District Metals Corp (CVE:DMX) (OTCMKTS:MKVNF) (FRA:DFPP) has kicked off a 5,000 metres (m) drill program at its Tomtebo property, focusing on the historic mine area, where high priority targets have been identified.
The company said 21 holes are planned, with a focus on the Oscarsgruvan, Steffenburgs, Gårdsgruvans, and Gamla Gruvans zones.

Garrett Ainsworth, the group's CEO said in a statement: "This is an exciting time for the company and our shareholders as we embark on the first substantial drill program at the Tomtebo Mine in almost half a century.
"The potential of the Garpenberg Mine did not get unlocked until the 1990's, and now we are applying that knowledge and technology at Tomtebo. Our geological interpretations from work carried out in late-2020 greatly contributed to firming up our drill targets, and the subsequent implications from these interpretations are very encouraging.
"A key to this successful outcome has been the involvement of Rodney Allen and Hein Raat, who are both well-known experts in the Bergslagen Mining District. With a better understanding on the controls of polymetallic mineralization and the structural framework at the Tomtebo mine, we have started our maiden drill program fully armed with knowledge to optimize every meter drilled."
The program will follow up, infill, and step out from previous significant high-grade polymetallic mineralization encountered.
Borehole electromagnetic surveys (BHEM) will be conducted on all holes, which is an important modern technology used to detect "off-hole" conductive sulphide mineralization.
Tomtebo spans 5,144 hectares (ha) and lies between the historic Falun mine and Boliden's Garpenberg mine, which lies 25 km to the northwest and southeast, respectively.
Two historic polymetallic mines and numerous polymetallic showings lie at the asset, along an approximate 17km trend.
District outlined the strategy for each of the zones thus:
- Oscarsgruvan and Steffenbergs Zones: targeting silver-zinc-lead sulphide mineralization in skarn-altered limestone beds, and veins of remobilized massive sulphide within felsic volcanic rocks. Numerous sections of this stratigraphic horizon have not been drilled. In addition, targeting will focus on the extensions of massive sulphides intersected in the historical drill holes that coincide with conductive and magnetic high anomalies;
- Gårdsgruvans and Gamla Gruvan Zones: targeting copper-gold vein networks and strong disseminations within and adjacent to zones of strong alteration. This includes the extension of this alteration zone at depth and to the southwest of Gårdsgruvans. In addition, Rödbergsgruvan (located south of Gamla Gruvan) is a priority area to drill test with historical mineralized drill intercepts and coincident conductive and magnetic anomalies; and
- Björngruvan Zone: targeting historical silver-zinc-lead and copper-gold drill intercepts coincident with conductive and magnetic anomalies that are located adjacent east of Oscarsgruvan. This will also provide important information on the stratigraphy, structure and alteration pattern at the inferred eastern "limb" of the polymetallic system at the Tomtebo Mine.
