The Falun Projects in Bergslagen, South-central Sweden
Outline Executive Summary The Bergslagen District The Falun Copper Mine Company activities / Claims Samuelsdal Holmen Mårtanberg The Scandinavian Highlands Group
Executive Summery - Activities in the highly prospective NW Bergslagen Scandinavian Highlands holds 8 licences covering 165 km 2 in NW Bergslagen. A deep ore body (Zn, Pb, Cu) is situated within our near-mine licence in Falun. A potential continuation of the Falun mine Au-Cu ore has been identified towards the SE. Large airborne TEM / MAG anomaly has been identified within our licence area 7 km SW of Falun. A newly acquired licence holds significant potential for VMS deposits.

The Falun Copper Mine - Summary During centuries the Falun mine was of major strategic importance for Sweden. The mine closed in 1992 after more than 1000 years of continuous mining and was among the largest gold deposits in Sweden. The Falun Mine is now preserved as an UNESCO World Heritage Site.

The Falun Area - Samuelsdal target N
The Falun Area - Samuelsdal target The exploration carried out by Scandinavian Highlands indicate a potential continuation of the Falun mineralisation within the poorly explored area of Samuelsdal Soil sample geochemistry with anomalous high Au-Cu-Zn-Pb values. Both airborne and ground based geophysics suggest mineralisations in a SE strike from the Falun mine. Favourable geology on surface and deep drill cores. High grade Copper Mineralisation in outcrops. Encouraging drill results, with local Bonanza grades only 300 m from our licence area.

Holmen - A potential blind sulphide deposit New modern geochemistry and geophysics outline a significant target at Holmen Airborne TEM and MAG has identified a large TEM anomaly associated with a major structural lineament. Ground based magnetic confirm the airborne target. Geological observations suggests a large scale fold enclosing the potential mineralisation, suggesting favourable geology for mineralisation. Soil Gas Hydrocarbon (SGH) survey confirming the potential mineralisation. Drill target indentified.
