Stekenjokk and Levi

The Swedish subsidiary Vilhelmina Mineral AB (publ) is active in exploration and mine development in the Nordic region with a focus on base metals, primarily copper and zinc. The goal is to develop the current deposits and start mining operations within the next few years. The main projects consist of the Swedish projects Stekenjokk and Levi in ​​Västerbotten and the Norwegian project Jomafälten located in Trøndelag. During the period 1976 to 1988, a total of approximately 7 million tonnes of ore was mined by operator Boliden in Stekenjokk. It is estimated that there is a remaining indicated mineral resources of approximately 7.4 million tonnes with concentrations of 1.17% copper, 3.01% zinc and 47 gram per tonne of silver (at cut-off content 0.9% copper). For Stekenjokk and Levi, an application for a exploitation concession has been submitted to the Swedish authorities. According to the application, underground mining will be conducted in the winter in Stekenjokk and the ore will then be transported to Joma for processing and tailings handling.
