The Lu occurrence is located approximately 80 kilometres east of Dease Lake.

The region of the Lu showing is underlain by upper Permian to Lower Triassic Cache Creek Complex rocks including volcanic, metavolcanics (greenstone), metasediments, gabbro and tectonically emplaced upper Mississippian to Permian ultramafic rocks. The Cache Creek ultramafic rocks consist of peridotite, dunite and pyroxenite which are generally serpentinized.

A 1985 prospecting program by Getty Canadian Metals is the only documented work on this ground. The Lu property is reported to be underlain mainly by phyllite and mafic to intermediate volcanic rocks of the Mississippian to Triassic Kedahda Formation or upper Mississippian to Permian Nakina Formation, both of the Cache Creek Complex.

Quartz veins are common in the volcanic rocks pinching and swelling up to 2 metres in thickness. Most contain trace amounts of chlorite, epidote, pyrite, chalcopyrite, malachite and arsenopyrite. A 10 centimetre wide quartz vein containing pyrite assayed 0.77 gram per tonne gold; in the same area, several samples of silicified greenstone assayed 0.03 to 0.14 per cent copper (Assessment Report 14136).
