District Metals Corp (CVE:DMX) (OTCMKTS:MKVNF) told investors that an airborne electromagnetic (EM) and magnetic survey had started on its 5,144 hectare Tomtebo project - the first time a deep penetrating airborne study has been carried out at the site.
The Bergslagen district in Sweden is known for large high grade polymetallic mineralized systems and the lack of EM and detailed magnetic coverage is astounding, said Garrett Ainsworth, the chief executive at District in a statement.

"The recently commenced SkyTEM312 HP survey represents the first time a deep penetrating airborne EM survey (greater than 200 meter depth) has been carried out on the Tomtebo Property.
"This is significant because we know that these systems in the Bergslagen Mining District can have mineral resources from surface to depths of 1600 meteres, such as is the case at Boliden's Garpenberg Mine and Lundin Mining's Zinkgruvan Mine."
The Vancouver-based explorer has been analyzing historic drill data on the past-producing project and has already identified a number of highly prospective targets.
It is expected that the airborne survey by Danish group SkyTEM Surveys ApS will identify the copper-gold dominant sulphide mineralization as feeder zones while the silver-zinc-lead sulphide mineralization will be distal zones.
However, notably the silver-zinc-lead mineralization in the district often has associated magnetic sulphides, which is expected to be detected as a moderate to strong magnetic high, said District.
The survey will cover the entire Tomtebo property with around 600 line-kilometers at a line spacing of 100 metres, and is capable of detecting conductive polymetallic sulphide mineralization at depths of 500 metres or more.
