The Lil property is situated near the headwaters of the Lillooet River in the Pacific ranges of the Coast Crystalline belt.

Paleozoic granitic and amphibolitic gneiss, and quartz diorite of the Jurassic to Tertiary Coast Plutonic Complex underlie most of the property. Felsic to intermediate flows and pyroclastic rocks of the Pliocene to Recent Garibaldi Group cover part of the rocks. All lithologies are intruded by rhyodacite, dacite and basalt dykes. North to northeast and, occasionally, east trending shear zones are also recognized in the area. Mineralization consists of pyrite-sphalerite-galena plus/minus chalcopyrite in quartz veins and as fracture-fillings in shear zones. Disseminated pyrite is common in shears, adjacent to intrusive contacts and as an accompaniment to silicification and clay alteration. A two-metre chip sample from a shear zone in silicified and clay-altered mafic gneiss graded 2.4 grams per tonne gold, 82.3 grams per tonne silver, 0.29 per cent zinc and 0.34 per cent lead (Assessment Report 15571).
