The Gold Dyke showing is located 2.5 kilometres south of Caycuse on the southern shore of Cowichan Lake. The Eagle showing (092C 145) is just to the south.

The area is underlain by southeasterly dipping Lower Jurassic Bonanza Group intermediate to felsic volcanic rocks. These are cut by numerous faults infilled with quartz-carbonate material.

Drilling in 1986 revealed pyrite, galena, sphalerite and trace chalcopyrite and arsenopyrite in drill core. Pyrite, 1 to 20 percent, and trace chalcopyrite is disseminated throughout the rock units. Generally associated with more siliceous zones, coarse sphalerite and galena (up to 4 per cent) occur disseminated in quartz-carbonate and siliceous veins. The siliceous veins are up to 0.10 metres wide. Associated with vuggy portions of quartz-carbonate veins, arsenopyrite occurs in irregular masses.

A sample from DDH 213-4, from the 78 to 80.47 metre interval, of quartz-carbonate veining in porphyritic andesite, assayed 1.389 grams per tonne gold, 2 grams per tonne silver, 1.5 per cent lead and 1.04 per cent zinc (Assessment Report 15821). This was the highest assay result.

Geochemistry suggests that mineralization may extend another 100 metres to the east and is open to the west.
