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 additional mineralised zones across the property.
The Nasdaq First North-listed explorer completed a maiden programme of 4,187 metres across 12 holes, with 10 holes intersecting visible copper mineralisation. Step-out drilling reached 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, comprising 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.
Mineralisation Extends Beyond Existing Resource
The current resource covers only the Dingelvik prospect, while seven holes containing visible copper were drilled at Åsnebo, Baldersnäs, Henneviken and Asslebyn, outside the existing mineral-resource estimate. At Dingelvik, three mineralised holes tested extensions reaching approximately 500 metres east and south of the current resource model.
The results indicate that copper mineralisation extends beyond the area currently included in the resource, although the potential for additional resources remains subject to laboratory assays. Arctic Minerals has stressed that visible sulphides cannot be used to estimate copper grades. Assay results from the maiden campaign are expected in roughly one month.
New 8,000-Metre Programme Targets Regional Anomalies
The company has already commenced a second drilling campaign consisting of approximately 20 holes covering 8,000 metres. The programme will test regional anomalies identified through 2025 geophysical work and investigate whether mineralisation continues into largely unexplored areas of the project.
Arctic Minerals estimates that less than 5% of the prospective sediment-hosted copper horizon across its approximately 414-square-kilometre land package has been tested by drilling. The existing Hennes Bay resource also contains a substantial silver component, with 36.99 million ounces of contained silver, alongside the copper inventory. The immediate focus is on assay results from the completed 4,187-metre programme and further drilling evidence from the 8,000-metre campaign across multiple prospects.
