Deeper work has already shown the system’s legs. Drilling beneath the Main Zone intersected gold‑bearing arsenopyrite veining more than 200 metres below previous holes, including reported intersections such as 11m at 2.01g/t and 13m at 3.14g/t that confirm continuity well below the current resource envelope.
The company’s 3D modelling points to additional northeast‑plunging shoots which, if proven, could be accessed efficiently from a central underground development envisioned in scoping work. That’s the sort of geometry that tends to get the market leaning in.
Momentum is also building across Siren’s antimony‑gold flank. At Langdons, southwest of its formerly owned Reefton gold project, field mapping has rediscovered an approximate 2m shear hosting arsenopyrite and stibnite. Preliminary XRF readings at Langdons returned antimony values up to 8.5 per cent from mullock and exposed reef material, while sampling of mullock heaps delivered gold assays up to 506g/t alongside antimony to 9.3 per cent.
Conventional soils outline an anomalous gold‑antimony halo for about 400m along the fold hinge and ionic‑leach geochemistry extends the anomaly a further 200m under shallow cover – offering coherent, walk‑up targets that are now moving up the drill queue.
Further east, Siren was granted the Queen Charlotte exploration permit covering the historic Endeavour antimony mine in Marlborough, which is New Zealand’s biggest past producer of the metal. Historical records show it sent more than 3000 tonnes of direct‑shipping stibnite to England in the late 1800s, and prior test work reported recoveries of about 90 per cent from high‑grade concentrates.
Queen Charlotte’s mineralised corridor runs for at least 1.2 kilometres along strike with more than 400m of vertical extent, and its structural style evokes similarities to Auld Creek in the Reefton field, hinting at untested depth potential beneath the old workings. Auld Creek is a no‑nonsense historic producer with room to grow.
Siren’s macro tailwind is also hard to ignore. Gold continues to trade at historically elevated levels and antimony has surged on tightening supply and geopolitics. But the tailwind has a sting.
Siren Gold’s recently appointed chief executive officer Zane Padman.
As Siren’s Padman put it: “We have a clear pathway forward at Sams Creek and the funding to execute it. Stage one drilling will target the Carapace and South‑East Traverse zones, where mineralisation is shallow, accessible and will make up a large portion of any early‑stage mining. With antimony trading above US$60,000 (A$91,800) a tonne and gold above US$3300 (A$5000) an ounce, 1 per cent antimony in situ equates to about 5.5g/t gold.”
For a junior building optionality across gold and a critical mineral, the timing appears on point.
The near‑term work program is designed to do the heavy lifting on de‑risking. This is where the rubber hits the road: Siren expects a decision on its Sams Creek mining permit application by late this year. The current drill strategy aims to complete infill at Carapace, SE Traverse and the Main Zone by the end of June 2026, upgrading a substantial portion of inferred ounces to indicated. An updated mineral resource and a refreshed scoping study are slated to follow in the September quarter of 2026, incorporating new geotechnical, metallurgical and mine‑design inputs.
Padman said New Zealand’s West Coast is alive with exploration activity.
“Endura Mining - previously Federation - is attracting strong investment to advance the Snowy River mine under Jake Klein’s leadership, while Rua Gold holds the dominant land position across the region, encompassing several historic high-grade mines,” he said.
“In Otago, Santana’s Bendigo-Ophir project is shaping up to support more than 200 jobs at full production. Across the country, momentum is building rapidly, and Siren Gold is well positioned to be part of a resurging New Zealand mining sector that’s drawing global attention and serious capital.“
Corporate momentum has stepped up in tandem. Padman, who was appointed CEO last month, is a geologist and mining executive with more than 15 years of exploration and operations experience, including senior roles leading a turnaround at Westgold Resources’ Meekatharra operations. The placement terms -shares issued at 5c each - were well received and the stock has since traded above the placement price, a tidy endorsement for the company’s accelerated program.
It appears depth and leverage now round out the story. Siren still holds exposure to the consolidated Reefton and Hauraki belts through an equity stake of about 17 per cent in Rua Gold, offering it indirect leverage to ongoing North and South Island exploration without near‑term capital demands. Siren sold the Reefton project, then held by its former subsidiary Reefton Resource, to Canadian-listed Rua Gold for $22 million in November last year to consolidate the Reefton goldfields.
Closer to home, the company’s antimony‑rich satellites at Langdons and Queen Charlotte provide clear, shallow targets aligned with a critical‑minerals narrative that continues to gather steam in Western markets - squarely in the sweet spot for fresh drill‑bit news flow.
The bottom line is that next year is set up to matter. Land the Sams Creek permit on time, keep the core turning, and Siren starts to look like New Zealand’s next development‑ready gold system with district‑scale antimony‑gold upside waiting in the wings. From here, the brief is simple enough: convert ounces, publish the studies and let the grades do the heavy lifting. History says the market will follow.
