Siren Gold Limited has advanced its New Zealand gold and antimony projects with a major drilling campaign at Sams Creek and promising exploration results at Queen Charlotte, while navigating regulatory hurdles.
- 7,000m diamond drilling underway at Sams Creek to upgrade 824koz gold resource
- High-grade gold and antimony assays confirm extensive mineralisation at Queen Charlotte
- Langdons project exploration footprint expanded with new gold-antimony anomalies
- Siren receives AU$1.6M tranche 2 from AU$4M capital raise to fund activities
- Mining permit application for Sams Creek progressing amid judicial review challenge
Steady Progress at Flagship Sams Creek
Siren Gold Limited (ASX – SNG) has reported solid advancement across its New Zealand portfolio during the December 2025 quarter, with a particular focus on its flagship Sams Creek Gold Project. The company commenced a substantial 7,000-metre diamond drilling program aimed at upgrading and expanding its existing Mineral Resource Estimate of 824,000 ounces at 2.8 grams per tonne gold. This drilling targets both infill to convert inferred resources to indicated status and step-out holes to test extensions, including maiden drilling at the promising Doyles Fold target.
The Sams Creek mineralised system remains one of New Zealand’s largest undeveloped gold resources, hosted within a steeply dipping porphyry dyke extending over seven kilometres along strike and more than one kilometre down dip. Despite this scale, less than 15% of the dyke has been systematically drill tested, leaving significant upside potential. The ongoing drilling campaign is expected to underpin an updated Mineral Resource Estimate and Scoping Study, key milestones for advancing the project towards development.
Encouraging Exploration at Queen Charlotte
Exploration activities at the Queen Charlotte Gold and Antimony Project have confirmed extensive mineralisation along a 1.5-kilometre section of the 12-kilometre Endeavour Shear Zone. Surface mapping and sampling returned multiple high-grade gold and antimony assays from both channel and rock chip samples, with standout results including 6.0 metres at 2.9 g/t gold and 1.0% antimony from the Maria Reef, and 1.2 metres at 1.5 g/t gold and 18.5% antimony from the Skyline Reef.
The historic Endeavour Inlet Mine extends approximately 1,500 metres in strike and over 400 metres vertically, with mineralisation likely to continue at depth. These findings reinforce Siren’s view of Queen Charlotte as a district-scale opportunity with significant strategic value, particularly given antimony’s rising importance as a critical mineral in energy storage and high-tech industries.
Langdons Expansion and Strategic Funding
At the Langdons Gold and Antimony Project, soil geochemistry has identified new gold-antimony anomalies, extending mineralisation along strike and beneath cover. The granting of a five-year Exploration Permit provides a clear pathway for future drilling. Siren continues to integrate geological and geochemical data to prioritise drill targets, with environmental approvals underway.
Financially, Siren received AU$1.6 million in tranche 2 funds from a previously announced AU$4 million capital raise, supporting ongoing exploration and development activities. The company ended the quarter with a cash balance of AU$3.4 million after spending AU$561,000 on exploration and evaluation.
Regulatory and Legal Landscape
Siren’s Sams Creek Mining Permit application remains under review by New Zealand Petroleum & Minerals (NZPAM). The company continues to meet all procedural and technical obligations while advancing drilling and exploration. However, Siren has been served with a judicial review notice challenging decisions related to the mining permit application and appraisal extension. The company regards the proceedings as lacking merit and intends to defend vigorously.
Despite this legal challenge, Siren remains encouraged by recent government initiatives to streamline mineral sector regulation in New Zealand, which have seen peers progress through permitting processes. This regulatory momentum aligns with broader efforts to promote mining and infrastructure development, supporting employment growth.
Looking Ahead
As Siren enters the March 2026 quarter, operational momentum is strong. Drilling at Sams Creek continues to provide critical data for resource and scoping updates. Exploration at Queen Charlotte will expand surface mineralisation evaluation, with preparations underway for maiden drilling. Langdons is progressing towards drill readiness, supported by comprehensive geological modelling and environmental permitting efforts.
Overall, Siren Gold is advancing its projects with a disciplined approach, balancing exploration progress with regulatory and environmental responsibilities, positioning itself to unlock value in New Zealand’s gold and antimony sectors.
Bottom Line?
Siren Gold’s drilling and exploration momentum faces a pivotal test as regulatory and legal challenges unfold, shaping the path to project development.
Questions in the middle?
- How will the judicial review impact the timeline for Sams Creek’s mining permit approval?
- What are the potential production targets once the inferred resources at Sams Creek are upgraded?
- Can Queen Charlotte’s high-grade antimony and gold mineralisation translate into a viable mining operation?
