The Echo showing, on the Echo 1 and 2 claims, is located 4 kilometres south of Honeymoon Bay on Cowichan Lake, just north of Nineteen Creek.

The area is underlain by a succession of basaltic tuffs, feldspar porphyry basalt, crystal tuffs and basalt of the Lower Jurassic Bonanza Group intruded by diorite of the Early to Middle Jurassic Island Plutonic Suite.

Mineralization, consisting of malachite and chalcopyrite, occurs in a 6.5 metre zone within a main shear zone in basaltic tuffs. The zone comprises a network of irregularly branching shears, 5 to 12 centimetres in thickness. The shears are irregularly spaced and, on average, strike 066 degrees and dip 63 degrees east. Abundant small fractures and secondary shears, striking between 245 and 272 degrees and dipping 65 to 80 degrees north, are coated with malachite and iron oxides. Locally, up to 25 per cent of the sheared rock material is malachite.

To the northwest and west, the shear zone and host tuffs are cut by a complex network of 1 to 5 millimetre thick, calcite-filled fractures and shears.

The occurrence was first discovered in 1957 by prospector Walter Dean. In 1981, Pace Industries prospected the property. In 1985 and 1986, Orbex Industries completed a program of prospecting and geochemical sampling. A total of fourteen 0.5 kilogram samples were taken from random rock chip sampling conducted over an area 2 metres wide and 2 metres high of the mineralized shear zone. The samples assayed between 0.35 to 218.6 grams per tonne gold, 0.52 to 3.15 per cent copper and 5.0 to 42.5 grams per tonne silver (Assessment Report 14996). In 1993, Consolidated Ramrod Gold Corp. completed a program of geochemical sampling and four diamond drill holes, totalling 293.6 metres. Detailed sampling of the cores (161 samples) yielded low gold, copper and silver values.
