Svärdsjö

The Svärdsjö project is located in the world-class Bergslagen mining district. The project has similar geologic features as the famous Garpenberg Mine*. The project area has been actively mined for over 500 years with historic production of 1.04 Mt @ 0.6% Cu, 1.5% Pg, 4.5% Zn, and 0.4 g/t Au1.

The geology in Svärdsjö is strata-bound, dolomitic marble hosted, altered to skarn surrounded by heavily altered (hydrothermal and metamorphic) subvolcanic intrusions and volcanoclastics. Regional magnetics indicate a series of highly magnetic anomalies coincident with base metal occurrences that form a ring structure around a volcanic center. Other deposits in Bergslagen (Falun, Lovåsen (Tomtebo) and Trollberget)  occur on similar ring-type structures around volcanic centers.

*Nearby mines and deposits provide context for the project, but do not necessarily indicate similar size, styles or grade of mineralization within the project.
