Hirsikangas (Central Finland)

The Hirsikangas deposit in Central Finland is a Palaeoproterozoic orogenic gold deposit located on a 30km crustal scale shear zone. Using a 0.5 g/t cut off grade, Hirsikangas has Indicated mineral resources of 3.002 Mt at a grade of 1.23 g/t Au (119koz) and Inferred mineral resources of 2.673 Mt at a grade of 1.27 g/t Au (106koz) (collectively, the “Hirsikangas Resources”). These resources are contained within 1.2km of strike length and drilled at shallow levels. The prospect, that outcrops at surface, is open down dip and along strike in both directions and there is evidence of a potential parallel structure.

Since 2016, the geological team working at Hirsikangas has expanded the licence package from the small exploration permits hosting the current Hirskangas resource to cover the entire 30km strike of the indicated shear zone and potential parallel structures (see Figure below). In the first season of fieldwork under NARL’s ownership, a sampling and mapping campaign was begun to cover the strike extent of the shear zone and yielded a number of gold bearing outcrops, boulders and soil anomalies. This work will continue in the summer season of 2018. The Hanni target located south east along strike from the Hirsikangas deposit has previously been identified by the Geological Survery of Finland (GTK) and has some limited historic drilling, along with IP geophysics. NARL has applied for an exploration permit covering the extent of the target and undertaken stakeholder meetings with landholders and local authorities to discuss its exploration plans for the area. The figure below shows the extent of the historic sampling along with work by NARL’s team in 2017 and the widespread distribution of anomalous boulders throughout the reservation area along the Ruhanperä shear zone. Samples collected from boulders grading 21 g/t Au, 24 g/t Au and 110 g/t Au were found by prospectors close to the Hanni target (these samples are selected samples and are not in-place and are not representative of the mineralization hosted on the property).
