EMX’s Tomtebo Zn-Pb-Cu-Ag project is a large land position in the heart of the prolific Bergslagen VMS District of southern Sweden. Extensive workings and dumps across the property testify to eight centuries of metals production, most from depths much less than 200 meters. The extent of this known mineralization has not been explored with modern methods. Stockholm is about three hours south, and the industrial center Borlange is about 15 kilometers west. Tomtebo is situated 25 Km southeast of the World Class Falun polymetallic VMS mine and 25 Km northwest of Boliden’s rapidly expanding Garpenberg Zinc Mine.

Tomtebo has similar host rocks to both Falun and Garpenberg: strata-bound, syn-volcanic skarn and carbonate replacements, associated with mafic to felsic volcanics. VMS mineralization occurs as sulfide-lenses and rods along a ~15 kilometer trend. Carbonate replacement deposits, base metal replacements and skarn alteration are also present.

Past production at Tomtebo is not known with certainty, but is estimated at: 0.12Mt @ 4.4% Cu at Tomtebo Mine and 0.33Mt @ 2.5%Pb, 3.5%Zn, and 30 g/t Ag from “Lövås” (Nyberget Mine). Detailed historic reports, maps and cross sections are available.

EMX is encouraged by these grades and believes modern exploration methods can vector toward additional mineralization over mineable widths. 

EMX sold the Projects in Sweden to District Metals Corp. (TSX-V: DMX). The agreement provides EMX with a 9.9% equity interest in District, annual advance royalty payments, 2.5% Net Smelter Returns (“NSR”) royalty interests in the Projects, and other considerations.

*Nearby mines and deposits provide context for the project, but do not necessarily indicate similar size, styles or grade of mineralization within the project.

Note: EMX has not performed sufficient work to verify the published assay data reported above, 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 SGU (Swedish Geological Survey** Geological Survey of Sweden report grb_097, 1997.) is considered reliable and relevant.
