpa (SC6) capacity rate, or underpin an expansion beyond the base case."
Highfield Resources (ASX:HFR)
While the idea of competing with China has become a PR gold mine for critical minerals stocks, Chinese capital is still a major bonus for a small cap if you can get it.
And Owen Hegarty-backed Highfield Resources is certainly in that camp, surging on Wednesday after coming out of a trading halt to reveal a raising that will pump US$300 million of fresh equity capital into the $70m capped firm from Qinghai Salt Lake.
Qinghai is a subsidiary of Chinese industrial giant China Minmetals, and has signed a non-binding letter of intent to deliver the raising conditional on the completion of Highfield's acquisition of the Southey potash project in Saskatchewan, Canada, from Yankuang Energy, the main shareholder of Aussie coal producer Yancoal.
Qinghai would wind up with controlling power over Highfield if the deal goes through. The firm, which owns the Muga potash project in Spain, has long been backed by Owen Hegarty's EMR Capital and connected shareholders.
Shenzhen-listed QSL currently produces some 5Mt of potash fertiliser and 40,000t of lithium carbonate, and is the largest producer of the agricultural product in China.
The deal follows the resignation just last week of Highfield's CEO and MD Ignacio Salazar. Meanwhile, EMR will provide €1.15 million in a standby loan facility to keep the lights on as it moves to complete the deals with Yankuang and now Qinghai.
'The support from EMR reflects its commitment to Highfield and the strategic value of the Muga Project. The Company is undergoing a natural evolution as it moves closer to securing the right partnership structure for development," HFR chair Paul Harris said.
Qinghai will have exclusive rights to conduct due diligence until June 30.
Now to some real microcap stuff, as $2m Carbine Resources, priced cheaper than a Cottesloe condo, runs 50% on the news that it has a mining lease for its Muchea West Silica Sand project.
It's not total, the newly granted mining lease covers "a portion" of the 110Mt at 99.65% SiO2 resource at Muchea West.
The balance is on a granted exploration licence called E70/4905.
There's a further catch. Having a mining lease doesn't mean Carbine can go in and mine the high grade silica sands (used for glassmaking and more) from the site, located next to the Pinjar Rifle Range.
Mining remains subject to a host of statutory approvals and consents, including environmental approvals and consents relating to the Muchea Air Weapons Range.
"The Company has been working closely with key project stakeholders, including DEMIRS and the Department of Defence, for a considerable period to progress towards securing a mining lease and will look to build on these relationships through the next approvals phase," the company said in a statement on Wednesday.
"Further updates will be provided to shareholders in due course. In order to allow the grant of M70/1433, the Company withdrew its previous mining lease application M70/1422 and exploration licence application E70/6625 which encroached on M70/1433."
CRB also owns the Down South silica sand project over 58km2 of exploration licences 10km southeast of Bunbury, where it recently secured access agreements with three landowners, paving the way for on-ground exploration to begin.
Nimy Resources (ASX:NIM)
Nimy shares are on a run, climbing close to 15% for the second straight day after announcing the start of a second round of drilling at the Block 3 project, part of its broader Mons project ~370km northeast of Perth.
Block 3 is a potentially unique Western source of gallium. Typically produced as a by-product of alumina and zinc refining, Block 3's high grades and mineralogical characteristics mean it could shape up as a rare primary source of the metal, known for its performance-enhancing properties in semi-conductor chips, solar panels, EV and wind turbine motor magnets, LCDs and more.
The metal's supply chain is also ~98% controlled by China, placing strategic importance on discoveries outside of the Middle Kingdom.
Nimy already has a partnership with M2i Global, a group which could facilitate potential sales to the US Department of Defense should the project prove economic.
The next key step is to deliver a maiden resource estimate, a potential outcome from the current and next round of drilling. Block 3 boasts an exploration target of 9.6-14.3Mt at 39-78ppm gallium.
But mineralogical assessments by the CSIRO have shown the chloritic schist rocks believed to host the highest concentration of the metal could run 400-800ppm gallium.
'The commencement of this round of drilling at the Block 3 Gallium discovery is significant as we move forward in defining a world class JORC compliant high grade gallium deposit,' Nimy managing director Luke Hampson said.
'Concurrently, Curtin University are working on metallurgical testing following CSIRO identification of high grade 400-800 g/t gallium in chlorite.
'These exploration milestones move Nimy closer to meeting the need of gallium customers who have made initial enquiries as to our progress.'
Drilling is expected to take three weeks, with results due thereafter. NIM shares have lifted 50% YTD.
(Up on no news)
Asimwe Kabunga's RMI is another very small cap, though it's slightly larger today after an 80%+ run in its shares.
No news to speak of on market, but RMI did have some exploration updates from its Stalike and Kabungu prospects at the Mpanda copper, gold and nickel project in Tanzania to digest on Tuesday morn.
Previously announced results have included rock samples of up to 36.7g/t Au and 11.89% Cu from Kabungu and 13.58% Cu and 3.24g/t Au from Stalike.
RC drilling has also hit narrow gold intercepts in shallow locations at Kabungu.
Located close to the operation Katavi processing plant, RMI says ongoing sample analysis of auger drilling and soil samples will be combined with previous exploration results from Kabungu and Stalike to generate drilling targets.
'Ongoing exploration activities at our highly prospective Mpanda Copper-Gold Project have produced some spectacular high grade results and they are helping the Company define opportunities for exploitation of potential economic resources within our extensive tenement package," exec chair Asimwe Kabunga said on Tuesday.
"Our goal is to identify one or more significant Copper-Gold projects at Mpanda, and we have every confidence that we can achieve this. A targeted drilling programme is planned for the Stalike and Kabungu prospects following completion of this current soil and auger sample analysis work stream.
"Mpanda is clearly a richly endowed mineralised system. The extensive number of small scale operations demonstrate that systematic, modern exploration has the potential to define larger scale Copper-Gold systems.'

ACT opposition leader's first budget reply speech upstaged by Greens' health levy opposition
Despite her long career in show business, Leanne Castley may never have been upstaged quite like she was in the ACT Legislative Assembly on Thursday. But the last week may have provided material for some new country songs. The Canberra Liberals leader rose to her feet for her first budget reply speech; a major set piece event for someone who admits she's not a "typical politician". At the conclusion, she left the chamber with an easy smile, embraced by supporters congratulating her on a job well done. Yet it was the speech that followed — from ACT Greens Leader Shane Rattenbury — that left the biggest mark on budget week. The Greens' decision to oppose the government's $250 health levy is a sign that, when it comes to passing bills in this assembly, the Animal Farm theory applies; some MLAs are more equal than others. The Liberals can but oppose, while the Greens — flexing their crossbench muscle — are the ones the government must pay attention to. This is arguably the most significant political fight the minor party has picked with its former coalition partner so far. The question now is how the fight ends. Negotiations began yesterday, with no clear resolution. The Greens have indicated they're open to means-testing the levy, if it can't be removed from the budget entirely. But if either side makes the political calculation they should play hard ball, its fate could hang in the balance for months, with the assembly not sitting again until September. Greater costs for ratepayers may have been foreshadowed when Treasurer Chris Steel said there would be "tough decisions" at his mid-year budget update. The levy, however, shocked many — and stands in stark contrast to the pre-election budget we got last year which contained few, if any, surprises. It's not unusual for governments to get the tough budget out of the way in the first year of a term. But this is also not Labor's first term. By bringing down a budget of this nature after 24 years in office, the government is setting a high bar for itself to have made significant improvements by the time voters next go to the polls. Part of why Labor was successful last year even after six terms was the ability to stake a claim as the superior economic managers. The chief minister famously accused the opposition of "magic pudding economics" during the leaders debate. He might have been wishing for his own magic pudding this week. The events of the last few days have taken some of the attention away from an opposition leader, who could have used an unobstructed moment in the spotlight. Ever since Peter Cain's departure from shadow cabinet last week, Leanne Castley has struggled for clear air, with an ongoing dispute about exactly how his resignation came about. Her budget reply was the ideal opportunity, but through no fault of her own, it failed to provide the kind of moment she was after. Attention now turns to the forthcoming announcement of the revised shadow cabinet, which may provide another reset moment. If there is any lesson from a budget week, it is surely that nobody gets everything they want.

'Outsider' farmer find success raising free-range ducks for top restaurants
In a picturesque valley on the Southern Tablelands of New South Wales, maremma guardian dogs keep watch as thousands of white ducks waddle over grass and splash around in dams. Destined for the food service industry, including some of the country's finest restaurants, these free-range ducks have helped Luke Winder earn a reputation as a serious farmer. The former electrician from Sydney's south started thinking about farming while caring for his terminally ill father more than a decade ago. "He asked me some questions on his way out that made me really think about what I was deeply passionate about," Mr Winder said. With no family connections in farming, he turned to an unlikely source of inspiration. Mr Winder's regenerative farming idols include Americans Will Harris and Joel Salatin. "I think they're forging the path for future generations of farmers and how we really should be treating animals and the way we should be growing food," he said. Mr Winder and his wife Pia bought the 48-hectare farm they now call Tathra Place 10 years ago. The couple bought goats to clear the weeds, but when that failed, they turned to pigs, who happily ate the plants, roots and all. "We went from about 65 acres of blackberry, believe it or not, and we let the pigs do what they do naturally and without any chemical or mechanical means we were able to eradicate [it] all." Mr Winder is upfront about the circumstances that led to a change in career and lifestyle. He bought and sold a Sydney property and bought the farm with the profits. He also didn't pay himself a wage for nearly five years. "And that's only because I've got an incredible wife that just had a wonderful career and could support that financially and emotionally." Mr Winder now leases nearby land as well, but this small-scale operation produces between 7.5 to 9 tonnes of protein each week. As well as pork and duck, it includes beef, lamb and chicken. Mr Winder said they must hit these figures to make his model work, not an easy task for a "chemical-free, pharmaceutical-free" regenerative operation. The business is also a vertically integrated model, where they control nearly every stage of production, which Mr Winder says is also necessary to be profitable. "We have our own butcher shops, we're doing our own wholesale production. We're breaking down birds and doing all the packaging." Mr Winder and his staff also handle all live animal transport and cold-chain logistics after processing, including deliveries to Sydney and Canberra restaurants. Direct sales to the food service industry are integral to the business model, especially for duck, an often difficult sell to home cooks. Tathra Place is now one of the biggest free-range duck producers in the country and markets the fine dining birds as Maremma Duck, a nod to the 23 dogs who protect them day and night. Mr Winder enjoys the support of well-known chefs who are enthusiastic about his ducks and his free-range farming methods. Bennelong at the Sydney Opera House has served his ducks for almost as long as he has produced them. "The flavour profile immediately jumped out and surpassed any other duck that we tried," head chef Rob Cockerill said. Mr Cockerill believes their free-range environment enhances the flavours and said diners were interested in the back story of menu items like duck. While Mr Winder would like to steadily expand the operation, the increasing price of agricultural land is a major hurdle that he and other young farmers face. "Unfortunately where I am here, it's being essentially captured by hobby farmers and people that want their 100 acres or 200-acre blocks where it's only two hours from their house in Sydney," Mr Winder said. He believes changes should be made to ensure land zoned by governments for primary production is used for that purpose. Mr Winder is optimistic about the future of agriculture and plans to put together a training model of his practices for others to follow. He said there was a simple goal. "To be ecologically responsible, but still be able to earn a white-collar salary. "We're never going to attract young people into agriculture if there's not a fair living to be had."

Geelong laneway breakthrough wins Victorian Architecture Award
An innovative Geelong laneway breakthrough project inspired by Melbourne's iconic alleys has won a Victorian Architecture Award. The Malop Arcade 'surgically repurposed' an existing inner city building to create a new pedestrian link between hip dining strip Little Malop St and Malop St. It's the first in a series of urban laneway projects planned to boost pedestrian connectivity across the Geelong CBD. Why Geelong's home target isn't stacking up The public arcade garden, designed by NMBW Architecture Studio with ASPECT Studio, was recognised in the Small Project Architecture category at the 2025 Victorian Architecture Awards. Two other extraordinary beach houses on the Surf Coast also won awards in Residential Architecture New Houses category. Kerstin Thompson Architects' Otway Beach House is a monolithic concrete residence build in a designated 'flame zone' on the edge of a national park. Multiplicity designed the other whimsical Aireys Inlet recipient, She Sells Sea Shells, which features shell-encrusted cabinetry, vintage 1970s upholstery and cork floors. The Malop Arcade project, developed by a state government department and the City of Greater Geelong, saw a two-storey shop in Malop St spot purchased and its interior selectively demolished to create an urban garden and public pathway connected to Dennys Place. Rainwater is channelled into planters and new sunken garden beds set among exposed bluestone walls and timber rafters. 'Through adaptive reuse and alteration of a two-storey building, NMBW has created a generous, poetic pedestrian link and public space that stitches together the laneways of Geelong's CBD,' the judges' citation said. 'Through detailed forensic investigation by the project team, this exemplary project has carefully and meticulously revealed the site's unique layers of history. 'With a nod to the memory of the original building, new elements – noticeably a galvanised steel earthquake structure – stand in deliberate contrast to the existing brick, timber and bluestone fabric.' Visitors have reported homeless people seeking refuge in the laneway since it opened. The client quoted in the project summary sees this as a positive aspect of the space. 'I think the highlight of the space was the area where men who were sleeping rough would be sitting talking to each other in a warmly lit area surrounded by nature,' the client said. 'This space never felt unsafe as a pedestrian. I am a mental health clinician and it always struck me that this space fostered safety, not fear, which is unusual for many public spaces in cities now.' Construction has now started on Geelong's second laneway breakthrough after the demolition of two Ryrie St buildings. They were knocked down to create an open air link between Union and Markets streets, due for completion by mid 2026.
