The Stekenjokk and Levi projects are on the border between Västerbotten and Jämtland counties and close to the Norwegian border. Discovery was made in 1918 by the Swedish Geological Survey (SGU). Stekenjokk was in production by Boliden between 1976 and 1988 and about 7.1 Mton of ore with grades around 1.5% copper and 3.5% zinc was produced. Stekenjokk and Levi are since 2012 classified as Nationally Interest for minerals.
Stekenjokk and the Levi consist of three different mineralisations: Stekenjokk North which was mined during the previous period, and Stekenjokk South and Levi which have not been mined. Based on previous drilling, total remaining assets are estimated to 7.4 Mton of indicated mineral resources with 1.17% copper and 3.01% zinc and 2.7 Mton of inferred resources with 0.94% copper and 2, 95% zinc.
The application for exploitation concession was supplemented with an alternative solution in 2017 after Vilhelmina Mineral invested in Joma (located approximately 60 km from Stekenjokk). This investment enables a secondhand alternative with seasonal underground mining during winter in Stekenjokk and the ore then transported to Joma for processing and deposit.
