The Lux occurrence is located approximately 60 kilometres east of the community of Dease Lake.

The showing area is underlain mainly by Upper Mississippian to Permian serpentinized peridotite of the Cache Creek Complex. Thinly bedded limy cherts and argillaceous quartzite are reported and are probably part of the Mississippian to Triassic Kedahda Formation (Cache Creek Complex).

Minor amounts of nickel, as millerite, occurs disseminated in serpentinized peridotite. Magnetite locally forms segregations of up to 15 per cent in the serpentinite but averages about 5 per cent. Chalcopyrite occurs in a 2.5-centimetre-wide calcite veinlet in limestone near the serpentinite contact.

One rock sample assayed 20.57 grams per tonne silver and 1.85 per cent copper (ca. 1970; Assessment Report 2808). Although millerite was detected in polished section only, background amounts of nickel were reported from rock samples (values ranging from 0.19 to 0.25 per cent).

In 1970, the Lux claims were mapped and sampled by Scurry-Rainbow Oil Limited. No subsequent work is documented.
