Broken Hill Mines (ASX:BHM)
After 120 years of mining silver, lead and zinc, and being the birthplace of mining giant BHP, Broken Hill is again directly represented on the stock exchange after producer and explorer Broken Hill Mines made its debut.
And it turned heads, opening at 47.5c and reaching 51.5c in early trade, a 454% increase on the previous close of predecessor Coolabah Metals with more than 8m shares exchanged.
BHM has quickly got to work, with the drill spinning in a bid to increase silver, lead and zinc resources at the Pinnacles mine west of the mining stronghold of Broken Hill and its existing Rasp underground mine.
A 4000m program is aimed at growing the size and grade of its current 6Mt resource at the Pinnacles, which runs at an impressive 10.9% ZnEq. As well as 4.7% zinc, the resource includes 153g/t silver, 3.3% lead and 0.5g/t gold.
BHM also has another 3000m of earlier drill core from Pinnacles in the queue for assays, with first results expected in the next month or so.
This new drilling follows results released earlier this year including 8.9m at 927g/t Ag, 12.2% Pb and 1.3% Zn from 11 metres.
Broken Hill Mines (ASX:BHM) listed on the ASX after a reverse takeover of Coolabah Metals, which consolidated two of three mining companies that control the silver, lead and zinc operations at Broken Hill. The reverse float included the injection of $20m in fresh capital from investors.
While Pinnacles is set to play a role in future growth, the Rasp underground mine with access and surface facilities on the town's Line of Lode is the flagship.
The mine produces around 25,000tpa of zinc equivalent metal, but there are plenty of opportunities to improve the outlook.
Despite the Rasp plant's 750,000tpa capacity, the project has been campaign milled since 2020 and ore feed grades are around 6% ZnEq.
'We bought an operating mine, a going concern, we've got 120 staff on day one and a hungry plant,' executive chairman Patrick Walta told Stockhead recently.
'The whole philosophy is about utilisation of sunk capital. We have this beautiful plant that's really had 500 million bucks spent on it over the years and it's only about 12 years old.
' It is only fed by one orebody and it's a relatively low-grade ore body by Broken Hill standards.'
That source – Western Mineralisation – runs at around 8.2% ZnEq, including 4.8% zinc, 3.1% lead and 38g/t silver. Yet the Main Lode grades 17.7% ZnEq, including 870,000t of ore at 7.8% zinc, 7.6% lead and 151.7g/t silver.
Walta said the mine made $20 million in operating cashflow last year with a plant running at around 40% of total capacity. When the Main Lode is online it will introduce not just more ore but ore running at 2.5x the grade.
Peregrine Gold (ASX:PGD)
While chasing gold in the Pilbara region of WA, Peregrine Gold has made what could be a very significant Channel Iron Deposit discovery just 2km from BHP's Western Ridge asset, close to the town of Newman.
This has seen securities increase 70.28% to a 12-month high of 31.5c.
Stream sediment sampling followed by further sampling and mapping by Peregrine geologists has resulted in the CID being mapped over a total strike length of 6.4km and widths of up to 200m with a further 1.3km of strike interpreted in magnetics.
Peregrine Gold (ASX:PGD) believes the discovery was missed by previous exploration programs and GSWA mapping due to its low topographical position.
Historical CID work focused on the mesas in the area to the northeast but PGD said the recent discovery represented a better preserved and far larger scale CID system than historical mesa-style CIDs and could represent a 'Valley Type' system.
Geochemical data of the CID samples has shown the material is of a consistently high grade – peaking above 61% Fe – with all CID samples taken averaging ~57% Fe.
Levels of deleterious elements are also low and considered within the parameters for high quality iron ore deposits.
It is anticipated that subject to drill testing, the depth of the CID channel may be substantially thicker in the central parts of the channel which are up to 200m wide.
Recent corporate movements have drawn attention to CZR Resources' (ASX:CZR) sale of its 85% holding in the Robe River Mesa Channel Iron Deposit for ~$75m.
Positioned next to Rio Tinto's Robe Valley operations and near major infrastructure, Peregrine believes Robe Mesa provides a useful point of reference.
Early indications suggest Peregrine's CID discovery has a scale that compares favourably to Robe Mesa.
'Our objective moving forward will be to advance the Coopers CID prospect as quickly as possible,' PGD technical director George Merhi said.
ActivEX (ASX:AIV)
A maiden JORC-compliant inferred resource of 8.5Mt at 1.13g/t gold for 310,000oz at Mt Hogan deposit resulted in ActivEX (ASX:AIV) soaring to a two-year high of 3.2c, a staggering 358% increase on the pre-trading halt close.
The historic Mt Hogan mine forms part of the Gilberton gold joint venture with Gilberton Gold Pty Ltd. The project is in northeast Queensland, about 300km from Townsville.
'The journey towards our maiden gold resource commenced in 2022 when the company made the decision to focus exploration efforts in the vicinity of the Mt Hogan gold mine,' AIV MD Mark Derriman said.
'Three phases of RC/core drilling culminated with the most recent RC drilling program in November 2023.
'Incoming JV partner Gilberton Gold Pty Ltd have been crucial to funding the project and will take over management of operations going forward with the next round of drilling planned to commence late in Q3 2025 and will comprise both RC and core drilling.'
Caprice Resources (ASX:CRS)
An 11m intersection grading 17.3g/t gold from 170m at Vadrian's deposit of the Island gold project in WA's Murchison region has seen Caprice Resources (ASX:CRS) lift 37.5% to 6.6c with more than 45m shares changing hands.
As well as this being the company's best intercept to date at Vadrian's, the first batch of assays from phase 3 drilling confirmed the recent discovery of the Evening Star high-grade lode.
Other results include 10m at 11.7g/t Au from 175m and 9m at 8.3g/t from 94m.
These have doubled the strike of the high-grade system to at least 350m and extended mineralisation at depth where it remains open in multiple directions.
Drilling to follow-up the strike extent and grade potential of historical anomalous gold mineralisation about 80m west of the main New Orient lode has also returned notable intersections such as 21m at 1.3g/t gold from 29m.
Tivan (ASX:TVN)
A second collaboration between Tivan (ASX:TVN) and Sumitomo Corporation covering TVN's Australian fluorite projects has seen shares increase 31% to 11c.
The leading Japanese trading house and Fortune Global 500 company has signed agreements for the Sandover Fluorite Project in the NT and Speewah Fluorite Project in WA.
An MoU for Sandover, a high-grade fluorite project acquired by Tivan in November 2024, will see the companies discuss the collaborative development, financing and operation of the project to be formalised through negotiating commercial agreements following delivery of a pre-feasibility study.
Tivan is working to define a deposit supportive of fluorite mining and processing at Sandover, focused on an expedited pathway to produce metspar and a traditional acid-grade fluorspar production pathway.
At Speewah the parties have established an incorporated joint venture, including Japan Fluorite Corporation (JFC), a special purpose subsidiary incorporated by Sumitomo, making an initial $5.3m equity investment for a 7.5% interest.
In parallel, Sumitomo has agreed to the Japan Organization for Metals and Energy Security (JOGMEC) becoming a partner in Speewah through acquiring a 49% equity interest in JFC.

AI SCAMS First up, AI scams. Experts say they're on the rise, and one CEO is particularly worried. This is Open AI's CEO, you know the company behind ChatGPT, and today, he shared his fears about the future of AI scams. Look, scams aren't a new problem. Just last year, Australians lost more than two billion dollars to them. And new data shows the Australian Financial Complaints Authority has received more than 100,000 complaints for a second year running. But thanks to AI, scams are only getting more sophisticated and believable. Experts say the best way to beat AI scams is critical thinking. Asking yourself: does this actually seem like the person I think it is? Does the scenario seem realistic? Families are also being encouraged to create a safeword, a word you can ask someone to say when you're unsure about their identity. UNESCO US President Donald Trump has decided to pull the US out of UNESCO, the UN's culture and education agency. According to the White House, UNESCO's values are at odds with President Trump's America First Policy. It's not the first time he's done it. Mr Trump originally pulled the US out of UNESCO back in 2017 during his first term as president. But a couple of years ago, that decision was reversed by Joe Biden, who was the president at the time. UNESCO's director general says while she's upset by the decision, she was kind of expecting it. HECS DEBT Now that parliament's returned everyone is talking about Labor's election promise to reduce student loans. Yep, today legislation has been introduced to parliament to reduce student debt. It was one of Labor's big promises ahead of this years election proposing a one-off, 20% reduction to all outstanding loans. Now, if it passes about 3 million Aussies who have debts from studying at university, or debts from doing things like apprenticeships will have their debt reduced! You see, here in Australia, it costs money to go to university but Aussie students can apply for HELP, which lets you borrow money from the government and pay off your debt bit by bit once you start earning a certain amount of money. But over the years, the cost of uni has gone up, making student debts more and more expensive so there have been a lot of calls for a reduction of student debt like this one. Meanwhile others aren't too happy with the idea because it'll cost the budget 16 billion dollars. Money that they reckon should be spent elsewhere. NIGERIA ROBOTS First up, to a robotics competition in Nigeria. Where young inventors are showing off robots they've designed to solve specific problems. Among the inventions was a land mine detecting robot, a tractor slash irrigator for farmers, and a prototype fire truck dubbed the "firebot". SHIPWRECK Now to a partial shipwreck on a remote beach in Scotland. A local schoolboy discovered it last year, and it's taken researchers until now to work out – it's actually a 250 year old wreck from an old navy boat turned whaling boat called the Earl of Chatham. BUTTER SCULPTURES And finally to these sculptures made entirely out of butter at the Ohio State fair in the US. The butter cow is a bit of a tradition here with the butter being donated by dairy farmers, and according to organisers it'll all be recycled once the fair is over.

PM will honour a big election promise as he moves to tackle cost of living
Anthony Albanese will move to freeze beer taxes on Thursday honouring his election pitch to tackle the cost of living. The Prime Minister confirmed during the election that 'we will freeze the indexation on draught beer excise for two years' in what he described as a win for beer drinkers and hospitality businesses. With schooners and pints tracking closer to $15 and $20 in major cities, publicans have expressed fears the steep prices are driving customers away. It follows warnings that a half of the cost of a $59.99 slab of Coopers Pale Ale was going to the taxman. On Thursday, the Albanese Labor Government will table tariff proposals to stop the excise and customs duty on beer from increasing from 1 August. The Albanese government has confirmed it will amend the legislation to temporarily pause the indexation on excise and customs duty. The pause on indexation for excise and customs duty will be in place for two years from 1 August 2025. The Albanese Government said that the excise and customs tariff proposals tabled in Parliament will be ratified by primary legislation to be introduced in coming months. However, the tariff proposal on Thursday will stop the price of beer increasing due to indexation until that freeze is legislated. 'Continuing to deliver cost of living relief to Australians is our number one priority,'' Mr Albanese told 'Freezing the excise on draught beer is a common sense measure that is good for beer drinkers, good for brewers and good for pubs.' Treasurer Jim Chalmers said the government remained focused on easing the cost of living for Australians. 'This will help take a bit of pressure off beer drinkers, brewers and bars,'' he said. 'Whether it's a tax cut for every taxpayer, help with energy bills, or the new relief that's rolling out this month like higher wages for award workers, we're doing everything we responsibly can to help with the cost of living.' understands the cost to the budget in tax revenue foregone will be $95 million over four years. But it's not all beer. It needs to be coming off tap in a licensed hospitality venue, so only schooners and pints of beer from your local watering hole will be blessed with a tax freeze. Those who prefer buying their beer, or any other alcohol, from the bottle-O can expect prices to keep rising. Last year Anthony Albanese said cutting beer taxes wasn't a priority for his government. 'We are not looking at that at the moment, but obviously in the lead-up to budgets, you have submissions and I'm sure that there'll be submissions along a whole range of ways,' he told 3AW. 'One of the things that we have to do though, is look at ways where we provide cost of living support, while putting downward pressure on inflation.' Health Minister Mark Butler was singing the same tune back then, insisting that the government's focus was on 'cheaper medicines, not beer'. Nationals leader's lonely call for action David Littleproud faced a backlash last year from senior Liberals after floating the prospect of a beer tax relief because the price was 'hitting a tipping point.' 'I'm part of the shadow expenditure review committee and our final taxation policy has not been determined,' he said. 'That will be determined by the National Party and the Liberal Party. That's why we'll be running the ruler over this. 'When we determine the taxation policy we'll take to the next election, it'll be a Coalition policy.' But the big idea was slammed down by the opposition treasury spokesman Angus Taylor. 'The starting point to reducing the pressure of indexation is to get inflation down,' Mr Taylor said. Opposition finance spokeswoman Jane Hume also wasn't a big fan. 'I always like the idea of free beer. But, unfortunately, that might not be the policy slogan that you'll be seeing us going into the election with,' she said. Ahead of the announcement, the Australian Hotels Association CEO Stephen Ferguson noted that beer and spirits tax quietly goes up twice a year every year and complained that the Government's only response is to refer pubs to the Australian Competition and Consumer Commission. 'Australia's beer tax is already the third highest in the OECD. There's also $38 tax on a $60 bottle of whisky or gin. That is outrageous and the voters are awake to it,'' Mr Ferguson said.

Labor to introduce new Bill to protect penalty, overtime rates for 2.6 million award workers
Labor will move to protect penalty and overtime rates for about 2.6 million workers, saying 'hardworking' Aussies rely on the entitlements to 'keep their heads above water'. Employment and Workplace Relations Minister Amanda Rishworth will introduce the Bill on Thursday, and urged the Greens and Coalition to support the proposed legislation. The law would prohibit the Fair Work Commission to reduce an overtime or penalty rate, or substitute the entitlements if it reduces the overall take-home pay a worker would otherwise receive. An award would not be able to be altered if there was evidence that even a single worker would be worse off under an arrangement which traded an overtime or penalty entitlement. Ms Rishworth said the change would protect about 2.6 million award-reliant workers. 'If you rely on the modern award safety net and work weekends, public holidays, early mornings or late nights, you deserve to have your wages protected,' she said. 'Millions of hardworking Australians rely on penalty rates and overtime rates to keep their heads above water, which is why this Bill is so critical and should receive the support of both the Opposition and the Greens.' The election promise was prompted by a FWC review launched the Australian Retailers Association to allow senior management to take a 25 per cent wage increase above minimum award entitlements in exchange for overtime, weekend and public holiday penalty rates and rest breaks. The move has been backed by the supermarket giants, plus beauty giant Mecca, as well as Kmart, Costco and 7-Eleven. Prior to the election, then employment minister Murray Watt wrote to the FWC to stop large retailers from cutting the entitlements, in a rare act of government intervention. Enshrining penalty rates was a key demand from the Australian Council of Trade Unions, with secretary Sally McManus previously arguing workers should be compensated for sacrificing their weekends. However, the legislation will likely will likely be opposed by the Coalition, with industrial relations and employment spokesman Tim Wilson stating the independent FWC was already responsible for ensuring 'workers get the best arrangements possible for a fair days work'. Instead he lashed Labor's proposed Bill as being politically motivated. 'There is no threat to penalty rates,' he said on Saturday. 'What there is, is a political focus of the Government that isn't focused towards improving the economic conditions to help small businesses grow, to enable them to go on and employ the next generation of workers, to give those first generation, those first jobs to young Australians so that they can be independent and be able to get on with their economic futures.'
