The Lucky Strike prospect is 3.5 kilometres south southwest of Eldorado Mountain at the headwaters of Taylor Creek. The occurrence is hosted in a north trending band of serpentinite which contains knockers of greenstone, sandstone, and phyllite derived apparently from the Bridge River Complex. This serpentinite melange (Unit s), which may comprise an offset portion of the Shulap melange, is in fault contact to the east, west and south with rocks of the Mississippian to Jurassic Bridge River Complex (Open File 1989-4; Fieldwork 1988, page 119).

The Lucky Strike claim has widespread mineralization occurring in veins and fractures in dykes and in sedimentary and volcanic rocks and serpentinite. The veins are mostly narrow and faulted or feathered and pinched. The veins occur on either side of a felsic dyke at the north trending contact of cherts, to the east, and ultramafics/listwanite, to the west. The mineralized contact zone strikes 177 degrees and dips steeply west to vertical.

There are 2 adits on the property. The #1 adit, in the northwest corner of the claim, explores a nearly vertical, north striking shear zone at the contact between a 3 to 10-metre wide, coarse latite porphyry dyke and altered serpentines and "ferrigenous carbonates." The shear zone continues for 77 metres before being faulted off and contains irregular pods, lenses and streaks of sphalerite, jamesonite, pyrite, chalcopyrite, galena, massively crystalline arsenopyrite and minimal quartz gangue. Assays across 163 centimetres grade 25.0 grams per tonne gold, 96.0 grams per tonne silver and 4.7 per cent zinc (George Cross News Letter No.202, 1983).

The #2 (Coronation) adit located 200 metres southwest of #1 adit is driven south along a vertically dipping mineralized zone of contact between a carbonatized hornblende andesite dyke and surrounding serpentines. A 10-centimetre wide vein of massive arsenopyrite, jamesonite (?), sphalerite, pyrite and minor chalcopyrite occurs at the contact and quartz-carbonate-mariposite assemblages (hydrothermally altered serpentine (listwanite)) contain stringers and disseminations of sulphides for some distance from the dyke.

Samples assay up to 14.5 per cent zinc, 11.2 per cent lead, 31 per cent arsenic and 14.6 per cent antimony (Assessment Report 19686). Stibnite has also been reported.
