Langdons Exploration Hinges on Permit Approval Amid High-Grade Gold-Antimony Finds

Siren Gold reports compelling high-grade gold and antimony assay results from its Langdons Project in New Zealand, confirming significant mineralisation and setting the stage for its maiden drilling program.

  • Gold grades up to 38.5 g/t and antimony up to 20.9% from recent sampling
  • Mineralised structures extend over 400m strike with potential extensions under cover
  • Historical mining recorded exceptional gold grades up to 2,610 g/t
  • Exploration permit application submitted, enabling upcoming drilling
  • Ongoing surface exploration to refine drill targets and expand geochemical footprint

Exploration Revival at Langdons

Siren Gold Limited (ASX – SNG) has delivered a promising update on its Langdons Antimony-Gold Project, situated in the Paparoa Goldfield of New Zealand. The company’s recent fieldwork, conducted in August 2025, has revealed very high-grade gold and antimony mineralisation in historic mining areas last active in the 1950s. These results reinforce Langdons’ reputation as a site of exceptional mineral potential, with assays returning gold grades as high as 38.5 grams per tonne and antimony concentrations reaching 20.9%.

Significant Mineralisation Confirmed

The recent sampling campaign included detailed mapping, rock chip, and channel sampling across exposed reefs and historic workings. Multiple mineralised structures have been identified extending over a 400-metre strike length to the northwest, with soil geochemistry suggesting the mineralisation continues beneath cover rocks and potentially extends northeast. Notably, mullock samples from the No.2 Adit and Shaft returned standout grades, underscoring the high-grade nature of the mineralisation.

Historical Context and Strategic Value

Langdons has a rich mining history, with early records showing gold grades up to 2,610 g/t and significant antimony presence. The project’s dual focus on gold and antimony is strategically important, as antimony is increasingly recognised as a critical mineral with growing global demand and supply chain interest. Siren Gold’s CEO, Zane Padman, highlighted this strategic dimension, noting that the company is rapidly advancing geological understanding and preparing for its maiden drill program to unlock further value.

Pathway to Drilling and Future Work

Siren Gold has submitted an exploration permit application, which once granted, will allow the company to progress to drilling, subject to environmental approvals. Meanwhile, ongoing surface exploration activities such as soil geochemistry, trenching, and mapping continue to refine drill targets and expand the footprint of known mineralisation. The integration of all data into a comprehensive 3D geological model is expected to enhance targeting precision for upcoming drilling campaigns.

Outlook

The Langdons Project stands at an exciting juncture, combining historical high-grade mineralisation with modern exploration techniques and strategic critical mineral exposure. Siren Gold’s methodical approach to unlocking this goldfield’s potential could position the company well in the evolving gold and critical minerals markets.

Bottom Line?

As Siren Gold awaits permit approval, the Langdons Project’s high-grade results set the stage for a pivotal drilling phase that could reshape its resource outlook.

Questions in the middle?

  • When will the exploration permit be granted and drilling commence?
  • How representative are the mullock sample assays of in situ mineralisation?
  • What is the potential scale and continuity of the mineralised system beneath cover?
