VANCOUVER, Dec. 1, 2017 /CNW/ - Boreal Metals Corp. ("Boreal" or the "Company") is pleased to announce that exploration drilling is underway at its 100% owned Gumsberg license property located in the prolific Bergslagen Mining District in southern Sweden (Figure 1).
Boreal plans to conduct 2,500 meters of diamond drilling across three prospective high grade volcanogenic massive sulphide ("VMS") mineral trends including Östrasilvberg, Vallberget-Loberget and Gumsgruvan. Each of these silver-zinc-lead trends contain historical drilling from the 1930s and 1970s (Table 1) and mining activities that can be traced to medieval times.
"Boreal has successfully advanced three high grade mineralized trends within the 18,300 hectare Gumsberg land position to the drill testing phase," stated President and CEO Karl Antonius. "We are excited to see the results of the 2017 Drill Program given the high grades intercepted on the property by EMX Royalty Corp. in 2016".
The strategically situated Gumsberg project consists of six exploration licenses in the Bergslagen Mining District of southern Sweden totaling over 18,300 hectares, where multiple zones of VMS style mineralization occur. The VMS mineralization at Gumsberg was mined from the 13th century through the early 1900s, with over 30 historic mines present on the property, most notably the Östrasilverberg mine which was the largest silver mine in Sweden between 1250 and 1590. Despite its long lived production history, relatively little modern exploration has taken place on the project. New geologic interpretations, geophysical surveys and reconnaissance drilling by EMX Royalty Corp. have led to the identification of multiple exploration targets, near the historic workings.
About Boreal Metals Corp.
Boreal is a mineral exploration company focused on the discovery of Zinc, Copper, Silver and Gold deposits in four exceptional, historical mining project areas spanning Sweden and Norway. The Company aims to discover new economic mineral deposits in known mining districts that have seen little or no modern exploration techniques. The Company is led by an experienced management team and technical team, with successful track records in mineral discovery, mining development and financing.

Table 1. Selected high grade historical drill intercepts from the Gumsberg Project. Boreal has not performed sufficient work to verify the published drill data reported in this table. These historically reported data should not be relied upon until they can be confirmed. However, the drill-delineated mineralization as reported in various public documents available online and from the SGU (Swedish Geological Survey) is considered relevant.
