EMX's Slättberg project is located 25 kilometers northwest of Falun, Sweden. Slättberg is a historic mining camp hosting Ni-Cu-Co rich massive sulfide mineralization that occurs within a two kilometer belt of historic nickel-copper mines. The property contains drill defined massive sulfide mineralization that extends to ~100 meters in depth, and remains open for expansion at depth and along strike. Gold enrichment of the mineralized zones was confirmed by historic assays, but has not been followed-up. The Slättberg project is available for partnership.
The massive sulfide lenses exposed in historic mine workings pinch and swell along strike, with mineralization also occurring as chalcopyrite-rich quartz vein material as seen in several mine dumps. Analyses of historic drill core using a hand-held XRF* unit indicate enrichments of zinc to the nickel-copper mineralization. Although Slättberg is commonly listed as a platinum group (PGE) occurrence in Swedish publications (along with Ni, Cu, and Co), only limited assaying has been performed for PGE mineralization.
The mineralization at Slättberg is hosted by 1.8-1.9 Ga (Svecofennian) supracrustal rocks (metavolcanics and metasediments) located at the southern margin of a gabbroic intrusive complex. Rock types observed in the mine dumps include rhyolitic tuff, metasedimentary rocks, diabase and diorites.
EMX believes that given the historic mine activity, limited shallow historic drilling, gold mineralization that has yet to be followed-up, and the unassessed PGE potential that there is high potential for exploration discovery at Slättberg.
Note: The nearby mines and deposits in the region provide context for EMX’s Project, but this is not necessarily indicative that the Project hosts similar mineralization.
*XRF analyses are collected with a portable XRF device from rock surfaces that have not been pulverized or homogenized in any way. The XRF results are to be considered estimates and have not been independently checked with a certified laboratory, but are considered to be relevant and reliable.
