The showing, discovered by the Daykin brothers, in 1906, is located on the western shore of Collison Bay.
In 1910, the Wireless and Telephone claims were owned by Daykin and Metcalfe. In 1911 a 15-metre crosscut adit was driven at sea-level to the vein. In 1973 Barrel Resources Ltd. held 40 claims in the Itsa and CU groups, covering the southern and western shores of Collison Bay and including several old properties. Work done over the area included linecutting and magnetometer survey, 1.4 kilometres; electromagnetic survey, 0.8 kilometre; geochemical soil survey of 97 samples taken on a 30 by 61-metre grid spacing.
The area is underlain by Vancouver Group, Upper Triassic Karmutsen Formation consisting predominantly of basalt and interlava limestones. Diorite of the Collison Bay Stock, part of the Middle to Late Jurassic Burnaby Island Plutonic Suite, lies to the east of the showing. Disseminated chalcopyrite and bornite occur as a bedded replacement of a thin interlava limestone. The bed strikes 025 degrees and dips 045 to 050 degrees northwest and is up to 1.2 metres thick. A 3-metre chip sample from the adit assayed 2.0 per cent copper, 41.8 grams per tonne silver and 1.0 gram per tonne gold (Assessment Report 14189).
Between 1916 and 1917 approximately 15 tonnes of ore was shipped from this property. From this ore 361 kilograms of copper with 435 grams of gold and 374 grams of silver were recovered.
