The Den showing outcrops along Lawless (Bear) and Skwum creeks, in the vicinity of their confluence, 10 kilometres west-northwest of the town of Tulameen. A body of hornblende clinopyroxenite, possibly related to the Early Jurassic Tulameen Ultramafic Complex, lies in fault contact with chlorite biotite schists and mafic volcanics of the Upper Triassic Nicola Group. The pyroxenite stock trends north for 760 metres and is up to 300 metres wide.

A feldspar porphyry inclusion occurs in the north end of the stock, on the west bank of Lawless Creek, 300 metres north of Skwum Creek. The inclusion is partly mineralized with disseminated galena and lesser chalcopyrite. Directly across the creek, a roadcut on the east bank exposes carbonatized pyroxenite with malachite staining and a veinlet of sphalerite and chalcopyrite.

A north striking, gently west dipping quartz-carbonate vein is exposed just west of the stock, 250 metres west-southwest of the confluence between the two creeks. The vein is mineralized with pyrite, chalcopyrite, sphalerite and galena across 13 centimetres, over an exposed length of 10 metres. A sample taken across 13 centimetres assayed 0.69 gram per tonne gold, 38 grams per tonne silver, 0.45 per cent copper, 0.31 per cent lead and 0.5 per cent zinc (Minister of Mines Annual Report 1960, page 51).

A second intrusive body outcrops 650 metres north-northwest of the mouth of Skwum Creek. This fine grained, felsic stock contains abundant quartz phenocrysts, and is mineralized with disseminated sulphides, including pyrite, chalcopyrite and pyrrhotite.

In 2016, a rock sample (R528) of rubble subcrop comprising a siliceous, altered intrusive with pyrite and chalcopyrite from the Den occurrence area assayed 0.125 gram per tonne gold (Assessment Report 36939).

Work History

In 1986, Fortress Resources Inc. completed a program of geological mapping, geochemical (rock, silt and soil) sampling, an airborne magnetometer and electromagnetic survey and a 9.4 line-kilometre ground magnetic and electromagnetic survey on the area as the Den claims.

During 2014 through 2018, Tech-X Resources Ltd. completed programs of geological mapping, geochemical (rock, silt and soil) sampling, 29.5 line-kilometres of induced polarization surveys and a 548.9 line-kilometre airborne magnetic survey and on the area as the Thinne and LC claims of the Lawless Creek property.
