EMX’s Åkerberg project is located at the eastern end of the Skellefte VMS belt 35 Km northwest of Skellefteå. The east-west trending Skellefte VMS trend ends at a tectonic break where there is a north-south trending zone which is highly prospective for gold. This tectonic break is part of a lithospherical boundary which rheologically indicative of a deep-reaching structure corridor. At Åkerberg the gold occurs in east-west trending cm-scaled en echelon sheeted quartz veins hosted in a crudely layered gabbro. The mineralized zone is ~10–30 m wide and ~350 m long, and can be followed to a depth of around 150m.1 The gold occurs in the quartz veins as well as in vein margins and wall rock, in association with sheelite.
Potential of additional mineralization remains along strike west of the historic Åkerberg mine. The Åkerberg mine closed in 2001 at due to a 20 year-low gold price. Prospective settings could be found along the contact between the gabbro and the granodiorite, as well as within associated vein sets. The association with sheelite could help with the targeting as a marker material. It can be observed by using UV-light and handheld XRF in the field.
