OCT eyes Tasmanian copper-silver-zinc play
Historical drilling returned significant mineralisation intercepts.
Octava raises $1.5m through a two tranche share placement for exploration and metallurgical testwork
Special Report: Octava Minerals has signed a conditional agreement to acquire the Federation copper-silver-zinc project in western Tasmania and received firm commitments from sophisticated investors for a $1.5m placement.
Federation comprises two granted tenements covering 121km2 about 12km west of the town of Zeehan and is on the margin of the Heemskirk Granite dome – a multiphase intrusion containing various phases of mineralisation.
It is close to several mining centres with processing and infrastructure, as well as a number of hydropower stations.
The project has seen historical exploration with Renison drilling 18 diamond drill holes into the Sweeney's prospect in the late 1970s.
While eight of the holes missed the target mineralisation, the other 10 holes returned significant intersections such as:
23m grading 1.19% copper, 1.70% zinc, 121g/t silver and 1.17% tin from 71m;
24m at 0.25% Cu, 0.52% Zn, 42g/t Ag and 0.27% Sn from 112m; and
31.4m at 0.19% Cu, 1.92% Zn, 31g/t Ag and 0.62% Sn from 210m.
Despite these results, the shape and full tonnage potential of the Sweeney's mineralisation is not well understood with Octava Minerals (ASX:OCT) noting there are strong indications from the historical drilling that a potentially larger remobilised volcanogenic massive sulphide system might be present.
Adding interest, the wider Federation project area contains a number of additional prospective exploration targets, which will also be investigated.

Placement to fund exploration
Demonstrating its firm belief in the prospectivity of Federation, OCT has raised $1.5m through the issue of 50m shares at 3c each to fund preliminary, due diligence exploration and drilling.
The two-tranche placement will include one free attaching option exercisable at 8c and expiring in three years for every two shares applied for.
Proceeds will also be used to continue encouraging metallurgical testwork with CSIRO at its Byro REE/Li project in Western Australia's Gascoyne region.
'We are very pleased with the strong support for the placement which will be used to continue our planned exploration program and allow us to commence due diligence on the Federation project in Western Tasmania,' chief executive officer Bevan Wakelam said.
'The option on Federation provides a unique opportunity.
'Previous drilling by Renison back in the late 70's at the Sweeney's Prospect encountered significant intersections of copper, zinc and silver, that were never followed up, due a focus on exploration for tin at the time.
'The historic mineral grades, alteration assemblages and geological structures encountered at Federation point to a potentially significant discovery opportunity. The western region of Tasmania has a strong history of prospectivity and mineral discovery.'

Silver prices are soaring and these ASX juniors are along for the ride
Silver saw a considerable price bump in July and while not as high as its pal gold, the jump could be beneficial for a bunch of silver juniors on the ASX. Silver rose to nearly $39/oz, that's a 30% jump and the highest since September 2011 – with investors flocking to safe-haven assets thanks to escalating US trade tensions. US President Donald Trump has announced 30% tariffs on most imports from the European Union and Mexico, with the latter being the largest producer of silver and a key supplier to the American market. The silver surge has also been driven by industrial demand from solar energy, electronics and green technologies, with the metal primarily used in photovoltaic (PV) solar cells as a key material for the electrical contacts that allow the flow of electricity generated by the solar panel. Analysts at Citigroup flagged that prices for the precious metal could hit $43/oz in the next 6-12 months. West Coast Silver (ASX:WCE) executive chairman Bruce Garlick said there was no reason why silver couldn't hit +$40/oz in the next 6-12 months. 'With a combined industrial demand and continued gold:silver ratio of about 90 the only logical result is that prices will rise,' he said. The company holds the Elizabeth Hill project in WA and is just one of several juniors on the ASX keeping a close eye on the silver price, confident the future is bright for mining the precious metal. The project previously produced 1.2Moz of silver from just 16,000t of ore grading 2194g/t Ag in 2000 before it closed due to a low silver price of US$5 an ounce. But recent drilling by WCE has returned bonanza grades of up 21m at 1047g/t Ag from 10m and 15m at 723g/t from 1m. 'We have a high-grade silver project in one of the best jurisdictions in the world and the project is located on a mining lease which will allow rapid movement to development and production should we chose to accelerate this pathway,' Garlick said. The recent assays were only two of 12, with the company confident of even more solid hits to come. Plus, in parallel, WCE is aiming to expand exploration both near mine and beyond into the broader 180sqkm land holding. 'We want to add value with the drill bit,' Garlick said. 'We know we have high grade silver and we want to find more and then move swiftly to development and cash generation. 'We have a mining lease and nearby processing plants which will be assessed in the near term for use.' These silver juniors could be a shoo-in Before we dive into the juniors, it's worth noting there's only one silver producer right now, and that's Adriatic Metals (ASX:ADT), which declared commercial production from its Vares operation in Bosnia and Herzegovina on July 1. Broken Hill Mines (ASX:BHM) could be the next producer, having recently acquired the Rasp mine and Pinnacles project in Broken Hill where it expects more than 50% of its revenue to come from silver. Then there's Boab Metals (ASX:BML) who're acquiring Sandfire Resources' (ASX:SFR) DeGrussa plant for use at the Sorby Hills lead-silver project in Western Australia. When you consider silver is expected to reach a market deficit of around 117.6Moz in 2025, that leaves plenty of slices of the silver pie up for grabs if any juniors can get into production. Last month, Maronan Metals (ASX:MMA) released a resource update at its namesake lead-silver project in Queensland to 33.1 Mt at 6.0% lead, 108 g/t silver. That includes an indicated (higher confidence) silver-lead resource of 5.3 Mt at 5.2% lead, and 116 g/t silver. Red Metal (ASX:RDM) also has exposure here, owning 44% equity in the company. Argent Minerals (ASX:ARD) is gearing up for drilling its 63.7Mt at 69.75 g/t silver equivalent for 142.8Moz Kempfield project in NSW, The plan is to assess early production opportunities and lay the groundwork for full-scale development. The testwork will evaluate multiple processing pathways, including heap leach and carbon-in-leach (CIL)/flotation options, with the findings expected to form the basis of a scoping study. Taruga Minerals (ASX:TAR) has reported up to 103g/t silver in recent rock chip sampling at its polymetallic Thowagee project in WA. The Thowagee tenement is especially interesting, as it features two historic polymetallic mining operations, with the Thowagee mine previously producing 15.2 tonnes of lead and 5878 grams of silver. An expanded soils and rock chip sampling program is planned, aimed at uncovering more anomalous mineralisation trends adjacent to historical workings, and expanding the strike of the known workings trend. Australian Critical Minerals (ASX:ACM) recently entered into a binding share purchase agreement to acquire Circuit Resources which owns or has the option to acquire the concessions associated with the Blanca, Riqueza, Flint, Cerro Rayas, Liro and Kamika projects in Peru. These are primarily focused on gold and copper with silver, base metals and lithium. Riqueza, is most notable, being adjacent to tenements held by Anglo American, and home to historic silver grades from rock chips of up to 2238g/t. Drilling permitting is planned for the second half of 2025. Silver Mines (ASX:SVL) has taken a major step forward to aid the redetermination of the Development Application for its Bowdens project near Mudgee in NSW, while also pursuing growth opportunities across its expanding portfolio. The company has now provided all information requested by the NSW Department of Planning, Housing and Infrastructure (DPHI) to assist with the redetermination. Antipa Minerals (ASX:AZY) also has a dash of silver, 666,000oz to be exact, at its Minyari Dome project in WA. Who else has silver exposure? Firetail Resources (ASX:FTL) also has some silver up its sleeve, with results of up to 6630g/t returned from mapping and sampling at its new Excelsior Springs gold project in Nevada, USA. The company recently entered into an option to acquire 80% of the project, and while gold is the main focus, there's a secondary silver opportunity around the Blue Dick mine. Sierra Nevada Gold (ASX:SNX) reported more than 3400g/t silver in rock chip sampling at its Blackhawk project in Nevada back in March, highlighting some serious multi-element potential. Standout results included 3460g/t silver, 1.47% copper and 0.38% antimony, 256g/t silver, 4.52% copper and 0.83g/t gold, and 10g/t silver and 0.33% copper. White Cliff Minerals (ASX:WCN) also has some silver at its Rae (predominately copper) project in Canada, with drilling last quarter intersecting up to 34.1g/t silver. Then there's Lithium Universe (ASX:LU7) who are taking a different approach to the precious metal with its recently acquired solar panel recycling technology. The plan is to recover silver during the recycling process. While the tech is currently in the patent submission stage, the licence will be made available to LU7 once it is ready. At Stockhead, we tell it like it is.

Loyal Metals will use high-tech drone survey to unlock copper-gold targets at historic mine
LLM to launch high-tech survey to delineate new targets at Highway Reward mine Survey can investigate depths 3-4x deeper than when the project was historically mined Modern exploration backed by $4.4m in available funding Special Report: Loyal Metals will launch the world's highest-resolution geophysical survey, a drone-based MobileMTd survey, over its Highway Reward copper-gold mine in Queensland. The mine, which previously produced 3.65Mt at 5.7% copper and 260,000t at 4.5 g/t gold, has seen no geophysics since a feasibility study in 1997 — despite copper and gold prices increasing by 664% and 1,317% respectively. This is where Expert Geophysics' cutting-edge MobileMTd technology comes into play. The tech is capable of investigating depths beyond 1,000 metres. For context, the historical mine was only mined to depths of around 220m for the open pit, and 390m underground. The aim of the survey is to generate a high-resolution 3D model to highlight remnant mining and exploration potential at the project. Loyal Metals (ASX:LLM) said the results would be integrated with existing exploration and mining data to enable AI-powered software to model subsurface geology and define new drill targets at depth and along strike. Next phase of discovery Backed by $4.4m in available funding, LLM is well-positioned to apply modern exploration techniques and unlock the next phase of copper-gold discovery at Highway Reward. 'The presence of exceptionally high-grade historic copper lenses supports our bold decision to implement a closely spaced survey, aimed at unlocking the full potential of this unique VMS system,' LLM managing director Adam Ritchie said. "By combining MobileMTd technology with extensive historical data and AI-powered modelling, we're unlocking geological insight rarely seen in the industry. 'Our strong partnership with Expert Geophysics, gives us confidence this survey will deliver outstanding results. 'With solid funding and modern tools, Loyal is ready to reignite exploration at Highway Reward and uncover its next chapter." Along with the historical mine, the project hosts a 3km northeast-trending corridor of underexplored massive sulphide mineralisation which will also be subject to the MobileMTd survey.

AFL CEO Andrew Dillon says Tasmania must meet stadium deal before 2028 entry
AFL chief executive Andrew Dillon has doubled down on the importance of Tasmania meeting its licence agreement before entering the competition in 2028. Tasmania was alongside the other 18 clubs for an AFL summit at Marvel Stadium on Tuesday morning. The Devils, however, are facing a nervous wait after the slated cost of their roofed stadium blew out $100m more than the original estimate. Dillon said he was 'really confident' Tasmania would join the AFL as planned in 2028 but reinforced its contractual conditions of entry. 'Having someone of Brendon Gale's calibre put his hand up to lead an expansion team is super important for the industry,' he said. 'It's great to see the Tassie Devils there alongside our other 18 clubs … I am really confident the Tassie Devils will get going in 2028. 'There's complexity but there's always complexity when you're bringing in a new franchise, a new licence or a new club. 'But I am really confident we'll get there and we'll work with the Tasmanian government to make sure all the conditions of the licence are met, which includes there is a stadium with a capacity of 23,000, with a roof at Macquarie Point … as long as all those points are ticked, the licence becomes unconditional and then we start at 2028.' The AFL summit kicks off discussions between the clubs on how to grow the competition. Dillon has a vision of 10 million attendees, two million members and one million participants across both AFL and AFLW competitions. But he said the discussion of an in-season tournament would not be included and instead be presented to the competition committee. 'What we're talking about for the next couple of days is really focusing in on fan first, we're not really getting into the heavy football stuff,' he said. 'We talked a little bit about that with the CEOs and that will be something we'll take back to the competition committee. 'I think what we want to make sure is that our game is as attractive as it has been. We had records crowds last year, an average of 37,600 people came to our games. 'We're on track to exceed that this year, but we don't want to stop at that, we want to have average crowds of 40,000. 'We just want to make sure our game remains accessible, affordable and as popular as it has been.' The fixture has come under fire in recent weeks, with the injury-ravaged Essendon and flailing Carlton owning major prime-time slots. Dillon defended the floating fixture and particularly the Thursday night slots that have recently netted smaller crowds in Melbourne. 'The Thursday nights this year, I talk about season averages for crowds and Thursday nights have been above the average – that's a tick,' he said. 'Thursday nights have rated extremely well, but I think what's important is we do have a spread of teams who play through those different slots. 'We have evolved the fixture over the last couple of years, which is not as popular with all of our fans, but we think it's one important part. 'Maybe this year is a bit of an outlier in terms of the teams that were selected earlier on were teams in pretty solid form at the time the floating fixture was put in. 'The games are still rating pretty well, they're still pretty well attended, but we'll take on-board the feedback from fans, broadcasters and clubs as we look to the 2026 fixture.'
