Highlights

  • Chinese refined silver output eased in October as holiday closures and smelter maintenance curbed supply.
  • Broken Hill Mines (ASX:BHM) has reported rising silver output from its Rasp and Pinnacles operations in New South Wales.
  • Iltani Resources (ASX:ILT) is working towards an updated resource and scoping study at its Orient project in Queensland.

A softer month for refined silver Supply in China has sharpened focus on where future metal will come from, and that question is drawing attention across ASX-listed Metal and Mining Stocks with silver exposure. Industry data from Shanghai Metals Market showed October output slipping as recycling paused over the National Day holiday and several copper smelters went offline for maintenance. Against that backdrop, Broken Hill Mines Limited (ASX:BHM) and Iltani Resources Limited (ASX:ILT) offer contrasting angles on the Australian silver story, with the former lifting production at established mines and the latter advancing a large exploration-stage deposit towards early-stage studies. Overseas developers, including Peru-focused Tinka Resources, are also revisiting silver-led development pathways as the metal attracts renewed interest.

Why October silver supply softened

According to Shanghai Metals Market, the monthly decline in Chinese refined silver output reflected temporary rather than structural factors. Recycled silver production largely halted during the National Day holiday, while maintenance shutdowns in some copper smelting regions left certain plants without by-product silver. Lead and zinc smelters, another important source of by-product silver, have been gradually recovering since September.

The same data pointed to softer Demand from the photovoltaic sector, where silver nitrate output fell as pre-holiday stockpiling pulled forward consumption. Shanghai Metals Market expects some copper smelters to remain under maintenance through November and December, suggesting supply could fluctuate over the remainder of the year. More broadly, the Silver Institute has flagged that the global market is heading for another annual Deficit this year, extending a run of years in which demand has exceeded supply.

Broken Hill Mines (ASX:BHM) lifts output at Rasp and Pinnacles

Broken Hill Mines operates the Rasp mine and processing plant and the Pinnacles mine near Broken Hill in New South Wales. In its June quarter update, the company described record quarterly production, supported by higher-grade ore from the Main Lode ore body and the restart of Pinnacles, where ore feed from the Edwards open pit began late in the quarter.

Subsequent reporting on the September quarter indicated that silver output and ore throughput rose again, with silver production passing a notable milestone for the company. Broken Hill Mines has also approved a tailings dewatering Facility intended to remove processing inefficiencies and support a ramp-up towards the nameplate capacity of the Rasp plant.

Looking ahead, the company has outlined plans to progressively increase feed from the Edwards pit, expand open pit mining into adjacent areas at Pinnacles and assess high-grade underground potential. An updated Pinnacles mineral resource estimate is planned for later this year.

Iltani Resources (ASX:ILT) advances Orient towards studies

Iltani Resources is exploring the Orient Silver-Indium Project in the Herberton district of North Queensland. The project already hosts a mineral resource comprising both Indicated and Inferred categories, and the company has been running an extensive infill and extension drilling programme across Orient East, Orient West and nearby veins.

Recent assay releases reported thick zones of silver-bearing massive sulphide mineralisation at Orient East, with Managing Director Donald Garner describing the results as outstanding. Iltani has said it expects to deliver an updated mineral resource estimate this quarter, which is intended to feed into a scoping study scheduled for next year. As with any exploration-stage project, reported drill intercepts are not equivalent to a resource or reserve, and further work is required to establish economic viability.

Developers abroad revisit silver-led strategies

Outside Australia, Tinka Resources has commenced an updated preliminary economic assessment for its Ayawilca zinc-silver-tin project in central Peru. The study is testing a staged concept in which open pit silver mining at the Colquipucro deposit would come ahead of underground zinc, silver and lead mining at Ayawilca, with the potential to share infrastructure and lower initial Capital needs.

President and Chief Executive Graham Carman said a staged development concept has the potential to enhance project value, with results expected early next year. The approach illustrates how developers are reassessing silver-rich deposits that previously sat behind base metal priorities.

Final Word: supply questions keep developers in view

October's dip in Chinese refined silver output appears tied to holiday closures and smelter maintenance, yet it has added to wider discussion about the depth of future silver supply. For the Australian market, Broken Hill Mines and Iltani Resources sit at different points of the development curve, with the former reporting higher production from operating mines and the latter progressing resource and study work. Both remain exposed to operational, geological and Commodity price risks, and their progress will be measured against the milestones each company has outlined.
