The LW deposit is 2.2 kilometres east-northeast of the summit of Nickel Plate Mountain and 5 kilometres northeast of Hedley. The Canty mine (092HSE064) is about 500 metres to the north.

The area between Cahill Creek and its south-flowing tributary, Sunset Creek, is underlain by massive andesitic crystal-lithic ash tuff and siliceous ash tuff of the Upper Triassic Whistle Creek Formation (Nicola Group). These rocks are intruded by diorite and gabbro dykes and sills of the Early Jurassic Hedley Intrusions.

The deposit consists of a narrow, north-striking, vein-like zone of silicification and pyroxene flooding cut by calcite stringers, with up to 20 per cent sulphides. Most of the sulphides consist of massive arsenopyrite. Gold is associated with the arsenopyrite. One drill hole graded 2.6 grams per tonne gold over 0.76 metre (George Cross News Letter No. 238 (Dec. 12), 1988, hole GN-88-4, 72.24 to 73.00 metres). A second hole averaged 11.4 grams per tonne gold over 1.2 metres (hole GN-88-6, 23.6 to 24.8 metres).

The deposit was discovered by Golden North Resource Corporation, while exploring in the vicinity of its Canty deposit. The company drilled 13 holes totalling 1729 metres in 1988.
