About Viscaria

Gruvaktiebolaget Viscaria is a company that is scaling up to become a modern and responsible producing mining company through the reopening of the Viscaria mine in Kiruna. The deposit's high copper grade, assessed mineral resources, geographical location and growing team of experienced employees provide good conditions for the company to become an important supplier of high-quality and responsibly produced copper - a metal that has a central role in Sweden's and Europe's climate transition. In addition to the Viscaria mine, the company holds a number of processing concessions and exploration permits in Arvidsjaur (Eva, Svartliden, Granliden) and Smedjebacken (Tvistbogruvan) - all in Sweden. The Parent Company's shares are listed on Nasdaq Stockholm Main Market (ticker VISC).
