EMX’s Koberg and Långban projects are located in the historic Bergslagen district approximately 200 km west of Stockhom. The Bergslagen district is one of Europe’s oldest mining districts with centuries of mining history (e.g., Falun Mine).

The projects are within Svecofennian (1.9-1.8 Ga) metavolcanic and metasedimentary sequences and are the same host rocks as the Garpenberg (Boliden) and Zinkgruvan (Lundin) mines. There are also younger granitic rocks and local mafic/ultramafic intrusive rocks (1.8 – 17.7 Ga). Carbonate rocks contains massive base metal sulfide mineralization and are associated with skarns and are typically along bedding horizons.

At Koberg, late 1970’s exploration for lead-zinc-tungsten focused on the southeastern end of the license area. Limited diamond drilling was also conducted that focused on IP targets that were explained by features encountered before bedrock was intercepted. Some drilling also occurred in the late 1990’s for lead-zinc. Targets at Koberg focused on Mn-rich iron ore, while adjacent carbonate units exhibit zones of massive sulfide.

Långban is a historic mining center (1711-1972) focused on iron and manganese. Recent exploration includes 1990’s drilling by NGU and drilling by Wiking Minerals and Drake Resources in the 2000’s.

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.
