The Lower Murex Creek occurrence is located in Murex Creek, approximately 250 metres south of its junction with McKay Creek.

The area is underlain by basaltic volcanic rocks of the Triassic Karmutsen Formation (Vancouver Group). These have been unconformably overlain by sedimentary rocks of the Upper Cretaceous Comox Formation (Nanaimo Group). Diorite and granodiorite of the Late Eocene to Early Oligocene Mount Washington Intrusive Suite (formerly Catface Intrusions) have intruded the above rocks, forming stocks, sills and dikes.

Locally, flat-lying sulphide-poor quartz vein is exposed in bedrock. The vein is 1 to 4 centimetres thick and lies at the unconformity between the Karmutsen and Comox Formations.

In 1987, a vertical drillhole, located 20 metres to the west of the showing, intersected a 2.5 centimetre thick vein yielding 14.9 grams per tonne gold (Assessment Report 19081). In 1989, a chip sample assayed 8.9 grams per tonne gold, 25.0 grams per tonne silver, 0.05 per cent copper, 0.82 per cent lead and 1.18 per cent zinc (Assessment Report 19081). Float samples, from further down the creek, of pyrite and sphalerite bearing drusy quartz vein material yielded values up to 149.1 grams per tonne gold and 92.6 grams per tonne silver (Assessment Report 19081).

During 1986 through 1993, Westmin Resources completed programs of prospecting, geological mapping, geochemical sampling and airborne and ground geophysical surveys on the area as the Ideal 1-9 and Harmony claims.
