The Del Norte (Kosciuzsko, K Zone) occurrence is located 34 kilometres east of Stewart and approximately 9 kilometres southwest of the west end of Meziadin Lake. Teuton Resources Corp. personnel discovered it in 2002 at the edge of a wasting ice field.

The area is underlain by north-striking(?) Lower Jurassic Betty Creek Formation(?) rocks (Hazelton Group; Bulletin 63). These rocks comprise predominantly plagioclase porphyry andesites that are interbedded with intermediate tuffs and volcaniclastics. Argillite, sandstone and siltstone form thin bands in the volcanics. Northwest-trending, northeast-dipping plagioclase and hornblende porphyritic dikes of the Portland Canal dike swarm intrude all rock types, especially in the area north of the Del Norte Glacier. Northeast–, north to north-northwest– and east-northeast–trending faults have been reported in the area.

Locally, quartz-feldspar-sulphide replacement zones, veins and quartz-carbonate-feldspar-sulphide cemented breccia occur within argillite of the Salmon River formation, Stewart Complex. The zone is exposed over a north-northwest strike length of 50 metres, varies from 3 to 10 metres wide and dips 60 degrees northeast. Sulphides include pyrite, sphalerite, galena and lesser tetrahedrite, up to 15 per cent. Native gold has also been reported in drillcores. The zone is not part of the nearby LG (MINFILE 104A 161) vein and is located some 60 to 70 metres northeast from the presumed location of the vein.

In 2002, chip sample across the northern end of the zone returned a 10-metre width with a weighted average grade of 6.14 grams per tonne gold and 630.86 grams per tonne silver (Teuton Resources Corp. News Release, September 26, 2002). Later that year, a drillhole (DN02-03) yielded 7.64 grams per tonne gold and 277 grams per tonne silver over 23.4 metres (Mastalerz, K., Walus, A. [2020-03-31]: National Instrument 43-101 F-1 Technical Report on Del Norte Property).

Later work (2006 and 2019), identified the possible southward extension of the LG (MINFILE 104A 161) vein at two separate sites, referred to as the SP vein and Crest zone, located several hundred metres south of the main Kosciuzsko (K Zone) occurrence. The SP vein has been traced for 40 metres along a north-northwest strike and is approximately 1.1 to 1.2 metres wide with a dip of 75 to 85 degrees to the west-southwest. The vein is locally heavily mineralized with pyrite, galena, sphalerite, arsenopyrite and chalcopyrite. The sulphides are commonly concentrated along 0.2- to 0.3-metre–wide zones along the contact of the vein.

In 2006, a surface grab sample from the SP vein yielded 19.5 grams per tonne gold and 3910 grams per tonne silver, whereas drilling yielded intercepts of up to 26.54 grams per tonne gold and 1208 grams per tonne silver over 1 metre (76.3 to 77.3 metres down hole) in hole D06-11 (Mastalerz, K., Walus, A. [2020-03-31]: National Instrument 43-101 F-1 Technical Report on Del Norte Property).

In 2019, a 1.10-metre chip sample (A19-258) taken across the SP vein assayed 6.59 grams per tonne gold, 91.4 grams per tonne silver, 2.06 per cent lead and 2.01 per cent zinc, whereas a 0.30-metre chip sample (DNK19-5) taken from a banded, 0.10- to 0.12-metre-wide, quartz vein assayed 19.6 grams per tonne gold, 3920 grams per tonne silver, 0.58 per cent copper, 1.91 per cent lead and 0.47 per cent antimony (Mastalerz, K., Walus, A. [2020-03-31]: National Instrument 43-101 F-1 Technical Report on Del Norte Property). The banded quartz vein is subparallel to and approximately 2 to 3 metres east of the SP vein. Also at this time, sampling of the Crest zone yielded up to 0.46 gram per tonne gold, 25.8 grams per tonne silver and 0.15 per cent lead (Sample A19-260; Mastalerz, K., Walus, A. [2020-03-31]: National Instrument 43-101 F-1 Technical Report on Del Norte Property).

Work History

The area has been explored in conjunction with the nearby LG (MINFILE 104A 161) occurrence and a complete regional exploration history can be found there.

In 2002. three holes drilled from a single location all intersected the zone at depth.

In 2003, Teuton Resources agreed to sell Lateegra Resources Corp. an option to acquire a 50-per-cent interest in the property. In 2005, a helicopter-borne AeroTEM II electromagnetic and magnetic survey was carried out on behalf of Teuton Resources Corp. over the Del Norte-Midas property and a total of 1299.5 line-kilometres was flown. In 2006, Sabina Silver Corp. completed six diamond drill holes on the LG (MINFILE 104A 161) and Kosciuzsko occurrence.

During 2017 through 2019, Teuton Resources completed programs of geochemical (rock and soil) sampling, an airborne geophysical (ZTEM and magnetic) survey and four diamond drillholes on the Del Norte property.
