Arctic Minerals has extended visible copper mineralisation beyond the existing resource at its Hennes Bay copper-silver project in Sweden, with follow-up drilling now targeting the potential expansion of the mineralised system.
The Nasdaq First North-listed explorer completed a 4,187-metre maiden drilling programme, with 10 of 12 holes intersecting visible copper mineralisation. Several step-out holes encountered mineralisation as far as 600 metres from historical drilling. Hennes Bay currently hosts a JORC Inferred resource of 55.39 million tonnes grading 1.0% copper equivalent, based on 0.8% copper and 20.8 grams per tonne silver. The estimate contains approximately 447,000 tonnes of copper and 36.99 million ounces of silver.
Drilling expands exploration footprint
The existing resource covers only the Dingelvik prospect, while seven of the new mineralised holes were drilled at Åsnebo, Baldersnäs, Henneviken and Asslebyn, outside the current resource area. Three additional holes at Dingelvik tested extensions reaching approximately 500 metres east and south of the existing resource model.
The results indicate that copper mineralisation extends across several targets, raising the possibility of a broader sediment-hosted copper district at Hennes Bay. The visual observations do not establish the grade or economic significance of the mineralisation. Laboratory assays from the maiden programme are therefore expected to determine whether the newly identified extensions can support additional resources.
Arctic Minerals launches 8,000-metre programme
Arctic Minerals has already begun a second drilling campaign consisting of approximately 20 holes and 8,000 metres. The programme will investigate regional anomalies identified through 2025 geophysical surveys and test areas that remain largely unexplored. The company estimates that less than 5% of the prospective sediment-hosted copper horizon across its approximately 414-square-kilometre land package has been drill tested. This leaves substantial exploration ground outside the current resource and recently drilled areas.
Assays will determine resource expansion potential
The next stage for Hennes Bay will depend on whether assay results confirm copper grades comparable with those supporting the existing Dingelvik resource. Consistent grades across the newly drilled areas could provide a basis for expanding the resource footprint, while the project’s significant silver content could potentially contribute additional value as a by-product. The immediate focus is on assay results from the 4,187-metre maiden programme, followed by results from the new 8,000-metre drilling campaign.
For Arctic Minerals, the key objective is to establish whether the mineralisation identified beyond Dingelvik can translate into additional copper and silver resources and strengthen the project’s longer-term development potential.
