The Bleikvassli project is located in central Norway. The project contains the Bleikvassli mine which closed in 1997 and produced ~5 Mt averaging 4.0%Zn, 2% Pb, 0.15%Cu, and 25g/t Ag*.
The host rocks consist of amphibolite grade, Nordland facies supracrustal rocks (schists, carbonates, quartzites, and amphibolites). Clear zoning patterns and hangingwall/footwall relationships with identifiable K-silicate alteration zones and redox horizons (analogous to the Zinkgruvan deposit in Sweden) are present. These patterns can assist in vectoring toward mineralization.
Precious metal contents have never systematically been assessed at Bleikvassli and there are still large, un- or under-explored areas within the project.
Three types of mineralization are seen at Bleikvassli; massive pyritite (Zn-Pb-Cu), massive phyrrotite (Cu-rich), vein/disseminated wall-rock mineralization (with native Ag/Au).
A share purchase agreement to sell the project to Norra Metals Corp. (formerly OK2 Minerals) (TSX-V: NORA) was executed in December 2018 for an equity interest equity in Norra, annual advance royalty (“AAR”) payments, and a retained 3% royalty interest. (see Company news releases dated December 13, 2018 and February 19, 2019).
* Geological Survey of Norway Ore Database, Deposit Area 1832-012. EMX has not performed sufficient work to verify the published assay data reported on this slide, and these data cannot be verified as being compliant with NI43-101 standards. These historically reported data should not be relied upon until they can be confirmed. However, the mineralization as reported in various public documents available online and from the NGU (Norwegian Geological Survey) is considered reliable and relevant.
Note: The nearby mines and deposits mentioned above provide context for EMX’s Project, which occurs in a similar geologic setting, but this is not necessarily indicative that the project hosts similar tonnages or grades of mineralization
