The TJ occurrence is located on a ridge separating Hushamu Creek and the northwestern headwaters of Youghpan Creek, approximately 4.5 kilometres southeast of Hushamu Lake.

Regionally, the area is underlain by northwest-trending belts of basaltic volcanics and carbonate sedimentary rocks of the Upper Triassic Karmutsen and Quatsino formations (Vancouver Group) and mafic volcanics and sediments of the Upper Triassic to Lower Jurassic Bonanza Group (Holberg volcanic unit, Nahwitti River wacke and Parsons Bay Formation). These volcanic and sedimentary rocks have been intruded by granodioritic rocks of the Early to Middle Jurassic Island Plutonic Suite.

Locally, weakly chlorite-altered andesitic flows and tuffs host two planar to irregular stockwork quartz veins, 10 and 7 metres wide, respectively, with local chalcopyrite, sphalerite and galena mineralization. The veins are orientated at 060 and 360 degrees. Calcite and pyrobitumen are also reported.

In 2005, rock chip samples yielded up to 11.70 grams per tonne gold, greater than 200 grams per tonne silver, 0.583 per cent copper, 1.070 per cent lead and 1.210 per cent zinc (sample 380064; Assessment Report 28375).

The area has been explored since the 1960s in conjunction with the nearby Hushamu (MINFILE 092L 240) occurrence. In 2005, Luminar Resources Corp. completed a program of rock, silt and soil sampling, geological mapping and a 2687.0 line-kilometre airborne electromagnetic survey on the area.
