The Liverpool prospect lies 1.2 kilometres southwest of the confluence of Skwum and Lawless (Bear) creeks and 10.5 kilometres west-northwest of Tulameen. The St. Lawrence prospect (092HNE065) lies about 400 metres northwest.

The area southwest of Lawless Creek is underlain by a sequence of dark grey to black pelitic schist, limestone (marble) and chlorite schist (greenstone) of the Upper Triassic Nicola Group. These rocks strike northwest and dip 30 to 70 degrees southwest towards the contact with nearby granodiorite of the Late Jurassic to Early Cretaceous Eagle Plutonic Complex. The upper part of this sequence is intruded by feldspar porphyritic dikes and sills, likely originating from the complex. Stratabound massive sulphides are developed in this area, where noncalcareous pelitic schists grade into overlying calcareous schists and marbles.

This deposit consists of a layer of semimassive to massive sulphides, 1 to 2 metres thick, hosted in grey, laminated, impure marble and underlain by quartz-chlorite-biotite schist. The beds dip 30 to 40 degrees southwest. Drilling on either side and downdip of the showing failed to intersect ore mineralization.

The sulphides consist of pyrite, chalcopyrite and pyrrhotite, with minor galena and sphalerite. They are extensively oxidized to limonite, hematite, malachite and azurite. A 4-metre chip sample taken across an exposure of limonite, hematite and malachite at the portal of an adit analysed 0.205 per cent copper, 0.026 per cent lead, 0.115 per cent zinc, 29.0 grams per tonne silver and 0.18 gram per tonne gold (Assessment Report 15419, Appendix 3, sample RAM 2R). A chip sample taken across 1.8 metres of massive pyrite, with blebs and disseminations of chalcopyrite, exposed in underground workings, assayed 0.69 gram per tonne gold, 17 grams per tonne silver and 1.26 per cent copper (Minister of Mines Annual Report 1929, page 279).

Similar mineralization is exposed in trenches on the Chicago claim (Lot 260), 200 metres to the south. Here, pyrite, chalcopyrite and sphalerite occur in limestone dipping 25 to 30 degrees west.

The limestone hosting the sulphides outcrops to the west as two northwest trending, parallel bands that may represent a single folded bed. The beds dip 40 to 45 degrees southwest. Most of the limestone is coarse grained and white, and contains relatively abundant veins and pods of quartz. Southern exposures reveal bluish grey and white banded, coarse-grained limestone with a few inclusions of schist. A sample across the width of a 150 metre long, 34 metre wide outcrop, 150 metres southwest of the Liverpool adit, analysed 53.92 per cent CaO, 0.39 per cent MgO, 1.90 per cent insolubles, 0.52 per cent R2O3, 0.32 per cent Fe2O3, 0.02 per cent MnO, 0.037 per cent P2O5, 0.008 per cent sulphur and 43.09 per cent ignition loss (Minister of Mines Annual Report 1963, page 144).

The Liverpool prospect was explored as early as 1901. The showing was periodically tunnelled by L. Marcotte and Hope Range Copper Company between 1921 and 1929. Cominco Ltd. drilled around this sulphide horizon in 1960, to determine its lateral extent. The prospect was more recently sampled and mapped by Goldwest Resources Ltd., Serem Ltd. and Bordeaux Resources Ltd. between 1980 and 1986.
