The Lilabet showing is located 1.4 kilometres southwest of Fire Lake and 22.5 kilometres northwest of the north end of Harrison Lake.

The showing consists of a breccia zone hosted in the second member of the Lower Cretaceous Brokenback Hill Formation, Fire Lake Group. The unit consists of andesitic flows, and heterolithic volcanic breccias and conglomerates, that have been metamorphosed up to greenschist facies.

The breccia is comprised of a zone of small, white, angular, fine grained, felsic fragments in a chlorite-sulphide matrix. The zone extends northwest for 100 metres and is up to 25 metres wide. The zone contains up to 10 per cent combined pyrite, chalcopyrite and arsenopyrite. Disseminated pyrite is restricted to the felsic clasts. A chip sample taken over a length of 100 metres contained 38.4 grams per tonne silver and 1.2919 per cent copper (Assessment Report 11638, pp. 4,5, Sample AA-25091).

The breccia zone was mapped and sampled by Kidd Creek Mines in 1983.
