District Metals Corp. (TSX-V:DMX) has announced that it has commenced core drilling at its high-grade polymetallic Tomtebo property located in the Bergslagen Mining District in south-central Sweden.
The Vancouver-based developer of prospective mineral properties said GEOPS-Bolkan Drilling Services Ltd has been awarded the contract for the drill program, which will comprise 1,200 metres (m) in three holes, followed by drilling 1,800m in 10 holes at the Gruvberget property located 40 kilometres (km) northwest from Tomtebo.
Drill permitting for 800m in two holes at the company’s Bakar Copper property on Northern Vancouver Island continues and drilling may commence in June or July 2022, District Metals added.

"We continue to increase our understanding of the high grade polymetallic mineralized system at the historic Tomtebo Mine through the utilization of modern exploration techniques,” CEO Garrett Ainsworth said in a statement. “This phase of drilling will test some very exciting targets identified from our work to date. By way of example, the massive sulphide lenses at the Steffenburgs zone intercepted by our drilling in 2021 have returned significant widths of high-grade polymetallic mineralization that remain open in many directions. We are also keen to aggressively step out from the Tomtebo Mine with this current drill program, to further assess one of the numerous other coincident geophysical targets outside of and along trend from the Tomtebo Mine that remain untested.”
District Metals said the primary objectives of the Tomtebo property drill program include:
- Two step out holes below high-grade polymetallic mineralization at the Steffenburgs zone, where its recently reported hole TOM21-028 intersected 30m at 10.9% zinc equivalent, to test for potential extensions of the massive sulphide lenses at depth.
- An aggressive 665m step out northeast from the historic Tomtebo Mine at a virgin regional target to test a magnetic high anomaly along the Tomtebo Mine Volcanogenic Massive Sulphide (VMS) mineralized horizon. The magnetic high anomaly at this target has a similar signature to the magnetic high associated with polymetallic mineralization at the Steffenburgs zone. The location of the favourable VMS mineralized horizon has been established through the use of whole-rock geochemistry that connects the Oscarsgruvan zone to regional drill hole TOM21-023B, which was drilled 1km northeast along trend from the Tomtebo Mine.
The Tomtebo project in the Bergslagen mining district of Sweden is District Metal's main exploration focus.
Tomtebo comprises 5,144 hectares and sits between the historic Falun mine and Boliden's Garpenberg mine, which are 25km to the northwest and southeast, respectively.
Two historic polymetallic mines and numerous polymetallic showings are located on the Tomtebo Property along an approximate 17km trend that exhibits similar geology, structure, alteration and VMS/SedEx style mineralization as other significant mines within the district.
