District Metals Corp (CVE:DMX) (OTCMKTS:MKVNF) (FRA:DFPP) revealed results of four drill holes from its Tomtebo project in Sweden, which included strong copper mineralization.
The results, from a maiden drill program on the property, were highlighted by 8.65 metres at 2.9% copper, 0.4 grams per ton (g/t) gold, including 7.05 metres at 3.47% copper and 0.52 g/t gold and 5.15 metres at 1.56% copper and 0.32 g/t gold in hole TOM21-013.
Another hole, TOM21-016, intersected 17.2 metres at 0.94% copper and 0.28 g/t gold, including 3 metres at 2.8% copper and 1.21 g/t gold.

The drill holes were sunk below open pits where copper sulphides were extracted at the Gårdsgruvans zone in the southwest portion of the historic Tomtebo Mine, according to a release. Both TOM21-013 and -016 successfully intersected vein networks of copper-rich sulphides within strongly altered felsic volcanic rocks, the company added.
Rodney Allen, District’s technical advisor, told investors that the company is interpreting the vein networks as “feeder conduits in which high temperature fluids carrying copper-gold-zinc-lead-silver” flowed upwards towards the sea floor in a submarine volcanogenic hydrothermal system.
Allen added that it is “likely” that the copper zones drilled in TOM21-013 and -016 represent cores of the sub-seafloor feeder system that continues upwards to feed massive sulphide mineralization at the Steffenbergs zone and other areas awaiting drilling.
“The widespread extent and the intensity of the copper-bearing vein networks indicate that Tomtebo has economic potential for both Cu-Au resources within the feeder vein system,” the company told shareholders.
Garrett Ainsworth, District’s CEO, called the results from the 5,611 metre, 22-hole spring 2021 program a “great success.”
"Our first few holes into the Gårdsgruvans zone have returned exceptionally strong copper results and associated alteration that exhibits the presence of multiple robust and long lasting copper-rich feeder zones, which is an important feature of other large polymetallic deposits in the Bergslagen District,” Ainsworth said.
“Our field personnel and Hy-Tech Drilling AB executed this drill program with the upmost professionalism.”
Permitting for the planned Phase II drill program in September or October 2021 has already started, Ainsworth added, telling shareholders that this pause in drilling will allow the company to “compile and interpret all of the newly obtained data to prioritize targets for an exciting Phase II drill program that will include large step outs and testing of regional targets up to a kilometer away from the historic Tomtebo Mine."
Tomtebo is located in the Bergslagen Mining District of south-central and comprises 5,144 hectares situated between the historic Falun Mine and Boliden's Garpenberg Mine.
